Commodity Investing and Trading (Stinson Gibner)

advertisement
Yet those studying, trading and regulating
these markets know that such deceptively
simple descriptions cannot explain the subtle
dynamics that drive supply and demand.
To be sure, China’s growth, industrialisation
and consumerism have led to soaring demand
for everyday commodities: China now
accounts for over 40% of the demand of the
world’s iron ore, copper, and other metals.
But commodity markets are now part of the
integrated global financial system - buffeted
by demand from growing emerging-market
economies as much as by cash-rich funds
eyeing commodities as an asset class.

Commodity markets are an indelible
element of financial markets and of society.
For thousands of years they have shown
themselves to be the most efficient way to
assign the elemental resources
necessary to advance. This fundamental
quality has not changed.
What has changed is the breadth,
depth and complexity of markets.
Chapters focus on the fundamentals
of major, key markets:
• oil and petroleum
• metals
• natural gas
• power
• weather
• grains and oilseeds
• coal.
Edited by Stinson Gibner
Editor Stinson Gibner brings two decades of
experience to Commodity Investing and Trading,
having cut his teeth at Enron, Citadel, and
Citigroup. He has assembled a team of industry
experts whose contributions give the reader
a unique view of the commodity markets.
Subsequent chapters detailing risk management,
trading, and market insights including:

Introduction
Stinson Gibner
Whiteside Energy
Strong gains in commodity prices since the early 2000s created a
growing interest in the asset class. The financial industry responded
with many products, including new hedge funds, index funds,
commodity-linked fixed income products and exchange-traded
funds (ETFs). With oil and natural gas making a prominent peak in
2008 and gold hitting a peak in 2011, many took this as a sign that the
commodity bull had run its course and expected that we would
return to the normal long-standing trend of commodity price deflation.
The deflationist camp notes that growth in China must slow
down, possibly to a dramatic degree, if imbalances in that economy
are not handled carefully. Europe and the US continue their struggle
to reignite sorely needed jobs growth in order to relieve high youth
unemployment, while at the same time facing demographics that
lead to a shrinking labour force.
However the world’s economic situation is resolved, commodities
and commodity flows will remain critical to the functioning of cities,
states and economies. For this reason, a basic knowledge of the
supply and demand issues relevant to each commodity sector
provides financial insights even beyond the commodity markets.
This book therefore discusses the fundamentals of many of the major
traded commodities offering both an introduction and a reference
for all those interested in understanding and analysing these
markets.
This book is divided into three sections. The first covers the fundamentals of the most important markets in energy, metals and

agriculture. Michael S. Haigh starts us off with an investigation into
the importance of non-fundamental information. He uses principle
component analysis to discover how commodity market behaviour
has changed over the years, and shows evidence that commodity
market participants have adjusted their behaviour since the financial
crisis of 2007–08.
Within the energy complex, crude oil, European power, North
American power, natural gas, liquefied natural gas (LNG), and coal
are covered in separate chapters. Chapter 2 by Stinson Gibner
provides an introduction to the fundamentals of the North American
market for natural gas. Natural and economic forces impacting
supply are illustrated along with the annual rollercoaster of demand.
The critical role of storage in balancing short-term and seasonal
swings is explained, and key issues for the supply–demand balance
are discussed. Also within this chapter, Rita D'Ecclasia gives an
overview of the expanding global LNG trade.
Relevant to all commodities, Jose Marquez discusses weather and
climate from the unique perspective of a working commodities meteorologist. His chapter walks through the daily analysis and
information flow that must be monitored to keep abreast of weather
impacts on commodity demand and supply, while a panel discusses
climatology and its longer-term indicators of weather trends.
In Chapter 4, Todd Gross tells the incredible story of how oil prices
climbed from US$17/bbl in 2002 to an amazing US$147/bbl a mere
six years later. Todd also examines, as he puts it, “why the globe
always seems to be running out of oil, and yet, so far, that fate has yet
to be realised.” Unafraid of digging into the details, the analysis of
global refining capacity gives a great insight into the changing
demand for – and flows of – various types of crude. The impact of
transport bottlenecks within North America is also discussed.
William Webster then explains the unique challenges of operating
a market for power, and explores the solution adopted by the
European power market. He explains the instruments traded and
price formation, before offering a historical perspective of pricing for
these markets. He concludes with thoughts about possible future
market trends and regulatory changes.
Kamal Naqvi takes us on a whirlwind tour through the precious,
base and industrial metals in Chapter 6, in which he discusses the
key drivers for metals and offers insights as to which may outperxviii

INTRODUCTION
form going forward. In Chapter 7, David Stack provides a tour de
force discussion of the global grains markets, giving an overview of
the markets for food grains, feed grains and oilseeds. Farming area,
yield and production trends are discussed for major producers. The
chapter also reviews past import and export flows, as well as likely
future trends for global grain flows and crop rotation flexibility. A
discussion of the coal markets in Chapter 8 completes the energy
commodities. Jay Gottlieb lays out the fundamentals of the coal
markets and discusses which trends are likely to dominate going
forward.
Rounding out agricultural investments, Greyson Colvin and Marc
Schober open the second section of the book by explaining the basics
of agricultural land in Chapter 9, arguing that the fundamentals
behind the rush to invest in farmland are likely to persist far into the
future. Complementing the grains discussion, Chapter 10 by Patrick
O’Hern explores the agricultural trading and hedging markets and
gives an overview of the types of participants active. He provides
several examples of trading strategies to illustrate intra-market and
cross-market trade opportunities within the agriculture markets,
and illustrates the diversification that may be provided across
commodities.
The remainder of the section on trading and investing strategies
focuses on alpha strategies and index investing. In Chapter 11, Mark
Hooker and Paul Lucek present an interesting case study of what
they call convergent and divergent strategies, concluding that useful
risk diversification can be achieved through intelligent choice of
strategies within a commodity portfolio. An overview of alpha
strategies that could be used by either traders or index funds is given
by Francisco Blanch and Gustavo Soares in Chapter 12, which covers
momentum, roll yield and volatility methods. The accompanying
panel by Paul Kaplan gives a short case study of active index funds
applying these alpha concepts.
In Chapter 13, Kostas Andriosopoulos finishes out the commodity
index investing discussion by bridging the gap between commodities and equities. It presents his proposal to track a spot commodity
index by using a carefully selected portfolio of equities, and shows
his tested selection methods and tracking results.
The third section of the book opens with two chapters by Carlos
Blanco. In Chapter 15, Blanco and Michael Pierce present the choices

for performing a proper analysis of credit risks embedded in your
bilateral trade portfolio. The resulting credit value adjustment (CVA)
provides a measure of expected future loss due to credit events.
Taking a broader view of risk, Chapter 14, also written by Carlos
Blanco, explains the structure for putting in place a system of enterprise risk management and some possible pitfalls. In principle,
everyone wants to have proper risk systems and structures in place;
however, operational weakness is difficult to avoid as daily choices
must be made between risk levels and the potential profitability of
the enterprise. Carlos explains the challenges of the risk manager
and offers advice about properly structuring a risk management
function.
Wang Xueqin then reviews the rapid growth of commodities
trading in China in Chapter 16, and shows that although still largely
restricted to domestic participants, the size of China’s commodity
futures markets now rivals commodity markets globally.

The Impact of Non-fundamental
Information on Commodity Markets
Michael S. Haigh
Société Générale Corporate and Investment Bank
Commodity markets can (and will) occasionally co-move with
broader macro markets for reasons beyond the physical fundamentals. The purpose of this chapter is to illustrate how different
commodities are affected by non-fundamental factors (macro shocks,
liquidity events, currency moves and broader market sentiment
swings) that are normally considered exogenous to commodity
fundamentals (eg, mine or oil supply). At certain points in time, especially since the Lehman bankruptcy in September 2008, the
non-fundamental influences on certain commodities have dwarfed
the impact of actual commodity fundamentals. Accordingly, understanding this has brought obvious benefits for analysing how
commodity market price moves can be applied to trading strategies.
The chapter will examine this by focusing on energy (oil), base metals
(copper) and precious metals (gold), and agriculture (soybeans).
Until the late 1990s, commodity markets generally enjoyed excess
capacity as innovations and new discoveries resulted in greater
supply (think of how the US natural gas markets have evolved). Any
supply side shock that was persistent would result in commodity
price increases, higher inflation and a consequent decline in equity
markets: hence the negative relationship with commodity price
movements. However, by 2000, increased demand growth and
underinvestment in the supply chain meant the excess capacity was
slowly absorbed. By 2008, the underinvestment in activity became
more evident as the credit crisis resulted in suspensions and cancella3

tions of hundreds of commodity projects. As such, changes in global
economic activity, Purchasing Manager’s Index (PMI) strength, dollar
strength and changes in inflation expectations (resulting from quantitative easing) are playing a much larger role in commodities.
Given the increased influence of “non-fundamental” information
on commodity markets, it is worthwhile to quantify as accurately as
possible the level of this influence, across commodities and across
time. To thoroughly assess the role of non-fundamentals during
episodes of quantitative easing, we employ the principal component
analysis (PCA) technique. Simply stated, PCA is the analysis of the
covariance matrix and can be used to analyse multi-assets: baskets
made up of commodities, other financial indicators, volatilities, etc.
From the historical data, the analysis determines the principal
components of the covariance matrix – ie, the way in which the asset
price movements correlate, by order of importance. To conduct PCA
on commodity prices, we analyse price data for a variety of
commodities against a diversified basket of 28 assets across markets,
including: volatility indexes (EU and US), credit (EU and US and HY
versus IG), FX (dollar, yen, euro, carry trade (G10 and EM)), bonds
(spreads, 10Y GVT and inflation break-even), equities (BRIC, Euro,
emerging, EU and US) and global indexes. Factors are estimated
using the 28-member basket, which means each factor is a weighted
average of the 28 assets with different weights for each factor.
The model estimated three main explanatory factors: macro,
dollar and liquidity. What is not explained by these factors (the residuals) is interpreted as the commodity fundamentals. Depending on
the commodity, the relative importance of each factor varies considerably, as does the influence on commodities of all the factors
combined. Moreover, extreme events (eg, Lehman Brother’s bankruptcy) have structurally altered the influence of the macro factor (in
particular) and largely demoted the dollar factor to a secondary
“outside” influence on the commodity markets.
Energy
Here we focus on Brent and note that, unsurprisingly, Brent’s fundamentals in terms of explanatory power began to deteriorate
(consistently) in 2007 when the subprime crisis became a reality (see
Figure 1.1). In the early 2000s, fundamentals prevailed with 80–90%
explanatory power (eg, in March 2002, dollar and liquidity explained

roughly 10% each of Brent’s price movements). The Lehman bankruptcy changed this, with fundamentals’ explanatory power
dropping to the 30–40% range, on average. Since 2013, we have seen
Brent’s fundamentals progressively giving up explanatory power to
the macro influences as inventories increase, alleviating concerns of a
shortage (see Figure 1.2). The dollar’s influence has latterly been

Base
Prior to the Lehman crisis, the bulk of the explanatory power relating
to base metals price movement was explained by fundamentals (for
both copper and aluminium (not shown)), followed by movements
in the dollar. The role of fundamentals diminished post-Lehman
with more explanatory power coming from the macro factors and
much less from the dollar (see Figure 1.3). Copper is the one base
metal that is very exposed to the macro outlook, especially as price
levels have become significantly higher than the marginal cost of
production. Not surprisingly, prices can be significantly influenced
by other factors. In late 2012, the role of macro dropped in its
explanatory power (Figure 1.4).
Precious
The gold market remains an outlier among commodities (not
surprisingly), with the influence from non-fundamentals still coming
from the dollar, and liquidity and macro factors jostling for second
place in terms of explanatory. Since Lehman (Figure 1.5), liquidity
has improved in terms of extra explanatory power of gold price
movements. Since late 2012, the “outside influences” have diminished (see Figure 1.6), coinciding with gold prices plummeting in
early April 2013.

The market’s fundamentals (here represented by soybeans)
accounted for approximately 70–95% of price volatility prior to
Lehman (see Figure 1.7). The remainder of the price movement was
captured mainly by the dollar (after the early 2000 recession).
Nevertheless, soybeans could not avoid the influence of the Lehman

lesser the impact of “outside” factors on commodity markets.
Agriculture continues to be the most independent of the markets
(alongside natural gas), relying mainly on its own fundamentals.
Structurally, we have seen a shift in all markets (except gold)
whereby the role of the US dollar in terms of explanatory power has
dropped dramatically, to be replaced by the role of macro factors.
THE SG SENTIMENT INDICATOR VERSUS COMMODITIES
The job of assessing commodity price movements becomes difficult
when macro, dollar and liquidity dominate. It becomes even more
difficult when prices are pulled around by market sentiment.
Fortunately, we can assess the role of sentiment employing a sentiment indicator – a tool used to gauge an average level of risk
experienced throughout the global markets. Although the methodology is intuitive and simple, each step must be analysed to provide
a clear understanding.
Our sentiment indicator is built in three steps. First, suitable financial market variables, expressing a clear connection with risk, are
selected. The following variables have been selected as input risk
factors: equity volatility (VIX index), FX volatility (average of G4 3M
volatility), interest rate volatility (average of G4 1m1y and 1y5y
swaptions), credit spreads (iTraxx index), swap spreads (2y, G4
average) and the ratio of gold to gold equity. Second, the scoring
9
01 Chapter CIT_Commodity Investing and Trading 25/09/2013 15:43 Page 10
COMMODITY INVESTING AND TRADING
technique is developed. Of the six variables selected, a score is
assigned depending on the current value of the variable over the
time horizon. Each day, the variables are sorted based on the last 30
days of data, and are assigned a score of one if they have the highest
value in the past 30 days (extreme “risk off”) or two if they have the
second highest value, all the way to 30 for the lowest value. Last, a
simple weight of 1/6 is assigned to each of the variables. The average
of the six scores is linearly projected in the interval 0–1, with
low/high values representing risk aversion (“off”) if the sentiment
indicator falls below 0.35, risk-seeking (“on”) sentiment (above 0.7)
and risk neutral (between 0.35 and 0.7). These bands can be seen in
Figure 1.9 and illustrate the strong connection between the Dow
Jones-UBS (DJUBS) commodity index and the sentiment indicator.
In addition to the 30-day sentiment indicator, here we develop a
100-day and a 252-day sentiment indicator for a commercial application. The methodology/scoring method is identical, but the
look-back period is 100 days and 252 days, not 30. The reason for a
longer look-up is intuitive. Imagine a scenario where commodity
prices are trending down, say, for 60 days. The 30-day sentiment
indicator has to turn upwards within those 60 days because the
scoring is based on the last 30 days, and so even in a declining market
the sentiment may rise. In this sense, the 30-day sentiment indicator
is a short-term indicator, and we develop the 100-day and 252-day
indicator to assess medium- and longer-term trends. Obviously, with
the 100-day indicator the sentiment is less volatile and would enable

an investor to hold positions for longer (as the investment is based on
sentiment) and incur lower trading costs from rebalancing.
Overlaying with an even longer timeframe (252 days) would add a
further layer of security, ensuring that in periods of extended risk
aversion one does not see a return to risk seeking prematurely,
which may be signaled by a 30-day indicator. Regardless of the lookback period, the methodology is simple and its relationship to
commodity prices extremely strong. Indeed, it is difficult to find a
daily indicator with such a strong short-term relationship to almost
every commodity within the DJUBS (see below).
SENTIMENT CAUSES COMMODITY PRICES AND NOT THE
OTHER WAY AROUND
Of interest is the question of causality and the speed of response of
the DJUBS to changing sentiment. To this end, we estimated a
reduced-form five lag VAR (vector-auto-regression) using daily
(stationary) data from early 2007 to mid-2012 (technical details
excluded to conserve space). Resulting causality tests confirm at very
high levels of confidence (5%) that sentiment “causes” DJUBS price
movements, and not the other way around. Here we can take the
causality analysis one step further with the assistance of impulse
response functions. We shock our VAR model by one standard deviation (down) and trace out the influences of sentiment on the DJUBS
price path, and vice versa. Focusing on Figure 1.10, we see that a one

standard deviation decline in sentiment results in a negative price
path for DJUBS – ie, it also declines. What is interesting, however, is
the speed of that response and the time it takes for DJUBS to fully
incorporate the negative sentiment.
The first day after the shock (day 1) DJUBS prices react, but by day
five, DJUBS has declined by the same amount, in percentage terms,
as the negative sentiment. Beyond day five, DJUBS returns to its preshock level. The equivalent decline in DJUBS prices (one standard
deviation) does not have a significant influence on sentiment (but
raises it modestly) – see Figure 1.11.

Measuring the relationship between variables at various points in
time, rather than using a single correlation coefficient over the entire
sample period, provides information on the evolution of the relationship dynamically. For this purpose, simple correlation measures such
as rolling historical correlations and exponential smoothing are
widely used. The rolling historical correlation estimator provides
equal weights to newer and older observations, and raises issues
surrounding window-length determination. The exponentialsmoothing estimator requires the user to adopt an ad hoc approach to
choosing the smoothing parameter. The dynamic conditional correla12

tion (DCC) methodology developed by Engle (2002) helps to remedy
both of these issues.1 In the first step, time-varying variances are estimated using a general autoregressive conditional heteroscedasticity
(Garch) model. In the second step, a time-varying correlation matrix is
estimated using the standardised residuals from the first-stage estimation. Here, we use the DCC method because it has been shown to
outperform other widely used correlation structures in helping with
portfolio investing decisions.2 To assess the relationship between
commodities and sentiment, we correlate the rolling nearby futures
contract prices (using log returns) for each component of the DJUBS
with the 30-day sentiment indicator with daily data beginning in
September 2006. Importantly, the results are qualitatively very similar
when we correlate the DJUBS component prices with the 100-day
indicator (results excluded to conserve space).
Figures 1.12 and 1.13 plot the time-varying correlation of the log
returns of aluminium (LHS) and copper prices (RHS). September 15,
2008 (Lehman bankruptcy) was a game changer – there is a noticeable shift in the relationship between the base metals markets and
sentiment. For aluminium, the average correlation tripled (from 0.13
to 0.38) with the maximum correlation post-Lehman reaching 0.59.
The minimum correlation post-Lehman was 0.15, still higher than
the average pre Lehman. In the case of copper, the correlation
increases from an average of 0.11 to 0.42, almost four times higher
post-2008. Interestingly, the volatility of the correlation of copper

and sentiment is half that of aluminium, post-Lehman. Turning now
to the energy markets, here represented by Brent and heating oil, the
results also illustrate a structural break. Pre-Lehman, the Brent correlation was a mere 0.08, post-Lehman it was 0.39 (see Figure 1.14). For
heating oil (Figure 1.15), we see the correlation rise from an insignificant 0.04 to 0.38.
At first glance, the results of gold and sentiment may appear counterintuitive, as their average correlation pre-Lehman was 0.06 (see
Figure 1.16). While low, their post-Lehman correlation (relative to

other markets) is not much higher at 0.18, on average. Interestingly,
for both gold and silver, the Lehman event did increase the correlation, but it was not a structural change, in the way it was for the energy
and base metals markets. However, gold is a unique commodity,
driven as much by sentiment, macro and the dollar as by its own
fundamentals (eg, central bank involvement, exchange-traded fund
15
01 Chapter CIT_Commodity Investing and Trading 25/09/2013 15:43 Page 16
COMMODITY INVESTING AND TRADING
(ETF) volumes, jewellery and coin demand, mining and scrap
supply), so a decrease (increase) in sentiment may result in an increase
(decrease) in gold demand, hence dragging their correlation lower.
Gold is often negatively related in periods of extreme crisis, hence
fulfilling its role as a flight to safety. Post-Lehman, and after the
August 2011 euro crisis, there has been a negative correlation with
sentiment. This is less evident in silver (Figure 1.17), the more industrial of the two precious metals. Its correlation rose from an average
of 0.16 pre-Lehman to 0.30 post-Lehman.
Not surprisingly, the role of sentiment is not as important to the
agricultural markets despite their reacting to the Lehman crisis in the
same way as the base metals and energy markets (albeit at a much
lower level). The scale of the axis hides the subtle nature of the
change: it was very low in the case of corn (Figure 1.18). From a preLehman correlation of 0.13, we only see a rise to 0.16. Hardly
significant, for coffee we see a rise from 0.10 to 0.22, a doubling of the
correlation (Figure 1.19).
Not shown (to conserve space) is the change in the relationship for
wheat. The correlation before Lehman was actually negative, on
average; post-Lehman, it averages 0.19. Therefore, agriculture –
which was less influenced, certainly in the short run, by the euro
crisis, or by a slowdown in Chinese demand which would influence
the more cyclical commodities – as with base metals and energy, is
not going to be as affected by things outside of its own fundamentals.
As we have illustrated, agriculture markets are still positively related

to sentiment and are still part of global benchmark indexes, but sentiment’s influence on them is certainly lower.
Last, we present a couple of examples of markets that did not
change after Lehman. US natural gas (a domestic rather than global
market) is the distinct outlier in that its correlation pattern did not
change at all with the structural change in 2008 (see Figure 1.20). Its
average correlation remained at 0.06, precisely the same value it had
before the crisis in 2008. Lean hogs is also independent of sentiment,
having a very similar correlation value pre- and post-Lehman (0.06
and 0.05). Its correlation can occasionally go negative (Figure 1.21).

THE IMPACT OF NON-FUNDAMENTAL INFORMATION ON COMMODITY MARKETS
DO SOME COMMODITIES REACT MORE TO SENTIMENT IN
“RISK-OFF” VERSUS “RISK-ON” ENVIRONMENTS?
We conclude our analysis of the relationship between commodities
and sentiment by digging deeper into the relationships during
periods of “risk off”, “risk neutral” and “risk on” before the Lehman
crisis (see Table 1.1, left-hand side) and post-Lehman (right-hand
side). First, we present the rankings from the 30-day sentiment indicator in Table 1.1. Prior to the Lehman bankruptcy (left-hand side),
the top 10 commodities most correlated with sentiment in “risk off”

were represented by all commodity types: base metals, precious
metals, agriculture and energy. In fact, energy only just makes the
top 10, with West Texas Intermediate (WTI) ranked ninth in terms of
its correlation with sentiment in “risk-off” environments.
When we focus on the post-Lehman period, the patterns change
considerably. The top 10 most-correlated commodities with sentiment are base metals and energy and silver (which one could argue
is somewhat of an industrial metal). There are no more agricultural
commodities at the top (with “risk off”) until we get to number 10:
soybean oil (which moves into number nine (just) in “risk-on” environments). Moreover, regardless of the environment, “risk on”, “risk
neutral” or “risk off”, the rankings of commodities hardly change
post-Lehman. The most “significant” change is aluminium, which
moves from being the most correlated with sentiment in “risk off” to
being the fourth most correlated in “risk off”: a relatively minor
change. Compare this to gold, for example, pre-Lehman. Its ranking
changes from the seventh most correlated with sentiment in “riskoff” to 18th in “risk-on” environments. The bottom line is, with
changes in sentiment, base metals and energy are much more influenced by sentiment than other types of commodities post-Lehman.
BRINGING IT TOGETHER: A SIMPLE OVERLAY EXAMPLE TO
THE DJUBS
In this section, we will illustrate how to incorporate the main results
from our research into a simple product for investors wishing to
benchmark against the basic DJUBS (excess return) long-only exposure. There are obviously numerous applications, but for clarity and
simplicity we focus on a simple overlay. We simply try to incorporate a medium-run sentiment indicator (100-day) to help with
re-weighting overlaid with a longer-term indicator (252-day) to
provide a further layer of insurance in periods where prices fall for a
long period of time. Critically, this is just an example and many other
applications can be made. Here is the procedure.
❏ First, we develop two sentiment indicators based on the principles outlined in the previous section. One is the sentiment
indicator based on the 100-day look-up period to signal reweighting decisions (to reduce trading costs that occurs to
shorter-run indicators). The second sentiment indicator has a
20
01 Chapter CIT_Commodity Investing and Trading 25/09/2013 15:43 Page 21
THE IMPACT OF NON-FUNDAMENTAL INFORMATION ON COMMODITY MARKETS
252-day look-back period. The 252-day sentiment indicator is
going to behave differently than the 100-day indicator as it incorporates a much longer-term risk appetite. Therefore, the 252–day
indicator provides insurance for periods of extended
declines/risk aversion that even the 100-day indicator might not
pick up on.
Second, using the 100-day indicator, we focus on weight tilting

example), the investor sits on the sidelines until long-term sentiment improves (ie, passes through 20% to the upside), at which
point the risk-tilting mechanism kicks in once more.
Importantly, while we have isolated the commodities most affected
by sentiment as the ones to remove in “risk off” versus capture in
“risk on”, even the less-sensitive commodities are positively correlated with sentiment. Therefore, one could argue to completely
remove all commodity exposure in “risk off”, but here we choose to
remain invested instead of having extended periods of time sitting
on the sidelines. Performance is clearly better overlaying the sentiment (see Figure 1.22), a function of re-weighting and overlaying
with an extra layer of insurance (the 252-day window). Focusing
purely on the September 2008 onwards (47 months), the number of
positive months increases from 27 to 32 and average annualised
return rises from –13.34% investing in the DJUBS (about –3.52%
annualised) to 74.08% (about 15% average annualised) investing in
the DJUBS, weight-tilted 100-day sentiment indicator with the 252day overlay. Ignoring the 252-day overlay (from sentiment) results in
a return of 32%. Therefore, most reward from using the sentiment
indicator comes from the performance attributed from shifting
weights based on the 100-day indicator (about 45% over the DJUBS),
although the overlay (insurance) adds almost the same amount. The
number of times the portfolio is re-weighted because of a change in
sentiment is approximately 25 times per annum. With the 30-day
sentiment indicator applied (instead of the 100-day), the number of
times is 46 – hence higher trading costs.
SUMMARY
It is clear that outside influences on commodities have picked up
since 2008. The role of macro, dollar and liquidity vary across
commodities and across time. Sentiment has made a substantial
impact on the commodities markets since 2008. Here, we have documented the causal relationship (from sentiment to commodities) and
reported that some commodities are more affected by sentiment than
others. A ranking was established. We applied our research results
by overlaying the DJUBS with the sentiment indicator signals, utilising the rankings of the sensitive commodities by re-weighting in
“risk-off” and “risk-on” environments. The re-weighting alone

significantly outperforms the long-only DJUBS exposure since 2008 –
we achieve an extra 45% higher return over the period. However,
overlaying with an extra layer of protection (a signal from a 252-day
sentiment indicator) significantly protects returns from large
declines in commodity prices – this adds an additional 42% on top of
the 45%. Total returns using weight tilts and 252-day overlay equals
74.08% since 2008, compared to –13.34% by investing the DJUBS.
The purpose of this chapter is not to suggest fundamentals do not
matter – they do, but what is clear is that an analysis of commodity
markets requires something more than counting barrels or bushels.
Even basic applications of sentiment onto commodity markets add
outperformance and significant protection.

The North American Natural
Gas Market
Stinson Gibner
Whiteside Energy
This chapter will provide an overview of the most important supply
and demand developments for natural gas, beginning with a brief
discussion on natural gas and how it is traded. The analysis of gas
demand fundamentals and gas production leads to an understanding of the dynamics of the storage market for natural gas. The
geographic distribution of sources and demand for gas will also be
examined, before we move on to price dynamics, aided by examples
of how many of these factors influence market prices for gas. In
conclusion, key factors that will determine the future evolution of
prices are identified.
OVERVIEW
What makes the North American natural gas market unique? The
most important factor is that it is a self-contained system within the
confines of North America, apart from limited liquefied natural gas
(LNG) import and export capability. Consequently, the market can
by analysed by understanding supply, demand and storage stocks
within the US and Canada. LNG imports can be relevant, but having
been at less than 2% of the annual supply for many years, they have
little market influence.
Highly seasonal demand driven by winter heating and a lesser
peak from summer cooling loads combines with relatively constant
production flows to require massive storage facilities that can inject
gas during times when supply outpaces demand and withdraw
25
02 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:37 Page 26
COMMODITY INVESTING AND TRADING
when gas burn rises. Injections and withdrawals from storage facilities are surveyed and reported by the Energy Information
Administration (EIA), part of the US Department of Energy (DOE),
providing a closely watched weekly monitor of supply/demand
balance.
The natural gas transported through long-haul pipelines is
primarily methane with a mixture of some ethane and smaller
amounts of heavier hydrocarbon gases, and may contain a small
percentage mixture of nitrogen and carbon dioxide. The average
heating value of gas consumed in the US is now about 1,025 Btu per
cubic foot or 1.025 million Btu (MMBtu) per thousand cubic feet
(Mcf). This leads to an often-used rule of thumb conversion factor
that 1 Mcf approximately equals 1 MMBtu. Pipelines have specifications for the range of gas quality acceptable for receipt. The heating
value of the gas accepted must typically lie within a range of, for
example, ~970–1,100 Btu per cubic foot. Some of the most common
natural gas units of measure and conversions are given in Table 2.1.
GAS MARKETS
Before the 1990s, natural gas purchases and sales were predominantly handled by long-term contracts for physical natural gas.
Natural gas can still be traded by the purchase or sale of physical gas
where the seller delivers and the buyer receives the molecules, and
there is also a liquid market where gas can be traded purely finanTable 2.1 Common units of measure and conversions

cially. Most financial market instruments derive from the traded
structures in the physical gas market.
The physical gas market traditionally trades gas for both monthly
and next day delivery. Purchases of monthly gas are for gas to be
delivered in approximately equal daily quantities over an entire
calendar month. The majority of these physical gas purchases and
sales are made during “bid week”, the last week of each month. Gas
also trades in the daily market, with purchases and sales of gas typically occurring during the morning hours prior to the gas flow date
in order to allow time for proper nominations for gas flows on the
required delivery pipelines. Gas for the weekend and Monday are
traded on the preceding Friday.
The Nymex natural gas futures contract was introduced in 1990,
and it rapidly grew in traded volumes. The contract can be physically settled at the Henry Hub in southern Louisiana, which allows
for the interchange of gas between 13 pipelines, or at an alternate
delivery point based on mutual agreement between the buyer and
seller. Monthly futures contracts are listed, each contract unit representing 10,000 MMBtu, with the contract price quoted in US$/
MMBtu and having a tick size of US$0.001 (0.1 cent) per MMBtu.
Although many months of futures are listed, liquidity concentrates
at the front of the futures curve. In addition to trading on the Chicago
Mercantile Exchange (CME), Henry Hub futures are listed on the
IntercontinentalExchange (ICE).
Of course, gas trades, both physical and financial, for many
delivery locations throughout North America other than Henry
Hub. In order to facilitate these transactions, a large number of gas
price indexes have been created. The primary publishers of these
indexes are Platts and Natural Gas Intelligence. Each of these
publishers conduct daily and monthly polls of market participants in
order to estimate a representative market price transacted for natural
gas at a variety of geographical delivery areas. The published gas
indexes allow for managing a financial exposure to the gas index
price without transacting any physical natural gas. For example, July
gas at Chicago Citygate may be trading in the forward market for
US$5.00/MMBtu, and a financial buyer may enter a contract to pay
US$5.00 and receive the Chicago Citigate index price after it is
published at the beginning of July.

DEMAND SIDE DYNAMICS FOR NATURAL GAS
Most consumption of natural gas falls into four of the categories used
by the EIA: residential, commercial, industrial and electric generation. Residential and commercial use is primarily for heating, and
both sectors are characterised by a strong winter demand peak and
very flat demand in the summer. Industrial use has much less
seasonality, but about 10% does go toward heating demand in
winter. Electric generation burn peaks in the summer, when air
conditioning loads are the highest. In 2011, residential plus commercial users consumed 32%, power generation 31% and industrial users
28% of all gas consumed in the US.
Industrial use
Industrials use gas for space heating, process heat and also as a feedstock. As can be seen in Figure 2.1, industrial demand in the US
decreased dramatically from 1997, dropping by a total of almost 5.5
Bcf/day before bottoming in 2006. Since then, industrial use has
rallied by more than a Bcf per day, interrupted by the Great
Recession year of 2009.
Figure 2.2 deconstructs industry demand by sector; we find that,

from 1998 to 2006, there was declining use in every significant sector
except food and non-metallic minerals. The largest losses in use were
in chemicals manufacturing (down 2.59 Bcf/day), primary metals
(down 0.82 Bcf/day) and refining (down 0.43 Bcf/day). Within the
chemical sector, nitrogenous fertilisers alone accounted for almost
0.75 Bcf/day loss of demand over this time period due to production
moving offshore. Imports of anhydrous ammonia grew by 4.4 million
short tons, equating to 0.45 Bcf/day of domestic gas demand loss.
Since 2006, industrial use of gas has begun to grow again. Of
course, the deep recession between late 2008 and early 2010 created a
loss of demand of around 1.5 Bcf/day in 2009. However, growth of
industrial demand has started to accelerate due to low natural gas
prices, which looks to continue into the future, driven by a resurgence in the chemical and refining sectors. Domestic ammonia

production has been stepped up again, and a number of corporations
have announced plans to build new chemical plants to take advantage of the low energy prices in the US. There have even been
announcements of new metal-processing plants to be built,
expanded, or reopened. It appears likely that 2013 industrial
consumption will be at least 2 Bcf/day above the levels of 2006, and
growth should continue to be robust for a number of years as new
use facilities come online.
Power generation
Because power generation is a large and growing source of demand
for natural gas, an understanding of the power markets is critical in
anticipating future levels of gas demand. Increasing use of gas for
power generation has provided the largest increase of any sector.
Figure 2.3 shows monthly average gas burn for power generation
and the upward trend in demand since the early 2000s. Figure 2.4
shows that this steady growth in gas burn for generation continued
even through years of little or no growth in total power demand.
This trend is poised to continue as the phasing in of air pollution
standards for coal plants leads to continued coal plant retirements.
Figure 2.3 shows that monthly gas burn also comprises strong
seasonality of gas generation burn with the distinct summer “air
conditioning” demand peak and the much smaller winter heating
demand peak that has emerged.
Most of the growth in gas burn for power since the early 2000s has
come at the expense of decreasing coal-fired generation. Figure 2.5
shows the annual mix of generation sources for the 11-year period
ending in 2012. During this time, the percentage of generation from
nuclear plants and from sources other than coal, gas and nuclear
(which leaves hydroelectric, other renewables and liquid fuels) has
held roughly constant, so there has been an almost one-to-one tradeoff in loss of coal generation with gain in gas generation. Gas
generation has grown from 17.9% in 2002 to 30.4% of total US generation in 2012, while coal has fallen from 50.1% to 37.4% over that
time. We should note that 2012 was an exceptionally high year for
gas burn due to conditions that may not recur in the near future.
In fact, power generation provides one of the few demand sectors
that can significantly change the fuel mix based on short-term fuel
price levels and economics. During the period of cheap oil in the

1990s and early 2000s, fuel oil was sometimes economically competitive with natural gas, so during times of high gas prices there could
be an economic incentive to turn on oil-fired generation – which, in
turn, liberated gas for higher value heating use. With the advent of
oil prices near US$100+/bbl, natural gas has remained much less
expensive and oil use for generation has fallen from the already low
level of 2% of total generation in 2002 to 0.3% in 2012.

THE NORTH AMERICAN NATURAL GAS MARKET
Latterly, coal-to-gas substitution has become a key factor to watch
for understanding demand trends for natural gas. The relative costs
of generating power from coal and gas drive substitution economics.
To calculate the cost of generation, we must know how much coal or
gas it takes to generate a megawatt (MW) of power. The amount of
fuel required per unit of power generated is called the heat rate. For
actual generation plants, the heat rate will depend on a number of
factors – including type of equipment, generation level (% of
maximum capacity) and ambient air temperature. After estimating
the heat rate, fuel cost and variable operating and maintenance cost,
the marginal cost of power production can be calculated for a plant.
Many analysts construct “stack models”, in which plants are
stacked in order of their production costs, then the market’s marginal
cost of production can be found for a given level of net power
demand, and the amount of expected gas burn and coal burn can be
calculated. Of course, there are many additional details involved in
this process, including estimation of load served by nuclear and
renewable sources, forecast of power imports and exports to
connected regions, plant maintenance and forced outage rates, and
the influence of operational optimisations to minimise start costs. In
practice, stack models are difficult to calibrate for accurately forecasting future market prices, but they can be quite useful in more
qualitative analysis of market trends and behaviour.
Figure 2.6 tells of an interesting chapter in the natural gas demand
growth story. US power load growth accelerated in the mid-1990s at
the same time that uncertainties about market deregulation and
about future coal plant environmental regulations led to a reluctance
to build additional coal-fired generation. The market reacted by
beginning an unprecedented build of new gas-fired generation,
which can be seen by the huge increases in gas capacity as new plants
came online in 2002 and 2003. The build rate slowed but has
continued through the last decade. In addition to making more gasfired generation capacity available, the new and more efficient plants
have lowered the average heat rate of the available gas-fired generation fleet. The average heat rate of gas generation has dropped from
just over 10 MMBtu/MWh in 2001 to 8.15 MMBtu/MWh in 2011,
and the US continues to build new combined cycle gas turbines with
heat rates near 7 MMBtu/MWh.
The shift away from coal toward gas generation is set to continue,

with over 30 gigawatts (GW) of additional coal plant retirements
planned between 2013 and 2018. In that time period, combined cycle
gas generation capacity may grow by almost 60 MW if all planned
units are permitted and built.
Residential and commercial demand
While the residential and commercial (rescom) use of gas has not
displayed the growth seen in the generation sector, there are substantial year-to-year variations in total use. The largest driver of demand
variability in rescom use are winter temperatures, which influence the
amount of gas needed for home and commercial heating during the
cold months of the year. As can be seen in Figure 2.7, there has been
considerable variability in the weather-sensitive heating demand
months, but no obvious trend or much change in summer demand
levels since the early 2000s. This suggests that growth in the number of
consumers has been offset by conservation and heating efficiency
gains, resulting in very little (if any) net demand growth.
Exports
The US plans to begin exporting LNG from the Gulf Coast. Sabine
Pass LNG facilities target around early 2016 for beginning LNG
exports. With US gas prices likely to remain in the range of
US$4.00–6.00 MMBtu, landed prices to Europe would likely be in the
range of US$8.00–11.00 MMBtu. Export volumes are expected to

exports to over 3 Bcf/day by 2018, suggesting that the EIA’s
projected 2013–20 total production growth of about 5 Bcf/d (shown
in Figure 2.11) may be low compared to the likely demand growth.
SUPPLY SIDE CONSIDERATIONS
The US meets its gas needs primarily with domestic production and
imported gas from Canada. LNG imported by tanker from overseas
locations provides a third source of supply. Figure 2.8 shows historical monthly production since 1993. Production grew slowly in the
1990s and peaked in March of 2001. Production then began a series of
annual declines that led many to believe that domestic US gas supply
might be permanently headed in that direction. LNG imports were
seen as the solution to securing additional gas supply. In 2000, the US
had two operating LNG import facilities: Everett and Lake Charles.
Two additional existing facilities, Elba Island and Cove Point, mothballed in the early 1980s, were re-commissioned and began receiving
deliveries in 2001 and 2003, respectively. In addition, the Federal
Energy Regulatory Commission (FERC) granted authorisations for
several additional import terminals that were completed and
commissioned in 2008–11. However, most of these new facilities
have not yet seen heavy use due to the strong resurgence in domestic
production that began in 2007.
Shale gas
The driver of this reversal in fortune for natural gas production was
a combination of new technologies and higher natural gas prices,
which allowed shale gas to be produced economically in high quantities. Conventional gas production came largely from gas trapped in
sandstone formations with high porosity and permeability, allowing
the gas to flow through the formation to the wellbore. It had long
been recognised that natural gas was also trapped in many shale
formations, but shale is characterised by much lower porosity and
permeability that limits the movement of the trapped gas. Mitchell
Energy began to experiment with a combination of horizontal
drilling and hydraulic fracturing to produce gas from the north
Texas Barnett Shale. After Devon acquired Mitchell in 2002, the
Barnett drilling programme accelerated and, by 2007, the Barnett
Shale produced 1.1 Tcf of gas equivalents – making it the second36

largest producing field in the US (see Joel Parshall, 2008, “Barnett
Shale Showcases Tight-Gas Development”, JPT, September). After
this success in the Barnett, many shale fields began to contribute
significantly to US production, and Fayetteville, Haynesville,
Marcellus, Bakken and Eagle Ford all became well-known names in
the oil and gas E&P sector. Shale gas grew from less than 3% of US
gas production in 2003 to more than 40% at the beginning of 2013.
Figure 2.9 shows this growth in production from shale gas fields.
Figure 2.10 shows that the number of drilling rigs directed
towards natural gas production more than doubled from ~700 in
2003 to a peak of almost 1,600 near the beginning of the financial
crisis and recession of 2008–09. Then, in spite of the gas-directed rig
count plunging back to the 700–1,000 levels, natural gas production
continued to grow as shale gas production growth accelerated in
2010 and 2011.
The continued growth in production even with lower gas directed
rig counts can be attributed to a combination of factors, including the
shift of drilling towards horizontal shale wells, improvements in
drilling efficiency and growth in associated natural gas production.
From September 2008 to September 2010, the number of gas-directed
rigs fell from roughly 1,600 to 1,000; however, the number of hori-

zontal drilling rigs directed towards gas actually increased from
~500 to about 650 over the same period. In other words, horizontal
drilling grew from one-third of gas rigs to almost two-thirds by late
2010. The much higher average initial production rates from horizontal wells allowed continued production growth with lower rig
counts. At the same time, drillers were learning and improving the
efficiency of their shale-drilling operations, leading to shorter
drilling time and more wells drilled by each active rig, a trend which
continues.
The rapid deployment of oil-directed drilling rigs beginning in
July 2009 can be clearly seen in Figure 2.10. According to the EIA,
natural gas associated with oil was about one Bcf/day higher in 2012
than in 2010, thus adding to natural gas production growth. It should
also be noted that the distinction between drilling categorised as oildirected as compared to gas-directed is somewhat imprecise.
Additionally, new natural gas production lags drilling activity,
especially in the new shale production fields, because wells often
must wait for infrastructure to catch up with drilling – whereas oil
production can, if necessary, be moved by truck or rail. The only
economically feasible way to move natural gas production from the
wellhead is by pipeline. Therefore, new fields must wait for the
requisite gathering pipeline systems to be constructed to deliver gas
to users and to the long-haul pipeline system. In addition, wet or
sour gas production may need to wait for processing facilities that
remove liquids and impurities before the gas can be delivered to a
major pipeline.
Robust production growth plus the warm winter of 2011/2012 led
to a supply surplus, driving prices down to below US$2.00 for the
first time in years. Gas-directed rig counts plummeted to near 400
rigs, the lowest level in a decade, as many shale gas fields became
uneconomic at the low price levels.
In the long run (but hopefully before we are all dead), one would
expect that natural gas prices should gravitate towards a price level
that makes marginal production economic. However, limited transparency of drilling costs and uncertainties in well production
profiles and estimated ultimate recoveries (EUR) make estimating
production costs difficult. Also, costs and efficiencies change continually, making drilling economics a moving target. In addition, the
proportion of associated liquid hydrocarbons influences the overall
41
02 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:37 Page 42
COMMODITY INVESTING AND TRADING
economics as the liquids sell at a premium to natural gas.
Conventional wisdom recognises the Marcellus shale as the lowest
cost of the gas shales, with production costs below US$3.00/MMBtu
in the prime locations. With strong crude oil prices, gas-drilling
returns may have to compete with oil-drilling economics when
exploration and production budgets are decided.
Weather impacts on supply
Certain types of weather events can influence production as well as
demand. The clearly noticeable production drops in August and
September 2005 and September 2008 were caused by hurricanes in
the Gulf of Mexico, where there is substantial offshore gas production. Hurricanes Katrina and Rita were both Category 5 storms as
they crossed the production area in 2005, and hurricanes Gustav and
Ike were both Category 4 storms. Smaller hurricanes, and even tropical storms, may cause some disruption to supply as personnel are
evacuated from the storm path and some production platforms may
be shut-in as a precautionary measure. Rita and Katrina shut-in
almost 520 Bcf of production, and the 2008 storms caused a loss of
about 340 Bcf of production. Offshore gas production has been in
decline but remains above 4 Bcf per day. Because hurricanes need
very warm water temperatures to power them, the Gulf hurricane
season runs June–November, with August, September and October
being the most active months.
The production decline seen for February 2011 in Figure 2.11
resulted from very cold temperatures in Texas and nearby states. Gas
production declined from wells freezing off and from conditions that
hampered the ability of pumpers to maintain production. Severely
cold temperatures happen rarely enough in these production areas
that many wells do not have protection against cold temperatures,
allowing water vapour in the natural gas stream to freeze and
constrict flow from the wells. Thus, when unusually cold weather
invades southern and southwestern production areas, freeze-offs are
a danger to production.
Ethane rejection
NGLs, which are comprised of ethane, propane, butane and heavier
hydrocarbons, enhance production value when stripped from the
natural gas stream and sold separately. The stripping of wet gas,
42
02 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:37 Page 43
THE NORTH AMERICAN NATURAL GAS MARKET
carried out by fractionation facilities, may also be necessary to bring
the liquid content of the gas down to standards required by
pipelines. For example, 1.25 MMBtu/Mcf gas may yield around 0.12
bbl of liquids per Mcf. At an average liquids price of US$25.00/bbl,
the liquids alone are worth US$3.00/Mcf and may comprise nearly
half of the value of production.
The lowest value liquid in this stream, ethane, may fall below the
value received by leaving it in the delivered gas stream. In these
cases, the ethane can be rejected during the fractionation process and
effectively increases the net amount of delivered natural gas. That is,
when we say that ethane is rejected, we mean that it is left in the gas
stream with the methane. Ideally, economics will dictate the ethane
rejection decision; however, with the rapid growth of new gas
production in some regions, the infrastructure is sometimes not
sufficient to process all of the produced gas. The total amount of
ethane being extracted from the US gas stream had a heating equivalent value of about 3 Bcf/day of gas in late 2012, and the historical
levels of ethane extraction suggest that varying ethane rejection
could impact net gas deliverability by up to 0.5–1 Bcf/day.
STORAGE
There is a mismatch between highly seasonal demand as compared
to production which, in the absence of disruptions, trends more
slowly over the years. The large seasonal variability of demand
requires gas to be stored in the low-demand months and withdrawn
in times of high demand. There are over 400 natural gas storage facilities in the US to support this balancing need. Most use depleted gas
reservoirs as the storage space, but leached out underground salt
domes provide almost 8% of the storage capacity and another 8% is
provided by aquifer storage. Reservoirs take many months to fill and
so can be cycled only once a year, although there is usually some flexibility in scheduling the injections and more flexibility in the timing
of withdrawals. Salt domes require much less time to fill, perhaps
one month or less, and so can be cycled many times per year if there
is an economic opportunity to do so. During the 2010/2011 heating
season, a net amount of about 2,200 Bcf was withdrawn from US
storage and then about the same net amount injected during the
summer; however, gross injections plus withdrawals for the year ran
well above the annual net injections plus net withdrawals, showing
43
02 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:37 Page 44
COMMODITY INVESTING AND TRADING
that many short-term storage injections and withdrawals are made
to support the daily physical market balancing, as well as the annual
seasonal cycle of demand.
Gas storage nomenclature denotes working gas capacity as the
amount of storage gas that can be cycled in and out of storage facilities as part of normal operations. An amount of base gas must be
maintained in the storage facility at all times to maintain the integrity
of the facility. Base gas plus working gas added give the total storage
capacity. Most analysts of supply and demand are mainly interested
in watching the level of working gas in storage, as this represents the
gas available to withdraw for market needs.
As of early 2013, the EIA estimated that US facilities have the
ability to store 4,558 Bcf of working gas. However, the most working
gas actually in storage at any one time was 3,929 Bcf, in autumn 2012.
The EIA also calculates the “demonstrated peak working gas
capacity” by adding the non-coincident maximums for each facility
to get 4.24 Tcf, 94% of the design capacity. Latterly, additional
storage has been added at a rate of around 75 Bcf of working gas each
year. The maximum working gas capacity becomes quite relevant to
the market in years such as 2012, when the market was oversupplied
and excess production needed to find a home. In spring and early
summer 2012, prices collapsed on fears that storage might fill
completely, but low prices solved the problem as power producers
turned off coal plants and turned on combined cycle gas turbine
(CCGT) plants to burn the inexpensive gas.
Analysts speculate on what minimum amount of working gas the
market “requires” at the end of the injection season. As can be seen in
Figure 2.12, end-of-season fills since the early 2000s have ranged
from just under 3.2 Tcf to just over 3.9 Tcf. Because of the growth in
use, many believe that the market will now want to be near the high
end of this range to ensure winter reliability of supply.
Each Thursday, the EIA releases a weekly report giving their estimate of the amount working gas in US storage as of the previous
week. This widely anticipated publication gives the single most
important short-term data point about the current supply and
demand balance, and often incites a strong price response from the
natural gas markets. Because of the high importance of the reported
number, fundamental analysts labour daily to forecast it. The EIA’s
number itself is based on a statistical model that they use to extrapo44

late from their population of storage survey respondents to a total US
storage amount, and so has some level of uncertainty itself. This
number represents the net injection or withdrawal summed over all
US storage facilities. Net injections typically begin in late March or
early April, making March the last month of net injections and April
the first month of the year with net withdrawals, except in extreme
conditions such as the warm March of 2012, which left that month
with net injections. During autumn, November is usually the first
month to see weekly withdrawals, although there have been net
withdrawals as early as the last week of October or as late as the first
week of December. In 2006, summer gas demand for power generation was sufficiently strong and production low enough that there
were net withdrawal weeks in late July and early August.
Because of this seasonality of injections and withdrawals, the
natural gas year is divided into the summer (injection) months of
April–October, and the winter (withdrawal) months of November–
March. This seasonality of storage manifests itself in the gas markets
as well. The volatility of the price spread between the October and
November contracts, and the volatility of the price spread between the
March and April futures, are often the highest of all the sequential
month spreads. Also, the term structure of options volatility typically
has local maxima for options on the October and March contracts.

GEOGRAPHY OF PRODUCTION AND DEMAND
A large portion of the US gas supply has come from the Gulf Coast
and mid-continent. Texas has the largest gas production at about 20
Bcf/day. Neighbouring Louisiana produces ~8 Bcf/day, and gas
from the Gulf of Mexico Federal Offshore areas comes ashore to
pipelines in Texas, Louisiana and Alabama, and adds another ~4
Bcf/day of supply, although this is less than half of the offshore
supply levels seen in the early 1990s. Additional supply comes from
Oklahoma (~6 Bcf/day) and Arkansas (~3 Bcf/day). There are two
other large supply areas outside of the Gulf coast/mid-continent.
The Rocky Mountain states of New Mexico, Colorado, Utah and
Wyoming combine to produce about 15 Bcf/day of gas, and
Marcellus Shale and other production in Pennsylvania and nearby
states adds about 12 Bcf/day.
Texas, Louisiana and Oklahoma also consume large amounts of gas
for industrial use and power generation. Other demand centres are
the highly populated states of the northeastern US, the midwestern
states and California; Florida and the southeastern states use significant gas generation to serve summer cooling load. Table 2.11 shows
production and estimated net exports for the main supply areas and
demand and estimated net imports for the top demand areas.
An extensive pipeline network provides for the movement of gas
from the supply to the demand areas. Many pipelines have been
built from the traditional Gulf Coast and mid-continent supply areas.
Multiple pipelines, including Texas Eastern Transmission Company
(TETCO), Transcontinental (Transco) and Tennessee Gas Pipeline
Company were built to transport gas from the Gulf states to demand
areas in the northeast. Some of these pipes are now backhauling gas
from the shale fields of the northeast back towards the Gulf. Florida
Gas Transmission and Sonat carry gas to Florida. Northern Natural
Gas, Panhandle Eastern Pipeline Company, ANR and Natural Gas
Pipeline Company of America (NGPL) deliver gas to the midwest. El
Paso Natural Gas and Transwestern Pipeline take gas west to the
California market.
The Kern River pipeline to California and the more recently built
Rockies Express Pipeline, which can move gas east to Ohio, provide
two primary outlets for gas produced in the Northern Rockies, while
Transwestern Pipeline can take San Juan Basin gas from Northern
New Mexico and southern Colorado to Arizona and California.

PRICE DYNAMICS OF GAS FUTURES
Figure 2.13 presents historical natural gas prices since 2002, and
relates how fundamental drivers of supply and demand have translated into changes of price regime. The figure shows the average
price of the front 12 futures months in order to remove seasonality
from the prices. We have reviewed earlier the most important factors
influencing the supply/demand balance which, in turn, creates pressure on natural gas prices.
Let us look at some of the fundamental drivers of price levels. On
the demand side, there is:
weather (winter heating, summer cooling loads);
al price competition; and

influencing weather events are noted on the figure. A cold 2002/03
winter pushed gas storage down to very low levels and prices up
above US$6.00, before a mild summer in 2003 helped storage levels
recover, and gas sold back down to below US$5.00. Similarly, an
extremely cold January in 2008 started gas on its run towards prices
well over US$10.00. The recession of 2008 destroyed industrial
demand and sent gas prices back down, and this trend was exacerbated by mild summer weather in 2008 that further decreased gas
burn for power generation.
Some time periods, however, show gas prices trending generally
upward while storage also builds, such as March 2004–December
2004. For most of 2006 and 2007, storage levels trended, on average,
lower, but prices gradually moved lower as well. The same happened
mid-2009 to end-2010. Referring back to Figures 2.8 and 2.11, we see
that production was on a downwards trend from 2001 to 2005, so
prices moved higher to drive out demand. Perhaps the storage builds
in 2004 were not taken as a sign of structural surplus but a temporary
respite from the tightening supply balances. In contrast, production
began its spectacular rebound in 2006, and the market took several
years to understand and digest the implications of the shale gas revolution. Market prices were adjusting downward even during times
when the storage surplus was reverting to near historical levels.
Figure 2.14 shows historical prices for the prompt (ie, front)
natural gas contract. The figure also shows a measure of the
contango (slope) of the futures curve, calculated here as the price of
the 14th contract less the price of the second contract – in other
words, the one-year contango of the futures curve starting at the
second to expire contract. Clearly, the level of curve contango has a
strong inverse relationship to the front month price level for most of
the 11 years of price history shown.
Because the contango of the price curve is quite volatile, traders are
attracted to trades sensitive to changes in the slope of the price curve.
Many trading strategies attempt to profit from changes in calendar
spreads by taking spread positions, shorting one month and going
long a different month. Because of the seasonal nature of gas use and
storage, certain calendar spreads tend to have more trading interest
and thus higher liquidity. Many of the favourite spreads involve the
key storage season months of October, March and April. The
March/April spread, sometimes referred to as the “widow maker”,
52
02 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:37 Page 53
THE NORTH AMERICAN NATURAL GAS MARKET
trades actively, as do the April/October and October/January
spreads. Two other favourites are the January/March and January/
April spreads, which have high sensitivity to winter price seasonality.
In addition to these seasonal spread favourites, the prompt/
prompt+1 month spread is active, as is the second/third futures
month spread, as index fund managers and other market participants
are active in rolling forward their nearby month positions.
Figure 2.15 shows the evolution of the front 60 months of the
natural gas futures curve. Historical curves for each year, 2002–2013,
are shown as of late March of each year, when the April contract is
prompt. A number of interesting features can be seen from this
evolution. The front of the curve tends to lead in most price movements. Therefore, the curve will often go into backwardation when
prices move sharply higher, and contango steepens when prices
move rapidly lower. The winter to summer month spreads clearly
went higher during the high gas price environment of 2005–2008, but
collapsed to very low levels in 2012 and 2013.
CONCLUSION: KEY ISSUES FOR THE COMING DECADE
Since the early 2000s, the natural gas market has moved from a
period of declining production and use into a new period of production growth so rapid that it managed to push prices back below
US$3.00, a price level that few in 2006 or 2007 ever expected to see
again. These lower prices have encouraged drillers to concentrate
more on crude oil production and less on dry gas, and at the same
time engendered a renaissance of gas-intensive industrial demand.
Increases in gas demand for industrial use and power generation
should require additional gas production, and potential exports of
LNG will accelerate demand from around 2016. At what point in
time will growth in associated gas production fail to keep up with
demand growth, requiring prices to rise to a level that will encourage
more drilling directed towards dry gas? How long will drilling efficiency gains continue to push down production costs, and will
production costs begin to rise dramatically when the best shale
prospects have been produced? Even with renewed gas-directed
drilling, will production growth manage to keep up with the large
price-induced demand growth that we are witnessing?
All of these interesting questions will require constant reevaluation over the coming years.

GLOBAL LNG
Rita D'Ecclesia
Sapienza University of Rome
Global LNG flows reached over 200 MMT in 2012, the equivalent of
almost 10 Tcf of gas or about 8% of world gas production. This panel will
discuss major exporters and importers and possible trends going forward.
Exports
By 2012, LNG exports represented about 30% of international gas flows.
Global LNG exports grew from 117 MMT in 2005 to 203 MMT by 2012,
an average annual increase of 10%. Table 2.3 shows the LNG exports for
the 10 largest exporters since 2005 including Canada scheduled to be a
major player by 2020.
The biggest LNG exporters in 2005 were Indonesia (17%), Malaysia
(15%), Algeria (14%) and Qatar (14%), accounting for 60% of world
exports. By 2012, the balance had shifted and four countries – Qatar
(39%), Malaysia (13%), Australia (11%) and Indonesia (10%) – accounted
for 73% of the total exports, with Algeria having heavily reduced its share.
During this period LNG exports grew by 56 MMT. In terms of
geographic distribution the Middle East was the fastest growing exporter,
growing from 38 MMT (28% of total) in 2005 to 85 MMT (43% of total) in
2012, while the Atlantic Basin reduced its exports from 44 MMT in 2005
to 37 MMT in 2012.
Exports are tied to the liquefaction capacity of each country, therefore
we need to look at the existing plants and those planned for the next
decade. In Table 2.4, the evolution of liquefaction capacity between 2000
and 2012, and an estimate for 2020, is provided. The list of exporters with
more than 10 million metric tonne per annum (MMTPA) of liquefaction
capacity is short and rapidly changing. There are 20 countries exporting
LNG and five major re-exporters (Belgium, Brazil, Mexico, Spain and the
US). Liquefaction capacity utilisation around the world averages 90%, and
so its growth is critical to expanding volumes, whereas global utilisation of
regasification is only 35%.
In 2001, the US was expected to become a major importer of LNG, but
by 2012 a resurgence in US gas production lead to the prospect of the US
becoming a major exporter once liquefaction trains become operational,
expected to begin around 2016.
Because of the high infrastructure costs of creating and delivering LNG,
most projects require long-term contracts that lock in the destination of
LNG produced. An estimated 25% of these flows are now short-term
contracts (less than four years in duration), and an increasing amount of
LNG flows are in the hands of international oil and gas companies (IOCs
– see Table 2.4) with more destination flexibility.
From 2008 to 2012, IOCs increased their share of export capacity by 45

billion cubic meters per annum (bcm/a) from 85 to 130 bcm/a, led by
Shell, Exxon Mobil, Total, ConocoPhillips, Woodside and Chevron.
National oil and gas companies (NOCs) increased by 74 bcm/a, from 137
to 211 bcm/a. Trading houses, LNG importers, financial institutions and
local companies represent the balance, 33 bcm/a in 2008 and 48 bcm/a
by 2012. NOCs have an obligation to satisfy domestic demand, therefore
Russia, Nigeria and Indonesia are increasingly focused on the price gap
between their domestic market and export prices. In general, IOCs are
more responsive to market conditions, and bring advantages in terms of
integrated project development. European utilities with considerable LNG
strategies include GDF-Suez, EdF, E.ON and RWE.
In 2012, Qatar dominated global export capacity with a 39% market
share and 84 MMTPA of liquefaction (see Table 2.5). The other Middle
East exporters, including Abu Dhabi, Oman and Yemen, have no reported
plans to expand their liquefaction capacities. Qatar is a true swing
exporter and, in the period 2008–12, sent on average 35% to Europe, 5%
to the Americas and the rest to Asia (of which 33% was to Japan, 25% to
each of India and South Korea, 10% to Taiwan and 7% to China). Asian
demand growth is impressive (see Table 2.6). China has grown from
nothing in 2005 to 5 MMT in 2012, India from 6 to 10 MMT, Japan from 8
to 16 MMT and Taiwan from 1 to 6 MMT. South Korea is the only stagnant
Asian importer, with 9 MMT in 2005 and 11 MMT in 2012. Most of the
LNG from Abu Dhabi, Oman and Yemen flows to Asia.
The Pacific Basin liquefaction capacity stands at 92 MMTPA, representing 38% of the world total. It is expected to increase by 2020 as many
large Australian and Canadian projects come online, and Australia is
expected to tie with Qatar’s liquefaction capacity. Indonesia has been
experiencing domestic production outages, and is therefore planning to
expand its liquefaction capacity to send out 40% of production to the
domestic market. In addition, adding new liquefaction capacity in 2014,
Indonesia is converting two ageing liquefaction plants to regasification.
Malaysia has had a series of outages on liquefaction maintenance and has
minor plans for floating liquefaction in the future.
Australia and Canada are positioned to be key exporters in this basin. In
the period 2005–12, Australia added 24 of the 26 MMTPA Pacific Basin
liquefaction increase. According to planned new liquefaction plants,
Australia will increase its capacity by 60 MMTPA, and Canada is expected
to build 17 MMTPA of liquefaction capacity by 2020, estimated as 50% of
the 34 MMT of filed projects.
The major Atlantic Basin exporters hold 23% of liquefaction capacity.
From 2005, Algerian capacity has remained unchanged at 19 MMTPA,
still recovering from the 2004 explosion at Skikda that kept capacity
offline in the 2008–12 period. New capacity additions for Algeria have
been quoted at US$1,000/MT capital costs. Egypt started as an exporter in
2004 and has 12 MMTPA of capacity. Its economic growth has created
more domestic demand, and it is planning to build regas capacity. By

many estimates, Egypt will not be an exporter by 2020. Its utilisation of
liquefaction has dropped from almost 90% in 2008 to 40% in 2012 (see
Table 2.11). Nigeria holds 22 MMTPA of liquefaction, more than doubling
since 2000, but suffers considerably from political unrest and infrastructure construction delays. Despite having the greatest gas capacity in the
Atlantic Basin, it continues to struggle to perform. The US is expected to
operate 85 MMT of liquefaction capacity by 2020 out of the 135 MMT of
filed projects, according to the author’s estimates.
Importers and import growth
Import demand is relatively simple to analyse in the LNG market, given
the different regional demand drivers. Asia depends heavily on oil, and
LNG increasingly flows to the industrial complexes on the southern coast
of China. China’s natural gas assets are in the Northwest, and while the
trans-China gas pipelines will inevitably be built, LNG is at least the short-

term supply choice. Coastal India is another big importer, where GDP is
crimped by a lack of energy, and rolling brown-outs are common.
Asia more than doubled imports in the period 2005–12, with Indonesia
and Taiwan starting to import in 2005, with Japan, China and South Korea
also increasing their volumes. Europe and the Americas reduced their
LNG imports in 2010–12, despite increasing between 2005 and 2010
(Table 2.6), due to factors such as price, the economic downturn and
increasing US domestic production.
Asia is the largest importing region, with almost 65% of total world
imports. In 2008–12, Asia imported an average of 136 MMT (63% of
world total imports). Of these, 55% was delivered to Japan, 22% to South
Korea, 6% to China and the remaining 17% to India, Taiwan and
Indonesia. Imports in Asia have staged a recovery after a contraction in
2009 (–7%, see Table 2.7).
European imports increased by 70% during 2005–12. In 2012, they
accounted for 21% of global imports. The largest importer is Spain (31% in
2012), followed by France (15%), the UK (21%), Turkey (11%), Italy

(10%), Belgium (6%) and the Netherlands (1%). These six countries
account for the lion’s share of demand (96%).
Imports by the Americas accounted for an average 17 MMT over 2005–
12, and in 2012 were a mere 7% of world LNG imports. The US
accounted for 44% of the volume followed by Mexico (19%), Argentina
and Chile (9% each), and 6% for Brazil and Canada.
Two countries in the Middle East (Kuwait and Dubai) started to import
LNG in 2009 and in 2012 were an insignificant 1% of global imports.
Imports of LNG are linked to the regasification capacity of the various
importing countries (see Table 2.8). In 2012, there were 93 LNG regasification terminals operating in the world including 11 floating facilities.
There are two possibilities for significant regasification capacity growth
around the world. Both China and India have considerable plans to
expand LNG imports. The GIIGNL 2012 Annual Report lists eight projects
under development in China that are expected to add some 15 MMT of
regas capacity. This would double Chinese import capacity. By 2020,
China could be importing as much as South Korea. India similarly lists
12.5 MMT of capacity under construction, likely to continue to be
hampered by logistical issues, and also lists a variety of terminal and distribution projects. This would more than double Indian import capacity into
the early 2020s.
Regasification in Europe is mainly concentrated in the seven largest
European importers which have 82 of the total 88 MMTPA of regasification capacity. The utilisation rates swing depending on the LNG price. For
example, Spain imported 22 MMT in 2008 and only 15 MMT in 2012. The
flexibility of imports in Europe is a reflection of its market maturity and efficiency. The LNG demand in Europe has been growing at a fast pace over
2005–10, with an annual average growth of 19% to 2011, and declined

heavily in 2012 (–25%, partly due to relative price and partly economy
shrinkage). The large reduction of LNG demand is in line with the heavy
reduction of natural gas demand in 2011–12 in Europe. In the period
2005–08, virtually every European country, from Lithuania to Ireland,
added regas capacity.
In the US during 2005–08, a lot of regas capacity was built, but subsequently was not needed, so US utilisation rates are abysmal.
Regasification global usage is only 35%, but capacity utilisation varies
widely by region. Regas capacity can provide flexibility and security of
supply. Utilisation rates change as capacity is added and as other energy
flows dictate. For example, between Spain and France energy may flow as
gas or be wheeled as electricity.
Table 2.9 lists regasification capacity utilisation rates. Italy’s data is difficult to follow, with listed additions apparently running earlier than official
openings. India suffers from the same problem. Russia and China do run at
excess of nameplate capacity. Taiwan’s import data is suspect. All figures
come from GIIGNL.

LNG supply chain
The cost of gas is critical to the analysis of future export availabilities, especially for US shale gas. The cost of building liquefaction has risen
dramatically:
❏ the variable costs of liquefaction in the US are approximately
US$2/MMBtu;
❏ transatlantic freight is approximately US$1/MMBtu; and
❏ regas costs are US$0.50/MMBtu.
This means a built-in supply cost which must be added to the natural gas
price (Henry Hub) of US$3.50/MMBtu for gas landed into Europe. This
natural gas chapter estimates the price at which we will continue to
expand US shale gas at US$4.00–5.00/MMBtu leaving us with a landed
Europe price of US$7.50–8.50/MMBtu. Notwithstanding this high price,
we expect to see a continued healthy European demand, especially if GDP
growth can recover.
Assuming Japan has an incremental freight cost of US$2/MMBtu the
natural gas price for Asia may reach US$10.50/MMBtu. The liquefaction
cost in Canada, after the building of the planned liquefaction plants, is
expected to be close to US$1.70/MMBtu, and these volumes are directed
to Japan.
Terminal expansion is lowering costs along with expanding fleet and
vessel size. The global fleet is 378 vessels and 54,000,000 m3, including
floating storage and regasification units (FSRUs). Only two vessels were
added to the fleet in 2012, compared to 16 in 2011, three ships were
scrapped and one was converted to an FSRU. More than 40 vessels in the
fleet have been used for over 30 years and more than 250 vessels are
under 10 years old.
62
02 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:37 Page 63
THE NORTH AMERICAN NATURAL GAS MARKET
The order book was 78 vessels at the end of 2012 and 27 new orders
were added in the year, of which 23 were LNG carriers ranging from
150,000–172,000 m3, two FSRUs, one regasification vessel (RV) and one
floating liquefied natural gas (FLNG) carrier (210,000 m3). ICIS Heren has
forecasted that additional expansion is needed for the fleet in order to
retire older ships in 2015–20.
What may be more important for estimating future shipping flows is the
ever-increasing share of flows to the Pacific basin, rather than the Atlantic
basin, lengthening tonne miles. The future growth of European demand,
on the other hand, depends mostly on building storage and distribution
assets, where environmental and other compliance issues will be considerably more expensive than in emerging or frontier markets. Concerns
over emissions seem to be curtailing European demand for LNG and
compressed natural gas (CNG) as a truck fuel.
Future LNG flow considerations
Liquefaction plant build costs in the early 2000s (such as Egypt’s US$250–
350/MMTPA and Oman’s US$200/MMTPA) were comparatively low.
Qatar RasGas II and III build costs were around US$350/MMTPA, while
Qatargas IV was close to US$750. Australian Pluto was estimated at
US$800 and the Russian Sakhalin capacity got deferred on an estimated
US$1,000. Geography, climate and political risks drive construction
costs. An ever-increasing amount of gas trying to come to market from
emerging countries (Equatorial Guinea, Yemen, Peru, Angola, PNG, Libya
and Iran) will not help lower costs of future liquefaction capacity addition.
This will make it increasingly easier for an IOC to get involved, compared
to an NOC.
More generally, domestic gas demand is growing in many producing
countries – for generating power and water, fuels and petrochemical
production, as well as reinjection to oilfields.
In terms of major exporters, we note that Qatar, who have paused liquefaction at current levels, actually have approvals in place to expand
liquefaction up to 105 MMT. This represents an opportunity. Nigeria still
has considerable waste between gas field and liquefaction, and an uncertain future for further developing gas pipelines within Africa. The US has a
major opportunity to capture export market share, but energy exports have
no great historical precedent within the world’s largest energy consumer.
Russia will inevitably add more LNG capacity for Asia.
Europe has experienced a reduction in natural gas production since
2000, from 232 bcm in 2000 to 150 bcm in 2012 (see Table 2.9). The
demand for natural gas reached a high of over 500 bcm in 2010, but by
2012 was back near the 2000 level of 440 bcm. Russian natural gas
pipeline exports to Europe have declined since 2000 bringing an increase
in other import demand from 14.5 bcm in 2000 to 108 bcm by 2012. This
equates to a European LNG demand of 80 MMT in 2012.

A Day in the Life of Commodity
Weather
Jose Marquez
Whiteside Energy
This chapter will offer insight into the role of a commodity meteorologist and how they aid our understanding of risk within commodity
markets. Primary sources of information, methods of interpretation
and strategy considerations are given from the perspective of an
energy trading firm. Weather linkages in other commodity markets
are also briefly discussed.
Weather drives daily volatility demand for natural gas. Weather
influences residential, commercial and electrical power end users,
natural gas is burned in the winter for heating and electrical generation requirements in summer. Regional demand differences and
seasonality ultimately affects natural gas futures pricing and
regional basis hubs. In natural gas markets, cold weather can force
peak day demand events where price-induced curtailments may
occur to non-temperature sensitive clients (ie, reduction of industrial
load) in order to ensure that needed gas is available to residential and
commercial consumers. Residential and commercial sectors requirements peak during the heating season, and gas must be stored to
meet the winter demand.
Weather is a constant source of short term volatility in natural gas
demand and price expectations. Therefore, a solid understanding of
the relationship between weather and natural-gas fundamentals is
imperative.

COMMODITY INVESTING AND TRADING
WEATHER DATA BASICS
Meteorologists working for commodity trading firms have long been
utilised in agriculture markets, where extreme weather conditions
affect diverse crops throughout the year. The US National Weather
Service (NWS) and several weather consulting firms provided
weather information and forecasts for 1–5 and 6–10 day periods.
Meteorologists then enhanced this information through further
interpretation and acted as a quality control for the weather forecasts
provided by these external sources. In the early 1990s with the deregulation of natural gas, Enron was the first energy merchant to utilise
meteorologists on staff to expedite and maximise the accuracy of
weather forecasts. The company understood the significant correlation between temperature and natural gas demand, and that being
ahead of the pack at incorporating incoming temperature changes
would help maximise profits on their large natural gas portfolio. For
example, buying or selling natural gas molecules ahead of others
gave the ability to profit from expected increase or decrease in
demand, which then moves price on a regional or national basis. Of
course, such methods to create a trading edge do not last forever.
Soon, many other energy trading firms maintained their own staffs
of in-house meteorologists. At one point, Enron had a team of six
people providing weather information to the trading desks.
The main daily source of weather information for everyone across
the globe comes from global weather models. Some models provide
forecasts up to 10 days, others up to 16 days. In a nutshell, a global
weather model is a sophisticated mathematical model that uses a set
of equations with diverse parameterisations that represent the Earth
and atmosphere. Horizontally and vertically, the Earth’s surface and
the atmosphere is divided into grids or pixels that interact with each
neighbouring point, ultimately allowing calculation of a forecast for
the future state of the atmosphere. The resulting forecast may step
through time, starting with three-hour increments increasing to 12hour time steps after 192 hours. The size of the geographic and
temporal grids are tuned in order to optimise the balance between
the number of required computations and the grid resolution, since
more calculations are required using the higher resolution grid
compared to the lower resolution grid. As an example, the grid size
or pixel may vary from 35-kilometre spacing up to 70-kilometre
spacing for forecast periods after 192 hours (8 days).
66
03 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:44 Page 67
A DAY IN THE LIFE OF COMMODITY WEATHER
Meteorological and oceanographic data to initialise the models
come from across the globe: from air and land weather recording
stations, weather satellites and commercial and military pilot
reports. This immense dataset is gathered, assimilated and fed into
various global weather models. An initial condition or initialisation
defines the beginning state of the earth–atmosphere system, before
forecasts with a defined time stamp are calculated by the models. As
you can imagine, the amount of data and the computational power
required to run these models are immense, and to truly obtain an
adequate global initial condition requires full access to global data
(some data could be considered confidential). Consequently,
specialised government agencies or research centres with special
international agreements for data sharing are the only entities
capable of producing a meaningful and skillful global forecast.
Therefore, meteorologists across the world obtain their daily
temperature and weather changes from global weather models
produced by various institutions. In the energy industry, the main
models observed and analysed are the American Model (GFS), the
European Model (ECMWF) and the Canadian Model (GEM). In
addition, and to a lesser extent, there is the NOGAPS (US Navy) and
short-range models such as the NAM (up to 84-hour forecasts). The
American model is run by the US National Weather Service's
National Center for Environmental Prediction, in Washington DC,
the European model is run by the European Centre for MediumRange Weather Forecasts, located at Reading, UK, and the Canadian
Model is run by Environment Canada (Canada’s National Weather
Service).
The US National Weather Service provides daily forecasts for the 1–
5, 6–10 and 8–14 day periods. The information comes in data output or
graphical format.
A DAY IN THE LIFE
Early in the morning, multiple weather sources release information
which could be utilised by the markets. The changes on weather
information and data are compared to the previous trading day
determining upcoming changes in natural gas demand and setting
the tone for traders early in the morning. Traders know that colder
than normal conditions in the highest population areas of the US,
mainly East of the Rockies in the winter means higher demand
67
03 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:44 Page 68
COMMODITY INVESTING AND TRADING
for the US as a whole. In summer months, warmer than normal
temperatures in the East, especially Texas and Southeastern US,
means more demand for air conditioning, of which a large
percentage is generated by natural gas-fired power plants.
Meteorologists on staff do not influence the market with their
information or have an influence on Nymex pricing. Their information is kept in-house. On the other hand, weather information and
forecasts come from multiple sources, including global weather
models which have a broad dissemination across markets. Thus,
large changes to the forecasts can create a tangible reaction in the
energy markets.
Meteorologists have their own language to forecast or explain
weather patterns and/or phenomena. They talk in terms of geopotential heights, vorticity and jet streams to mention a few. Energy
traders talk in terms of Heating/Cooling Degree Days (HDDs/
CDDs), increase/decrease demand, confidence level and risks.
Therefore, the most important job of the in-house meteorologist is to
"translate" the meteorology language into an energy trader's
language. They link the language of science to trading. The meteorologist on staff will gather all relevant information available from
multiple sources and streamline it in a way that is easily accessible
and understood by the trading desks. The meteorologist could come
with the following checklist: How is the weather pattern evolving for
the 6–10 and 11–15 day periods? What is my confidence level in the
weather pattern? What is the risk of the forecasts to change directionally and temporally? The in-house meteorologist gives a sense of
confidence level for the existing forecast. If the staff meteorologist
feels that the current forecast may change then forecasting how that
change is likely to occur, in timing and direction, becomes critical.
First, the meteorologist on staff has their own view of the weather
pattern for the 6–10 and 11–15 day periods. When all the moving
parts are in agreement, for example when diverse global weather
models forecasts are aligned, the job for the in-house meteorologist is
usually uneventful. However, when the in-house meteorologist is in
disagreement with the diverse global model’s output, the situation
can be quite challenging.
Most of the time, the divergence in forecasts starts when global
weather models are differing in their output. For example, the
European model may be showing a cold wave in the Midwest while
68
03 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:44 Page 69
A DAY IN THE LIFE OF COMMODITY WEATHER
the American model does not show it for the same time period. So,
there is no middle ground here and a forecast must be made. Does
the Midwest have a cold event or not? Therefore, the in-house
meteorologist has to react with a highly accurate, timely response
and be prepared to accommodate many information requests from
traders.
An important process after having a forecast view of the incoming
weather pattern is anticipating how or when the forecasts from
various sources may change. This task is called "forecast the forecast". Overall, agreement or disagreement with the forecast's output
from various sources serves as a confidence level barometer for
traders. Situations arise when the Nymex price moves strongly due
to forecasts of impending cold or warm events, and traders can put
immense pressure onto the in-house meteorologist to either change
the internal forecast or to precisely time when the forecasts will
change. Therefore, it is the meteorologist’s job to make such information both accessible and easy to understand, and to be clear and
concise about the risks from a challenging forecast.
Following Keynes’ advice that “Wordly wisdom teaches that it is
better for the reputation to fail conventionally than to succeed unconventionally”, the easiest way out is to agree with the general weather
view of the markets, and when the pattern “surprisingly” changes,
then point to the fact that global weather models were wrong. To
provide true value to the firm, however, the meteorologist must
make the best possible assessment of forecasting the forecast revision
and communicate that opinion along with the relevant risks to the
trading desks. The meteorologist should not get overly bogged
down in details but focus on the importance of getting the weather
pattern right first, and then worry about the details. Simpler is better.
After the early morning weather operations are finalised, several
weather updates will arrive during regular trading hours. As the
numerical models update, any significant change in the weather
pattern compared to early morning weather information could cause
price volatility. The NAM is the first one to update, although this
weather model only provides forecasts up to 3.5 days ahead. The
GFS is the first global weather model to update the 16-day forecasts.
The GFS is immediately followed by its ensembles, a package of forecasts that show the level of stability or instability of the current
solution. Then, the ECMWF updates after the American models are
69
03 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:44 Page 70
COMMODITY INVESTING AND TRADING
done. The whole updating process of new weather information
consumes the last three hours of the regular Nymex trading day.
TROPICAL WEATHER
There is a seasonal weather system that creates quite volatile price
action during the summer months: hurricanes. The hurricane season
runs from June 1 until November 30 in the Atlantic Basin. The main
threat area is the Gulf of Mexico, specifically from Mobile to just
north of Corpus Christi. Historically, close to 10% of total gas
production in the US could be impacted. The National Hurricane
Center (NHC), is the official entity responsible for issuing tropical
forecasts, watches and warnings.
NHC establishes a tropical cyclone as an organized system of
clouds and thunderstorms with a low level circulation rotating anticlockwise in the Northern Hemisphere. Tropical cyclones develop
over tropical or subtropical waters. They are classified as follows:
❏ Tropical Depression: Maximum sustained winds of 33 knots or
less;
❏ Tropical Storm: Maximum sustained winds between 34 to 63
knots. At this level, tropical cyclones are named; and
❏ Hurricane: Maximum sustained winds greater than 64 knots.
A hurricane’s exact centre location can easily be identifiable via
satellite imagery because of the development of an eye. In addition, a
hurricane wind scale called the Saffir–Simpson is used to classify
hurricanes into five categories depending on their wind intensity.
Category 1 hurricanes are dangerous and create some damage, while
category 5 hurricanes are monster storms that create catastrophic
damage. A storm is classified as a major hurricane when it reaches
category 3 or higher. In terms of the energy markets, the biggest
concern is when the hurricane becomes a major hurricane. At this
level, structural damage to energy infrastructure may occur both
offshore and onshore. Rigs and platforms can be destroyed and
severe damage may be inflicted on onshore refineries. Underwater
pipelines can also sustain damage due to heavy wave activity.
The NHC naturally has human safety as its primary objective, and
has been designated at the one official source of forecasts in order to
reduce possible confusion during hurricane events. History has
70
03 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:44 Page 71
A DAY IN THE LIFE OF COMMODITY WEATHER
shown that conflicting forecasts and "hype" from different media
outlets creates public confusion as well as potentially causing confusion in the energy markets. Imagine if there were several scientific
and media venues with different forecasts and weather/hurricane
model solutions showing landfall of specific hurricane ranging from
North Carolina to Tampico, Mexico. NHC is the liaison for all the
data gathering, scientific streamlining, government safety planning
and coordination, and dissemination of information to keep the
public alert and informed. When a tropical cyclone develops, they
send standard advisories every six hours, at 0300, 0900, 1500 and
2100 UTC, that include up to five days of forecast information. When
the tropical cyclone reaches a level of tropical storm or hurricane and
may be impacting land in the next 48 hours, watches and warnings
may begin to be issued, and intermediate advisories are released
every three hours between the main advisories after a watch and/or
warning has been issued.
Imagine such a large system being modelled mathematically,
trying to represent the entire structure and energy of the tropical
system. That is what global weather and hurricane models try to do.
As would be expected due to limited numerical capacity and
inherent model limitations, different models will show somewhat
different forecasts and, even worse, may show quite different forecast tracks for the storm. Global models may start by showing a
tropical system developing on day 16 off of the West Coast of Africa,
and Nymex price action may start to be influenced by the forecast. In
this scenario, three basic questions should be asked: Is the tropical
system going to develop into a hurricane? Will it be a threat to the
Gulf of Mexico? Most importantly, is it likely to grow into a major
hurricane that can damage infrastructure?
Therefore, from the NHC advisories and the constant flow of
updated hurricane output solutions from the models, the markets
become quite jittery, reacting to the diverse information as it is
revealed. If all models show the hurricane moving to the open waters
of the North Atlantic, the market will see that as a 0% chance of
impacting production. However, if one of the global or hurricane
models shows the hurricane moving into the Gulf, there is a chance
of a market-moving event which will be reflected in the price
action.
The in-house met has to constantly monitor all the information,
71
03 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:44 Page 72
COMMODITY INVESTING AND TRADING
analyse all the forecasts available and, of course, forecast the forecast
of the official tropical NHC advisory. The time between a tropical
cyclone developing off the coast of Africa and reaching the Gulf of
Mexico can take nearly ten days. High volatility of energy prices
comes packaged with these systems and persists over the lifetime of
these tropical cyclones.
OTHER WEATHER IMPACTS
Weather updates during regular trading hours provide energy
traders with significant demand change expectations for North
America down to a regional and individual city level. In the summer,
power traders are the most sensitive to small changes in temperature, cloud cover, precipitation and wind. Sea breezes or
thunderstorms over downtown cities create rapid and significant
changes in electricity demand. Therefore, meteorologists providing
information to power traders have to be in tune with radar and satellite images on a constant basis during the trading day.
Agriculture
Reuters, May 2013: “After a cold and wet spring in most of the US
crop belt, farmers have seeded 28% of their intended corn acres, up
from 12% a week earlier but far behind the five-year average of 65%,
… Chicago Board of Trade corn and soybean futures were trading
higher on Tuesday, due in part to the slow planting pace that threatened to trim 2013 production prospects.”
October 9, 2012, the Financial Times reported that hopes for bountiful
crops in South America fell after forecasts reduced the likelihood of
El Niño conditions developing, reducing the probability of abovenormal rains during the growing season.
Bloomberg reported on May 2, 2013, “Oklahoma wheat production,
already expected to decline 45% from a year earlier, may fall further
as freezing weather tonight threatens crops.”
September 12, 2012, The New York Times story, “US Lowers Forecast
of Crop Yields for a 3rd Time as Record Heat Lingers,” reported that
the USDA lowered forecast corn and soybean yields as record heat
added to drought damage.
The normal daily meteorological operations used in the energy business can be extrapolated to other commodity markets for which
weather changes/influences the supply or demand for a commodity.
The most obvious are the agriculture markets. The planting season
72
03 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:44 Page 73
A DAY IN THE LIFE OF COMMODITY WEATHER
for corn or soybeans could be delayed or run ahead of time
depending on spring temperatures and rainfall. Too much rainfall
does not allow planting processes to take place on muddy fields. In
addition, corn needs a minimum of 50°F and adequate moisture for
germination. If soil temperatures remain below 50°F after planting,
damage to the corn seed can be severe. Therefore, the germination
process could be curtailed. A cold spring, such as the spring of 2013,
will delay the planting season and make the corn more susceptible to
summer heat during pollination. In the summer, drought conditions
and temperatures above 95°F with low humidity can cause damage
to the exposed silks, potentially damaging pollen. During this
period, weather forecasts of potential heatwave across the US Corn
Belt can create a quite volatile price action in the corn market.
Transport
On January 4, 2013, Time reported that drought conditions could
disrupt barge traffic on the Mississippi river, disrupting corn,
soybean and grain transport.
Drought conditions in the Midwest and Ohio Valley can affect the
river levels at the Mississippi and Ohio rivers. Coal and agricultural
barges might be restricted from travelling across the low levels of
these rivers. Supply of coal and agricultural goods could be affected
on a regional basis due to transportation restrictions. Even nuclear
power plants can be affected by drought conditions: nuclear facilities
need large amounts of water for cooling purposes. After the water
has been utilised in the plant, it is discharged back to a nearby body
of water at a higher temperature. State and federal regulations
prohibit nuclear plants from continuing operations once the water
temperature reaches a certain threshold. There is a two-fold issue
here: it compromises the reactor safety and affects aquatic life.
Livestock
January 2013, Bloomberg reported, “Hogs futures climb as US cold
may hinder supply”, noting that Northern temperatures of –10–15°F
might disrupt the movement of animals to market.
May 2, 2013, Farmers Weekly reported that UK livestock deaths
exceeded 100,000 because of March blizzards and extreme freezing
weather.
73

COMMODITY INVESTING AND TRADING
A cold wave creates stress in cattle, despite the bovine being
extremely tolerant to low temperatures. An adequate winter coat
and body condition in addition to availability of food and water help
them to withstand the cold. However, the bovine will lose body fat
during a cold event and in many severe cold temperature events,
hypothermia and death can occur. Newborn calves are also at high
risk of death during cold weather events. The cattle markets typically
react in quite a volatile way when these weather events occur in the
Texas/Oklahoma Panhandle and lee side of the Rocky Mountains.
Softs
May 29, 1997, The New York Times reported that “Fears of Freeze in
Brazil Push Coffee Prices to 20-Year High.”
July 3, 2009, Bloomberg reported that cocoa crops in Indonesia and
Ecuador could be damaged by El Niño conditions, bringing lower
rainfalls.
Coffee futures can become quite volatile if strong cold events affect
Southern Brazil. Brazil is the largest coffee producer and the only one
threatened by frosts. The coffee plant cannot tolerate frost. Depending
on frost intensity, the flowers get killed or the entire tree can die. If the
plant dies, then new plants need to be planted – and it can take around
three years for them to bear coffee cherries. Vietnam is another large
producer of coffee but the main weather threat to coffee production is
the landfall of typhoons into that country. Cocoa futures have their
main weather risk in droughts. Western Africa, especially Ivory Coast
and Ghana, are the largest producers of cocoa in the world. Lack of
sufficient moisture causes the budding pods to wither.
CONCLUSION
The basic tools of operational weather forecasting for the commodity
markets are essential as an invaluable source of information for
traders. All these operations can be reduced to one goal: the best
weather fundamentals for forecasting supply and demand changes.

Oil and Petroleum Products:
History and Fundamentals
Todd J. Gross
QERI LLC
In this chapter, the conversation on crude oil will be broken into two
main parts. The first section will cover the basics and mechanics of
the current global market, while the second will address historical
price perspective and why the state of the price exists as it does. In
the first section, the basic fundamental and seasonal price drivers of
the new global marketplace for crude oil will be examined.
Subsequently, the chapter identifies the tendencies of crude oil
pricing based upon supply and demand processes that effectuate
seasonal price movements. Some details on the characteristics of
crude oil that can drive price, including quality, grade, location and
transportation, will be next. Finally, the section will conclude with a
discussion of pricing and trading.
The second part will discuss price perspective. It will address how
a US$17/bbl commodity in 2002 could become a US$147/bbl
commodity by only 2008. It will question why the globe always
seems to be running out of oil, while, so far, that fate has yet to be
realised.
WHY OIL?
Critical fuel and elasticity
What can you use crude oil for? This question has a strange, somewhat counterintuitive, answer: not much! However, when crude oil
is delivered to and processed through a refinery, this answer
becomes very different.
75
04 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:46 Page 76
COMMODITY INVESTING AND TRADING
Crude oil and its products are critical fuels to the world economy
and have huge effects on our daily life. Whether you are using a
plastic cup, filling up your car, heating your home during a cold
winter, or fuelling farm equipment to plant, harvest and bring crops
to market, petroleum plays an important role. The uses of petroleum
products are generally linked to essential modern human needs, and
the demand for crude oil is generally inelastic.
Examples can be too real for those who were waiting in queues in
the aftermath of Hurricane Sandy on the East Coast of the US in
October 2012. Having unfortunately been affected first hand, the
return of 2+ hour queues to fill your car or electric generator,
rationing and police presence at stations resoundingly begs the
inevitable question … why don’t we just use something else?
Certainly those in New Jersey and New York City would have
instantly shed their place in the queue for a readily available and
cost-beating alternative, but they could not.
There are many reasons for this, most of which point to the factors
of inexpensive cost and infrastructure. Crude oil and its products
have been the least-expensive source of energy across many areas of
the economy for decades. This fact has led to an explosion of
petroleum-related infrastructure that services most daily needs
without a reliable inexpensive alternative. Tankers, refineries,
pipelines, trucks, stations and home furnaces point to a petroleum
infrastructure that makes our society reliant on them while offering
no credible alternative.
These issues – infrastructure, price and convenience – have caused
a generally limited elasticity of downside demand, which is
supported by the data. As Figure 4.1 shows, the drop-off in
Organisation for Economic Co-operation and Development (OECD)
demand in 2008–09 was large in absolute terms, but less impressive
in percentage terms: only a 6% decline during the worst recession
since the 1930s. Furthermore, the West Texas Intermediate (WTI) oil
price could barely get back to 2004 levels of approximately
US$50/bbl on a quarterly average basis. This was a level that had
actually not been seen prior to 2004. Such an effect points to a generally increasing price trajectory since the early 2000s. The elasticity of
demand is roughly a 0.3 ratio to the change in GDP in OECD countries. Essentially, if the OECD GDP increases by 1%, the demand for
crude should increase by approximately 0.3%.

This phenomenon is a stark contrast to non-OECD growth and
elasticity. It is partially due to the fact that total US demand peaked
in the 2004–05 time-frame. In Figure 4.2, a much higher elasticity of
demand is indicated for these non-OECD countries. This ratio is
closer to 0.7. With the OECD and non-OECD countries accounting
for about equal amounts of demand, the average elasticity is approximately 0.5.
However, Figure 4.2 shows another important point. Observe the
size and scale of the downturn in the non-OECD during the period

we focused on in Figure 4.1: the 2008–09 period. The demand profile
is skewed higher in the non-OECD countries. Growth rates are
higher and the recession area of 2009 is shallower. Does this come as
such a surprise considering Chinese growth rates of nearly 8%, along
with the many emerging economies growing their manufacturing
base? Certainly not; all of these factors lead to limited elasticity of
downward demand for crude oil.
Seasonality
Crude oil and its petroleum products also exhibit significant seasonality. In Figure 4.3, the monthly demand from 2008–12 along with the
US Energy Information Administration (EIA) projection for 2013
shows that, even although each year exhibits a different slope
(largely due to macroeconomic developments such as the economic
downturn at the end of 2008), the shape of the demand curves are
nearly the same each year. Basic forces driving oil demand are
approximately the same from year to year. January is plagued by

OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
some refinery turnarounds and holidays, such as the western New
Year and Chinese New Year. Also, it seems like a low level but, as
demand increases on average year on year, the January “low”
demand is actually on the upswing from the previous November’s
trough. By February, some refineries return to service around the
globe to meet heating demand in the northern hemisphere. Then,
there is the major second quarter fall off. As spring approaches, the
global refinery complex goes into major turnaround mode.
With major refining regions such as the US taking much of the
refining infrastructure down for maintenance ahead of the
burgeoning summer seasonal usage, along with the moderation of
winter temperatures across the northern tier, demand for petroleum
tends to sag, culminating in the lowest demand period coming in
May. In the second half of the yearly cycle, demand escalates. US
demand for driving and transportation fuel picks up as many take to
the highways for summer vacation. The transportation fuel demand
increase is not only seen in the world’s largest oil consumer but
generally around the globe, culminating in September. The strength
of demand in September is noticeable compared to many other
months. Driving demand is still strong, early pre-winter seasonal
restocking of distillate and heating fuels in Western Europe is afoot
and the global refining industry has yet to go into its autumn maintenance mode. Finally, the waypoint of August and the third quarter
has exhibited stronger demand as air conditioning usage from developing nations such as Saudi Arabia have kept demand strong while
many are on holiday.
Finally, as can be seen in Figure 4.4, the cycle is complete with the
second refining maintenance season in full swing across the globe as
we enter the fourth quarter. More vacuum distillation units (VDUs)
and atmospheric distillation units (ADUs) are down for maintenance
this time around as opposed to fluid cat cracking units (FCCUs),
which tend to monopolise the spring maintenance season.
Crude grades and locations
Crude oil, when it is taken out of the ground, either offshore,
onshore, using traditional methods or with hydraulic fracturing
(which has precipitated tremendous gains in onshore drilling, especially in the US), can come with many different chemical make-ups.
Based on the main use for crude oil of refining, each crude grade has

been tagged with two defining characteristics: light/heavy (based on
the number of carbon atoms) and sweet/sour (depending on the
sulphur content). Grades are then given a name corresponding to
their respective production field name and/or geography, such as
WTI, Brent Blend, Venezuelan Orinoco, Indonesian Minas,
Malaysian Tapis, Saudi Arab Heavy, Oman, Ecuadorian Oriente,
Nigerian Bonny Light and Dubai blends.
The EIA defines light as crudes with an API gravity above 38,
heavy as crudes with an API gravity of 22 or below, medium as those
that fall between 22 and 38 degrees, with 31.1 API as the dividing line
between light and heavy.
According to “Platts Energy Glossary”:
API gravity = (141.5/specific gravity at 60 degrees F) – 131.5.
As for sulphur content, the dividing line is approximately 0.5%
sulphur, where a reading greater than 1.1% sulphur is considered
sour and a reading <0.5% is considered sweet. Figure 4.5 gives the
relationship between most benchmark crudes and where they fall on
the light/heavy, sweet/sour spectrum.
Generally, the process of refining is a chemical process that
enables the breaking and recombining of chemical structures
through heating (as in a VDU or an ADU) or by catalyst (such as an
FCCU), in order to produce petroleum products for commercial use.
Heavy crudes have a higher proportion of large molecules that are
harder to break down, while light crudes have a higher proportion of
smaller molecules. This leads to the lighter crudes that can produce

around 40% gasoline versus closer to 20% in the heavier crudes.
These heavier crudes will, in turn, produce heavier distillates to the
tune of around 60% of the barrel. These types of distillates can go to
make heavier materials such as asphalt. In refining, when burning
crudes in a refinery with heavy sulphur content, the output can emit
sulphur dioxide (SO2) or hydrogen sulphide (H2S), a poison gas.
Thus, to meet certain continually stringent sulphur specifications for
petroleum product production, a desulphurisation process has
become increasingly necessary in refineries. These processes help to
refine more sour grades to meet specifications of products such as
diesel, low sulphur diesel or ultra-low sulphur diesel that have specifications of >500 ppm, <500ppm but >10 ppm and <10 ppm,
respectively (ppm = parts per million). The crude mix has been
moving globally over time towards a heavier (higher) sulphur mix,
which is why the long-term refinery strategy has been to upgrade
their refineries to be able to handle such lower-quality crudes.
Upgraded refineries have been caught between more sweet crudes
and condensates taken out of the ground, and the many global
disruptions in locales such as Libya, which have been throttling
supply.

OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
Furthermore, locations of crudes and their availability have a
huge impact on the type of refinery operations at a specific refinery.
Although most refinery operations are very secretive about their
incoming crude oil slate, some refineries match very well with their
import crude oil.
Let us take Chevron and its assets in the western part of the US,
along with the corresponding crude oil inputs.
Here is a good example. Table 4.1 comes from the EIA website that
tracks company-wide imports on a monthly basis. Why would
Chevron import medium-heavy oil (19–24 API degrees) that is
medium-to-high sulphur (1–2.01% sulphur) from Ecuador to El
Segundo, California? In Figure 4.5, the specs fit Ecuadorian Oriente
Blend well and, considering Chevron has E&P operations in
Ecuador, this would seem to make sense. Ecuador, being on the
western side of South America, has relatively easy transport access to
California, as opposed to the US Atlantic Coast or to many other
places. This crude is a natural fit for California, but why El Segundo?
The answer makes the picture even clearer. Chevron owns and operates the El Segundo refinery. The reason that the crude is a natural fit
for this refinery is no accident. Chevron intelligently spent quite a bit
of money to upgrade this refinery to the specifications that would
enable it to run such a complex refinery in the state of California (the
most difficult place to refine in the US) and, at the same time, have
the capability to take the medium-heavy, medium-higher sulphur
crude oil of Ecuadorian Oriente.
Locations of major oil supply to demand and limitations of the
transport grid
The world’s oil supply has specific areas of concentration, with many
players moving in and out of prominance over decades. Their relevance is predicated upon their ability to cultivate reserves according
to current economics (as in Venezuela and Iran, Brazil and Angola),
on technology and each country’s willingness to adapt it (as in the
US, with hydraulic fracking) and on their ability to install an infrastructure that will enable production to grow and hasten its delivery
to market. On the other side of the coin is the ability for the crude oil
being produced to match the corresponding refining capacity. This
match up enables the easy refining of demanded and legally
permitted petroleum products.

As we can see in Figures 4.6 and 4.7, production from the Middle
East has historically been sent to the refining areas of the Gulf Coast
of the US, as well as many other refining regions across the world.
However, in response to refining capacity additions and subtractions
by region, oil trade flows have changed. The ability of western
nations to continue to compete globally on refining has become
suspect. The US and Western Europe found their great refining
centres under tremendous duress in 2011. Atlantic Basin crude oil
prices, generally indexed to Brent and imported, were being used as
feedstock to produce higher and higher quality (lower sulphur
content) products. These product specifications were mandated by
the EU and US governments. In addition, these refiners faced evermore stringent quality standards on petroleum products while
having to combat a reduction in petroleum product demand since
2008. Furthermore, higher fuel efficiency and the greater acceptance
of clean technologies have also cut into demand.
The business case for continuing to produce petroleum products
in these two jurisdictions if a refinery was lower on the Nelson
Complexity scale and its refining power was generally simple was
becoming increasingly unprofitable. Examples of victims of these
two simultaneously negative phenomena were PetroPlus, the largest
independent refinery in Western Europe, Sunoco, the biggest
refining presence on the US East Coast, and ConocoPhillips, who
divested its downstream business and spun it off into Phillips 66

(with this last case probably augmenting efficiencies in management). The replacements for these refineries were generally Indian,
Chinese and Middle Eastern refining capacity additions. With fewer
regulations for start-up, cheaper labour (none or fewer union labour
constraints) and closer proximity to the source of crude oil, the
trends depicted in Figure 4.7 are not only set to continue, but to be
accentuated in the coming years. After all, no major refineries have
been built in the US since 1976. Capacity grew solely through
upgrades and increases in complexity. Meanwhile, Asian refiners,
less hindered by regulation and clean air rules, have been building
brand new, more efficient refineries that can actually fill the gaps left
by those archaic, decommissioned refineries of the west.
However, as this all seemed to be speeding out of control in the US
and Western Europe, a new technological breakthrough came along
just in time to give at least a temporary reprieve for many US East
Coast refineries. Domestic crude oil, produced through techniques of
hydraulic fracturing from the interior of the US, has made its way
across the country to the refining centres in a cost-efficient way. This
trend has given some of these refineries hope. We will talk more
about the phenomenon later in this chapter but, with the Carlyle
Group purchasing part of the Girard Point refinery from Sunoco and
Delta Airlines purchasing the Conoco Phillips Trainer, PA refinery,
the progression of this global change in regional refinery economics

seems to have been stayed. Additionally, the US Gulf Coast has been
importing less and less crude to run its refineries, and within 2–3
years the region should not need to import crude oil at all.1
The future trajectories of production, refining and storage are
beginning to change the market and may slowly change how crude
oil and petroleum are priced. Despite the extraordinary growth in US
production, there is little risk to the status of the Middle East and
former Soviet Union (FSU) as major producers. The inclusion of
Iraq’s huge reserves under a market-oriented and ambitious regime
provides optimism for the continued strength of Middle Eastern
crude oil production. With Brazil and Russia having gained in
economic prominence, these countries will also have the ability to
marshal larger resources toward oil exploration and production
(E&P) for increasing contributions in the global crude oil supply mix.
Also, new technology and high prices have encouraged a renaissance in US oil production.
The real issues that have arisen from this sea change are logistical.
How does the crude get from production areas to the refiners, and
what are the risks along these routes? The flow of crude oil from
Middle Eastern countries to jurisdictions East of Suez has been
growing for decades. However, with more and more of global oil
production heading in this direction, the world oil transit choke-

Let us talk about the granddaddy of them all at first, the Strait of
Hormuz, which is located between Oman and Iran and connects the
Persian Gulf with the Arabian Sea. Here, roughly 35% of all seaborne
traded oil and 20% of all oil traded worldwide passes through on a
daily basis. More than 85% of these crude oil exports go to Asian
markets such as Japan, India, South Korea and China. At the
narrowest point, the Strait is 21 miles wide and the width of the shipping lane in either direction is only two miles, separated by a
two-mile buffer zone. The alternatives are woefully inadequate.
Pipeline replacement capacity currently only offers 4–5 million
barrels a day of unused capacity, and trucking would add only a
maximum of a few hundred thousand barrels per day. Most tankers
going through the Strait of Hormuz run greater than 150,000 deadweight tonnage (DWT) – these are very large tankers. A block of the
Strait of Hormuz would result in a shortfall of undelivered crude oil
of perhaps up to 12 million barrels a day.
The Strait of Malacca is the other main strategic point. It is
located between Indonesia, Malaysia and Singapore (where the big
Pulau Bukom 500,000 barrel-a-day Shell refinery operates), and
links the Indian Ocean with the South China Sea and Pacific Ocean.
88
04 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:46 Page 89
OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
This is the key chokepoint in Asia. With 13.8 million barrels per day
(mbpd) flowing in 2007, the Strait had ratcheted flows up to an estimated 15.2 mbpd in 2011. At the narrowest point, in the Phillips
Channel of the Singapore Strait, Malacca is only 1.7 miles wide. If
the Strait was blocked, nearly half of the world’s fleet would have
to reroute around Indonesia. With so much crude flowing through
this waterway, it would not go undelivered as in the case of a
blockage of the Strait of Hormuz; it would just have to be rerouted
at greater costs and time to market.
The rest have their strategic interests too. The Turkish Straits are
important for western pricing because it is a main thoroughfare that
transports Russian crude exports, as well as exports from Azerbaijan
and Kazakhstan, to Western European refineries. Weather often
impacts transit in winter, forcing additional transit time of up to
weeks in some cases. Finally, a Bab el Mandeb closure could keep
Persian Gulf tankers from reaching the Suez Canal as it is located
between Yemen, Djibouti and Eritrea, and connects the Red Sea with
the Gulf of Aden and the Arabian Sea. Most transit goes north to
destinations in Europe, US and Asia. If impassible, it would redirect
3.4 mbpd around the southern tip of Africa, a significant addition of
transit time.
Crude pricing and trading
Not all crude oil that is produced and delivered goes directly into the
refinery for processing. The crude that awaits refining in any timeframe is held in storage. Storage is the most significant statistic of
over- or under-supply in the crude oil market.
Most notable has been the effects of storage levels and capacity in
Cushing, OK, the delivery point of the CME/Nymex WTI crude oil
futures contract. Being a landlocked area with limited capacity and
limited transit to and from the storage tanks, the Cushing phenomenon played a major role in the term structure of the Nymex futures
contract through 2010. As one can see from Figure 4.10, a significant
amount of storage capacity has been added to Cushing inventories
since the third quarter of 2010. This fact has alleviated some of the
risks of storage congestion and stock-out phenomenon that has
plagued this storage area, and therefore the Nymex pricing of
prompt/term spread relationships.
When storage levels approached high percentages of capacity, the

WTI market would go into a strong contango. Known as storage
congestion, this has not been overly studied in the “theory of
storage” and academic circles. The volatility in the markets is usually
greatest when the market is near stock-out capacity, and when there
is not a credible alternative to satisfy demand (Kaldor, 1939;
Working, 1948, 1949). The opposite is also true. For certain commodities, where storage is not universal and is limited, and there is little
outlet for continued production, the price will pick up significant
volatility as full storage is approached. Spot prices will tend to
become more volatile when storage operators are not seasonally
involved in the market or their facilities are near capacity (in a similar
fashion to how front-month futures price volatility tends to increase
as expiration draws near (Samuelson, 1965)). As prices plummet and
the market becomes more volatile, the percentage movement in
underlying pricing and spreads can rival even the most extreme
stock-out scenarios. Research from the likes of Carlson, Khokher,
and Titman (2007) and Evans and Guthrie (2009) has suggested that
there is more of a U-shaped relationship between spot price volatility
and the slope of the term structure of forward prices. Strangely, both
phenomena are less likely with greater storage capacity!
We can see in Figure 4.11 the takeaway points for Cushing crude oil
and many additions to alleviate the so-called bottlenecks that inhibit
the transit of crude oil to the Gulf of Mexico’s major refining area have
been, and continue to be, implemented. However, generally, there
are inflows from local production and the incoming crudes off of the
90
04 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:46 Page 91
OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
Enbridge pipeline into the Cushing area. Outflows had been going to
the only consumers on the block, the local refineries. Other pipeline
capacity is in full swing, such as the Seaway pipeline reversal (it used
to bring crude up from the US Gulf Coast to the PADD II refineries
until domestic Bakken and Southern Canadian production exploded),
alleviating most bottlenecks. The consuming pipelines name the
destination. BP is flowing towards Chicago (or, more specifically,
Whiting, Indiana) to its 410,000 bbl/day Whiting refinery. Likewise,
the Ponca line heads to the Phillips 66, Ponca City refinery (at 195,000
barrels/day) and the Ozark pipeline takes off to St Louis area to
supply the Phillips 66 (formerly Conoco Phillips) Wood River
Refinery at (300,000+ barrels/day). Also worth noting is CVR
Energy’s 115,000 barrels/day Coffeyville, KS refinery, which has its
own line coming from the Oil Hub. Then there are other inputs, such
as the Enbridge Spearhead pipeline that delivers more Canadian
crude to Cushing.
Furthermore, Figure 4.11 shows existing and proposed pipeline
expansions, which continue to address transport issues of crude oil

from production areas in the north to the refining centres in the Gulf
Coast.
Finally, Figure 4.12 points out the more important figures for
pricing the WTI near term structure. Two very different states of the
world existed for prompt second-month WTI spreads in September
2008, and then quite the exact opposite in January 2009. On
September 13, 2008, the 110 mph Hurricane Ike crashed into the
Houston Gulf Coast, delaying crude oil imports and disrupting
infrastructure up the Houston Ship Channel and the Loop, to the
point that Cushing inventories plummeted and the spike in
prompt/second WTI spread blew out to US$29/bbl on expiration
(See Figure 4.14). Then, only four months later, the opposite was
true. Crude oil inventories were approaching a limit at 80% of then
storage capacity at Cushing, Oklahoma, and global inventories were
dramatically swelling. With capacity at just under 40 million barrels
in early 2009, the inventories ballooned to just under 35 million

barrels (Figure 4.13). The ensuing change in prompt second-month
spread was dramatic.
In the 2000s, the small glimmer of technological advancement in
hydraulic fracturing almost entirely captured headlines in the
natural gas arena as a production game changer. The realistic impact
on global crude supplies was initally discounted because, although
technology made additional US production theoretically possible,
the barrels could not be moved from these interior locations due to
the lack of midstream infrastructure. Pipeline assets usually take
onshore crude oil from E&P areas to refinery gates for easy loading
into the facility to make product. The completion of many new assets
to fulfill additional takeaway-capacity needs seemed several years
away. There was a trend towards the bankruptcy of East Coast
refineries that had similar issues to that of their cousins in Europe,
and the stranded nature of this new crude production’s location. The
only outlet seemed to be to get the oil to Cushing, OK. However,
events have begun to change this state of affairs, although a lot more
needs to be done to rectify the two main dislocations in the oil and
products markets that are inexorably intertwined: the Brent/WTI
pricing mechanism and the East Coast refinery market.
The Brent/WTI spread market flourished because of two very
important attributes, that were both financial and physical in nature.

The flagship contract on the Nymex was WTI, which fostered an
active, entrepreneurial place for hundreds of traders to provide
liquidity for the crude oil futures contract. There was always a transparent price that could be transacted. Likewise, the counterpart in
the UK was the Brent Blend contract, which started on the IPE before
being owned by the ICE. The Brent contract had a little different
make-up. Although not as liquid as a futures contract, it had the
unique characteristic of being directly tied to Dated Brent, a more
commonly used benchmark for the spot price of crude oil.
Furthermore, the the two contracts were easily linked as there was a
direct route to get Brent to the same place as WTI. Take a loading on
a tanker in the North Sea and drop it off at the Loop, the Louisiana
Offshore Oil platform, or in the Houston Ship Channel. The crude
could then be piped onshore and up yet another pipeline, sending it
north up to the Midcontinent and Cushing, OK (one of these
pipelines being Seaway). Brent typically traded at a discount to WTI,
because most incremental refining barrels were absorbed by the US
refining machine and therefore Brent traded at a discount to Light
94

OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
Louisiana Sweet (LLS), generally by the cost of transportation to the
US Gulf Coast (USGC). LLS and WTI were generally linked by inexpensive pipeline economics that would bring crude from the Gulf via
the pipeline. There existed a very liquid market in buying and selling
Brent cargoes, hedging with more liquid WTI futures and trading the
spread back and forth actively.
The spread (and its economics) were severely disjointed by the
unexpected explosion in Midcontinent supply coming from Bakken
shale in the US and production from Southern Canada. This increase
came at the same time that production in the North Sea was
declining to a point that there was a noticable drop in production out
of the Brent, Forties, Oseberg and Ekofisk (BFOE) cocktail.
Specifically, Nexen’s Buzzard field of 200,000 barrels per day,
approximately 10% of the North Sea production, has had major,
continuing maintenance problems. The BFOE cocktail that cargoes
were priced off of had compounding issues when Buzzard was
down. Buzzard Forties production, one of the lowest-quality crudes
in the cocktail, had a knock-on effect on price. As production went
down, supply would shrink drastically. In addition, the cheapest
element of the cocktail was diminished, leaving even more expensive
crudes to make up the price. The cocktail had been priced on the
cheapest-to-deliver crude. This phenomenon adds extra elasticity to
the Brent/WTI movement that had come to plague the market.
Meanwhile, many remedies were being sought to alleviate this
price differential on Brent/WTI. While the East Coast and Gulf Coast
refineries were having their crude feedstock priced off of Brent, the
Midcontinent PADD II refineries enjoyed the economics of landlocked Cushing pricing. There was financial incentive to redistribute
the crude and try to alleviate bottlenecks. The sale of the Seaway
pipeline and the reversal of flow has begun to help, but much more
needed to be done. The Brent/WTI price differential (still at Brent
US$20 over) did not look like it would relent soon. The reversal of
Seaway, which has removed 150,000 bbls/day along with another
250,000 bbls of throughput to be added in 2013, should help. The
political football of the Keystone XL pipeline, as well as many lesserknown avenues, had been put to work to alleviate the glut and to
take advantage of the US$20+ price differential. However, unforeseen issues such as the limited storage tank capacity at Jones Creek,
Texas, had diminished the Seaway pipeline’s effectiveness. This final

04 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:46 Page 96
COMMODITY INVESTING AND TRADING
outlet for the Seaway pipeline only boasts 2.6 million barrels of
storage and has limited the ability of Seaway to move all of its
400,000 bbls/day capacity to the Gulf. These constraints had
prevented a resolution of the spread relationships.
With many alternatives for crude transport unavailable, the
markets turned to an old school form of crude oil transportation: railroads. Rail loadings of oil have been soaring and the economics make
sense. With many new terminals being built to handle much of the
throughput, the transport of crude via rail has been able to alleviate
some of the issues. This solution has changed the equation enough to
rationalise the economics of two East Coast refineries. With the hope
of getting Midwest crude oil, the business case has changed from an
unprofitable venture such as those in Europe to big opportunities for
those including Monroe Refining (a division of Delta Airlines) and
the Carlyle Group. Both investors have bought two main East Coast
refineries previously set for closure because of poor economics. The
ability to receive shale crude oil as feedstock has helped to make the
business case to keep these refineries open. Furthermore, in Monroe
Energy’s case, their supply chain of jet fuel in the New York market
and ability to supply competitors makes it a sound investment, with
some personnel who used to work at the refinery already being part
of the Monroe team.

As Figure 4.15 shows, there has been a jump in railcar loadings
with petroleum. With growth near 45% for 2012, rail movement of
crude oil is showing itself as the stopgap measure of choice between
the production and demand today and the time when lower transmission cost pipelines are built. Economics are showing the railing of
crude from Bakken to the Gulf Coast as an approximate mid teens
per barrel cost. These economics have enabled such railing. Risks to
this method have been highlighted with the crude oil rail tanker accident July 6, 2013 in Lac-Megantic, Quebec.
Crude markets and trading
Oil is traded physically in many corners of the globe. With benchmarks such as Dated Brent off the BFOE pricing, the Japanese Crude
Cocktail (JCC) pricing many far eastern contracts, Oman/Dubai
pricing a lot of the Middle East sour crudes and FSU Urals pricing
much of Eastern Europe and distillate products, these crude oil
97

benchmarks are all interrelated. Global pricing is influenced by what
refining capacity is operating or down for maintenance, and generally if there are problems in loading (for example, in Nigeria when
there are militant attacks). Maintenance in fields such as the Buzzard
field in the North Sea can also have an outsized influence on these
benchmarks. Grades are crucial and which refineries take those
grades can make the difference between a wide or tight sweet/sour
spread differential. Crude oil is mainly moved on Dirty tankers with
>150,000 DWT, or very large crude carriers (VLCC).
Specifically for crude oil, Dated Brent is the most widely accepted
global crude oil benchmark, and always faces intense scrutiny from
producers, end-users and regulators. Dated Brent is generally used
as a sweet crude benchmark and prices crude in the North Sea, West
Africa, the Mediterranean, South and Latin America, Canada,
Central Asia and Russia. More than 60% of the world’s internationally traded crude oil is priced against Dated Brent.3 Dated Brent is
the price assessment of physical cargoes of North Sea light sweet
crude oil. The term “Dated” refers to the physical cargo price for
North Sea Brent light crude which has been allocated a specific
forward loading date (10–25 days ahead). The North Sea light sweet
crude oil grades – Forties, Oseberg and Ekofisk – are also deliverable
against the Dated Brent contract known as “alternative delivery”, as
the combination of all four crudes is known as BFOE. This combination gives Dated Brent a supply of approximately 1.4 mbpd and
provides enough liquidity to sustain it as a benchmark. The window
for pricing Brent occurs at 4:30 pm, London time. When prices of
Dated Brent are high, the North Sea attracts crudes from West
African and the Mediterranean, while when the benchmark price is
low, North Sea pushes crudes to other places, such as the US Gulf
Coast. Historically, Malaysian Tapis and Indonesian Minas had been
the benchmarks for sweet crude in the Far East and Asia. However,
with production becoming smaller and smaller and fewer barrels
being available for export, the region has turned to Dated Brent for
much of its pricing, with even Indonesia pricing its barrels off this
global benchmark. The Asian version of Dated Brent is priced off a
Singapore pricing window at close of business 4:30 pm, Singapore
time.
As for sour crude oil, Dubai had historically been an Eastern
benchmark. However, as physical export supplies became scarce in
98
04 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:46 Page 99
OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
the Asian/Pacific regions and import demand climbed to levels
greater than 17 million barrels per day, these benchmarks needed a
little help. Therefore, the Dubai benchmark has added Oman and the
Dubai Mercantile Exchange has touted its Oman futures contract
that has a delivery point east of Suez and 860,000 barrels/day of
export volume. As for the pricing of many grades of crude for export,
these benchmarks enable pricing schemes, but vary based upon
destination. For example, Saudi Arabia may price exports to Europe
based upon the Brent Weighted Average (BWAVE) price, its exports
to Asia based upon Oman and Dubai and its exports to the USGC
based upon Argus Sour Crude Index (ASCI), an index of delivered
sour crude to the USGC.
Product points have just as much relevance. With product trade
and transport becoming more of the global petroleum trading
market through the 2010s (International Energy Agency, IEA, 2012),
one has to be cognisant of those that produce and those that will
receive. The ports of interest are mainly the USAC, USGC, Sullom
Voe terminal in the UK, Amsterdam, Rotterdam, Antwerp (ARA),
Ras Tanura in Saudi Arabia, Singapore, Chiba in Japan, Shanghai
and the MED terminals in Fos Lavera near Marseille, France. Most
product pricing hubs are aligned with an important maritime port,
usually one or many large refineries and, of course, most importantly, storage facilities for petroleum products.
Most petroleum products are moved on barges or clean tankers of
around 60,000 DWT. The terms FOB (free on board) and CIF (cost,
insurance and freight) denote whether the pricing is based on the
buyer providing transport and the seller delivering the barrels “on
board”, or the seller covering transportation and insurance costs to
deliver the cargo to the buyer’s destination port.
On a global basis, the trend is for less refining activity out of
Western Europe and for those losses to be supplanted by gains in
India and China. The growth of the giant Jamnagar complex in India,
along with the upgrade of the Essar Oils refining complex from
300,000 to 600,000 barrels per day, has shown India’s high-profile
strength in the refining sector. China has added a multitude of
refineries since the late 2000s. These refineries have been located in
many different areas of China, and although not aggregated into a
single massive refining complex, they represent huge additions in
refining capacity.

As this was taking place, the bankrupcy proceedings of PetroPlus’
mainland European holdings was happening. These older, less
complex refineries, which originate crude oil from long distances,
and which are forced to deal with organised labour issues, have
become less competitive on the global landscape. The final straw was
the recent Libyan revolution that took away the much-needed sweet
crudes that some southern European refineries had used for feedstock, not easily replaced by the sour FSU Urals blend that was the
most readily available swing supply at the time.
As refining moves East, pricing and benchmarks for the world’s
refineries will change. Figure 4.17 shows many of the benchmarks for
crude oil and the pricing points. As the North Sea faces continuing
decline in output capacity, the US production pushes Nigerian and
Angolan crudes to the East, and refining interests procure more
marginal barrels from Middle East sources, some of the refining
benchmarks may move towards the Oman contracts on the Dubai
Mercantile Exchange.
The US is a different matter. With its strong refining base in the
USGC, its excess capacity has been mobilised to export products to
certain markets, many located in South America. As South American
demand for products has continued to climb, along with the closure
of the Hovensa refinery on St Croix, the Valero Aruba refinery and
the chronic maintenance needed at the giant Paraguana refining

complex in Venezuela, US Gulf Coast refineries have been recruited
to export products to meet demand in the south.
Several commodity exchanges offer futures contracts, some which
may be settled by physical delivery of the underlying crude or
product, and some that may be settled financially. These futures are
widely used by producers, refiners and large consumers of crude
and products for price risk management, and are also traded by
speculators and investors who desire exposure to energy prices. The
main futures and options markets are traded on the CME and the
Intercontinental Exchange. The products listed are WTI, Brent, UltraLow Sulfur Distillate (which was previously known as Heating Oil),
Gasoil, RBOB and many other locational contracts (such as flatpriced delivery points of USGC, ARA or Singapore) that are listed on
ICE or cleared on CME Clearport. Although Heating Oil and Gasoil
have been the mainstay for pricing of global distillate demand since
the early 1980s, these contracts are slowly being replaced by their
lower sulphur counterparts that are becoming a larger segment of
distillate demand, with the ICE and CME adding Low Sulphur
Gasoil contracts since 2012.
A HISTORICAL PRICE PERSPECTIVE
Figure 4.18 illustrates a historical perspective of oil prices and some
of the major effects since the early 1970s. The first commercially
drilled oil well was drilled near Titusville, Pennsylvania, in 1859 by
Edwin Drake. Even although kerosene production from crude oil
goes back to the Babylonians’ uses of petroleum, the implementation
of the combustion engine and later uses in transportation were the
main drivers of the pursuit of crude oil production. Early on in petroleum history, 90% of the world’s crude oil was in Baku, Russia, and
after a century and a half Russia has once again become the largest
producer of crude oil, but, according to the IEA report of October
2012, by 2017 the US will resume its place as the world’s largest oil
producer.
However, the history of modern oil pricing really started in 1960
with the birth of Organization of Petroleum Exporting Countries
(OPEC). During that era, Western demand for oil was mostly met by
international oil companies (IOC) and production was mandated by
quotas set by the Texas Railroad Commission. What followed was a
series of events that turned the price and availability of oil upside

OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
down. Back in 1956, M. King Hubbert’s presentation to the American
Petroleum Institute suggested a peak in US production that actually
took place (albeit for the time being) in 1970. Then, in March 1972, the
Texas Railroad Commission declared that having quota restrictions
on production was not necessary because demand had outstripped
supply and that producers could produce at their capacities. This
event ushered in the shift of power over global pricing of crude oil
from the West to OPEC. Shortly thereafter, there was the Yom
Kippur War, and, with the West’s support of Israel, the ensuing Arab
oil embargo that lasted from October 1973 to March of 1974. Prices
skyrocketed.
Once again, Hubbert’s ideas of a global production peak had
permeated into the market, now pointing to global production
peaking around 1995. With the growth in production coming from
the Middle East, and the economic changes and expansions on the
horizon set for what would become the nations of the G7 and eventually the G20, the secular movement of Western economic powers
taking from the Eastern producers became the emerging status quo.
In 1979, the Iranian revolution added another jolt to the spot crude
oil price. In late 1978, a strike by foreign workers who later fled the
country during the 1979 revolution, helped Iranian production
decline from more than six million barrels a day – from which the
production has yet to recover. The 1979 revolution led into the 1980
Iran/Iraq war, signalling a second oil price spike in a decade.
However, with the resurgence of Soviet Era assertion for energy
dominance and new technologies for exploration and production,
first the USSR and then Saudi Arabia in the 1990s stepped in to fill
the gap to become the number one and number two global oil
producers. With the emergence of a general global peace, excess
supply and better technology, Hubbert’s predictions looked implausible. In fact, in the late 1980s there were several events that helped to
vault prices lower. In 1986, with Mexico becoming a strong regional
player in the West, the Mexican government offered to price crude
delivered on a netback basis. This meant that they would price crude
oil based upon the price at which products could be sold. As refiners
were basically guaranteed profits, they produced until there was
major oversupply, which pushed WTI prices on Nymex to
US$9.75/bbl (meaning that prices were down by 80% in a few short
years). The lower price regime continued generally through the late

1980s. A perfect example was a pre-OPEC meeting headline in The
New York Times Business Section in November 1988, which read:
“Three Cheers for US$5 Oil”. At the time, Kuwait was a chronic overproducer and kept the prices down. The Saudis suggested that they
could just flood the market with oil and be the last one standing...at
US$5/bbl. This particular dynamic seemed to replay over the next
few years as a recurring theme, even although OPEC was able to
come out with an agreement in November 1988.
Kuwait’s overproduction was not such a black and white case.
During this era, OPEC quotas were actually important. They were
hard to enforce, but markets did enforce them, as otherwise the price
would plummet, and OPEC ministers were forced to act. Kuwait
was coming into its own at that time in oil production. The country
was able to invest in production and grow its production capability,
but they wanted to sell this new capacity. These aspirations eventually caught the ire of Saddam Hussein and Iraq. The Iraqis believed
that Kuwait was originally (and still was) the 18th province of Iraq,
and, due to its chronic overproduction, Kuwait was blamed for
keeping oil prices low.
Much to the disbelief of the West (even although Iraq had amassed
hundreds of thousands of troops on the border days before), Iraq
104
04 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:46 Page 105
OIL AND PETROLEUM PRODUCTS: HISTORY AND FUNDAMENTALS
invaded Kuwait on August 2, 1990 – and away went the price of
crude oil. The price peaked in October of 1990 and, when the US lead
a coalition to free Kuwait in January 1991, it ushered in an era of a
stronger Western military presence in the Gulf region, relatively
unchecked after the break up of the Soviet Union in 1989. The result
was a stable environment for oil prices throughout the 1990s. Excess
OPEC capacity trended higher throughout the decade as OPEC
nations added capacity faster than demand, and this excess capacity
reached a level not seen since the Iran/Iraq war.
In 1998, with the price of WTI trading near US$10/barrel, there
was once again trouble in OPEC. The supply situation had placed
Sunni-lead Saudi Arabia at loggerheads with Shi’ite Iran based on
pumping. By default, Saudi Arabia had become the swing oil
producer in times of market shortfalls, tightening their new alliances
with the consuming nations in the West – they had become the de
facto central bank of oil. With overproduction coming from Iran and
Venezuela, the balances were once again hard to maintain. The
market found a bottom, but not until a real resolution on production
and quotas were reached by these countries.
This market downdraft was not without casualties. With
Hubbert’s predictions about 1995 all but forgotten, perhaps the best
“trade” of the decade happened with oil near US$10/bbl. Exxon
bought its largest rival, Mobil, in 1999 at the bottom of the market.
Hubbert’s global production assessments were not off, but somewhat delayed by the one thing that has also reemerged in the
previous decade: technology. The ability to leverage existing oil
fields by pumping large amounts of water into a field and thus
expanding its production capacity, enabled big oil fields, such as the
Ghawar oil field in Saudi Arabia, to increase or sustain its production
capability when it should have begun to decline. Saudi Aramco,
boasting the best technology of any oil “company” in the world, was
defying production constraints with new technology.
Finally, around the new millenium, some old predictions began to
take hold. After the economic downdraft in 2002 precipitated by
September 11th and the South American debt crisis, the growth of
emerging economies became noticeable. The Brazil, Russia, India
and China (BRIC) economies began to grow to a point where the
consumption of crude oil and refined products were overwhelmingly dependent on the ability to find oil.
105

COMMODITY INVESTING AND TRADING
The era of finding onshore super-giant oil fields was gone. The
new cost of finding fields and extracting was increasingly being
focused on deep-water offshore finds that were expensive and risky
to excavate. With very large fields such as Mexico’s Cantarell in
decline, and the West feeling the pinch of the fall-off in production
from the Hugo Chavez regime in Venezuela, there was great concern
in the race for the marginal barrel. Areas such as the North Sea had
begun a decline that continues to the present day. The one major
bright spot that Figure 4.19 does not point out is the upswing in US
production that now boasts greater than 7 mbpd, reversing the
downward trend which was intact since 1970.
Let us now look at Figure 4.20, which illustrates the growth in
consumption of the largest driver of the decade, China. Amazingly,
since China became a net importer of crude oil, its shortfall has
grown substantially to make it the second largest consumer of crude
oil after the US. This rapid growth and migration of the populace to a
middle class that is a global consumer of crude oil products has had
a profound effect on price and excess capacity (as shown in Table 3).
According to EIA projections, this trend will continue going
forward through to 2035. With much of the future growth in liquids
consumption coming from China, India, other non-OECD Asia and
the Middle East, much of the supply growth will have to come from
somewhere. Interestingly, OPEC is showing a growth in market
share from about 40% to 42%. Therefore, the promise of Iraqi growth
may have some lasting effects on keeping OPEC share growing.
Meanwhile, as shown in Table 4.4, with the production declines in
the OECD countries, the lone shining star is the US thanks to the
shale production boom that may even supercede the estimates which
may crowd out some OPEC production growth. The IEA claims that
the US will be the world’s largest oil producer by 2017. This implies a
staggering growth rate, which may be difficult to achieve given the
typically high decline rates for most new wells in the Bakken and
Eagle Ford shales.
There are a few things to note based upon the overall trends.
Looking once again at Figure 4.18, the tightness of the supply–
demand balance that ushered in this new era of prices largely took
effect when the excess OPEC capacity shrank back below 3% of
global production (about 2.7 mbpd). At the same time, there was a
second stage ramp-up in Chinese demand (as shown in Figure 4.20)

at the acceleration point around 2003. Thus, the new price regime
entered the markets. With similar shortages during the first Gulf
war, the nominal price reached US$41 in late 1990. Contrast that time
with early 2009, in an oversupplied environment of having 6%+
excess capacity the price was only able to fall to US$32/bbl. This
price action speaks to a new price regime.
Note the price assumptions listed by the EIA in Table 4.4. These
price assumptions show a steady growth. The answer is sensible. As
excess capacity continues to be very low, price needs to ration the
market’s demand. To get 109.50 million barrels of oil out of the
ground in 2035, many new fields, unprofitable at today’s prices,
would require the ability to contribute to the global liquids production mix. Before the great recession that collapsed the markets in
2008, price raced towards US$147/bbl, an incredible feat for a
commodity that hit a low of around US$17/bbl in 2002. There was
the push of Chinese demand, the faster decline in Mexican, North
Sea and US production, and a dwindling of excess capacity to a point
where only 800,000 bbls/day was projected to stand between easily
functioning markets and an aggregate stock-out.

The demand destruction that ensued from the recession
temporarily changed the equation; however, does this risk still exist?
Just as Hubbert predicted, in early 2008 an almost universal feeling
of peak oil and high prices were beginning to be the norm. Then

came the recession, and one can see in the consumption numbers in
Table 4.3 that very little (if any) growth is expected between 2008 and
2015. The shale revolution coming from the US and southern Canada
then appeared. At US$50/bbl, these technologies are not financially
viable, but, at US$70–80/bbl, they are profitable. Once again, the
peak oil whispers have faded because of technology and may stay
quiet for a while if this technology becomes a universally accepted
means of production. However, our new pricing regime is in place.
The price assumptions made by the EIA exist so that the market stays
balanced. This theme is an important one. As we move from one
price regime to another, the effects of the market pricing is to ration
demand (as it has already done in many OECD countries since 2008)
and to price in new technologies for production that become financially viable at higher price points.
CONCLUSION
In summary, the global landscape of the market for crude oil has
many intricate influences, stemming from grade, location, politics
and its reception from its downstream counterparts at the refinery
level. The growth in emerging economies have shaken the stability of
the existing supply/demand balances, but have also ushered in a
new era boasting new methods of combating the continuous struggle
for the globe to be well supplied with crude oil. However, even as
Hubbert had predicted back in 1956, the decline of crude oil as our
main source of energy has been wildly overestimated. The cost and
the technological breakthroughs continue to preserve this
commodity as a large part of our daily lives.

Wholesale Power Markets
William Webster
RWE Supply and Trading
The objective of this chapter is to provide an understanding of how
the wholesale electricity market functions, and to explain its special
features compared to other commodity markets. Despite the liberalised electricity markets having their first beginnings as far back as
the 1990s, there probably remain few people outside of the industry
who conceive of electricity as a traded commodity. This can be easily
discerned from political discussions where there is regular pressure
on government and regulators to intervene in the setting of electricity prices.
However, an unhindered liquid wholesale market that sets prices
is an essential component of a competitive market for electricity.
Otherwise new suppliers and new generators cannot enter the
market independently. This means all the usual components of
commodity markets need to apply: the free interaction of supply and
demand, development of forward markets, the participation of a
diverse range of traders with different motivations and strategies,
and the provision of platforms offering a range of matching, clearing
and settlement services. This chapter will describe how these basic
building blocks of traded commodity markets are applied in the electricity sector, and examine some of the outcomes.
The following section will explore some of the special features of
electricity and how they have influenced the development of wholesale markets, before we look at how electricity is traded in practice
and introduce some of the products and markets that are typically
found. We will then examine the behaviour of different market
participants and explore some trading strategies, as well as review

the development of market prices over time in some important
European markets. The chapter will also seek to identify some key
issues that might affect electricity trading over the next decade, and
end by considering some of the main sources of information on electricity wholesale markets.
ELECTRICITY AS A COMMODITY
The unique characteristics of electricity
The scientific laws of electricity
The power market has particular characteristics that distinguish it
from other commodity markets. These characteristics are mainly a
consequence of the scientific laws of electricity production, transmission and consumption.
These laws mean that, for example, it is not straightforward to
trace the production and use of individual electrons across the transmission and distribution networks. Likewise, these laws mean that
the whole system has to be maintained at a constant frequency for
power plants and appliances to continue to function. There is therefore an interdependency between market participants that is not
seen in other sectors.
However, as with the peculiarities of other commodities, it is
possible to develop a traded market by introducing some approximation around the consequences of these physical laws. Just as the
market for crude oil is able to deal with, for example, different
quality grades and delivery locations, so it is also possible to get
around the specificities about electricity as a product. So, although
the electricity system as a whole has to balance on a second-bysecond basis, traded markets usually allow for market participants to
balance over a 15- or 30-minute period. These issues will be
discussed in more detail in the remainder of this section.
Dispatch arrangements
First, compared to other commodities, delivery of electricity is
strongly time dependent. It must be produced and delivered exactly
as it is used. This contrasts with other commodities that can be stored
to a greater or lesser extent. Electricity is also unlike most other
commodities in that it has a dedicated delivery network: the transmission system. For electricity provision as a whole to continue to
function, there must be equilibrium between the network, production and consumption in real time.
114
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 115
WHOLESALE POWER MARKETS
Second, if there is a failure in the overall system, it will affect a
broad range of users, and not necessarily those that caused the
failure. There is therefore a strong public-good element in electricity
supply. In particular, the electricity network can be characterised as
“non-exclusive”. If the system as a whole works, it is there for everybody and nobody can be excluded from using it. However, electricity
supply is not a pure public good, in that it is not “non-rival” (in the
same way as, for example, street lighting). It is therefore competitive
with respect to supply and consumption in that the same MWh
cannot be used twice. This means that a market structure can function in the sense that the use of electricity can be rationed through the
price mechanism.
The main issue raised by these two points is, therefore, more about
the extent to which producers and consumers can interact directly, as
in other commodity markets, or whether there needs to be a specified
regulated intermediary.
In some jurisdictions, regulators impose a strong role for the transmission system operator (TSO) in overseeing the market process,
and even in operational decisions. Under such arrangements, generators feed in all their technical and pricing information to the TSO,
who then calculates prices using this information and assumptions
about demand. Such market arrangements are characterised as
“central-dispatch” because the system operator decides how all
generation plant is dispatched on the basis of the prices and technical
information that is submitted. In effect, the TSO buys electricity on
behalf of retail suppliers and their consumers.
Meanwhile, market arrangements where producers and
consumers (or usually their retail suppliers) interact independently
are termed “self-dispatch”. In these cases, generators negotiate individually with retail suppliers via traditional traded wholesale
markets structures – ie, a variety of traded platforms and exchanges
as well as voice-broking services. The system operator then takes a
residual role in that they may adjust generation output via balancing
actions and “re-dispatch” if this is necessary to ensure the overall
security of the system.
A simplified summary of these terms is provided below.
❏ Central dispatch
Generators provide price and technical information (eg, ramping
parameters, start costs) to the system operator. The system
115
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 116
COMMODITY INVESTING AND TRADING
operator compiles an efficient dispatch schedule on the basis of
this information and expected demand. Generators run to that
schedule. The TSO calculates a price for each (eg, hour) and all
trading is based around that price (eg, Ireland, England & Wales
Pool).
❏ Self-dispatch
Retailers contract in the market with producers to meet the needs
of their portfolio of customers. Generators offer prices to the
market based on their plant characteristics and conclude transactions on a bilateral basis or through an anonymous exchange.
Trading is continuous and dispatch decisions can be continuously
updated until a “gate closure” specified by the TSO. At gate
closure, a final dispatch schedule is notified by the generator to the
transmission system operator.
❏ Balancing actions and re-dispatch
If, on the basis of the aggregate of final notifications, the system is
out of balance or internal security limits are breached, the system
operator will require some generators to change their actual
output from the final notification amounts. This is usually based
on priced offers by generators to increase/decrease production
compared to notified amounts.
Locational issues
The production and consumption of electricity also has a locational
element. However, it could be argued that this aspect is less important for electricity than for other commodities. Depending on the
characteristics of the transmission network, it is not always necessary
to deliver electricity exactly to the point of consumption. Provided
the network is meshed enough, it is normal for most trading to be
conducted around particular “hubs”, or on a zonal basis.
❏ With a zonal market, common in Europe, the assumption is that
transmission capacity is always available to deliver the energy to
the customer, wherever it is in that zone. This often requires
“remedial actions” by system operators, such as re-dispatch
(discussed above). But, as long as these do not become too
frequent or costly, these actions can take place outside the
market without upsetting trading.
❏ The main alternative, used in North America, is a nodal market
where each node in the transmission network has a separate
116
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 117
WHOLESALE POWER MARKETS
individual price. A hub price may then develop based around a
set of nodes that usually end up with the same price, and which
are then treated as a price zone by market participants. In this
model, market participants carry the locational basis risk of
possible price changes between nodes. However, system operators also sell transmission rights between these nodes to help the
market manage these risks.
Electricity “quality”
Unlike many other products, electricity has the same “quality” for
each unit of production. One megawatt hour (MWh) is exactly the
same as another – unlike, for example, natural gas where a cubic
metre of gas might have a different calorific content. However, this
physical reality has latterly been changed by environmental considerations. Consumers and governments may now place a higher
value on units that are renewable or low carbon. This is already
starting to make the trading of electricity more complicated. For
example, under so-called “green certificate” schemes, retail suppliers
have to purchase such certificates alongside the electricity they need
in order to serve final consumers. Likewise, under other support
schemes, renewable energy might be sold in wholesale markets on a
“must-run” basis, even if prices are zero or even negative. The fact
that a section of the electricity market is asked to behave in a noncommercial manner makes it more difficult to form expectations
about spot prices and discourages forward trading.
Electricity “market design”
Overall, electricity markets are probably more complicated than
other commodity markets. This often raises the question about
whether they are, in fact, too complicated to allow for a normal standardised and commoditised set of products to develop. Electricity
markets are already not particularly liquid compared to other
commodities. If the market becomes further fragmented into
different time, location and quality characteristics, the future for
standardised trading begins to look rather uncertain.
In the meantime, these features normally mean that the wholesale
market for electricity is, to an extent, something of an abstract regulatory construction. Academic and regulatory literature often speaks
of “market design” for electricity, which is not a term commonly
117
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 118
COMMODITY INVESTING AND TRADING
used for other commodity markets. Nobody ever talks about crude
oil “market design” in a regulatory sense. Complications such as
freight costs and quality standards are left up to the market participants to sort out for themselves.
Part of the challenge in electricity market design is getting the
balance right between the role of the market and that of government
and regulators. Policymakers continue to struggle with this challenge, even in the most mature electricity markets. Indeed, there is an
observable cycle backwards and forward between more regulated
and more market-based policy frameworks.
Where can functioning wholesale markets be found?
At the time of writing, there are several functioning and reasonably
liquid wholesale markets that perform the central tasks of price
discovery, offer hedging opportunities and give signals to market
participants for efficient operational and investment decisions.
Liquid wholesale power markets exist to a greater or lesser extent in
several areas of the European Union, in parts of North and South
America, and in Australia and New Zealand. Traded electricity
markets are also coming into existence in other countries. This
chapter will concentrate on the development of wholesale power
markets in Europe, particularly in Germany and Britain (GB).
HOW POWER IS TRADED – THE CHARACTERISTICS OF
EUROPEAN ENERGY MARKETS
European market design principles: The importance of the
balancing regime
European market design is based on self-dispatch rather than
centralised dispatch of power production – unlike, for example, most
North American markets. It is therefore a bilateral two-sided market
in that generators sell into, and retailers buy from, wholesale markets.
As discussed, this means that the system operator’s role is
restricted to dealing with residual imbalances in the system as a
whole and resolving any locational constraints. This takes place after
“gate closure”, which is normally one hour before real time operation. However, in reality, system operators sometimes have to begin
to take some action before gate closure if plant expected to be used
for balancing or re-dispatch needs to be ramped up or warmed in
advance.
118
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 119
WHOLESALE POWER MARKETS
Market participants on both the generation and the retail side have
to balance at gate closure across a so-called “settlement period” of
either 30 minutes or 15 minutes. Those market participants whose
actual measured injections do not match their consumption are said
to be “out of balance” and are subject to imbalance charges. They
have to pay the system operator for the actions required to balance
the system. This payment is governed by the national regulator in the
country concerned. It is usually based on the costs to the TSO of
resolving imbalances, although the formula used varies in each
country. Balancing arrangements are increasingly market-based,
with the settlement price based on bids and offers from those generators with spare capacity, or alternatively demand-side offers.
An important consequence of this market design is that trading of
electricity and also price formation is strongly driven by the desire of
market participants to avoid the consequences of being out of
balance. If a company goes into gate closure with a short position,
they are potentially exposed to very high imbalance prices at particular times. Likewise, being long at gate closure is not without risks
either, particularly if imbalance prices can go negative, which is a
possible outcome. The balancing mechanism is therefore at the heart
of European market design.
Day ahead and intraday markets
The other main reference price in European markets comes from the
“day-ahead markets”. These are largely two-sided cleared auctions
operated by dedicated market operators. For example, in Germany
and France the auction is run by EPEX Spot (a joint venture between
EEX and Powernext). Meanwhile, day-ahead auctions in GB and in
Nordic markets are operated by Nord Pool Spot. The Dutch dayahead auction is operated by APX-ENDEX (now a subsidiary of
ICE), who also operates a day-ahead market in GB.
Day-ahead exchanges are not usually compulsory marketplaces.
However, there is a strong regulatory push to ensure these markets
are liquid. In the draft European network code on capacity allocation
and congestion management (CACM), it is envisaged that these dayahead exchanges will play a central role in allocation of cross-border
transmission capacity. This process is known as market coupling.
The CACM network code was slated to become binding European
legislation in 2014.
119
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 120
COMMODITY INVESTING AND TRADING
As well as the day-ahead markets, there are various platforms for
intraday trading. Unlike day-ahead, which is almost exclusively an
exchange-based auction, trading in the intraday can either be
exchange-based or a bilateral over-the-counter (OTC) market. This
often depends on the historical development of markets and regulatory attitudes. For example, in the Nordic countries intraday trading
is exclusively via the Elbas platform, which is provided by Nord
Pool, whereas the system used in Germany is a platform that allows
both exchange-based trading and bilateral exchanges.
Forward markets
Physical versus financial
However, the day-ahead and intraday phases are only for finetuning positions. The vast majority of electricity is traded long before
this point on a wide range of forward markets of different types.
Forward products may be either physical or financial. Financial
trading are contracts for difference that are based around a dayahead reference price. With financial trading, a strike price is agreed
(eg, €40/MWh). If the day-ahead price is above this – for example,
€45 – then the buy-side counterparty will buy their power in the dayahead market and the seller of the forward product will pay them the
€5 difference. The buyer does not take on any obligations with
respect to balancing and nomination, as discussed earlier.
Physical contracts are used when both parties are already responsible for balance. Then the transaction is an obligation on the selling
party to physically deliver the amount sold or else face the imbalance
charges on behalf of the buyer.
Brokers such as Trayport and Spectron offer a screen-based broker
service based on physical delivery. Other products, such as those
offered by EEX, APX-ENDEX or Nasdaq, are financial trades based
on contracts based on the day-ahead prices. Voice-activated trading
is also possible.
Forward market products
There is a range of possible products for forward trading. The most
liquid market is for baseload power, meaning a flat amount of power
over a 24-hr period. Baseload power can be traded weekly, monthly,
quarterly, by seasons or annually. Trading may be either exchangebased and cleared, or through bilateral OTC transactions. Trading in
120
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 121
WHOLESALE POWER MARKETS
seasonal and annual baseload products usually goes out to 2–3 years
into the future for both financial and physical settlement.
The other main product traded forward is peakload. This refers to
the period of 0700–2300 each day. Again there is a range of forward
peakload products available. However, the forward curve is not as
liquid as for baseload. Products are usually only available for 1–2
years in advance of real time.
Finally, it is also possible to trade four-hour blocks in some
European markets, such as in the GB market. However, these are
usually not available until some days/weeks before real time.
Spark and dark spreads
The final complication to mention is that trading in baseload products, in particular, is largely on the basis of “spreads”. For example,
the “spark spread” is the difference between the electricity price and
the cost of producing that electricity from a certain standard efficiency gas-fired power plant, based on the prevailing gas prices. The
“dark spread” is the same concept for coal. With the advent of carbon
trading, indexes for “clean spark spread” and “clean dark spread”
were developed which are popular forward products, particularly in
the GB market where both coal and gas have liquid reference prices.
HEDGING STRATEGIES AND PRICE FORMATION
Market participants will usually have some pre-specified procedures
about how they interact with wholesale markets. This will partly be
driven by the company’s risk controls. No company will wish to take
or maintain a position that will leave it too exposed to a disadvantageous movement in prices. In particular, taking on large exposed
positions requires the company to allocate risk capital to trading
activity that is earmarked to cover possible adverse price movements. In addition, accounting rules, specifically the International
Financial Reporting Standards (IFRS), may also discourage companies from taking large positions since these have to be “marked to
market” in a company’s account. This can result in a potentially large
impact on the company P&L, with undesirable knock-on effects on
credit rating and market sentiment.
In general, the expectation is that retailers hedge the bulk of their
positions in advance through trading of baseload and peakload
products. They will then use the short-term markets for fine-tuning
121
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 122
COMMODITY INVESTING AND TRADING
their exposures. They may have some kind of target “hedge path” in
terms of what proportion of their consumers’ needs should be
covered by a certain date – eg, that X% should be bought by Y
months before consumption.
Likewise, generators will also sell the bulk of their generation
capabilities in forward markets in order to allow for effective business management. For example, the generation business will need to
know in advance how much revenue they are likely to collect in a
particular year. They will then be able to decide on a maintenance
timetable and other budgeting decisions. However, they will not
necessarily sell all potential volumes into forward markets since this
implies a risk in the event of a generation failure.
In essence, price formation in forward markets, and therefore
customers’ bills, is the consequence of how these decisions are taken
about how, and when, to buy and sell. For example, the more that the
supply–demand position is expected to be tight, the more that
retailers will tend to try and manage their exposure to short-term
markets and seek to hedge earlier, pushing up forward prices.
Conversely, if there is expected to be large margins of spare generation capacity, retailers may be more content to delay buying volumes
and wait for prices to fall. Similarly, generators may have to accept
selling at lower spreads if they see a lot of spare generation capacity
around and there is little prospect of prices increasing in spot markets.
HISTORICAL PRICE PERSPECTIVE
Germany
Figures 5.1 and 5.2 show the main trends in electricity prices in
Germany. The German electricity market is the most liquid in
Europe, if not the world. Trading is based on a single Germany/
Austria day-ahead reference price.
Initially, market opening between 2000 and 2005 led to significant
reductions in wholesale market prices as more competition was
introduced and trading became established. Prices gradually
increased between 2005 and 2008, bringing considerable new investment in generation. Some 10GW of new conventional plant began
operation in the period 2010–13. However, the financial crisis and
reductions in industrial demand have bought about significant price
reductions. This was only partly reversed by the enforced closure of
all German nuclear plants in 2011 after the Fukushima disaster.

The other important feature in the German market is the
combined impact of increased renewable production and energy
efficiency initiatives. From 2010, renewable production started to
have a profound impact on the market mainly due to the sheer scale
123
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 124
COMMODITY INVESTING AND TRADING
of investment in this sector. Take-up of renewables has been rapid as
producers benefit from a guaranteed feed-in-tariff. Compared to
peak consumption of around 80GW, there is now some 30GW of
wind production. Meanwhile, solar photovoltaics capacity increased
from 10GW in 2010 to 30GW in 2012. In Germany, renewable
producers do not themselves sell their own production. Neither do
they have to balance their portfolios like other market participants.
Instead, the TSOs have to accommodate all renewable production,
which they themselves sell on day-ahead and intraday markets. This
is known as “priority dispatch”. The high installed capacity of
renewables means there are now frequent incidences where most, or
all, of electricity consumption is served by renewable production.
Understandably, this affects price formation on both spot and
forward markets. Spark spreads have become particularly weak and
have been negative since the start of 2012. The impact has been
particularly strong on peakload prices, with the difference between
baseload and peakload prices narrowing. This is because normal
peak periods have been offset by high levels of solar production
during the afternoon period in some parts of the year. In general, as
renewable penetration continues to increase, the classic baseload and
peakload products may begin to lose their relevance and alternative
products may need to emerge in order for the market to fulfil its
functions effectively.
To an extent, periods with high renewable production can be
offset by imports and exports of power to neighbouring countries.
Since 2009, Germany has participated in the central–western Europe
(CWE) Market Coupling project. This uses the day-ahead power
exchanges to allocate cross-border capacity such that power automatically flows from low prices areas to higher priced areas. This
may help the transition of markets to the high renewables world.
Great Britain
Figures 5.3 and 5.4 illustrate similar data for the GB market. As for
Germany, there is a single price zone that covers all of the island of
Great Britain.
GB prices have followed a fairly similar pattern to those in
Germany. The fall in demand in GB was, if anything, more
pronounced than in Germany with an abrupt negative effect on clean
spark spreads. Capacity margins are such that forward prices at the

time of writing do not show much sign of recovery despite the anticipated closure of some 10–15GW of generation capacity up to around
2017.
Renewable production has not yet reached the same level of penetration as in Germany and its impact will continue to grow.
However, a key difference in the GB market is that renewable
producers are, and will continue to be, responsible for selling their
own power and, other than the smallest facilities, are balanceresponsible. This may prevent the impact on prices being of the same
magnitude. The subsidies for solar production and the extent of takeup, in particular, are markedly less generous.
Compared to total peak demand of some 60GW, there is around
12GW of renewable production, a much lower percentage than in
Germany. Only around 1GW of solar photovoltaics has so far been
installed in the GB market.
Wider relationships between European markets
European markets are becoming increasingly correlated, especially
as interconnection between EU countries increases and the existing
infrastructure is managed more efficiently via market coupling.
However, there are still major locational issues and associated basis
risk that affects them.
The main locational features of European power supply is that,
due to hydroelectricity resources, the Nordic countries usually have
a year-round surplus of generation (unless there is a very cold
winter, preceded by very dry conditions). This often leads to
comparatively low wholesale prices in the Nordic system.
Both France and Belgium have high shares of nuclear power and
these countries have traditionally had low wholesale prices.
However, the high level of peak heating demand increasingly means
that these countries now import in the winter. During 2009–12, the
price differential between Germany and France closed and has
reversed to an extent that in France, prices are higher than those in
Germany. Both GB and the Netherlands electricity prices are typically driven by gas prices, and a locational spread with Germany will
emerge if gas and coal prices deviate. Italy has typically had the
highest wholesale electricity prices in the EU.
Differences between these regions are maintained as a consequence of constraints in the overall European transmission network.
126
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 127
WHOLESALE POWER MARKETS
Generally speaking, the construction of new transmission assets is
very slow as a consequence of local resistance to new lines being
built. The main problems are objections to the visible appearance of
new transmission lines. Transmission assets are normally
constructed on a regulated basis, although there have been a few
sub-sea merchant interconnectors, such as Britned (between GB and
the Netherlands).
At the same time, the local supply–demand balance also tends to
move rather slowly as new generation assets are added and others
close. Overall, the extent of price differences between European
regions has tended to reduce slightly over time.
New developments
Power prices are increasingly driven by regulatory interventions, in
particular the objective of European Union countries to extend
renewables and to decarbonise. As already noted, the significance of
the traditional baseload and peakload divisions of wholesale products is beginning to be questioned. Locational issues are also
becoming more complex as there will no longer be price areas that
have low or high prices throughout the years or seasons. Instead, the
variations will tend to be increasingly seen in short-term markets.
Another regulatory development may come from possible
changes to the price zones. At the time of writing, the EU is developing network codes that will embed the methods of market
coupling that have already been in use for some time. Part of this
discussion, however, is about whether the price zones as of 2013,
mainly based on national borders, accurately reflect the real transmission constraints in the network. This raises the prospect of price
zones being split, or indeed merged, in the future. This may affect
how basis spreads between different zones develop. If the price
zones more closely matched transmission constraints then the basis
spreads between zones would probably be larger and more stable.
A final important locational issue may arise from the introduction
of flow-based market coupling. This model better takes into account
the inter-relationships between use of capacity on different interconnectors in the meshed European networks. For example,
suppose there are three price areas: A, B and C. In reality, the
capacity available between area B–C is affected by how much electricity is flowing between A and B and between A and C. A
127
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 128
COMMODITY INVESTING AND TRADING
flow-based approach explicitly takes these interactions into account.
With a non-flow-based approach these relationships are not
captured and the available transmission capacity between each area
is set independently.
The flow-based model will, in all likelihood, tend to make the
envelope of interconnection capacity larger. On the other hand, it
may be more difficult for market participants to understand the price
formation process and make it more difficult to formulate a trading
strategy.
KEY ISSUES FOR THE COMING DECADE
Evolving market design
The main issues for the coming decade are mainly regulatory rather
than purely economic. In particular, the increase in renewable
production will be the main challenge for the market between 2013
and 2020. First, it creates long-term uncertainty, beyond the trading
horizon, about what level of renewables penetration will occur. In
addition, the way in which renewable production is activated and
sold into the market also brings short-term issues.
Under priority dispatch schemes, as in Germany, the renewable
power tends to be sold into day-ahead and intraday markets by the
system operator rather than being spread over forward markets.
This creates unnecessary volatility and uncertainty. There are some
moves towards removing priority dispatch rules and asking renewable producers to sell their own production into the wholesale
market. This is expected to introduce more commercially oriented
trading strategies that will be more predictable and stable.
Meanwhile, in the GB market things are moving in the opposite
direction. Under the proposed contract for difference (CFD) scheme,
renewable producers will be compensated for the difference between
the day-ahead price and a negotiated fixed “strike price”. So,
although renewable producers will be required to sell their own
power, the linkage of the CFD to the day-ahead price may again
mean that plant is not being optimised in a predictable commercial
way.
Other regulatory developments include the intention, in many EU
member states, to introduce capacity mechanisms. This is part of the
policy response to the uncertainty created around the extent of
renewables and other low-carbon penetration. However, these inter128
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 129
WHOLESALE POWER MARKETS
ventions will inevitably have an impact on power prices. They will
also introduce a further set of regulatory uncertainties that will make
developing a trading strategy more challenging, and this is likely to
reduce the liquidity of forward markets.
Finally, as volatility moves from the forward markets to more
short-term markets, different traded products may increase in
significance. Option products are a market-driven way to reward
capacity and flexibility. There may, therefore, be greater use of
options to allow portfolios of intermittent generation to be managed
effectively. Of course, this will only happen if renewable producers
are responsible for their own portfolios and if a voluntary option
market is not undermined by regulatory interventions. Some
designs of capacity market such as the “reliability options” model
used in North America are effectively a compulsory, centralised
option market.
Financial market regulation
Financial regulation is also set to have an impact on the format of
trading. The EU regulation on OTC derivatives, central counterparties and trade repositories (EMIR) came into force on August 16,
2012. It includes a requirement to centrally clear transactions once a
company’s portfolio exceeds a certain threshold of €3 billion. Many
large energy trading houses may be captured by this and, if so, there
will be an increase in the amount of cleared transactions as a result.
Discussions on the exact requirements were ongoing throughout
2012–13 via the “Draft Technical Standards”. These were produced
by the European Securities and Markets Authority (ESMA) and,
following the scrutiny of the European Parliament that concluded in
February 2013, they were to be adopted by the Commission as
binding requirements via the Comitology process and phased in
over three years: 2013–16.
In addition, discussions were ongoing during 2013 about new
versions of the Markets in Financial Instruments Directive (MiFID).
The old directive will be replaced by MiFID2 and a regulation
(MiFIR). One possible outcome is that trading houses above a certain
size will be regulated in the same way as banks, complete with strict
capital requirements. However, there are possible exemptions that
are being discussed, including the ring-fencing of some physical
trades when determining whether companies exceed the threshold.
129
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 130
COMMODITY INVESTING AND TRADING
MiFID is also expected to set requirements on companies regarding
position limits and risk management techniques.
Many of the proposals put forward in the EU context are already
part of the legislation in the US, via the Dodd–Frank Act. Traders will
have to get used to compliance with this type of regulation.
However, all these tend to add transaction costs and potentially
reduce the liquidity of wholesale markets. Other interventions have
been regularly floated, such as the Financial Transaction Tax or
sporadic restrictions on short-selling. These could have a similar
negative impact on traded markets.
Changing consumer requirements – more bespoke services?
Other more consumer-driven factors are also relevant. The spread of
small-scale renewable generation may tend to move the market
away from more centralised solutions, and in the direction of more
localised and bespoke solutions. New technologies such as electricity
storage may also be more easily developed on a small scale. This will
mean that the traditional relationships between producers and
consumers will become blurred so that they become amalgamated
into one role. So-called “prosumers” may become much more usual.
Again this may make a centralised traded market less important. On
the other hand, the development of alternative, innovative traded
products may still preserve the role of the classic trading function.
SOURCES OF MARKET INFORMATION
There is a wide range of sources of information on European
markets. In 2005, the European Commission established the Energy
Market Observatory, which now produces regular reports on price
developments, investment, etc. The transmission system operators
(via the European Network of Transmission System Operators,
ENTSO) also provide information on interconnector availability and
regular assessment and projections of the supply–demand position.
The Regulation on Energy Market Integrity and Transparency
(REMIT) came into force in 2011, which requires all electricity and
gas companies to publish any inside information that they hold. In
effect, this means provision of data on all planned and unplanned
outages, projected return to service dates and metered production
volumes of all power plants above a certain size.
It is expected that REMIT will be strengthened during 2013 with
130
05 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:47 Page 131
WHOLESALE POWER MARKETS
the introduction of more specific binding guidelines on transparency
from the European Commission. This will apply to generators, transmission system operators and large consumers. The likelihood is that
this will lead to a centralised platform for reporting information. At
present, companies are largely reporting inside information on their
own individual websites.
CONCLUSIONS
The main questions about power markets in Europe are well known.
Where are prices and spreads going? What will the market look like
in 2020 and beyond? Will there even be a market that we recognise?
The first question is difficult to answer. Prices and spreads are
low, and this is mostly due to an unexpected event: the financial
crisis and its impact on the economy and electricity demand. So,
although at the time of writing there does not seem much prospect of
recovery, we do not yet know what other unexpected events might
occur. However, we do know that prices for the traditional baseload
product are likely to be continually eroded by more renewable penetration. Meanwhile, flexibility should become more valuable, so we
might end up in a situation where one type of traded product
continues to experience falling prices, while prices are rising in
another segment of the market.
The market in 2020 will clearly look somewhat different. More
complex and bespoke products may develop, which may or may not
have the same liquidity as the traditional ones. Trading might also
continue to move towards the short term as it becomes more and
more difficult to take a position on how things will look beyond one
or two years. This may feed through into the relationships between
the market and consumers. Supply contracts to end-users based on
long-term contracts may also become prohibitively expensive in
view of the additional risks and uncertainties.
Will the traded market exist at all? There is clearly some risk that
the panoply of regulatory interventions will drive liquidity out of
wholesale markets entirely. Contractual structures may then become
more bespoke and possibly also have a high degree of regulatory
involvement. More integrated solutions may become more popular
and this will move us away from traded outcomes.

The Metals Markets
Kamal Naqvi
Credit Suisse
In this chapter, we will examine the key determining factors for
metal price analysis: physical demand, supply and inventory. We
will then explore how these three factors combined lead to price
formation, together with a short discussion of a range of other influences – such as currency, speculative and investor flows or
positioning, and inflation. Across the metals complex, it should be
apparent by the end of this chapter that the importance of these
various factors varies significantly from metal to metal. We finally
conclude with a short discussion regarding the major differences
between the three metal segments, with a summary of the individual
fundamentals and trends in these markets.
For the purposes of this chapter, we shall define the metals
markets, also known as basic materials or industrial minerals, as
mined commodities that have a recognised and liquid global paper
trading market that is widely used as the primary pricing mechanism for that commodity. The metals markets, under this definition,
can be split into three areas: base metals, bulk commodities and
precious metals. However, for much of this chapter we shall refer to
the entire group as “metals”.
The metal markets are, arguably, the most direct expression of
applied macro and microeconomics. The core driver of demand for
almost all metals is industrial production, on a country, regional and
world basis. However, there are micro differences for individual
metals demand and these can be very important for idiosyncratic
pricing. The nature of global metal supply tends to be relatively
133
06 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:53 Page 134
COMMODITY INVESTING AND TRADING
stable with, typically, only modest seasonality compared to, say,
agriculture. The meeting of demand and supply then is the stock and
flow of inventory, which is the main underpinning for metal prices.
The global metals markets are one of the longest serving
commodity trading markets. Used as a currency at various points of
history across the world, the metals markets are now best understood
as, arguably, the purest form of global commodity market due to their
homogeneity. Unlike most agriculture and energy markets, the metal
markets tend to have largely standardised physical properties and are
less specific to regions or countries. Hence, metal prices tend to reflect
the interaction between global supply, demand and inventories.
INVENTORY
As they are relatively easily stored, inventories for metals tend to be
more visible and therefore quantifiable compared to other commodities. The key to fundamentally driven commodity pricing is the
relationship between inventories and price. For most of the metals
(gold is perhaps an exception), this is a normal relationship – with
declining inventories typically associated with upward price pressure. This is shown in Figure 6.1.
The two key elements for pricing dynamics are:
❏ the level of inventories, measured best in terms of how many
days, weeks, months or years of consumption; and
❏ the rate of change in inventory levels.
These two factors combine to form the physical fundamental drivers
for metal prices. A very low level of available inventories, such as
copper or tin (as noted in Table 6.1), will typically see high and
volatile prices as in this situation only modest changes in the
supply/demand balance are needed to produce a large change in
prices. In contrast, metals with very large levels of inventories, such
as gold and silver in Table 6.1, require much larger changes in the
supply/demand balance to justify a change to price.
It should be noted that the “weeks of consumption” heading in
isolation means little for relative pricing, but is shown for illustration
of relative availability of metal inventories. The price for an individual metal depends more on the relative level of inventory
compared to its own history.

Inventory levels are not only the primary driver for price levels
and change, but also for forward pricing, which will be discussed
later in the chapter.
DEMAND
Metals demand is strongly linked to economic growth. However,
while the level of global GDP is a reasonable proxy for living stan135
06 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:53 Page 136
COMMODITY INVESTING AND TRADING
dards and can be a useful broad macroeconomic variable for the
energy and agricultural markets, it is not such a useful representation for industrial materials demand, as a large share of GDP is
related to the services sector in most developed economies. Rather,
the best macroeconomic drivers of industrial materials demand are
industrial production (IP) and real fixed asset investment (FAI), as
shown in Figure 6.2.
There are, of course, micro differences between the metals markets
in terms of sensitivity to these broad macro variables, depending on
which sectors and countries dominate their use (see later in the
chapter), but they are relatively modest compared to the primary
trend.
On a national level, for industrial materials one country has
become dominant: China. As shown in the Figures 6.3 and 6.4,
Chinese demand for almost all metals has become dominant in
absolute terms and even more so as a proportion of global demand
growth. For this reason, much of the traditional analysis of demand
by country has been overwhelmed by the flows in Chinese demand,
particularly as represented by Chinese trade data.
SUPPLY
Metals supply originates from mined ore that is then processed into
standardised physical properties to allow for global sale. The various

a variety of extracted and processed minerals. Iron ore and coal are
concentrated ores and require only relatively modest processing to

metals from concentrate, while aluminium and the precious metals
require further elaborate processing to meet global standards.

Scrap can also be a meaningful source of annual supply for some
metals, such as lead and the precious metals.
Long lead times for new mines tend to lead to longer price cycles
for many metals. In Figure 6.5, copper mine production can be seen
to have grown only modestly from 2004 to 2012, despite a massive
increase in copper prices. This is due to the lagged response of mine
supply to price.
The cost of supply is the other supply-side factor that supports
prices. Figure 6.6 depicts the industry cost curve for aluminium in
2012, and this can be used as an indication of sustainable prices in the
medium term. However, this support level is not a stationary one as
most elements of mine supply costs – such as labour, power, equipment and energy – are also cyclical.
Using copper as an example, Figure 6.7 illustrates the drivers of
mined supply costs and also highlights the sharp escalation in costs
in copper mine supply since 2005. In money-of-the-day terms, mine
site cash costs have doubled, largely due to steep increases in the unit
costs of labour (direct wages), service provision (essentially a form of
labour) and consumables. Energy costs have also risen, but for
copper mines these are a smaller proportion of costs than, say,
aluminium production.

PRICES
As discussed earlier, the key to fundamentally driven commodity
pricing is the relationship between inventories and price. The actual
or estimated level of inventories, best measured in terms of
consumption, and the expected change in inventories, known as the
market balance, are the core drivers for the price level, the volatility
of prices and the shape of the forward price curve.
The metals markets tend to have long price cycles due to the long
lead times in mined supply. Figure 6.8 depicts a long-term time

series for base metals showing how long the price cycle tends to be
and also, interestingly, that current prices for base metals are not
significantly high in real terms. This is despite the fact that since 2002,
the prices of all metals have risen significantly, with gold and iron
ore reaching all time highs in 2012, as shown in Figure 6.9.
The rise of electronic access to commodity markets and growth in
high-speed trading technology has, in our view, changed short-term
commodity pricing dynamics – not necessarily for the better or
worse, just changed. A standard technical analysis for copper, for
instance, has become a new challenge for traditional commodity

market participants, including (perhaps even especially) specialist
commodity hedge funds. A paper on this topic (Filimonov, V., D.
Bicchetti, N. Maystre and D. Sornette, 2013, “Quantification of the
High Level of Endogeneity and of Structural Regime Shifts in
Commodity Markets”, SSRN) concluded that there is evidence of
greater price endogeneity rather than external news/factors. Other
markets have gone through the same evolution, and the metals
market is no different. It does not mean the physical commodity
fundamentals have become irrelevant – indeed, return dispersion
suggests the opposite – it simply means that there are a few more
variables added to the market.
Macro factors have latterly become a more important driver of, or
rationalisation for, metal prices. The two factors that have endured
the cycles as being an influence on metals prices, or being influenced
by metal prices, are currencies and inflation.
Figure 6.10 shows a long-run series of copper prices in a variety of
currencies; it is notable that for key cycles the price experience can
diverge significantly. This is relevant to metal price formation, as a
weak domestic currency is a positive for producers and a negative
for consumers, with the oppositive also being the case.
The link between metal prices and inflation is more muted for
most metals, with the clear exception for gold. For many reasons,
gold is an exception to the price formation basis for the majority of
the metals markets. It has often been seen as a long-term preserver of

wealth and, therefore, a hedge against inflation. Certainly it is true
that, at times, gold prices can be highly correlated with inflation
expectations (see Figures 6.11 and 6.12).
The bulk of this chapter has discussed spot or front price formation, which is the prime focus for metals market analysis as it
determines the demand for physical metal for immediate delivery –

THE METALS MARKETS
from which all market price points are determined. However, when
trading the metals markets, much discussion revolves around the
point of the forward price curve that needs to be traded and to what
degree that point does or does not reflect the expectations already
“priced-in” to the market.
For example, in Figure 6.13, the iron ore market curve changed
significantly in both shape and level over several months reflecting
how changes in market expectations, the demand from physical
consumers for immediate delivery of metal and the flow of business
across the various points of the curve can shift and reshape the
forward prices.
Commodities with relatively low levels of available inventory
tend to be in backwardation, with nearer-dated futures contracts at
higher prices than the futures contracts further out the curve,
reflecting the premium that the consumer is willing to pay to secure
metal. If the contrary is true, and the market is perceived to be in
ample or over-supply, then the futures curve tends to be upward
sloping, and the market is said to be in contango.
Metals tend to have a somewhat more consistent contango
compared to energy due to the relative ease of storing metals. Gold is
the extreme example of this, with storage of gold being a tiny fraction
of its cost and, therefore, gold tends to trade in perpetual contango

with forward prices driven by the US interest rates minus the storage
or leasing rate. For other metals, such as aluminium, there is also a
tendency towards contango as inventory tends to be built and held
for large consumers, such as car manufacturers. Operators with their
own storage facilities and/or access to cheaper finance can sometimes buy and hold physical metal against an offsetting paper
position for a (largely) risk-free return.
BASE METALS
The base metals, also known as industrial metals or non-ferrous
metals, are aluminium, copper, zinc, lead, nickel and tin. The world’s
benchmark contracts are listed on the London Metal Exchange
(LME). However, other key contacts include the Comex Copper and
Shanghai Futures Exchange (SHFE) copper contracts.
The LME has an idiosyncratic trading system. The most active
daily price is known as the “three months price”, literally a trading

date which is three months forward of the current day, subject to it
being an official trading day (ie, not a UK holiday). Future points on
the forward curve are then traded as a spread to the three months
price. Figure 6.14 shows the structure of LME futures dates, daily out
to three months, weekly to six months and monthly out to 10 years
for some products.
The LME also remains one of the few remaining open outcry
trading markets where the official daily prices are set by the clearing
price found across the floor, as it is known. Commercial players
(mining companies, industrial users, physical merchants, endconsumers), banks, brokers, hedge funds, and institutional investors
are all active participants.
Most of the discussion in the chapter so far applies to the base
metals markets in terms of market analysis and price formation. We
shall now contrast the bulk commodities and precious metals
markets.
We provide a chart and table summary of the main features of the
base metals markets in Figures 6.15–6.18 found at the end of this
chapter.
BULK COMMODITIES
For the purpose of this chapter, we limit our definition of the bulk
commodities to the mined materials of iron ore and thermal coal
(note that others may include steel and freight within the definition).
The bulk commodities are so-called due to the sheer physical
volume of production. Both iron ore and coal production are more
than the combined output of the six LME metals. However, unlike
these metals, the majority of global production of both iron ore and
thermal coal is used domestically, with the balance often being
shipped long distances to consumers. Both materials have a dominant usage, with iron ore being the key ingredient for steel and
thermal coal for energy.
Historically, both iron ore and thermal coal were supplied on a
contractual basis (typically, annually), based on periodic negotiations between producers and consumers. However, since the early
2000s, both markets have moved away from this structure towards a
physical spot market supported by an over-the-counter (OTC) paper
forward market. Latterly, clearing of OTC swaps and even futures
exchange markets have emerged. The OTC markets are priced
145
06 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:53 Page 146
COMMODITY INVESTING AND TRADING
against industry benchmark indexes that are based upon spot physical deliveries.
Due to the magnitude of the flow and the relative high costs of
freight as a percentage of the final price, both iron ore and thermal
coal can be quoted by including the cost of freight to the consumer
port price (CFR). This is typical for iron ore, or from the port of the
producing country before the freight on board (FOB) price, which
tends to be more common for thermal coal.
PRECIOUS METALS
Precious metals, particularly gold, are among the most actively
traded commodity markets, with gold having the widest number of
trading participants of any commodity, including oil. The precious
metals that are actively traded are gold, silver, platinum and palladium. All of these have liquid OTC and exchange-traded markets.
Unlike other commodities, they also have a very large physically
traded wholesale market, of which London is generally seen as the
global centre, although there is a wide range of important local
markets across the world.
The term “precious” relates partly to their relative scarcity and
partly as they are often used as a store of value rather than for direct
consumption – although both gold and silver are commonly used as
miniature decorations on top of Indian sweets, and hence are
genuinely consumed! The precious metals markets are also distinctive in having traditional banking elements – that is, gold can be
deposited, on an allocated or unallocated basis, and therefore also
borrowed or leased, much like classic money.
The precious metals, and particularly gold, have probably more
trading centres than any other commodity, despite being globally
homogenous. As mentioned, while the global central point for the
precious metals market remains London, there are a wide range of
very important physical gold markets, including Zurich, Mumbai
and Dubai. However, increased market share and overall liquidity
lies in the listed exchanges, in particular the New York Mercantile
Exchange (Nymex), the Shanghai Futures Exchange (SHFE), the
Multi Commodity Exchange (MCX), the Tokyo Commodity
Exchange (TOCOM) and the Dubai Mercantile Exchange (DME).
Unlike other commodities, a large fraction of all the precious
metals mined in history still exist and can be considered, at least
146
06 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:53 Page 147
THE METALS MARKETS
theoretically, to be above-ground inventory. This is not so much the
case in silver, and even less in platinum and palladium, which is why
they are more similar to the base metals markets.
Furthermore, precious metals, and particularly gold, used as a
central bank asset in bar form means that there is also an active and
liquid lease or borrowing market, which reduces the scope for physical scarcity to influence the price – although occasionally certain
bars or coins may trade at a higher premium due to their individual
scarcity. Instead, market sentiment tends to dominate precious
metals prices and this can be influenced by many differing elements,
of which physical supply and demand is just one; others include
inflation, currencies, geopolitics and uncertainty or risk more generally. The jewellery sector is important for all the precious metals
markets, while industrial usage is also important for silver, platinum
and palladium.
Physical investor demand is also a key factor, with increased
accessibility through exchange-traded funds having become a major
market influence and now also a major inventory.
CONCLUSIONS
The chapter was primarily designed to provide an initial guide to
analysing the basic material of metal markets. It should hopefully
have become clear that while there are overarching similarities to the
group, specific analysis requires a quite idiosyncratic approach to
not only each market’s supply, demand and inventory, but also to its
relationship to other commodities, particularly other metals, as well
as wider macro relationships. In reality, each individual market
could have an entire book dedicated to its analysis.
The global metals markets are at a pivotal time. Since the early
2000s, prices have often been gripped in the so-called “super-cycle”.
Definitions vary on what “super-cycle” means, but for some it is
higher than average real or nominal prices. Under such a definition,
we think this will continue. However, for most it means synchronous
rising metal prices, and this we do not think will occur. The true
super-cycle, from 2002 to 2007, was buoyed by a range of synchronised, positive physical and financial factors that combined to drive
prices to historical nominal highs.
In summary, the physical factors driving the metals markets are
shown below.
147
06 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:53 Page 148
COMMODITY INVESTING AND TRADING
❏ Demand surge:
❍ Chinese;
❍ emerging markets; and
❍ moderate growth across the rest of the world.
❏ Supply constraints and costs explosion:
❍ falling ore grades;
❍ labour shortages and disruption;
❍ technical problems (mines and refineries);
❍ infrastructure bottlenecks, delays and disruptions;
❍ resource nationalisation;
❍ environmental and social legislation;
❍ reduced availability of scrap; and
❍ shift to underground mining.
❏ Inventory declines:
❍ falling visible exchange inventories; and
❍ off-exchange inventories either falling or not being made
available.
❏ Investor buying:
❍ Investor buying:
❍ index inflows;
❍ structured product buying; and
❍ exchange-traded product demand (ETFs, etc).
❏ Hedge fund buying:
❍ commodity specialist fund buying on constructive S&D;
❍ macro hedge funds buying on a China play and/or US dollar
weakness; and
❍ technical traders buying due to signals and momentum.
❏ Corporate flows:
❍ consumer forward buying due to concerns over price rises;
and
❍ producer reductions of existing hedge books – ie, net buying.
Looking forward, many of these factors are, or are likely to be,
much less positive; indeed, they may become negative influences on
price over the next few years. Generally, we still expect nominal and
real prices to hold in a higher range compared to history, but we also
expect to see greater variation in individual metals. The winners are
likely to be those where we see little likelihood of sustained increases
in supply – such as zinc, lead, platinum, palladium and copper.

Grains and Oilseeds
David Stack
Agrimax
Grains and oilseeds were the first commodities, the staple of our diet
and the basic building blocks for meat and fish (through aquaculture).
In developed economies, food represents some 10% of GDP, higher in
developing economies. Around 20% of people around the world
receive government-subsidised food. This chapter will examine these
crops for each of the major producers and consumers around the
world, analysing how the meat and fish protein markets impact
grains, and the world’s ability to rotate and adjust crop plantings in
the face of a changing demand profile. Likely trends are also noted.
Once the domain of the big grain companies, these commodities
have been a major asset class for investors since the early 2000s, and
this chapter will take a bottom-up approach to analysing the most
relevant information for the various investment themes and their critical drivers for the years ahead. The traditional power players in the
agricultural markets, both originators and exporters, are the US, the
EU, Brazil and Argentina, and this dominance has been dramatically
affected by the increasing importance in price formation of nontraditional spheres of influence. Investment themes here have been
greatly influenced by a number of factors, such as the emergence of
China as the world’s largest grain economy – while US grain
consumption as ethanol has made it a significantly less important
player for global grains – biofuels in general, urbanisation and its
attendant social changes, dramatic changes in food consumption and
rapidly changing agricultural and environmental policy around the
globe.
Surprises that have led to a tightness in these markets include the
165
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 166
COMMODITY INVESTING AND TRADING
disappointment of genetic modification (GM) to deliver on its
promise of dramatically improving yields, the slow growth of supply
versus the expected marginal supply curve and the high rate of expansion of China’s soya demand. There have been the usual droughts,
food scares and a heightened sensitivity to food price inflation, as well
as the global economic crisis and Arab Spring that affected all
investors and markets. However, a number of important players have
entered the agricultural markets. Land investment has become a
mainstream activity, with some spectacular successes and many failures. The markets evolved from talking about speculation and land
grabs to dividing the new investors into multiple investment styles (as
many as 10, see Appendix 7.1). Some have embraced the traditional,
fundamental style of the agricultural markets, while others introduced new methodologies. Finally, the Dalian Commodity Exchange
became the second-largest futures market in the world, forever
changing the role and dominance of the Chicago Board of Trade
(CBOT). Uniquely, we will examine non-US grain and oilseed
economies; the US is already data-rich and over-analysed, at a time
when its importance in the global grains markets is declining. We look
at the evolution of the Chinese oilseed industry to a staggering 125
million metric tonnes (MMT), far bigger than the US.
This chapter will present an in-depth look at key developments
around the world since the early 1990s, in particular:
❏ the soybean rally of 2003, a surprise for everyone;
❏ the wheat rally of 2007, from sizzling problems to market explosion; and
❏ the maize rally of the 2000s, and the US corn supply/demand net
of ethanol (EtOH).
Finally, we will draw from past market developments to define the
main issues and opportunities for the forward-looking investor.
FEEDGRAINS, FOODGRAINS AND VEGETABLE PROTEINS:
THREE MARKETS, THEIR INDIVIDUAL ECONOMIES AND
INTERDEPENDENCE
The dynamic of these markets lies within the fundamentals, and this
remains the key to understanding them. By first examining the
trends for each of these three markets, and their major producers and
consumers in terms of both the switchable and non-switchable
166
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 167
GRAINS AND OILSEEDS
demand and economic drivers, we can then progress to the role of
rotation in their convergence.
The world harvests 2,525 MMT of major grains (corn, sorghum,
barley, wheat, rice, soybeans, rapeseed and sunseed – See Table 7.1)
on 800 million hectares (MHas) of land. Across the major producing
countries, the land is devoted as follows: 79% grains (27% maize, 6%
sorghum, 8% barley, 35% wheat and 25% rice) and 21% softseeds
(64% soybeans, 21% rapeseed and 15% sunseed). The average yield is
3.20 MT, of which grains average 3.40 MT and softseeds average 2.20
MT. By crop, the global averages are maize 5.00, sorghum 1.50,
barley 2.63, wheat 3.00, rice 2.88, soybeans 2.50, rapeseed 1.75 and
sunseed 1.50. The gross production tonnages provide the base
volume for each local grain economy, which subsequently
consumes, exports or stores any excess to those two basic needs. We
need to understand the local economy drivers and also the export
availabilities. These exportable volumes, and the extent to which
they are needed in other parts of the world, drive the price as we see
it on the futures markets and through the various cash or physical
prices the commercial world has access to.
AYP is the common industry abbreviation for area in terms of MHa,
yield in metric tonnes per hectare (Mt/HA) and production (the
product of A and Y). In this section, we will discuss the current AYP
for each major grain, where appropriate the whole grain economy for
the major grains, the evolution of the major producer economies since
the early 1990s and their changing role in price formation, as well as
some thoughts on how this may evolve. The following is a summary
of the total of 2,525 MMT of grain production:
850 MMT comes from the nine major maize producers (see Table
(member states of
ndependent States
c of South Africa
rs (see Table 7.3c) –
s (see Table 7.3b) –
or producers (see
, EU-27, Morocco,
and
167
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 168
COMMODITY INVESTING AND TRADING
❏ 460 MMT of rice comes from four major producers (see Table 7.7)
– Brazil, Thailand, China and India.
Of the soft oilseed total of 350 MMT:
❏ 250 MMTof soybeans are from four major producers (see Table
7.9a) – US, Argentina, Brazil and Paraguay;
❏ 60 MMT of rapeseed are from four major producers (see Table
7.9b) – Canada, EU-27, China and India; and
❏ 40 MMT of sunseed are from three major producers (see Table
7.9c) – Canada, EU-27 and CIS/FSU.
Hard oils (palm oil production) are dominated by Malaysia and
Indonesia at 38MMT (see Table 7.2).
Each major producer has a substantial grain economy for each
grain, and many interact since feedgrains are often combined with
oilseed meals – for example, to make complete animal diets. Each of
these economies is different and evolving. There are few clean lines,
with many feedgrains also being foodgrains, and feedgrains being a
major feedstock for biofuels (primarily ethanol, but also sugar cane),
as is vegetable oil (primarily biodiesel).
In Table 7.1 and subsequent tables we compare the last three-year
average of 2010, 2011 and 2012 (2010–12) to the previous three-year
averages of five years ago (2005–07), 10 years ago (2000–02), 15 years
ago (1995–97) and 20 years ago (1990–92), to avoid blips in individual
years. We see from this summary that, although the grains area
appears remarkably stable over time (3% 20-year growth), the
oilseeds area has expanded by more than 75%. For combined grains
and oilseeds, the 20-year yield growth has been 24% on an overall
hectare expansion of 13%, leading to a production increase of 40%.
For total arable land, the last five-year’s production growth came
evenly from area (5%) and yield (6%).
Additionally, we must remember that in this period the US took
around 160,000 km2 or 18.1 MHa (equal to 40 million acres, MAc) out
of production through its Conservation Reserve Program (CRP).
Also, in this period the EU ran its Cereal Set-aside programme. Setaside became compulsory in 1992, primarily as a means of reducing
the “grain mountain” as part of the Common Agricultural Policy. It
was originally set at 15%, before being reduced to 10% in 1996 and
then abandoned in September 2007.

FEEDGRAINS
There are three major feedgrains in the world – corn, sorghum and
barley – the production of which amounts to 1,045 MMT. However,
we must add significant volumes of feed wheat consumed in China
(10–12 MMT), the EU (49–57 MMT in 2007–12), Russia (13 MMT) and
170
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 171
GRAINS AND OILSEEDS
India (3–4 MMT), a total of 80 MMT. It is important to remember that
significant quantities of feed wheat produced globally is fed to
animals – the broad consensus says this is about 17% of global wheat
production, or 115 MMT.
The world harvests 855 MMT of maize annually, whose major
economies are the US (300), Argentina (25), Brazil (65), Mexico (20),
France (15), EU-27 (60), CIS/FSU (30), RSA (10), Thailand (5) and
China (195). Grain sorghum production of 60 MMT, widely distributed around the world, has major production in the US (7),
Argentina (5) and Australia (2). For both of these crops, there is also
significant non-grain production as feed, used as “silage” – best
described as a whole, above-ground crop, whose stems, leaves and
grain ear are pickled in vinegar (eg, formic acid) to preserve it, before
it is stored and fed to livestock over the following winter. Barley
totals 130 MMT, of which Canada (10), EU-27 (55) and CIS/FSU (25)
are the major economies. Note that, at 130 MMT, barley production is
greater than China’s wheat production (second only to EU wheat
production) and twice that of Brazil’s corn production (the world’s
third-largest corn producer). Both barley and sorghum are in decline
in terms of devoted area and the world barley and feed-wheat
markets are the same size.
The major feedgrains are starch or carbohydrate producing and
consumed by animals, hence the feed designation. They also have
considerable industrial use. We can divide the animal kingdom into
two stomach types: monogastric and ruminant. We humans are
monogastric, having “one simple stomach”, as are pigs and
chickens, while cattle are ruminants, having a “rumen”. The rumen
can be thought of as a vat, capable of stewing and digesting highly
fibrous food, such as grass and leaves, which contain carbohydrates
bound by lignin, a complex fibre. Feeds such as potatoes require
boiling to break down their complex carbohydrate structure to
make them easily digestible for monogastrics. Grains are simply
processed by grinding to break down the husk or outer covering,
rendering them easily digestible to a ruminant, while full milling
and husk removal makes them also easily digestible by monogastrics. As the reader will be well aware, there is an ongoing
conflict between ease of digestibility and the many essential nutrients found in the husk – wholegrain bread being the classic
compromise for humans.

GRAINS AND OILSEEDS
For many animals, grains are a simple supplement for their diet
(eg, beef cattle that consume mainly forage), while dairy cows, pigs
and poultry require a considerable amount of protein to be added to
their diet since they perform optimally with a 20–25% protein feed,
almost twice that of any cereal grain. This implies a 75:25 grain:meal
combination. Therefore, major feedgrain consumers must also
produce or import their protein needs, making the EU a major
importer of softseed proteins. Although it may seem very straightforward, the Pearson Square formulation works surprisingly well for
estimating diets for forecasting animal or aquaculture needs, and is
easily found with a web-search.
Biosystems, of which one is the stomach, are complex and a series
of associative effects can be observed. We do not digest equally meat
and potatoes that are eaten separately, as compared to eating combinations in various proportions. The cooking method and previous
meal also influence digestion. We do not similarly digest meat and
rice in the same way as meat and potatoes. This leads to feed conversion efficiency (FCE), a metric which is the first step towards
metabolisability, the rate at which we actually use the nutrients we
have ingested. FCE is normally expressed as kilograms (kg) of dry
matter output per Kg of DM feed.
In principle, as we allocate raw materials, feedgrains should only
go to those processes that efficiently transform them into human
food. For example, this means that we would not feed grains to cattle
other than what is required to optimise their ability to digest cellulosic feeds. If this were the case, and we were simply economic
actors, we would have more than enough to feed the world –
however, this would have the effect of large parts of the common diet
disappearing around the world. We prefer to eat as we please,
dependent on prevailing price and income.
Associative effects include the reality of optimised nutrition,
combining carbs, proteins and fats to get the optimal feed conversion. Diets have been balanced at the commercial level based on the
least-cost formulation since the 1960s, and it remains a simple linear
programming exercise. Animal nutrition has advanced much faster
than human nutrition, not least because we can isolate genetics and
enforce diets for animals, before butchering them to measure the
output much more easily than with humans. Optimising nutrition is
scientifically easy but socially complex, and we can imagine very

different optimal strategies for an Olympic athlete and a couch
potato, or a new born infant and an octogenarian. Calories are to
modern nutrition what gasoline was to the Model T Ford: raw
energy. We have come to think in terms of metabolisability (usefulness) of carbs, proteins and fat, and also the various micronutrients
and salt balances that influence our bodies and lives.
Wheat and barley belong to a category of grains (which includes
oats) that the US Department of Agriculture (USDA) refers to as the
“small grains”, and which are reported separately. A report issued
annually in December and various updates provide detail on a stateby-state basis of the AYP of these three crops. The EU treats wheat in
the same way that the US does maize, since it is the base of animal
feed, and consequently describe everything else as “coarse grains”.
The reader must be careful to compare coarse grains in different
grain economies – they mean different things.
There are over a dozen major feedgrain economies in the world,
all growing grains and other food and feed in rotations – customised
for the location, growing degree days (GDDs) and current
economics. A major grain economy is defined by the author as one
producing more than several million tonnes in excess of its local
requirements through rotation. An example is Ukraine, which
produces roughly 0.5 tonnes of wheat per capita. Its enormous
simultaneous local production of potatoes leaves it with a huge
exportable surplus of basic carbohydrate. The US produces one
tonne of corn for every inhabitant. Once you get in the grain or
oilseed producing business as a farmer, the quality of your output
and its ultimate designation as food or feed will depend on the
variety you chose to plant, how you cared for it, mother nature
(weather), evolving global demand, the market where you choose to
sell it and the degree to which it is carefully handled, processed,
marketed and blended.
In the early 1990s, the US dominated the maize market globally as
a producer and exporter. Its exports were residual to its own animal
feed and food, seed and industrial (FSI) needs, and it carried large
stocks. In 1990/91, the US had almost 35 MMT in stock, producing
200 MMT and exporting 55 MMT. The US Maize crop year (CY)
begins in September and ends before or at the start of harvest in
August of the subsequent year. Optimal planting is between April
1st and May 30th while harvest runs from August 20th to November

30th. Both run progressively northwards. The current crop was
planted two weeks late. The US plants 353.5 MHa, and has a threeyear average yield of 8.875 MT/Ha, which includes the disastrous
harvest after the drought of 2012. Yields are normally expected to be
over 9.0.
Since the two major drivers of domestic maize consumption for all
major producers are Feed and FSI, Table 7.4 takes the unusual
approach of stripping out the “corn-for-ethanol” maize demand to
allow accurate comparison with other countries. We can then
proceed to examine the US and other maize-economies sequentially
and draw some conclusions for the future. Table 7.4 follows usual
USDA protocol so Area and Yield are directly comparable with
USDA. Thereafter, line by line, it strips out the ethanol demand
which is not a grain demand and allows us to get to non-fuel FSI by
freezing fuel ethanol demand at 1990/91 CY-levels and shows in the
Adjusted domestic use row that demand is in fact almost flat in the
US from 1990 CY to 2013.
The feed economy
One way to quantify grain demand is to employ feed-use data and
grain-consuming animal units (GCAUs), factors that allow comparisons of grain demand among different types of livestock. One
GCAU is 2.15 tons (short tons have 2,000 pounds, while metric have
2,204.6). The USDA has developed a different factor for each type of
livestock based on the average amount that one such animal
consumes in a year. For example, a dairy cow has a GCAU factor of
1.0474, while a broiler has a factor of 0.002. Using these factors, we
can see that one dairy cow will use the same amount of grain (1.0474
× 2.15 tons = 2.25 tons) in a year, as approximately 523 broilers (one
broiler will consume 0.002 × 2.15 tons = 0.0043 tons, and 2.25 divided
by 0.0043 equals 523 broilers). The major GCAU factors are feeder
cattle: 0.0547, broilers: 0.002, layers: 0.0217, turkeys: 0.0155, dairy
(cow + calf): 1.0474 and hogs: 0.2285. Informa Economics, Inc. offers
the best analysis of GCAU’s and also protein-consuming animal
units (PCAUs), allowing us to view the relative intensity by animal
type of each major feed component side by side.
Globally, we are eating an increasing amount of white meat,
resulting in greater numbers of monogastrics and increased feed
conversion efficiency (FCE). Two important issues arise here: there
176
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 177
GRAINS AND OILSEEDS
has been a dramatic increase in industrial (large-scale) animal
farming since the early 1990s, as well as further urbanisation, which
are additive in effect. The effort to supply large quantities of meat
requires significant supply chains and consumer packaged goods
(CPGs) provided by companies such as Nestlé and Danone, meat
companies and retail supermarkets.
Animal feed demand is not hardwired in the same way as FSI for
two reasons. The feed compounder can choose many feeds to make
the ration, and the consumer has a lot more discretion, cut by cut, as
to what meat they choose to eat. It is beyond the scope of this chapter
to discuss global meat demand, but we do size the larger food
protein economies – US, China, EU, Russia, Brazil and India (Table
7.5) – and look at the broad consumption figures. In addition, we
note that, in much of the world, consumers will switch between
different food proteins as their relative price changes. Price changes
for proteins are frequently more volatile than for grains or oilseeds.
Pork accounts for 60% of China’s meat protein consumption. In
general, poultry is substituted as a meat protein when pork prices
reach high levels. Conversely, when pork prices are affordable,
China’s consumers prefer to purchase pork products.
Before looking at animal feed, we should briefly review animal
protein consumption. For some inexplicable reason, it is unusual to
find this critical information in most discussions on grains and
oilseeds. Table 7.5 shows that China leads on production and
consumption, consuming twice as much meat as the US, while in 1990
they consumed roughly the same. In terms of quick numbers, this
means the average Chinese person eats half as much meat protein as
the average American, 40% more pork per capita, one quarter as much
chicken and one ninth as much beef. From a tiny chicken industry in
the early 1990s, China has come to consume more chicken than the US,
at some 14 MMT. Not only does China consume 33% of the world’s
meat, but also 33% of the world’s fish and aquaculture, and in 2010 it
became the largest animal feedgrain user, including an estimated 12
MMT of wheat. In terms of total animal protein, China is twice as big a
consumer than both the EU 27 and US.
Outside of China, Brazil has become a major meat exporter. In
addition, despite being widely thought of as a vegetarian country,
India consumes almost 20 MMT of meat per annum. It is estimated to
consume 5.5–6.0 kgs per capita of chicken with a retail value of
177

US$9.0 billion, and it is widely touted to become more populous than
China’s 1.35 billion people. Therefore, the forecasted 20% growth in
chicken consumption in India will have an impact on the grain
markets. Russia is seriously underserved in the animal protein category. In the not too distant future, the author would expect the
Chinese and Brazilian poultry economies to surge past the US and
EU markets. As a final caution against analysing enormous populations, remember the ag majors dig a lot deeper into this kind of data,
and categorising 100 million people – never mind 1.35 billion – as
behaving in a homogenous way is intuitively risky.
The (FSI) industrial corn economy
To compare FSI of the major producers we must use the adjusted
true corn supply and demand (S&D) for the US. It has a 45 MMT FSI
demand, roughly half the size of its feed consumption, growing 25%
in 20 years and from 15% to 26% of the adjusted production which
makes it globally comparable. Argentina consumes 2.2 MMT (up
90% in 20 years, yet declining from 14 to 8% of the crop); Brazil
consumes 7.0 MMT (up 100% and down from 14% to 11% of the
crop); Ukraine uses 1.5 MMT (up 33%, from 21 to 7%); Russia 1 MMT
(down 40%, from 44 to 10%); the EU 15.5 MMT (up 45%, from 30 to
28%); RSA 4.5 MMT (up 15%, from 46 to 35%); China 64 MMT (up
100%, from 27 to 31%) and India 8.3 MMT (up 23%, from 78 to 42%).
Non US major producers total 110 MMT in FSI, an important 2.4
times the US, growing 84% over 20 years and declining only slightly
from 28 to 25% of local production. The industrial corn economy is
aimed at high value-added processing, and a typical analysis is
heavily clouded by the conventional reporting process of FSI, which
includes fuel ethanol. FSI has no meaningful seasonality while feed
demand does.
There are two main types of corn processing: dry milling (EtOH)
and wet milling (sweeteners). The products of each type are utilised
in different ways. Over 80% of US ethanol is produced from corn by
the dry milling process. The ethanol is dehydrated to about 200º
proof using a molecular sieve system, and a denaturant such as gasoline may be added to render the product undrinkable. With this last
addition, the process is complete and the product is ready to ship to
gasoline retailers or terminals. The remaining stillage then undergoes a different process to produce a highly nutritious livestock feed

GRAINS AND OILSEEDS
(DDGS). The carbon dioxide released from the process is also utilised
to carbonate beverages and in the manufacturing of dry ice. Ethanol
yield is constantly rising and water use efficiency improving. The
initial assumption that biofuels were good for the environment
because they had a smaller carbon footprint is debatable regarding
the contention that the production of grain alcohol, and therefore
E15, may actually have a greater environmental impact than fossil
fuels.
US non-fuel FSI averaged 15% of production across the 20-year
period, amounting to some 42 MMT. In theory, this all comes from
wet milling, a process which takes the corn grain and steeps it in a
dilute combination of sulphuric acid and water for 24–48 hours in
order to separate the grain into many components. The slurry mix
then goes through a series of grinders to separate out the corn germ.
This process is the backbone of industrial processing for the production of fructose, glucose, dextrose, starch, potable alcohol and
industrial alcohols. These figures are typical of an industrial maize
economy found all over the world – with the exception of highfructose corn syrup (HFCS) and fuel ethanol, which are US-specific.
In 20 years, US production of HFCS increased by 33%, glucose and
dextrose by 54%, starch by 14%, potable alcohol was unchanged and
cereal consumption increased by 64%, largely driven by the USDA
food pyramid. The growth is predictable since the plants are
announced and take time to build. This industrial demand is largely
non-switchable. For example, it was affected by a 2006 agreement
(which became effective in 2008) to allow sweeteners to flow from
the US to Mexico without tariffs.
HFCS is produced by wet milling corn to produce corn starch,
then processing that starch to yield corn syrup, which is almost
entirely glucose, and then adding enzymes that change some of the
glucose into fructose. The resulting syrup (after enzyme conversion)
contains naturally 42% fructose, and is consequently called HFCS 42.
Some of the 42% fructose is then purified to 90% fructose (HFCS 90).
To make HFCS 55, the HFCS 90 is mixed with HFCS 42, and this
increased fructose percentage gives it the same “sweetness” taste as
sugar (which is why it is called “high” fructose corn syrup).
A system of sugar tariffs and sugar quotas imposed in 1977 in the
US significantly increased the cost of imported sugar, and US manufacturers therefore sought cheaper sources. HFCS, as it is derived

from corn, is more economical because the domestic US prices of
sugar was twice the global price while the price of corn was kept low
through government subsidies to growers. HFCS became an attractive substitute, and was preferred over cane sugar by the vast
majority of US food and beverage manufacturers. Soft drink makers
such as Coca-Cola and Pepsi use sugar in other countries, but
switched to HFCS in the US during the mid-1980s. In 2010, the Corn
Refiners Association applied to allow HFCS to be renamed “corn
sugar”, but this was rejected by the US Food and Drug
Administration in 2012.
Barley (Hordeum vulgare L.) is a member of the grass family and
therefore closely related to wheat, and is a major cereal grain.
Important uses for barley are as animal feed, as a source of
fermentable material for beer and certain distilled beverages, and as
a component of various healthfoods. It is used in soups and stews,
and in barley bread. Malting barleys are normally separate and
distinct varieties from feed barley. In a ranking of cereal crops in the
world, barley is fourth, both in terms of quantity produced and area
of cultivation. For our purposes we include it in feedgrains although,
as with most of these crops, the lines are blurred.
Canada, the EU and CIS/FSU are the major barley producers (see
Table 7.3b), accounting for 70% of global production, and their yields
are quite different at 3.125, 4.25 and 2.00 MT/Ha, respectively, giving
very different competing crop economics. As one can imagine, the
decline in area has been greatest in the low yielding producers, and
in 20 years Russia fell from almost 50 MMT to almost 25, and global
production decreased from 170 to 130 MMT, down some 33%, of
which the big three declined by 40, 15 and 50%. Barley has been
closely associated with small farms and on-farm feeding, which
means the decline will continue.
Sorghum is in a genus of numerous species of grasses and a relative of other C4 plants like maize and sugarcane. With lower yields
than maize the US (the world's largest producer, see Table 7.3c) has
more than halved its sorghum crop to 10% of global production, the
remainder being scattered around the world where it may be locally
important as food or feed. Many species are cultivated in warmer
tropical climates worldwide. It is also biologically in the same tribe
and subfamily as sugarcane and might have been grown widely in
Brazil where local tastes prefer rice as food carbohydrate. Globally its

stagnant 60 MMT production is neither important in world trade nor
expected to be so.
FOODGRAINS
There are two major foodgrains: wheat and rice. The world harvests
670 MMT of wheat annually (see Table 7.6), of which the major
wheat economies are the US (60), Canada (25), Argentina (15), Brazil
(5), EU-27 (135), Morocco (5), CIS/FSU (90), Turkey (15), China (120),
India (85) and Australia (25). World rice harvests is 460 MMT (see
Table 7.7), of which Brazil (10), Thailand (20), China (140) and India
(100) are the largest economies. There are thousands of wheat varieties being grown in the world, each selected, bred and adapted
based on locality and consumer preference.
Table 7.6 shows that US wheat production is flat (area declines
and yield improves) and expected to decline as maize takes up more
land for ethanol. Canada, Argentina, Australia and Brazil are stagnant, while the EU, China and India have grown quite dramatically.
In addition, the FSU declined dramatically as it became more
market-based, but has considerable potential to recover production
through the use of modern farming methods. Yield growth around
the world remains good, in many cases due to suboptimal wheat
areas being taken out of production in China and the FSU.
Throughout the world, there are various ways of categorising
wheat, largely dependent on intended use. We can think of wheat
globally and genetically as having 10% protein content, often
referred to as its fair merchantable quality (FMQ). FMQ changes
with variety, husbandry and weather. While the EU tends to specify
wheat by specific weight (in the US, it is thousand grain weight,
TGW) measured in kilograms per hectolitre (Kg/hl) and variety,
feed wheat is generally assumed to have a 72 kg/hl FMQ (UK Liffe
contract spec) and milling or baking wheat to have a 76 kg/hl FMQ
(French Euronext contract spec).
The most common simple laboratory test for protein quality
(gluten) is the Hagberg falling number (HFN), which measures the
rate of fall of a plunger through a column of water/flour mix, representing its stickiness or so-called “gluten extensibility” – the ability of
the wheat to form a uniform rising dough. From the most simple
feed/food designation in Europe, each major wheat exporter has its
own preferred designations. A wheat chapter that does not discuss
183
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 184
COMMODITY INVESTING AND TRADING
type by geography and consumption would be pointless, so we will
take a deeper look at China and India. Wheat varieties can vary over
100 miles, and there are thousands around the world.
In fact, there are several hundred varieties of wheat grown just in
the US, all of which fall into one of six recognised classes. Wheat
classes are determined not only by the time of year they are planted
and harvested, but also by their hardness, colour and the shape of
their kernels. Each class of wheat has its own family characteristics,
as related to milling and baking or other food/feed use. Wheat
production by type across the states and then subsequently for
spring, winter and durum, and the intensity by county within each
state can be seen at: http://www.thefreshloaf.com/node/4632/major-wheat-growing-regions-us-reference-maps.
The largest volume of US wheat is of Chicago Board of Trade
(CBOT) type and specification and is often referred to as simply W.
CBOT-type wheat is both an animal feed and capable of making
biscuit dough, or a simple unleavened dough, and has low protein
content and poor “gluten extensibility”. Kansas City Board of Trade
(KCBT) wheat (often referred to as KW) is true bread wheat destined
for human consumption but capable of being fed in small quantities
with other grains to animals. Its gluten extensibility is sufficient to
capture a bubble of air and allow the dough to rise to produce a loaf
of bread. Minneapolis Grain Exchange (MGE) wheat (often referred
to as MW) is best thought of as a high-class or technical wheat
capable of making fine pastries such as croissants. The gluten is
extremely flexible and can produce a low-dough large bubble.
W has no protein minimum per se, while KW has 11% and MW has
13.5%. All three futures contracts are based on #2 grade, which is a
minimum TGW, #1 would be higher and sub-economic to deliver as
we can simply blend it down. All of these markets carry a variety of
scales that adjust for delivering #3 grain (lower specific weight), and
KW and MW allow for penalties to be deducted for protein levels
down to 10.5% and 13.0%, respectively. “Protein scales” refer to the
per 0.5% or 1.0% value for protein quoted in the physical or cash
markets, and represent the value of different grades that are blended
by millers and shippers to make actual grists (the baker’s wheat
“slate”) or shipping contract minimums. Protein levels do not blend
linearly but are close enough for anything we need to discuss here.
Baking is in fact a science, and there is a large body of work available
184
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 185
GRAINS AND OILSEEDS
on wheat qualities, baking and the use of gluten-extenders, for
example, a man-made additive intended originally for use in poor
harvests but now used widely to create uniformity.
Although many talk about declining wheat per capita consumption
and the rise of corn and soybean production, this masks a much more
complex picture. To talk of wheat and bread is a serious mistake,
demographically. The grains and oilseeds industries of other countries are substantially different to the OECD; Mexico thinks about
tortillas more than loaves of white bread, the Indian/Pakistan wheat
economy is very large but flour production and sales direct to the
consumer, rather than bread, remains a substantial industry, while
Asian noodles are a major source of wheat consumption all over the
globe, not just in Asia. Although much has been written on wheat and
foodgrains, most focus on the easily researched OECD producers: US,
Canada (three planting zones, 14 classes and three or four grades for
export of each variety), Australia (five planting zones, six principal
grades targeting 13 end uses, from Indian bread to Udon noodles and
Asian instant noodles), Argentina (seven planting zones, three major
categories, four flour grades) and France (17 planting zones or areas,
four classes and four grades, all variety-specific). We will look at the
two most populous countries, China and India, to provide a cross
reference of their enormous wheat economies rarely found outside an
ag major or the most serious investor. Without understanding these
two rapidly evolving wheat economies there should be little expectation of understanding price evolution.
Prior to the expansion of the EU to 27 countries, China was the
world’s largest producer and consumer of wheat. Comparative
advantage has led China to discourage low-quality wheat production, and it has reduced the amount of land devoted to wheat since
the early 2000s. It imports as a way of balancing quality not quantity,
and the US wheat class designations will not advance your understanding of Chinese wheat needs. Its planting zones can be divided
broadly into three: hard wheats around the Greater Khingan
Mountain range, hard wheats along the Yellow, Huai and Hai rivers
and, finally, soft wheats along the lower Yangtze river. They include
nine classes (the first is H or S for hard and soft, then W or R for white
or red and W or S for winter or spring – the main ones are HWW,
HWS, SWW, SWS, HRW, HRS, SRW, SRS and other), and five grades
(79+, 77+, 75+, 73+ and 71+ Kg/Hl) by specific weight and a variety
185
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 186
COMMODITY INVESTING AND TRADING
of other quality characteristics, including moisture and foreign
matter.
The nine Chinese grades are further divided into two classes of
high-quality strong gluten wheat, two classes of high-quality weak
gluten wheat and three other qualities for specific end-uses. Each
grade class has a specific flour quality, including HFN and a range of
other specific qualities. In addition, each of the classes and flour
grades are identified by planting zone. Some 10% of the wheat is
used for high-quality bread cookies and dumplings, some 50% for
steamed bread, noodles and instant noodles, and the remaining 40%
is used locally for home baking or small bakeries. Urbanisation and
the industrialisation of its food industry is dramatically changing the
patterns of consumption in China. Despite their large total animal
protein consumption, the population effect means China (and
indeed Asia) depends heavily on foodgrains for nutrition.
Noodles represent some 40% of total flour consumption, and are a
major staple in East and Southeast Asian countries. Apart from
wheat flour, they can be made from rice flour, potato flour, buckwheat flour, corn flour, bean, yam and soybean flour. While pasta is
made from tetrapolid durum wheat (Triticum durum), noodles are
made from the hexaploid Triticum aestivum, which contains gluten,
which reacts to the pressure during the sheeting process. Eggs are
frequently added to provide a firmer texture.
Given that wheat consumption in the form of Asian noodles
exceeds the total US wheat production, we can understand its significance in the forecasting of demand for wheat round the world.
Chinese noodles are typically made from hard wheat flours,
Japanese noodles from soft wheat of medium protein. By colour,
they are typically classified as white (containing salt) or yellow
(containing alkaline salt). White salt noodles include Japanese
noodles, Chinese raw and dry noodles. Yellow noodles include
Chinese wet noodles, Hokkien noodles, Cantonese noodles, Chukkamen, Thai bamee and instant noodles. Over 50 billion meals are
annually served around the world that contain ramen noodles alone.
Asia imports US HRS, DNS, HRW, SRW and SWW, Australian standard white (SW), premium white (PW) and prime hard wheats (PH),
as well as Canadian Western Red Spring (so called CWRS), Canadian
Western Red Winter, Canadian Prairie Spring White and Canadian
Prairie Spring Red wheats to blend with local wheats to make
186

GRAINS AND OILSEEDS
noodles. China consumes 35% of global instant noodles, just twice as
much as Indonesia, which is twice that of Japan. The US and South
Korea consume one fifth as much as China.
Steamed bread accounts for 60% of flour consumption in
Northern China (where it is a staple) and 20–30% in the South (where
it is a dessert). In Asia, it represents 5–15% of flour consumption
depending on the country, and it is popular in the Philippines, for
example. It is made predominantly from soft-to-medium hard
wheats and, while it is prepared somewhat like a western pan bread,
it is then steamed rather than baked. There are three principal types
with varying protein and gluten qualities – Northern, Southern and
Taiwanese. The Northern type is typically made from local wheat,
and has 10–11% protein. The Southern type has added sugar and
baking powder. The Taiwanese type has the highest protein, while
all three types contain yeast. The steaming process produces a
higher-quality food than baking as it destroys less of the amino acids
(especially lysine) than the higher temperature baking. However, it
is less conducive to large-scale production since much of its eating
qualities are associated with being freshly steamed. It loses quality
when re-steamed and its shelf life is short compared to baked bread
due to the higher moisture content. This will inevitably lead to what
the US and Europe call “in-store baking” as a means of bringing
large-scale industrialisation to the cities.
India’s second largest foodgrain crop is wheat, but strategically it
has tremendous and growing importance with an ever-larger population, as it is a non-monsoon-based crop. It has six major growing
areas: the Northern Hill Zone (NHZ, 1.2 MHa), the North West Plain
Zone (NWPZ, 9.0 MHa), the North East Plain Zone (NEPZ, 9.0
MHa), Central Zone (CZ, 5.0 MHa), Peninsular Zone (PZ, 1.0 MHa)
and the Southern Hill Zone (SHZ, 0.2 MHa). Some 90% of Indian
wheat receives irrigation, although in the NHZ this does not occur at
higher elevations but closer to rivers unless the crops are close to a
river.
The NWPZ is a large fertile part of the Gangetic Plain and is more
than 90% irrigated, with crops maturing in 140 days and multiple
days with lows of less than 5° C. Wheat plants tiller well and develop
many spikes, so yields are high. However, disease can be a problem
due to mono-cropping (poor rotation). Temperature spikes at grain
fill can hurt yields in the same way as in the US Midwest. The NEPZ

is humid with a large number of minor rivers for irrigation, and it
also suffers from wheat diseases associated with a humid environment. Wheat matures here in 125 days and is susceptible to
unneeded rain showers at harvest time. The CZ and PZ are highland
deep soil areas but difficult to irrigate and may receive only two
applications of water per season, and with high temperatures we see
short growing seasons and poor yields.
India has developed and distributed 200 of its own varieties of
wheat since the 1980s which see several days with temperature lows
of less than 5°C predominantly targeted for the higher yielding
regions. Disease control is effected by using the SHZ for plant
breeding. The many problems associated with Indian wheat production have been solved around the world and will be in India as well,
although this will take time. These problems include but are not
limited to poor acceptance of new varieties and the widespread
planting of retained production from year to year, poor mechanisation, lack of modern harvesting methods and inexperienced machine
operators, which results in low-quality grain samples and lots of
admixture of foreign matter.
A considerable amount of Indian wheat is consumed as chapati, a
flat unleavened bread. The warm wheat areas have higher protein
than the cool NHZ. Hill wheats are widely used for biscuits/cookies.
PZ wheat is used for crackers and cookies due to its protein level and
quality. The baking industry is largely based in the south, which has
a deficit in wheat and the vast size of the country makes transport
expensive. Significant quantities are exported for hard currency, but
the industrialisation of baking and the introduction of whole grain
branded flour will lead to improvements in revenues. Better prices
for wheat will improve flour yields, and urbanisation will change
farming practises and consumption patterns, making India a significant importer and producer of higher-quality breads for its
increasing population.
India will become an importer of higher-quality wheats over time,
which will have a significant impact on world wheat flows. With
only five classes (medium hard bread wheat, premium hard bread
wheat, biscuit wheat, durum and Khapli wheat, a particular Indian
wheat used for semolina) and no effective grading due to a largely
flat price structure for wheat within classes under the Indian state
run Public Supply Distribution (PSD) system, the Indian wheat

market will evolve as it becomes more market driven. Most ethnic
breads (chapati, naan, tandori, rumati, roli, puri and bhatore) are
made from medium-hard bread wheat. The Indian government has
traditionally supported domestic wheat prices at a significant
premium to world prices and they have carried significant stocks to
allow it to intervene in the domestic food price.
Given the overall excitement in the wheat market of 2007, we will
review the run-up to this bull market, its causes and its effects. As
with all great bull markets, its roots lay in the previous year’s crop,
with widespread problems for the major exporters (US, EU-27,
Canada, Australia, Argentina and Russia). Since the early 2000s,
these countries have produced between 271 (2006–07) and 344 MMT
(2008–09), carried stocks as low as 36 MMT (end-2007) and as high as
73 MMT. Exports have ranged between 88 and almost 125 MMT and
stocks have responded dramatically, to build or draw-down, as price
signals have changed. At the beginning of 2006–07, their stocks stood
at 65 MMT and by the beginning of 2008–09 had fallen to 36 MMT, a
10-year low.
Of these countries, all but Russia has highly visible stocks. Russia
typically has a stock/use ratio of 10%. The EU has highly volatile
wheat production, producing 133 MMT in CY2002/03 and
111/147/132 MMT in the subsequent years, respectively. In CY2005–
06, its crop decline year-on-year (yoy) of 14.5 MMT was absorbed by
the other major producers. The following year, however, saw disappointing crops with the US down 8.0 MMT, the EU down 7.5 and
Australia down a disastrous 14.5 MMT. This 30.0 MMT dip was not
offset by the other major exporters and exports from the group
dropped to 88 MMT. Australia has a volatile, rain-dependent wheat
crop and, while production ranges between 10.0 and 30.0 MMT, it is
in fact rather binary, producing less than 15.0 MMT in dry years and
more than 25.0 MMT in wet years.
In 2006–07, the world became increasingly concerned with wheat
and the US drew stocks from 15 to 12 MMT, cutting domestic use and
exports. Similarly, the EU drew stocks by almost 10 MMT and also cut
domestic use and exports. Canada boosted exports and drew stocks,
and Australia halved its stocks to export more than 16 MMT versus
the previous year’s 23 MMT. Russia maintained big exports at 10
MMT, and Argentina almost emptied its stocks completely. At times
like these, we turn to the minor exporters (Ukraine, Kazakhstan, India,
189
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 190
COMMODITY INVESTING AND TRADING
China and Turkey) to see what they can contribute. The Ukraine crop
dipped from 18.0 to 14.0 MMT, and they drew stocks to maintain
exports at 3.5 MMT, down 3.0 on the previous year. Russia agitated for
a Ukraine export ban. Kazakhstan exports surged from 4.0 to 8.0 MMT
on a decent crop and a stock draw. India, however, who can be a 5.0
MMT exporter, was coming off two disappointing crops and had low
stocks. So, not only were they absent from the export market in
CY2006/07, but in fact imported almost 7.0 MMT. China’s production
rose 11.0 MMT yoy, but they were already in stock-building mode and
withdrawing from the export market strategically. China therefore
barely exported 1.0 MMT more than the previous year. Turkey was
down to bare minimum stocks and had a sufficiently reduced crop in
CY2006/07 to be absent from the export market. In fact, across the
minor exporters there was a significant increase in imports yoy,
primarily lead by India and indicating the structural shift in the two
most populous countries in the world; China is now a structural
importer, and while India may come and go as both exporter and
importer, it will inevitably follow China to the structural importer
category.
Among the major importers, Egypt built stocks by 1 MMT in
2006/07 and increased imports yoy, Brazil increased imports by 1
MMT, Japan maintained imports, Indonesia raised imports and
Algeria cut theirs by an offsetting amount. South Korea, Nigeria,
the Philippines and Morocco cut imports modestly, while Iraq
imports took a big downturn and Mexico was unchanged. Overall,
major importer demand dipped by only 2.0 MMT in the face of a
30.0 MMT dip in major exporter production, pinpointing the very
staple nature of wheat demand and its insensitivity to price. It
should be clear to the reader that every large market player has
access to the shipping fixtures, or grain movements, by loadport
and discharge port.
We then entered the major bull run. Any problems in the 2007
growing season would cause a major disruption, and the hedging
pressure and speculative pressure increased to intense levels. US
production rebounded by 6.5 MMT in CY2007/08 and another 12.0
MMT in CY2008/09, but only after drawing stocks to a low 8.0 MMT.
Disastrously, the EU had more problems in 2007/08 and production
dipped another 5.0 MMT, and stocks hit a near record low. By
CY2008/09, a world-saving rebound of 31 MMT would be

harvested, but not until the market had gyrated wildly. Adding to
the woes in 2007, Canadian wheat production dipped 5.0 MMT, and
they too drew stocks heavily to record a low of barely 4.0 MMT.
Australian production recovered, by a mere 2.8 MMT, to a sub-14.0
MMT crop. Argentinian and Russian crop production increased
slightly, and the major exporters saw their total production increase
by 6 MMT and stocks draw another 7.0 MMT on top of the previous
year’s 20.0 MMT decline. Collectively, their production would surge
by more than 66.0 MMT in CY2008–09 to end the bull market. Minor
exporters had a domestic production rebound of 8.0 MMT but
reduced their exports yoy, and while they cut their imports in half
they were also building stocks. Although there was some variance
between major importers, stock were built modestly and imports
rose modestly.
Wheat exhibited the classic volatility of a market with inelastic
demand and whose price-solving mechanism is to scale a steep
marginal supply curve to increase production at the expense of
competing crops. This occurred at the same time as crude oil price
was increasing dramatically and maize demand for ethanol surged
in the US. As in Table 7.6, the wheat supply from 2005–07 to 2010–12
would only increase in area by 2%, yield would rise 7% and production by 10%. Production increases were 20% in the EU, 18% in China,
14% in CIS/FSU, 13% in India and 9% in the US.
As a foodgrain, rice provides the most widely consumed staple
food of over half the world’s population (see Table 7.7), especially in
Asia and the West Indies. It is the seed of the monocot plants Oryza
sativa (Asian rice) or Oryza glaberrima (African rice). It is the predominant dietary energy source for 17 countries in Asia and the Pacific,
nine countries in North and South America and eight countries in
Africa.
Rice provides 20% of the world’s dietary energy supply, while
wheat supplies 19% and maize 5%. It is the grain with the secondhighest worldwide production after maize, but since a large portion
of maize crops are grown for purposes other than human consumption, rice is the most important grain for human nutrition and caloric
intake, providing more than one fifth of the calories consumed
worldwide by the human species. There are many varieties of rice
and culinary preferences vary regionally. In the Far East, there is a
preference for softer and stickier varieties.

GRAINS AND OILSEEDS
Rice yields continue to grow while area is largely stagnating,
China’s dramatically better yields than India means it produces 40%
more rice from two-thirds as much land. India’s yield growth at 33%
in 20 years is, however, twice that of China, and Brazil’s yield has
doubled in the same period. As previously mentioned, the Indian
crop is monsoon-driven. World trade is small and most countries
that consume rice grow their own.
To close the foodgrain section, some basic numbers are provided
for processed food sales. Worldwide, they are approximately
US$3.5 trillion, and the industry is growing. The processors are giant
companies that own huge brands, the CPGs such as Nestlé SA. These
companies dwarf the ag majors who are their suppliers. The food
industry is a complex, global collective of diverse businesses that
supply much of the food energy consumed by the world’s population. Only subsistence farmers, those who survive on what they
grow themselves, can be considered outside of the scope of the
modern food industry.
In developing country markets, the two reference points are the
US and the UK. With populations of 313 million and 55 million,
respectively, they can be used to estimate what the food economies
of less-developed countries will likely look (more) like in the next
few years.

OILSEEDS – VEGETABLE PROTEINS
We harvest 355 MMT of the three major softseeds (soybeans, rapeseed and sunseed, (see Tables 7.8 a, b and c)), of which 260 are
soybeans, 60 are rapeseed and 35 are sunseed. The major soybean
economies are the US (85), Argentina (50), Brazil (75) and Paraguay
(5). For rapeseed the big four economies are Canada (15), EU-27 (20),
China (15) and India (5). For sunseed the big three economies are
Canada (5), EU-27 (5) and CIS/FSU (20). The softseeds yield
vegetable oil and high-protein meal in ratios of 19/35/33% of oil and
79/63/65% meal from soy/sun/rape crushing, the balance being the
hulls or shells. This means a global soft oil output of roughly 50, 12
and 20 MMT, respectively. Much of the softseeds are crushed and
their products consumed locally. Historically, we have described
China, or Asia, as “oil deficit” and the EU as “meal or protein
deficit”. Global exports of the three softseed oils are estimated by
Agrimax at 8.0, 5.0 and 3.0 MMT respectively, compared to global
palm oil flows of more than 38.0 MMT.
In the early 1990s, the US dominated global soybean production.
By a decade later, Brazil and Argentina combined produced as much
as the US, and by the early 2010s Brazil alone threatened to match the
US in production. World planted area has grown by almost 90%.
World yields have grown by 25%, and production has surged by
135%. Brazil has the highest yields, followed by the US and
Argentina, but it is important to note that yield advancements are in
decline and largely occurred during the 1990s.
In contrast, hard oils (their physical state at room temperature) are
produced primarily from fruit (as compared biologically to seeds).
The most commercial is palm oil, but the family also includes
coconut oil and others. Butter and lard (animal fat) are also included
in this category. Malaysia and Indonesia dominate palm oil production and annually export some 19.0 MMT each, amounting to more
than 65% of global vegoil (the common industry abbreviation for
vegetable oils) trade flows. Since they come from fruit, there is an
associated pulp that remains from processing, normally returned to
the soil as fertiliser.
The four countries that dominate world rapeseed production,
with 90% of production, are all major wheat producers, and rapeseed
grows very nicely in a rotation with wheat. EU yields are more than
170% of the world average and planted area is now more or less
196
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 197
GRAINS AND OILSEEDS
equal to each of the other producing countries, at 7 MHa each. EU
area planted has driven the global yield growth, expansion being
primarily for biodiesel production. Indian yields are abysmal, but
domestic consumption is protected by the large costs of importing
rapeseed from major producers and trucking to the interior. China
dominates global rapeseed trade.
Sunseed production is driven by three countries (CIS, EU and
Argentina – 49%, 19% and 11%, respectively), with the US a poor
fourth at 3%. While production has tripled in 20 years the low yields
and expanding area in the CIS has slowed the market growth. Yields
have expanded healthily in any case, although there was a lost
decade when CIS yields regressed rather than grew. Sunflower oil is
sold at a premium compared to other vegetable oils into to
Mediterranean and North African markets, where it is preferred as a
cooking oil. Global production at less than 40.0 MMT will grow to
50.0 or 60.0 MMT.
Each major vegetable protein economy produces a variety of
proteins locally as determined by their comparative advantage, and
the balance is either exported or imported. Since China is a major
importing vegetable protein economy, its S&D balance is
summarised here. Its domestic production of almost 60.0 MMT of
major oilseeds is dominated by soybeans (15), sunseeds (2.5) and
rapeseeds (12.5), as well as cottonseeds (12.5) and groundnuts (15),
the non-US name for peanuts. In addition, it imports a staggering
60.0 MMT of soybeans and 2.5 MMT of rapeseeds, crushing 100.0
MMT per annum. In the early 2000s, China imported only 20.0 MMT
of soybeans and had a major softseed crush capacity of 55.0 MMT, of
which 25.0 MMT was soybeans. At that time, the big four soybean
exporters (US, Argentina, Brazil and Paraguay) had a total crush
capacity of 100 MMT which has grown over the same 10-year period
to roughly 125 MMT, (US 45, Argentina 38, Brazil 40 and Paraguay 3)
while China’s grew from 25 to 100 MMT.
Softseed crushing is the process by which seeds are pressed
through a die. Heat, steam and solvents are used to extract the oil
from residual meal to form the two principal by-products and leave
the hulls and seed covering. One can imagine other softseeds that are
produced and used in different ways, such as peanuts, sesame seeds
and mustard seeds, which are consumed and processed or simply

business, comprehensively analyses the crushing of 10 major
oilseeds, 17 major oils and 12 major meals, including cottonseed oil,
fish oil, corn oil, palm and palmkernel oil, butter and lard. Local
tastes and GDDs drive the local markets, and deficits and surpluses
are imported or exported. Rapeseed oil is preferred for its taste in
Chinese cooking and it is by far the largest rapeseed market in the
world.
The complexity of the soybean business is perhaps best illustrated
by the soybean product tree (see Bell, David E., and Mary L.
Shelman, 2006, “Bunge: Poised for Growth”, Harvard Business
School Case 506–036, July), which shows that the crushing plant
complex is quite large and comparable to a petroleum refinery if all
the various streams are included. In North America and the EU, the
crushing plant will supply downstream processors such as Solae (a
Bunge DuPont joint venture) for further processing. In Brazil, the
industry is still evolving to develop the various processed product
streams and many of these crushing plants are truly biomass operations – for instance, the plant being built on 10,000 Ha of which 20 Ha
is the actual plant, bottling and bagging, trucking, warehousing and
logistics, and the balance is producing eucalyptus trees which are
harvested and used to power the plant and its various services.
What we should note at this point is these plants do not suddenly
appear, they are planned in advance and the crushing equipment is
ordered in advance. The storage facilities for vegoil are quite technical, and meals are not without their complexities due to their
physical characteristics. Fundamental analysis includes the forecasted change in crush and downstream capacity by location and
type of operation. Compared to petroleum refineries, they are cheap.
Impressive worldscale operations are built for US$0.2 billion rather
than US$2.0 billion. Within the study mentioned above, at that time
Bunge was the world’s biggest soybean crusher, and the expectation
for soybean crush evolution by geography is given. They expected
the 2010 crush of soybeans to look like US/Arg/Braz/EU/China as
52/25/30/17/25 (149 MT total), respectively, when in fact it looked
more like 45/38/40/12/76 (211 MT total), respectively. The forecast
missed both the size and geography of actual growth. The error was
–7/13/10/–5/51 (62) or 87/152/133/71/304 (142)% of forecast.
Although these would have been constantly revised by Bunge, it
demonstrates the ease of making a substantial error and consequent
difficulty of building for the future. In fact, the marketplace did
198
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 199
GRAINS AND OILSEEDS
generally underestimate China’s appetite for soybean imports and
the desire to crush them domestically, as it did the Chinese growth
story for all commodities.
We also have to remember that once capacity is built it is normally
run, in any industry, at any contribution to the bottom line that
exceeds variable cost. The different regional growth patterns imply
different rates of port development to move the commodities, as well
as different rates of growth in downstream and associated industries. A further unexpected agribusiness consequence, but one which
the petroleum business is quite familiar with, was the building of
strategic reserves of foreign currency held in commodities by China
– look at their enormous stocks of soybeans and oilseed rape, 16 and
6 MMT, respectively.
The Chinese domestic oilseed complex growth has been virtually
stagnant since the early 2000s growing from 55 to more than 58
MMT, within which soybeans contracted by 2 MMT, while rapeseed,
cottonseed and groundnuts increased. Soybean imports grew from
21 to almost 60 MMT, and rapeseed imports grew by more than 2.5
MMT, so that crush now stands at soy 61 MMT, rapeseed 15 MMT,
sunflower 1 MMT, cottonseed 10 MMT and groundnuts 7 MMT, for
a total crush of 96.0 MMT – the biggest in the world. Add to that the
24 MMT of oilseeds consumed other than through full crush (partial
processing), of which 11 MMT is soybeans, 3 MMT is cottonseed and
8 MMT is groundnuts, and we see a better picture of the 120 MMT
Chinese oilseed powerhouse, consuming far more than any of the
big three producers. In the early 2000s, they carried oilseed stocks of
almost 19 MMT in China, and in 2013 stocks stand at an estimated 24
MMT. The USDA estimates that if it costs US$100/MT to move
soybeans from Iowa to Chinese ports, it costs US$175 from Mato
Grosso in Brazil. This means the expansion of soybeans in Brazil is
disadvantaged at the farmgate by that amount, and this inevitably
leads to Brazil finding other uses for soybeans until transport efficiencies can be de-bottlenecked.
On the soybean demand side, 10 years is also a long time and the
rapidly changing face of Brazilian agribusiness is well illustrated by
the emergence of JBS on the world stage. JBS is the largest Brazilian
multinational food processing company, producing fresh, chilled
and processed beef, chicken and pork, and also selling by-products
from the processing of these meats. This has lead to a surge in
Brazilian soybean consumption domestically. In a decade, its
199
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 200
COMMODITY INVESTING AND TRADING
domestic meal consumption has grown by 5 MMT to 12.5 MMT.
Argentine meal consumption in the same period grew from 0.25
MMT to almost 2.0 MMT.
JBS has established itself as the largest global company in the beef
sector with the acquisition of several retail chains and food companies in Brazil and around the world, especially the 2007 US$225
million acquisition of US firm Swift & Company, the third-largest US
beef and pork processor, renamed as JBS USA. It leads the world in
slaughter capacity, at more than 50,000 head per day, and continues
to focus on production operations, processing and export plants,
nationally and internationally. With the new acquisition, JBS entered
the pork market, featuring an impressive performance in this
segment, to end the year as the third largest producer and processor
of this type of meat in the US. The acquisition expanded the
company’s portfolio to include the rights for worldwide usage of the
Swift brand. The following year, JBS acquired Smithfield Foods‘ beef
business, which was renamed JBS Packerland. JBS’s production
structure is embedded in consumer markets worldwide, with plants
installed in the world’s four leading beef producing nations – Brazil,
Argentina, US and Australia – serving 110 countries through
exports. In September 2009, JBS announced that it had acquired the
food operation of Grupo Bertin, one of three Brazilian market
leaders, consolidating its position as the largest beef producer in the
world. On the same day, it was announced that the company had
acquired 64% of Pilgrim’s Pride for a bid of US$800 million, establishing JBS’s position in the chicken production industry. In August
2010, it was reported that JBS was trying to sell some of the eight
slaughterhouses it owns in Argentina because of “scarce livestock
and export restrictions.” By 2011 they were attempting to gain
control of Sara Lee Corporation‘s meat business.
Brazil has aquaculture production targets of 1.0 MMT by 2015 and
10.0 MMT by 2020 from a base of 0.5 MMT in 2011. While this may be
too high to achieve by 2020, we can easily imagine them managing it
by 2025, again reshaping soya and (non-vegetable) protein flows. It is
worth looking back at Table 7.5 to understand the significance of this
number.
In 2003, the unthinkable happened in the soya world: there were
terrible crop yields in the US, Argentina and Brazil, all in the same
year. Forecasters expected a rising yield, but the US dipped from 2.56
200
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 201
GRAINS AND OILSEEDS
to 2.28 MT/Ha, Argentina from 2.82 to 2.36 and Brazil from 2.82 to
2.37. In 2002, Argentina and Brazil out-yielded the US for the first
time, and their combined production matched US. For the first time,
not only did global soybean production not grow, it dipped by some
10 MMT. This sparked an unprecedented rally which had long-term
effects on how the markets traded, who dominated them and how
the Chinese thought about their soybean strategy. In the author’s
opinion, this drop may be partly attributed to the illegal spread of
GM seeds in Latin America at a time when the technology was new
and certainly undeveloped for Latin American conditions. Critically,
it demonstrated that yield advancements came with increasing yield
variability and unexpectedly large sensitivity to weather variations.
The US saw 0.5 standard deviation changes in GDD’s give far bigger
swings in yield than history would have lead us to expect.
For those who follow freight markets, part of China’s soybean
importing strategy has been to add Chinese tonnage to the global dry
bulk market, since they are structurally short, causing a sharp downward correction in freight prices.
HOW ROTATION CONVERGES THE GRAINS
As a major source of income for trading companies and hedge funds
alike (see Appendix 7.1), and definable by excellent fundamental
analysis, we can “arbitrage” maize, wheat and soybean prices. In the
short run, one can reasonably expect these three commodities to
change price relative to each other, to reallocate or switch hectares
between crops and hemispheres. We can always bring more land
into production, but in Brazil, for example, that involves a year of
land clearance of indigenous plants before a year of growing rice and
clearing the land, and then a serious commercial crop can be started
in the third year. Table 7.9 shows an interesting view of the major
crop economies in a side-by-side comparison of total arable land flexibility and individual crop flexibility. The major opportunities with
existing resources, in terms of area, are all within Table 7.9. The
serious student should understand this one table representation of
flexibility in both percentages and individual crops as well as the
yield gaps presented in the various tables for the major crops, by
country.
The US and the EU-27 are the most economically responsive areas
or “rational actors” to relative price, by which we mean per-hectare

income. Since the early 1990s the US has planted as little as 32% and
as much as 41% of its 90.0 MHa of arable land to maize, 2–6% to
sorghum, 22–34% to wheat and 28–38% to soybeans. At the last
count, the US were at maximum on maize, 35% on soybeans and
minimum on wheat. This trend will continue with more ethanol
(maize) produced and less land available for wheat and soybeans.
Wheat area is the most switchable, and surged 3.0 MHa in 2003.
Soybean hectares surged almost 2.5 MHa in 1997 in response to the
Freedom to Farm Act. Over the 20 years, total land area only
increased by 6 MHa. With the threat (or reality) of E15, it is expected
there will be more maize at the expense of wheat.
By contrast, the EU-27 has 60.0 MHa in grains and oilseeds up by
almost 20.0 MHa's in 20 years, with maize swinging between 9% and
17%, wheat between 40% and 46%, barley between 21% and 34%,
rapeseed between 6% and 12% and sunseed between 6% and 14%. At
the last count, the EU-27 was close to maximum on wheat and rapeseed, average on sunseed and close to bottom on barley.
Argentina and Brazil till some 30 MHa and 46 MHa, respectively,
with each having grown from 15.5 and 30.5 since the early 1990s.
Argentina is more rotationally complex, with 10–17% maize, 2–5%
sorghum, 11–38% wheat, 31–68% soybeans and 6–19% sunseed.
Brazil is 28–46% maize, 3–11% wheat, 5–15% rice and 32–59%
soybeans. Latterly, Argentina has been in the middle on maize, at the
high end for sorghum, at the bottom end for wheat and all the way to
max on soybeans and at minimum for sunseed. Brazil was close to
minimum for maize, bottom end for wheat and rice and, like
Argentina, at max for soybeans.
China, with 103 MHa under tillage, is almost unchanged in area
since the early 1990s (+5 MHa), and can swing 22–33% on maize, 23–
32% on wheat, 29–34% on rice, 7–11% on soybeans and 5–8% on
rapeseed. At the last count, it was max on maize (to blend with
imported soybeans), minimum on wheat, rice and soybeans and
close to max on rapeseed. The main China growth story is meat
production – pork and chicken – with high FCE. A high FCE requires
a singular focus on “maize-plus-soymeal” diets, for physical flowability or product handling as well as nutrition.
India, with more than 90 MHa in tillage, swings only 31–34%
wheat, 48–57% rice, 4–12% soybeans and 6–9% rapeseed. Food security points to more wheat over time but much of this is going to go to
203
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 204
COMMODITY INVESTING AND TRADING
more intensive large-scale farming. Indian productivity per hectare
has only one way to go: up.
The CIS/FSU has some 85 MHa under tillage and dismal yields.
Maize farming should be declining and swings 2–9% (currently at
max), wheat 53–64% (currently in the middle), 16–38% barley
(currently at the low end) and 5–17% sunseed, which is now at the
high end. We expect to minimise barley and maximise sunseed and
wheat for the foreseeable future.
It would be nice to make a big deal of Argentina and Australia, but
this is not realistic. They do not have the land mass or yields and so,
even if Canada is max on rapeseed at 1.0 MHa, it simply does not
make a global difference. At this time, it is max on rapeseed and
minimum on wheat. Australia is dryland farming with sporadic rain,
so unreliable. The “call-like” planting of Australian wheat means
they will continuously plant, from year to year, and hope for rain just
as Texas does in the US.
Area times yield equals production. The most populous countries
have the land pretty much tapped and China has done tremendous
work on yield. The baton falls to India to improve crop husbandry.
Brazil has land in abundance but infrastructure is so tight and expensive that it is likely to continue its domestic trend toward more meat
and aquaculture production. This would expand its export capacity
by displacement, just as it now moves vast quantities of sugar by
container to the export market. The major opportunities with existing
resources in terms of A are all within Table 7.9 and the serious student
should understand this one table representation of flexibility in both
percentages and individual crops as well as the yield gaps presented
in the various tables for the major crops, by country.
SUMMARY OF MAJOR TRENDS AND SWING FACTORS FOR
THE FUTURE
If one thing alone has changed the grain markets completely since
the early 1990s and is likely to continue to do so, it is undoubtedly the
US corn-based ethanol programme. It remains phenomenally difficult to change commercial US law once it is in place other than by
incremental amounts. If cellulosic ethanol arrives it will change the
world forever and cause grain prices to collapse. However, it
appears to be no closer in terms of substantial economic reality than
we saw in the early 2000s.
204
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 205
GRAINS AND OILSEEDS
If there is a second thing that has also changed the grain markets
completely during this period, it is the manner and rate at which
CPGs are growing to dominate our increasingly urbanised food
consumption. At the time of writing, China’s Shuanghui
International has just bought Smithfield Foods, the huge US-based
but globally active pork and meat company, for US$4.7 billion. The
need for modern food processing safety, branding and packaging,
and all the required supply chain management skills, has rendered it
more cost effective “to buy it rather than build it”.
If there is a third thing that must happen over the next few years, it
is the intensification of agriculture – for the cost of bringing more
area into production has become much more expensive than most
had anticipated.
Since maize combined with soybean meal is the cornerstone of
modern animal (and soymeal for aquaculture) nutrition, much more
grain will be consumed in Brazil and exported as meat. China and
the US have some 34 MHa under maize, and both will increase area.
Also, Chinese yield will move towards the US (there is a 3 MT/Ha
gap, see Table 7.3), just as China did with the EU in wheat (see Table
7.6). The maize market into the 2020s will remain fundamentally
tight and expensive. E15 will take more corn to the fuel tank,
although there are some real costs being discussed at the retail petrol
station level where the retail supplier is pushing hard to stay at E10
or go to E15, but not carry both. This would require adding pumps,
tanks, trucks and re-branding – all expensive items. Brazil will export
more maize than the US consistently. The only two things that can
cause maize demand to break to the downside are a dramatic u-turn
in US energy policy (1:100) or a breakthrough in cellulosic ethanol
(1:50). Even a dramatic fall in crude oil prices would only stimulate
maize demand for the gasoline pool as it worsens the economics for
cellulosic ethanol. Economics says Brazilian ethanol should continue
to flow in ever-greater quantities to the US, but it may not become a
political reality.
It is ironic that the CIS/FSU has a higher barley than wheat yield,
something almost impossible in terms of modern farming. The
CIS/FSU has the greatest potential to increase yield through intensification and plant breeding, and has some 49 and 14 MHa under
wheat and barley, respectively. Any area reductions will be offset by
increased commercialism of these two markets inside Russia, from
205
07 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:57 Page 206
COMMODITY INVESTING AND TRADING
farmgate to consumer. Wheat will continue to assume the role of
primary determinant of grain prices globally as its volume is
increasing while US maize volumes decline, net of ethanol. India will
become a consistent importer of wheat and withdraw from the
export market into the early 2020s.
The Chinese (Asian) and Indian (sub-continent) appetites for soya
will continue as meat and fish demand increase. The CPG intensification of their food systems will also increase, along with urbanisation
and wealth. At 11 MMT of soybeans and 7 MMT of rapeseed, softseed production in India is growing rapidly, and significant imports
will come in time.
We have been waiting for palm oil production to reach a
maximum in Malaysia and Indonesia, but it continues to increase. At
some point this must happen and will create more pressure for
global soybean area to increase.
In terms of AYP, we will continue to see area expand slowly but
yield to expand at more impressive rates (see Table 7.1). In fact, the
author is optimistic it will be much higher.

Coal
Jay Gottlieb
This chapter will provide the risk management professional with an
orientation to understand the oldest and oddest of energy markets:
coal. It will explain the physical characteristics of coals, coal market
structure and dynamics, and the coal price indexes and trading
venues used for transacting financial derivatives. The chapter will
also cover key developments in the fundamentals of coal along with
an understanding of the broad range of instruments available to
manage risk in that market, and will provide an overview of market
drivers and their interaction, as well as offer an initial reference for
the detailed data needed to analyse the coal market.
OVERVIEW
Coal seems to be the unwanted stepchild of the energy world: dirty,
old-fashioned, not really popular anymore. Who cares? On the other
hand, those who do care a lot often seem to echo the famous words of
a White House adviser on energy and the environment:
“A Harvard University geochemist who serves as a scientific adviser
to President Obama is urging the administration to wage a ‘war on
coal.’
‘The one thing the president really needs to do now is to begin the
process of shutting down the conventional coal plants,’ Daniel P.
Schrag, a member of the President’s Council of Advisers on Science
and Technology, told the New York Times. ‘Politically, the White
House is hesitant to say they’re having a war on coal. On the other
hand, a war on coal is exactly what’s needed.’”1
Trends in worldwide coal consumption indicate that Professor
Schrag’s war is going badly:
207
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 208
COMMODITY INVESTING AND TRADING
“Coal consumption grew by 2.5% in 2012, well below the 10-year
average of 4.4% but still the fastest-growing fossil fuel...Coal reached
the highest share of global primary energy consumption (29.9%)
since 1970.”2
Coal has driven global development since the British industrial revolution, beginning in the 18th Century with the harnessing of
increasing amounts of coal-fired steam power for transportation and
steel production. The role of coal-fired steam in transportation and
manufacturing along with the use of coking coals in the production
of steel is familiar. While other fossils remain a big part of people’s
daily lives – petrol for cars and natural gas for home heating and
cooking – coal has largely receded from view. It works away quietly
in the industrial background. While coal is no longer used locally for
transportation or building heat, it is still consumed as a key component in steel and cement production and fuels around 40% of the
world’s electric power generation.
Coal is found abundantly around the world, is relatively easy to
produce with existing mining technologies and can be transported
through a wide variety of modes, such as conveyor belt directly from
mine to power plant, or through combinations of truck, rail, barge
and ocean-going freighter. As transportation infrastructure developed around the world since the 1960s, prices for bulk transportation
declined and coal changed from a commodity with only a local
regional reach and economics to one that is traded similarly to other
higher-value energy commodities, flowing around the world from
production areas to wherever it commands the highest value in
consumption. Along with the explosion of transportation options,
coal consumers have become much more sophisticated in managing
their power plants to run on a greater variety of coals, adjusting for
physical and chemical differences in coals from divergent sources.
The major exporters of coal are Indonesia, Australia, South Africa,
Colombia, US and Russia. China and Europe are the major
importers. While the exact numbers will of course change from year
to year, the major participants will not.
CHARACTERISTICS OF COAL
So, let us return to the question, “what is coal?” It is an energy-rich
source of carbon that is relatively easy to find, mine and transport,
but is also bulky and heavy relative to its energy value. Also, coal
208
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 209
COAL
comes with many other non-carbon components that must be
controlled to limit pollution and other unwanted emissions from
power production and other consumption.
Coal is a combustible sedimentary organic rock consisting of more
than 50% carbon by weight. It is a fossil fuel derived from plants that
grew in swamps that were later buried by sediments. Geological
processes compressed and heated the plant remains over vast
periods of time, producing various ranks (or categories) of coal.
With increasing rank, coal becomes harder, brighter and the heat
content is higher. The ranks from lowest to highest are: peat,
brown coal, lignite, sub-bituminous, bituminous and anthracite
(listed in Table 8.1).
While coal is chiefly comprised of carbon, hydrogen and oxygen,
it also contains varying amounts of sulphur, nitrogen and other
elements. Coal quality varies a great deal and is priced based on
these characteristics. The heat content is the key value of the
commodity for electricity generators and cement producers, while
other characteristics are important for steel producers. Disposing of
the non-desirable components, particular sulphur and nitrogen,
adds cost to the consumption of coal.

COMMODITY INVESTING AND TRADING
Heat content is measured as the heat produced by combustion of a
specified quantity of the fuel when burned at a constant pressure
under controlled conditions for water vapour. It is measured in
terms of either British thermal unit (Btu) per pound in the US or kilocalorie per kilogram (kcal/kg) internationally. In all cases, higher
heat content is preferable to lower.
Thermal coal fires power generation plants, and metallurgical (or
met) coal is used for steel production. We will now look at which
coal qualities are of importance in thermal and metallurgical
consumption.
Thermal coal
Most coal is used for the energy content within the volatile matter
and the fixed carbon. These coals are generically termed “thermal”
(or steam) coals and are mostly used for electricity generation. A
typical Australian thermal coal contains 6,080 kcal/kg of usable
energy (net as-received energy) or 25.46 megajoules/kilogram
(MJ/kg) of coal. Electrical energy (power) is measured in watts
which are joules per second, therefore one kilowatt hour of electricity
(one unit) converted from coal at 35% efficiency requires 10.286 MJ of
coal energy every hour, or 0.404 kg of coal. Other thermal coal uses
are the calcination (breakdown by heat) of limestone to form cement
for construction industries or lime for agricultural purposes.
Hospitals and other institutions use coal for process heat, as do abattoirs, wool sours and timber-drying processes.
Metallurgical coal
For steel and other metallurgical production, certain bituminous
coals are particularly suited to release gaseous components, called
volatile matter, when heated to extremely high temperatures in the
absence of oxygen. When these special bituminous coals swell on
heating above 350 0C and release their volatile matter, they leave
behind a hard porous carbon residue called coke. These coals are
called coking coals and are limited in their occurrence around the
world. Coking coals are primarily used to make coke that, under
high temperatures, reduces metal oxides to metals. This process
occurs when the coke is combined with the metal oxides at elevated
temperatures. The carbon from the coke combines with the oxygen
from the metal oxides to produce carbon dioxide, liquid metal and
210
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 211
COAL
residual ash (slag). The coals most suitable for producing coke
command the highest prices on the world market.
Sulphur content is always undesirable. Creating air pollution
when the coal is burned, sulphur emissions must be controlled with
expensive technologies. Laboratory analysis of sulphur content as
percentage of total weight of coal is typically adjusted for the heat
content of a ton of the coal for pricing purposes, as regulatory standards are based on how much sulphur is emitted per ton of coal
burned.
High-rank coals are high in carbon and therefore heat value, but
low in hydrogen and oxygen. Low-rank coals are low in carbon but
high in hydrogen and oxygen content.
Transportation
More than any other energy commodity, transportation costs are a
major component of the cost of fuel delivered to the end-user. This is
a simple result of coal’s high bulk and weight relative to its value.
The high cost of transportation and rigidities in the transport infrastructure impact the markets for coal. Coals are typically priced
either free on board (FOB) at mine origin, or cost, insurance and
freight (CIF) at the consumer’s destination, with either the consumer
or producer responsible for arranging and paying for transportation
from or to that point. There are no intermediate collection points and
few wholesale marketing points. Train shipments are difficult, if not
impossible, to re-schedule and re-direct, so there is very little trading
of physical coal once it is en route to an ultimate destination, unlike
the vast amount of trading of oil tankers. Seaborne coal markets are
where the most active trading occurs, because of the greater flexibility and relative low cost of moving a bulky item across the water
versus across land.
Coal mines are either surface (open pit) or underground.
Transportation from the mine can be done through a number of
modes, but again the low value-to-weight ratio makes minimising
the physical handling of coal the key to cost efficiency in transportation. Depending on distance and mode of transport, transport costs
for delivered coal range from 20–70% of delivered price to the ultimate consumer, a major component of the total cost of coal
procurement.
Coal can be moved directly from source to end-user via truck for
211
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 212
COMMODITY INVESTING AND TRADING
distances of less than 100 miles. For longer distances, rail or waterborne transport is typically used. Coal can also be trans-shipped
from rail or truck into river barges or ocean-going vessels. For other
than international export, no more than two trans-shipments would
be used, as it is important that transportation mode changes add as
little cost as possible. Therefore, coal goes from mine to end-user
with few intermediate transactions.
Historically, coal sold under long-term supply contracts with less
trading than other commodities – due to high capital costs mirrored
on both the production side (mine and transportation development)
and the use side (power plant construction). Since many of the
mines, transportation networks and generation plants have been put
in place and their capital costs are amortised, the economics allows
for shorter deals. In addition, consumers have learned to be much
more flexible in sourcing, which enables coals to compete among
each other and against other fuels. Consequently, markets have
become more dynamic. Trading and risk management tools have
also grown to match that flexibility. An increasing proportion of coal
is sold on the spot market and priced off of indexes. This is what has
stimulated the growth of derivatives trading.
Cheaply mined and having relatively low heat content (and also
low sulphur content), Powder River Basin coals are shipped by rail
from Wyoming to west coast ports and then on to Asia. Eastern US
coals can change modes several times, from mine by rail or truck to
river barges and then out to Europe through loading on ocean-going
vessels in the New Orleans area, or directly by rail to ports on the east
coast. Once sea-borne, coals from Australia and South Africa
compete with the US coals for markets in Europe and Asia. The
consumer purchases the coal based on a limited number of heat
content and quality variables against the price delivered to their
power plant. Thermal coal has become for the first time a truly world
commodity, a fact that is reflected in the growth of derivatives
trading.
Bituminous coal is typically much more expensive to mine, has up
to 50% greater heat content and thus significantly lower transportation costs, and can be environmentally friendly, commanding higher
price at the mine. As mentioned above, sub-bituminous coal, such as
from US Powder River Basin, has lower heat content and transportation costs as much as 50% greater – with long, overland rail
212
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 213
COAL
transportation to end-users or export terminals – but has low mining
costs due to thick seams of easily accessible coal through surface
mining, and often has lower sulphur content. This makes it
extremely competitive, even in world markets, and significant export
capacity on US west coast is under development.
MARKET STRUCTURE
Worldwide, most coals are priced on a per ton basis. In the US,
however, many utilities prefer to buy on a price based on heat
content rather than weight, in million Btu (MMBtu).
Prices are measured by many indexes that are transparent and
reliable, and have allowed the growth of derivatives trading based
on them. In the past, published prices rarely changed and were
totally unreliable for any contracting or trading. Little spot trading
occurred and long-term contracts included negotiations of many
factors, particularly free supply options for the buyer, which made
price comparison across time or contracts meaningless. For these
reasons, active physical and financial trading of coal was slow to
develop, but has become fully integrated into the energy risk
management environment.
A joint venture between an energy market news organisation,
Argus Coal Services, and a coal industry economic and management
consulting firm, IHS McCloskey, produces the API indexes, which
are the standard industry benchmarks. The main focus for activity in
the coal derivatives market is the API 2 index, which consists of an
average of the two firms’ price assessments for coal imported into
Amsterdam, Rotterdam and Antwerp, and includes CIF. Another
major index is API 4, which is the benchmark for coal exported from
Richards Bay in South Africa and also incorporates CIF. Argus estimates that more than 90% of the world’s coal derivatives are priced
against these indexes. The list below describes the key indexes used
for international physical and derivatives coal business.
❏ API 2 index: the industry standard reference price used to trade
coal imported into northwest Europe. The index is an average of
the Argus CIF Rotterdam assessment and McCloskey’s northwest European steam coal marker.
❏ API 4 index: the price for all coal exported out of Richards Bay,
South Africa. The index is calculated as an average of the Argus
213
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 214
COMMODITY INVESTING AND TRADING
FOB Richards Bay assessment and McCloskey’s FOB Richards
Bay marker.
❏ API 5 index: the price for exports of 5,500 kcal/kg net as received
(NAR), high-ash coal from Australia. The index is calculated as
an average of the Argus FOB Newcastle 5,500 kcal/kg assessment and the equivalent from IHS McCloskey.
❏ API 6 index: this index represents 6,000 kcal/kg NAR coal
exported from Australia. It is calculated as an average of the
Argus FOB Newcastle 6,000 kcal/kg assessment and the equivalent from IHS McCloskey.
❏ API 8 index: the price for 5,500 kcal/kg NAR coal delivered to
south China. It is calculated as an average of the Argus 5,500
kcal/kg cost and freight (CFR) south China price assessment and
the IHS McCloskey/Xinhua Infolink south China marker.
The publishing schedule for these widely used indexes are as
follows:
❏ Weekly average coal price:
❍ Northwest Europe (CIF ARA) API 2 index;
❍ South Africa (FOB Richards Bay) API 4 index;
❍ Australia (FOB Newcastle) API 5 index;
❍ Australia (FOB Newcastle) API 6 index; and
❍ CFR south China API 8 index.
❏ Monthly coal price: API 2, API 4, API 5, API 6, API 8 indexes; and
❏ Daily coal price: API 2, API 4 indexes.
These prices are available exclusively through the Argus/
McCloskey’s Coal Price Index service.
FINANCIAL MARKETS FOR COAL
Virtually all markets are served by multiple over-the-counter (OTC)cleared standardised derivatives contracts. Multiple platforms offer
products on the same indexes. OTC trades are cleared on two
competing platforms: CME/Nymex and the Intercontinental
Exchange (ICE). The types of coal futures for each exchange are listed
below (as of June 2013). The exchanges also list options and strips for
most of these futures.

rail improvements or development of export terminals.
❏ Consumption: emission of carbon, sulphur oxides and nitrous
oxides on the consumption side; retrofitting of new control technologies and purchase of emission allowances and credits.
Supply and trade
Minerals mining companies focused primarily on coal extract the
majority of the produced coal. Such companies range from national
producers to international corporations, as well as many smaller
companies. While it used to be very common, particularly in the
Appalachian region of the US, for companies to be formed to own
and operate just a single mine, much of the industry has taken
advantage of economies of scale that have resulted in a greater
concentration of ownership in larger corporations. Consequently,
short-term spikes in price can occur due to strikes, labour shortages,
transportation bottlenecks and mining problems at the larger mines.

tries outside the US have increased by around 200% since the late
2000s. These dramatic rises in cost vary across production areas and
are due to a wide variety of reasons. The main impact has been to
increase the integration of worldwide coal markets as producers look
for more extensive markets and consumers search for competitive
purchasing opportunities.
Figure 8.1 shows the changing landscape of the top global coal
exporters. Almost half of Australia’s exported coal goes to metallurgical use, mainly in Asia and Europe, with Japan, India, China and
South Korea being the main Asian importers. Japan is also the largest
buyer of Australian thermal coal. The US and Canada export significant quantities of metallurgical coal, but thermal coal comprises
most of Indonesia’s rapidly growing export volumes. China,
South Korea, India and Japan are the largest importers of US coal.
Figure 8.2 shows the distribution of recoverable reserves for coal
globally, while Figure 8.3 displays the trends for the largest
importing countries.
Consumption
While there are other important trends in coal demand, such as
continued growth in India’s consumption and imports, China alone
has dominated global consumption and demand growth. Again

quoting from BP, “Statistical Review of World Energy” (June 2013)
regarding 2012 annual growth in coal use:
“Consumption outside the OECD rose by a below-average 5.4%;
Chinese consumption growth was a below-average 6.1%, but China
still accounted for all of the net growth in global coal consumption,
and China accounted for more than half of global coal consumption
for the first time. OECD consumption declined by 4.2% with losses
in the US (–11.9%) offsetting increases in Europe and Japan. Global
coal production grew by 2%, with growth in China (+3.5%) and
Indonesia (+9%) offsetting a decline in the US (–7.5%). Coal reached
the highest share of global primary energy consumption (29.9%)
since 1970.”
Thermal coal consumption in the US has decreased since 2008
compared with increasing consumption in Asia and Europe. In the
US, natural gas continues to displace more and more coal generation
due to the costs of upgrading old coal plants to meet ever-higher
emission standards, and the low cost of gas due to greater expansion
of supply.
The relationship between natural gas prices and coal prices for
power production has driven coal markets like never before. The

glut of natural gas in the US in 2012 drove natural gas prices to a level
where, in July 2012, for the first time in history US electricity production from gas-fired plants was equal to that of coal-fired plants.
Contrast this with the early 1990s, when coal represented more than
50% while gas represented roughly 5%. At prices above US$3.50/
MMBtu for gas, coal becomes competitive again. Gas-fired power
displaced US coal in the international markets, where the cheap coal
significantly increased European coal-fired generation at the expense
of their natural gas plants.
China’s consumption growth comes largely from increasing
power generation. China has large domestic coal reserves, but it will
always take advantage of low import prices and significantly
increase imports appropriately. Since US demand has been down
due to the explosion of inexpensive supplies of natural gas, China
has imported US and other coals while reducing domestic production. When demand and prices increase in the US domestic markets,
China will rely on its own production again.
PANEL 8.1: FUEL TO POWER SPREADS
A key ingredient in most liquid derivatives markets is the trading of spreads
between one instrument and another. In effect, most commodity trading is
based on the differential between two (if not more) prices. Few traders take
on outright risk, but most do choose very specific relationships where they
have developed expertise and expect that they can both recognise certain
trends before the market has fully taken them into account and can, in any
event, minimise the risk exposure made by each trade.
In options trading, there is a whole unique vocabulary describing the
various types of spreading between puts and calls on various strike prices
for the same security or commodity. Often, commodity futures spreads are
built on assessments of the likely trends in differentials between various
contract months in the same commodity. Classic commercial hedgers
spread the exposure between long and short positions for the same
commodity for the same delivery period, with one side being in the actual
purchase or sale of the physical commodity with an offsetting derivatives
position. In theory, whatever loss accrues on one side should be offset by
a corresponding gain on the other, keeping the producer, consumer or
merchandiser of the actual commodity protected against swings in the
market price of the commodity. Hedging thus frees up the firm to focus on
operational and marketing efficiencies rather than worrying about its business being disrupted by volatile price movements. This is, of course, in
theory. In practice, the “basis” of the differential between the underlying
220
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 221
COAL
physical and the financial derivative must be managed closely. Hedging is
often called an exchange of absolute price risk exposure for “basis” risk
exposure.
Most pertinent to coal are the spreads between inputs and outputs in a
commodity production process. The classic spreads are the soybean
“crush”, whereby trades are made on the differentials between the raw
soybean inputs which are crushed to make soybean meal and soybean oil,
with each having their own derivatives. With the advent of petroleum
derivatives trading, the petroleum “crack” spread became a key differential, measuring the cost of raw petroleum being refined into heating oil and
gasoline. Since petroleum refiners often had catalytic cracking units, and
“crack” is similar to “crush”, the petroleum “crack” was the logical new
name.
With the advent of electricity, natural gas and coal trading, the derivatives world added the “spark” spread, the differential between natural gas
fuel prices and electricity output prices. For coal-fired plants, the equivalent spread is the “dark” spread. Both of the spark and dark spreads can be
called “dirty” when they do not incorporate the cost of purchasing carbon
credits for emissions created by the plants.
In all these input-to-output spreads, financial traders develop standardised relationships describing the amount of each input required for each
unit of output. As the reality for each bean-crushing operation, each oil
refinery or electric power plant will vary from these standard trading
models, the hedging/risk management teams for those operators will
adjust their trades accordingly.
For a simple example of a dark spread calculation using US measurement units, the spread is measured by:
Spread = [Power price (US$/MWh)] – [Coal cost (US$/ton) +
Transport cost (US$/ton)] x [Heat rate of generator (MMBtu/MWh) ÷
Heat content (MMBtu/ton)]
where MWh is megawatt hour, heat rate is the rate at which the electric
generator converts heat from the coal combustion into power, measuring
the efficiency of the generating unit, and heat content is how much heat is
produced by burning a ton of that coal.
Unlike spark spreads, which are calculated using natural gas costs and
on-peak power prices, dark spreads often use a combination of on- and
off-peak power prices. This combination (referred to as the flat price)
reflects the different role that coal-fired generators play in the supply stack
of a particular electric system. Coal-fired generators have traditionally
served as base-load generation. They run throughout the day and night.
The combination of on-peak (during the day) and off-peak (nights and
weekends) power prices reflects this role.
In addition, as gas-fired plants are typically more efficient than coal,
typical spark spread heat rates correspond to an efficiency of around 0.5
(50%), while dark spread heat rates are near efficiencies of 0.38 (38%).

CONCLUSION
Typical production cost increases in the major exporting countries
other than the US have increased by about 200% since the late 2000s,
resulting in the integration of worldwide coal markets.
Different coals compete with each other through a sometimescomplex value optimisation, combining quality, suitability, location
and cost of transport. Quality differentials continue to play a bigger
role in import decisions for coking coal because they play a bigger role
in the suitability for various steel plants. This contrasts with steam
coal, which is basically just “heat” and is very interchangeable. There
are sufficient known and accessible reserves of met-quality coal;
however, due to the increases in production costs, prices have to rise
to bring them to market. Therefore, if demand for steel production is
sufficient, met coal prices will rise to meet the input demand.
Demand drivers are factors that move electricity demand such as
weather, economic growth and, to some extent, the price of
competing fuels including natural gas. Met coal demand depends
directly on steel production.
Multi-year coal contracts have been in a long process of evolution
since the early 1990s. It used to be fairly easy to describe typical terms
and conditions, but this is no longer the case as there are many types
differing within countries and from country to country.
Coal remains the single most important fuel for generating electricity worldwide. Traditionally, coal has been by far the cheapest fuel
for generating electricity. The other cheaper form is hydropower,
which is strictly limited by geography and annual weather conditions.
However, due to technological improvements in extracting natural
gas, that fuel has become consistently competitive to coal on price.
Furthermore, natural gas is less carbon-intensive than coal, its
burning produces fewer undesirable emissions and the capital costs
of building natural gas-fired generation are much less than for coal.
Therefore, coal has lost significant ground to natural gas. Due to its
abundance and the high level of installed generating capacity,
however, coal will continue to play a significant role in electricity
generation.
Since the beginning of the industrial revolution, coal has been – and
continues to be – the workhorse of the energy world. The coal
marketing chain from production to final consumer is typically much
less diverse and complex than other commodities. Coal also has a
222
08 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:58 Page 223
COAL
much lower value per weight than other commodities. Also, industrial organisations are the exclusive end-user consumers for coal. The
high proportion of transportation costs and less-diverse end-users
result in few transactions from mine-mouth to final consumer.
Therefore, among the major energy commodities, coal markets have
been the slowest to adopt financial derivatives. However, coal has
become a full member of the energy risk management jigsaw.

Farmland as an Investment
Greyson S. Colvin and T. Marc Schober
Colvin & Co. LLP
Although oil, metals, grains and financials are commodities key to
making the world go round, only farmland has no substitute.
Everyone has to eat in order to survive, and the production of almost
all food can be traced back to farmland. Demand is growing for farmland as the world’s population and global need for food increases.
However, what many do not realise is that the supply of farmland is
not changing, thus creating a severe imbalance in its supply and
demand.
Over the long term, farmland will provide a steady stream of
income and capital gains due to the increasing global demand for
agricultural commodities, driven by the rising world population,
rapid growth in emerging markets and continued demand for
ethanol and bio-fuels.
To understand it properly, we have to ask what exactly is farmland? The definition of farmland or agricultural land is the land
suitable for agricultural production, both crops and livestock.
According to the United Nations Food and Agriculture Organization
(FAO), there are three primary types:
1.
2.
3.
arable land: land under annual crops, such as cereals, cotton,
other technical crops, potatoes, vegetables and melons; also
includes land left temporarily fallow;
orchards and vineyards: land under permanent crops (eg, fruit
plantations); and
meadows and pastures: areas for natural grasses and grazing
of livestock.
229
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 230
COMMODITY INVESTING AND TRADING
For our purposes, we will generally focus on arable land or row crop
farmland that produces grains planted in rows harvested each year,
including corn, soybeans and wheat. These are the grains that are
(and will be) needed to feed the world’s growing population. We
will also look at farmland located in the US, since it has some of the
best producing farmland in the world, as well as the most advanced
farmers and farming technology, the most developed infrastructure
and uses the most leading technologies.
According to the Natural Resource Conservation Service (NRCS),
there are 12 recognised types of soil in the world. Of these, the most
naturally fertile are mollisols, which is suitable or very suitable farmland. Mollisols are generally found in only four places: in the Pampas
Region of Argentina, the Steppes of Ukraine and Russia, areas of
Northeast China and the Grain Belt of America. Mollisols make up
only 7% of the ice-free land in the world and are the best soils for
farming because they contain large quantities of organic matter.
Mollisols found in the Midwestern US are the best for agriculture
due to the grasslands formed thousands of years ago. These prairies
produced strong and fertile soils because each year the grasses (and
animals) would break down, with nutrients in the organic matter
decomposing into the ground. Once the Wisconsin Glacier retracted
from Illinois and Iowa, great dust storms blew fertile silt on top of the
young land, making it ideal for crop production.
However, in terms of percentage of land area, not very much of
the planet is actually appropriate for farming. Once you remove
places that are too cold or too wet, the deserts, the forests, the bad
soils and every other strange place that cannot host a decent haul of
crops, there is not much left over. However, while America has 5% of
the world’s population, half of its land is suitable for cultivating and
growing crops. In comparison, China has 20% of the world’s population but only 7% farmable land, according to the FAO.
Under the rule of law, US farmland cannot be hijacked by a totalitarian government or organised crime (yes, organised gangsters do
terrorise and control some farms in the Ukraine and Russia), and the
US Midwest Corn Belt sits in the optimum climate for production.
When coupled with modern technology, the US farmer’s work ethic,
excellent soil and infrastructure for transporting crops, the US is
unsurpassed for production.
All farmland is not created equal and no two properties are the

same. The ability of the land to produce profitable crops is part art
and part science; however, at the end of the day, so is analysing and
valuing farmland. This chapter will therefore cover the following
factors that drive the fundamental investment rationale for farmland
investments.

❏ Cash returns: farmland is a performing asset, generating modest
cash returns of 4–6%, depending on location and crop.
❏ Sustainable asset: farmland improves in productivity over time
when well managed.
The chapter is organised into the following sections: the first will
examine value creation and investment in farmland, before we delve
into renewables and their impact. The next section details production
and its limitations, and we finish with an investigation into global
farming.
VALUE CREATION AND INVESTMENT
Value creation from farmland
Arable land for farming has been valued since the first crops were
domesticated. Farmland creates multiple commodities: wheat, corn,
animal products and meats, and even wind energy if a landowner
chooses to lease out part of their land to host a wind turbine. An
investment in farmland can provide a steady stream of income from
demand for agricultural goods, driven by the rising world population
and rapid growth in emerging market consumption. The continued
demand for ethanol and bio-fuels also puts upward pressure on crop
values. Demand for agricultural commodities is outpacing supply,
which positions farmland for long-term appreciation.
We should look at what makes something valuable as a
commodity; is it, or does it offer, a broadly desired marketable item?
Is it something that would be dearly missed if it disappeared from
the worldwide market? In addition to being an end-user item, can
something also serve as an investment vehicle?
Farmland as lease property
A farmland owner who does not intend to operate the farm often
monetises the land’s value by leasing. A rental lease, in this case, is an
agreement between the landlord and the farmer of the property.
Often these agreements are legally binding documents drafted by
attorneys, but can be as vague as a verbal commitment (in which
case, it may be as solid as the paper it is written on).
Leases span all different lengths of time, from one year to the life
of the property, but in the Midwestern US they are often for between
one and five years. Farmers aggressively seek leased land for their
232
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 233
FARMLAND AS AN INVESTMENT
operations in order to expand and capture economies of scale
without increasing the most expensive element of production: the
land. Leased land allows farmers to spread equipment and other
fixed operation costs over more acres to increase profit margins, and
also allows them to increase income by farming more acres.
There are several possible lease options available to a landlord, but
any of them should return roughly a third of all revenues generated
from the land per year. There are three main types of farmland
leases:
cash rent: fixed rate per acre per year;
wner shares in the expenses and profits; and

landowner from taking on crop or credit risk from the farmer. The
landowner does not have to worry about drought or the rate of crop
growth. Land across the Midwest is typically leased at 4–5% of the
market value of the land; target farmland for investment that can be
leased for 5% or greater is recommended. Farmland in other regions
of the US can have lower lease rates as a percentage of value due to
the commodities produced and other factors affecting the value,
such as potential development.
Farmland as an investment
Farmland has a proven record – it has been one of the top performing
investments over the last 100 years. In the 20th century, farmland
only decreased in value three times: during the Great Depression, the
inflation crisis of the early 1980s and in the housing crisis of 2008/09.
The US farm sector has a healthy balance sheet and, as mentioned,
debt-to-asset ratios are low. Unsurprisingly, farmers historically
have been the main buyers of US farmland and do not buy intending
to flip for profit but rather to hold for decades or generations,
keeping the land in the family. Farmland is the most valuable asset a
farmer can own, which leads most to reinvest a significant part of
their crop and livestock revenue back into the purchase of additional
farmland to expand their operations.
It is also important to understand that farmland values per acre
are essentially a function of revenues generated per acre. Revenues
are mainly dictated by two variables: price of the commodity and
yield per acre. In the 20th century, grain prices were fairly stable
while production increased a few percentage points per year, on
average. The increase in production allowed farmland to become one
of the most stable and consistent asset classes.
Despite three downturns over the last 100 years, farmland returns
in the US are historically one of the best investment vehicles,
comparing favourably with more traditional assets such as stocks
and bonds. Table 9.1 clearly shows the stability of farmland. Bear in
mind, this includes crop years and/or regions that were wiped out
or suffered severely diminished yields due to drought, flood and
other disasters.
In 2012, the Federal Reserve Bank of Chicago reported that farmland values grew by 16%, the third largest increase in the previous 35
years. Despite the worst drought in over 55 years, high commodity

prices and record farm incomes drove demand for agricultural land.
Survey respondents anticipated that the momentum would continue
over the next 12 months based on the record income expectations for
2013. Iowa farmland values led the pack, with a 20% return in 2012,
followed by Illinois and Michigan with an 18% annual return. This
was during a time many considered recessionary.
One of the most attractive attributes of farmland is income
realised from rental. Since 1967, rural cash rents have yielded
roughly 5.7%, according to the USDA (this was calculated by the
authors using historical data from: http://usda.mannlib.cornell.
edu/MannUsda/viewDocumentInfo.do?documentID=1446). This
compares very favourably to Treasury bonds and other incomeproducing assets. The cash rental contract is typically prepaid, so the
investor does not have to take operational or credit risk from the
farmer. Society will undoubtedly be drastically different by the mid21st century, but the US farmer will still be leasing farmland to raise
livestock and crops.
Farmland also provides investors with the chance to diversify
from traditional investments, which makes it an excellent asset to
balance a portfolio and offset financial and commercial real estate
market volatility. Farmland has always shown a positive correlation
to the Consumer Price Index (CPI), exceeding stocks, bonds and nonfarm real estate.
Farmland is frequently compared to investing in gold because of
its characteristic as an inflation hedge. However, unlike gold, farmland also produces a stable income stream, and as a consequence it
has been described as “gold with yield.” Gold does not stock-split or

pay dividends; you just hang on to it, pass it down or sell it. It can
also be seen as similar to non-dividend paying equities. Eventually,
the only way these stocks bring value to you or your family is when
you sell them. However, farmland will bring returns to you and
generations of your family as long as they continue to own and
manage the land.
RENEWABLES AND THEIR IMPACT
Renewable fuels impact on the farm
Social and political concerns regarding climate change and fossil-fuel
dependency have led to a significant focus on renewable fuels, such
as ethanol, as a replacement for petroleum-based fuel sources.
Ethanol is primarily manufactured from crops such as corn, wheat
and sugar cane. According to the USDA, ethanol production in the
US increased from less than three billion gallons in 2003 to over six
billion gallons in 2007, and is estimated to exceed 12 billion gallons
by 2020. The Renewable Fuel Standard from the 2007 Energy
Independence and Security Act calls for total renewable fuel to reach
36 billion gallons by 2022.
Ethanol, no matter how viable or controversial, is mandated as a
renewable source of energy. At its most basic, ethanol is grain
alcohol, produced primarily from corn and sugar cane. The USDA
estimates that more than 40% of US corn production was used to
produce ethanol in 2011. In January 2011, the US Environmental
Protection Agency (EPA) approved the use of E15 gasoline for vehi236
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 237
FARMLAND AS AN INVESTMENT
cles manufactured in 2001 or thereafter. Almost all gasoline in the US
is E10, or 10% ethanol content. The increase to E15 will help the US in
its goal of using 36 billion gallons of renewable fuel by 2022, as per
the Energy Act of 2007.
In 2004, the US government passed a 45 cents-per-gallon tax
credit, commonly known as the “blender’s tax credit”, to provide an
economic incentive to blend ethanol with gasoline. The official name
is the “Volumetric Ethanol Excise Tax Credit”, and it was part of the
American Jobs Creation Act of 2004, although the incentive expired
at the end of 2011. In response, critics have argued that ethanol is an
inefficient source of energy and should no longer be supported by
the government. However, it seems unlikely that ethanol production
will disappear in the near future. The federal government does not
look to be changing these mandates.
Wind energy is another source of commodity revenue for the rural
landowner. By its very nature, farmland usually lies in the vast
expanses of open prairie that allows the wind’s unfettered flow.
Wind energy could even meet 20% of the US electricity demand by
2030. According to the US Department of Energy (DoE), farmland
owners can benefit from wind energy by having one or more wind
turbines placed on their property and receive a lease-rate payment
per turbine.
Landowners can receive up to US$15,000 annually per turbine,
although each wind company’s contract will differ. One wind
turbine only requires roughly a single acre of land and has minimal
effect on farming practices. One acre of cropland is lost, but is
replaced with revenue from wind turbine leases. Once the wind
turbines are finalised and constructed, landowners typically receive
fixed and variable payments based on electricity production. South
Dakota is in an excellent position to capitalise on wind energy, as the
state is known as the “Saudi Arabia of Wind.”
According to Dakota Wind Energy, South Dakota has the wind
potential to meet 50% of US electricity demand. It ranks fourth in the
nation in wind power, behind North Dakota, Texas and Kansas.
Since the late 1980s, the cost to produce wind electricity has dropped
a huge 90%, according to the American Wind Energy Association
(AWEA). Although wind energy costs are not as low as for conventional power, ever-improving technology is driving wind energy
costs down. The government has helped promote the development
237
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 238
COMMODITY INVESTING AND TRADING
of wind energy through subsidies, such as accelerated depreciation
and the production tax credit (PTC), which offsets the cost of development.
The primary constraint of wind energy is the transportation of
electricity. Since electricity must be used immediately or transported
to a power plant, wind turbines must be closely connected to electric
grids that can transmit the energy. The majority of the windy regions
of the US are located in rural areas with limited amounts of energy
demand and transmission capacity.
One solution is the Green Power Express transmission line being
developed by ITC Holdings Corporation. The transmission lines
would span roughly 3,000 miles from the Dakotas into Wisconsin,
Illinois and Indiana. The Green Power Express, due to be completed
by 2020, will provide a path for newly generated electricity to travel
to heavily populated areas such as Milwaukee and Chicago, and
even open up the entire eastern seaboard. This may very well
involve an opportunity for landowners to lease land for infrastructure development in support of the initiative.
Fuels based on crops may be new, but a windmill on a US farm is
as old as a Norman Rockwell painting. Farms started featuring
windmills on their properties as early as 1900 for the purpose of
powering the well pump. It was not electricity, but the mill generated power and reduced the need of human or animal power
through harnessing natural wind energy. Efficiently introducing the
new technologies of wind turbines and eco-fuels allows a landowner
to even further diversify the sources of revenue from their farming
enterprise.
Increases in demand for agricultural products
Grain supplies in the US and globally are at decade lows, driven by
emerging market demand, disappointing US yields and demand for
bio-fuels. The ending corn stocks-to-usage ratio has been trending
downwards, from roughly 20% in 2004 to 5.6% in 2012, according to
the USDA (these figures were calculated by the authors; the data on
which this is based can be found here: http://www.usda.gov/oce/
commodity/wasde/).
In the USDA’s October, 2012, update of “World Agricultural
Supply and Demand Estimates” report, ending stocks for 2012/13
are projected to be down by 37% to 619 million bushels, as corn use is

expected to exceed production by 444 million bushels and the
Midwestern US has had the worst drought in over 50 years. US corn
stocks have declined to a 21-day supply, meaning that if corn
production was halted, the US would run out of corn in a little over
half a month.
The global demands for food and rising commodities prices have
driven agriculture fundamentals upwards. The USDA estimates that
farm incomes have been steadily trending higher, increasing from
28% in 2010, 47% in 2011 and was recorded at 14% in July 2013, and
will continue to rise – allowing farmers to reinvest their dividends
back into farmland to expand their operations.
Despite the rapid growth in agriculture, farmers’ balance sheets
remain very conservative. Strong farm income and minimal use of

debt have allowed the US farm sector to maintain conservative
balance sheets as current debt-to-assets ratios continue at decadeslong lows. New banking regulations have restricted the access to
capital for farmland buyers, and loans secured by farmland are typically limited to 50% of the purchase/appraised price. This secure
financial situation bodes well for farmland (farmland owners tend to
be more on the commonsense side of economics).
PRODUCTION AND ITS LIMITATIONS
Limits to production
Farmland values are expected to continue their momentum into the
2020s and beyond due to the strong global and ever-increasing
demand for food. The world’s gross agricultural output must
increase by 3.4% to meet this demand, according to the FAO. The
two primary ways to increase agricultural production are to either
increase the amount of acres planted or increase productivity with
technology. With urban sprawl and land development, increasing
yield seems to be the logical answer.
The future ability to expand arable acres will be difficult. The
prime areas for farming have already been identified, are being used
for production and have built-in transportation and infrastructure
support. The marginal arable acres that can be put into production
will be in odd, out-of-the-way places with less than optimal growing
conditions and possible transportation issues. However, there is a
way to grow yield and increase arable acres.
Although the introduction of genetically modified organisms
(GMOs) has been somewhat controversial, they have not only
increased bushels per acre in standard farming regions, but they
have also brought better drought and cold tolerance in the US, as
well as expanding the land area that can be used for cold-sensitive
crops. For instance, the land planted to both corn and soybeans since
the late 1990s has extended into the colder north and drier west
areas. The acreage allotted to corn and soybean production is
expanding northwest to regions where the number of growing
degree days are less. Crop insurance for corn acreage now expands
60 miles further north into Canada. As a result, the Corn Belt and,
along with it the opportunity to invest in high-quality producing
farmland, continues to grow.
240
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 241
FARMLAND AS AN INVESTMENT
Acres in conservation programmes
There is yet one more resource for production: farmland set aside
under the Conservation Reserve Program (CRP) could be added to the
amount of US arable acreage. According to the USDA, 31.3 million
acres had been enrolled in the CRP under almost 738,000 contracts by
the end of 2010. As the CRP contracts expire, much of this land may be
put back into production, but a majority is marginable at best, which is
the primary reason it was put into the programme in the first place.
The CRP pays landowners not to farm their cropland in order to
protect areas where wildlife can grow and fertile land can take a break
from producing crops. Other environmental programmes include
environmental quality incentives and wetland preservation. This
must be done for the long-term health of the soil. CRP will provide
more acres in the US for production, but due to the lack of soil quality,
the effect on total production will be minimal.
GLOBAL FARMING
Farm growing in other global regions
The amount of acres of arable farmland has been almost static as the
non-farm development of farmland in North America and Europe
has been offset by expansion of farmland in Africa and South
America. There are approximately 1.5 billion hectares being farmed
around the world. The FAO estimates that the world has a total of 2.5
billion hectares of “very suitable” or “suitable” land for farming and
raising crops. About 80% of this reserve land is located in Africa and
South America. The investment bank Credit Suisse estimates that
there is only about 300,000 hectares of additional potential acreage,
with the majority in Brazil and Indonesia.
Table 9.2 summarises the acres in use in 2013 and potential global
arable acres. The primary expansion opportunity lies in Brazil,
where the government organisation Conab estimates there are an
additional 106 million hectares available for agricultural development. Historically, the soil was thought of as unfarmable due to high
acidity levels and lack of nutrients. However, technologies such as
strip tilling, soil surveys and Global Positioning Systems (GPS) have
allowed farmers to improve soil fertility, and a new type of soybean
developed to grow in tropical climates from the early 1980s meant
that farmers were able to start producing crops in previously unsuitable acreage.

Indonesia has a huge opportunity to expand acreage for palm oil
cultivation. The Indonesian government estimates that it is only
using half of its land available for cultivation. In January 2011,
Indonesia targeted expanding the county’s agricultural land by two
million hectares in the medium and long term, although this plan has
received a great deal of criticism as it would result in the removal of
tropical forests.
Ukraine, Russia and Kazakhstan saw a substantial decline in
arable acres and crop yields following the decline in communism
during the early 1990s. This demonstrates the loss of the motivationto-yield prospect of farming: farming is hard work and if your labour
goes into the pockets of organised crime or corrupt government,
there is no incentive towards healthy crop production. The FAO estimates that arable acres declined 11% between 1992 and 2005. Credit
Suisse estimates that if arable acres return to 1992 levels, that it
would add 1.9% to the total global arable acres.
Big (farm) trouble in China
There has been much speculation, and even fear, about the rise of
China. Chinese demand for agricultural products will likely be a key
force in these markets for the coming decades. The year 2010 marked
a new era for China as it announced it would no longer be selfsufficient in corn production. The demand of the most populated
country in the world for corn and feed is now outpacing supply as
the nation continues to consume more and more protein. China and
its people are in the process of transitioning from a grain-based diet
242
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 243
FARMLAND AS AN INVESTMENT
to a protein-based diet. On average, it takes seven pounds of grain to
produce just one pound of meat, according to the Earth Policy
Institute.
One of the primary problems limiting China’s ability to feed itself
is its land imbalance. China has roughly 20% of the world’s population with only 7% of the world’s arable land. The supply of arable
farmland in China is decreasing rapidly as well. By 1950, China had
lost a fifth of its arable land due to erosion, desertification and development, and is expected to lose 10–15 million more hectares by 2020,
according to the UN.
In order to be self-sufficient in grain production, the vice minister
of agriculture, Wei Chaoan, stated in 2010 that China needed to
maintain 120 million hectares for crop production until 2020.
Government figures estimate that the amount of arable land is actually 122 million hectares, which has remained unchanged since 2005.
Bank of America estimates that China’s arable land has already fallen
below the 120 million hectare threshold and could decrease to 117
million hectares by 2015.
As its economy and population grow, China will have to increasingly rely on the import market to solve their shortage of corn and
other foodstocks. Chinese imports of corn will grow from 1.0 million
tons in 2010 to 15 million tons in 2014–15, according to the US Grains
Council. 15 million tons of corn translates to Chinese imports of 600

million bushels, equal to 15 tons of corn, will have a substantial
impact on global corn stocks.
China’s transition to a net importer of corn is very similar to its
transition to becoming a net importer of soybeans. Before 1995,
China was a net exporter of soybeans, but by 2010 it was the world’s
largest soybean importer, importing more than 57 million tons of the
crop, 21.6% of world production, according to the USDA. The rapid
industrialisation of developing markets will have serious repercussions on the demand for grain. In China specifically, there may be
around 500 million more people demanding a protein-based diet.
China is not the only example of a developing country that has
an increasing appetite for grains. As the world’s middle class
continues to develop, the demand for grains will continue to grow
exponentially.
Global demand for farm crops and commodities
According to the US Census Bureau, there were approximately 7.0
billion people inhabiting the Earth in 2012, compared to just 1.7
billion in 1900 and 5.8 billion in 1985. The rate of population growth
is not expected to temper as the United Nations estimates the world’s
population is likely to reach 9.2 billion by 2050. Most of this population growth is expected to originate in emerging economies, with
developed countries remaining stable.
The global population growth rate is expected to decelerate due to
lower fertility rates, to roughly 1% by 2030, down from a 2% annual
growth rate in 1970, according to the United Nations. Despite the
slower population growth rate, life expectancies have substantially
improved from 30–40 years in pre-industrial times, to roughly 65
years. The prospect of feeding a demographic that is becoming less
productive is another factor that puts a strain on food production.
In order to feed the world’s growing population, agricultural
output will need to double by 2050, according to the FAO. This will
be a daunting goal to accomplish as agricultural resources are
already strained. Since the early 2000s, agricultural output has
grown by 2.4% annually. In order to double agricultural output by
2050, output must increase at 3.4% per year. To meet future demand,
experts are predicting that global agriculture will need to produce
more food in the next 50 years than what was produced during the
previous 10,000 years, putting more and more pressure on future
farmers and the land they use to produce our food.

Food demand is growing faster than population growth because
of the development of middle classes in emerging markets, due to
above-average GDP growth. The Brookings Institution estimates
that, by 2021, China’s middle class could grow to over 670 million,
compared to only 150 million in 2010. Economists have long shown
that, as GDP rises, so does the consumption of animal protein as a
percentage of diet. As emerging economies continue to develop,
there will be a transfer from a grain-based diet to a protein-based
diet. Over half the increase in global calorie consumption since the
early 2000s has been a result of increased meat consumption,
according to the FAO. It takes two pounds of grain to produce one
pound of chicken, five pounds of grain to produce one pound of
pork and seven pounds of grain to produce one pound of beef.
Again, this represents a great demand for commodity production.
SUMMARY
Farmland values have been steadily increasing due to increased
commodity production on farmland, but the primary driver of
future value increases will derive from the supply and demand of
the commodities grown from the land. Corn supplies are at their
lowest levels in decades. The major difference between the 1995 corn
supply and corn supply in 2013 is that global corn production was
low in the mid-1990s due to poor production, which was only a
short-term effect. That US corn supply has become an alarming 20
days is due to the increased usage of corn across the entire world.
What is exciting about farmland is that the agriculture proposition
245
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 246
COMMODITY INVESTING AND TRADING
is still the tip of the iceberg. Most agriculture investors are attracted
to the sector because of the wealth creation due to the transfer to a
protein-based diet in emerging markets. China is expected to
increase corn imports from 1 million tons in 2010 to 15 million tons
by 2014. The biggest demand for grain by the emerging markets has
not even occurred yet. The basic supply and demand is in place for
farmland to continue its bullish trends in the long term.
Although the amount of farmland is limited in the US, farmable
corn-producing land is expanding into areas with great soil but
heretofore slightly unsuitable climates in the Midwest, primarily due
to biotech seeds. Large seed and agrichemical companies have
focused years of research on higher performing varieties and hybrids
of important food and feed crops. The next generation of biotech
traits focus on greater productivity, improved nutrient use, disease
resistance, plant density and drought and cold tolerance.
While GMOs may bring a degree of controversy, they also
generate much-needed crop acreage and yield. And with people
always looking for safe places to invest, this can translate to a great
investment upside through increased commodity production.
Although farmers make up the majority, people from many
different walks of life own farmland, and outside investors have
always had a minority interest. However, outside investor interest
has grown latterly and will keep growing as farmland continues to
feed the world’s growing population. Almost 200 investment firms
are expected to invest US$30 billion in farmland by 2015, according
to Michael Kugelman of the Woodrow Wilson International Center
for Scholars. Worldwide media coverage now includes farmland on
a daily basis and the expansion of farmland as an asset class
continues to occur.
The average age of the US farmer is steadily increasing. The 2007
Census of Agriculture reported their average age had increased from
50.3 in 1978 to 57.1 in 2007. The ageing farmer may provide an opportunity for the non-farmer investor to get into this commodityproducing market. There was a time when the family farm went to
the son when the father retired or passed on. However, societal
trends have seen people selling the family farm and getting out of the
family business.
Demand is growing for farmland as the world’s population and
global needs for food increase. What many do not realise is that the
246
09 Chapter CIT_Commodity Investing and Trading 26/09/2013 09:59 Page 247
FARMLAND AS AN INVESTMENT
supply of farmland is not changing, thus creating a severe imbalance
in its supply and demand. An investment in farmland over the long
term will provide a steady stream of income and capital gains due to
the increasing global demand for agricultural commodities, driven
by the rising world population, rapid growth in emerging markets
and continued demand for ethanol and bio-fuels. Demand for agricultural commodities is outpacing supply, which positions farmland
for long-term appreciation.

Agriculture Trading
Patrick O’Hern
Sugar Creek Investment Management
The pool of participants trading in agriculture commodities has
grown rapidly in number and type since the beginning of the 21st
century, thus increasing diversification and liquidity across the agriculture sector. Increased participation has been witnessed across
each subset of traders, including the commercial, non-commercial
and index-trading communities. This growing diversification across
agriculture markets has raised the bar for money managers and
proprietary traders alike who are seeking to exploit positive risk–
reward opportunities. This chapter will provide descriptions of these
types of traders, their behaviour and objectives. This chapter is
arranged into three sections, which look at, respectively, the participants in the agriculture markets, trading in these markets and the
strategies utilised.
PARTICIPANTS IN AGRICULTURE MARKETS
Commercial traders
It is important to consider the commercial subset of traders, and
better understand their activities and objectives. Commercial traders
as defined by the US Commodity Futures Trading Commission
(CFTC) are those who use futures or option contracts in a given
commodity for hedging purposes. Commercial traders hold positions in both the underlying commodity and in the futures (or
options) contracts on that commodity. In agriculture, commercials
can be producers, merchants and end-users, all of which come to the
market to manage business, price and margin-related risks.
249
10 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:00 Page 250
COMMODITY INVESTING AND TRADING
Commercial trading activity has grown to become more sophisticated over time, as businesses have dedicated more capital to build
out trading desks by instituting structured commodity marketing
and risk-mitigating hedging plans for themselves and their
customers.
Figure 10.1 illustrates the growth in commercial participant
volumes traded across agriculture markets since the year 2000. The
expansion among the commercial trading community is viewed as
imperative as the globalisation of agriculture commodities has
increased the volatility in profit margins for all types of physical
commodity businesses. The increased volatility in profit margins has
driven commercials to put more emphasis on managing margin risk.
For instance, consider a large livestock feeding operation that takes
part in purchasing, feeding and selling the stock. The focus for this
operation is not only on hedging or marketing the sale price, but also
the purchase price and the input costs, including feed and energy
usage. Profit margins can vary greatly over the ownership period
due to changes in the price of input costs that can create enormous
business risks for the producer. For non-commercial traders, it has
become increasingly important to understand the behaviour and
underlying economics of these commercial trading entities, as the
business risk imbedded within participants such as the livestock
feeder are just as crucial as the supply and demand of the commodity
itself.
Figure 10.1 also illustrates the difference in the level of participation between commercial and non-commercial participants. This
difference highlights the importance for non-commercial participants to be more aware of the business and economic decisions being
made by commercial market participants, as they generally account
for 50–60% of the aggregate trading volume and total open interest
across agriculture markets. In commodities, open interest is the total
number of futures and/or options contracts in a contract month,
while total open interest accounts for the total amount of contracts
across the forward curve per commodity.
Generally speaking, the non-commercial participation ranges
around 40–60% of the commercial participation. As seen in Figure
10.2, CME Feeder Cattle non-commercial volumes are larger than
that of commercial volumes. This is due to an unusual amount of
commercial hedging activity falling into the non-reportable category,

thus being exempt from reporting. This occurs in all markets, but is
more pronounced in the livestock complex in general. The traditional commercials in live and feeder cattle are the feed yards, most
of which hedge their exposure in the live cattle. While cow/calf and
stocker operators utilise the feeder cattle market for hedging
purposes, the majority of their position sizes fall below the reporting
requirements.
Understanding the economics of physical commodity businesses
requires a strong knowledge of the individual components that
determine profit margins. This analysis of market fundamentals can
give traders an edge in generating opportunities and determining
the best types of trading strategy to implement. By understanding
the nuances of producer and merchant margins, non-commercial
traders can better assess buy-side and sell-side hedging activity that
takes place in the futures market. The most margin-sensitive hedgers
are active on both the buy- and sell-side; those include merchandisers, livestock feeders and processors. More traditional sell-side
hedgers include producers who have less market-related margin
risk, as their input costs are more tied to the operational overhead
and productivity. For instance, consider a grain farming operation:
in advance of each growing season, the producer must decide which
crop to plant by assessing a variety of important factors such as the
projected profitability per acre and the soil conditions across the
acreage in which the crop will be planted on. While the price of the
252
10 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:00 Page 253
AGRICULTURE TRADING
underlying cash commodity is a driver of the producer’s margins, it
is not the sole influence of what a producer ultimately decides to
plant. The producer has to account for factors such as soil condition
and potential yield variability based on crop rotation practices that
can have important implications on the level of production per acre.
Equally important to profitability are overhead and input costs such
as seed, machinery, financing, labour and fertiliser. These factors
create a fixed piece of the margin that producers must account for in
advance of planting their crop; as a result, the selling or marketing of
that crop is a vital decision.
For non-commercial traders, understanding the economics behind
the sell-side hedger’s decision-making can produce clear signals for
the future change in supply of a particular commodity. For example,
a noticeable lack of producer selling could indicate decreased
production for a commodity. In agriculture this could be due to a
poor growing season that has producers revising their expected
output, or it could be driven by the lack of economic incentive to
produce due to poor profit margins at the time of seeding.
Figure 10.3 highlights the growth in commercial trading across
individual markets. Note the growth in corn, sugar and soybeans, as
those commodities – aside from traditional uses such as feed and
food – have seen new demand come in the form of renewable energy
initiatives across the world. This relatively modern dynamic has had
both a direct and indirect impact across the agriculture market,
increasing participation by commercials and non-commercial
traders alike.
For example, the US Renewable Fuel Standard (RFS) requiring
gasoline refiners to blend corn ethanol was introduced in 2005. In
2007, the RFS mandate was increased to a 10% corn ethanol blend in
gasoline. The introduction and subsequent increase in the US renewable fuels mandate has resulted in increased demand and
competition for the US corn supply (see Figure 10.4). In 2011, around
40% of the domestic corn supply was consumed by the ethanol
industry. This additional demand has not only increased corn prices
but also that of competing row crops. As a result, the US RFS has had
a direct and meaningful impact on the US and global grain industry.
Consumers of grains have been affected as costs for feed and other
related inputs have increased in value. Markets such as livestock
have also been indirectly affected, as profit margins have at times

been negatively impacted by higher corn values resulting in
producers decreasing herd size or seeking alternative feed rations.
Another indirect affect of the US RFS has been on the soybean meal
market; during the ethanol production process, a third of the caloric
value of corn is retained in a by product called distillers’ dried grains
(DDGs). The introduction and prominence of DDGS have presented
another source of feed for livestock and poultry producers that have
altered pricing relationships between soybean meal, hay and other
sources of protein and roughage.
Non-commercial traders
This section covers non-commercial traders by providing descriptions of each type. This class of trading participant includes
fundamental discretionary and individuals trading proprietary
capital, to systematic and technical trading (all of which will be
detailed in this chapter). These traders can incorporate many
different forms of risk-taking based on return objectives, opportunities in their market and their approach to trading. Agriculture
markets present unique challenges and opportunities for noncommercial traders due to risks involving seasonality, liquidity and
weather.

to make trading decisions in the agriculture markets. Many of the
fundamental discretionary traders are registered with the US CFTC
as commodity trading advisors (CTAs), allowing them to market
themselves as an investment vehicle and manage client money in
individually separate managed accounts. There are also agriculture
specialist hedge funds that manage client money through onshore
and offshore vehicles. Since the beginning of the 21st century, the
agriculture markets have witnessed significant growth in the
number and size of assets under management and managers. The
increase in speculative trading across agriculture markets at the turn
of the century can be attributed to the evolution of electronic trading
as global speculators were increasingly allowed greater access, transparency and flexibility to execute trades on commodity exchanges.
Inflationary risks have latterly attracted speculators, as global central
bank’s stimulus and US Federal Reserve policy measures have
increased the flow of money in the marketplace. Fundamentally
speaking, agriculture markets have been attractive in regard to theories and scientific research surrounding climate change and its
possible implications for the future of global agriculture production.
Additionally, social economics involving population growth,
changing dietary habits and emerging market demand have all had
an impact.
These traders commonly come from physical commodity backgrounds – for example, having worked as a grain merchandiser for
Cargill or a sugar trader at Louis Dreyfus. Other traders that have
built out money management businesses have come from the agriculture trading pits of Chicago, where they were successful
proprietary traders or brokers for large commodity customers. In
most cases, the fundamental discretionary commodity trader has
spent an invaluable portion of their career working for commodity
businesses, where they learned the fundamental pillars of what
drives supply and demand for each commodity they trade. Figure
10.5 illustrates the percentage of non-commercial trading relative to
commercial trading across agriculture markets since 2000.
Proprietary traders: individuals and trading groups
Proprietary traders are a diverse subset on their own, as this type of
trader fills in all the cracks inside the non-commercial participant
spectrum. The most common “prop” trader makes a living trading

their own capital. Historically, many of these traders operated on the
commodity exchanges in the trading pits as “locals” (a pit trader who
trades for themself), assuming 100% of their own trading risks. Over
the years, the number of proprietary trading firms (groups of proprietary traders within one organisation) has grown due to the rise in
electronic trading and also because of the profitability in profit
sharing that owning a proprietary trading group can have. This business can be viewed as a private platform in which the owners of the
business hire talented individual traders, provide the overhead –
including back office, administrative, accounting and trading technology – for a share of any profits generated by the trader. Other
types of proprietary traders sometimes get unfairly described as less
knowledgeable or hot money. These are individuals who may not be
solely dependent on their success in trading commodities and at the
same time may not be aware of the significant risks that exist in
trading commodity futures. Both the type of trader and the amount
of capital traded is extremely diverse, from small accounts trading
under US$100k to multi-million dollar programs. This group of parttime speculators participates in the same market as professional
traders, and sometimes has very different views of the commodity
they are trading. They may be prone to participate in crowded
or popular trades. In agriculture markets, proprietary traders
and trading groups provide significant daily liquidity for other
participants.
Systematic and technical traders
Systematic and technical traders, much like the proprietary trading
segment, are a vital part of the anatomy of the agriculture futures
and options markets as their trading volume provides commercials
and money managers essential liquidity that allows them to use
structured, fundamentally based strategies. Increased trading
volume can narrow bid–offer price spreads, allowing all trading
participants a better trade execution. In the systematic world, there
are very few money managers that trade purely in agriculture; many
of the commodity systematic programs will allocate a risk bucket
toward the agriculture markets in the range of 5–40% of their capital.
This is largely due to targeted capacity of assets under management
for the trading program relative to the capacity in the agriculture
markets. Additionally, factors such as style, strategy and correlations
258
10 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:00 Page 259
AGRICULTURE TRADING
in respect to the systematic program models may dictate how much
the program allocates to agriculture markets. Pure discretionary
technical traders can be more opportunistic about their risk allocations across agriculture, which can provide outperformance relative
to other commodity sectors, resulting in an increased risk bucket.
Systematic programs trading in agriculture come in many
different forms, such as trend, multi-model, short-term momentum
and relative value. There has been considerable growth in systematic
programs which incorporate historical seasonality of prices and
spreads that have inherent fundamental ties. Some even will employ
econometric supply and demand modeling, which evaluate fundamental data produced for each commodity and then generates a
trading signal by way of a proprietary algorithm. This more sterile
and indirect fundamental trading from systematics can increase the
competitive advantage over discretionary participants due to the
discipline in generating and maintaining the trade. At other times,
this detachment can work against them as commodity fundamentals
can occasionally behave counter-seasonally and price patterns can
differ from historical norms – which can give the advantage to the
discretionary manager who has the ability to adapt to the changing
environment. Counter-seasonal price behaviour can occur due to
supply/demand shocks. In turn, these shocks can be driven by
issues such as supply chain logistics, global trade flow and currency
valuations. On the macro side of things, geo-political and economic
risks can alter price behaviour.
High levels of adaptability can also be a characteristic of a talented
chart technician who trades breakouts and mean-reversion strategies
across the market. The chart technician relies on price data, behaviour and chart formations to produce trading signals, and
participates in price discovery and provides liquidity to the market.
Often, the discretionary technical and fundamental participants who
are into the right side of a breakout do so more quickly. For the
fundamental discretionary trader, this can be due to their fundamental analysis, while for the discretionary technician this can be
reactionary as their technical indicators (non-fundamental statistics
derived from the markets price data) signal them to enter a trade. On
the other hand, multi-model and trend-based systematic programs
will often be into a breakout or changing price environment only
after a trend in price can be confirmed.

COMMODITY INVESTING AND TRADING
Commodity index and swap trading
A passive and increasingly common form of trade flows comes from
commodity index fund and swap trading participation. A
commodity index is an index that tracks a basket of commodities to
measure their performance. Commodity indexes are often traded on
exchanges, allowing investors to gain easier access to commodities
without having to enter the futures markets. The value of these
indexes fluctuates based on their underlying commodities, and this
value can be traded on an exchange in much the same way as stock
index futures. There is a wide range of indexes on the market, each of
them varying by their components. The Dow Jones-UBS Commodity
Index (DJUBSCI), which is traded on the Chicago Mercantile
Exchange (CME), comprises 22 different commodities ranging from
aluminium to wheat. Index funds also vary in the way they are
weighted; some indexes, for instance, are equally weighted while
others have a predetermined, fixed weighting scheme. For example,
the DJUBSCI is reweighted and rebalanced annually on a price–
percentage basis. While index fund trading flows are passive, they
have become more dynamic in their re-balancing and positioning
across the forward curves. Cleared commodity swap trading has
also become a larger piece of agriculture trading business by both
fundamental and speculative entities. A commodity swap is a
product whose exchanged cashflows are dependent on the price of
an underlying commodity. For commercial trading groups, a
commodity swap is usually used to hedge against the price of a
commodity. Therefore, in the case of a company that uses a lot of
corn, it might use a commodity swap to secure a maximum price for
oil. In return, the company receives payments based on the market
price. There are also cleared, over-the-counter (OTC) commodity
index swaps that allow investors to have direct exposure to a variety
of commodity or agriculture-specific indexes. Commodity index
swap contracts are based on indexes that are among those most
closely followed for investment performance in the commodity
markets. Investors, asset managers and financial institutions use
them to track performance or as benchmarks for their actively
managed accounts.

AGRICULTURE TRADING
TRADING IN AGRICULTURE MARKETS
Specialist traders in the agriculture sector use a wide range of nondirectional strategies, such as calendar/inter-commodity spreads,
and geographical and volatility focused arbitrage. The main drivers
of positive risk–reward opportunities from non-directional strategies
come from the identification of possible structural shifts in the shape
of the forward price curve or term structure, and the expected
volatilities in between the spot month and deferred futures contracts.
By identifying mispricing relative to forecasted expectations
between differentials in terms of price and/or volatility, specialist
traders can structure dynamic non-directional strategies across the
forward price curve. Time horizons traded across agriculture traditionally have ranged from 1–3 months up to 6–12 months in order to
provide sufficient time in which a strategy can reflect a trader’s
supply/demand forecast.
However, given increased volatility and short-term spikes in
correlation driven by outside market influences, some more traditional intermediate to long-term discretionary fundamental traders
have adapted by ratcheting down their trade durations in response
to increased downside risks coupled with higher rates of return on
underlying strategies over short periods of time. Latterly, outside
market influences combined with increased speculative interest
across agriculture markets made more accessible by electronic
trading have resulted in short periods of high correlation across
markets. Traders and larger investment funds that manage a diverse
set of exposures can now more easily increase and decrease risk
across all markets in a more efficient and timely manner. In the event
of sudden geo-political or macroeconomic risks, these participants
can now enter and exit trades in a more concentrated fashion –
causing cross-asset correlation to rise, typically only over short
periods of time (inside of one day to one week). At times where
prices skew non-fundamental due to a “risk on/risk off” environment, fundamental specialists are presented with the challenge of
appropriately managing risk while realising attractive trading
opportunities due to mispricing.
Market environments and volatility
The wider range in volatility across agriculture markets has
increased shorter-term trading by fundamental traders due to posi261
10 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:00 Page 262
COMMODITY INVESTING AND TRADING
tive risk–reward opportunities – ie, allowing traders to avoid tying
up margin dollars for long periods of time while still allowing them
to continue trading a long-term theme. There are risks which make
shorter-term strategies more challenging, predicated on the trader
being able to quickly filter possible risk–reward opportunities, all
while determining an appropriate size of risk allocation that is necessary to achieve their profit target. Psychologically, this style of
trading requires steady and consistent discipline due to the limited
timeframe available to place the trade. Therefore, timing is critical in
order to have success in short trading frames. For traders aiming to
trade in and out of deferred contract months, narrow time horizons
can particularly be a challenge as pockets of less liquidity and wide
bid–offer spreads can cause slippage and dilute trading returns. For
example, a short-term trade in the 4th option of Kansas City Wheat
may look good on paper, but dried up liquidity as a result of a
pending crop report could cause wide bid–offer spreads, making it
difficult to implement or exit the strategy. In summary, most of the
difficulties in short-term trading are created by timing, lack of discipline and varying degrees of liquidity.
Figures 10.6 and 10.7 illustrate the average true range (ATR) that is
a measure of volatility utilised by traders across the agriculture
space. Note the increased volatility in the ATR in both examples
shown.
Strategy selection
As volume and open interest vary across agriculture markets, so do
the type of suitable strategies and accompanying risks. Generally
speaking, total volumes and open interest in agriculture sub-sectors
rank in the following order, from largest to smallest: grain/oilseeds,
softs/tropicals and livestock/dairy. Given varying liquidity and
behaviour, traders must identify what strategies are best suited for
specific markets. This is especially the case for broadly diversified
commodity traders who may prefer taking a one-size-fits-all
approach to implementing and managing strategies across markets.
Specialist, individual market traders typically have a stronger handle
on risk tolerances and go-to strategies.
For example, relative value strategies in livestock that focus more
on pricing anomalies across the curve and less on absolute direction
work extremely well. While in the grains and oilseeds, more of a mix

AGRICULTURE TRADING
in options volatility, inter/intra commodity spreads along with flat
price strategies can offer better returns. Inter-spread is a crosscommodity spread, in this case inside the grains and oilseeds sector
(for example, selling wheat and buying corn). Intra-spreads involve
spreads across the same commodity forward curve. Grains and
oilseeds offer traders a wide array of choices in terms of strategy utilisation. The grains and oilseeds sector offer such a diverse and
attractive set of opportunities, such as inter-commodity relative
value – that is, a spread between two commodities. Due to strong
competition for global production acres and substitutability factors
across grains and oilseeds products, traders like to implement strategies that can exploit these fundamental relationships. Palm oil versus
canola oil or corn versus wheat are basic examples of global markets
that not only compete for production capacity, but for demand. The
fundamental competition inside the sector and the importance of
these markets globally is a strong reason why they offer relatively
deeper liquidity due to a more globally diverse set of participants.
Other sectors similar to livestock can be found in the tropical
commodity space, where sugar, coffee and cocoa specialists are
heavily reliant on managing relative value spreads and geographical
arbitrage. Table 10.1 outlines five types of trading strategies
commonly implemented across the agriculture commodities space.
Correlation benefit
Broadly diversified fundamental commodity traders have strong
incentives for including agriculture strategies in their portfolio, not
only because of stark fundamental differences and attractive themes
that exist across the sector. The diversity within the sector creates
significant de-correlation that does not always exist in other
commodity sectors, such as energy and metals. Correlations between
RBOB Gasoline, WTI Crude Oil, Brent Crude Oil or other energy
commodities can be high with each other, and they all tend to be
influenced by global macroeconomic headline risk and volatile stock
market fluctuations. Metals markets such as copper, aluminium, zinc
and palladium also show high correlations to each other. On the
other hand, across the agriculture markets one can find a number of
different combinations that offer low correlations – for example, live
cattle versus sugar and cocoa versus corn, which helps create natural
diversification.

correlation across sectors such as tropical and livestock commodities
(ie, cocoa versus live cattle).
Figure 10.8 shows the correlation benefits across various pairings
of agriculture commodities such as corn versus feeder cattle.
Investment flows, seasonality and weather
Low correlations across agriculture commodities are driven by
market-specific supply/demand cycles, adverse weather and
seasonality, which can create a rich set of diverse trading opportunities. It should be noted that, with increased volumes and
participants, more traders are leaning on strategies tied to a variety
of historical seasonality features, making it increasingly challenging
to generate positive alpha. This has been witnessed in intracommodity relative value, which is individual commodity spreads.
For example, flat price seasonality on spot month lean hog and live
cattle markets has pronounced impacts on spreads between the
nearby and deferred prices across their respective forward curves.
With access to 30-plus years of historical futures spread data, more
and more traders are implementing spreads based on these strong
seasonal tendencies, thus at times diluting the risk–reward profile
for spread trades relative to years passed. The popularity of seasonal
relative value trades has also increased mean reverting opportunities
for technical contrarians and fundamental specialists that are able to
identify if a spread has moved too far too fast.
The most successful traders are able to decipher the changing
influence of market participants, such as commercials, systematic
and swaps (as detailed in the first section of this chapter), and how
they impact seasonality and contribute to short- and long-term
cycles. For example, traditional or first-generation long-only swaps
managers are known to roll long positions from the fifth to the ninth
business day of the month; however, over time, the market response
to this practice by other speculative participants has caused swaps or
index funds to roll long positions earlier and later. In fact, index
funds have evolved their product suite, offering what are called
second- and third-generation products which adjust strategy for
curve contango or backwardation, attempting to capture alpha by
shifting their directional bets dynamically across the curve over optimised time horizons. In this case, the product suite is the index
products created in addition to the conventional style index, such as

the second- and third-generation products which incorporate
dynamic technical inputs such as open interest, volume and relative
performance across contract months to determine which contract
month to trade across the term structure. Traders who can filter and
understand the impact of important market factors such as weather,
demand and policy-related news (for example, changes in the regulatory environment) in an efficient manner will have a leg up on their
competition.
Figures 10.9 and 10.10 highlight the overall inconsistent correlations between individual agriculture commodities such as wheat
and corn relative to gold and crude oil. Note that times of high correlation – for example, 90-day rolling correlation between corn and
crude oil +50% – are often due to short-term periods of investment
flows driven by macroeconomic data and speculative re-balancing.
For discretionary agriculture traders, the main take away from
understanding index fund activity is that successful strategies must
withstand short-term periods of strong investment flows. Often,
price differentials across the forward curve of agriculture commodities can become skewed by such activity, by pushing prices out of
line with fundamental expectations. This type of price behaviour
caused by money flows often allows discretionary traders the opportunity to place complimentary spread strategies which are designed
to profit when the market corrects or reverts.
As previously mentioned, seasonal price behaviour can also
generate opportunities, as the underlying physical commodity
values react to productions cycles, weather events and seasonal
demand tendencies. These factors in normal environments have
created price activity that has produced consistent patterns over the
years (see Table 10.3 for more information about the planting of
grains and oilseeds). For example, corn and soybean volatility
seasonally strengthen during the US spring planting season and
peak during the growing season. In the lean hog market during the
late spring and early summer, increased demand for pork coupled
with a seasonal slowdown in production historically have supported
higher wholesale pork values and relatively higher lean hog futures
market prices in the summer contract months. Conversely, in the
autumn and winter, increased hog weights due to cooler temperatures and cheaper/higher-quality feed create some of the best feed
conversions per animal units of the year, typically resulting in large

beginning of the 2012 US summer growing season and near the end
of the US summer growing season. Note the beginning of the US
summer season was dry across much of the US Corn Belt but not in
drought (as illustrated in Figure 10.12), while by the end of the
summer most all of the US Corn Belt had fallen into severe drought
conditions.
Figure 10.14 shows the corresponding US crop conditions for corn
as the early season dryness evolved into a severe drought across the
US Corn Belt. Note the steep drop-off in conditions during the end of
June and throughout July 2012. Figure 10.15 illustrates the corresponding response in corn prices as conditions were continually
downgraded during the US summer growing season thus
decreasing production forecasts.
Fundamental data points
When assessing agriculture markets, traders will often structure
strategies around specific data points or fundamental reports that are
issued for each commodity. In the US, official government fundamental supply/demand information is produced by the US
Department of Agriculture (USDA). The USDA has many domestic
field offices and divisions, along with foreign agriculture attachés
stationed in the world’s key agriculture producing regions. These
divisions are tasked with compiling, accounting and analysing
important data involving such things as cash grain receipts, wholesale and retail meat prices, survey results regarding prospective
plantings and on-farm grain stocks. Every month, the USDA releases
a world agriculture supply demand estimate (WASDE) that
produces global and domestic balance-sheet estimates for important
agriculture commodities. This is just one of the many fundamental
reports produced by the USDA. While some traders may not necessarily trade off of supply and demand data – for example, growing

conditions in corn – it is important to be cognisant of the release dates
of fundamental reports, as price volatility can fluctuate sharply post
the release of such information. For traders, an equally important
endeavour, aside from analysing the report information, is to filter
which sentiment indicators or reports best compliment their strategy
and style. From a risk management standpoint, traders can judge
sentiment more qualitatively by using their discretion regarding
certain data and market response. For example, a trader will grade
surveyed analyst expectations against actual reported information,
as this type of methodology can provide them with a strong read on

market sentiment which can, in turn, help in the management of risk
after the release of a fundamental report.
Global macro commodity managers will utilise macroeconomic
indicators as an overlay to trading in agriculture commodities, both
for risk management and portfolio/strategy structuring. In doing so,
some traders will build proprietary models or take advantage of
experience and intuition when assessing price activity in macro
markets such as stocks, US dollar index and energy and currency
markets. Fundamentally, the USDA’s National Agriculture
Statistical Service and World Supply and Demand Forecasts produce
a wide range of agriculture research, surveys and periodic reports
for commodities such as corn, cotton, sugar and live cattle that
provide important information to the global market, offering guidance for future supply/demand expectations. For example, in the
grain and oilseed commodities the USDA reports information on
stocks, seeded acres and growing conditions. It is also important for
agriculture traders to understand which commodities are most
consumer-sensitive or can be most susceptible to macroeconomic
risks. Commodities such as live cattle (beef), cotton and orange juice
can quickly reflect changes in retail demand.
Aside from tracking underlying cash and retail values of those
commodities, traders will also assess economic data in order to gain
an understanding of consumer sentiment, such as US monthly
employment data and the Consumer Confidence Index (CCI). On a
less-frequent basis, country-specific policy changes regarding such
things as global trade and renewable energy initiatives can have a
277
10 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:00 Page 278
COMMODITY INVESTING AND TRADING
meaningful long-term impact on supply/demand and the global
trade of agriculture commodities. For example, in 2011 the US
entered into a bilateral free trade agreement with Colombia, which
came into effect in 2012. This comprehensive trade agreement eliminates tariffs and other barriers to US exports, expands trade between
the two countries and promotes economic growth for both. The
International Trade Commission (ITC) has estimated that the tariff
reductions in the agreement will expand exports of US goods by
more than US$1.1 billion, supporting thousands of additional US
jobs. The ITC also projected that the agreement will increase US GDP
by US$2.5 billion.
Many agricultural commodities also will benefit, as more than half
of US farm exports to Colombia will become duty-free immediately,
and virtually all the remaining tariffs will be eliminated within 15
years. Colombia will immediately eliminate duties on wheat, barley,
soybeans, soybean meal and flour, high-quality beef, bacon, almost
all fruit and vegetable products, wheat, peanuts, whey, cotton and
the vast majority of processed products. The agreement also
provides duty-free tariff rate quotas (TRQ) on standard beef, chicken
leg quarters, dairy products, corn, sorghum, animal feeds, rice and
soybean oil. This is an example of a trade policy between two nations
that will have a long-term impact on prices and the supply chain of
some commodities.
Technical inputs
From a technical chart trading standpoint, agriculture markets
provide a good platform to trade a range of styles, including
breakout, mean reverting and trend following. Technical indicators
such as Fibonacci retracements, relative strength index (RSI), market
profile and a variety of moving averages are utilised by traders.
Studying open interest and volume as well as viewing charts across
different time horizons – such as intra-day, daily, weekly and
monthly – help put medium- to long-term strategies into perspective.
For fundamental discretionary traders, technical indicators do not
necessarily have to generate trade ideas, but rather provide a confirmation for the entry or exit of a strategy. An example would be a
trader who has an underlying bearish directional bias in a market
based on demand concerns, and at the same time recognises that the
278
10 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:00 Page 279
AGRICULTURE TRADING
RSI indicator has fallen below the overbought level; just below this
price level, if the price weakness can be sustained, the price will be
able to drop below both the 20- and 100-day moving averages. This
confluence of signals can help confirm a potential entry point for the
bearish directional strategy. Using this methodology helps in adding
discipline, as it forces traders to adhere to the price action relative to
the technical signals, which can often indicate future longer-term
price movements before actual fundamental developments can be
realised. This is an important filter that can temper traders’ expectations behind their fundamental conviction about a commodity
market, and helps them to be patient in expressing strong convictions. Overall, there are a variety of technical indicators that can be
used in assessing the agriculture markets and, most importantly,
they offer a non-biased overlay to discretionary decision-making.
Figure 10.16 illustrates a combination of technical indicators that
can be used to signal a trading opportunity. Note, the moving
average cross as the 20-day crosses over the 100-day to the downside.
Additionally, in advance of this cross the RSI had been testing overbought territory, which indicates that the market maybe reaching a
top. In the case of this illustration, this was true and the moving
average cross provided a confirmation and a sell signal. Figure 10.17
illustrates a combination of Fibonacci retracement and moving
average cross that can be used to signal a trading opportunity and
provide the trader with a back drop in which to balance expectations.
STRATEGIES AT PLAY IN THE AGRICULTURE MARKETS
The previous section provided a general description of the types,
behaviour and objectives of traders in the agriculture markets. This
section will categorise the specific types of strategies being employed
by those participants, along with their risks and management of such
strategies. There are five main strategy types covered: directional,
calendar spreads, geographical arbitrage, crush spreads and options
volatility. Methodologies used in trading strategies involve the
research and analysis of seasonality, forward curve structure and
fundamental factors. Using those factors, traders are then tasked
with choosing the most suitable strategy that aligns with their fundamental thesis or return objective.

COMMODITY INVESTING AND TRADING
Directional
Directional trading strategies are a very common style of trade
employed by both commercial and non-commercial trading participants. Commercial traders using this strategy will utilise flat price
trades to market or hedge production or commodity risk. In its
simplest form, this can be implemented as a flat price futures buy or
sell or as a hedge against an underlying physical commodity exposure. For non-commercial traders, the flat price exposure is a source
of beta that compliments their speculative ideas on future price
direction. Flat price trades among the non-commercial and commercial trading community can be expressed in many different forms.
Different style of directional bets include options spreads, risk reversals such as owning a call and selling a put against the same
underlying contract month, and synthetic options that involve
trading futures and options in the same contract month.
Prior to entering a directional trade, traders must evaluate a
variety of risk–reward factors such as selecting the appropriate
contract month across the forward curve and choosing the expected
time horizons for the trade, while also establishing risk allocation,
profit targets and stop/loss level(s). Experienced traders looking to
place a directional bet in an agriculture market are always aware of
the calendar as seasonality plays a large role in the risk profile of a
directional trade. After taking into account seasonal factors, the
trader will determine which contract month can best express their
ideas on fundamental price movements. Since many commodities
futures in the agriculture sector span multiple crop years, traders
have to make sure their fundamental thesis ties to the appropriate
time horizon in which they are trading.
For example, during the month of May, an oilseed trader becomes
bearish and decides to sell the US soybean market on expectations
for an above-average new crop production, but sells the old crop July
contract in order to express their bearishness; while being short is the
correct directional position, in this case it is not the correct contract
month or season to be short based on the fundamental thesis. This
trader is taking significant risk by holding a short position in an old
crop contract that may be trading off of different supply and demand
fundamentals. Additionally, the risk–reward expectation for such a
trade could greatly underperform due to muted trade duration as
the July contract will have expired before new crop production is
282
10 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:00 Page 283
AGRICULTURE TRADING
harvested, therefore never allowing the market to fully price in the
trader’s fundamental price forecast. See Table 10.3, as the global crop
timetable shows traditional planting and harvest time periods for
corn, soybeans and wheat produced around the world.
After determining the best point to be positioned, traders must
decide how much risk or what level of conviction they have in the
trade. This determination comes from a confluence of factors
involving the price forecast, market volatility and expectations for
trade duration. If a trader has strong confidence in their fundamental
thesis and long-term price forecast, but the market volatility is high
due to shorter-term factors, they may take a “scale in” approach to
their directional position. Scaling into a strategy is a methodology in
which a trader increases risk by adding positions to the existing
strategy. This allows them to ultimately reach a high conviction or
risk allocation, while withstanding near-term volatility pressures.
Regardless of the conservative approach, traders still need to determine levels in which they will stop out of the directional position and
go to the sidelines. While liquidity in executing directional trades is
often better than liquidity available for more complex relative value
strategies, the returns on an unhedged directional trade can often be
more volatile, which makes risk management and position sizing
important.
Figure 10.18 offers an example of this type of risk differential,
showing the difference in ATR between an old/new crop corn
spread versus the individual components of the spread. Note the
ATR of the individual components, in this case July 2012 and
December 2012 corn traded as much as two or three times more on a
daily basis than that of the July–December 2012 calendar spread.
Additionally, note the convergence and divergence of the spread
relative to the individual components, as the tug of war between old
and new crop supply/demand played out over time.
Calendar spreads
Calendar spread strategies have grown in popularity among the
speculative trading community due to their embedded alpha generation and strong relationship with fundamental price relationships.
As defined in Table 10.3, a calendar spread trade is a strategy in
which a buy and sell are simultaneously placed across the same
commodity futures curve. Calendar spreads provide fundamental

traders with a non-directional bias and the opportunity to trade relative fundamentals across the term structure of a commodity.
Non-directional reasons to trade calendar spreads can involve price
relationships regarding cash basis and seasonality.
From a directional standpoint, some traders may entertain trading
a calendar spread as a hedge against being directionally positioned
at different points on the futures curve or as a more conservative bet
on directional price expectations against one leg of the spread. There
are many possible fundamental and technical drivers for trading
calendar spreads. Some of the most compelling calendar spread
strategies can be seen in Table 10.4.
Geographical spread arbitrage
Geographical arbitrage is another form of inter-commodity spread in
which a trader buys and sells the same type of commodity produced
across different regions of the world. These commodity futures
contracts often exist on different exchanges and have different
quality or grade characteristics. An example of trading a geographical spread would be purchasing Arabica coffee and selling Robusta
coffee. Trading a geographical arbitrage strategy is mainly carried
out by fundamental specialists due to the high level of specific
knowledge needed to understand the pricing relationships. For technical traders, this type of commodity spread can have appeal from a
mean reverting standpoint, as the trader will seek opportunities
when the spread between the two related commodities reaches
extreme levels. Purely trading geographical arbitrage from a technical standpoint, however, does come with significant risk as the flat
price direction of an individual leg of the spread can move oppositely for sustained periods of time based on specific
micro-fundamental factors. Other inter-commodity spreads can
have strong quality-based and seasonal aspects, such as trading
lower-grade US soft red winter wheat versus higher-grade hard red
spring wheat.
See Table 10.5, which details fundamental drivers for trading
inter-commodity or geographical arbitrage. The same technical
drivers can apply for these types of spreads as that outlined for
calendar spreads.
Figure 10.19 shows how the soybean to corn ratio provides an
example of blending technical, seasonals and fundamentals while

trader to deduce what fundamental drivers will result in the future

A crush spread is a form of arbitrage predominately used by
commercial traders in order to manage production-related margin
risk. Typically, a crush spread includes two or three individual
components. Speculative participants with a keen understanding of
production margins often like to implement crush or reverse crush
spreads as a proxy as it allows them to participate synthetically in

crush trade.
Options volatility
Trading of options volatility strategies offers traders with a wide
range of dynamic opportunities on a standalone basis, and also when
coupled with futures directional and relative value spreads. Trading
opportunities in options include individual commodity spreads and
direction or across commodities in the form of arbitrage.
Experienced relative value option specialists in agriculture are
frequently able to find attractive opportunities by trading differentials in volatility on an inter/intra commodity basis. Additional
strategies involve trading put versus call skews across one or more
contract months in one or multiple commodities.
Directional trading is also prominent in options by way of owning
net, absolute gamma or premium in any contract month. An example
of a net gamma options play would be to own a bull call spread in
which the trader purchases an at-the-money call and sells an out-ofthe money call against it at a slightly lesser value, resulting in a net
payment of premium and a net long volatility position. The number
of options strategies which can be expressed across agriculture
markets is seemingly endless, and they provide traders with unique
and niche opportunities to generate profitable returns. Table 10.7
details the three different types of options strategies that are often
traded across the agriculture space.
CONCLUSION
The speed of information flow and the sudden correlations across
markets from time to time can in some ways be attributed to the
success and growth of electronic trading, as a more diverse set of
speculative participants from around the world have virtual around
the clock access to trade and manage risk in most commodity
markets. In general, this new normal in price behaviour and
volatility offers more opportunities for multi-strategy and relative
value driven traders. Periods of high volatility and relatively wider
price ranges can frequently distort prices relative to perceived fundamentals, which can create unique opportunities. These types of price
environments are often associated with adverse market conditions;

Quantitative Approaches to Capturing
Commodity Risk Premiums
Mark Hooker and Paul Lucek
State Street Global Advisors and SSARIS Advisors
Many institutional investors now allocate to commodities alongside
the traditional asset classes of equities and fixed income, based on
the primary motivations of diversification and protection against the
risk of inflation. While commodities have indeed been less correlated
to equities and many other risky assets (and offered comparable
risk–return trade-offs, see Gorton and Rouwenhorst, 2008), in this
chapter we will show that those diversification benefits may be
enhanced through a deeper understanding of how and why different
passive and active strategies tend to perform in different market
environments. Our conceptual frame of reference views most investment strategies as either convergent or divergent – performing well
in either “normal” or more dislocated periods – and is applicable at
any level of aggregation, from individual securities to sectors and
markets as well as combinations of asset classes.
We will begin with a brief review of commodity benchmarks,
highlighting the degree to which they are considerably less passive
than traditional equity and fixed income benchmarks, as well as an
overview of active approaches to commodity investing. We will then
present a detailed discussion of the convergent/divergent paradigm,
and demonstrate with an example how it can be applied within an
active commodities strategy, underscoring its effectiveness during
the most recent global financial crisis when traditional approaches to
diversification largely failed.

COMMODITY INVESTING AND TRADING
REVIEW OF COMMODITY BENCHMARKS AND OVERVIEW OF
ACTIVE APPROACHES TO COMMODITY INVESTING
Commodity benchmarks differ from their stock and bond counterparts in two main ways. First, there is no straightforward analogue to
market capitalisation for determining component weights – eg, the
index weight of crude oil relative to that of soymeal. Instead, various
commodity indexes, including the prominent DJ-UBS and GSCI
indexes, use factors such as trading volumes of the futures contracts
and worldwide production statistics to derive individual component
weights. The collection of production and trading volume data is
also subject to a series of decisions regarding sources, timing, data
revisions and additional factors. Commodity benchmarks are therefore subject to a much greater degree of subjectivity in determining
benchmark weights. Second, since commodity futures contracts
have a limited time before their expiration, a set of rules must be
constructed to determine when contracts are rolled from the near
month to a later-dated month. These rules must indicate whether
adjacent contract months are used, or if certain months are skipped.
In order to minimise the impact of the change over from one contract
to the next, the roll usually occurs over a period of several days,
which also must be specified within the rules. In this sense, passive
commodity investing should be considered semi-active.
Active commodities strategies
The broad universe of commodity futures contracts exhibits a very
low average correlation of its components, a wide dispersion of individual commodity futures returns, high volatility and large
drawdowns. For example, pairwise correlations between industry
group returns in the MSCI World Equity Index average about 0.5,
while analogous correlations between the constituents of the DJ-UBS
commodity index are closer to 0.2, and volatilities average about 50%
greater for commodities, at 30% versus 20% for equities.1 This
volatility and dispersion provides considerable opportunity for
skilled active managers to implement strategies that can provide
alpha over commodity index beta, while using risk controls to
reduce volatility and preserve capital. The combination of these
opportunities for active managers, in conjunction with the semiactive nature of the commodity index providers, makes a strong case
for active commodity management within an institutional portfolio.
296
11 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:01 Page 297
QUANTITATIVE APPROACHES TO CAPTURING COMMODITY RISK PREMIUMS
Strategies for active commodity management generally fall within
two categories: discretionary and systematic. In this chapter, we will
focus on systematic strategies, which are quantitative in nature,
using historical data to develop models that drive trading decisions
directly from feeding live data through the models. Quantitative
trading strategies are of course sensitive to the performance of their
underlying models, which typically have positive periods where
they perform as designed, and negative periods where factors
external to those included within the model drive more of the market
movements. For this reason, diversification of differently designed
trading models and approaches can greatly enhance the overall efficiency of a quantitatively managed portfolio of commodity futures.
CONVERGENT AND DIVERGENT STRATEGIES
The convergent/divergent paradigm was introduced in Chung,
Rosenberg and Tomeo (2004). It focuses on distribution of monthly
returns, their statistical properties and the cross-correlations
between those returns and aspects of the market environment.
Convergent return streams have monthly return distributions
represented by the shaded curve in Figure 11.1, and are generally
derived from fundamental or value-based methodologies. In a
convergent strategy, a manager often calculates an intrinsic or “fair”
value for an asset: a target price. If the asset is trading below the
intrinsic target price, the manager would seek to buy the undervalued asset. Conversely, if the asset is trading above the intrinsic
target price, the manager would seek to sell the overvalued asset.
The goal of the traded position would be for the current asset price to
converge to the target price and generate a positive return. The
manager seeks over- or undervalued assets with the expectation that
these assets will move toward their fair values, allowing them to
exploit the temporary mispricing. Convergent strategies tend to be
based upon fundamental methodologies, although certain quantitative methods – for example, mean reversion strategies – also tend to
produce convergent return streams.
Most passive investments – indexes – are also convergent in their
nature. Passive index investing has the goal of capturing the risk
premium of the asset class. Fixed income risk premiums come from
credit and duration risks. The equity risk premium is associated with
earnings growth. Commodity risk premiums are derived from the

inventory levels of the underlying commodities (Gorton, Hayashi
and Rouwenhorst, 2006). A passive investor in these indexes is
looking for the index return to converge to the expected risk
premium. Furthermore, as emphasised in Ilmanen (2011), asset class
risk premiums tend to be larger for investments that perform
poorly during crisis periods (“bad times”) so that they have some
characteristics of selling insurance. Assets that produce positive
returns in normal periods and suffer large losses in crisis periods are
convergent.
Convergent investments normally exhibit fairly consistent return
streams with a high frequency of small positive returns. Their consistency and low volatility can give them high Sharpe ratios and make
these types of strategies very attractive to investors. One of the weaknesses that convergent strategies exhibit is their negative skewness.
As shown in Figure 11.1, the convergent return distribution has a
significant left-hand fat tail. After a series of several monthly returns
clumped around zero with a positive mean, market events can occur
where convergent strategies experience significantly (2–3 standard
deviation or more) negative returns. These events tend to be termed
“crisis events”, such as the 1987 stock market crash, the 1997/98
Asian currency/Russian debt/LTCM crises, the 2007–08 global
298

QUANTITATIVE APPROACHES TO CAPTURING COMMODITY RISK PREMIUMS
financial crisis (GFC) and the 2011 European debt crisis. During these
crisis events, fundamental and value-based strategies often have
significantly negative performance. When behavioural finance
concepts such as “fear” and “greed” drive market movements, asset
prices succumb to panic and overshoot their fair values. Convergent
approaches have great difficulty in this type of crisis environment
because, as an asset price drops due to panic and fear, the convergent
model suggests that the asset is an even more attractive buy. The
model will eventually be correct when the asset price hits a bottom
and the crisis passes, but trading positions taken along the way may
experience heavy losses. Unrealised losses in commodity futures
contracts force future commission merchants (FCMs) to issue margin
calls. If further capital is not produced, the manager’s positions are
liquidated and the losses are realised. This situation was aptly
described by a quote attributed to John Maynard Keynes: “Markets
can remain irrational longer than you can remain solvent.”
A prime example of crisis price dynamics is illustrated in Figure
11.2: the price of the December 2008 Nymex crude oil futures
contract. Within a span of 10 months, the contract rose from
US$84.62 per barrel to US$146.68, before sinking to US$49.62.
Somewhere within the range of a 73% run-up and a 66% decline was
an intrinsic value for crude oil, but the price had been driven far
beyond fair value in both directions.
During market dislocations, such large directional moves are
common. The most striking characteristic of these crisis events is an
increase in market volatility (almost, by definition, a crisis event
includes an increase in market volatility). A secondary effect is an
increase in magnitudes of correlations. Assets that previously exhibited low correlations tend to become correlated during a crisis. A
tertiary effect is the increase in serial price correlation or autocorrelation within individual markets. Table 11.1 shows these three effects
during the 2007–08 GFC: over 2007, the DJ-UBS index had an annualised volatility of 12%, average correlation of its components of 0.15
and near-zero autocorrelation of those components’ returns. During
2008, each of those statistics more than doubled, with serial correlation rising more than five-fold. When markets become driven
beyond fair value and fundamental convergent methodologies fail, it
is the divergent category of strategies that can capitalise on the
increase in market autocorrelation.

Divergent strategies capitalise on directional market moves. These
strategies, which include momentum and other trend-following
approaches, seek to take positions based upon the analysis of historical price data and the direction the market is currently moving. They
tend to perform well as the rate of change in volatility levels
increases, which is also when markets tend to exhibit more
pronounced degrees of autocorrelation.
While in normal or rational market environments convergent and
divergent strategies are usually uncorrelated, during crisis events
and irrational market environments the two become negatively
correlated. Divergent strategies perform well and experience righthand tail events at the same time that convergent strategies have
their negative left-hand tail events. When markets exhibit strong
directional moves such as with crude oil in 2008, momentum/trend
strategies can capitalise on the shifts away from fair value. Divergent
strategies in this sense are directly opposite to convergent strategies.
As crude oil rose in 2008 and became more and more expensive,

convergent models saw the asset as overpriced. Divergent models
saw the increasing price as a trend and favoured the asset. Divergent
strategies require a significant retracement in market price before
they will change their assessment of a market trend. Similarly,
during the market decline in the second half of 2008, as crude oil
became less and less expensive, convergent models favoured the
asset, while the strong downward move forced divergent trend
models to sell the asset.
The contrasting styles of convergent and divergent strategies and
the diversification of their respective return stream distributions
leads to the benefit of allocating to both strategies. Commodity
markets facilitate this diversification, because with the wide dispersion and low average correlation within the commodity universe,
divergent events can occur in one commodity sector while other
sectors exhibit a largely convergent environment. For example, in
2012 significant bullish moves in agricultural markets took place due
to the drought conditions in the US, with corn up more than 60% and
soybeans, meal and oil up roughly 25% between mid-June and early
August. These markets exhibited strong directional trends that
divergent strategies were able to capture, while other market sectors
provided strong performance from convergent strategies.
Investment strategies that allocate to successful convergent and
divergent techniques will outperform those that allocate to only one
or the other on a risk-adjusted basis.
A CONVERGENT/DIVERGENT ACTIVE COMMODITIES EXAMPLE
In order to demonstrate the beneficial effect of a convergent/divergent quantitative approach to commodity investing, we present here
examples of the two trading methodologies, their individual performance relative to a passive benchmark index and the increased
301
11 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:01 Page 302
COMMODITY INVESTING AND TRADING
efficiency achieved by their combination. The sample period for this
analysis is January 1996 to October 2012.
A simple divergent momentum strategy described by Spurgin
(1999) uses three lookback timeframes in order to determine long or
short positions in each market traded. The three timeframes – 15, 27
and 55 days – were selected to best replicate an index of commodity
trading advisor (CTA) managers trading a broad range of futures
contracts. The signal derived from the momentum strategy is generated by comparing the price at time t with the price at a fixed number
of days ago. For example, in the 15-day system, if Pt > Pt-15, the
market trend is considered to be positive and a long position is taken.
If Pt<Pt-15, the market direction is considered to be negative and a
short position is taken. If the prices are the same, no market direction
is indicated and no position is taken. Trading signals from the three
lookback timeframes are averaged. In this chapter, we modify the
momentum trading methodology by not taking any net short positions. If an aggregate signal is negative, indicating a short, a flat
position is taken instead. This modification has the effect of making
the momentum system track the index more closely, since the index
itself does not take short positions. Signals for each of the 20 components of the DJ-UBS index are generated on a daily basis. Profits and
losses were calculated by equally weighting the system’s return
streams on each of the 20 components and rebalancing on a monthly
basis. The DJ-UBS index is presented as a benchmark for comparison
in Table 11.2. The momentum strategy outperforms the DJ-UBS
index while exhibiting less than half of its volatility.
For convergent strategies, we investigate two quantitative
approaches. The first relates to the Gorton–Hayashi–Rouwenhorst
view that inventories are the key fundamental for commodity
futures returns, and that the degree of contango or backwardation in
the futures curve reflects those fundamentals. Here, we construct an
alpha signal for each commodity each month. That alpha is a simple
function of the relationship between the second-from-expiration
futures price and the next-to-expiration contract price.
The second convergent approach models each commodity’s
returns using a Markov switching model. Here, each commodity’s
monthly return is assumed to be drawn from one of three different
normal distributions, called regimes, each with its own mean and
variance. The process moves from one distribution to another (a

* The combined convergent/divergent strategy is rebalanced monthly

to a set of Markov transition probabilities. Expected returns are
computed each month for each commodity by multiplying the estimated probabilities of being in each regime by their respective means.
Those means, variances and transition probabilities are estimated
periodically through time and evolve as new data accumulates.
The alpha estimates from these two convergent approaches are
averaged, and then run through a mean-variance optimisation to
produce over- and under-weights relative to the DJ-UBS Commodity
Index benchmark weights that also satisfy various constraints, such
as limits on short positions and on active exposures to individual
commodities and commodity groups. The return stream produced is
summarised in the final column of Table 11.2. The convergent
strategy also outperformed the DJ-UBS index, but with about a third
greater volatility, for a return-to-risk ratio somewhere in between the
index and the divergent strategy.
As mentioned above, convergent strategies tend to perform well
when assets move toward intrinsic or fair valuations, which tends to
be when markets are in more normal regimes or recovering toward
normality after severe shocks. By contrast, divergent strategies tend
to perform well during crises when markets are driven beyond fair
values. Consistent with this logic, the convergent backwardation–
Markov switching strategy had average excess returns that were
slightly negative in 2008 as markets reacted severely to the global
financial crisis, but outperformed by more than 17 percentage points
303
11 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:01 Page 304
COMMODITY INVESTING AND TRADING
in 2009 as markets dramatically recovered. In contrast, the divergent
momentum strategy outperformed the index by more than 45% in
2008, and underperformed by more than 12% in 2009.
The most striking aspect of the convergent and divergent excess
return streams is how their correlation varies across time. The overall
correlation is slightly negative, at –0.16. However, during the crisis
and recovery period of 2008–09, it rose dramatically (in absolute
terms) to –0.51, demonstrating the very powerful benefit through the
diversification achieved by combining these two return streams. A
programme allocating one half of the portfolio to each strategy and
rebalanced on a monthly basis showed an 8.3% annualised rate of
return with a 13% annualised standard deviation (outperforming the
benchmark index by more than 3%, with volatility reduced by more
than 3%) in a backtest over the test period of January 1996–October
2012.
CONCLUSION
Most approaches to diversification focus on average correlations
over periods of time that encompass full market cycles – indeed, that
is often by design, implicitly assuming that fluctuations in correlations through time are primarily noise and so should be averaged
out. That approach has disappointed investors during crises as
realised correlations, particularly within the dominant convergent
set, “all go toward one”. The convergent/divergent paradigm, by
contrast, views variations in correlations – particularly as a function
of market stress and stability – as fundamental attributes of a
strategy that should be incorporated into portfolio design.
The example in this chapter showed that combining convergent
and divergent active quantitative strategies can provide significant
alpha over a passive index and stabilise the overall return stream of
the portfolio, especially during crisis event periods. In practice, we
have seen this concept can apply to fundamental active strategies,
passive strategies, other asset classes and the overall portfolio level
as well, where it may help overcome the challenge that diversification has often worked least well when it has been needed most.

this level of aggregation makes them reasonably comparable. Correlations and volatilities
are computed using monthly returns from 1999 to 2009.

Investors can get exposure to market-neutral returns in commodities
– commodity alpha – in many different ways. Active management is,
of course, one means of obtaining exposure to commodity alpha.
However, as commodities have grown as an asset class, a large
number of rules-based strategies (examples of which will be
provided throughout the chapter) designed to generate marketneutral returns have emerged. These systematic commodity alpha
strategies exploit structural characteristics of commodity markets,
and will be referred to here as “structural commodity alpha strategies”. They are not a source of risk-free returns. Their returns are the
reward for taking on risks that other market participants are
unwilling to take on a systematic basis.
The main goal of this chapter is to outline the major investment
themes among these structural commodity alpha strategies and
suggest a simple methodology for combining them into an absolute
return portfolio. After briefly introducing the three major investment
themes in commodities alpha, this chapter will examine each in turn.
First, it will cover curve placement strategies, discussing their rationale and relationship to storage economics. This section will also
explore how curve placement strategies are generally constructed
and their risks, as well as issues including seasonality and market
segmentation. The next section looks at momentum strategies, going
over the principle behind such strategies and their relationship with
the economic cycle. The section discussed the construction of
momentum strategies using price as a signal, and also using the

shape of the forward curve as a signal. It also assesses the distinction
between absolute and relative momentum.
The third section covers volatility strategies, examining the rationale of such strategies and comparing different implementations
using variance swaps and variance swap calendars and the risk–
return profile expected of each implementation. The final main
section discusses how to combine different alpha strategies into a
basket in order to achieve particular risk–return goals for the overall
portfolio. In the process, it also explores how the approach of
choosing a set of relatively simple, uncorrelated strategies is a means
to mitigate backtesting bias relative to out-of-sample performance.
Finally, we conclude by highlighting the main points considered
throughout the chapter.
In general, there are three major investment themes on structural
commodity alpha: curve placement, momentum and volatility.
Strategies that provide price insurance and liquidity to market
participants on a systematic basis are rewarded with positive
returns. These strategies are not riskless, but can be constructed to be
more or less independent of the factors that affect commodity price.
As a result, their returns have low correlation with market returns.
Even although these strategies are not independent of market fundamentals, they cannot be replicated by simply getting exposure to a
broad-based commodity market benchmark. Hence, they constitute
pure commodity alpha.
Curve placement strategies are one of the most basic and popular
ways to generate commodity alpha. In essence, they exploit market
segmentation (ie, the fact that different market participants have
different hedging needs) across different commodity forward
curves, as consumers, producers and index trackers tend to use
different contracts for their hedging needs. Curve placement strategies aim to generate returns by taking advantage of the differences in
hedging needs between producers, consumers and index trackers. In
addition, curve placement strategies are rewarded for providing
liquidity to market participants in less liquid parts of the forward
curve.
Momentum strategies can be used by commodity investors as a
source of alpha in many different ways. Momentum alpha is the
308
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 309
STRUCTURAL ALPHA STRATEGIES
reward for taking price risk from market participants ahead of the
market using the fact that commodity prices and inventories follow
persistent fundamental economic trends. In particular, roll returns
are closely linked to inventory cycles. Given that changes in inventories are the differences between supply and demand, momentum in
commodities is ultimately the result of persistence in inventory
levels and changes. As inventories build (or draw) slowly over time,
momentum generates alpha by identifying the commodity markets
that need to create incentives for market participants to balance
markets by moving physical commodities in and out of storage, or
incentivising changes in demand or supply.
Volatility strategies provide insurance to market participants and are
rewarded for taking price risk from market participants that are
unwilling to bear those risks. As in any other derivatives market,
implied volatility in commodity markets serves as the key parameter
for market participants – eg, producers, consumers, processors and
investors – to match supply and demand for options. However, there
is often a structural imbalance between buyers and sellers of options
in commodity markets. Market participants’ hedging needs cause
biases in the options markets, offering a source of market-neutral
alpha for investors.
CURVE PLACEMENT STRATEGIES
To understand how alpha can be generated by curve placement
strategies, we need to understand how commodity forward curves
are shaped and how different market participants segment themselves across the curves. Moreover, we need to be aware of when and
how these market participants position themselves throughout the
year and the trading flows associated with these positions.
Forward curves and the market value of storage
Commodity forward curves embed not just expectations about
future prices, but also the net costs of carrying physical commodities
over time. Hence, storage and financing costs largely explain the
shape of the curve in most commodity markets. A simple arbitrage
argument shows how the cost of physical storage should be equal to
the difference between forward and spot prices (see Figure 12.1). If
the net cost of physically storing a commodity is higher (lower) than
309

the difference between spot and forward prices, owners of the physical commodity would rather sell (buy) the commodity on the spot
market and buy (sell) it forward than store it. This dynamic would
force spot prices down and forward prices up when the forward
curve is not steep enough to compensate for storage costs. Similarly,
it would force spot prices up and forward prices down if the forward
curve is too steep.
However, storage costs interact with market expectations and the
need of physical players to own the physical commodity. Depending
on market conditions, one of the factors may be more relevant than
the others. For commodities that are hard and expensive to store –
such as natural gas, crude oil and lean hogs (a commonly used type
of pork that is traded in Chicago) – the cost of storage tends to play
an important role in determining the slope of the forward curve, but
the shape of the forward curve can, at times, deviate widely from the
storage cost implied contango.
But what determines the curvature of the forward curve? That is,
what determines the difference between the 1M–2M timespread and
the 3M–4M timespread? Using the same physical arbitrage argument, it should be the cost of financing and storing a commodity for
a month starting in one month versus the cost of financing and
storing a commodity for a month starting three months from now.
310
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 311
STRUCTURAL ALPHA STRATEGIES
Hence, if having access to a storage facility now is more valued by
the market than having access to a storage facility only available in
three months, then our cost of storage argument implies a certain
concavity in the shape of the forward curve. Concavity in the shape
of forward curves suggests that the 4M contract should experience
less price decay as time passes than the 2M contract. In other words,
the price of the 4M contract falls less as it becomes the 3M contract
than the price of the 2M falls as it becomes the 1M contract. Curve
placement strategies take advantage of concavity in the forward
curves by rolling long positions in commodity futures further out in
the forward curve versus rolling short positions in commodity
futures closer to maturity. Historically, this strategy has generated
consistent outperformance and a longer date exposure produces a
better risk-adjusted return. These strategies can be implemented
with any set of weights. However, using DJ–UBS weights has been
the most popular way of implementing the curve placement strategies (see Figure 12.2).
Market segmentation across commodity forward curves
Curve placement strategies exploit differences in the market value of
storage across contract maturities, and can also take advantage of
market segmentation across the forward curve. Producers and
consumers are willing to pay a premium to protect their profit

margins against large price movements, as do index hedgers.
However, these market participants tend to favour transactions
across differing tenor segments of the forward curve.
Producers tend to hedge their long positions on the back-end of
the curve, often accepting a lower price than they would expect in
order to secure the profitability of their investments. In contrast,
consumers tend to hedge their short positions on the front-end of the
curve, often accepting to pay a premium for the physical ownership
of the commodity. Finally, index hedgers provide systematic buying
and selling pressure, selling the front-end contract and buying the
second or third most nearby contract, on a recurring basis.
Curve placement strategies benefit from market segmentation
because they roll long positions in contracts further out in the
forward curve (facing the producers as they search to offload their
natural long price risk) and roll short positions in contracts close to
maturity (facing the buying pressure created by consumers and the
index hedgers in the front-end of the forward curve).
Seasonality in curve placement strategies
Seasonality patterns can be found in a variety of commodity markets
– such as livestock, refined products, natural gas, grains, sugar
and coffee. Seasonality can then be used to enhance the risk–
return profile of curve placement strategies by leveraging the
seasonal patterns of contract liquidity, storage needs and market
segmentation.
Because of the seasonality in production, certain commodities
tend to come into the market at a very specific time of the year. For
example, corn tends to be harvested in the northern hemisphere –
where the bulk of the world production is located – between the
months of August and November. Inventories reach their lowest
point in Q3, just as the corn harvest starts in the northern hemisphere. Hence, there is seasonality in the market value of storage.
There is also seasonality in the hedging needs of consumers and
producers. For example, corn producers have to decide how much to
invest in terms of seeds, fertilisers and other production inputs
during the planting and growing seasons. In order to fix their
margins, they increase their hedging demand during the planting
season and decrease it during the harvest season. In particular,
producers start closing down their short corn futures positions on
312
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 313
STRUCTURAL ALPHA STRATEGIES
the September contract (when the harvest starts coming in) during
the months of June, July and August, exerting some buying pressure
on the September contract during those months.
Risks of curve placement strategies
One of the characteristics of curve placement alpha is that it faces
headwinds when beta commodity investments perform well. It is a
stylised feature of commodity forward curves that spot prices tend to
tilt the forward curve into backwardation as they move higher. As
demand starts outpacing supply, the spot price tends to rise and
inventories tend to draw. Lower levels of inventories should
decrease storage costs, and push down forward prices relative to
spot prices. In fact, a backwardated curve is the market’s way of
offering storage holders an incentive to supply the commodity into
the spot market. Therefore, when the market is tightening, spot
prices move up and the forward curve flattens or moves into backwardation.
This link between spot prices and the shape of the forward curve
is behind one of the most important characteristics of curve placement alpha: its negative correlation with the market. By being long
contracts with longer maturity and short the contracts on the front
end of the curve, curve placement alpha strategies tend to get hurt
when commodity prices rally. A common solution to this problem is
to use the monthly rebalancing of the curve alpha strategy to
neutralise its exposure to the market by having less notional exposure on the short leg than on the long leg. The result is a
beta-neutralised curve placement strategy. While beta neutralisation
is not a performance enhancement feature, it eliminates the negative
correlation between curve placement alpha and commodity beta. As
a result, investors are left with a purer alpha strategy that is not negatively impacted by commodity price rallies. Investors who are
looking for a more “market-neutral” strategy should neutralise their
beta exposure in their curve placement alpha strategies.
Another often proposed solution to this problem is the dynamic
allocation across maturities. If curve placement alpha suffers when
forward curves move into backwardation, then it may be better to
dynamically adjust the strategy according to the shape of the
forward curve. For instance, the investor may choose the position in
the forward curve that has the best-implied roll yield (ie, the
313
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 314
COMMODITY INVESTING AND TRADING
expected price appreciation/depreciation of the contracts as it
approaches expiry) to the contract with lower maturity. In principle,
this would give us a forward-looking estimate of how much implied
roll costs will be the following month.
However, this seems to be an overly simplistic approach. These
strategies do not seem to work in practice. The fact that these strategies fail to differentiate themselves from static exposure is illustrated
in Figure 12.3. The Dow Jones–UBS Roll Select Commodity Index,
which rolls into the futures showing the most backwardation or the
least contango, seems to underperform simple static allocations such
as the Dow Jones–UBS 5M Forward Commodity Index.
Perhaps, this is not surprising. The current “yield” or current
“implied roll cost” of a contract can only be a good predictor of its
future performance if the shape of the forward curve remains the
same. However, the slope and curvature of commodity forward
curves are not random walks and their best predictors are not their
current values. It is fairly easy to statistically reject the random walk
hypothesis for the slope and the curvature of the forward curve
across most commodities. In fact, the slope and the curvature of
commodity forward curves tend to show a large degree of mean

reversion. Hence, “yield” or “implied roll cost” strategies are
unlikely to work in practice because they do not even work in theory.
MOMENTUM STRATEGIES
Momentum strategies can be used by commodity investors as a
source of alpha in a range of different ways. For instance, many
managed futures funds (also called commodity trading advisors,
CTAs) employ computer-based algorithms that aim to identify
upward and downward price trends across a variety of markets.
Most of these algorithms work under high frequency and try to take
advantage of statistical patterns and inefficiencies not only in
commodities, but across a many futures markets. Alternatively,
momentum strategies can be profitably implemented in lowfrequency models such as those based on monthly returns.
High-frequency systematic momentum trading (as defined above)
can be a profitable strategy in certain market circumstances, and is
likely to be a diversifying strategy on a broad portfolio of alpha trades.
However, they are hard for investors to access outside of a fund
format. Low-frequency momentum, on the other hand, can be easily
implemented. Most importantly, high-frequency momentum and
low-frequency momentum are not competing strategies, but rather
complementary on a broad basket of commodity alpha strategies.
Where does low-frequency momentum come from? For
commodities such as crude oil, refined products and base metals,
momentum comes from their cyclical nature – that is, from the fact
that demand follows the upward and downward trends of the business cycle (see Figure 12.4). More broadly, persistence is a direct
consequence of determined demand growth combined with the
inability of production to respond immediately to demand shocks, in
addition to low short-term elasticity of supply. Hence, momentum
results from persistence in the supply and demand fundamentals of
the commodity.
Given that changes in inventories are the differences between
supply and demand, momentum in commodities results from a
sustained trend in the levels of inventories. As such, we should find
an even stronger link to the shape of the forward curve. In fact, statistical analysis shows momentum in the shape of the curve seems to be
more prevalent and easier to detect than momentum on returns (see
Figure 12.5).

Whether using excess returns, momentum or momentum based
on the shape of the curve, momentum strategies exploit persistence
in the levels of inventories. Months of low inventory levels – which
are associated with backwardation, low roll costs and rising prices –
316
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 317
STRUCTURAL ALPHA STRATEGIES
tend to be followed by months of low inventories. Hence, positive
price performance and low roll costs are likely to be persistent.
Similarly, months of high inventory levels – which are associated
with contango, high roll costs and falling prices – tend to be followed
by months of high inventories. Momentum generates alpha by identifying the commodity markets that need to create persistent
incentives for the market to balance supplies with demands. The
strategy is then rewarded for taking price risk in anticipation of
future price movements. In that regard, momentum strategies are
not pure alpha strategies designed to be market-neutral at all times,
quite the contrary; in times of price appreciation, momentum strategies would be expected to participate – and have notable positive
correlation – with the market. In times of price declines, short positioning would result in negative correlation with the market.
Still, momentum strategies do not have an inherent bias to one
side or another, and in that sense are market-neutral alpha strategies.
The drawback of momentum strategies is that they are only likely to
generate returns when markets are trending, and are less likely to
generate much alpha in range-bound markets.
While price and curve momentum strategies roughly exploit the
same source of alpha, there is an important difference when it comes
to implementation. Momentum can be used as a relative value signal
that generates cross-commodity alpha by selecting which commodities to go long. For instance, some strategies select the most
“backwardated” commodities or the least “contangoed” to construct
a long-only portfolio. These are relative momentum strategies that
allow investors to pick the best–performing commodities, imposing
the constraint to be 100% long at all times.
However, one can also use momentum as an absolute value indicator – ie, as a signal to be used when deciding whether to go long or
short a particular commodity. A portfolio using an absolute
momentum strategy does not need to be 100% long at all times.
Unlike relative momentum strategies, a portfolio using this type of
implementation could be long for some commodities without any
offsetting short positions. Similarly, the portfolio could have only
short positions or stay neutral depending on the combination of
signals it receives.

COMMODITY INVESTING AND TRADING
VOLATILITY STRATEGIES
Commodity volatility can also provide a powerful source of alpha
for investors. Just as in any other derivatives market, implied
volatility in commodity markets serves as the key parameter for
market participants – such as producers, consumers, processors and
investors – to match the supply and demand for options. However,
there is often a structural imbalance between buyers and sellers of
options in most commodity markets.
Market participants’ hedging needs cause persistent biases in the
commodity options markets, offering a source of market-neutral
alpha for investors. Commercial market participants are natural
buyers of insurance against large price swings – ie, buyers of
volatility. Producers and consumers are willing to pay a premium to
protect their profit margins against large price movements. At the
same time, there are few natural sellers of volatility in the
commodity options markets apart from speculators.
Because of the relatively low participation of speculators in
commodity options markets, this imbalance between buyers and
sellers of volatility has helped to create structural alpha opportunities for investors. For market participants willing to take on price
risk, there is an opportunity to profit from this demand for insurance. Generally, there is high demand for long option positions
among commercial market participants, such as producers,
consumers and distributers.
Option sellers collect the premium of an option and often delta
hedge their exposure to the underlying contract. However, at inception, option sellers do not know whether the final profits of delta
hedging the position will be positive. The difference between the
option price change and the profit or loss of the underlying delta
hedge is the hedging error that affects the profit and loss (P&L) of
selling options and delta hedging. Hence, option market makers
need to be compensated for the risk of losing money on their delta
hedges.
This hedging risk is a function of the “gamma” of the option, as
well as the future realised price volatility of the underlying future.
As a result, option prices (and consequently implied volatility) need
to be high enough to compensate market makers for the risk of
volatility realising at high levels over the lifetime of the option. While
the high demand for options from commercial players pushes up
318
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 319
STRUCTURAL ALPHA STRATEGIES
implied volatility away from realised volatility, current realised
volatility is an estimate of the risk of delta hedging. Hence, the
implied versus realised volatility spread can be seen a measure of the
implicit supply and demand for volatility in the options market. As
the P&L of delta hedging short options positions is linked to the
spread between implied and subsequently realised volatility, option
market markers then embed a premium on implied volatility over
realised volatility.
Investors can benefit from the imbalances between buyers and
sellers of commodity volatility through variance swaps. The payout
of a variance swap depends directly on the difference between
implied volatility and the subsequently realised volatility of the
underlying asset. Hence, commodity variance swaps can be utilised
to take advantage of the structural premium between implied and
realised volatility in commodities. Systematic variance selling offers
a sources of structural alpha for investors. A variance swap can be
sold short at the close of the day that the previous swap expires so
that short variance positions can be rolled over continually (see
Figure 12.6).
Selling variance is vulnerable to large price movements common
in many commodity markets. One way to mitigate this risk is to
hedge the short variance position with a long variance position with

longer maturity, further out in the volatility term structure. Such
calendar spread variance swaps can be used to create consistent
structural commodity alpha strategies in many commodity markets.
Combining strategies with different tenors and then adjusting
notionals to make the exposure less sensitive to changes in implied
vols – ie, vega neutral – is a classic way of mitigating the tail risk in
short volatility strategies.
Options have convex payouts and their price movements are not
exactly equal to the movements in the underlying delta hedge. The
more convex the option, the harder it is to delta hedge, the higher
risks the option seller faces and the higher the compensation for
bearing those risks should be. Hence, the alpha generated by systematically selling variance should be proportional to the degree of
convexity of the option payout function – ie, to the option’s
“gamma”. As a result, systematically selling variance in short maturity tenors should outperform systematically selling variance in long
maturity tenors. This is so because the short-dated options have
higher gamma than long-dated options, everything else being
constant. Similar “gamma” strategies can also be used to generate
structural commodity alpha in many commodity markets (see Figure
12.7).

STRUCTURAL ALPHA STRATEGIES
PUTTING IT ALL TOGETHER
The objective of any alpha portfolio should be to capture the benefits
that a diversified portfolio of different sources of alpha can provide.
In general, a portfolio’s risk is a function of the number of strategies
held in the portfolio as well as of the correlation between them.
Hence, a portfolio of a few alpha strategies, more or less independent
from each other, generally will produce better risk-adjusted returns
than any single strategy by itself.
A simple example illustrates the power of a diversification in an
alpha portfolio. Suppose we have an alpha strategy (strategy A) that
generates returns of 5% and volatility of 2% per annum, providing an
information ratio of 2.5. At the same time, suppose we have a set of
three uncorrelated strategies (strategies B, C and D), each generating
annual returns of 3% with the same 2% volatility, each of these
providing an information ratio of 1.5. Despite each of those strategies
being far worse than strategy A on an individual basis, it turns out
that an equally weighted portfolio of strategies B, C and D produces
a better allocation in risk-adjusted terms than an allocation to
strategy A.
Backtesting bias
In any historical backtest, it is hard to identify whether the good
historical performance of a strategy is a product of its design or pure
luck. This is a classic problem with backtests and other types of
model-selection algorithm. By searching for the alpha holy grail, we
may end up spuriously choosing a methodology that would have
performed well in that period by sheer luck. Complex strategies may
perform well on a backtested basis not because of any fundamental
reason, but only because their many bells and whistles were chosen
so the strategy would perform well on the backtest in the first place.
In fact, a set of sufficiently complex rules can overfit history and give
any strategy a great backtest.
One way to mitigate the risk of backtesting bias is to always
choose simple implementations of each investment theme. Simple
strategies have fewer degrees of freedom and therefore are likely to
suffer less from the overfitting problem that complex strategies
intrinsically embed. Overfitting rules and parameters are what ultimately generate the backtesting bias. Investors are better off
combining simpler strategies – potentially with worse backtested
321
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 322
COMMODITY INVESTING AND TRADING
performance, but for which they can understand the sources of
returns – than more complex versions of the same strategy.
The three major investment themes in the structural commodity
alpha space outlined above – curve placement, momentum and
volatility – can be accessed through extremely simple rules-based
strategies. Of course, one could think of many ways to try to improve
the performance of these simple strategies. However, in practice,
many of the more complex strategies only marginally improve the
risk-adjusted returns of the simpler strategies. At the same time,
simpler strategies are less vulnerable to the backtesting bias problem
purely because they have less rules and parameters to be calibrated.
Weaving an alpha basket
The simple example above suggests an easy methodology for
creating high-quality alpha in any asset class. Using simple strategies, investors should create an alpha portfolio that captures
different sources of risk premium. Generally, the diversified alpha
portfolio will produce better risk-adjusted returns than any single
strategy if the strategies are combined in an optimal way.
However, what are the weights that should be given to each alpha
strategy when constructing a portfolio of alpha strategies? The
concept of “basket weights” is somewhat meaningless for
commodity alpha investments. What really matters is not “notional
weight” but “volatility weight” – ie, the contribution of each strategy
to the overall risk of the portfolio.
To make alpha strategies comparable, investors can dynamically
adjust the allocation to the strategy in order to target a desired level
of volatility. This technique, called volatility targeting, is a means of
creating a level playing field for different alpha strategies. Because
commodity alpha strategies are typically unfunded, changing the
degree of participation is only limited by the amount of collateral
needed to fund the strategy.
On the level playing field of volatility-targeted strategies, how do
we then best combine different sources of commodity alpha into a
single alpha portfolio? After defining expected returns and a
measure of risk (eg, volatility) for every alpha strategy, we can
construct an efficient frontier by finding the portfolio that maximises
expected returns for a given amount of risk. Because commodity
alpha strategies are unfunded, the weights of a commodity alpha
322
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 323
STRUCTURAL ALPHA STRATEGIES
portfolio do not need to add to 100% as they do in the classic
Markowitz’s efficient frontier problem.1 In the absence of any weight
constraint, the efficient frontier for commodity alpha portfolios is a
straight line in which all portfolios have exactly the same information ratio as that of the maximum-information ratio portfolio (MIP)
of a frontier obtained with portfolio weights constrained to add to
100% (see Figure 12.8).
However, defining expected returns and a measure of risk for
each commodity alpha strategy involves the real problem of trying to
optimise different sources of commodity alpha into a portfolio. That
is, it is a statistical rather than a financial issue. One way to avoid the
statistical difficulties relating to asset allocation decisions is to simply
put statistics aside and follow an appropriate rule of thumb. On the
level playing field of volatility-targeted strategies, an equally
weighted (EW) basket is a straightforward way to combine
commodity alpha strategies. One advantage of the EW basket is its
robustness over time, as the information ratios of the EW basket tend
to be more stable than the ones for individual strategies. However,
the EW basket is more than just a naïve diversification technique.
In our selected set of commodity alpha strategies, a case could be
made for all pairwise correlations being zero on average. After all,
Figure 12.8 The application of CAPM to commodity alpha suggests that
investors should only care about the “Maximum Information Ratio Portfolio”

the strategies were designed to be more or less independent sources
of alpha. If that is the case, then on the level playing field of volatilitytargeted strategies, we know that the EW basket is one with weights
adding up to 100% with the lowest level of volatility. Formally, if all
pairwise correlations are equal to zero and the volatility of each
strategy is equal to s, then the EW basket is the portfolio with
weights adding to 100% with the lowest level of volatility. Under
those assumptions, this is the minimum-variance portfolio (MVP).
Of course, the weights of a commodity alpha portfolio in the efficient frontier do not need to add to 100%. However, once the MVP is
found, investors can leverage weights up and down proportionally
to achieve any level of targeted volatility on the overall portfolio. In
practice, this technique can get investors quite close to the MIP
without having to ever care about estimating expected returns of
commodity alpha strategies (see Figure 12.9).
CONCLUSION
Systematic commodity alpha strategies attempt to capture different
risk premiums, such as insurance and liquidity, prevalent in
commodity markets. These systematic strategies capture risk
premiums that are structural to commodity markets and therefore
324
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 325
STRUCTURAL ALPHA STRATEGIES
likely to be a robust source of market-neutral returns in the long run.
In addition, a portfolio of alpha strategies more or less independent
of each other will yield higher risk-adjusted returns than any standalone, single commodity alpha strategy. This paves the way for a
simple recipe for generating high-quality alpha in commodities.
Investors should pursue simple and easy to understand strategies
that exploit a broad range of sources of alpha. In particular, using
equally weighted baskets of volatility-targeted strategies is a simple
and robust way to construct a long-term allocation to structural
commodity alpha strategies.

APPENDIX: PUTTING MOMENTUM INTO COMMODITIES
Paul D. Kaplan
Strategies that take a momentum-based long/short approach to
commodity investing serve investors better than long-only strategies. Following weaker investor activity in 2011, investment flows
into commodities grew in 2012, with a net inflow of US$5.3 billion
across all sectors alone in August 2012, with commodity exchangetraded products (ETPs) one of the fastest-growing asset classes.
Commodity ETPs hit an all-time high of US$207.4 billion total assets
in September 2012. In comparison, commodity ETPs saw inflows of
US$10 billion throughout the entire year of 2011, and the year ended
with total assets in commodities ETPs of US$152 billion.
This surge in assets mirrors equally impressive gains in many
commodities’ spot prices. Unfortunately, and to the chagrin of many
investors, products linked to commodity indexes often experience
much lower returns. Negative roll yield (which occurs when distant
delivery prices exceed near delivery prices) means that many
investors lose out even as prices rise. In response, a growing number
of commodity investors are eschewing the traditional long-only
approach in favour of alternative strategies that are better able to
manage roll yield.
With the rise of more innovative strategies, there is reason to question how well investors are being served by the traditional long-only
commodity indexes either as benchmarks or proxies for investment
325
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 326
COMMODITY INVESTING AND TRADING
products. Traditional approaches to representing pure beta exposures work well for stocks and bonds but not so well for the
commodities “asset class”. In fact, we argue that there is no such
thing as commodity beta. Moreover, we also assert that new passive
strategies that use a momentum-based long/short approach rather
than the long-only approach of the most common commodity
indexes are better benchmarks for active strategies.
NO SUCH THING AS COMMODITY BETA
For many asset classes, it is very easy to take a pure beta exposure.
Multiple asset class proxies are available, many of which are reasonable substitutes for each other. The Russell 3000, S&P 500 and Dow
Jones Wilshire 5000 indexes, for example, are representative of the
broad stock market and have similar performance characteristics,
just as the Citigroup Broad Investment-Grade (BIG), Barclays Capital
US Aggregate and Merrill Lynch US Domestic Master bond indexes
mirror the wider fixed income market and perform alike. However,
for commodities fewer choices and more disparity exist among the
index options.
NOT ALL INDEXES ARE ALIKE
Figure 12A.1 illustrates the similar risk and return characteristics of
the broad stock and bond indexes and the disparity among the three
traditional commodity indexes – the S&P GSCITM Commodity
Index, Dow Jones UBS Commodity Index, and Reuters/Jefferies
CRB Index. When we plot standard deviation and compound annual
return for each index over a common time period (January 1991–
September 2012), we see that the nearly identical risk and return
characteristics of both the stock and bond indexes place the plot
points on top of one another. The commodity indexes, however, do
not display the same level of consistency. Dramatic differences in
constituents and weighting schemes as well as rebalancing rules are
likely the cause of the performance differences in the commodities
indexes. The S&P GSCI index, for example, has about double the
weighting to the energy sector as the Dow Jones UBS Commodity
and Reuters/Jefferies CRB indexes and only one third of the
weighting to agriculture.

BOTH LONG AND SHORT POSITIONS FOR POSITIVE RISK
PREMIUMS
Long-only commodity futures strategies can prove inadequate in
providing investment exposure to commodities, which is why
professional CTAs tend to take both long and short positions in
commodity futures, often based on trends in prices.
SOURCES OF EXCESS RETURN
A futures strategy generates excess return (ie, return in excess of the
risk-free rate) from two sources:
327
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 328
COMMODITY INVESTING AND TRADING
1.

changes in futures prices; and
the roll yield – which can be either positive or negative – that
results from replacing an expiring contract with a further out
contract in order to avoid physical delivery yet maintain positions in the futures markets.
A complete understanding of these two sources of return requires an
analysis of three interrelated markets for each commodity:
1.
2.
3.
spot market – the cash market for the commodity itself;
futures market – the market for contracts to deliver the
commodity in the future for a price set today; and
storage market – the market for the service of storing the
commodity on behalf of its owner.
What happens in spot markets is important to futures investors
because changes in spot prices impact futures prices. The storage
market is important because it interacts with the spot market and
influences the slope of the futures price curve, which is the source of
roll yield.
At times of high demand, spot prices will be strong and the
futures price will be lower than the spot price so that the further out
the futures contract, the lower the price. When this is the case, we say
that there is “backwardation” in the futures market or that the
futures curve is “backwardated.” Investors who are taking long positions in futures contracts can realise this compensation monetarily by
replacing the contracts that they are holding with longer-term ones,
thus locking in profits.
This component of excess return realised by investors is referred
to as “roll yield”. As Figure 12A.2 shows, in backwardated markets
roll yields are positive. Likewise, when the marginal benefits of
owning spot supplies are low, the relationship between time to expiration and the futures price is positive, a condition known as
contango. In contango markets, roll yields are negative because
replacing contracts with ones of later maturity results in locking in a
loss.
When a commodity is scarce spot prices are strong, leading to
backwardation and positive roll yields. Conversely, plentiful spot
supply leads to contango and negative roll yields. Since inventory

conditions in some commodities are slow to adjust due to the time it
takes to increase their production, backwardation or contango could
persist for a period of time, causing investors to consistently experience positive or negative roll yield over the period. Thus, a passive
investor should benefit from a trend-following strategy that incorporates roll yield into its signal.
329
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 330
COMMODITY INVESTING AND TRADING
ROLL YIELD AND EXCESS RETURN
The effect of roll yield on excess return can be substantial. In fact,
several studies have shown that excess return is attributable
primarily to roll yield, not to changes in futures prices. Long-term
excess returns on commodities that exhibit mean reversion in price
and that tend to trade in contango will generally be negative, and
those that tend to trade in backwardation will generally be positive.
This behaviour can be seen in Figure 12A.3, which shows the relationship between roll yield and excess returns on the commodities
listed for the 21-year period April 1990–September 2011.
Commodities that tended to trade in contango experienced negative
excess return, while those that tended to trade in backwardation saw
positive excess return.
Of particular interest here are natural gas futures. Because the
price of natural gas grew at 4.1% per year over the 21-year period,
one might have expected a natural gas futures index to provide a
comparable rate of return. However, because natural gas futures
traded in contango (and consequently experienced negative roll
yield), the excess return was an abysmal negative 12.5%.

indexes can better serve investors by attempting to capture the full
excess return from a futures strategy. Such passive strategies are also
likely to prove a better benchmark for the active strategies of professional futures investors.
To make this idea operational, we created a family of commodity
indexes that includes combinations of long commodity futures, short
commodity futures and cash (see Figure 12A.4). The primary index,
called the Morningstar Long/Short Commodity Index, holds
commodity futures both long and short based on momentum
signals. The other indexes are derived from this long/short index.
The family includes a long/flat version, which holds cash in place of
the short positions in the primary version so that investors who do
not want or cannot have short positions can still get some benefits of
a momentum-based long/short strategy. The family also includes a
short/flat version for investors who already have long-only exposure to commodities and want some benefits of the momentum
strategy without having to replicate or drop their long-only
exposure.
We created a set of single commodity indexes to serve as
constituents for the long/short index and the related composite
indexes by calculating a “linked” price series that incorporates
both price changes and roll yield. The weight of each individual
commodity index in each of the composite indexes is the product
of two factors: magnitude and the direction of the momentum
signal. We initially set the magnitude based on a 12-month
average of the dollar-weighted open interest of the commodity.
We then capped the top magnitude at 10% and redistributed any
overage to the magnitudes for the remaining commodities. The
direction depends partly on the type of composite index and, as
we explain below, partly on the type of commodity in the long/
short index.
In the long/short index each month, if the linked price exceeds its
12-month daily moving average, the index takes a long position in
the subsequent month. Conversely, if the linked price is below its 12month moving average, the index takes the short side. An exception
is made for commodities in the energy sector. If the signal for a
commodity in the energy sector is short, the weight of that
commodity is moved into cash – that is, we take a flat position.
Energy is unique in that its price is extremely sensitive to geopolitical

DOWNSIDE PROTECTION
While all long-only commodity indexes tend to provide strong
protection when the stock market is down and in inflationary environments, the Morningstar Long/Short Commodity index limits
downside risk while negotiating ups and downs in the commodity
markets themselves. The Long/Short index’s maximum drawdown
in the February 1991–September 2012 period, as seen in Figure 12A.5,
was substantially lower than that of the S&P GSCI and Dow Jones–
UBS Commodity indexes. We also compared maximum drawdowns
experienced by the listed indexes during five-year sub-periods
within that overall period, and the Morningstar Long/Short
Commodity index suffered much smaller drawdowns in all subperiods. Clearly, a long/short strategy is better equipped to tap into
334
12 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:03 Page 335
STRUCTURAL ALPHA STRATEGIES
the underlying momentum of commodity prices, thereby limiting
losses in down markets.
THE LONG AND SHORT OF IT
The long-only strategies that dominate the commodity index market
do not best serve investors as investment vehicles or as benchmarks.
Since futures price changes and roll yields are the sources of excess
return, long-only indexes have no way to capture the returns available from shorting futures when there is downward price pressure
or a positively sloped futures price curve. Long-only indexes
generate negative roll yields when markets are in contango (when
distant delivery prices exceed near delivery prices), and thus can
have negative returns when commodity prices are rising.
Furthermore, since many actively managed CTAs invest in long and
short futures based on momentum trading rules, the long-only
indexes are not appropriate benchmarks, rendering traditional
approaches to representing beta exposure unsuitable.
By using a momentum-based approach that takes into account
both price change and the slope of the futures price curve, these
Morningstar indexes aim to maximise both sources of excess return –
price change and roll yield – to produce better performance. In addition, these indexes are logically consistent with the underlying
economics of commodities futures markets, and backtested results
show an attractive risk profile, low downside risk and low correlations to both traditional asset classes and long-only commodity
indexes. As passive investment alternatives, these rules-based
indexes could offer easier access to actively managed commodities
trading strategies.

Selection” (Journal of Finance, 7(1), March) was among the first to address the problem.

Energy Index Tracking
Kostas Andriosopoulos
ESCP Europe Business School
In this chapter, a geometric average Spot Energy Index (SEI) will be
constructed before its performance is reproduced with stock portfolios. The investment methodology employs two self-adaptive
stochastic optimisation methods, superior to other rival approaches
when applied to this index-tracking problem. To test the performance of the tracking baskets, three different rebalancing scenarios
are examined, that also take transaction costs into consideration. It
will be shown that energy can be effectively tracked with stock portfolios selected by the investment methodology used here.
Passive investment strategies are becoming increasingly popular.
Sharpe (1991) argues that, on average, active managers cannot beat
passive strategies and active trading strategies are a zero-sum game.
Other studies have found that passive strategies outperform active
strategies on average (Malkiel, 1995; Sorenson et al, 1998; Frino and
Gallagher, 2001). In addition, Barber and Odean (2000) claim that in
active trading strategies the presence of high transaction costs, and
sometimes the overconfidence of investors in their predictions,
reduces profits substantially and potentially leads to losses.
One of the most popular forms of passive trading strategies, index
tracking, attempts to replicate/reproduce the performance of an
index. Portfolio managers can choose between two methods. Full
replication, purchasing all the stocks in an index, has some practical
limitations and disadvantages. According to Beasley et al (2003),
replicating exactly an index entails frequent revisions1 to reflect the
updated weightings in the index, leading to high transaction costs.
337
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 338
COMMODITY INVESTING AND TRADING
One-to-one replication also suffers from the disadvantage that some
stocks can be very illiquid. For these reasons, many passive strategy
managers prefer the alternative of partial replication, where
managers hold the subset of stocks chosen to replicate the index most
effectively.
Since the early 2000s, impressive gains have been witnessed in
commodity prices. This has attracted investors’ attention and led to
growth of index investing in the commodity markets. In general,
there are three major ways of investing in a commodity index: first,
by choosing an index and replicating it by following the related rule
book; second, by investing in a fund that replicates the chosen index;
finally, a popular approach is buying the shares of an exchangetraded fund (ETF) that mimics the commodity index. This trend
toward commodity index investing prompted the first commodity
ETF in November 2004.2 As of January 2010, the market capitalisation of ETF exceeded US$39 billion. Many other ETFs investing in
physical commodities, futures and commodity-related equities have
followed.
This chapter will propose a new approach that reproduces the
performance of a geometric average SEI by investing only in a subset
of stocks from various equity pools. For the purposes of our analysis,
the Dow Jones Composite Average, the FTSE 100 and Bovespa
Composite indexes, and two pools that include only energy-sector
stocks from the US and the UK, respectively, are used. Daily data are
analysed and the index-tracking problem addressed by two evolutionary algorithms – the differential evolution (DE) algorithm and
the genetic algorithm (GA). The performance of the resulting investment strategy is tested under three different scenarios:
buy-and-hold, quarterly and monthly rebalancing, accounting for
transaction costs.
This chapter has the following structure. The next section will
discuss the importance of commodity index investing and major
innovations, before we present the innovative approach used in this
chapter for replicating the price behaviour of an energy commodity
index using equities. We then explain in more detail the optimisation
model, describing the two evolutionary solution techniques
employed. The following section will outline the methodology used
for developing the constructed energy commodity index, along with
the commodity and equity data used, and discussion of the results
338

ENERGY INDEX TRACKING
from tracking the energy index with the proposed investment
approach will then follow.
COMMODITIES INDEX INVESTING
Commodity indexes have been around for many years, used mostly
for benchmarking and to track spot commodity prices. One of the
first published commodity indexes was the Economist’s
Commodity-Price index, which started in 1864. Then, in 1957, the
Commodity Research Bureau (CRB) index was established, tracking
spot commodity processes; after undergoing major revisions in its
composition, it is still published today. Nevertheless, since the early
1990s, the development of commodity indexes has witnessed
tremendous changes. The first generation of investable commodity
indexes appeared only in 1991, when the S&P GSCI (originally the
Goldman Sachs Commodity Index) was introduced. In 1998, the
Dow Jones–UBS Commodity Index (originally the Dow Jones–AIG
Commodity Index) and the Rogers International Commodities Index
(RICI) were both launched. Both the S&P GSCI and the RICI indexes
are heavily weighted towards the energy sector, while the Dow
Jones–UBS, because of the rule that no sector can weigh more than
one-third of the index, has energy at its limit; in many instances, this
limit is exceeded between the annual rebalancing periods.
The common characteristic, and a major disadvantage of these
early indexes, is that they invest in commodity futures contracts that
are close to expiration, thus they roll forward their futures positions
more frequently – making it very expensive to follow an indexreplication strategy using ETFs. In addition, holding a long futures
position via an index that invests in the front of the curve is suboptimal, especially latterly, because many commodity futures curves
have been experiencing steep contango (a state when the futures
price curve is upward sloping) at the front end of the curve, which
diminishes the ultimate returns.
This previous observation was the main driver behind the creation
of the so-called “second-generation” commodity indexes such as the
UBS Bloomberg Constant Maturity Commodity Index and the JP
Morgan Commodity Curve Index. Both of these indexes have a
constant weighting scheme across commodities, but their investments allocation is spread across several contract expirations within
individual commodities. The DJ–UBSCI 3-Month Forward index
339
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 340
COMMODITY INVESTING AND TRADING
takes a similar approach and invests in contracts farther out the
futures curve, reducing the effect of backwardation (a state when the
futures price curve is downward sloping) or contango as the curve
tends to be flatter for longer maturities. These type of indexes outperform the first-generation indexes because, when the front end of the
curve is in steep contango, as has been the case with crude oil, the
losses tend to be mitigated or reversed across the longer maturity
contracts. Nonetheless, the opposite happens when futures markets
are in backwardation, since the concentration usually occurs at the
front end of the curve. It can be argued, however, that the chronology
of the indexes has a significant impact on their construction methodology, and hence their performance, as later ones have had the
benefit of improving on the methodology used by previously developed indexes.
The latest addition to the family of commodities indexes are thirdgeneration indexes that attempt to improve the returns of the
previous two by incorporating commodities selection, overweighting or including only commodities that are expected to
deliver higher returns in the near future, while underweighting or
omitting completely commodities that are expected to perform
poorly. The UBS Bloomberg CMCI Active Index introduced in 2007
and the SummerHaven Dynamic Commodity Index introduced in
2009 are two examples of the third-generation commodity indexes.
The latter index includes 14 equally weighted commodities from a
total of 27, rebalancing its futures portfolio every month using basis
and momentum to identify the greatest possible risk premium. The
former index, on the other hand, uses the discretionary approach of
its research analysts who adjust the component weightings of the
index according. However, these types of indexes carry with them a
new risk since the method of the research analysts used to select the
commodities and their respective weightings can be unsuccessful,
and thus underperform passive indexes.
Commodity indexes attempt to replicate the returns equivalent to
holding long positions in various commodities markets without
having to actively manage the positions. Being uncorrelated with the
returns of traditional assets such as stocks and bonds, commodity
index investments’ returns provide a significant opportunity to
reduce the risk of traditional investment portfolios. This explains the
economic rationale for including a commodity index investment in
340
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 341
ENERGY INDEX TRACKING
institutional portfolios such as those of pension funds and university
endowments. There are now numerous publicly available futures’
indexes, with different risk and return profiles, offering exposure to
commodity markets; each of these indexes also offers specific exposure to certain commodity sectors via their traded sub-indexes.
Commodity index investing is still relatively “young” – compared
to other more established asset classes such as stocks and bonds –
and we would expect continued interest and innovation by market
players in the coming years.
AN INNOVATIVE APPROACH
The above addresses a question that has received almost no attention
in the literature: can returns of equity portfolios be used to replicate
the performance of physical energy price returns, proxied by a spot
index? The aim of this chapter is to replicate the price behaviour of
direct energy commodity investment using equities. The proposed
approach is based on previous research findings that the returns of
equally weighted long-only portfolios of commodity futures are
similar to those of stocks (Bodie and Rosansky, 1980; Fama and
French, 1987; Gorton and Rouwenhorst, 2006). In addition, after the
2000s, commodities went through a financialisation process,
exposing them to the wider financial shocks (Tang and Xiong, 2010).
The replication method uses two very efficient strategies, the DE
algorithm and the GA, to solve the index-tracking problem for the
constructed SEI. These low tracking-error strategies provide several
advantages to investors: they result in better-diversified portfolios,
make the long-only constraint of a fund manager less binding and, in
general, tend to provide higher returns for equity strategies.
The performance of the SEI is reproduced by investing in a small
basket of stocks picked either from the stocks comprising three wellknown financial indexes, or from two pools of energy-related stocks.
In particular, the cases of the US, UK and Brazilian investors are
considered under the assumption that they want to invest in the SEI
and prefer to access only their local stock markets due to cost savings
and/or better knowledge of the respective markets. They represent
two developed and one developing stock market, with the latter
having its unique energy significance in the global scene. Reforms
and regulations that have taken place in Brazil have brought transparency, sophistication and additional liquidity to its financial

markets. Oil and other energy prices influence companies’ earnings
and thus their stock prices. Hence, based on intuition and previous
research findings, the two pools of energy-related stocks used in the
analysis should perform very well in tracking the SEI. Moreover, the
stocks of various companies operating in other, non energy-related
industries will still be affected by the movements in energy prices.
The methodology implemented can track the SEI or any other benchmark index by investing in a basket of stocks that each of the
evolutionary algorithms will determine. Baskets of a maximum of
10, 15 and 20 stocks are selected from the following stock pools: Dow
Jones Composite Average, FTSE 100, Bovespa Composite, and the
two pools of energy-related stocks from the US and the UK stock
markets.
The SEI represents a basket of energy commodities and serves as a
performance benchmark with limited ability for direct investment.
However, the proposed approach provides investors with an option
to track the performance of this SEI using a basket of equities that are
liquid and fully investable. This allows investors to get closer to the
underlying commodity market price trends, something they cannot
achieve using a futures price index. Historically, futures index
returns have lagged price index returns, with this decoupling of
performance being a constant frustration for index investors. For
comparison, the performance of two well-established energy excess
return indexes are reported, namely the Dow Jones–UBS Energy
Sub-Index and the Roger’s Energy Commodity Index, against the
performance of the constructed SEI and the selected portfolios.
This chapter’s findings have several positive implications for
investors. They provide a low cost – compared to actively managed
funds – means of accessing the energy spot markets. In particular,
sector rotation investment managers can benefit from the findings.
By tactically shifting assets, they can over- or under-weigh specific
sectors according to their economic outlook or market objective.
Index tracking and problem formulation
In the search for optimally replicating an index, different studies
(Gaivoronski et al, 2004; Frino and Gallagher, 2001) focus on the
performance deviations of the tracking portfolio – ie, the tracking
error. Additionally, single-factor and Markowitz models (Larsen-Jr
and Resnick, 1998; Rohweder, 1998; Wang, 1999) have been used to
342
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 343
ENERGY INDEX TRACKING
replicate the performance of an index. Furthermore, the use of the
cointegration concept in building portfolios for index tracking is
highlighted by Alexander and Dimitriu (2002) and Dunis and Ho
(2005).
This chapter follows the approach used in Andriosopoulos et al
(2012) for reproducing the performance of an international market
capitalisation shipping stock index and two physical shipping
indexes by investing only in US stock portfolios. First, the tracking
error is measured through the root mean square error (RMSE) criterion. In particular, is assumed that there exist price data on N stocks
and the price of an index over an (in-sample) time period [1, 2, …, T].
The goal is to create a tracking portfolio consisting of at most K stocks
(K < N) that replicates, as closely as possible, the index for an (out-ofsample) period [T + 1, T + Δt]. The replication error of the tracking
portfolio is defined as follows:
T
! (r ! R )
RMSE =
t
2
t
/T
(13.1)
t=1
where rt and Rt are the returns for the tracking portfolio and the
index, respectively.
Second, except for the replication error, the return of the tracking
portfolio is also of interest. To this end, the mean excess return (ER) is
considered over the benchmark index, defined as follows:
T
ER = " ( rt ! Rt ) /T
(13.2)
t=1
Let Pit denote the price of stock i at time t, C the available capital and
xi the number of units bought of stock i. The complete formulation of
the objectives and constraints used to solve the index tracking
problem can then be expressed as follows:
Minimize: f = ! ! RMSE " (1! ! ) ! ER
Subject to:

(13.7)
where 0 ≤ l ≤ 1 is a user-defined parameter that outlines the tradeoff between the two objectives (tracking error and excess return). In
the case l = 1, the tracking portfolio has as its objective to minimise
the tracking error (pure index tracking), whereas when l = 0, the
portfolio’s goal is to maximize the excess return. Constraint 13.4
guarantees that the value of the portfolio at the end of the in-sample
period is equal to the available capital C. This budgetary limitation
ensures that for all alternative tracking portfolios an identical
amount C is invested at the beginning of the out-of-sample period.
Constraint 13.5 associates a binary variable zi to each stock i, which
is used to consider whether stock i is included in the tracking portfolio (zi = 1) or not (zi = 0). The parameter e is used to impose a
lower bound on the proportion of the capital invested in each stock
(in this study e is equal to 0.01). Finally, constraint 13.6 defines the
maximum number of stocks K that can be included in the tracking
portfolio.
Evolutionary solution techniques
The optimisation model of equations 13.3–13.7 is a complex combinatorial problem that is difficult to solve with analytical techniques.
Thus, evolutionary algorithms have become particularly popular in
this context. Evolutionary algorithms were first used for addressing
the index-tracking problem by Goldberg (1989), who apply a genetic
algorithm for index replication. More recent applications of genetic
algorithms in index-tracking and portfolio optimisation can be found
in the works of Oh et al (2005), Chang et al (2009) and Soleimani et al
(2009). Beasley et al (2003) propose an evolutionary population
heuristic, accounting for transaction costs and the possibility for revision of the tracking portfolio. Their results indicate that deriving the
optimal portfolio directly from past data and not from the distribution of stock returns ultimately achieve better results. Maringer and
Oyewumi (2007) apply DE for tracking the Dow Jones Industrial
Average assuming different cardinality constraints in their selected
344
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 345
ENERGY INDEX TRACKING
portfolios. They report that the maximum number of stocks included
in the tracking portfolio must be roughly 50% of the benchmark
index to achieve good results; any additional stocks only marginally
improve the algorithm’s performance. The DE algorithm has also
been used in other studies using hybrid and multi-objective schemes
(Krink et al, 2009; Krink and Paterlini, 2011), as well as in the context
of loss aversion (Maringer, 2008) and mutual fund replication
(Zhang and Maringer, 2010). Other proposed algorithmic procedures include immune systems (Li et al, 2011), hybrid algorithms
(Ruiz-Torrubiano and Suárez, 2009; Scozzari et al, 2012), robust optimisation (Chen and Kwon, 2012) and mixed-integer programming
formulations (Canakgoz and Beasley, 2008; Stoyan and Kwon, 2010).
An overview of different methods can be found in WoodsideOriakhi et al (2011).
In the context of this chapter, the DE algorithm and a genetic algorithm are employed. Both are well established in the computational
intelligence literature, easy to implement and well suited for
complex financial optimisation problems, particularly in the context
of index tracking and constrained portfolio optimisation. The application of both algorithms enables the examination of the robustness
of the results under different solution approaches.
GAs are probably the most popular evolutionary techniques. They
are computational procedures that mimic the process of natural
evolution for solving complex optimisation problems (Goldberg,
1989). A GA implements stochastic search schemes to evolve an
initial population (set) of solutions through selection, mutation and
crossover operators until a good solution is reached.
Similarly to the GA framework, DE is also a stochastic optimisation method. It was developed by Storn and Price (1995) as an
alternative to existing metaheurtistic approaches, and it is well
suited to continuous optimisation problems. According to Storn and
Price (1997), compared to other rival approaches, the main advantages of DE include its fast convergence, the use of a small set of
tuning parameters, its reduced sensitivity to the initial solution
conditions and its robustness. Overall, comparisons on various
benchmark problems show that DE is superior when compared to
other evolutionary algorithms (Sarker et al, 2002; Sarker and Abbass,
2004).
Both algorithms are implemented with a real-valued solution
345
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 346
COMMODITY INVESTING AND TRADING
representation scheme. In particular, each solution is represented by
a real-valued vector x ∈ °N, where N is the number of stocks in the
sample. The largest positive elements of x are used to identify the
stocks comprising the tracking portfolio,3 and after normalisation (to
sum up to 1) they define the corresponding stock weights (w1, …,
wN). The number of units bought from each stock can then be specified as xi = Cwi / PiT. The appendix to this chapter provides a brief
description of the implementations of the two evolutionary methods
used here. The parameters of the algorithms were calibrated after
experimentation in order to achieve a good balance between the
quality of the results and the solution times. The selected parameters
are summarised in Table 13A.1.
BENCHMARK ENERGY INDEX, SPOT AND EQUITY DATA
Because many commodities lack centralised trading, the most reliable spot prices are for those that trade active and liquid futures
contracts, since these are typically used as a pricing benchmark. In
the case of energy commodities, the Nymex is the world’s largest
futures exchange. Initially, a spot price energy index is constructed,
constituting daily prices of the following six energy commodities,
which also trade futures contracts on the Nymex:

The SEI is constructed as an unweighted geometric average of the
individual commodity ratios of current prices to the base period
prices, set at January 31, 2006, until February 1, 2010. The base date
for the SEI is the same date that the equity sample is obtained.
Considering that the boom in commodity index investing is a rela346
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 347
ENERGY INDEX TRACKING
tively new phenomenon, more recent data are utilised to test the
proposed investment strategy. The index’s construction methodology is similar to that of the world-renowned CRB Spot Commodity
Index. The SEI is designed to offer a timely and accurate representation of a long-only investment in energy commodities using a
transparent and disciplined calculation.
Geometric averaging provides a broad-based exposure to the six
energy commodities, since no single commodity dominates the
index. It also helps increase the index diversification by giving even
the smallest commodity within the basket a reasonably significant
weight. Gordon (2006) finds that a geometrically weighted index is
preferred to alternative weighting schemes, because the daily rebalancing allows the index not to become over- or underweighted. This
avoids the risks that other types of indexes are subject to, such as
potential errors in data sources for production, consumption,
liquidity or other errors that could affect the component weights of
the index. Furthermore, through geometric averaging the SEI is
continuously rebalanced, which means that the index constantly
decreases (increases) its exposure to the commodity markets that
gain (decline) in value, thus avoiding the domination of extreme
price movements of individual commodities. As Erb and Harvey
(2006) point out, the indexes that rebalance annually eventually
become trend followers because commodity prices movements
constantly change the weightings, whereas those that rebalance daily
stay closer to the original intent of the index. In addition, Nathan
(2004) shows that the indexes that use geometric rebalancing, and
thus rebalance their weightings daily, generally exhibit lower
volatility.
The mathematical specification used to calculate the geometric
average SEI is the following:
1
" i Pi %n
P1 P 2

SEIt = $! ti ' ! 100 = n t1 ! t2 !…! ti ! 100;i = 1, 2,…,6;n = 6

(13.8)
where, SEIi is the index for any given day, i represents each one of the
six commodities comprising the index, Pti is the price of each
commodity for any given day, and P0i is the price of each commodity
in the base period.
The SEI provides a stable benchmark structure for the index,
making SEI suitable for institutional investment strategies. The
347
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 348
COMMODITY INVESTING AND TRADING
stable composition of the index is an important element, because
when the composition of an index changes over time, the average
return of the index does not equal the return of the average index
constituent, especially when indexes are equally weighted. The latter
makes historical index performance a bad proxy to prospective index
returns, thus distorting the information that investors seek (Erb and
Harvey, 2006). Moreover, it is a better means for evaluating the
movement in energy commodity prices because it is based on spot
prices and not on prices for future delivery that are subject to roll
yields driven by contango and backwardation. The equity data
includes daily prices for stocks picked from the Dow Jones
Composite Average, FTSE 100 and Bovespa Composite indexes. The
equity dataset also includes stocks from a unique pool of energyrelated stocks from the US and UK stock markets. The selection of the
equities included in the two pools is made according to the Industry
Classification Benchmark (ICB) jointly developed by Dow Jones and
the FTSE (see Appendix at the end of this chapter). In the sample
used, the two filtered pools include all stocks from the US and UK
stock markets that are engaged in the various phases of energy
production and processing, listed in the following four sectors: oil
and gas producers; oil equipment, services and distribution; alternative energy; and electricity. After applying the filtering procedure to
the US and UK stock markets, two energy-related stock pools are
constructed, hereafter named US Filter and UK Filter, respectively.
To test the proposed heuristic approach and the efficiency of both
the DE and GA as index-tracking methodologies, five datasets are
selected. All stock prices are closing prices adjusted dividends
according to the annualised dividend yield, and they are all obtained
on a daily basis for the period January 31, 2006 to February 1, 2010
from Thomson Financial Datastream. All stock prices are in US
dollars, thus reflecting the local currency exchange rate against the
US$ at every point in time for the period examined. Should a
company cease trading due to an event (merger, bankruptcy, etc)
within the test period, it is dropped from the sample – that is why the
total number of stocks in the FTSE 100 and Bovespa pools is less than
the total number of stocks included in each index. Moreover, after
adjusting for all US and UK bank holidays, 1,008 observations are
sorted to calculate daily returns for each stock. Considering 252
trading days in a calendar year, the heuristic approach is tested
348
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 349
ENERGY INDEX TRACKING
under various assumptions by selecting the first year as the insample period and the last three years as the out-of-sample period.
The final five datasets have the following number of stocks: N = 41
(UK Filter), N = 53 (Bovespa Composite), N = 65 (Dow Jones
Composite Average), N = 77 (US Filter) and N = 97 (FTSE 100 index).
TRACKING THE SPOT ENERGY INDEX
The performance characteristics of the proposed strategy are examined. The stocks picked by both the DE and the GA are used to track
the performance of the SEI. The initial capital of the investment portfolio is set equal to C = US$100,000, where both the DE and the GA
converge at the end of the in-sample period. In the empirical
analysis, tracking portfolios consisting of maximum K stocks are
used with K = 10, 15 and 20. Three different trade-offs between
tracking error and excess return are also considered, with l = 0.6, 0.8
and 1, thus moving from maximising excess return to minimising
tracking error. The heuristic is then repeated 10 times with the same
set of parameters per run, from which the best solution is chosen.
Figure 13.1 displays the SEI against quarterly rebalanced portfolios selected from the DE and GA, respectively. The portfolios consist
of a maximum of 15 stocks, the FTSE 100, DJIA, Bovespa and UK
Filter and US Filter, respectively; results are shown for l = 1. Looking
at the figures, it is clear that during and towards the end of the recession period, the benchmark index can be best tracked with the
Bovespa baskets, followed by the UK Filter baskets; whereas, during
the last year (2010) it is the US Filter and DJIA baskets that perform
better. The portfolios comprised of optimally selected energy-related
stocks can successfully track the SEI, generating similar returns for
most of the out-of-sample period. The US Filter and UK Filter results
verify that, when energy-related stocks are selected, they can better
replicate the risk and return trade-off of the SEI. The same applies for
the Bovespa baskets, since the Brazilian stock exchange has a large
number of energy- and commodity-related listed companies that
would closely follow any developments in the international energy
markets. In addition, between the DE and GA selected portfolios,
from the graphs it seems that the latter ones can follow more closely
the performance of the SEI, achieving highest excess returns for the
final out-of-sample year.

both the genetic and differential evolution algorithms employed,
under all three rebalancing strategies: buy-and-hold, monthly and
quarterly rebalancing. Using formal statistical evaluation criteria, the
better tracking performance of the UK Filter and US Filter baskets is
also confirmed. In terms of the competing portfolios’ RMSEs, the DE
is more consistent across the various portfolios, whereas the GA
selects portfolios that exhibit larger differences between the worstand best-performing ones. Additionally, in general, GA tends to
select portfolios that have fewer tracking errors and thus track better
350
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 351
ENERGY INDEX TRACKING
the benchmark index when compared to the ones selected from the
DE.
Another interesting observation is that, although the RMSEs are
improved when rebalancing occurs, increasing the frequency from
quarterly to monthly has only a marginal effect. These results are
more profound for the portfolios selected by the DE, and align with
Dunis and Ho (2005), who find that, when comparing alternative
rebalancing frequencies, a quarterly portfolio update is preferable to
monthly, semi-annual or annual reallocations. In terms of their
excess returns, in most cases the portfolios selected by the GA tend to
outperform the ones selected by the DE. The UK Filter and US Filter
baskets, which also have the lowest tracking errors (see panels D and
E on Table 13.1), have excess returns that in some cases are positive,
indicating that the selected portfolios, on average over the out-ofsample period, outperform the SEI.
In the case of the US Filter baskets selected by the GA, the index is
constantly outperformed in terms of excess returns (8.10% for K = 20
and l = 0.6 under monthly rebalancing, and 6.14% for K = 15 and l =
0.6 under quarterly rebalancing); there is only one exception for both
rebalancing frequencies, in which l = 1 and K = 10 when the portfolios underperform the index. This is an indication that the trade-off
criterion does work, and leads to portfolios that compromise any
excess return over a better tracking performance as expressed by the
smaller RMSEs. Thus, taking into account the fact that commodity
indexes performed better compared to the financial indexes over the
three-year out-of-sample period (except the Bovespa Composite),
with the methodology employed the performance of the SEI is
closely replicated, and in the case of the energy-related stock portfolios, the benchmark index is even outperformed.
For Table 13.1, panels A, B, C, D and E report the out-of-sample
daily RMSE and mean daily percentage excess returns, as defined in
equations 13.9 and 13.10, respectively. Under both rebalancing
strategies, the weights of the tracking portfolios are estimated based
on the available data in the rolling window in-sample period (one
year) every month and quarter, respectively. Portfolios’ returns are
adjusted for transaction costs of 0.5% for each transaction.
In terms of the risk–return trade-off (l), it is observed that results
are very similar among portfolios where l = 0.8 and 1. In most cases,
the risk–return trade-off criterion tends to perform well, selecting

portfolios with higher returns and also relatively higher RMSEs.
Moreover, the portfolios selected by the GA tend to be more consistent when the risk–return trade-off rule is applied, compared to the
ones selected by the DE. Overall, when considering both the tracking
performance and the excess returns of the various portfolios, those
with l = 0.8 should be preferred. As far as the criterion regarding the
maximum number of stocks is concerned, in all three rebalancing
scenarios, portfolios with K = 10 tend to perform worst in terms of
RMSEs, but do slightly better in terms of excess returns, for both the
DE and GA selected portfolios. This is also an indication that the
more stocks that are included in the portfolio, the higher the transaction costs when a rebalancing occurs. Overall, it is suggested that
portfolios with a maximum of 15 stocks should be selected, as there
still seems to be a valuable compensation for the additional information and diversification when rebalancing, against the extra
rebalancing costs.
According to the results, for both algorithms, monthly rebalancing
is overall the best option in terms of RMSEs, closely followed by
quarterly rebalancing, whereas when looking at excess returns, quarterly rebalancing appears to improve portfolio performance. The
return of a buy-and-hold portfolio may be higher than that of a rebalanced portfolio when transaction costs are considered, but it is
important to determine the source of the higher return – whether it is
greater capital efficiency as expressed by a higher Sharpe or information ratio, or greater risk. Plaxco and Arnott (2002) showed that
rebalanced portfolios typically have higher Sharpe ratios than buyand-hold portfolios, a finding that suggests that the possible
outperformance of a buy-and-hold portfolio may be the result of
greater risk. Results are more apparent for the GA portfolios, as for
the DE portfolios the difference between monthly and quarterly
rebalancing is only marginal. In the case of the UK Filter basket
picked by the GA, there is an obvious difference in performance
when rebalancing quarterly as opposed to monthly rebalancing. A
more in-depth analysis comparing the portfolios’ information ratios
is presented in the following section. On average, based on the
results from Table 13.1, K = 15 and l = 0.8 is the most desirable
combination providing the best results for most tracking portfolios.
It is, of course, up to the investors’ risk–return appetite to decide
whether rebalancing the portfolio quarterly, which comes with an
354
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 355

extra cost, is better than no rebalancing at all. The same applies
regarding whether l = 0.8 should be used instead of the more risky
trade-off when l = 0.6.
Statistical properties of selected portfolios
Table 13.2 presents some distributional statistics of the selected portfolios’ returns under the quarterly rebalancing scenario.4 Also, in
panel F, the statistics and relevant performance measures for the
following indexes are reported for comparison reasons: two total
return energy commodity indexes – the DJ UBS-Energy and Rogers
Energy Commodity; the three stock indexes from which stocks were
drawn to construct the tracking portfolios – Bovespa, DJIA and FTSE
100; and, finally, the most commonly used benchmark in the finance
industry, the S&P 500. According to the historical annualised volatilities for the out-of-sample period, the SEI is more volatile than the DJ
UBS-Energy and Rogers Energy Commodity Indexes – 48.40% as
compared to 36.21% and 41.11% respectively. The respective
volatility of the equity indexes is in the range of 27–38%. However,
when comparing the information ratios, only the Bovespa index is
able to generate a better risk–return performance compared to the
SEI.
Table 13.2 presents the annualised returns and volatilities of the
tracking portfolios, the skewness and kurtosis, the correlation coefficient between the returns of the benchmark index and the portfolio
that is used each time to replicate this benchmark, and the information ratio under the no rebalancing strategy. Panels A, B, C, D and E
represent the portfolios that include stocks picked each time from the
Dow, FTSE 100, Bovespa, UK Filter and US Filter stock pools. Panel F
presents, for comparison, the relevant performance measures for two
total return energy commodity indexes, the DJ UBS-Energy and
Rogers Energy Commodity; for the three stock indexes from which
stocks were drawn to construct the tracking portfolios, Bovespa,
DJIA and FTSE 100; and the S&P 500.
Moving from no rebalancing to monthly rebalancing, the information ratios tend to go down in all cases, except in the case of the US
Filter baskets for GA, and that of the UK Filter baskets for both DE
and GA. This can be explained by the higher transaction costs, which
have a greater impact on the portfolios’ returns, especially in falling
markets. It can be argued that when rebalancing, the additional

information available from the latest price data does make a difference in reducing the portfolios’ volatility, but the small return
improvement coupled with the rebalancing costs outweighs the
volatility benefits. Results are consistent for all cases for the risk–
return trade-off l. Between monthly and quarterly rebalancing, the
differences are relatively small, but the information ratios are, in
most cases, higher for the quarterly rebalanced portfolios. Under the
buy-and-hold scenario, the best performance in terms of information
ratios is reported for the Bovespa portfolios, and under both monthly
and quarterly rebalancing this is reported for the US Filter portfolios.
In most cases, negative information ratios are reported, indicating
that these portfolios over the out-of-sample period underperform
against the benchmark, as they are associated with the lowest excess
returns.5 This observation can be explained by the fact that energy
markets, as represented by the SEI, have been resistant to the
economic recession, even although they have experienced one of the
most severe up-and-down trends in their history.
The relatively low correlations of the selected equity portfolios
with the SEI (between 9% and 31%) suggest that investors who want
to participate in the energy sector can still benefit from the addition
of the selected baskets. This observation aligns with the findings of
Buyuksahin et al (2010), that the correlation between equity and
commodity returns is not often greater than 30%. Also, correlation is
not the most appropriate performance measure, as it only measures
the degree to which the selected equity baskets and the SEI move in
tandem, and does not capture the magnitude of the returns and their
trajectories over time. Equity returns deviate from a normal distribution, displaying skewness and fat tails. The same is true for the
returns of the SEI that exhibit positive skewness and relatively high
excess kurtosis. Both futures commodity indexes have excess
kurtosis similar to the SEI, with their skewness, however, being
negative. Most equity portfolios selected by both the DE and GA
exhibit negative skewness, indicating that the equity portfolios have
more weight in the left tail of the distribution, in contrast with the
SEI, which has more weight in the right tail.
Finally, as a robustness check, a “naïve” strategy of randomly
selected stocks has been tested, forming equally weighted portfolios
constituted of 10, 15 and 20 stocks. The stocks are selected from the
same five equity pools used by the EAs from a uniform distribution,
358
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 359

thus giving equal probability for all stocks chosen. The evidence
confirms that the strategy and methodology used in this chapter are
much more efficient and stable in achieving a good tracking performance (low RMSEs), and good returns relative to the SEI (positive or
very small negative ERs). Under the “naïve” strategy, there is a large
dispersion of outcomes and no consistency.6
CONCLUSIONS
In this chapter, a geometric average Spot Energy Index is constructed
and then its performance is reproduced with stock portfolios. This is
achieved by investing in small baskets of equities selected from five
stock pools: the Dow Jones, FTSE 100, Bovespa Composite and the
UK and US Filters. The investment methodology used employs two
advanced evolutionary algorithms: the GA and the DE. Both algorithms are self-adaptive stochastic optimisation methods, superior to
other rival approaches when applied to the index-tracking problem.
To test the performance of the tracking baskets, three different rebalancing scenarios were examined, also taking transaction costs into
consideration: buy-and-hold; monthly rebalancing; and quarterly
rebalancing. For comparison reasons, the performance of a “naïve”
investment strategy of randomly selected stocks forming equally
weighted portfolios was also reported.
It was found that energy commodities, as proxied by the SEI, can
have equity-like returns, since they can be effectively tracked with
stock portfolios selected by the investment methodology followed
here. Overall, during the three-year period examined, which reflects
a period before, during and towards the end of the global economic
recession, an investor would realise positive returns by investing in
commodities, as the SEI returns suggest. With the methodology
employed, that performance is closely replicated and, in the case of
the energy-related stock portfolios and those selected from the
Bovespa equity pool, the benchmark index is even outperformed. In
most cases, there seem to be no major differences between the DE
and GA selected portfolios, although the GA tends to select portfolios that have a lower tracking error. Both algorithms mostly do not
utilise the maximum number of stocks allowed to select, with the DE
being more stable in the number of stocks picked between the
various cases of the risk–return trade-off; the GA tends to select portfolios quite different in terms of their composition.
359
13 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:11 Page 360
COMMODITY INVESTING AND TRADING
On average, based on the results presented here, portfolios with 15
stocks and a risk–return trade-off value of 0.8 are the most desirable
combination providing the best results for most tracking portfolios.
Also, it was found that when rebalancing, the additional information
available from the latest price data does make a difference on
reducing the portfolios’ volatility; the resulting return deterioration,
however, outweighs the volatility benefits leading to smaller information ratios. Moving from the buy-and-hold strategy to quarterly
rebalancing and then to the more frequent monthly rebalancing
strategy, returns tend to deteriorate for most selected portfolios, by
both the DE and the GA. Nonetheless, the same holds for the portfolios’ volatilities that also tend to go down when moving from no
rebalancing to the more frequent one. Between monthly and quarterly rebalancing, the differences are relatively small in terms of the
portfolios’ return and volatility performance; however, the information ratios are in almost all cases higher for the quarterly rebalanced
portfolios. The only exception is for the US Filter in the case of the
baskets selected by the GA. Thus, it was concluded that greater
capital efficiency can be achieved with rebalancing, preferably every
quarter, compared to the buy-and-hold strategy.
The investment approach proposed in this chapter for tracking the
performance of the energy sector with stocks selected by two innovative evolutionary algorithms promotes a cost-effective
implementation and true investability. While most mutual funds
cannot invest in commodities directly, they can track the performance of the SEI by investing in the stocks selected by the
evolutionary algorithms used here. There are many investment
houses around the globe that use evolutionary algorithms for tactical
asset management.7 The work and findings presented in this chapter
can encourage asset and fund managers to recognise the importance
of the energy sector and prompt them to set up similar funds that
will track the constructed Spot Energy Index. To that end, the
proposed methodology suggests an effective, and at the same time
least-expensive, way to operate such a fund, giving the full flexibility
of any investment style, long or short, that equities can provide.

APPENDIX
Differential evolution algorithm
DE is a population-based stochastic optimization algorithm that
employs mutation, recombination (crossover) and selection operators to evolve iteratively an initial set (population) of NP randomly
generated N-dimensional solutions. At each iteration (generation),
the algorithm applies the aforementioned evolutionary operators to
each one of the available solutions. In particular, let xiG denote the
solution vector i (i = 1, …, NP) at a generation G, xijG be the jth element
of xiG, and x*G the best solution from generation G (specified
according to the problem’s objective function). Having xiG as the
starting basis, a new solution xiG+1 is constructed replacing xiG in the
next generation G + 1. The solution updating process is performed in
the following three steps:
1.
2.
3.
A mutant solution is constructed by combining xiG with x*G
and two other randomly selected (different) solutions x’ and x’’
from the current generation: vi = xiG + F × (x*G – xiG) + F × (x’ –
x’’). The mutation constant F ∈ (0,2] controls the rate at which
the population evolves.
The parent solution xiG and the mutant vector vi are recombined to produce a crossover solution ui, using the exponential
scheme as shown in Figure 13A.1 (for simplicity the generation
index G is not shown in the figure), where l and j* are randomly
selected from {1, 2, …, N}, such that the part of ui derived from
vi is analogous to a user-defined crossover probability CR (with
higher values corresponding to a stronger impact of vi).
The crossover solution ui is compared against the parent vector
xi,G on the basis of the problem’s objective function f. If f(ui) ≤
f(xiG), then xiG+1 is set equal to ui (ui replaces xi,G in the next
generation); otherwise, xiG+1 is set equal to xiG.
The iterative procedure terminates when a stopping criterion is met
(eg, after a predefined number of generations is explored).
Genetic algorithm
Similarly to the DE algorithm, a GA is also a population-based
stochastic optimisation process. It uses the same evolutionary operators, but implements them in a different way and does not follow the

greedy approach adopted by DE. Starting with an initial (random)
population of solutions, the algorithm proceeds iteratively over a
number of generations. In the GA implemented in this chapter,
the following algorithmic steps are performed at each iteration
(generation).
1.
2.
3.
A pair of parent solutions x and y is selected from the current
population using a tournament selection procedure. Under this
scheme, k individuals (tournament size) are randomly selected
from the population with replacement, and only the best individual (according to the problem’s objective function) is
selected as a parent.
The parent solutions are used to perform the crossover operation with a pre-specified crossover probability (this probability
controls the frequency with which crossover is performed).
Under the arithmetic crossover scheme this operation leads to a
new pair of solutions x’ = rx + (1 – r)y { x’, y’} and y’ = (1 – r)x +
ry, where r is a random number drawn from the uniform distribution in [0, 1].
The crossover solutions are subject to mutation. In this study
the uniform mutation strategy is employed, under which pmN
randomly selected elements of a solution vector are replaced by
random values selected uniformly from a pre-specified range.
The mutation probability pm controls the frequency of the
mutation changes.
The pair of solutions resulting from the mutation operator is placed
in the next generation of solutions, and the above three steps are
repeated until the new population is fully formulated. The procedure ends as soon as a termination criterion is met (eg, the

INDUSTRY CLASSIFICATION BENCHMARK
The ICB is a company classification system developed jointly by
Dow Jones and FTSE. It is used to segregate markets into a number of
sectors within the macroeconomy. The ICB uses a system of 10
industries, partitioned into 19 super sectors, which are further
divided into 41 sectors, which then contain 114 subsectors.
The principal aim of the ICB is to categorise individual companies
into subsectors based primarily on a company’s source of revenue or
where it constitutes the majority of revenue. If a company is equally
divided among several distinct subsectors, the judging panel from
both Dow Jones and FTSE makes a final decision. Firms may appeal
their classification at any time.

The ICB is used globally (although not universally) to divide the
market into increasingly specific categories, allowing investors to
compare industry trends between well-defined subsectors. The ICB
replaced the old classification systems used by Dow Jones and FTSE
on January 3, 2006, and it is still used by the NASDAQ, NYSE and
several other markets around the globe. All ICB sectors are represented on the New York Stock Exchange except Equity Investment
Instruments (8980) and Non-equity Investment Instruments (8990).
Table 13A.2 presents the ICB codes used for filtering all US and
UK stock markets, creating the two energy-related stock pools: the
US Filter and UK Filter, respectively.

Enterprise Risk Management for
Energy and Commodity Physical and
Financial Portfolios
Carlos Blanco
NQuantX LLC and MTG Capital Management
This chapter will present an enterprise risk management (ERM)
framework for energy and commodity physical and financial portfolios based on the three usual building blocks of policies and
governance, methodologies and metrics, and infrastructure.1 The
framework can be used to structure as well as conduct due diligence
on the soundness of the risk-management process for all material
risks – such as market, credit, operational and liquidity risk – as well
as their interactions.
This chapter is divided according to these blocks, with the first
section examining policies and governance, and the need to integrate
risk management in the governance structure of the firm. We then
discuss methodologies and metrics, particularly valuation, risk and
performance metrics for physical and derivatives portfolios, before
moving on to infrastructure, and delving into people, data, operations and systems.
POLICIES AND GOVERNANCE
A “risk governance” framework integrates risk management into the
governance structure of the firm to ensure that risk groups have the
independence, stature and adequate resources to fulfill their responsibilities within the overall business strategy of the firm.
Over the years, many risk management groups that were believed
371
14 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:12 Page 372
COMMODITY INVESTING AND TRADING
to follow “best practices” have been repeatedly unable or unwilling
to prevent their institutions from engaging in excessive risk taking,
which eventually resulted in heavy losses that bankrupted those
firms. Some of the key reasons for this are the assymetric compensation structures at trading desks that encourage excessive short-term
risk taking and the lack of stature of the risk groups compared to the
revenue generating units, as well as the willingness of management
teams and boards to turn a blind eye when profits are rolling in.
Board and senior management teams have the responsibility to
manage the main risks of the firm. However, few board members
have a strong background in financial risk management and few risk
managers have the breadth of skills and experience required to
interact directly with board members and understand or influence
the firm’s strategy and the process that sets the risk appetite and
associated boundaries.
The large exposures accumulated in the real estate and credit
markets at large financial institutions such as Bear Stearns, Lehman
Brothers, Merrill Lynch and AIG before the global financial crisis of
2007–08 caught many boards, senior management teams and risk
groups by surprise. The governance structure in those firms ultimately failed to provide the oversight and early warning signals that
would have prevented firms from taking on too much risk in certain
areas.
In other cases, even although risk managers informed senior
management about the magnitude of the risks taken and the potential catastrophic consequences for their firms, senior-level executives
decided to sugarcoat it for their boards, or omitted critical details.
Lehman Brothers, AIG, Bear Stearns and BP are painful examples of
risk groups’ lack of independence and inability to communicate the
firm’s risk all the way to board level. Another example is BP’s lack of
preparedness and its incompetent response to the oil drilling platform explosion and subsequent oil spill in the Gulf of Mexico in 2008,
which has become a case study on “crisis mismanagement”.
Boards can also ensure that the risk management group roles and
responsibilities are aligned with value creation (or at least the prevention of value “destruction”). Unless the risk management efforts are
structured in the right context, risk management activities will take a
secondary role, and may ultimately end up destroying value and
negatively interfering with the business strategy of the firm.

An example of best practices in the integration of risk management within the overall governance structure is the risk management
policy of BHP Billiton PLC, one of the largest diversified resources
companies in the world (see Panel 14.1).
PANEL 14.1: BHP BILLITON RISK MANAGEMENT POLICY2
BHP Billiton’s risk management policy (see below) defines the group’s
approach to risk management, linkage to the corporate objective and integration into its business processes.
❏ “Risk is inherent in our business. The identification and management
of risk is central to delivering on the corporate objective.
❏ Risk will manifest itself in many forms and has the potential to impact

By understanding and managing risk we provide greater certainty and
confidence for our shareholders, employees, customers and
suppliers, and for the communities in which we operate.
Successful risk management can be a source of competitive
advantage.
Risks faced by the Group shall be managed on an enterprise-wide
basis. The natural diversification in the Group’s portfolio of
commodities, geographies, currencies, assets and liabilities is a key
element in our risk management approach.
We will use our risk management capabilities to maximise the value
from our assets, projects and other business opportunities and to
assist us in encouraging enterprise and innovation.
Risk management will be embedded into our critical business activities, functions and processes. Risk understanding and our tolerance
for risk will be key considerations in our decision-making.
Risk issues will be identified, analysed and ranked in a consistent
manner. Common systems and methodologies will be used.
Risk controls will be designed and implemented to reasonably assure
the achievement of our corporate objective.
The effectiveness of these controls will be systematically reviewed
and, where necessary, improved.
Risk management performance will be monitored, reviewed and
reported. Oversight of the effectiveness of our risk management
processes will provide assurance to executive management, the
board and shareholders.
The effective management of risk is vital to the continued growth and
success of our Group.”

COMMODITY INVESTING AND TRADING
Any investment and trading operation should clearly articulate
and communicate the core investment strategies and the firm’s risk
tolerance. Written policies can establish the link between its business
strategy and its tolerance for risk.
A final component of the policy dimension is the existence of clear
lines of authority and an appropriate level of risk disclosure, which
makes the risk transparent to internal and external stakeholders. The
degree of authority and independence of the risk group is a function
of the relative stature of the group within the firm. For example, a
risk group that reports directly to the heads of the business unit in
charge of revenue generation is unlikely to have the independence
and authority to prevent excessive risk taking.
It is important not to confuse detailed investment strategy and
position-level disclosures (often considered highly proprietary by
portfolio managers) with risk disclosures designed to provide assurances that the risk levels are within the parameters expected by
investors. For example, an investment manager that provides valueat-risk (VaR) disclosures to investors is not giving away proprietary
information that could be used by counterparties against the firm’s
portfolio.
VALUATION AND RISK METHODOLOGIES AND METRICS
The second building block of the risk process consists of the methodologies and metrics used to measure and manage risk, as well as their
integration in risk-adjusted performance measures.
Given the continued high volatility and extreme moves in the
energy and financial markets, one of the main contributions of the
risk groups is the calculation of key risk metrics that can assist
decision-makers with the process of identifying, measuring and
managing the firm’s material risks.
Since the first generation financial risk models were published in
the mid-1990s, there have been significant developments in the
modelling of market, credit, liquidity and operational risk of energy
and commodity portfolios. However, the excitement and quick
progress of the “early years” has now gone, and change tends to be
slower and incremental and driven by regulatory and external pressures.

calculations involve modelling costs and revenues related to the
operation of physical assets (for example, generation, storage), spot
purchases and sales in the spot market, as well as profit and losses
from the hedging and trading portfolio.
The process for calculating CFaR and EaR requires careful
analysis and understanding of each portfolio’s material risks. For
example, volume-related variability embedded in many physical
and derivative contracts and operations-related constraints – such as
ramp-up and ramp-down rates and plant outages – need to be
explicitly accounted for to obtain a realistic value and risk estimates.
The same is true for critical operating constraints from assets and the
material clauses in contracts, as well as the limitations of physical
and financial arbitrage strategies such as market liquidity and available hedging instruments. Figure 14.1 shows some of the
components required to compute CFaR and EaR.
Failure to incorporate material risks when evaluating a hedging or
trading strategy such as CFaR and collateral implications may have
unintended consequences and expose the firm to unwanted risks.

ENTERPRISE RISK MANAGEMENT FOR ENERGY AND COMMODITY PORTFOLIOS
When energy and commodity prices collapsed in the summer of
2008, many firms experienced a large volume of collateral calls that
forced them to go to the capital markets to raise extra capital at a time
when banks were not extending credit to their counterparties. Firms
without contingency plans in place that had funding problems
ended up having to pay exorbitant borrowing costs or were just
unable to continue funding their hedges. For example, airlines that
had hedging programmes in place at the time accumulated large
mark-to-market losses in their hedge portfolios when crude oil and
jet fuel prices fell over 50% in just a few months in 2008. In addition,
the global financial crisis caused a sharp drop in business travel
worldwide that impacted their operating revenues. Rating agencies
downgraded many airlines due to the worsening liquidity picture
caused by the combination of lower forecasted revenues and the
large cash outflows due to collateral calls from their existing hedges.
As a result, hedging costs increased considerably at a time when
financial institutions were attempting to reduce their credit risk
exposures. The response by many airlines was to discontinue or
reduce the size of their hedging programmes.
Forward-looking key risk indicators such as CaR can measure the
maximum collateral outflows for a given confidence level, taking
into account initial and variation margin requirements for over-thecounter (OTC)-cleared and exchange-traded contracts, as well as the
material margin clauses such as the credit support terms for OTC
transactions (eg, thresholds, independent amounts, downgrade triggers, eligible collateral).
Figure 14.2 shows the potential future collateral outflows for a
derivatives portfolio, as well as the potential counterparty future
exposures as a function of simulated market environments. Both
metrics in Figure 14.2 are calculated for a 95% confidence level and
provide an indication of the potential magnitude of unsecured credit
exposures and potential margin payments.
Stress tests
In order to manage extreme event risk, the risk process should also
include stress tests that question the model assumptions and also the
“market consensus view” at any given moment. Stress tests are
particularly relevant in markets that experience large sudden fluctuations as well as regime changes, and the results from the analysis

can provide key insights to portfolio managers to develop contingency plans.
Stress test committees that have representatives from the main
groups in the firm – such as fund managers, risk managers and
analysts – can proactively identify scenarios that would prove useful
preludes to market crisis and feed that information into strategic
planning, capital allocation, hedging and other major decisions.
If stress test results (as illustrated in Figure 14.3) indicate that the
hedge fund’s losses are beyond their tolerance level or the available
capital, then immediate instructions could be sent to the fund
managers to reduce the exposure to such event or increase its capital.
Another area where stress tests are critical is liquidity risk
management and capital adequacy. Liquidity risk management is
often mistaken for “crisis management”, as lack of planning often
forces companies to address liquidity risk management issues only

COMMODITY INVESTING AND TRADING
when crises occur. In order to estimate liquidity risk, companies
need a framework that explicitly addresses the potential demand
and supply of cash. This framework should address medium- and
long-term horizons as well as the cost of liquidating positions in a
stressed market environment.
Risk managers can use scenario analysis and reverse stress tests to
identify scenarios that could result in liquidity shortfalls, particularly
under stress market conditions. Funding liquidity risk measurement
requires metrics such as CFaR, CaR and margin-at-risk, which identify potential margin and collateral calls in stress situations.
The most sophisticated risk and stress test models incorporate
more realistic assumptions about market dynamics, particularly in
properly modelling the tails of the distribution, including a dynamic
approach to correlation to allow firms to incorporate credit and
liquidity considerations, and finally a method to anticipate the risk
taker’s response to various market events. A set of principles to
measure and manage tail risk is presented in Panel 14.2.
Backtesting
Backtesting a risk model consists of evaluating whether the risk
model forecasts are adequately capturing the magnitude and
frequency of profit and losses (P&Ls). There is a wide range of quantitative and qualitative backtests,3 but most individual tests have low
statistical significance. As a result, the most common way to perform
backtesting is by analysing a chart with P&L series and VaR forecasts. The backtest procedure consists of comparing the daily VaR
with the subsequent P&L for T+1 as the VaR forecast attempts to
determine the magnitude of future P&L.
The most common VaR backtests analyse whether the number
and magnitude of “exceptions” is within the VaR model predictions.
Loss exceptions are those losses greater than the prior day VaR,
while gain exceptions are gain larger than the prior day VaR on the
positive tail of the distribution (VaR+). Many firms exclusively focus
on loss exceptions and ignore gain exceptions, but that may lead to
situations where large gains could go unexplained for long periods
of time and eventually turn into large unexpected losses.
An additional test consists of checking whether those exceptions
are autocorrelated, which would result in many exceptions taking
place during short periods of time that potentially could result in

ENTERPRISE RISK MANAGEMENT FOR ENERGY AND COMMODITY PORTFOLIOS
PANEL 14.2: TAIL RISK MANAGEMENT PRINCIPLES
Risk management is ultimately the art of managing risk based on the presence of imperfect (and constantly evolving) information. Measuring and
managing risks in the tail of the distribution is both an art and a science. A
few basic risk management principles for extreme events will now be
examined.
Include all plausible scenarios of material risk factors in the analysis
Stress scenarios should integrate all material risk factors, such as market
risks (eg, price, basis, volatility), counterparty risks, and also relevant
funding and market liquidity risks in a coherent fashion. Ignoring key risks
may result in risk information offering a simplistic and inaccurate view of
tail risk that can give a false sense of security.
Choose appropriate tail risk metrics and modelling horizons
The most common risk metrics used, such as VaR and standard deviation,
fail to capture the dynamics of the tail of the distribution of potential
outcomes. Fortunately, there are other metrics, such as stress test results,
expected tail loss (ETL) and expected shortfall (ES), spectral risk measures
and probable maximum loss (PML), that can complement a risk limit
structure (see Chapter 2 of Dowd, 2005).
Measurement is just the starting point
Adequate preparation for any future crises requires forward-looking and
creative thinking, as well as carefully designed contingency plans.
Designing and conducting realistic stress tests that provide insights into
the likely portfolio gains and losses under particular extreme events is
necessary but not sufficient. The development of contingency plans to
respond to those hypothetical extreme events have lagged behind as most
firms have been shown to be ill-prepared to respond to crises.
Expect the unexpected: Account for model risk
While crises in financial, credit and energy markets often share some similarities with prior ones, each new crisis has differentiating elements that
tend to catch most players by surprise. The lesson is that any contingency
plan against extreme events should leave a significant buffer to account for
variations from expected extreme scenarios.
cumulative losses or gains considerably higher than the risk model
forecasts. As a general rule, any exceptions should be investigated by
the market risk management group, and the reasons for the exception should be recorded to identify regular “culprits” and corrective
action taken if necessary. If the backtests show that the risk models
381
14 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:12 Page 382
COMMODITY INVESTING AND TRADING
ultimately failed to capture actual P&L variability, they should be
replaced as the primary market risk control tool.
Valuation models for physical assets, contracts and financial
derivatives
Energy and commodity markets are dominated by asset-based
traders that optimise their strategies around physical assets such as
storage facilities, pipelines and power plants. The traders and operators of those assets attempt to maximise risk-adjusted profits based
on observable market spreads and the specific asset operating
constraints. The valuation, risk metrics and hedging ratios calculated
from a static model are not just likely to be inaccurate, but could lead
to suboptimal decisions that would impact the profitability.
In order to capture the multiple risk dimensions involved in
hedging and trading, a dynamic simulation framework with three
critical components is needed: the ability to handle multiple risk
factors (eg, price risk, credit events, operational issues), multiple
instruments (eg, physical contracts, derivatives) and the ability to
capture events taking place at multiple steps in time.
Dynamic risk simulation involves modelling the variability of one
or more metrics (eg, cash flow, earnings, mark-to-market, liquidity)
based on a realistic evolution of a set of key state variables, as well as
the firm’s response to those changes (eg, operating, hedging and
trading strategies). The analysis consists on “leaping forward” in
time by simulating risk variables at various point in time in the
future and evaluating a series of value and risk metrics (eg, costs,
revenues, profits, VaR) under each of those scenarios.
An added benefit of using dynamic simulation-based risk tools is
the potential for risk management to play a larger role in strategic
business decisions at various levels of the firm. For example, simulation analysis can assist trading and operating groups in developing
asset optimisation and hedging strategies based on the evaluation of
risk–return trade-offs. It can also help finance groups creating
forward-looking earnings projections by ensuring they are consistent with the risk appetite of the firm. Another critical area is the
evaluation of important investment and divestment decisions from a
marginal and stand-alone risk point of view.
Advances in financial engineering and computational finance
such as least squares Monte Carlo and dynamic programming have
382
14 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:12 Page 383
ENTERPRISE RISK MANAGEMENT FOR ENERGY AND COMMODITY PORTFOLIOS
allowed for the widespread use of dynamic risk simulation solutions
in energy firms.
Risk-adjusted performance measurement
Identifying, measuring, managing and pricing risk involves
designing appropriate policies and systems so different business
units and risk-taking activities can be evaluated with a risk-adjusted
return in mind. The practical requirements to implement such
changes involve modifying performance measurement mechanisms
to integrate the risk and return numbers in the bonus allocation
process, as well as changing the risk systems, to allow for risk
numbers calculations at the risk-taking unit level.
Risk-adjusted return on capital (RAROC) measures, which are
widely used in the financial services industry, provide a common
measurement unit for risk-adjusted returns on allocated (ex ante) and
utilised (ex post) risk capital.
A RAROC system can assist managers to determine the most efficient generators of revenue on a risk-adjusted basis, as well as set the
threshold returns given the risk assumed to generate them. Let us
assume that we are the trading manager of a commodity trading
desk and have two traders. Both of them made a profit of US$10
million, but on average one of the traders used 80% less risk capital
than the other. If the trading manager only considers the size of the
gains, both should get a similar bonus. However, from a riskadjusted perspective, the trader that took less risk should receive a
higher bonus.
An investment evaluation process based on economic capital
considerations, where decisions are based on a risk-adjusted return
basis, encourages corporate managers to become risk managers
because they must take risk into consideration when allocating
resources internally and making investment and divestment decisions. Determining the economic capital allocated to each activity or
business unit provides senior management with a mechanism to link
risk and return, and therefore provide a risk–reward signal that can
be used at different levels of the firm.
INFRASTRUCTURE
The third building block is the risk infrastructure. The infrastructure
subcomponents are: people, systems, data and operations.
383
14 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:12 Page 384
COMMODITY INVESTING AND TRADING
Risk management functions have too often been built around
quantitative risk managers who lacked market experience and requisite managerial skills. A chief risk officer (CRO) with the right skills,
experience, independence and courage to perform the job is a critical
component in the risk management organisation. The CRO’s effectiveness is a direct function of the power and independence granted
that position, the quality of the people in the risk organisation, the
associated culture, and incentives and experience. If we were to boil
down empowerment to one question, then we might ask an organisation if its CRO is empowered to be proactive, as opposed to
remaining reactive.
The budget of the overall risk management function determines
the scope and depth of activities that can be performed. The education and experience of the risk management personnel is a direct
reflection of an organisation’s ability to hire and retain first-class risk
managers. The stature of risk managers is also important; if risk
management personnel do not have the stature to be able to stand up
for their beliefs under pressure, it is a recipe for eventual failure.
Risk groups must balance the day-to-day “tactical” issues such as
risk measurement, reporting and limit checking with the more
strategic aspects of evaluating business decisions that have a material impact on the firm’s risk profile and whose effect may only be felt
further into the future.
Risk management systems and data
Financial risk management and technology advances have made
possible the integration of data from multiple sources in order to
provide the firmwide perspective required to forecast risk scenarios
involving multiple risk dimensions.
However, many energy trading and risk systems have failed to
keep up to date with the advances in risk analytics. Those systems
excel at performing tasks such as scheduling, nomination or
accounting of physical and financial trades, but offer limited risk
functionality and lag behind in their ability to perform sophisticated
risk analysis.
Many of the pioneering risk software firms that greatly
contributed to important methodological advances in energy risk
modelling are now part of larger software and consulting firms.
Experience has painfully shown that their ability to innovate beyond

PANEL 14.3: RISK MANAGEMENT LESSONS FROM OSPRAIE
CAPITAL MANAGEMENT4
Ospraie Management LLC, one of the largest commodity trading funds in
the world, was forced to liquidate its largest fund after losing 38.6% in the
first three quarters of 2008.
The investment firm was run by Dwight Anderson, an experienced
commodities trader with an excellent trade record up to that point. In a
letter to investors after closing the fund, Anderson wrote that, “I am
extremely disappointed with this result and the fund’s sudden reversal in
performance. After nine years of striving to be a good steward of your
capital, I am very sorry for this outcome.”
Just a few months before closing the fund because of the large losses,
Anderson told Bloomberg “We do everything that we can to manage the
risk, and I think we’re better at it today than we were a year ago.”
The sudden reversal in the fund’s performance caught most investors by
surprise. For example, in 2007 the head of Credit Suisse’s New York-based
alternative investments group, which managed US$134 billion in private
equity and hedge fund assets, said that “Anderson’s the best-in-class
player in dealing in the world of basic industries and commodities”.
pure technology and computational solutions has come to a near
halt. For example, most valuation and risk models are still based on
static portfolios over short time periods that ignore material risks
such as volumetric and operational risks. In addition, most models
used by risk practitioners still assume that market changes are
lognormal, which fail to account for key characteristics of energy and
commodity prices such as mean reversion and jumps.5
One of the major gaps that exists in the risk management process
at many firms is the lack of effective communication between risk
groups and the senior management team. A poorly informed
management exposes the organisation to risk “blind spots”.
Some risk managers have taken a proactive role, and regularly
identify those key risk information gaps (see Table 14.3) and continually develop and improve the tools to breach them.
SUMMARY AND CONCLUSIONS
Energy and commodity markets are some of the most volatile
markets in the world, and firms operating in those markets should
approach risk management with caution.
Firms that implement a rigorous enterprise risk management

Credit Valuation Adjustment (CVA) for
Energy and Commodity Derivatives
Carlos Blanco and Michael Pierce
NQuantX LLC and MTG Capital Management; NQuantX LLC
Traditionally, counterparty and liquidity risks have been largely
ignored in the valuation and risk measurement of energy and
commodity portfolios. The main reasons for this were the lack of
commonly accepted methodologies to measure and price those risks,
as well as the general perception that they were relatively immaterial. However, large credit losses and funding liquidity problems,
significant advances in credit risk measurement technology and
changes in accounting standards and regulations such as the Dodd–
Frank Act have led to an increased focus on improving counterparty
and liquidity risk management practices.
At the centre of the credit revolution is the concept of credit valuation adjustment (CVA), which likely to play as great a role for credit
risk management as value-at-risk (VaR) did for the practice of
market risk management. In this chapter, we will examine the
concept of CVA and show how to calculate CVA at the trade and
portfolio levels. We will also discuss the allocation of portfolio CVA
and active credit risk management with CVA desks, as well as how
to set up a system of credit risk charges.
CVA IN A NUTSHELL
In simple terms, CVA is the price of credit risk for a deal or portfolio
with a given counterparty. When two entities enter into a derivative
transaction, they also exchange an implicit option to default.

15 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:38 Page 390
COMMODITY INVESTING AND TRADING
From a valuation perspective, the fair value measurements of
derivative contracts should include a risk adjustment reflecting the
amount market participants would demand because of the credit
risk in the future cashflows that will be exchanged through the life of
the contract. The fair value of the embedded default option that
could result in a credit loss is the CVA.
Calculating CVA requires estimating the difference between the
mark-to-market discounting expected cashflows using the risk-free
rate and the credit-adjusted mark-to-market, which consists of incorporating the credit risk of the transaction into the mark-to-market
calculations.
CVA = Mark-to-market (risk-free) – Mark-to-market (credit-adjusted)
CVA and debt valuation adjustment
CVA can be unilateral or bilateral, depending on whether the adjustments are based on one or two of the parties in the deal. In unilateral
adjustments, the entity performing the CVA calculations only
discounts the derivatives assets (eg, in the money transactions) using
the credit-adjusted curves of the counterparties, while no adjustments are made for liabilities (out-of-the-money transactions). In
addition, the entity performing the calculations could also perform a
similar adjustment for its liabilities, but using its own credit riskadjusted curves. These adjustments are also known as the debt
valuation adjustment (DVA).
In bilateral adjustments, the entity performing the calculations
takes into account the effect of the counterparty’s credit risk in determining the prices they would receive to transfer an asset, as well as
the effect of the entity’s credit risk in determining the prices they
would pay to settle that liability. The main differences between bilateral and unilateral CVA calculations is that the former integrates the
credit risk from the two parties in the transaction, and therefore is
calculated as the net difference between the unilateral CVA and the
DVA.
Another risk adjustment is the funding valuation adjustment
(FVA), which incorporates funding costs for the position – such as
initial and variation margin, and collateral.

Credit-adjusted rate curves
In order to calculate CVA, one of the critical set of inputs is the creditadjusted curves for the parties in the deal, which reflect the rates at
which each counterparty is able to borrow money for different maturities in the capital markets.
There are several alternatives for creating credit-adjusted curves,
such as using credit default swap (CDS) spreads, corporate bond
yield spreads, and default probabilities from rating agencies, hybrid
models and internal rating systems. Table 15.1 provides a summary
of the alternative inputs.

CVA methods
There are several ways of calculating CVA, but we can group the
various methods in three categories. The first is the discount rate
adjustment, which requires the use of credit risk-adjusted discount
curves to calculate fair values. A common way of creating the credit
risk-adjusted curves for a given counterparty is by adding the CDS
spread to the risk-free rate curves used for present value calculations.
Figure 15.3 shows the CDS spreads for various North American
firms, as well as the zero-coupon risk-free curve and the riskadjusted curves. The risk-free rate curve is the US dollar zero coupon
curve for September 3, 2012. The credit-adjusted curves for each
entity in Figure 15.3 are created by adding the CDS spread to the
zero-coupon rate for each maturity.

The discount rate adjustment is the most widely used method for
fair value reporting due to its simplicity. One of the main shortcomings is that the credit exposure is assumed to be static, and therefore
the CVA is not dependent on the volatility of the mark-to-market
(MtM) of the deal, making it more likely to underestimate the credit
risk of the instrument.
The second type is known as the exponential CDS default method,
and requires the estimation of probabilities of default and recovery
rates. We can approximate the probability of default from quoted
CDS spreads for a given term by applying the following formula:
! CDSSpread t ( years) $
PD = 1! e #
!
&
10000 %
" (1! R )
where:
❏ PD is the probability of default;
❏ CDS Spread is the credit spread in basis points;
393
15 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:38 Page 394
COMMODITY INVESTING AND TRADING
❏ T (years) is the maturity of the CDS measured in years; and
❏ R is the recovery rate (a common assumption made in published
CDS spreads is that the recovery rate is 40%).
Once the probabilities of default and recovery rates are estimated,
we can calculate the CVA for the deal based on the fair value using
the risk-free rate multiplied by the probability of default and the loss
given default (LGD), which is 1 less the recovery rate.
CVA = MtM(risk free) × PD × (1 – R)
Again, the credit exposure is assumed to be static with this method,
so potential future exposures will tend to be underestimated.
The third method for calculating CVA is the exposure-based
approach, which requires an estimation of expected exposures (both
positive and negative) over the life of the deal, default probabilities
and recovery rates at different time steps. Exposure-based methods
combine market and credit risk elements.
In exposure-based methods, in addition to the forward curves and
other market variables, CVA is a function of the volatility of market
prices over time, the timing of cash inflows and outflows, the existence of collateral and netting agreements, the term structures of
default probabilities, as well as the expected recovery values.
Expected future positive and negative exposures can be calculated
using closed-form solutions or simulation methods.
Following Stein (2012), CVA is calculated as:
T
CVA = (1! R ) ! 0 S (t ) P (t ) dt
where S(t) is the expected exposure of the deal at time t, and P(t) is
the default probability time function.
As an alternative to calculating the full integral, we can divide the
–
time interval [0,T] into periods [ti, ti+1] and select ti ∈ [ti, ti+1].
A common choice for the time unit in each time interval is the
average between the two points:
T
T
CVA = (1! R ) ! 0 S (t) P (t )dt " (1# R ) ! S ( ti )P (ti )
t=0
where
P (ti ) =

P (t ) dt
15 Chapter CIT_Commodity Investing and Trading 26/09/2013 12:38 Page 395
CREDIT VALUATION ADJUSTMENT (CVA) FOR ENERGY AND COMMODITY DERIVATIVES
is the probability of default in the interval [ti, ti+1].
If we simplify to just one period, CVA and DVA for a one-period
horizon can be calculated applying the following formula:
CVA = PDcpty × EPE × LGDcpty ≈ Spreadcpty × EPE
DVA = PDown × ENE × LGDown ≈ Spreadown × ENE
where PD is probability of default, EPE and ENE are the expected
positive and negative exposures, respectively.
We can see the expected positive exposure (EPE) and the expected
negative exposure (ENE) profile for a set of nettable contracts with a
given counterparty in Figure 15.4. The EPE is used for CVA calculations and represents the expected exposure in the event of default by
our counterparty at different horizons. The ENE represents the
expected exposure in the event of our own firm defaulting.
Exposure-based methods are the more comprehensive ones, as
they overcome the shortcomings of assuming that the credit exposure is static. The three main methods are summarised in Table 15.2.

CVA at the counterparty level
To perform the credit adjustment to the value of a derivatives book,
we need to calculate the CVA and DVA for each counterparty in the
book. The net adjustment is the difference between the sum of the
CVA minus the sum of the DVA for all counterparties.
The calculation of the CVA and DVA for each counterparty is not
simply the sum of the individual trades CVA and DVA. This is
because, in order to calculate CVA at a portfolio level, it is necessary
to take into account netting, collateral and other credit risk mitigants.
We can use any of the CVA methods to perform calculations at the
portfolio level. The main difference is that, instead of just adding the
individual MtM and potential exposures of each instrument, we
need to perform those calculations after taking into account any
credit mitigants. For example, if we use the discount rate method, we
could calculate the net exposure for each counterparty after applying
netting and collateral rules, and then calculate CVA by multiplying
the net exposure times the credit spread.
For portfolio level calculations, it is common to perform simulation of risk exposures at the counterparty level for multiple scenarios
after taking netting and collateral into account. The steps involved in
calculating portfolio CVA in a simulation framework are shown in
Figure 15.5.
Although CVA calculations are based on EPE and ENE, credit risk
charges are often based on potential future exposures at a high confidence level. Figure 15.6 shows a potential future exposure (PFE)

From portfolio CVA to deal CVA
When two entities enter into a series of transactions, they also
exchange an implicit option to default. CVA is the price or cost of
credit risk for a deal or portfolio with a given counterparty.
CVA can be calculated at the individual transaction or at each
counterparty portfolio level. The overall CVA for the exposures with
a given counterparty is not simply the sum of the individual deal
CVA, because of the need to take into account credit risk mitigation
rules that apply to those exposures. For example, a trading entity
may have several deals with the same counterparty that have large
stand-alone CVAs, but if those exposures offset each other and there
are netting agreements in place, the overall portfolio CVA will be
considerably lower than the sum of the individual CVAs.
Despite the non-additive nature of portfolio CVA, it is possible to

allocate it among the various portfolio constituents in a similar
fashion than we can calculate marginal VaR for individual portfolio
components to determine the contribution to diversified VaR of a
given trade or strategy. The allocation of the portfolio CVA into each
individual trade is important for individual hedge accounting designations, as well as improving the understanding of the marginal
impact of individual trades on the overall CVA.
The process to allocate portfolio CVA into individual components
consists of determining the marginal contribution of each trade to the
portfolio CVA. The marginal contribution of a given trade could be
positive, negative or neutral, depending on the change in the portfolio CVA before and after including that trade.
CVA allocation approaches
There are various approaches to allocating CVA among individual
portfolio constituents. It is important to understand the differences
between them because the choice of allocation method may have
material implications on how credit risk adjustments of assets and
liabilities are reported, as well as hedge effectiveness tests and qualitative derivatives disclosures.
The most common CVA allocation methods are:1
❏ In-exchange or full credit: the stand-alone CVA for each derivative instrument is directly applied. There is no need to calculate
portfolio CVA or apply any allocation methodologies.
❏ Relative fair value: the portfolio CVA is allocated to each derivative instrument according to the sign and magnitude of the fair
value of each derivative asset and liability.
❏ Relative credit adjustment: the portfolio CVA is allocated to each
derivative instrument according to the sign and magnitude of
the stand-alone CVA for each derivative asset and liability.
❏ Marginal contribution: the portfolio CVA is allocated to each
derivative instrument based on the sign and magnitude of the
marginal contribution to CVA of each individual derivative asset
and liability.
A numerical example of the application of the relative creditadjustment method is shown in Tables 15.4, 15.5 and 15.6; note that
the application of this method in particular is investigated because

the relative credit adjustment method is relatively easy to implement, and superior to the in-exchange or full credit, and the relative
fair value methods.
The first step involves calculating the stand-alone CVA for each
individual trade. If we add the stand-alone CVAs at the trade level,
we can calculate the “undiversified” portfolio CVA assuming that
the portfolio consists of non-nettable, non-collateralised trades, effectively ignoring credit-mitigation effects. The magnitude and sign of
each stand-alone CVA determines the relative weights for the deals
that are part of that counterparty’s portfolio. Table 15.5 shows the
deal-level breakdown of MtM and CVA of the portfolio with trades
made with EDF Trading as the counterparty. The bottom row shows
the portfolio MtM, the “undiversified” CVA as a sum of stand-alone
CVA, as well as the credit-adjusted MtM. The relative percentage
weights are calculated by dividing each individual CVA by the undiversified portfolio CVA.

The next step consists of calculating the portfolio CVA based on
the unsecured exposure with each counterparty, which is estimated
after taking into account any relevant netting and credit-mitigation
tools. Portfolio CVA calculations can be made using current or
expected exposure methods for the various trades in the portfolio.
The combined MtM exposure, the net exposure and the portfolio
CVA are shown in Table 15.5. In our example, as the current exposure is largely collateralised, the portfolio CVA is substantially lower
than the sum of the stand-alone CVAs. The last column shows the
combined credit-adjusted MtM for the exposures with BP Trading.
As a final step, we can calculate the portfolio CVA portion that
will be allocated to each individual deal by multiplying the relative
weights calculated in Table 15.4 times the portfolio CVA. This is
shown in Table 15.6.
A comparative analysis of the different CVA allocation methodologies is shown in Table 15.7. The relative credit adjustment and the
marginal contribution approaches are the most accurate ones, but
require the calculation of new metrics such as stand-alone and
marginal CVAs. Under those approaches, the CVA of a portfolio of
trades with a given counterparty is allocated among its individual
constituents according to the relative weight of each individual
stand-alone or marginal CVA.
The state of the practice of CVA reporting by energy trading firms
is still in its infancy. Several publicly traded entities still do not calculate portfolio CVA and most do not allocate portfolio CVA into

individual deals. The main reason given is that the allocation of
credit risk would not materially impact the fair value or the determination of the hedge effectiveness of a hedging relationship.
Credit limits, charges and CVA desks
Traditionally, credit risk management at energy and commodity
trading firms has been a passive exercise, where credit risk managers
set and monitor exposure limits and traders can continue dealing
with a given counterparty as long as those limits are not breached.
Those limits are often defined based on the current exposure at the
counterparty level, which is generally calculated by taking the markto-market value of open positions, adding account receivables and
accounts payable, and open settlements and applying appropriate
netting rules and credit risk mitigation tools. In addition, the limits
may be scaled as a function of the evolution of the creditworthiness
of the counterparty. A sample credit report is shown in Table 15.8
with limits based on current exposures as a function of the counterparty’s internal rating.

limits is that it creates a situation where traders become the frontline
credit risk managers for the firm while their goals become that of
maximising profitability, not managing that risk. As a result, the firm
may end up with excessive credit risk concentrations to a given
industry, geographical region or tenor due to the combined trader
exposures. These concentrations could be exacerbated in the future if
the exposures are driven by the same market risk factors.
To complement static current exposure limits, many credit risk
departments have also added, as part of the limit structure, forwardlooking exposure and risk metrics such as maximum PFE at a given
confidence interval. Those metrics can alert credit risk managers of
the exposures that may grow beyond the maximum thresholds as a
result of market fluctuations. In the last column of Table 15.8, we can
see that the existing exposures with Barclays, Morgan Stanley, J.
Aron and Southern Company may exceed the credit limits in the
future, even although they are within the approved current exposure
limits.
The next level in sophistication of the credit risk function involves
designing a system of credit risk charges that can ensure that risk
takers become actively involved in the risk management process. A
system of credit risk charges and reserves can assist the front office in
setting the right price for each new transaction based on the risks
incurred by the firm, and also to create a fund with reserves to
protect the firm against future credit losses.
There are two main types of counterparty risk charge systems. The
first is based on setting upfront charges for each new deal as a function of the potential credit losses over the life of the deal using CVA

or PFE metrics.2 Traders often strongly oppose these types of
systems due to the fact that charges for the full life of the deal are
applied upfront, and if the deal is reversed before maturity that
would result in overcharges.
The other type is known as pay-as-you-go, and consists of
applying a daily credit risk charge based on current unsecured credit
exposures.3 Pay-as-you-go systems are relatively easy to implement
as the only metrics required are the unsecured credit exposure
against each counterparty and the daily cost of capital of that
counterparty.
Pay-as-you-go systems are conceptually appealing for many
trading organisations, but the success of the implementation of the
credit risk charge system is often dependent on the details. For
example, if traders are charged on the stand-alone credit risk of each
deal, they are likely to be overcharged on an overall basis and therefore be at a competitive disadvantage over other firms.
The best systems strike the right balance in terms of taking into
account diversification benefits at the counterparty portfolio level
and also impact the behaviour of the risk takers directly. Although
pay-as-you-go systems apply daily charges, the credit risk managers
can provide traders with the distribution of their maximum potential
future credit charges before they conduct a new deal group using
forward-looking probability-based credit metrics such as PFE.

Active risk management with CVA desks
As a response to the increased magnitude and complexity of the
credit risk dimension in derivatives trading, many firms have
created internal groups, known as CVA desks, with a mandate to
measure, price and manage counterparty risks. CVA desks act as
specialised units that manage the credit risk of the consolidated
exposures with each major counterparty.
Some CVA desks are in charge of implementing the system of
credit charges and reserves for the firm. A sample decision flow
diagram is shown in Figure 15.7. When a trader wants to conduct a
new deal, the CVA desk determines the cost to protect the credit risk
of that new deal and communicates it to the trader. The credit charge
can be calculated based on the size, liquidity and duration of the
exposure, the credit risk mitigation tools in place (netting, collateral,
guarantees, etc), as well as the creditworthiness of the counterparty.
If the trader decides to go ahead with the transaction, it may pass the
fees to the counterparties by pricing the deal taking into account the
cost of protection.
The CVA desk can also play an active role by encouraging traders
to use collateral to minimise credit exposures, and also to trade with
certain counterparties that reduce overall portfolio exposures. In
order to do so, they need to have the ability to calculate credit risk on

an aggregate portfolio from multiple potential trades, as well as to
determine credit charges, pricing, hedging and reserves from those
hypothetical trades. In certain instances, the CVA desk could potentially allow certain deals to be priced at a discount if they reduced the
counterparty risk from a portfolio perspective.
In some financial institutions, the CVA desk is structured as a
profit centre whose traders attempt to take active credit bets. For
most energy and commodity firms, however, the starting goal of the
CVA desk is likely to be the active management of credit exposures
with an emphasis on credit risk hedging and loss minimisation.
CONCLUSION
Counterparty and liquidity risk management in energy and
commodity portfolios is undergoing a revolution driven by efforts to
price and hedge those risks. CVA is gradually becoming an integral
part of the risk management process of energy and commodity
trading firms by helping to adjust valuations, and also in setting
credit and liquidity risk charges.
There are various methods to calculate CVA, from relatively
simple discounting of cashflows using credit risk-adjusted curves to
the more complex simulation-based potential exposures coupled
with default and recovery rates.
Valuation and risk measurement models and systems that fail to
incorporate counterparty and liquidity risk adjustments are ignoring
a material risk that could impact the accuracy of fair value and P&L
calculations, as well as the validity of risk metrics used throughout
the firm.
The implementation of CVA at the valuation and risk measurement level introduces other risks, such as potentially higher P&L
volatility and increased model risk arising from potential CVA estimation errors, but the benefits often outweigh the risks. Firms with
the ability to price and manage credit risk proactively will have a
competitive advantage over those that continue to manage those
risks in a passive and reactive fashion.

The Past, Present and Future of
China’s Futures Market: Trading
Volume Analysis
Wang Xueqin
Zhengzhou Commodity Exchange
This chapter will review the development of China’s futures market
since the early 1990s, with corresponding analysis of futures trading
volume. It will discuss the two phases of clean-up and rectification
necessitated by the development of China’s futures markets and the
establishment of its regulatory regime in the 1990s. In this context, it
analyses the trading volumes of China’s futures market between
2000 and 2011, particularly trading characteristics in 2011. This
analysis will help to explain why the trading volume of futures and
options rose worldwide but dropped in China during the same
period, as well as the reason why China’s futures market has latterly
been experiencing greater success. The last part of this chapter will
offer some predictions based on the huge potential for furthering the
futures market in China. These predictions include a trend towards
loosening product control, incorporating exchanges and the further
opening up of the futures market in China. Finally, this chapter will
conclude that a futures market with a stable trading volume will
conform to the principle of “making progress while ensuring
stability”. Such progress will be aided by research on the insurance
function of futures options, grasping the developing direction of
options early on and accelerating the innovation of futures products
and new futures business.

COMMODITY INVESTING AND TRADING
THE PAST
In 1990, with the approval of the State Council, the Zhengzhou Grain
Wholesale Market1 was founded as the first futures pilot programme
in China. Since then, China’s futures market has continued to
develop, moving from “chaos” to “governance” – including two
phases of clean-up and rectifications in the 1990s, as well as standardisation development in the 2000s. The futures market has grown
steadily in scale, with laws and regulations increasingly implemented, market functions well-performed and international
influence becoming even more significant. This has been especially
true since 2004, with more futures contracts being listed and traded,
forming an almost complete commodity futures market system
consisting of agricultural, metal, energy and chemical products.
The first 10 years (1990–2000)
In the 1990s, along with the establishment of a market-based
economic policy, China gradually opened its free commodity
market, resulting in frequent fluctuations in commodity prices. The
government began to develop a wholesale market of food, metals,
materials and other commodities, and futures trading of these products was gradually promoted. For a time, the commodity wholesale
markets and futures exchanges flourished everywhere in China.
From 1990 to 1993, the number of futures exchanges increased
rapidly, while futures contracts became multiply listed and the
markets were over-speculated. There were then more than 50 futures
exchanges in China, leading to vicious competition between the
exchanges. Disorderly market trading, market manipulation and
insider trading also occurred frequently during that time.2 Over a
thousand futures commission companies were founded, although
their operation and management verged on the chaotic. Customers
were often cheated and the interests of investors violated. The
brokerage services for overseas futures trading developed too fast to
be brought under regulation in a timely manner. The futures market
entered a stage of blind development.
The first phase of clean-up and rectification
On November 4, 1993, the State Council of the People’s Republic of
China issued the “Notice to Resolutely Stop the Blind Development
of the Futures Markets”, and started the first clean-up and rectifica410

tion in the futures market. The key measures adopted included
reducing the number of futures exchanges and futures products, as
well as suspending bulk trading for several commodities that were
closely related to the people’s livelihood but the price of which were
still subject to policy control – such as steel, sugar, coal, petroleum
and vegetable oil. On May 18, 1995, the Treasury bond futures
contract was also suspended. By the end of the first clean-up and
rectification, only 14 exchanges were approved to remain in business, while just 35 futures contracts were approved, divided into
formally listed contracts and trial-based contracts. Figure 16.1 shows
the number of listed futures and total futures trading notional
turnover by year.
Therefore, the main measures taken in the first clean-up and rectification were:
❏ reduce the amount of futures exchanges and futures contracts;
❏ suspend bulk trading for several commodities that were closely
related to the people’s livelihood and the prices and were still
subject to policy control, such as steel, sugar, coal, petroleum and
vegetable oil;
❏ suspend trading for Treasury futures on May 18, 1995;
❏ suspend approval for futures companies, review futures companies and implement a licence system;
❏ strictly control overseas futures trading;
❏ strictly control the participation of state-owned enterprises and
institutions, and financial institutions in futures trading; and
❏ establish a centralised and unified regulatory regime.
The second phase of clean-up and rectification
After the first phase of clean-up and rectification, there were still too
many futures exchanges and futures brokerage firms with problematic operations, and a few institutions and individuals were
manipulating the market to make exorbitant profits. There were
numerous incidences of illegal futures trading in overseas markets.
The supervisory administration had weak supervision powers and
retrograde supervisory methods.
In August 1998, the State Council issued the “Circular on Further
Rectification and Regulation of Futures Market”, in which the principles of continuing the pilot project, strengthening regulation,

for the second clean-up and rectification in China’s futures market.
The main measures included the further rectification, cancellation
and consolidation of futures exchanges. Three futures exchanges

were retained, in Shanghai (Shanghai Futures Exchange, SHFE),
Zhengzhou (Zhengzhou Commodity Exchange, ZCE) and Dalian
(Dalian Commodity Exchange, DCE), and the exchange management system was upgraded. In order to fully perform the functions
of price discovery and hedging for futures markets and further
contain excessive speculation, the listed futures contracts were
reduced from 35 to 12, with 23 futures contracts de-listed. The 12
commodities remaining were copper, aluminium, soybeans, wheat,
soybean meal, mung bean, natural rubber, plywood, long-shaped
rice, beer barley, red bean and peanuts.
The measures for the second phase also included the level of
minimum registered capital for futures brokerage firms being
increased to US$4.82 million. In 1998, after the increase of registered
capital, there were about 180 futures brokerage firms remaining in
normal operation. In addition, the China Securities Regulatory
Committee (CSRC) was created and “Interim Regulations on
Administration of Futures Trading” implemented.3
Determine the regulatory regime
After the clean-up and rectification, CSRC was appointed as the
centralised and unified regulatory commission for China’s futures
market, a regulatory change that created steady and wellfunctioning futures markets. In addition, China’s futures market
withstood the impact of the financial crisis of 2007–08; due to the
influence of the crisis, price volatility increased, especially in
commodity futures. The global financial crisis also impacted upon
the growth rate on China’s futures market. In 2009, this plunged to
20.72% from 87.24% in 2008, down 66.52%, showing that the
centralised and unified regulation had been successful and deserved
high credit, and also that it provides useful experience for the development and supervision of other commodity futures and financial
derivatives in China.
On November 24, 1998, the CSRC approved six modified contracts
for soybean, wheat, mung bean,4 copper, aluminium and natural
rubber, and on November 27, it approved modified contracts for
wheat and mung bean, to be re-listed and traded again. These
approvals marked a turning point in China’s futures markets in the
latter stages of its first decade. The second significant event was the
implementation of “Interim Regulations on Administration of

New futures contracts promoted
By the end of 2011, there were 31 futures contracts listed in four
futures exchanges in China, covering agricultural, industrial, energy
and financial products. Futures contracts for Treasury bonds, crude
oil, coking coal and even potato and egg were also being considered.

THE PAST, PRESENT AND FUTURE OF CHINA’S FUTURES MARKET: TRADING VOLUME ANALYSIS
In addition, steam coal futures contracts at the Zhengzhou
Commodity Exchange, coking coal and iron ore futures contracts at
the Dalian Commodity Exchange, crude oil futures contracts at the
Shanghai Futures Exchange and debt futures contracts at the China
Financial Futures Exchange were prepared and subject to regulatory
approval (see Table 16.2).
Futures companies gradually opened up
Chinese brokerage companies also became qualified for overseas
futures business. At the end of June 2001, the CSRC officially
published “Administrative Method for Overseas Futures Hedging
Business of State-owned Enterprises”, a list of state-owned enterprises that were allowed to participate in overseas futures hedging
business. By end-2005, 31 enterprises obtained the qualification of
overseas futures business.
Foreign capital participated shares into Chinese futures companies
By 2013, there were only three Sino–foreign joint venture futures
companies in China: Galaxy Futures, CITIC Newedge and JPMorgan
Futures. On December 2, 2005, ABN of Royal Bank of Scotland was
approved to set up the first joint venture futures company with
Galaxy Futures in China. The foreign party, ABN Financial Futures
Asia Co Ltd, held 40% of the shares, while on the Chinese side,
Galaxy Securities held the remaining 60% of shares. CITIC Newedge
was formerly known as CITIC Futures – in January 2007, overseas
strategic partner Newedge Group was launched, founded by Société
Générale and Banque de L’lndochine with a 50–50% ownership ratio.
The futures business of the group was carried out by Banque de
L’lndochine and the Pegasus Group. On September 26, 2007,
Guangzhou Zhongshan Futures was renamed as JPMorgan Futures,
with JPMorgan holding about 49% of shares indirectly.7
Chinese FCMs started to set up branches in Hong Kong
The China Securities Regulatory Commission approved six Chinese
future commission merchants (FCMs) to set up branches in Hong
Kong in March 2006, namely China International Futures, Yong’an
Futures, GF Futures, Nanhua Futures, Jinrui Futures and Green
Futures.

Financial futures successfully launched
China Financial Futures Exchange (CFFEX), approved by the State
Council and the CSRC, was set up by five shareholders: Shanghai
Futures Exchange, Zhengzhou Commodity Exchange, Dalian
Commodity Exchange, Shanghai Securities Exchange and Shenzhen
Securities Exchange, with each of the shareholders contributing
US$16.05 million. The CFFEX was founded on September 8, 2006, in
Shanghai. On April 16, 2010, CSI300 stock index futures started to be
listed and traded on CFFEX.
Trading volume of China’s futures market (2000–10)
Since the early 2000s, the trading volume of Chinese futures has
increased exponentially. The annual average growth rate of China’s
futures market between 2000 and 2010 was 43.16%.
In 2001, the trading volume of Chinese futures stood at 60.23

million contracts. The trading volume of global futures and options
was 4.4 billion contracts, and trading volume of global futures was
about 1.8 billion. The trading volume of global commodity futures
and options was about 400 million, and the volume of global
commodity futures was about 380 million contracts.
A decade later, the trading volume of Chinese futures had grown
to 1.52 billion lots and global futures was about 11.2 billion. The
growth in size of China’s markets as a percentage of the total global
market for all futures and for commodity futures is shown in Figure
16.5.
Global futures volumes in China’s futures markets increased from
3.34% in 2001 to 13.6% in 2010. For the first half of that period, the
market share of China was no more than 5%. Over the period 2001–
10, the ratio for futures and options increased from 1.37% to 6.82%,
illustrating the slower growth of options trading relative to futures
trading in China. During the 11th five-year plan, the market share of
China’s futures market to global futures and options market
increased exponentially.
For commodity futures, the ratio of China’s increased from 15.99%
of the global volume to 53.65% in 2010. When including options
volumes, China’s market increased from 14.61% to 50.95% of global
futures and options volume in 2010.
To summarise, between 2001 and 2010 the rapid increase in
trading volume made China’s futures market the largest commodity

market in the world. On the other hand, the average annual share of
the Chinese futures market share to global futures and options
remained low, reflecting that the trading volume of China’s futures
market in commodity options, stock futures and stock options are
not yet fully developed, with some products being totally absent
from China’s derivatives market. In 2010, China’s futures market
was one of the largest commodity futures market in the world,
accounting for a trading volume of 53.65% of the global commodity
futures market.
THE PRESENT
The micro characteristics of the market operation
The healthy development of the Chinese futures market has been
mainly based on the powerful spot market and an upward macroeconomic environment. China’s consumption volume of nearly all
the commodities underlying the futures contracts ranks among the
global top three consuming nations (see Table 16.4).
Open interest
As research shows,8 legal persons9 hold 40–60% of the 10 futures

coke, sugar, early long-grain non-glutinous rice and stock index
future are below 40%, which is relatively low.
Individuals are the main trading participants, usually more than
half of total trading volumes. The volume percentage12 of individuals for soybean No. 2 and rubber is over 80%; for gold, rebar,
LLDPE, coke, sugar, early long-grain non-glutinous rice, stock index,
zinc, PVC, strong gluten wheat, cotton and PTA is 50–80%; for
aluminium, lead, fuel oil, copper, soybean N0.1, soybean meal,
soybean oil, corn, palm oil, hard wheat and rapeseed oil is below
50%.
Price volatility between futures and spot
The assessment shows that the price volatility between futures and
spot is almost at the same level, except for the price of strong gluten
wheat, hard white wheat and early long-grain non-glutinous rice
contracts, whose volatilities are slightly higher than the actual price
volatility. Research data reveal that price correlation between futures
and spot on the majority of products in China’s futures markets are
stable and functional.

COMMODITY INVESTING AND TRADING
Declared hedging positions
Research shows that commercial enterprises mainly took short positions to hedge, based on the application for hedging quota, the use of
that hedging quota and the hedging of open interest. Based on the
actual situation in China, upstream enterprises often have a large
production capacity and therefore exhibit great enthusiasm for
futures market participation, while the downstream enterprises are
mainly small businesses, usually lacking hedging abilities and willingness. This results in a large amount of short hedging. In the
futures market, the manufacturers naturally hold short positions,
which creates a downward pressure on futures price. As the counterparty, speculators generally tend to hold long positions, hoping to
profit when the futures prices increase. Manufacturers pay a
premium to manage the risks coming from price fluctuations.
Price changes and price hit limits
Generally, the futures market prices ran smoothly in 2011, with the
hitting of the upper or lower price limits three times in a row
decreasing year-on-year.13 However, the futures prices of copper,
rubber, LLDPE, PVC, coke and palm oil experienced rather frequent
fluctuations, with each hitting the price limit more than 25 times.
LLDPE hit the price limit three times in a row on 16 occasions.
Short-term trading activity in the market
The short-term trading of futures was active, with intra-day trading
generally over 50% of total trading volume. In 2011, the three varieties that generated the largest proportion of day trading volume
were rubber, cotton and stock index futures. The intra-day trading
activity for these contracts accounted for over 80% of the total. The
three varieties with the lowest proportion of intra-day trading were
soybean No. 2, corn and hard wheat, all of which had an intra-day
trading proportion below 50%.
ANALYSIS OF TRADING CHARACTERISTICS IN 2011
The trading volume of futures and options rose worldwide but
dropped in China
Global futures and options market trading volume increased
Statistics show14 that the global futures trading volume increased by
7.4% from 12.049 billion transactions in 2010 to 12.945 billion transac422

tions in 2011, and that global options trading volume increased by
15.9% from 10.375 billion transactions in 2010 to 12.027 billion transactions in 2011. In 2011, the global futures and options trading
volume was 24.972 billion contracts, an increase of 11.4% from 22.425
billion transactions in 2010.
Futures trading volume in China decreased
According to the overall analysis from CFA data, in 2011 the trading
volume of the China’s commodity and financial futures was 1.054
billion transactions, a decrease of 32.72% from 1.567 billion transactions in 2010. China’s proportion of commodity and financial futures
trading volume in the world decreased from 6.82% in 2010 to 4.22%
in 2011. China’s commodity futures exchanges accounted for 53.65%
and 38.03% of the world’s futures trading volume for 2010 and 2011,
respectively.
It is worth noting that, despite an 11.36% growth in the global
futures and options markets trading volume in 2011, the global
commodity futures and options trading volume fell by 6%.
Agricultural commodity futures trading volume dropped by 26%
and non-precious metal futures fell by 33%. Although the national
futures trading volume declined by more than 30%, China’s financial
futures trading volume grew in 2011. CFFEX’s trading volume was
50.41 million transactions in 2011, an increase of nearly 10 % over
2010.
China’s commodity markets still world’s largest
In FIA’s “Annual Volume Survey”, ZCE ranked 11th in 2011 (12th
for 2010), SHFE ranked 14th in 2011 (11th for 2010) and DCE ranked
15th (13th for 2010). In 2011, the trading volume of ZCE decreased
only by 18%, while DCE’s decreased by 28% and SHFE by 50%.
Among the 32 countries for which FIA collected data, there are
commodity futures markets in 25 of those countries/regions. There
are 45 commodity derivatives exchanges, with total trading volume
reaching 2.64 billion transactions. Despite a decline of 34.01%
between 2010 and 2011, the trading volume of China’s commodity
futures in 2011 amounted to 1.003 billion contracts, accounting for
38.03% of the world volume and ranking first place globally. Figure
16.7 shows the proportion of total commodity future trading volume
by country.

Why the trading volume of futures and options rose worldwide
but dropped in China
The increase of the trading volume of futures and options globally
Below are some of the reasons behind the increase in trading
volumes.
❏ Most of global futures exchanges experienced an increasing
trading volume: among the 77 exchanges around the world, the
trading volume of 59 exchanges grew (accounting for 77%), 14
exchanges grew by 50% (accounting for 18%) and 11 exchanges
grew by 100% (accounting for 14%).

The decline in China’s futures trading volume
In 2011, although China’s futures market made significant achievement in improving the market structure, market function and futures
product innovation, the trading volume of the market suffered a
marked decline after five years’ rapid growth.16 There were three
reasons for this. First, the turmoil of the global economy, the structural transformation the domestic economy was facing and the
slowdown of the economic growth rate adversely impacted the
futures market. Second, factors such as the global loose-monetary
environment and the speculation of some commodities boosted the
price and volume of the futures market. Third, since the fourth
quarter of 2010 many measures have been taken to curb excessive
speculation, such as suspending the trading fee preferential system,
restricting the size of opening positions and raising the margin
requirement.
FUTURES COMPANIES AND TRADING VOLUMES
Futures companies
At the end of 2011, the margin held by the futures industry was
nearly US$25.59 billion. The various reserves that can be used to deal
with market risks was US$1.74 billion, out of which the risk reserve
of futures brokerage companies was US$304.98 million, the risk
reserve of future exchanges was US$1.09 billion and investor protection funds was US$345.10 million, which enhanced the industry’s
ability to control risk. However, compared to other financial
425
16 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:15 Page 426
COMMODITY INVESTING AND TRADING
institutions, futures brokerage companies’ overall strength was still
quite low. At end-2011, there were 161 futures brokerage companies
in China, and their total net capital was US$5.28 billion, only
US$32.10 million for each company on average. The net capital of the
top 10 futures brokerage companies only accounted for 28% of the
industry total, 32% for clients’ margin and 28% for fee income.
Futures brokerage companies’ income source was mainly brokerage
fee income and interest income from customers’ margin deposits. In
2011, the revenue of 161 futures brokerage companies was US$2.46
billion, out of which brokerage fees were US$1.60 billion and interest
income from customers’ margin was US$513.64 million. The annual
net profit was US$369.18 million, and some futures companies even
suffered a loss (data from CSRC).17
2012 trading volumes
In 2012, the total volume of futures market in China was 1.45 billion
contracts, with a notional value of approximately US$27.47 trillion,
increasing by 37.60% and 24.44% from 2011, respectively.
The trading volume of Shanghai Futures Exchange was 0.365
billion contracts, with a notional value of approximately US$7.12 trillion, increasing by 18.52% and 2.63% from 2011, respectively, and
with a market share of 25.19% and 26.06%, respectively.
The trading volume of Zhengzhou Commodity Exchange was
0.347 billion contracts, with a notional value of approximately
US$2.79 trillion, decreasing by 14.61% and 48.04% from 2011, respectively, and with a market share of 23.93% and 10.15%, respectively.
The trading volume of Dalian Commodity Exchange was 0.633
billion contracts, with a notional value of approximately US$5.35 trillion, increasing by 119.01% and 97.45% from 2011, respectively, and
with a market share of 43.64% and 19.47%, respectively.
The trading volume of China Financial Futures Exchange was 0.105
billion contracts, with a notional value of approximately US$12.17 trillion, increasing by 108.41% and 73.29% from 2011, respectively, and
with a market share of 7.24% and 44.32%, respectively.
THE FUTURE
The development of China’s futures market
The year 2012 witnessed the 22nd anniversary of the establishment
and development of China’s futures market. Since the early 1990s,
426
16 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:15 Page 427
THE PAST, PRESENT AND FUTURE OF CHINA’S FUTURES MARKET: TRADING VOLUME ANALYSIS
China’s futures market has grown to become one of largest
commodity futures exchanges in the world on the basis of trading
volume. In 2009, the total trading volume of China’s commodity
accounted for 43% of global volume, the biggest commodity futures
market globally.
There are three reasons for the prosperity of China’s futures
market. First, China’s futures market enjoys great support from
governmental policy. Since 1988, the establishment of a sound and
steady futures market has been included and referred to in the
government’s working report six times. Since 2004, requirements
have been raised in the No. 1 central document18 on the futures
market that futures derivatives for commodities should be transformed to a risk management instrument used by the real economy.
Second, the regulatory agency has strengthened the supervision of
the futures market to control risk. The regulatory agency always
gives top priority to strengthening the infrastructure of the futures
market. In addition, a good environment has been created for the
development of the futures market through continuously reinforcing
the basic regulations and institutions, steadily promoting new products, enhancing frontline supervision and strictly preventing market
risk.
Third, China’s futures market is generally managed well, not only
attracting a number of commercial enterprises to hedge, but also

increasing the integration of the futures market, cash market and
industrial entities. Also, the key reason is that the futures market
keeps up with China’s rapid economic development and soaring
commodity cash market.
Huge development space of China’s futures market
Although the trading volume of China’s futures market tops any
other, some development-restricting factors cannot be ignored. For
example, the futures market is faced with an environment of excessive regulatory restrictions, community monopoly,19 OTC disguised
futures,20 over-speculation and the problem of a lack of creativity in
development, competitiveness in exchange and low level of diversity
of futures varieties. While the domestic futures market is active, the
international pricing power is still out of China’s control.
Additionally, the monotonous operating system, improper regulatory system and single futures agent business21 have held back the
development of the futures market. It should be admitted that
China’s futures market has a long way to go. For instance, cash settlement of commodities has not been implemented and cross-product
arbitrage trading, transactions after closing (post-market session
trading), margin netting, SPAN, exchanges of futures for swaps and
options trading have not been instigated.
It is not yet possible to determine the steps necessary to achieve
these innovative projects or how long it will take and how difficult it
will be. To improve the international status of China’s financial
sector, a strong futures market is needed for support. To improve
China’s international competitiveness, the price discovery function
of futures markets should be given full play; to cope with the impact
from the international financial crisis, the hedging function of the
futures market should be further promoted; to improve the national
economy growth, service level of the futures markets should be
improved. Therefore, China enjoys a huge development opportunity
in the future.
Possible changes to China’s futures market
In spite of the high trading volume, the operating quality of China’s
futures market is not completely satisfactory. Since the financial
crisis of 2007–08, the global financial environment has changed
constantly, and the futures market has been confronted by great
428
16 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:15 Page 429
THE PAST, PRESENT AND FUTURE OF CHINA’S FUTURES MARKET: TRADING VOLUME ANALYSIS
uncertainty, offering both risks and opportunities. However, since
the early 1990s, China’s futures market has gone through stages of
blind development, rectification and regulatory change, and come to
a critical period of development, namely a development process
from quantitative change to qualitative change.
Undoubtedly, through this process some essential changes will
occur in China’s futures market. The first is that the futures market
will operate within the rule of the law, although there is still no
national futures law in China. Second, with the increasing number of
futures varieties, the coverage of futures products will be wider, and
futures markets should tightly track the actual underlying markets.
In addition, a speculative component will be more suitable for the
operation of the market. Third, there will be an increasing number of
innovations in the market-operating mechanism. The investor structure will be optimised and the proportion of institutional investors
will be raised. Fourth, with the improvement of international
competitiveness, the pricing power of the futures market will be
strengthened. Finally, new ways should be constantly opened up to
prevent market risks.
THREE MAJOR DEVELOPING TRENDS OF CHINA’S FUTURES
MARKET
The trend to loosen product-listing control
In order to curb the excessive amount of different types of futures
that were listed by the exchanges in the early days of the futures
market in the 1990s, an approval mechanism for the listed futures
varieties has been implemented. This prevents premature futures
varieties from listing, prevents the futures market from deviating
from the real economy, ensures the consistence of the futures and
cash market, controls market risk and standardises the market order.
However, under the approval mechanism, despite strong efforts for
promoting new products by the regulators and exchanges, a new
product often has a slow introduction process and may miss the best
time to market owing due to cumbersome procedures.22 This indicates that the inefficient administrative approval mechanism fails to
keep pace with the needs of the market and may hinder the pricing
function of the futures market. Thus, futures markets do not always
provide the risk management tools needed by all enterprises. In
addition, in the majority of futures exchanges around the world,
429
16 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:15 Page 430
COMMODITY INVESTING AND TRADING
nearly all varieties of agricultural futures have corresponding
futures options trading to allow flexible hedging of the agricultural
market risks. However, options trading has not appeared uniformly
in China’s futures markets, preventing domestic investors from
taking a more flexible approach to avoid market risks and also
restricting enterprises from participating in hedging. Therefore, in
the future, China’s futures market should relax product control and
gradually allow more listing of new products.
Corporatisation of the exchanges
China’s futures exchanges are structured uniquely, and their ownership is ambiguous and confusing, even to professionals in China.23
Although, in economic terms, according to the “Regulations on
Administration of Futures Trading”, 24 exchanges are seen as corporate legal persons or other economic organisations, in reality, in
terms of management, the institutional arrangements stipulated by
the “Futures Exchange Management Regulations”25 implies very
strong administrative factors. Therefore, the exchanges that act as
administrative organisations should be institutional legal persons.
On the other hand, organisationally, judging by the source of their
capital and their stated aims,26 exchanges that have features of social
community should be seen as social group legal persons (legal
persons are classified under several different categories in China).
Therefore, exchange systems should come under a special organisational model.27 In the author’s opinion, since the futures market is
market-oriented, complex and has high risk, it should be dynamically regulated for specialisation and legalisation, and even the
regulatory system itself should be market-oriented. The trend of the
corporatisation28 of exchanges around the world proves that corporatisation does not contradict the unified regulation of the futures
market by the government. Therefore, with the further opening-up
of China’s futures market as a part of its regulatory system,
exchanges should be equipped with a more advanced independent
market development force and much stronger competitiveness. As a
result, corporatised exchanges will become a development trend of
China’s futures market.
430
16 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:15 Page 431
THE PAST, PRESENT AND FUTURE OF CHINA’S FUTURES MARKET: TRADING VOLUME ANALYSIS
The further opening up of the futures market
Since 2008 (and especially since 2010), the internationalisation of the
China’s futures market has been a hot topic in the domestic futures
industry. A consensus has been reached, that it is the basic strategy of
China’s economic development to insist in opening up to allow
active participation in the international market. Since the futures
market directly serves the national economy, its internationalisation
is both an internal need for the development of China’s economy and
an irresistible development trend. There are two reasons to
explaining this. On one hand, our enterprises’ competing for the
pricing power of commodities requires the international futures
companies to provide intermediary services, and the prices of international commodities are based on the prices of international
commodity futures prices. Only by actively participating in the same
markets with the leading international futures companies and gradually expanding its influence, can China’s enterprises overcome the
difficulty of gaining pricing power. On the other hand, internationalisation can enhance the competitiveness of the futures companies. In
the process of internationalisation, in addition to domestic brokerage
business, futures companies can expand their businesses to foreign
business, as well as business that combines domestic and foreign
operations, which can improve operations and competitiveness. As
predicted, a series of opening-up measures, including product crosslisting, stock holding of foreign investors and international product
listings will become one of the main developing trends of China’s
futures market.
SUGGESTIONS
Stable trading allows for progress while ensuring stability
Influenced by factors such as state macro-control and complicated
market conditions, there has been a large fluctuation in the trading
volume of China’s futures market, especially in 2008. China’s futures
trading volume increased to 87.24% as a result of the international
financial crisis, before the rate decreased again by 20.72% in 2009. In
2010, it rocketed up again to 84.74%, but then sharply declined to
30.69% negative growth in 2011. On the contrary, since the early
2000s the proportion of US futures and options trading volume in the
world increased by more than 30%. Since the financial crisis, the
trading volume of the US market has gone up steadily. In 2011, its
431
16 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:15 Page 432
COMMODITY INVESTING AND TRADING
futures and options trading volume was 8.119 billion contracts,
14.01% more than the 7.121 billion contracts of 2012, occupying
32.51% of the total world shares, a small increase on the 31.94% of
2010. Thus, compared with the futures market of the US and other
developed countries, the stability of China’s futures trading volume
should further improve. Therefore, in a situation where futures
trading volume might decline, the relation between trading volume
and upgrading the quality of the markets should be handled
correctly and the scale of the futures market should be kept relatively
stable, both of which are not inconsistent with the principle of
“making progress while ensuring stability” of the Central Economic
Working Conference.29 That is to say, it would promote the transformation of China’s futures market from quantity expansion to quality
expansion.
The insurance function and development of options
International experience shows that, since the early 2000s, the global
options market has developed quickly. Statistics show that the
trading volume of options outpaced futures, apart from in 2010 and
2011. However, as the data of different classes of futures shows, the
trading volume of stock index option was several times that of stock
index futures, but commodity options trading volume was only onetenth of the futures volume.30

THE PAST, PRESENT AND FUTURE OF CHINA’S FUTURES MARKET: TRADING VOLUME ANALYSIS
As shown in Figure 16.9, in 2011 global energy options transactions accounted for 11% of its futures trading volume, global
agricultural options trading was 7.88% of the agricultural futures
and global non-precious metals and precious metals options trading
volume accounted for only 2.8% of the futures trading volume.
It can be seen that the original intention and purpose of listing
commodity options was mainly to serve as an insurance function for
futures and to enhance the quality of the futures market, not to
increase trading volume. For this reason, it is recommended that a
further study on the insurance function of options for futures and a
project on options training including simulated options trading is
needed.
CONCLUSIONS
For the optimal development of China’s futures market, the
following should be carried out:
further research and development of the crude oil futures;
rules of Treasury bond
433
16 Chapter CIT_Commodity Investing and Trading 26/09/2013 10:15 Page 434
COMMODITY INVESTING AND TRADING
overall operations, despite the growth rate having slowed. Under
these conditions, the development of the real economy needs a rapid
development of China’s futures market through greater specialisation, diversification and internationalisation. It offers the futures
markets a historic opportunity, but also some serious challenges.
China’s futures market needs not only a stable and functioning
market operation, but also much more innovation and opening up to
the world. This is the common aspiration for people in the industry
and is also the objective requirement for economic development in
China. The Chinese market has a great deal of room to develop, with
more new products to be listed, more market innovation and to be
more involved in the world’s derivatives business.
Finally, the question remains whether it is possible that these
markets will open to foreign traders. There is no schedule for foreign
investors to start trading in China’s commodity markets, but that time
is getting closer every day. Regulators are taking much more interest
in allowing foreign investors to trade in domestic markets, as
researched and provided by futures exchanges. Regulators are even
guiding exchanges to research some of the programmes aimed at
attracting foreign investors. In 2012, China’s regulators implemented
a series of measures to speed up the opening of the capital markets to
the outside world, including the qualified foreign institutional
investor (QFII) and renminbi qualified foreign institutional investor
(RQFII) systems. In 2012, 72 QFIIs were approved. At the time of
writing in 2013, a total of 213 qualified QFIIs had gained an approved
investment quota amounting to US$39.985 billion. At the same time,
in order to further expand opening to the capital market, in September
2012 the Shanghai and Shenzhen stock exchanges, as well as the China
financial futures exchange, held several QFII promotional activities in
the US, Canada, Europe, Middle East, Japan and South Korea to introduce foreign investors to China’s capital market. Furthermore, the
Shanghai futures exchange’s crude oil futures are expected to be introduced in 2013, with the aim of attracting more international investors
to participate in the financial and capital market in China.
1 Zhengzhou Grain Wholesale Market is the predecessor of Zhengzhou Commodity
Exchange. It is located on the south bank of the Yellow River, and is the first experimental
futures market in mainland China. Henan is a large agricultural province, whose output of
grain, cotton and oil rank among the top in China. It is an important base of quality agricultural products.

4 In the early 1990s, the Zhengzhou Commodity Exchange listed mung bean futures, the first
batch of domestic listed contracts. In 1998 and 1999, for two consecutive years it traded at a
peak of more than half of the national futures trading volume. In late 1999, after the margin
increased from 5% to 15–20%, the mung bean futures had no trades. In May 2009, after the
CSRC approved the “Request for Suspension of Mung Bean Futures Trading”, which was
delivered by ZCE in 2008, the mung bean contract was delisted.
5 On June 2, 1999, the State Council issued the “Interim Regulations on Administration of
Futures Trading”. After it was revised, the new “Regulations on Administration of Futures
Trading” took effect on April 15, 2007. The newest “Regulations on Administration of
Futures Trading” were approval by the State Council on September 12, 2012, taking effect on
December 1, 2012.

13 For example, if the accumulative price increase (decrease) based on settlement price in three
successive trade days (D1, D2, D3) of a futures contract reaches three times of the stipulated
increase (decrease) price limit in the contract, the exchange has the right to increase the
margin rate with the scale no more than three times of the trading margin standard in the
contract applicable at that time. Under circumstances of significant increased market risk
caused by the special situation of some futures contract, the exchange may take the
following measures according to the market risk of some futures contract, such as putting
limitations on margin movements, putting limitations on opening position and closing position, adjusting the trading margin standard of this futures contract and adjusting the range
of price limits of the contract.

18 “No. 1 central file” refers to the first document issued by the Central Committee of
Communist Party of China every year. It has become the proper noun for showing that
the Central Committee of Communist Party of China attaches great importance to rural
problems.
19 The monopoly behaviour of the futures industry in China is mainly reflected in the administrative monopoly, futures exchanges monopoly and futures brokerage industry
monopoly. For example, the regulatory department dominates the approval of varieties of
futures and products, listing locations as well as restricting every product to be listed on one
exchange without saying that listed procedures are cumbersome. In addition, in relation to
a futures company, an exchange has a much stronger voice and negotiation ability, etc.
20 In China, outside of futures exchanges, there are more than 200 electronic commodity
trading markets that trade almost the same contracts and use trading mechanisms and rules
similar to futures exchanges. This is called “disguised futures” or ‘quasi futures”. The
markets lack strict regulation and market rules, and their operation and implementation are
in chaos. To some extent, they inhibit the healthy development of China’s futures markets.
21 Since the early days, risk events have occurred with futures companies misappropriating
customer funds and allowing customers to carry out overdraft trading. However, futures
brokers firms are not allowed to trade their own accounts and can only trade for customer
accounts, promulgated and provisioned by the regulations on futures trading of September
1999. The main business of futures companies in China is to trade on behalf of their
customers, so the firm’s income mainly comes from commission.
22 The listing mechanism for new futures contracts in China adopts a non-market-approval
system. In order to list a new variety of futures contract, it must first undergo a repeated
research and review process by the futures exchange and then report to the CSRC accordingly. After examination and verification, CSRC then submits a report to the State Council,
which needs to consult the relevant state ministries and commissions, related industry
administration departments and even relevant provinces and cities. After getting all feedback, the State Council might make written instructions. A new variety of futures contract
will finally be launched.
23 China’s three commodity futures exchanges are institutional units implementing enterprise
management, while China Financial Futures Exchange is a corporate system, an enterprise
is a legal person. In fact, they are all to different extents the subsidiary of the regulatory
department.
24 Article 7: non-profit futures exchanges shall carry out self-regulation according to their
constitutions, and assume the civil liabilities with all their properties. A futures exchange
bears civil liabilities to the extent of all of its property. The persons in charge of futures
exchanges shall be appointed and dismissed by the futures supervision and administration
authority of the State Council. Article 18: The revenues obtained by a futures exchange shall
be managed and used in accordance with the relevant state regulations and may not be
distributed to members or diverted for other uses.
25 A futures exchange shall establish a board of directors. The chairman and the vice-chairman
shall be nominated by the CSRC and elected by the board.
26 Article 4: Registered capital of the membership futures exchange is divided into equal
shares, which is subscribed to by its members.
27 This is not only difficult to explain to most Westerners, but also to some Chinese.
28 The meaning is similar to “demutualisation” – ie, the move from a member-owned organisation to a publicly listed organisation.
