Lecture X
Definition of derivatives (simple but consistent with regulation)
A derivative is a transaction that is designed to create price exposure,
and thereby transfer risk, by having its value determined – or derived –
from the value of an underlying commodity, security, index, rate or event.
Unlike stocks, bonds and bank loans, derivatives generally do not involve
the transfer of a title or principal, and thus can be thought of as creating
pure price exposure, by linking their value to a notional amount or
principal of the underlying item.
Types derivatives products include
- Forward
- Futures
- Options (American, European, barrier, path dependent)
- Swaps (FX, interest rate, CCS, swaptions)
- Hybrid securities (security with derivative attached, a.k.a. structured note)

Lecture X
Definition of a forward contract as a simple example
The simplest and perhaps oldest form of a derivative is the forward
contract. It is the obligation to buy or borrow (sell or lend) a specified
quantity of a specified item at a specified price or rate at a specified time
in the future. A forward contract on foreign currency might involve party A
buying forward at t1 (and party B selling) US$1,000,000 for Euros at
$1.3405 on t91.
A forward rate agreement on interest rates might involve party A
contracting on t1 to borrow (party B lending) $1,000,000 for three months
(91 days) at a 2.85% annual rate beginning t91.
What does this achieve economically? Buying forward creates a long position in the
underlying item (e.g. foreign currency). If the future market price (exchange rate) in the
spot market appreciates in value, then the long position will gain in value much like that
from owning the item outright. This creation of price exposure then facilitate hedging
and speculation.

- History Evidence of derivatives trading as early as 1750 B.C. in Mesopotamia
Holland in 1595 – creation of Amsterdam laws to facilitate transfer of title
Chicago Board of Trade, 1848 – trading in central market with standardized contracts
End of Bretton Woods monetary system – foreign exchange futures – 1971- lead to
the creation of financial futures on foreign exchange rates in 1972 on CME and
NYMEX
Black-Scholes-Merton Options Pricing Formula – 1973 – boosted the trading of
options
CBOT Futures on Treasury securities in 1977
(Eurodollar interest rates at CME in 1981)
IBM- World Bank cross currency swap in August 1981
Kansas City Board of Trade – stock index futures in 1982 (CME’s S&P was two
months later
By end of 2006, the notional amount of derivatives outstanding reached $486 trillion,
and the annual trading volume of exchange traded futures and options reached
$1,808 trillion.

- Usefulness Price discovery
- Everyone can use price to inform their decisions about consumption and investment.
Bond traders can look at corn, copper and oil prices to form inflation views, and various IR
futures allow the creation of a yield curve. Thus an externality of information.
Risk shifting
-Hedging – defined as reducing existing exposure to a risk
-- Efficiency gain arising from shifting risk from one party to another that is better willing
or able to bear it.
-- Keep in mind that both sides of transactions might be hedging – does just shift to risk
loving counterparty. In this case the risk is not only shifted but eliminated.
-Speculation – defined as increasing existing exposure to a risk
-- Speculators are thought to add economic value by helping to complete markets in
which there is an imbalance between short- and long hedgers.
-Unbundle and repackage risks
-- e.g. the risk on a foreign currency bond can be decomposed into FX, IR and credit risk
that are all priced and hedged separately – and the market value of the risk on the bond
can be priced and hedged through options trading.
Cost of capital
- improve upon inefficiencies or imperfections in financial markets
- e.g. borrow at variable rate where credit premium is lower and then swap into fixed
interest rate and end up with lower fixed rate borrowing cost than available by issuing
fixed rate debt.
Lecture X
- Public Interest Concerns This issue is addressed briefly here – will be address fully in Seminar II
Misuse
Outflank prudential regulation (regulatory arbitrage)
Avoid taxation (tax arbitrage)
Distort financial statement (creative accounting)
Abuse
Fraud
Manipulation
Systemic risk
Excess risk taking – greater amount of risk taking for given amount of capital, the
danger of which is the externality of risk taking.
Non-transparency – no one knows how much open interest exists or who holds it

Lecture X
- Why derivatives? Comparison to banking, securities, and insurance
Banking
No principal – but FX swap is like a $ bank loan that is collateralized 100% with
local currency. Malaysian government had to account for this in capital controls in
1997. Pre-paid forwards used by Enron and Chase to create credit through
derivatives desks.
Securities
No principal – but can generate the same total returns as equity or bond, e.g. the
use of stock index futures to create portable alpha investment strategy
Insurance
Options, like insurance, are priced as risk premium. But options are usually not
capped, and insurance is based on damages from pre-existing risk exposure.

- Use of derivatives and derivatives markets Price discovery
This is often overlooked as a key economic function of derivatives
markets.
Not overlooked by US law. Primary motive for regulating the markets is
to protect the price integrity of the markets. It is in order to help ensure
the accuracy and efficiency of these prices that law stricted prohibited
fraud and manipulation.
Registration helps to prevent fraud by keeping criminals out of the
markets. Registration requirements include background checks,
competency test (equivalent of Series 7) and for financial firms it includes
adequate capital and business model.
Reporting helps detect and deter manipulation. Reporting requirements
include large trader reporting data.
Prior to being amended by the Commodity Futures Modernization Act of 2000, the
Commodity Exchanges Act read as follows.
“‘Futures’ are affected with a national public interest. Such futures transactions are carried
on in large volume by the public generally and by persons engaged in the business of buying
and selling commodities and the products and byproducts thereof in interstate commerce.
The prices involved in such transactions are generally quoted and disseminated throughout
the United States and foreign countries as a basis for determining the prices to the producer
and consumer of commodities and the products and by-products thereof and to facilitate the
movements thereof in interstate commerce. Such transactions are utilized by shippers,
dealers, millers, and others engaged in handling commodities … The transactions and
prices of commodities on such boards of trade are susceptible to excessive speculation and
can be manipulated, controlled, cornered or squeezed, to the detriment of the producer or
the consumer and the persons handling commodities and products and byproducts thereof in
interstate commerce, rendering regulation imperative for the protection of such commerce
and the national public interest therein.” (Section 3 entitled “The Necessity of Regulation”)
Incidentally, the new section of the Act is entitled “Protection of the Public Interest” and reads
more briefly and less literarily to convey a similar economic message.
The transactions subject to the Act are … are affected with a national pubic interest by
providing a means for managing and assuming price risks, discovering prices, or
disseminating pricing information through trading in liquid, fair and financially secure trading
facilities.
- Use of derivatives and derivatives markets Risk shifting
1. Hedging: reducing existing risks
2. Unbundling risks: decomposing risks associated with an investment.
 Derivatives allow different risks to be traded and priced separately so that
investors need not hold all the risks associated with an investment in order to
have the risks and returns of the other risks. For example, an investors may
want the credit risk and interest rate risk of an emerging market bond but not
the exchange rate risk and can eliminate it by hedging.
3. Similarly, derivatives can be combined with traditional capital instruments in
order to tailor a security to the preferences of investors or to tailor the nature of
the liabilities of a security issuer to their ability to hold to risk. For example,
Chilean corporations borrow abroad through dollar loans or notes where they
can get long term debts. and then swap back into the peso to avoid exchange
rate risk.
4. Derivatives can be used to improve upon the inefficiencies in capital markets.
For example, borrows pay lower credit spreads on variable rate debt and can
then swap into fixed rate obligations less expensively than borrowing at fixed
rates.

- Abuse of Derivatives 1. Fraud – costs everyone in the market by undermining confidence,
and costs most everyone as greater expenses are incurred to avoid
or detect it. There are many types of fraud: front-running, wash
trades, sharp trading practices.
2. Manipulation
1) Protecting the integrity of market prices.
In Section 3 of the Act entitled, “Necessity for Regulation,” it stated that
futures are "affected with a national public interest." "The prices in such
transactions are generally quoted and disseminated throughout the United
States... for determining the prices to producer and consumer of
commodities and the products and by-products thereof and to facilitate the
movements thereof in interstate commerce."
In short, these prices are important because they are used not only by
those directly involved in the market but also by producers and consumers
throughout the economy. Fraud and manipulation are therefore a matter of
pubic interest – not just a problem for those who are defrauded or suffer the
losing end of the manipulation – because they threaten the integrity of the
markets i.e. of the price discovery process.
2) Providing a safe and sound market for risk management.
Derivatives markets provide economically useful tools for hedging and risk
management. The extent of their use depends on their affordability, and
leverage contributes to their affordability. Leverage also encourages
speculation and greater risk taking. Capital and collateral (called margin
for exchange traded derivatives and securities) requirements are the
pillars of financial market safety and soundness. They function by
providing a buffer against losses and a disincentive for excessive risk
taking. Like securities markets and the banking sector, a well regulated
derivatives market should have capital and collateral requirements that
are commensurate with the level of exposure to market risk and credit
losses. While this will increase the cost, i.e. lower the affordability of
OTC derivatives, the market should benefit overall from the improved
investor confidence in the marketplace.
3) Small distortions in market prices can have a large impact on the economy.
Keep in mind that manipulation does not have to be grand in the old fashion way, but
can consist of small changes in prices. If prices of winter wheat are off only 3 cents a
bushel, and U.S. farmers produce and sell at home and for export 1,612 million bushels,
then it will be a $48.36 million cut in income for the farmers on the winter wheat crop
alone. That same 3 cents applied to the 9.5 billion bushels of corn would affect income
by $285 million – almost six times the impact. That small price change would equal 1%
of the nation’s net farm income for all crops. Similarly, consider a manipulation of 3
basis points (0.03%) on Treasury securities. If that has to be paid by the government on
all outstanding Treasury securities held by the public, then it would cost the Treasury
and hence U.S. taxpayers about $1 billion annually.
The ability of the government to detect and deter fraud and manipulation is dependent
on the reporting requirements of market participants. Market prices, trading volume,
open interest and larger trader positions are the minimum information needed to
maintain adequate market surveillance. This is the standard for exchange traded
derivatives and is similar for the stock and government bond market.
Information-based manipulation:
This involves insider trading or making false reports on the market. An example of the former is
the manner in which Enron executives made early moves to cash out their employee stock
options and sell their security holdings. An example of the latter is illustrated by the way
Wall Street firms associated with Enron made “buy” recommendations to their customers
and the wider market while enhancing their firms’ profits from holding Enron securities,
underwriting and other business relationships.
Action-based manipulation:
This involves the deliberate taking of some actions that changes the actual or perceived value
of a commodity or asset. For example, managers of a firm short the firm’s stock and then
announce the loss of an important contract or the closing of factories. After they profitably
cover their short positions by buying at lower prices, they negotiate new contracts or
reopen the factories. Note that these two examples show that action based manipulation
can be combined with insider trading. Similarly, but without insider information, investors
may take a position on the stock and then pursue legislation or regulatory changes that
might be passed to change the value of the assets.
Trade-based manipulation:
This is the classic case of either unexpectedly amassing a large position in
the market, or more likely using one market to capture the gains from creating
a price distortion in another interrelated market. How does this work? In the
latter case, a manipulator acquires a large long position in the derivatives
market in crude oil by entering forward or swap contracts for future delivery or
future payments based on the future price of oil. If the derivatives positions
were transacted through the OTC market, then neither the government nor
any other market competitor would be able to observe the total position of the
manipulator. Then the manipulator goes into the spot or cash market for
crude oil and amasses a large enough inventory of oil (and also contracts to
sell it to buyers who will not resell it) in order to push up the present oil price.
This raises the value of the long derivatives positions so that they can be
offset or unwound profitably. Then if the manipulator can sell off the amassed
inventory without incurring substantial losses, the manipulation will be
successful. Keep in mind that the manipulator does not have to buy all the oil
in the world, but merely that portion that is to be delivered in the market that is
linked to the derivatives contracts. (See the oil price manipulation case
below.)
EXAMPLES:
The CFTC charged two futures traders with manipulating the futures and
options market for U.S Treasury bonds in October of 1992. The two
sold 13,000 bond futures contracts (roughly $13 billion in notional
value) and bought 31,000 put options (roughly $31 billion in notional
value). The traders were arrested on the trading floor, expelled from
the Chicago Board of Trade, fined $2.25 million by the CFTC and
faced criminal charges.
In June of 1993, the CFTC charged that the financial firm Fenchurch used
exchange traded derivatives called futures in conjunction with a large
share of the cash market to manipulate the interest rate on special
collateral repurchase agreements on 10-year U.S Treasury notes and
profit by forcing short position holders to deliver a more expensive
Treasury security to fulfill the futures contract. Towards the expiration
date of the futures contract, Fenchurch held a long futures position of
12,700 contracts (approximately $12.7 billion in notional value) or 76%
of the open interest in the market. The repo rate on the 10-year note
fell below 0%, i.e. reached negative
EXAMPLES:
Tosco won a settlement claiming that Arcadia Petroleum (a British subsidiary of the Japanese firm Mitsui)
engineered an elaborate scheme to manipulate oil prices in September of 2001 through the use of OTC
derivatives and a large cash market position to corner the market in Brent crude oil. (Brent is a blend of
crude oils pumped out of the North Sea and shipped from a terminal at Sheffield Island off Scotland). As a
result, the price of Brent Crude soared between August 21st and September 5th and pushed its price to a
premium over West Texas Intermediate crude oil (WTI). WTI, which is a higher quality oil, is normally
priced about $1 above Brent, but during this period Brent sold for more than $3 above WTI. This artificial
price hike occurred at a time of widespread strikes and social protest in Europe.
Dated Brent, which acts as a price marker for many international grades, is physical crude traded on an
informal market, rather than a regulated futures exchange. This lack of regulation poses problems for oil
producers and consumers seeking a fair price, said Robert Mabro, director of the Oxford Institute for
Energy Studies and a leading Brent expert.
"There are regular squeezes in the Brent market," Mabro said. "In the trading community, people are fed up.
This general view that you can do whatever you like in an informal market is okay, as long as you regulate
the market a bit. But if it's a free-for-all, you're back to the cowboy age."
A typical Brent squeeze involves a company quietly building a strong position in short-term swaps called
contracts for difference, or CFD's, for a differential not reflected in current prices. The company then buys
enough cargoes in the dated Brent market to drive the physical crude price higher, which boosts the CFD
differential, Mabro said.
The company may lose money on the physical side, but it's more than compensated from profits on its
offsetting paper position in the short-term swaps market, Mabro said.
"The whole trick is to collect more money in CFDs than you lose on the physical squeeze," Mabro said.
"People seem to do it in turn. It depends on who's smart enough to move in a way that nobody notices
until it happens."

Main Policy Implications
Questions:
1. Volatility: does the presence of derivatives markets add to existing market
volatility (especially in exchange rate)
2. Does the use of derivatives to exchange rate risk result in capital outflows
that negate the benefits of capital inflows?
3. Do derivatives markets weaken the ability of a central bank to manage
exchange rate policy by giving potential attackers greater leverage?
Other policy issues:
1. How does it affect monetary policy intervention in context of interest rate
derivatives
2. Can derivatives be used effectively by Treasuries or development
agencies to hedge government revenues linked to commodity price
fluctuations

- Conceptual Overview –
Economic Rationale for Regulation:
Regulation arises from market imperfections such as externality, incompleteness,
destructive competition, natural monopoly and MAC events that invoke national
security.
Each feature in the following regulatory framework is linked to some market
imperfection that creates need to improve upon what would be a competitive
market outcome.
-Registration Requirements Registration requirements: how and why this is important, including anti-fraud and
stability issues.
FIGHTING FRAUD
Economic incentives include those for committing fraud. Financial markets cannot do an
adequate job of policing themselves from fraud. Efforts to do so would suffer from lack of
authority, free-rider problems, possible protectionist motives and the usual problems of
injustice associated with militias, posses, mobs and armed gangs. So the task is best
assigned to legitimate public authority.
Registration is key step in fighting fraud by requiring key personnel with fiduciary and
investment management responsibilities to submit to
i) background checks to see whether their criminal past, such as convictions for fraud, would
disqualify them from certain responsibilities
ii) competency exams, e.g. series 7, for responsible individuals to prove they are know what
they are doing – right or wrong
iii) adequate capitalization
iv) good business plan
SURVEILLANCE
Provides supervisory authorities with a census of who is involved in market activities.
Can be combined with record keeping requirements to oblige participants to maintain audit
trail.
-Reporting Requirements Reporting requirements: how and why this is important, including anti-fraud,
detect and deter manipulation, transparency, and market surveillance.
Markets function most efficiently when all participants are fully informed, yet economic
incentives encourage firms to hoard information. Disclosure or reporting requirements are
needed to discourage information, and do so in a timely and consistent manner, so that
participants can adequately analysis of information. For example, the 1933 and 1934
securities acts in the US focused on establishing reporting requirements to improve market
transparency. Another US example is the 1936 Commodity Exchange Act.
Also, there is another externality to the information content in prices or the price discovery
process. The externality arises from the use of the information by people who are not
directly involved as market participants. Bond traders look to commodity futures prices in
order to form views on inflation and in turn prices in the fixed income market. Ag producers
in remote or distant areas are affected by prices determined in Chicago, New York or
London. If those prices are distorted, then all the other make erroneous decisions based on
the false prices. Thus there is a public interest in protecting the integrity of market prices.
Yet another externality is the nature of information as a public good. Because I am informed
by some information it is not prevent you from being informed. If we are all equally informed
then eliminates the benefit for one or few have exclusive access to information. This takes
away the benefit to the few but it makes the market more efficient.
-Reporting Requirements Everyone says they are for transparency, but there is no agreement on what it is or how to
get there. Here are some specifics.
1. Financial institutions, including dealers, brokers, exchanges and electronic trading
facilities, must report details of their derivatives trading activities to supervisory authorities.
The authorities will in turn provide aggregated information to the broader public. The
proprietary details will be for the eyes of the authority to detect vulnerabilities as they emerge
and pricing pressures. (Like exchanges reporting market prices, trading volume and open
interest, this will facilitate the production of pricing and other key market information for all
participants and the public). This is not necessarily costly – merely CC-ing the authorities on
the confirm documents will inform them.
2. Large trader reporting requirements – informs surveillance authority of large positions in
the market in order to help detect and deter market manipulation.
3. Quarterly and annual reporting of the financial condition of key financial institutions such
as dealers, brokers, exchanges and clearing houses, will help detect the build-up of
vulnerabilities in the financial system.
- Capital Requirements Capital requirements: how this can be applied to derivatives, with comparison on balance
sheet items.
There is an externality from risk taking. Some who are not involved in the investment
decision and will not benefit from the returns, will be negatively impacted if the investment
fails. Consider the employees of firms in developing countries whose securities prices are
clobbered by recent contagion from subprime market disruptions. Their losses are not costs
to subprime market participants and thus are externalities to those market participants.
It is not immediately feasible to reunite the social and price costs of the market disruption.
However what is feasible is to constrain or govern the risk taking of firms and individuals so
that their risk taking is in governed by the proportion of capital they put at risk. Capital
requirements set the minimum standard for putting capital at risk in order to pursue higher
risk and returns.
Otherwise there is a serious moral hazard as limited liability business organization gives
firms a free put with a zero strike price. Otherwise there will be fallout from the economic
impact of larger and reckless failed investment strategies. The capital requirement is not just
a solvency condition but a governor or constraint – though a prohibition – on the investment
decisions of key financial institutions.
- Collateral Requirements Collateral requirements: comparison of exchange-traded to OTC derivatives markets,
including
Like capital requirements, collateral requirements are aimed at governing risk taking so as to
reduce potential externalities.
Collateral is especially important to derivatives markets because there is great leverage and
collateral has the effect of governing the extent of (or the degree of) the leverage.
Collateral also helps manage counterparty credit risk that builds up in the process of active
OTC derivatives trading.
- Orderly Market Rules Orderly Market Rules. Some examples are:
• Position limits
• Price limits
• Designated market makers with requirements to maintain bid/ask quotes
• Standards for contract design (there are many dimensions to this issue) such as economic
usefulness, avoidance of manipulation or excess volatility,
• Minimum tick size or bid/ask
• Prohibition against certain misconduct such as front-running, wash trading and the like
• Suitability or ‘know thy customer’ requirements
- Clearing Issues Clearing procedures: multilateral clearing house (central counterparty) compared to bilateral netting and
clearing.
Clearing House
• Multilateral
• Offers AAA counterparty risk – deep capitalization provides protection
• Collateral is paid up front
• Daily, and if needed interday, market to market with margin adjustments reduces
credit risk
• Offers complete legal netting through novation
• Providing trading efficiency through lower back office costs
• Concentrates credit risk in a single financial institutions and thus warrants close
attention
Bilateral OTC clearing
• Post trading activity - confirmation, clear and settle - is done principal to principal
• No collateral requirement, and industry practice is uneven and often below par. Refco
advertised lowest margins in the market.
• Typical arrangement: i) counterparties allowed to trade under a threshold before
posting collateral; ii) a variety of assets are allowed to be posted as collateral (some not
necessarily liquid); iii) if counterparty gets into trouble then they are ‘super-margined’
and must post additional collateral (thus acts as crisis accelerator).
• Disperses risk to some degree, although concentration in few derivatives dealers
reduces the benefit of dispersion.
