‘Arbitrage’ Types



Pure Arbitrage: No risk nothing and earn
more than the riskless rate
Near Arbitrage: Assets are identical or
almost, but there is no guarantee of profit
Speculative Arbitrage:

Investors take advantage of what they see as
mispriced and similar (though not identical) assets

Triangular Arbitrage

Convert money through three currencies
$ → £→ € → $

Arbitrage opportunity if the ending dollar value
does not equal the beginning dollar value.
$ ≠ $
£
€
6 (of 24)
Triangular Arbitrage: Example
Case 1


$1 → £0.52 → €1.33 → $1.10 GAIN $0.10
$1 ≠ $1.10
£0.52
€1.33

Triangular Arbitrage: Example
Case 2 (using different FX rates)



$1 → £0.49 → €1.20 → $0.90 LOSS ($0.10) ▪
If you get a loss of ($0.10), just go the opposite
direction beginning with $0.90 and you will gain
$0.10. ▪
$1.00 ≠ $0.90
£0.49
€1.20

Is there an arbitrage opportunity?


$ → € → C$ → $ ▪
$ → € : $1.00 x 0.6898 = €0.6898
€ → C$: €0.6898 x 1.7491 = C$1.2065
C$ → $: C$1.2065 x 0.9422 = $1.1368
Arbitrage Profit of $0.1368


$1.00 x 0.6898 x 1.7491 x 0.9422 = $1.1368 ▪

Notation

FN(j/k)

number of j needed to buy 1 k in N months
Difference from Spot Rate Notations



‘F’ not ‘S’
N because you always need to specify the time of
a forward rate
NOTE: S(j/k) = F0(j/k)

Premium versus Discount

Premium: A currency is trading at a premium
when (in American terms) the forward rate is
increasing.


Market Expectation: The currency will appreciate
and the US dollar will depreciate.
Discount: A currency is trading at a discount

decreasing.

Market Expectation: The currency will depreciate
and US dollar will appreciate.

Psychology–The ‘Black Box’
Forward Rates are only market expectations
(unless you lock them in with a contract).
All prices, rates, etc. are based on the current
‘information set’.
New information (‘News’)

Speculation versus Hedging



Speculation: Taking a position that increases
the risk of your portfolio.
Hedging: Taking a position that decreases
the risk of your portfolio.
In practice, the distinction can be blurred.

Forward Premium/Discount


Premium or discount (f) as an annualized
percentage change from the spot rate.
Notation



fN,j is the forward premium at N of currency j in
American terms.
fN,$ is the forward premium at N of US dollars in
European terms.
Essentially, this gives you, in percentage
terms, how much the forward rate is expected
to moves from the spot annually.
