SPreAD TrADINg IN CUrreNCY FUTUreS
|
||||
Thus, the equal dollar value spread would consist of 1.6 BP contracts per euro contract, or 8 BP to
|
||||
5 euro.
|
||||
equity fluctuations in an equal-dollar-value intercurrency spread position will mirror the price
|
||||
ratio (or exchange rate) between currencies. It should be emphasized that price ratios (as opposed to
|
||||
price spreads) are the only meaningful means of representing intercurrency spreads. For example, if
|
||||
the BP = $1.50 and SF = $1.00, an increase of $0.50 in both the currencies will leave the price spread
|
||||
between the BP and SF unchanged, even though it would drastically alter the relative values of the two
|
||||
currencies: a decline of the BP vis-à-vis the SF from 1.5 SF to 1.33 SF.
|
||||
■ Intracurrency Spreads
|
||||
An intracurrency spread—the price difference between two futures contracts for the same currency—
|
||||
directly reflects the implied forward interest rate differential between dollar-denominated accounts
|
||||
and accounts denominated in the given currency. For example, the June/December euro spread
|
||||
indicates the expected relationship between six-month eurodollar and euro rates in June.
|
||||
1
|
||||
T o demonstrate the connection between intracurrency spreads and interest rate differentials, we
|
||||
compare the alternatives of investing in dollar-denominated versus euro-denominated accounts:
|
||||
S = spot exchange rate ($/euro)
|
||||
F = current forward exchange rate for date at end of investment period ($/euro)
|
||||
r
|
||||
1 = simple rate of return on dollar-denominated account for investment period (nonannualized)
|
||||
r2 = simple rate of return on euro-denominated account for investment period (nonannualized)
|
||||
alternative a:
|
||||
Invest in Dollar-Denominated account
|
||||
alternative B:
|
||||
Invest in euro-Denominated account
|
||||
1. Invest $1 in dollar-denominated account. 1. Convert $1 to euro at spot.
|
||||
2. Funds at end of period = $1 (1 + r1) exchange rate is S, which yields 1/S euro. (By definition, if S equals dollars
|
||||
per euro, 1/S = euro per dollar.)
|
||||
2. Invest 1/S euro in euro-denominated account at r
|
||||
2.
|
||||
3. Lock in forward exchange rate by selling the anticipated euro proceeds
|
||||
at end of investment period at current forward rate F.2
|
||||
4. Funds at end of period = 1/S (1 + r2) euro.
|
||||
5. Converted to dollars at rate F, funds at end of period = $F/S (1 + r2)
|
||||
(since F = dollars per euro).
|
||||
1 The eurocurrency rates are interest rates on time deposits for funds outside the country of issue and hence free
|
||||
of government controls. For example, interest rates on dollar-denominated deposits in London are eurodollar
|
||||
rates, while rates on sterling-denominated deposits in Frankfurt are eurosterling rates. The quoted eurocurrency
|
||||
rates represent the rates on transactions between major international banks.
|
||||
2 A short forward position can be established in one of two ways: (1) selling futures that are available for forward
|
||||
dates at three-month intervals; and (2) initiating a long spot/short forward position in the foreign exchange (FX)
|
||||
swap market and simultaneously selling spot.
