Suppose that the spot rate for British pounds is $1.76. The USA
risk-free rate is 1.1% and the UK risk-free rate is 2.2%; both are
compounded annually. One-year forward contracts are currently
quoted at a rate of $1.75.
6.3 Identify a strategy with which a trader can earn a profit at
no risk by engaging in a forward contract, regardless of her view
of the pound’s likely movements. Assume the trader’s domestic
currency is US dollars.
6.3.1 Describe carefully the transactions the trader would make.

6.3.2 Calculate the rate of return that would be earned from
this transaction. [2]
6.4 Suppose the trader simply shorted the forward contract. It
is now one month later. Assume interest rates are the same, but the
spot rate is now $1.72. What is the gain or loss to the
counterparty on the trader?
