A one-year forward transaction on the US dollar is an agreement in which we agree today to exchange $1 for F pounds one year from now. F denotes the forward quote.

Suppose that you see a forward quote of F = 0.8. Does there exist an option-based arbitrage strategy? If you answer no, explain why and if you answer yes construct this strategy and prove there is arbitrage.

Suppose that one-year pound interest rate is 5% and the current exchange rate is USD/GBP=0.7. What is the US dollar interest rate?
