1.Suppose the spot exchange rate between the US dollar and Canadian dollar is US$0.75/C$. The Canadian dollar and US dollar risk-free rates are 2.5% and 1.5% per annum, respectively, compounded annually. The price of a two-year European call option with an exercise price of US$0.76/C$ is US$0.03. What is the price of the option in US dollars if it is a put?
2.Suppose that the US dollar interest rate is 2% per annum and Canadian dollar interest rate is 3% per annum for all maturities, annually compounded. The current exchange rate is US$0.75/ C$. Under the terms of a swap agreement, a bank receives 4% per annum in Canadian dollars and pays 5% per annum in US dollars.
