Currency Option Pricing with Binomial Model On January 11, the spot exchange rate for the U.S. dollar is $0.70 per Canadian dollar. In one years

Currency Option Pricing with Binomial Model

On January 11, the spot exchange rate for the U.S. dollar is $0.70 per Canadian dollar. In one years time, the Canadian dollar is expected to appreciate by 20 percent or depreciate by 15 percent. We have a European put option on U.S. dollars expiring in one year, with an exercise price of 1.39 CND$/US$, that is currently selling for a price of $2.93. Each put option gives the holder the right to sell 10,000 U.S. dollars. The current one-year Canadian Treasury Bill rate is 2 percent, while the one-year U.S. Treasury Bill rate is 3 percent, both compounded annually. Treat the Canadian dollar as the domestic currency.

What is the estimated value of this put option by using the binomial model? (5 marks)

b. Calculate the estimated value of this put option for U.S. T-Bill rates of 0%, 1%, 2%, 4%, 5%, and 6%. Plot these values in a graph (by hand or using Excel), with put option values on the y-axis and U.S. T-bill rates on the x-axis. What can we conclude about the relationship between foreign interest rates and foreign currency put option values? (2.5 marks)

c. Calculate the estimated value of this put option for Canadian T-Bill rates of 0%, 1%, 2%, 4%, 5%, and 6%. Plot these values in a graph (by hand or using Excel), with put option values on the y-axis and Canadian T-bill rates on the x-axis. What can we conclude about the relationship between domestic interest rates and foreign currency put option values? (2.5 marks)
