Problem:
Assume that locational arbitrage ensures that spot exchange rates are properly aligned. Also assume that you believe in purchasing power parity. The spot rate of the British pound is $1.80. The spot rate of the Swiss franc is .3 pounds. You expect that the one-year inflation rate is 7 percent in the U.K., 5 percent in Switzerland, and 1 percent in the U.S. The one-year interest rate is 6% in the U.K., 2% in Switzerland, and 4% in the U.S. What is your expected spot rate of the Swiss franc in one year with respect to the U.S.dollar?
