Suppose that the current exchange rate is SF1.25/$ and three month forward exchange rate is SF1.30/$. The three-month interest rate is 4 percent per annum in United States and 8 percent per annum in Switzerland. Assume that you can borrow up to $1,000,000 or SF 1,250,000.

b) If your answer to part a is no, how would you realize a certain profit via a covered interest arbitrage? Also determine the size of the arbitrage profit.
