Suppose 1 U.S. dollar equals 1.60 Canadian dollars in the spot market. 6-month Canadian securities have an annualized return of 6\% (and thus a 6-month periodic return of 3\%). 6-month U.S. securities have an annualized return of 6.5% and a periodic return of 3.25%. If interest rate parity holds, what is the U.S. dollar-Canadian dollar exchange rate in the 180-day forward market? a. 1 U.S. dollar =1.6039 Canadian dollars b. 1 U.S. dollar =0.6265 Canadian dollars c. 1 U.S. dollar =0.6235 Canadian dollars d. 1 U.S. dollar =1.5961 Canadian dollars e. 1 U.S. dollar =1.0000 Canadian dollars
