Assume the following information:

Quoted Price

Spot rate of Canadian dollar $.80

60day forward rate of Canadian dollar $.79

Annual Canadian interest rate 4%

Annual U.S. interest rate 2.5%

Given this information, what would be the yield (percentage return) to a U.S. investor who used covered interest arbitrage? (Assume the investor invests $1,000,000.) What market forces would occur to eliminate any further possibilities of covered interest arbitrage?
