4. Assume that interest rate parity exists. One year ago, the spot rate of the euro was $1.40 whereas the spot rate of the Japanese yen was $0.01. At that time, the one-year interest rate of the euro and Japanese yen was 3%, compared to 7% for the one-year U.S. interest rate. One year ago, you used the one-year forward rate to derive a forecast of the future spot rate of the euro and the yen one year ahead. Today, the spot rate of the euro is $1.39, and the spot rate of the yen is $0.009. Which currency did you forecast more accurately?
