Answer:
In Japan, 90-day securities have a 4% annualized return and 180-day securities have a 5% annualized return. In the United States, 90-day securities have a 4% annualized return and 180-day securities have an annualized return of 4.5%. All securities are of equal risk, and Japanese securities are denominated in terms of the Japanese yen. Assuming that interest rate parity holds in all markets -then the yen-dollar spot exchange rate equals the yen-dollar exchange rate in the 90-day forward market (Option A).
Explanation:
Based on the fact that, both in Japan and USA, 90-day securities have a 4% annualized return, the yen-dollar spot exchange rate equals the yen-dollar exchange rate in the 90-day forward market.
