Barton Wilson, a junior analyst, is a new hire at a money center bank. He has been assigned to help Juanita Chevas, CFA, in the currency trading department. Together, Wilson and Chevas are working on the development of new trading software designed to detect profitable opportunities in the foreign exchange market. Obviously, they are interested in risk-free arbitrage opportunities. However, they have also been instructed to investigate the possibility of longer-term currency exposures that are not necessarily risk-free. To test the logic of their new software, Wilson gathers the following market data: • Spot JPY/USD exchange rate = 120. • Spot EUR/USD exchange rate = 0.7224. • U.S. risk-free interest rate = 7%. • Eurozone risk-free rate = 9.08%. • Japanese risk-free rate = 3.88%. • Yield curves in all three currencies are flat. In addition to in-house currency transactions, the new software program is also intended to provide insight into currency exposure and hedging needs for the bank's major customers. These customers typically include large multinational firms. Essentially, the bank wants to provide consulting services to its clients concerning which currency exposures offer the greatest possibility of appreciation. In this process, the bank will rely on deviations from international parity conditions as an indicator of long-term currency movements. Wilson obtains the following data from the econometrics department: • JPY/USD spot rate one year ago =116. • EUR/USD spot rate one year ago = 0.7200. • Anticipated and historical U.S. annual inflation = 3%. • Anticipated and historical Japanese annual inflation = 0%. • Anticipated and historical Eurozone annual inflation = 5%. One of the bank's major customers has significant portions of its business in Japan, and the Eurozone and has long exposure to both currencies. The customer has traditionally hedged all currency risk. However, the customer's new risk manager has decided to leave some currency exposure unhedged in an attempt to profit from long-term currency exposure. Wilson wants to approximate the forward discount/premium for the JPY against the USD 12 months from now. According to the approximate version of interest rate parity, the JPY would most likely trade at a:
Answer options
A: 3.12% forward premium against the USD. Correct answer
B: 3.12% forward discount against the USD.
C: 1.7% forward discount against the USD.
Correct Answer:
A. 3.12% forward premium against the USD.
Explanation

According to interest rate parity (IRP), the currency with the lower nominal interest rate must trade at a forward premium relative to the currency with the higher nominal interest rate to prevent arbitrage opportunities. The approximate relationship for the forward premium or discount is given by the interest rate differential between the two currencies: $F - S \approx S \times (r{\text{price}} - r{\text{base}})$. Here, the Japanese yen (JPY) risk-free interest rate is 3.88%, while the U.S. dollar (USD) risk-free interest rate is 7.00%. Because Japan's interest rate is 3.12% lower than the U.S. interest rate (3.88% - 7.00% = -3.12%), the JPY must trade at an approximate 3.12% forward premium against the USD.

Why Incorrect

B. A forward discount would apply if the JPY interest rate were higher than the USD interest rate, which is not the case here.
C. 1.7% is incorrect as it does not reflect the exact 3.12% differential between the U.S. (7.00%) and Japanese (3.88%) risk-free rates.
