Multinational Financial Management: Interest Rate Parity
The general relationship between spot and forward exchange rates is specified by a concept called interest rate parity. It specifies that investors should expect to earn -Select-a highera lowerthe sameItem 1 return in all countries after adjusting for risk. The relationship is expressed in the following equation:
Both the forward and spot rates are expressed in terms of the amount of home currency received per unit of foreign currency. Your overall return will be higher than the investment's stated return if the currency in which your investment is denominated -Select-decreasesappreciatesItem 2 relative to your home currency. On the other hand, your overall return will be lower if the foreign currency you receive-Select-decreasesappreciatesItem 3 in value. If this relationship doesn't hold, currency traders will buy and sell currencies engaging in -Select-cannibalizationarbitrageflotationconversionItem 4 until the relationship does hold.
Quantitative Problem: Assume that interest rate parity holds. In the spot market 1 Japanese yen = $0.006, while in the 180-day forward market 1 Japanese yen = $0.0067. 180-day risk-free securities yield 1.55% in Japan. What is the yield on 180-day risk-free securities in the United States? Round your answer to 2 decimal places. Do not round intermediate calculations.

Explanation / Answer
According to the interest rate parity,
forward rate($/yen)(180 days)
= spot exchange rate* {((1+(R$*180/360))/(1+(RYen*180/360))}($/yen)
= 0.006* {((1+(R$*180/360))/(1+(0.0155*180/360))}($/yen) ...(RYen=1.55%,R$=?)
= 0.0067
=> ((1+(R$*180/360))/(1+(0.0155*180/360))=0.0067/0.006
=> (1+0.50*R$)/(1+0.0155*0.50)=0.0067/0.006
=> (1+0.50*R$)/(1.00775)=0.0067/0.006
=> 1+0.50*R$=(0.0067/0.006)*1.00775
=> R$=2*((0.0067/0.006)*1.00775-1) = 0.2506=25.06%
