The annualized US risk-free rate is 8% and the Germany risk-free rate is 5%. Assume that any period rates less than a year can be interpolated (i.e. if you invested for 6 months then you would receive 4% in the US). The spot quote is €0.80/$ while the 3-month forward quote is €0.7994/$. You can borrow either $1,000,000 or €800,000. According to IRP, is the forward quote correct? If not, what should it be?
If the forward quote is not correct, lay out the steps to implement an arbitrage.
Spot Rate 1 $ = Euro 0.80
3 months fair forward rate = 0.80(1+0.05*3/12)/(1+0.08*3/12)
= 0.80*1.0125/1.02
= Euro 0.7941/$
According to Interest Rate parity, Fair rate is Euro 0.7941/$
Hence, the forward quote is not correct
It should be Euro 0.7941/$
Borrow Euro 800,000
Convert into Dollar and get 800,000/0.80 = $1,000,000
Invest for 3 months and get 1,000,000(1+0.08*3/12)
= $1,020,000
Convert into Euro and get 1,020,000*0.7994 = Euro 815,388
Repay Loan 800,000*(1+0.05*3/12) = 810,000
Arbitrage Profit = Euro 5,388
