Suppose that you buy, and after one year sell, a German bond. When you buy the bond the dollar euro exchange rate is 1 dollar = 1 euro. You pay 50 euros for the bond. You receive no coupon and when you sell the bond, you sell it for 60 euros. When you sell it, a euro is worth 0.80 dollars. What is your gain or loss in dollars? What is the rate of return on your investment?
