The old lady was absolutely afraid of the economic situation, she wanted to make sure that her money would be safe, so, she went to speak with a broker. The broker expressed understanding and explained the following: We will invest part of your money in futures contracts for Euros, it is an absolutely safe instrument where you pick the settlement price and you know how much you will get for the Euro and you do not lose a penny. You have to post margin but do not worry, you can always walk out of the contract if you want. Now, we can also enter into a Foreign Exchange swap, where the constant stream of cash you will receive over the years will keep your money safe. Furthermore, we can calculate the value of the swap in such a way that you always receive more than you pay. The old lady looked at the broker, did not say a word, and went away muttering curses against the ignorance of some brokers. Was she right?
