Assume that an importer in the United States in March of a year needs to pay DM 500,000 in three months. The current spot exchange rate is DM 1 = US $0.5000. To avoid the risk that the mark will appreciate in three months, it decided to buy four Deutchmark futures contracts expiring in June, trading at 1 Deutchmark = $0.5100. In June, the Deutchmark did indeed appreciate, with the spot rate of 1 Deutchmark = $0.6000 and the corresponding price of the Deutchmark futures contract rising to 1 Deutchmark = $0.6100. If you don't take the commission into account. Deposit n and interest, try to calculate the importer's net profit and loss.
