1. Short half-year GBP 50,000 in the futures market, close the position while receiving the payment from the British company, and increase the amount of GBP against the US dollar, so there is a risk that the cash exchange of the British company at the time of payment is not completely synchronized with the price difference of USD 2 and the price difference of half-year foreign exchange, and there may be a small profit and loss.

2. Short-sell 50,000 pounds in the futures market for half a year, and deposit it in the British bank after receiving the payment from the British enterprise. At the same time, 50,000 pounds was hedged against the US dollar to preserve the exchange rate, but the half-year value of 50,000 pounds has been converted into interest on the British pound.
