See the following analysis:
If you expect $6,543,800,000+to arrive within one month to pay $80,000,000. You can sell $6,543,800+at the exchange rate of 1 USD for RMB in 8 yuan. The contract expires in one month. If the exchange rate becomes 8.3, you will lose 3 million. But the $6.5438+million you received can be exchanged for 83 million. It happens to be 80 million. Similarly, if the maturity exchange rate is 7.8, your maturity income is 2 million, but the 6.5438+million you received can only be exchanged for 78 million. Also hedge 80 million.
Of course, the above analysis is a state of principle. In practice, foreign exchange futures need to pay some handling fees. But very low. Don't think about how much it costs to sell 10 million dollars. In fact, the margin of futures is only110, which means that you only need to pay 10 million dollars to sell10 million dollars. The final liquidation is limited to actual fluctuations, and your deposit will not be lost.
