在国际贸易中货款结算期比较长,汇率经常发生波动,致使以外币结算货款的进出口企业面临汇率变动风险,特别是当企业与国外进口商签订销售合同,约定于数月后销售商品,并以外币结算货款时,就会遇到结算期汇率波动所引起的销售收入不确定给企业带来的经营风险。为了回避风险,企业往往通过在期汇市场上卖出与现货市场销售商品金额相等、交割期相同的期汇交易来锁定销售收入。从而 In international trade, the payment period is relatively long and the exchange rate fluctuates frequently. As a result, the import and export enterprises that settle the payment in foreign currencies are exposed to the risk of exchange rate changes. This is especially the case when enterprises sign sales contracts with foreign importers and agree to sell the goods in a few months. In foreign currency settlement of payment, you will encounter the settlement period exchange rate fluctuations caused by sales revenue uncertainty to the business risks. In order to avoid the risk, the enterprise often locks the sales income by selling the same amount of commodities in the futures market to sell goods in the spot market with the same delivery time. thereby
