C is correct.考点Mark –to-Market Value 解析BBQ公司进入了一份时长6个月的外汇合约。它担心卖出GBP贬值，所以该合约是卖GBP买US即在合约到期时公司要以1.5512USGBP的价格卖出GBP。现在过去三个月，那么截止当前，该合约还剩3个月到期。由于3个月后公司需要进入一份与期初头寸相反的对冲合约来结束期初的合约，所以那时BBQ应该买入GBP，卖出US买入GBP就需要以做市商的卖价（ask）买入。所以我们求得未来3个月 USGBP的市场报价。即1.5505 +0.00061=1.55111。由于买价是1.55111，卖价是1.5512。所以3,600,000 GBP的本金在合约到期时的利润就是（1.5512-1.55111）×3,600,000 = 324US但是这个数值是到期时合约的价值,我们对其往前折现3个月才能求得合约在当前的价值。本题中的标价货币是US所以折现时候需要使用US3个月利率水平。即US3241+0.0045(90/360)=US323.64\frac{UStext{ 324}}{1+0.0045{(90/360)}}=UStext{ }323.641+0.0045(90/360)US324=US323.64 衍生品的思路解发可以再写一下吗？用衍生品的方法算出来的不一样… 算着算着就混乱了
