解析:根据题目的信息,我们可以看到美元的利率低于人民币的利率,同时美元对人民币的远期合约中的价格表明美元未来会贬值,因此投资者可以通过投资人民币赚取利润。用这种方式来判断的话,可以免去计算的步骤。
下面也通过定量的方式来演示计算。

要想获取套利,需要在今天:
(1) 以2.8%的利率借入1USD,用于购买CNY, 按照即期汇率来计算,可以购买6.9013CNY。
(2) 6.9013CNY存入银行可以获得4.3% 的利息,同时签订远期合约,远期合约规模是6.9013*1.043=7.1980,锁定远期汇率0.1532USD/CNY.
一年之后,
(1) CNY投资一年之后的价值为6.9013*1.043=7.1980CNY,用这7.1980CNY可以以forward price 0.1532购买USD:7.1980*0.1532=1.1027USD
(2) 偿还美元的借款本金和利息 1 USD * 1.028=1.028 USD, 那么最终可以获得1.1027-1.028=0.0747 USD 盈利。
S0*(1+2.8%)/(1+4.3%)=0.142817
