问题如下:

You are examining the exchange rate between the U.S. dollar and the Euro and have the following information:

Current USD/EUR exchange rate is 1.25.

Current USD-denominated 1-year risk-free interest rate is 4% per year.

Current EUR-denominated 1-year risk-free interest rate is 7% per year.

According to the interest rate parity theorem, what is the 1-year forward USD/EUR exchange rate?

选项:

A.

0.78

B.

0.82

C.

1.21

D.

1.29

解释:

The forward rate, Ft, is given by the interest rate parity equation:

where S0 is the spot exchange rate, r is the domestic (USD) risk-free rate, and rf is the foreign (EUR) risk-free rate, t is the time to delivery.

Substituting the values in the equation:

老师您好,从看视频到做题,除了可以自行判别的 ‘usd/cny’,‘cnyusd’ 这种类型的汇率写法(不论哪个在前都可以知道1美元对应更多人民币),其余的汇率写法xxxyyy或xxx/yyy 是否都是可以认作xxx作为base, yyy作为quote?所以xxx对应国家的interest rate作为分母,yyy对应国家的interest rate作为分子?还是说有别的理解方式呢?感觉比学之前更混乱了:(

对的。

同学你好,考试一般给的都是xxx/yyy这种哈,意味着n个x能换1个y,你就把斜杠后面(分母)位置看成是一个苹果就好了。

至于xxxyyy这种没有斜杠的写法变换成有斜杠的写法就是yyy/xxx,顺序刚好倒过来。

所以在xxxyyy里面,xxx作为base,yyy作为quote 然后变换成xxx/yyy后,xxx作为quote,yyy作为base?
