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:

怎么判断此题是连续复利?

嗨,努力学习的PZer你好:


这里需要结合外汇市场的常识来判断。欧元币值是大于美元的, USD/EUR exchange rate is 1.25,意思是1EUR = 1.25USD。

所以YYY是USD(美元是quote currency),而XXX是EUR(欧元是base currency)。建议考试之前可以多看看主流货币的汇率对比,一般来说是英镑>欧元>美元>日元。


按照利率平价理论,高利率的国家的远期汇率倾向于贬值(贴水),题目给出的是欧元利率更高,所以欧元的F应该是比S小的。所以是0.04-0.07.

嗨,从没放弃的小努力你好:


参考基础班讲义P237-238:

连续复利或者离散复利都可以,不会影响你选出正确选项的。

虽然现在很辛苦,但努力过的感觉真的很好,加油!

此题中Current USD/EUR exchange rate is 1.25,表示xxx/yyy,那usd应该为基础货币,应该是e的(0.07-0.04)次方?
