NO.PZ201512020800000101

问题如下：

1. Based upon Exhibit 1, the forward premium (discount) for a 360-day INR/GBP forward contract is closest to:

选项：

A.

–1.546.

B.

1.546

C.

1.576

解释：

C is correct.

The equation to calculate the forward premium (discount) is:

$F_{f/d}-S_{fld}=S_{f/d}(\frac{\lbrack{\displaystyle\frac{Actual}{360}}\rbrack}{1+i_d\lbrack{\displaystyle\frac{Actual}{360}}\rbrack})(i_f-i_d)$

$S_{f/d}$ is the spot rate with GBP the base currency or d, and INR the foreign currency or $< e m > f < / e m > . S_{f / d}$ per Exhibit 1 is 79.5093, i f is equal to 7.52% and i d is equal to 5.43%.

With GBP as the base currency (i.e. the “domestic” currency) in the INR/GBP quote, substituting in the relevant base currency values from Exhibit 1 yields the following:

$F_{f/d}-S_{f/d}=79.5093(\frac{\lbrack{\displaystyle\frac{360}{360}}\rbrack}{1+0.0543\lbrack{\displaystyle\frac{360}{360}}\rbrack})(0.0752-0.0543)$

$F_{f/d}-S_{f/d}=79.5093(\frac1{1.0543})(0.0752-0.0543)$

$F_{f/d}-S_{f/d}=1.576$

考点：利率平价公式的计算.

解析： Covered IRP:

$F_{f/d}-S_{fld}=S_{f/d}(\frac{\lbrack{\displaystyle\frac{Actual}{360}}\rbrack}{1+i_d\lbrack{\displaystyle\frac{Actual}{360}}\rbrack})(i_f-i_d)$

其中，GBP代表的是本币，而INR代表的是外币，于是直接代入数字到上述公式中可得：

$F_{f/d}-S_{f/d}=79.5093(\frac{\lbrack{\displaystyle\frac{360}{360}}\rbrack}{1+0.0543\lbrack{\displaystyle\frac{360}{360}}\rbrack})(0.0752-0.0543)$

$F_{f/d}-S_{f/d}=79.5093(\frac1{1.0543})(0.0752-0.0543)$

$F_{f/d}-S_{f/d}=1.576$

这个答案的公式怎么看不懂，和课件的不一样啊，下图左边是课件，右边是答案。按照课件算出来的结果和答案算出来的不一样

嗨，爱思考的PZer你好：

Hello，亲爱的同学~

这两个公式，是不一样的哦。

就是有计算差异的。

一个是精确公式，一个是近似公式。

近似公式很方便理解：F 和S的升贴水，等于利差。

也就是说，在利差上赚的钱，要在升贴水中亏出去，最终不赚不亏，这才是均衡。

我们考试的时候，是选择题，这两个公式都可以用，选一个最接近的答案就可以。

----------------------------------------------
努力的时光都是限量版，加油！
