NO.PZ2019010402000061

问题如下:

Suppose one year ago we entered a €200,000,000 three-year receive-fixed Libor-based interest rate swap with semi-annual resets (30/360 day count). The fixed rate in the swap contract entered one year ago was 4.5%. The value for the party receiving the fixed rate is:

选项:

A.- €648,079.61 B.

€648,079.61

C.

- €548,068.57

解释:

B is correct

本题考察的是利率互换求value。

先求出在t=1时刻的互换的固定利率:

i=1nPVi(1)=0.985222+0.966184+0.943396+0.917431=3.812233\sum_{i=1}^nPV_i\left(1\right)=0.985222+0.966184+0.943396+0.917431=3.812233

fixed swap rate = (1- 0.917431) / 3.812233=2.1659%

annulized: 2.1659% * 360/180 = 4.3318%

然后计算value,对于fixed receiver:

V= (0.045 - 0.0433) ×(180/360)×3.812233×200,000,000 = €648,079.61

用了下面的思路:

fixed leg: 4.5%*0.5 *3.812233+1*0.917431

另一边:1


两者相减,然后再乘以np。


请问下这个思路是只适用于float leg+ fix leg 是吗。

嗨,从没放弃的小努力你好:


用折现后的“收-支”来求t时间点的估值,是可以用于各种衍生品估值的。

我们现实和考试中最常见的利率互换是固定换浮动,原版书中也只讲了fixed-for-floating interest rate swap这一种互换的估值。

----------------------------------------------
虽然现在很辛苦,但努力过的感觉真的很好,加油!

目前题目答案中是先求fixed leg年化swap rate,然后剩余的利差折现到当前时间点,作为收益。 看老师回复折现后的“收-支”来求t时间点的估值,是可以用于各种衍生品估值的。不知道是不是用于本题所给出的信息量啊。如果适用的话,我之前做的思路做不出来,不知道问题出在哪里: fixed leg: 4.5%*0.5 *3.812233+1*0.917431 另一边:1 两者相减,然后再乘以np

嗨,爱思考的PZer你好:


因为我们假设30/360 day count,而且直接使用的折现因子,会有一定误差。

考试临近,同学会解题思路,自己手动可以算出答案即可,不需要纠结答案完全对的上,考场上选一个最接近答案的即可,本题AC都是负的,我们算出来是正的,且与答案B接近,很容易做出选择~

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