风险敞口的计算

* 问题详情,请 查看题干

NO.PZ202304070100009101

问题如下:

The fair value of bond B2 is closest to:

选项:

A.

€1,069.34.

B.

€1,111.51.

C.

€1,153.68.

解释:

Correct Answer: A

The following table shows that the CVA for the bond is €42.17, the sum of the present values of expected loss. The steps taken to complete the table are as follows.


Value of the bond if the bond were default free would be:

€60 × DF1 + €60 × DF2 + €60 × DF3 +€1,060 × DF4 = €1,111.51.

Fair value of the bond considering CVA = €1,111.51 – €42.17 = €1,069.34

老师,您好!


解析中已经算出了没有违约的情况下,债券的价格就是1111.51。那么在计算CVA的过程中,每年的风险敞口是怎么得来的呢?风险敞口应该就是未来现金流折现到假设的违约发生时的价值,不可能超过VND(1111.51)才对啊。麻烦老师补充一下,谢谢!

嗨,从没放弃的小努力你好:


不对,每一年的Exposure包括两部分:当年的Coupon,和以后现金流的折现值。可以参考一下这道题https://class.pzacademy.com/qa/25990,exposure有些也是比VND大的。
