为什么是C

NO.PZ2020033001000031

问题如下:

Alextrasza Bank entered the one-year correlation swap contract as a fixed correlation receiver. The nominal principal of the contract is 100 million. If the two assets of the target three assets have a daily correlation of 0.5, 0.5, 0.3. How much will Alextrasza Bank receive at maturity if the fixed correlation rate is 0.2?

选项:

A.

$43,000,000.

B.

$23,000,000.

C.

-$23,000,000.

D.

-$43,000,000.

解释:

C is correct.

考点:平均相关性计算

解析: 计算公式如下ρrealized =2/(32 -3)*(0.5+0.5+0.3)=0.43

$100,000,000*(0.2-0.43)=-$23,000,000

这道题中,是receiver(就是seller)

当相关系数上升时,payer有gain。

同理在相关系数下降时,payer损失,然后seller就有收益。

为什么这里是C

同学你好!


这道题先根据题目条件算 realized correlation

银行是 Receiver,所以 payoff = Fixed ρ - Realized ρ
