问一道题:NO.PZ2019103001000005

问题如下:

Daasvand asks Perreaux to analyze immunization approaches to liability-based mandates for a meeting with Villash Foundation. Villash Foundation is a tax-exempt client. Prior to the meeting, Perreaux identifies what she considers to be two key features of a cash flow–matching approach.

Feature 1:It requires no yield curve assumptions.

Feature 2:Cash flows come from coupons and liquidating bond portfolio positions.

Is Perreaux correct with respect to key features of cash flow matching?

选项:

A.

Yes.

B.

No, only Feature 1 is correct.

C.

No, only Feature 2 is correct

解释:

B is correct.

Cash flow matching has no yield curve or interest rate assumptions. With this immunization approach, cash flows come from coupon and principal repayments that are expected to match and offset liability cash flows. Because bond cash inflows are scheduled to coincide with liability cash payouts, there is no need for reinvestment of cash flows. Thus, cash flow matching is not affected by interest rate movements. Cash flows coming from coupons and liquidating bond portfolio positions is a key feature of a duration-matching approach.

Feature 2:Cash flows come from coupons and liquidating bond portfolio positions.


请问Feature不是cash flow matching特性吗?

嗨,爱思考的PZer你好:


Feature 2:Cash flows come from coupons and liquidating bond portfolio positions.


不是的,这里的关键在Liquidating bond portfolio positions,Liquidating就是卖出债券头寸变现。

只有在Duration-matching时,我们是需要提前卖出债券来偿还负债现金流的。

而对于Cash flow matching,我们是让Coupon现金流和债券本金现金流发生的时间,恰好就是负债到期的时间,所以我们不需要提前卖出债券(不需要Liquidating),债券自然到期的现金流就能偿还负债。
