没太明白为什么要在二叉树里面的利率上再加一个OAS

问题如下:

Based on Exhibits 1 and 2, the effective duration for the AI bond is closest to:

选项:

A.

1.98.

B.

2.15.

C.

2.73.

解释:

B is correct.

The AI bond’s value if interest rates shift down by 30 bps (PV–) is 100.78. The AI bond’s value if interest rates shift up by 30 bps (PV+) is 99.487.

Effective duration=[(PV-)-(PV+)]/[2× (ΔCurve) × (PV0)]= (100.780 - 99.487)/ (2 × 0.003 × 100.200)=2.15

老师上课说过,OAS是剔除了权利影响的spread,分子的现金流已经包含了权利影响了。那为什么还可以在二叉树的利率上直接加OAS,但是现金流又还是按照初始的coupon rate来计算呢?

嗨,爱思考的PZer你好:


OAS衡量的是信用风险,也就是embedded option bond剔除权利影响后,完全因为信用因素导致的spread。

正是因为分子含权,所以分母无需含权,所以采用OAS。
