题目详情

By how much will the price of a ten year zero coupon bond change if the yield

increases by ten basis points?

解析

久期近似:

ΔBBDΔy.\frac{\Delta B}{B}\approx -D\,\Delta y.

零息债久期等于到期:D10D\approx 1010bp=0.00110\text{bp}=0.001,故

ΔBB10×0.001=1%.\boxed{\frac{\Delta B}{B}\approx -10\times 0.001=-1\%}.
