问题如下:
Consider a zero-coupon bond with a face value of USD 100 and a maturity of ten years. What is the DV01 and the effective duration when the ten-year rate is 4% with semi-annual compounding? (Consider one-basis-point changes and measure rates as decimals when calculating duration.)
解释:
The value of the bond is
When the ten-year rate increases to 4.01%, the value decreases by 0.065944 to 67.231190. When the ten-year rate decreases to 3.99%, the value increases by 0.066012 to 67.363145. The DV01 can be estimated as the average of 0.065944 and 0.066012, or 0.065978. The effective duration is
题目问:一个零息债券的面值是100USD,期限是10年,当利率是4%,半年付息一次时,DV01和effective duration是多少?
债券的价格V0=100/(1+4%/2)^(10*2)=67.297133
当利率上升1bp到4.01%时,债券价格V+=100/(1+4.01%/2)^(10*2)=67.23119
价格下降0.065944
当利率下降1bp到3.99%时,债券价格V-=100/(1+3.99%/2)^(10*2)=67.36314
价格上升0.066012
DV01=(0.065944 + 0.066012)= 0.065978
effective duration=0.065978/(67.297133×0.0001)=9.804
烦请写下计算步骤先谢谢。另外,零息债券久期不是到期日吗?根据57页另一个求DV01的公式不是同样可以求吗?当然两个结果绝对不相同。请问错误在哪里呢?
