根据题目已知条件:
SF term structure is :
R(90 day)=5.2% R(180-day)=5.4% R(270-day)=5.55% R(360-day)=5.7%
求出
B90=1/{1+0.052(90/360)}=0.9872 以此类推 B180=0.9737 B270=0.90 B360=0.9461
0.8 $/SF
根据公式
1.25=C(B90+B180+B270+B360)+1.25*B360
计算得出C=1.742%
Swap Rate=1.742%*(360/90)=6.96%
但题目中写的swap rate 是5.56%,请问我的计算是哪里理解错了呢?
