问题如下:
A one-year zero-coupon bond yields 4.0%. The two- and three-year zero-coupon bonds yield 5.0% and 6.0% respectively.
The rate for a one-year loan beginning in one year is closest to:
选项:
A.4.5%
B.5.0%.
C.6.0%.
解释:
C is correct.
From the forward rate model. we have
[1+r(2)]2=[1+r(1)]1[1+f(1,1)]1
Using the one- and two-year spot rates. we have
(1+0.05)2=(1+0.04)1[1+f(1,1)]1so (1+0.04)1(1+0.05)2−1=f(1,1)=6.010%
请问这道题用不用先用Par rate算Spot rate呢?
