问题如下:
An investor has collected the below data of three bond:
According to the information, what is the 2-year and 3-year spot rates using the bootstrapping method?
选项:
A.
B.
C.
D.
解释:
C is correct.
考点:Interest Rate
解析:首先确定三个债券的现金流情况
Bond 1 -$94.3396+$100
Bond 2 -$96.3897 +$5 +$105
Bond 3 -$94.8458 +$6 +$6 +$106
我们可以直接知道1-year 的即期利率Z1=6%
根据债券的定价公式来确定2-year 的即期利率Z2:
$96.3897= $5/1.06 + $105/ (1+ Z2)^2 , 所以Z2 =7.02%
再根据第一年和第二年的即期利率,确定3-year的即期利率Z3:
$94.8458= $6/1.06 + $6/1.0702^2 + $106 /(1+ Z3)^3 , 所以Z3 =8.09%
此题是否默认债券面值是100?感觉缺了一个条件。
