问题如下:
A corporate bond offers a 5% coupon rate and has exactly 3 years remaining to maturity. Interest is paid annually. The following rates are from the benchmark spot curve:
The bond is currently trading at a Z-spread of 234 basis points. The value of the bond is closest to:
选项:
A.92.38.
B.98.35.
C.106.56.
解释:
A is correct.
The value of the bond is closest to 92.38. The calculation is:
考点:bond valuation
解析:由于本题给了Z-spread,所以要在各年的Spot rate基础上再加上Z-spread,才是这只债券现金流的对应折现率。第一年现金流(5)用折现率(7.2%)折现,第二年现金流(5)用折现率(7.29%)折现,第三年现金流(5+100)用折现率(7.99%)折现,通过现金流折现求和,可得债券价格为92.38,故选项A正确。
老师你好,如果按照题目的解法,1 year 是4.86+spread;1-2 year是4.95+spread;2-3 year是5.65+spread,那这样spot rate的含义看起来就跟forward rate一样了呢?
我本来以为spot rate就是从开始到t时刻的零息利率,比如4.86就是0-1 year的rate,4.95就是0-2 year的rate,5.65就是0-3 year的rate。麻烦老师解释一下,谢谢。
