问题如下:
If spot rates are as follow, what are par rates for one, two, and three years with semi-annual compounding?
解释:
The one-year par rate is
2×100×(1-0.965898) / (0.985222+ 0.965898)=3.4957
Similarly, the two and three-year par rates are 3.9871% and 4.1822%.
题目问:已知半年付息一次的不同期限的spot rate,求1,2,3年期的半年付息一次的par rate。
半年的 discount factor = 1/(1+3%/2)=0.985222
一年的 discount factor = 1/(1+3.5%/2)2 =0.965898
1 年par rate/2 * 0.985222 + (1年par rate/2+100) * 0.965898 = 100
一年期的par rate=3.4957
同理计算出
2年的par rate=3.9871%
3年的par rate=4.1822%.
