NO.PZ2023091802000084

问题如下:

Given the following bonds and forward rates:

1-year forward rate one year from today = 9.56%

1-year forward rate two years from today = 10.77%

2-year forward rate one year from today = 11.32%

Which of the following statements about the forward rates, based on the bond prices, is true?

选项:

A.

The 1-year forward rate one year from today is too low.

B.

The 2-year forward rate one year from today is too high.

C.

The 1-year forward rate two years from today is too low.

D.

The forward rates and bond prices provide no opportunities for arbitrage.

解释:

1-year forward rate one year from today = 1.072/1.045 – 1 = 9.56%

1-year forward rate two years from today = 1.093/1.072 – 1 = 13.11%

2-year forward rate one year from today = (1.093/1.045)0.5 – 1 = 11.32%

同学你好,解析这个式子完全没有问题的啊。

拿你红框的这个位置来说,问的是1年以后1年期的forward rate,那就是拿2年的spot rate里面扣去第一年的spot rate
