分子上面3/12是什么?

NO.PZ2019052801000033

问题如下:

Consider the following 6×9 FRA, Assume the buyer of the FRA agrees to a contract rate of 6.35% on a notional amount of 10 million USD. Assume a 30/360 day count basis. What is the settlement amount of the seller if the settlement rate is 6.85%?

选项:

A.

-$12,290.

B.

$12,290.

C.

-$12,500.

D.

$12,500.

解释:

A is correct.

考点:Forward Rate Agreement

解析:

10m×(6.35%6.85%)×3/121+6.85%×3/12=12,290\frac{10m\times(6.35\%-6.85\%)\times3/12}{1+6.85\%\times3/12}=12,290

这里要注意一个陷阱,因为题目最后问的是seller,所以应该是-12,290。

我在t=9时刻 (6.85%-6.35%)x 10million 就是这个时刻的现金流

再折算到t=6时刻 就是乘以1/(1+6.85%x3/12)这才settement 啊。答案分子上面乘以3/12是什么意思?三观给我惊掉了

嗨,爱思考的PZer你好:


题目说 the following 6×9 FRA,意思是FRA的持续期是3个月。

题目给出的利率都是年化利率(12个月的),意思是假设1年的时间,才有6.38-6.85这么多的利息,但是FRA持续期只有3个月,所以要对分子的年化利率乘以3/12。
