问题如下:

Based on Exhibit 6 and the three-month US dollar Libor at expiration, the payment amount that the bank will receive to settle the 6 x 9 FRA is closest to:

选项:

A.

$19,945.

B.

$24,925.

C.

$39,781.

解释:

A is correct.

Given a three-month US dollar Libor of 1.10% at expiration, the settlement amount for the bank as the pay-fixed (receive-floating) party is calculated as

Settlement amount pay-fixed (receive floating)

= NA × {[Lm – FRA0 ]tm }/[1 + Dm tm ]}.

Settlement amount pay-fixed (receive floating)

=$20,000,000 × {[0.011 – 0.0070] × (90/360)]/[1 + 0.011(90/360)]}.

Settlement amount pay-fixed (receive floating)

=$20,000,000 × (0.001)/1.00275 = $19,945.15.

中文解析:

本题考察的是在FRA到期时刻求value。仍然使用画图法。

向上箭头为:NP

向下箭头为:NP×[1+0.7%×90360]1+1.1%×90360\frac{NP\times\left[1+0.7\%\times{\displaystyle\frac{90}{360}}\right]}{1+1.1\%\times{\displaystyle\frac{90}{360}}}

令向上箭头-向下箭头得到此时的value,其中NP=20,000,000

分母时间是不是错了,是不是不应该是180天

嗨,从没放弃的小努力你好:


根据题目条件,这个FRA合约是90天之前签订的:

也就是现在已经是t=90天的时刻了,而FRA到期日是t=180天,所以从现在到FRA到期日之间还剩90天的时间。所以是90/360。
