为什么本题不适用重新定价法？

问题如下：

A bank entered into a 3×6 FRA 30 days ago as a fixed receiver. The fixed rate is 1.25%, and notional principle is $100 million. The settlement terms are advanced set, advanced settle. The current Libor data is as follows:

The value of this 3×6 FRA is:

选项：

11,873

-11,873

-12,579

解释：

B is correct.

考点：FRA的估值

解析：

画图：

$value_{long}=\frac{100000000}{1+1.05\%\times\frac{60}{360}}-\frac{100000000\times(1+1.25\%\times\frac{90}{360})}{1+1.2\%\times\frac{150}{360}}=11873$

题中的银行是fixed receiver，即FRA的short方。上图是以Long方，即Borrower(floating receiver）为例，所以fixed receiver (short)的value=-long=-11873

参考了下其他同学提的问题，看到有老师回答说本题不适用重新定价法，原因是什么？

（基础班讲义P40的例题，老李老师也是用的重新定价法讲的）

嗨，从没放弃的小努力你好：

重新定价法一般会给出当前时点新签合约的价格，本题不是不适用，是从考试计算速度角度考虑，上减下的方法会更快一些
