问一道题：NO.PZ2019052801000050

  1. FRM I
  2. Financial Markets And Products

问题如下：

A US company entered into a one-year currency swap with quarterly reset six months ago. The notional principle is $1,000,000, At the swap’s initiation, the US company receives the notional amount in Australian dollars and pays to the counterparty the notional amount in US dollars. At the swap’s expiration, the US company pays the notional amount in Australian dollars and receives from the counterparty the notional amount in US dollars.The annual fixed swap rates for Australian dollars is 4% and for US dollars is 3.6%.The current spot exchange rate is A$1.2 / $ .

The US term structure is:

  • r(90)=3.58%

  • r(180)= 3.74%

The Australian term structure is:

  • r(90)=3.82%
  • r(180)= 4.1%

What is the value of the currency swap to US company?

选项：

A.

$-142,145million.

B.

$142,145million.

C.

$166 ,385.

D.

$-166 ,385.

解释：

C is correct.

考点：货币互换估值.

解析：

期初和期末美国公司收美元本金和利息的价值：

lB  $  =0.009e−0.0358×0.25+1.009e−0.0374×0.5=0.999227{l}B_{\;\$}\;=0.009e^{-0.0358\times0.25}+1.009e^{-0.0374\times0.5}\\=0.999227

期初和期末美国公司支澳大利亚元本金和利息的价值：

lB  A$  =0.01e−0.0382×0.25+1.01e−0.041×0.5=0.999411{l}B_{\;A\$}\;=0.01e^{-0.0382\times0.25}+1.01e^{-0.041\times0.5}\\=0.999411

lV=(0.999227−0.999411÷1.2)×1,0000,000=166,385{l}V=(0.999227-0.999411\div1.2)\times1,0000,000=166,385

请教为什么用连续复利啊。

这道题我用的单利，算出来都差异挺大的，然后答案还是连续复利。

同学你好！

一般规则是LIBOR为标的的时候用单利，比如intest swap、FRA，其他用复利。

有时是会不按照这个规则来，但是一般来说两种计算方法相差不是很大，在考试里不会大到影响做出正确选择的。
