问题如下:
From the bank’s perspective, using data from Exhibit 1, the current value of the swap described in Exhibit 2 is closest to:
选项:
A.-$2,951,963.
-$1,849,897.
-$1,943,000.
解释:
B is correct.
The value of a swap from the perspective of the receive-fixed (pay floating) party is calculated as
The swap has two years remaining until expiration. The sum of the present values for Years 1 and 2 is
Given the current equilibrium two-year swap rate of 1.12% and the fixed swap
rate at initiation of 3.00%, the swap value per dollar notional is calculated as
V = 1×(0.03 – 0.0112) x 1.967975 = 0.036998
The current value of the swap, from the perspective of the receive-fixed party, is
$50,000,000 × 0.036998 = $1,849,897.
From the perspective of the bank, as the pay-fixed party, the value of the swap
is –$1,849,897.
中文解析:
本题是考察的是用重新定价法来求value。
对于本题中付固定端的一方,在利率上升时会有收益。
根据题干信息可知FS0=3%,即0时刻签订此合约,价格为3%,但过了一年后合约的价格为FS1=1.12%。即价格下跌了,因此会有损失,最后的结果为负。
另外注意折现因子的选取要注意使用的是1年和2年的折现因子,因为此时站在t=1时刻,还有两笔互换要发生,分别是在一年以后和两年以后,因此折现因子的选取要注意。
最后根据公式:
带入即可求得t=1时刻的价值。
T=3,现在t=1时刻,向下箭头往t时刻折现的时候为什么用的折现因子还是表1里面的1年和2年的折现因子?表格里的1/2/3年的折现因子不是t=0时刻的吗?
