The spot interest rates are follows: one year, 3.5%; two years, 4.5%. Toy is the reset y, the current value of the sw is closest to: A.$54,437. B.$-54,437. C.-$30,125. $30,125. B is correct.考点利率互换估值.解析支浮动的一方可以看作一个浮动利率债券，浮动利率债券在reset y 价值回归面值。收固定的一方可以看作一个固定利率债券，Bfix  =0.04e−0.035+1.04e−0.045×2=0.989113B_{fix}\;=0.04e^{-0.035}+1.04e^{-0.045\times2}\\=0.989113Bfix​=0.04e−0.035+1.04e−0.045×2=0.989113lV=(0.989113−1)×5,000,000=−54,437{l}\\V=(0.989113-1)\times5,000,000=-54,437lV=(0.989113−1)×5,000,000=−54,437 比如，本题是floating payer，最终是用计算出的fix现金流的现值-面值1，为什么不是用1-fix现值呢，谢谢
