老师,对Future Price公式里的FVC还是有点困惑,图1中因为at contract expiration时no coupon payment,所以FVC=0,这个FVC可以理解为是contract expiration时的coupon吗?图二中AI over life of future contract=0,所以FVC=0,FVC与AI的关系又是怎样的?

你好,FVC是期货持有期间收到的票息,复利到合约结束时的价值,公式为FVC = coupon*(1+rf)^t。而AI是应计利息,是债券自上一次付息后累计未付的利息AIt=coupon*t/T。课后题和讲义上这种题刚好又都是FVC=0时的情况,可以参考下面这题,涉及到FVC的计算。
Moyle provides Petsas and Iacocca with the following information for a Treasury bond and asks them to calculate the price of a futures contract on this bond. The bond has a face value of $100,000, pays a 7% semiannual coupon, and matures in 15 years. The bond is priced at $156,000 and yields 2.5%. The bond has just paid the coupon. The futures contract expires in eight months, and the annualized risk-free rate is 1.5%. There are multiple deliverable bonds, and the conversion factor for this bond is 1.098.
QFP=(𝑆0×(1+𝑅f )^𝑇−𝐹𝑉𝐶-AIT)/CF,其中𝑆0=156,000,𝑅f=1.5%,𝑇=8/12, FVC=coupon*(1+𝑅f)^t=100,000*7%/2*(1+1.5%)^2/12 (FVC是6时点的coupon复利到8时点,共2个月,因此t=2/12),AIT=coupon*2/6=3500/3=1166.67(AIT是6到8时点应计利息,共2月,占半年利息的2/6)。
