Having a lot of trouble with this one.
Vol. 5 page161 says the swap rate is a weighted average of the component forward rates.
However, page 144 goes to great lengths to explain that the swap rate is NOT an average of forward rates because of the benefit of receiving greater amounts early in the term.
I can't figure out the difference. Anyone help?作者: Unforseen 时间: 2011-7-11 20:06
Oh ok I think I get that. So you take the pv of the forward rates and that determines the weights?
Thanks, that pulls everything together.作者: Darien 时间: 2011-7-11 20:06
Actually, it's more intuitive than what is in L2 formula. It's basically stating that the pv(receiv floating leg cash flows)=pv(pay fixed leg cash flows).
Forwards determine the "future" cash flow payments in receive floating leg.
Swap rate, the fixed rate, can be derived from the above equation.
