Hi all, I am trying to price inflation
cap and floor using YoYInflationBlackCapFloorEngine and there is something not
really clear to me. The NPV of an inflation
floor with zero floor rate is always zero whatever volatility and for any term.
Of course market quotes are not zero. I think this is due to applying
the Black formula with the forward = I(T)/I(T-1)-1 and strike = floor rate,
instead of forward = I(T)/I(T-t) and strike=1+floor rate. In the latter case
you can get a non zero npv. Thanks for your help.
