Detailed Description

Coupon paying the performance of a CPI (zero inflation) index

The performance is relative to the index value on the base date.

The other inflation value is taken from the refPeriodEnd date with observation lag, so any roll/calendar etc. will be built in by the caller. By default this is done in the InflationCoupon which uses ModifiedPreceding with fixing days assumed positive meaning earlier, i.e. always stay in same month (relative to referencePeriodEnd).

This is more sophisticated than an IndexedCashFlow because it does date calculations itself.

Member Function Documentation

Rate baseCPI () const

base value for the CPI index


make sure that the interpolation used to create this is what you are using for the fixing, i.e. the observationInterpolation.
