Detailed Description

Abstract base class for inflation swaps.

Inflation swaps need two term structures: a yield curve, and an inflation term structure (either zero-based, i.e., the rate $ r(t) $ equals $ I(t)/I(t_0) - 1 $ where $ I $ if the index and $ t_0 $ is the base time, or year-on-year, i.e., $ r(t) = I(t)/I(t_p) - 1 $ where the previous time $ t_p $ is defined as $ t $ minus one year.)

Member Function Documentation

Date baseDate () const

The inflation rate is taken relative to the base date, which is a lag period before the start date of the swap.
