| bool | indexIsInterpolated, | ||
| const QuantLib::DayCounter & | dayCounter = QuantLib::DayCounter() |
||
| ) |
Utility function for calculating the time to a given date based on a given inflation index, inflationIndex, and a given inflation term structure, inflationTs. An optional dayCounter can be provided to use instead of the inflation term structure day counter.

| QuantLib::Time | t, | ||
| const QuantLib::DayCounter & | dc, | ||
| bool | indexIsInterpolated | ||
| ) |
Utility for calculating the ratio \( \frac{P_r(0, t)}{P_n(0, t)} \) where \( P_r(0, t) \) is the real zero coupon bond price at time zero for maturity \( t \) and \( P_n(0, t) \) is the nominal zero coupon bond price.
| QuantLib::Real QuantExt::inflationGrowth | ( | const QuantLib::Handle< QuantLib::ZeroInflationTermStructure > & | ts, |
| QuantLib::Time | t, | ||
| bool | indexIsInterpolated | ||
| ) |
Utility for calculating the ratio \( \frac{P_r(0, t)}{P_n(0, t)} \) where \( P_r(0, t) \) is the real zero coupon bond price at time zero for maturity \( t \) and \( P_n(0, t) \) is the nominal zero coupon bond price.
| QuantLib::Real QuantExt::inflationLinkedBondQuoteFactor | ( | const QuantLib::ext::shared_ptr< QuantLib::Bond > & | bond | ) |
Calculate the Compound Factor to compute the nominal price from the real price I(t_s)/I(t_0) with I(t_s) the CPI at settlement date and I(t_0) the bond's base CPI
| std::map<std::tuple<std::string, QuantLib::CPI::InterpolationType, QuantLib::Frequency, QuantLib::Period>, QuantLib::ext::shared_ptr<QuantLib::ZeroInflationIndex> > QuantExt::extractAllInflationUnderlyingFromBond | ( | const QuantLib::ext::shared_ptr< QuantLib::Bond > & | bond | ) |
Iterates over all bond cashflows, and extract all inflation underlyings

| const QuantLib::Period | obsLag, | ||
| const QuantLib::Frequency | , | ||
| bool | interpolated | ||
| ) |
computes the fixingDate for ZC CPI Swap following the rule for an interpolated index it is d - obsLag but for an interpolated index the fixing date is per definition on the start of the inflation period in which d - obsLag falls

||
| ) |
Computes the base rate for curve construction so that zero inflation rate is constant up to the first pillar Accounts for the acctual accrued inflation between the ZCIIS base date and the curve base date (e.g. last published fixing date) If curve base date and ZCIIS are the same, then the base rate is the ZCIIS rate
| bool QuantExt::ZeroInflation::isCPIVolSurfaceLogNormal | ( | const QuantLib::ext::shared_ptr< QuantLib::CPIVolatilitySurface > & | surface | ) |
checks if the vols are normal or lognormal if the volsurface is not derived from QuantExt::CPIVolatilitySurface we default to lognormal vols
