Sabr swaption model
WebThe SABR model Volatility cube Swaptions For example, a 2.50% 1Y !5Y (“1 into 5”) receiver swaption gives the holder the right to receive 2.50% on a 5 year swap starting in 1 year. More precisely, the option holder has the right to exercise the option on the 1 year anniversary of today (with the usual business day convention adjustments) in Webthe SABR model, which provides a way of interpolating volatilities between quoted strikes, as well as extrapolating beyond them. The SABR parameters (alpha, beta, rho and nu) can be easily calibrated when the market provides a number of reliable volatility quotes at different strikes, for a fixed expiry and tenor (see Skantzos et al. (2016)).

When a scenario (a Monte Carlo path) touches zero, we absorb it and set it to zero; that is why we call it “absorbing boundary SABR”. In our free boundary SABR model, we let the scenario (the path) crossing the zero boundary, without any absorption.
