Back-of-the-envelope swaptions in a very parsimonious multicurve interest rate model
arXiv:1712.06466
Abstract
We propose an elementary model to price European physical delivery swaptions in multicurve setting with a simple exact closed formula. The proposed model is very parsimonious: it is a three-parameter multicurve extension of the two-parameter Hull-White (1990) model. The model allows also to obtain simple formulas for all other plain vanilla Interest Rate derivatives. Calibration issues are discussed in detail.
