A LIBOR Market Model with Stochastic Basis
April 1, 2010
We extend the LIBOR market model to accommodate the new market practice of using different forward and discount curves in the pricing of interest-rate derivatives. Our extension is based on modeling the joint evolution of forward rates belonging to the OIS curve and corresponding spreads with FRA rates for different tenors.
We consider stochastic-volatility dynamics and address the related caplet and swaption pricing problems. We conclude the article with an example of calibration to real market data.
