Focusing on recent advances in option pricing under the SABR model, this
book shows how to price options under this model in an arbitrage-free,
theoretically consistent manner. It extends SABR to a negative rates
environment, and shows how to generalize it to a similar model with
additional degrees of freedom, allowing simultaneous model calibration
to swaptions and CMSs.
Since the SABR model is used on practically every trading floor to
construct interest rate options volatility cubes in an arbitrage-free
manner, a careful treatment of it is extremely important. The book will
be of interest to experienced industry practitioners, as well as to
students and professors in academia.
Aimed mainly at financial industry practitioners (for example quants and
former physicists) this book will also be interesting to mathematicians
who seek intuition in the mathematical finance.
