Efficient Calibration and Pricing in LIBOR Market Models with SABR Stochastic Volatility Using GPUs

open access: green, 2016
In order to overcome the drawbacks of assuming deterministic volatility coefficients in the standard LIBOR market models, several extensions of LIBOR models to incorporate stochastic volatilities have been proposed. The efficient calibration to market data of these more complex models becomes a relevant target in practice.

On an Extension Multifractional SABR Model for Pricing Variance and Volatility Swaps

open access: diamondAsian Journal of Probability and Statistics
This paper presents a robust methodology for the valuation of options on variance swaps and volatility swaps. While existing literature has often focused on the pricing of the swaps themselves under stochastic volatility models, the valuation of options on these second-order derivative products remains a challenge, particularly within a framework that ...

The SABR Model : Calibrated for Swaption's Volatility Smile

open access: green, 2014
Problem: The standard Black-Scholes framework cannot incorporate the volatility smiles usually observed in the markets. Instead, one must consider alternative stochastic volatility models such as the SABR. Little research about the suitability of the SABR model for Swedish market (swaption) data has been found.

Extension of SABR Libor Market Model to handle negative interest rates

open access: yesQuantitative Finance and Economics, 2020
Variations of Libor Market Model (LMM), including Constant Elasticity of Variance-LMM (CEV-LMM) and Stochastic Alpha-Beta-Rho LMM (SABR-LMM), have become popular for modeling interest rate term structure.
