Low Strike Extrapolation for SABR - d-fine
Sebastian Schlenkrich, André Miemiec, Tilman Wolff-Siemssen, d-fine GmbH, Frankfurt, Germany

In this paper we analyse the modelling of rate options in a low interest rate market environment. In particular, the pricing of low, zero and negative strike vanilla options is considered. We review the modelling approaches available in the literature. For the important special case of the widely used SABR formula we illustrate the shortcomings connected with the low strike wing of the smile.

Moreover, a simple approach of low strike extrapolation will be presented. It is based on gluing the density function implied by the standard SABR formula to a suitable density function at low strikes in an arbitrage free manner. This approach yields a robust and transparent method to price low, zero and negative strike vanilla options.
