Options on Bonds: Implied Volatilities from Affine Short-Rate Dynamics

Mathematical Finance 2021-06-09 v1

Abstract

We derive an explicit asymptotic approximation for the implied volatilities of Call options written on bonds assuming the short-rate is described by an affine short-rate model. For specific affine short-rate models, we perform numerical experiments in order to gauge the accuracy of our approximation.
