Speaker: Fabio Antonelli
Title: CVA and vulnerable options in stochastic volatility model
Abstract: CVA adjustment in order to evaluate correctly derivatives subject to default risk has become more and more important in the past decade, especially when Wrong Way Risk, that is an increase in the product's price when deterioration of credit occurs. Considering the most common stochastic volatility models, we express WWR in terms of the correlation between asset's price and default event, that is described exploiting the so called intensity approach. When intensity follows an affine process, we are able to parametrize this correlation and, applying accurately Ito's formula, to suggest a Taylor polynomial approximation of CVA. Some numerical results showing the efficiency of the method are provided.
Kind regards
