Numerical analysis of an extended structural default model with mutual liabilities and jump risk

We consider a structural default model in an interconnected banking network as in [1], with mutual obligations between each pair of banks. We analyse the model numerically for two banks with jumps in their asset value processes. Specifically, we develop a finite difference method for the resulting two-dimensional partial integro-differential equation, and study its stability and consistency. We then compute joint and marginal survival probabilities, as well as prices of credit default swaps (CDS), first-to-default swaps (FTD), Credit and Debt Value Adjustments (CVA and DVA). Finally, we calibrate the model to market data and assess the impact of jump risk.
