In this paper we review the pricing and model calibration of Credit Default Swaps referring to both the International Swaps and Derivatives Association (ISDA) CDS contract and credit model standardization guidelines. Furthermore we provide an Excel pricing workbook to supplement the materials discussed. The main goal is for this paper to act as a credit primer and to review the impact and purpose of ISDA contract and model standardization on credit pricing and modelling techniques.
We review the Credit Default Swap (CDS) product highlighting contract specifications, terminology and how the product has been standardized for increased liquidity and XVA capital cost reduction. We perform a fundamental review of probability and credit modelling, outlining standard market assumptions and techniques used by traders and other market practitioners. Furthermore we demonstrate how to price CDS contracts, calibrate credit models and discuss the ISDA Standard Model, ISDA Fair Value Model and Bloomberg Fair Value Models in particular. In conclusion we discuss CDS liquidity, the need for credit index proxies to hedge credit risk and outline liquidity alternatives to this such as the use of sector and index CDS contracts.
