The Economics of Credit Default Swaps (CDS)

Credit default swaps (CDS) are term insurance contracts written on traded bonds. This paper studies the economics of CDS using the economics of insurance literature as a basis for analysis. It is alleged that trading in CDS caused the 2007 credit crisis, and therefore trading CDS is an "evil" which needs to be eliminated or controlled. In contrast, we argue that the trading of CDS is welfare increasing because it facilitates a more optimal allocation of risks in the economy. To perform this function, however, the risk of CDS seller failure needs to be minimized. In this regard, government regulation imposing stricter collateral requirements and higher equity capital for CDS traders need to be imposed.
