Abstract
In this study, I analyze the effect of central clearing on market liquidity in the CDS market. This study extends existing literature by using semi-parametric and non-parametric regression discontinuity designs (RDD) in order to isolate the effect of central clearing on measures of market tightness, market depth and market resiliency. I find evidence for a decrease in absolute bid-ask spreads with the beginning of central clearing and an increase in gross trading volume. Bid-ask spread resiliency decreases with the beginning of central clearing. These effect differ across contracts depending on their fundamental risk and liquidity risk. I show that counterparty risk and inventory costs may partly explain the effects of central clearing on CDS market liquidity. Especially the lower relevance of counterparty risk and lower regulatory capital charges seem to affect positively dealer competition and risk-taking capacity in the CDS market.
