Liquidity Premia in the Credit Default Swap and Corporate Bond Markets

摘要

This paper employs a new approach to estimating the size of liquidity premia in the credit default swap (CDS) and corporate bond markets. We develop a CDS pricing model with liquidity and default, and a corporate bond pricing model with default, taxes, and liquidity using the reduced-form approach, and jointly estimate parameters of both pricing models from pooled data using the generalized method of moments. By formulating default intensity as a common factor of the spreads of the CDS and reference bonds, we are able to identify the liquidity and other components of spreads more precisely. We find that both CDS and corporate bond spreads contain significant liquidity components. On average, the liquidity premium accounts for 13% of the CDS spread and 23% of the corporate yield spread. The size of the liquidity premium increases as the rating decreases. Estimates of liquidity premia in the CDS and corporate bond markets are highly correlated, and closely linked to bond-specific and aggregate liquidity measures. Results show that liquidity is important for CDS and corporate bond pricing. Ignoring CDS illiquidity results in a significant bias in estimation of corporate yield spread components when using the CDS information to aid in decomposition of spreads.
