The Comovements Of Stock, Bond, And Cds Illiquidity Before, During, And After The Global Financial Crisis

Using both marketwide and firm‐level illiquidity measures of the stock, bond, and credit default swap markets, we find that comovements of illiquidity across markets increase significantly during the recent global financial crisis. Moreover, the degree of comovement remains significantly higher in the postcrisis period and regulatory period than in the precrisis period. Specifically, the distribution of firm‐level comovements is notably different before and after the crisis (e.g., a much larger portion of firms with positive pairwise correlations between illiquidity measures in the postcrisis period than in the precrisis period). Our results provide suggestive evidence of the financial crisis effects and the subsequent postcrisis regulations on the comovements of illiquidity across markets.
