Credit Market Shocks and Economic Fluctuations: Evidence from Corporate Bond and Stock Markets

To identify disruptions in credit markets, research on the role of asset prices in economic fluctuations has focused on the information content of various corporate credit spreads. We re-examine this evidence using a broad array of credit spreads constructed directly from the secondayr bond prices on outstanding senior unsecured debt issued by a large panel of nonfinancial firms. An advantage of our ``ground-up'' approach is that we are able to construct matched portfolios of equity returns, which allows us to examin the information contained in stock prices of the same set of firms, as well as in macroeconomic variables measuring economic activity, inflation, interest rates, and other financial indicators. Our portfolio-based bond spreads contain substantial predictive power for economic activity and outperform -- especially at longer horizons -- standard default-risk indicators. Much of the predictive power of corporate bond spread for economic activity is embedded in securities issued by intermediate-risk rather than high-risk firms. According to impulse responses from a structural factor-augmented vector autoregression, unexpected increases in bond spreads cause large and persistent contractions in economic activity. Indeed, shocks emanating from the corporate bond market account for more than 20 percent of the forecast error variance in economic activity at the two- to four-year horizon. Overall, our results imply that credit market shocks have contributed significantly to U.S. economic fluctuations during the 1990--2007 period.
