Credit risk correlation and the cost of bank loans

Using several approaches to compute firms’ credit risk correlation, we provide robust empirical evidence that lenders charge higher loan spreads to borrowers with higher credit risk correlation. Consistent with the theoretical literature, we find that the credit risk correlation effect is concentrated in investment‐grade firms, driven by tightening lending conditions, and more pronounced for firms with higher rollover risk. We also show that banks whose borrowers have higher average credit risk correlation, have greater default risk themselves. Overall, our results indicate that banks view credit risk correlation as an important risk factor.
