This paper analyzes the CDS spread development during the time a firm’s credit rating is under review. We test whether rating agencies take on a monitoring type role with regard to firms’ credit risk, thereby offering significant benefits and new information to market participants during the rating review process.

These results underline the importance of monitoring by rating agencies for credit risk valuations.
