A bond rating agency is a company that specializes in evaluating the credit risk of debt securities issued by various entities, including corporations, municipalities, and governments. These agencies assign ratings to bonds based on the issuer’s financial stability, ability to meet debt obligations, and overall creditworthiness. The ratings help investors assess the risk of default associated with the bonds and make informed investment decisions.
