Bond credit rating assesses the creditworthiness of debt securities issued by enterprises or economic entities. Most bond credit ratings pertain to corporate bonds, evaluating the reliability of a specific bond issued by an independent legal entity in repaying principal and interest on schedule, while indicating its creditworthiness level. Such ratings provide informational services for investors purchasing bonds and for secondary market trading activities. Treasury bonds issued by the national treasury and financial bonds issued by state-owned banks are exempt from credit rating due to government guarantees. However, securities issued by local governments or non-state financial institutions generally require credit assessment.
Credit rating agencies conducting credit ratings for publicly issued corporate bonds shall comply with the following regulations or requirements:
- Disclose rating information to the issuer and promptly release initial rating reports, periodic tracking rating reports, and ad-hoc tracking rating reports to the market;
- For corporate bonds with a maturity exceeding one year, release a periodic tracking rating report to the market at least annually throughout the bond’s valid existence;
- Diligently monitor all significant factors potentially affecting the credit rating of the rated entity, promptly announce credit rating adjustments and other rating-related changes to the market, and report such changes to the securities exchanges.
