Bond credit rating refers to the credit assessment conducted on valuable bonds issued by enterprises or economic entities. Most bond credit ratings pertain to corporate bonds, involving the evaluation of reliability in timely repayment of principal and interest for specific bonds issued by legally independent enterprises, with corresponding credit grade classifications. This credit rating mechanism provides informational services for investors purchasing bonds and facilitates secondary market circulation activities. Treasury bonds issued by national fiscal authorities and financial bonds issued by state banks are exempt from credit ratings due to government guarantees, while securities issued by local governments or non-state financial institutions generally require rating assessments.

  Credit rating agencies conducting ratings for publicly issued corporate bonds must comply with the following regulations:

• Disclose rating information to issuers and promptly release initial rating reports, periodic and ad-hoc follow-up rating reports to the market;
• For corporate bonds with maturities exceeding one year, publish annual follow-up rating reports at least once during the bond's valid duration;
• Diligently monitor all material factors affecting credit ratings, promptly disclose credit rating adjustments and related information changes to the market, and report to securities exchanges.
