All corporate bonds listed on the Moscow Exchange have a credit rating. In Russia, a national rating scale is used, where the highest rating is "AAA" and the lowest is "C". There is also a "D" category, which indicates a default. The higher the rating, the more reliable the issuer and, generally, the lower the yield on its bonds.
- **"AAA" bonds** are the most reliable. These are usually large systemically important companies, often with state participation.
- **Bonds rated from "A-" to "AA+"** are considered reliable. They are typically invested in by pension funds and other institutional investors.
- **Bonds rated from "BBB-" to "BBB+"** are transitional. These can be reliable companies that are sensitive to adverse market and economic events (e.g., an increase in the key interest rate).
- **Bonds rated from "B-" to "BB+"** are high-yield issuers (HY). The risks are high, as is the yield. These may be small or medium-sized businesses operating in risky sectors.
- **"CCC" and "D" rated bonds** are on the brink of default. The risks associated with these bonds are maximum.
