What Is Credit Quality
Credit quality is one of the principal criteria for judging the investment quality of a bond or bond mutual fund. As the term implies, credit quality informs investors of a bond or bond portfolio's creditworthiness or risk of default. A company or security’s credit quality may also be known as its “bond rating."
- Credit quality is a measure of how likely a bond issuer is to repay its loan.
- A credit-quality rating can be assigned to an individual bond issuer or to a portfolio of bonds.
- Lower-rated bonds are more likely to default and, as such, must offer a higher yield.
Understanding Credit Quality
Credit quality is an important aspect of the credit markets. An individual bond or bond mutual fund's credit quality is determined by private independent rating agencies such as Standard & Poor's, Moody's, or Fitch, among others. Each rating agency has its own credit quality designations which typically range from high ('AAA' to 'AA') to medium ('A' to 'BBB') to low ('BB', 'B', 'CCC', 'CC' to 'C').
Credit rating agencies issue credit quality ratings for all types of issuers in the credit market. Factors that influence a corporate credit rating include the company’s capital structure, credit payment history, revenue, and earnings.
Credit quality ratings for developed-market countries, such as the United States, are typically on the higher end of the credit quality spectrum and promise investors investments with low risk of default. In the credit market, investment-grade ratings are typically perceived as high quality. Non-investment-grade bonds, also called high-yield or "junk" bonds, have lower credit quality and higher risk. Investment-grade bonds often have lower yields while non-investment grade bonds require higher yields to offset the greater risk.
Investors interested in the safety of their bond investments should stick to investment-grade bonds ('AAA', 'AA', 'A', and 'BBB'), while investors willing and able to accept a higher level of risk might consider lower credit-quality bonds with higher yields, if they believe for whatever reason that these borrowers with low credit are likely to repay.
