. These individual codes are grouped into broader classes described as "investment grade" or not, or in numbered tiers from high to low. In addition to the rating codes, agencies typically supplement the current assessment with indications of the chances for future upgrades or downgrades over the medium term. For example, Moody's designates an ''Outlook'' for a given rating as Positive (POS, likely to upgrade), Negative (NEG, likely to downgrade), Stable (STA, likely to remain unchanged), or Developing (DEV, contingent on some future event).

, the so-called "Big Three" credit rating agencies. Generally they are bonds that are judged by the rating agency as likely enough to meet payment obligations that banks are allowed to invest in them. Ratings play a critical role in determining how much companies and other entities that issue debt, including sovereign governments, have to pay to access credit markets, i.e., the amount of interest they pay on their issued debt. The threshold between investment-grade and speculative-grade ratings has important market implications for issuers' borrowing costs. Bonds that are not rated as investment-grade bonds are known as high yield bonds or more derisively as

junk bonds In finance, a high-yield bond (non-investment-grade bond, speculative-grade bond, or junk bond) is a bond that is rated below investment grade by credit rating agencies. These bonds have a higher risk of default or other adverse credit events ...

Criticism

Until the early 1970s, bond credit ratings agencies were paid for their work by investors who wanted impartial information on the credit worthiness of securities issuers and their particular offerings. Starting in the early 1970s, the "Big Three" ratings agencies (S&P, Moody's, and Fitch) began to receive payment for their work by the securities issuers for whom they issue those ratings, which has led to charges that these ratings agencies can no longer always be impartial when issuing ratings for those securities issuers. Securities issuers have been accused of "shopping" for the best ratings from these three ratings agencies, in order to attract investors, until at least one of the agencies delivers favorable ratings. This arrangement has been cited as one of the primary causes of the

subprime mortgage crisis The United States subprime mortgage crisis was a multinational financial crisis that occurred between 2007 and 2010 that contributed to the Financial crisis of 2007–2008, 2007–2008 global financial crisis. It was triggered by a large decline ...

. Until April–May 2010, Moody's and Fitch were rating municipal bonds on the separate naming/classification system which mirrored the tiers for corporate bonds. S&P abolished its dual rating system in 2000.

Default rates

The historical default rate for municipal bonds is lower than that of corporate bonds. A potential misuse of historic default statistics is to assume that historical average default rates represent the "
