Moody’s Quiz: Inside Global Credit Decisions

Moody's has a history stretching back to the early twentieth century, making it one of the oldest credit assessment institutions in the world. It was founded at a time when investors had little structured information on the safety of railroad and industrial bonds, creating a clear need for independent credit analysis.

Moody's uses a distinct alphabetical notation system for its long-term ratings that differs from other major agencies. The top rating on this scale is given only to issuers with an exceptionally strong capacity to meet financial obligations. Moody's notation uses a mix of upper and lowercase letters, setting it apart visually.

The individual behind Moody's Investors Service was a financial publisher who identified a clear gap in the market for structured, accessible information on bond quality. He pioneered the idea of publishing manuals that assessed the safety of securities, a concept that was quite novel for bond investors at the time.

Moody's divides its rating scale broadly into two territories: investment grade and speculative grade. The boundary between the two is significant for institutional investors, many of whom are restricted from holding bonds below a certain threshold. The first speculative grade level signals a meaningful step up in overall credit risk.

Moody's uses a range of notations beyond its standard letter grades to communicate specific situations about a rated entity or instrument. Some notations are used when coverage of an issuer changes status rather than its creditworthiness. The 'WR' notation is one such designation that carries a specific administrative meaning.
