Market-implied rating
(Redirected from Market Implied Ratings)
A market-implied rating estimates the market observed default probability of an individual, corporation, or even a country. Indeed, a credit rating is simply a probability of default.[1] The methodology used by Moodys consists in a median piecewise fit of the ratings to the credit defaut swap data observed on the market.[2] S&P however uses a log regression between the log cds and the ratings equivalent number, adjusted to firm specifics, continent, and outlook.[3][4]
