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 peicewise 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 ot firm specifics, continent, and outlook. ^{[3] [4]}
