Moody's on Friday changed the outlook on the government of United States of America's

Ratings to "negative" from "stable".
The rating agency said it expects United States' fiscal deficits will remain very large, significantly weakening debt affordability.

Moody's credit refers to Moody's Investors Service, one of the leading credit rating agencies in the world. Moody's provides credit ratings for various entities, including corporations, governments, and financial instruments, to assess their creditworthiness and ability to meet their financial obligations.

Moody's credit ratings are a measurement of the perceived credit risk associated with a particular entity or financial instrument. These ratings are assigned based on an analysis of various factors, including financial stability, debt levels, industry outlook, and macroeconomic conditions.

The credit ratings issued by Moody's are expressed as letter grades, ranging from AAA (highest quality) to C (lowest quality), with intermediate grades in between. For example, investment-grade ratings typically range from AAA to Baa, while speculative or non-investment-grade ratings range from Ba to C. The addition of a plus (+) or minus (-) sign further refines the ratings.

Moody's credit ratings are widely used by investors, organizations, and governments to assess the creditworthiness and risk associated with potential investments, loans, or financial transactions. These ratings provide valuable information and help market participants make informed decisions by evaluating the default risk and the potential return on investment.

It's important to note that credit ratings are opinions and not guarantees of future performance. They are based on the information available at the time of the rating and can change over time as new information becomes available.
