Credit ratings are formal assessments provided by specialized agencies to evaluate the creditworthiness of an entity. These evaluations are crucial for investors, financial institutions, and market participants to determine the probability of default by the entity, which can be a corporation, government, or financial instrument. Major credit rating agencies include Moody’s Investors Service, Standard & Poor’s (S&P), and Fitch Ratings.

Credit ratings are influenced by several factors and encapsulate various evaluations, including:
- Economic Environment
