Credit ratings are conducted by agencies to evaluate the creditworthiness of individuals, corporations, and countries. The rating process involves analyzing financial history, current assets and liabilities, as well as country risk, business risk, industry factors, and financial risk. Higher credit ratings indicate a lower probability of default and allow borrowers to access loans at lower interest rates. In India, major credit rating agencies include CRISIL, ICRA, CARE, and Fitch Ratings India.
