Fitch Ratings is one of the three major global credit rating agencies, alongside Moody's and S&P. It provides credit ratings, research, and analysis on bonds, sovereign debt, and financial institutions, which significantly influence borrowing costs and market sentiment.
Example
“When Fitch downgraded U.S. government debt from AAA to AA+, the news sent shockwaves through bond markets and briefly pushed Treasury yields higher as investors reassessed credit risk.”
