Fitch confirmed on Tuesday its triple-A rating of the United States, 10 days after rival Standard & Poor's dealt the country its first-ever downgrade due to its heavy debt burden.
"The affirmation of the US 'AAA' sovereign rating reflects the fact that the key pillars of US's exceptional creditworthiness remain intact: its pivotal role in the global financial system and the flexible, diversified and wealthy economy that provides its revenue base," Fitch Ratings said.
