Fitch reaffirms U.S.'s AAA rating

“The affirmation of the US ‘AAA’ sovereign rating reflects the fact that the key pillars of US’s exceptional creditworthiness remains intact: its pivotal role in the global financial system and the flexible, diversified and wealthy economy that provides its revenue base,” Fitch said in its statement.

“Monetary and exchange rate flexibility further enhances the capacity of the economy to absorb and adjust to ‘shocks’.”

However, Fitch warned the outlook for the rating depended on the economy and the political process in Washington to reduce the public debt.
