Moody's lowers US credit outlook, though keeps triple-A rating

WASHINGTON — The credit rating agency Moody’s Investors Service lowered its outlook on the U.S. government's debt on Friday to “negative” from “stable,” citing the cost of rising interest rates and political polarization in Congress.

Moody's retained its top triple-A credit rating on U.S. government debt, though it is the last of the three major credit rating agencies to do so. Fitch Ratings lowered its rating to AA+ from AAA in August, and Standard & Poor's downgraded the U.S. in 2011. A reduced outlook, however, raises the risk that Moody's could eventually strip its triple-A rating from the U.S. as well.

A lower rating on U.S. debt could cost taxpayers if it leads borrowers to demand higher interest rates on Treasury bills and notes. The yield on the 10-year Treasury has risen significantly since July, from about 3.9% to 4.6% Friday, an unusually sharp rise.

Some market analysts have said the August Fitch downgrade may have contributed to that increase, though most point to other factors as bigger drivers, such as the Federal Reserve's commitment to keeping its benchmark rate at a 22-year high to battle inflation.

“In the context of higher interest rates, without effective fiscal policy measures to reduce government spending or increase revenues, Moody’s expects that the U.S.'s fiscal deficits will remain very large, significantly weakening debt affordability,” the agency said in a statement.

The Biden administration criticized Moody's decision.

“While the statement by Moody’s maintains the United States’ Aaa rating, we disagree with the shift to a negative outlook,” Deputy
