Moody's downgrades United States credit rating on increase in government debt

Moody’s Ratings cut the United States’ sovereign credit rating down a notch to Aa1 from the Aaa, the highest possible, citing the growing burden of financing the federal government’s budget deficit and the rising cost of rolling over existing debt amid high interest rates.

Moody’s Ratings cut the United States’ sovereign credit rating down a notch to Aa1 from the Aaa, the highest possible, citing the growing burden of financing the federal government’s budget deficit and the rising cost of rolling over existing debt amid high interest rates.

“This one-notch downgrade on our 21-notch rating scale reflects the increase over more than a decade in government debt and interest payment ratios to levels that are significantly higher than similarly rated sovereigns,” the ratings agency said in a statement.

The decision to lower the United States credit profile would be expected, at the margin, to lift the yield that investors demand in order to buy U.S. Treasury debt to reflect more risk, and could dampen sentiment toward owning U.S. assets, including stocks. That said, all the major credit rating agencies continue to give the United States their second-highest available rating.

The yield on the benchmark 10-year Treasury note climbed 3 basis points in after-hours trading, trading at 4.48%. The iShares 20+ Year Treasury Bond ETF fell about 1% in extended trading, while the SPDR S&P 500 ETF Trust fell 0.4%.

Standard & Poor’s downgraded the U.S. to AA+ from AAA in August 2011, and Fitch Ratings also cut the U.S. rating to AA+ from AAA, in August 2023.
