Bridgewater Associates founder and billionaire Ray Dalio warned Monday that Moody’s downgrade of the U.S. sovereign credit rating understates the threat to U.S.

Moody’s Investors Service downgraded the U.S. sovereign credit rating from Aaa to Aa1, marking the first time all three major credit rating agencies—Moody’s, S&P, and Fitch—have rated U.S. debt below the top tier.

If the U.S.’s loss of its final perfect credit rating boosts yields on Treasury debt, it likely would boost the cost of borrowing for both companies and consumers.

Investors largely shrugged off a downgrade of the U.S.'s credit rating in Monday trading as stocks ended the day mostly flat.

American markets fell to open the week Monday, reacting to Saturday's news that Moody's Ratings was downgrading U.S. debt.

U.S. Treasury Secretary Scott Bessent warned Sunday that some of America’s trading partners could soon face a sharp hike in tariff rates, and dismissed Moody’s downgrade of the U.S. government’s credit rating.
