The United States has just lost its last perfect credit rating, a significant downgrade that could have serious implications for financial markets and the broader economy. On Friday, Moody’s Ratings downgraded U.S. government debt, stripping the country of its long-held AAA rating. This move marks the end of more than a century of top-tier credit status with Moody’s, which had maintained its AAA rating on U.S. debt since 1917.
Moody’s was the final of the “Big Three” credit rating agencies—alongside S&P Global and Fitch—to maintain a perfect rating for U.S. debt. Its downgrade signals a deepening concern over America’s long-term fiscal outlook, including rising deficits, unsustainable debt levels, and persistent political dysfunction that threatens the government’s ability to manage its finances responsibly.
This loss of confidence could rattle global markets, increase borrowing costs for the U.S. government, and put upward pressure on interest rates across the economy—from mortgages and student loans to credit cards and business loans. In turn, it may further complicate the Federal Reserve’s efforts to manage inflation and stabilize the economy.
While the downgrade doesn’t suggest an imminent risk of default, it does reflect growing doubts about the long-term fiscal credibility of the United States—and that could have lasting consequences.
