After Moody’s downgraded the U.S. credit rating from Aaa to Aa1, investors sold off government bonds, driving long-term Treasury yields sharply higher. This spike in yields raises borrowing costs for consumers and businesses alike, potentially slowing economic growth. 

Analysts warned that higher rates could ripple across mortgages, auto loans, and business financing, putting pressure on spending and investment. While credit downgrades by S&P and Fitch in past years had limited long-term economic impact, the timing of Moody’s move—amid heightened bond market volatility and mounting national debt—has amplified market anxiety. 

Some experts view the downgrade as a long-anticipated but symbolically important warning about unsustainable fiscal trends. Still, markets showed resilience, with equities rebounding by midday and Treasury yields pulling back slightly from their highs.
