US Stocks Fall as Treasury Yields Hit 19-Year High

US stock markets declined from September 23 to 24, 2026, as the 10-year Treasury yield surged to 5.135%, the highest level since 2007. The selloff was triggered by S&P Global data showing US business activity at its strongest level in over five years, which investors interpreted as a signal that the Federal Reserve System has room to implement further interest rate hikes to combat stubborn inflation.

Federal Reserve Governor Michael Barr stated that inflation is not clearly trending toward the 2% target and that further policy adjustments are likely needed. These hawkish signals, combined with a weak five-year Treasury note auction, pushed yields higher and pressured tech stocks, including Nvidia. Simultaneously, Brent crude oil prices rose above $105 per barrel, driven by instability and threats from Iran to keep the Strait of Hormuz partially closed.

Corporate performance was mixed; while KB Home and General Mills reported stronger-than-expected profits, Stitch Fix shares tumbled over 22% due to a challenging consumer environment. In diplomacy, Treasury Secretary Scott Bessent announced that the United States and China agreed to extend their trade truce until January 10. This agreement preceded a high-stakes summit in Washington between President Donald Trump and President Xi Jinping to discuss trade, AI regulation, and the conflict in Iran.
