The S&P 500 fell on Tuesday as rising bond yields and oil prices reduced demand for technology stocks. Semiconductor shares led the losses, while energy and defensive sectors attracted buyers.
The S&P 500 dropped about 0.5% during early trading. The NASDAQ Composite lost roughly 1.2%, while the Dow traded near flat before moving lower.

High bond yields can reduce the present value of expected company earnings. They also raise financing costs for technology companies spending heavily on artificial intelligence infrastructure.
The 30-year Treasury yield climbed above 5.3% and reached its highest intraday level since 2007. Meanwhile, the 10-year Treasury yield rose to about 4.74%.
Government bond yields also increased outside the United States. Japan’s 10-year yield reached a 30-year high. Germany’s 30-year yield climbed to its highest level since 2011.
France’s 30-year government bond yield also reached its highest point since 2008. Investors monitored government borrowing, fiscal spending, inflation risks, and growing debt demand from AI companies.
Kim Forrest, chief investment officer at Bokeh Capital Partners, said, “The yields are troubling people because it portends a tighter environment.” She added that higher rates make borrowing more expensive.
Peter Boockvar of One Point BFG Wealth Partners questioned how long stocks could ignore the bond selloff. He said, “It’s just a matter of when, not if,” markets respond if yields keep rising.

Higher oil prices added to inflation concerns and supported energy shares. The S&P 500 Energy sector gained 1.4%, contrasting with losses across technology and semiconductor companies.
Investors moved toward healthcare and consumer staples stocks during the market decline. These sectors often attract demand when volatility increases and growth shares weaken.
