Wall Street experienced a significant downturn on Tuesday as rising oil prices and persistent inflation fears drove bond yields higher, negatively impacting stocks. The S&P 500 fell 0.5%, while the Dow Jones Industrial Average dropped 105 points, or 0.2%. The Nasdaq composite saw the steepest decline, falling 0.9%.

Technology stocks were particularly affected, with Nvidia down 1.1% and Micron Technology falling 2.2%. This pressure stems from an ongoing sell-off in U.S. government bonds, pushing the 10-year Treasury yield to 4.76% from 4.75% on Monday. Higher bond yields indicate increased investor demand for returns due to perceived higher risk, partly driven by the U.S. debt surpassing $40 trillion two weeks prior, a significant milestone.

A major contributor to inflation and market pressure was the rise in oil prices. Brent crude, the international standard, increased by 2% to $92.33 per barrel. This surge is largely attributed to ongoing U.S. conflict with Iran, which has disrupted shipping through the Strait of Hormuz, a crucial oil transit route. High energy costs have fueled inflation, which remains well above the Federal Reserve's 2% target, leading Wall Street to anticipate a rate hike before year-end to curb price increases. Higher borrowing costs resulting from rising bond yields are expected to dampen investments and make business expansion more challenging.
