NEW YORK, New York - U.S. equity markets closed sharply lower on Wednesday, dragged down by a surge in Treasury yields that weighed on growth and technology shares, while oil prices soared as hostilities continued to flare in the Gulf, stoking fresh inflation concerns.

The broad-based selloff hit all three major U.S. indexes. The Standard and Poor's 500 fell 37.04 points, or 0.48 percent, to close at 7,636.48, with trading volume reaching 2.642 billion shares.

The blue-chip Dow Jones Industrial Average suffered steeper losses, dropping 405.05 points, or 0.77 percent, to finish the session at 52,381.02 on volume of 392.492 million shares.

The tech-heavy NASDAQ Composite declined by 168.07 points, or 0.64 percent, ending at 26,253.34 as investors rotated out of growth names amid rising borrowing costs; volume totaled 5.821 billion shares.

The downturn came as U.S. Treasury yields extended their recent climb, pressuring equities across the board. Higher yields tend to reduce the present value of future earnings, making technology and other high-valuation stocks particularly vulnerable. The moves also reflected growing anxiety over the Federal Reserve's next policy steps, with traders pricing in the possibility of further rate hikes if inflation proves stubborn.

Adding to the risk-off sentiment, oil prices surged sharply during the session as geopolitical tensions escalated in the Gulf region. Reports of continued hostilities disrupted supply routes and fueled fears of broader energy-market instability, sending crude benchmarks higher and compounding worries about sticky inflation.

Investors now look ahead to upcoming economic data, including weekly jobless claims and producer price figures, for further clues on the health of the economy and the trajectory of monetary policy. Meanwhile, geopolitical developments in the Gulf remain firmly in focus, with any escalation likely to keep oil prices elevated and add to market volatility in the sessions ahead.

U.S. Dollar Ends Wednesday Mixed as Yen, Euro, and Pound Advance; Loonie and Franc Lose Ground

The U.S. dollar traded Wednesday's trading session with a mixed performance against major currencies, losing ground against the Japanese yen, the euro, and the British pound, while posting gains against the Canadian dollar and the Swiss franc. The Australian dollar finished the day flat.

The greenback weakened against the yen, with the USD-JPY pair falling to 153.61, a decline of 0.24 percent, as traders continued to caution against further Bank of Japan intervention. Against the euro, the dollar also slid, with the EUR-USD pair rising to 1.1631, marking a gain for the common currency of 0.06 percent.

Sterling extended its recent strength against the dollar, as the GBP-USD pair climbed to 1.3546, an appreciation of 0.04 percent for the pound. The move came as markets digested fresh U.K. economic data and speculation over the Bank of England's next interest-rate decision.

Meanwhile, the U.S. dollar found firmer footing against its North American counterpart, with the USD-CAD pair advancing to 1.3807, a gain of 0.17 percent for the greenback. The loonie came under pressure amid softer crude oil prices and broader risk-off sentiment.

The dollar also strengthened against the Swiss franc, with the USD-CHF pair rising 0.11 percent to settle at 0.8103, as the franc gave back some of its recent safe-haven gains.

In contrast, the Australian dollar ended the session virtually unchanged, with the AUD-USD pair holding steady at 0.7217,. The currency remained range-bound as traders awaited key domestic employment data due later in the week.
