U.S. stock markets moved lower on Tuesday as investors reacted to stronger-than-expected inflation data and rising uncertainty surrounding the ongoing tensions between Washington and Tehran.
The benchmark S&P 500 fell nearly 1%, while the tech-heavy NASDAQ Composite posted steeper losses as technology shares came under pressure. The Dow Jones Industrial Average also traded lower during the session.
Despite the decline, major U.S. indexes remain close to record highs after months of strong gains driven by artificial intelligence optimism, resilient corporate earnings, and earlier hopes that tensions in the Middle East could ease.
However, investor sentiment shifted after the latest inflation report showed consumer prices rising faster than analysts had expected in April. According to fresh economic data, headline inflation climbed 0.6% on a monthly basis and 3.8% compared to a year ago, marking the highest annual inflation reading since mid-2023.
Core inflation, which excludes volatile food and energy prices, also came in above forecasts. Analysts noted that higher energy costs were a major driver behind the increase, as oil and gasoline prices continued to surge due to instability in the Middle East.
Energy prices recorded another strong monthly increase, while gasoline costs jumped sharply compared to the same period last year. Although the pace of monthly fuel price growth slowed from March’s spike, energy inflation remains a major concern for both consumers and policymakers.
Market analysts say the hotter inflation data could force the Federal Reserve to keep interest rates elevated for longer than investors previously expected. Traders increased their expectations for potential rate hikes later this year following the inflation release.
The report arrives during a significant leadership transition at the Fed, as current Chair Jerome Powell is nearing the end of his term. President Donald Trump is expected to appoint former Fed governor Kevin Warsh as the next central bank chief, a move investors are watching closely.
Meanwhile, geopolitical tensions between the United States and Iran continue to add uncertainty to global markets. Trump stated that ceasefire discussions with Tehran were barely alive after rejecting Iran’s latest proposal, describing it as unacceptable.
There are also increasing concerns that military tensions could escalate again if diplomatic efforts fail. Reports suggest that the White House is considering stronger military measures while negotiations remain stalled.
The uncertainty surrounding the conflict has pushed oil prices higher once again. Brent crude climbed above $108 per barrel, while U.S. crude prices moved above $101, keeping pressure on inflation and raising concerns about the broader global economy.
In company news, GameStop shares fell after eBay rejected a reported takeover proposal from the retailer. Meanwhile, Under Armour shares dropped sharply after disappointing earnings guidance, while Hims & Hers Health also declined following weaker-than-expected quarterly results.
Investors are expected to remain cautious in the coming weeks as inflation pressures, central bank uncertainty, and geopolitical risks continue to dominate global financial markets.
