The S&P 500 fell 0.56% and the Dow Jones Industrial Average shed 538 points after President Trump’s latest comments on Iran, escalating geopolitical tensions already weighing on markets.
"Iran would be 'blown off the face of the Earth' if it were to attack U.S. ships," Trump said, according to a Fox News report.
The selloff was immediate, with the S&P 500's decline widening to 0.56% and the Dow falling 1.09%. The Nasdaq Composite dropped 0.44%, while banking stocks were hit particularly hard, with the KBW Bank Index falling over 1.9%. In commodities, New York gold futures saw a brief flight to safety before falling $5.79 per ounce.
The sharp rhetoric injects fresh uncertainty into a standoff that began after the killing of Iran's Supreme Leader in February 2026, which led to an Iranian blockade of the Strait of Hormuz. Prediction markets show waning confidence in a resolution, with the probability of Trump lifting a counter-blockade by May 31 falling to 31.5% from 56% last week, according to data from prediction market Kalshi.
The president's warning comes at a time of heightened military activity in the Persian Gulf. The U.S. is currently running "Project Freedom" to escort commercial vessels trapped by an American counter-blockade of Iranian ports. Recent unverified reports of machine gun fire near the Strait of Hormuz, a chokepoint for about a fifth of the world's oil supply, have suggested a potential shift from harassment to direct naval engagement.
This ongoing crisis has kept energy markets on edge. While WTI crude oil prices have been trending higher on the increased geopolitical risk, the direct impact of Trump's statement was most visible in equities as investors priced in a higher chance of a conflict that could disrupt the global economy.
The U.S.-Iran conflict is being complicated by the involvement of other global powers. China recently issued a blocking order to prevent its companies from complying with U.S. sanctions on Iranian petrochemical firms, a direct challenge to America's "Economic Fury" campaign. This has reduced the probability of a renewed US-Iran nuclear deal to just 15.5%, according to prediction markets.
Separately, U.S. Joint Chiefs Chairman General Dan Caine has confirmed that Russia is providing intelligence and weaponry to Iran as part of a strategic partnership. The deepening Russia-Iran alliance, coupled with China's economic defiance, creates a complex geopolitical backdrop that amplifies the risk of miscalculation and further escalation, a factor reflected in the market's bearish reaction.
