U.S. stock futures tumbled Sunday night, and oil prices jumped amid escalating tensions with Iran after President Donald Trump said that an Iranian-flagged cargo ship had been seized in the Strait of Hormuz.
Dow Jones futures slid by more than 0.7% around 9.40 PM ET, the S&P 500 futures slid 0.5%, while the Nasdaq 100 futures declined 0.5%.
The SPDR S&P 500 ETF (SPY) fell about 0.69% in overnight trading, Invesco QQQ Trust (QQQ) edged 0.46% lower, and SPDR Dow Jones Industrial Average ETF Trust (DIA) declined 0.67%. Meanwhile, on Stocktwits, retail sentiment around the S&P 500 ETF was in the ‘extremely bullish’ territory at the time of writing, amid ‘low’ message volumes.
After a week of optimism around de-escalations that drove markets to record highs and lowered oil prices, Trump said on Sunday that the U.S. Navy had fired on the Iranian ship that had allegedly attempted to pass the blockade despite warnings, as a ceasefire between the two countries is set to expire this week.
“The U.S. Navy Guided Missile Destroyer USS SPRUANCE intercepted the TOUSKA in the Gulf of Oman, and gave them fair warning to stop. The Iranian crew refused to listen, so our Navy ship stopped them right in their tracks by blowing a hole in the engineroom. Right now, U.S. Marines have custody of the vessel,” Trump said in a post on Truth Social.
In an earlier post, the president also threatened to hit Iran’s power plants and bridges if they failed to take a deal. “We’re offering a very fair and reasonable DEAL, and I hope they take it because, if they don’t, the United States is going to knock out every single Power Plant, and every single Bridge, in Iran,” he said, adding that U.S. representatives would be visiting Pakistan on Monday evening to negotiate further.
Over the weekend, Iran reversed an earlier decision to reopen the critical sea route after Trump announced that the U.S. Navy blockade of Iranian ports would stay, sending oil prices soaring back up.
