(Bloomberg) — US equity-index futures dropped and oil climbed after US President Donald Trump’s warning that he may significantly escalate the war in Iran, potentially worsening an energy-price shock that’s already upending the global economic outlook.
Futures contracts for the S&P 500 Index retreated 0.4% as trading started Monday. Brent crude oil rose 1% to $110 a barrel.
Trump renewed threats early Sunday to attack Iranian infrastructure if the key energy-shipping route through the Strait of Hormuz remains closed. He followed it later with another that said: “Tuesday, 8:00 P.M. Eastern Time!” with no further explanation.
The president’s comments came as OPEC+ warned that damage to Mideast energy assets will have a prolonged impact on oil supply even after the conflict ends. Yet it’s showing little sign of progressing toward a ceasefire as attacks have continued to flare around the region, keeping key oil prices hovering well above $100 a barrel.
“The prediction game remains quite tricky for investors,” said Homin Lee, a strategist at Lombard Odier. “Investors’ focus will squarely be on military actions on both sides of the Persian Gulf and whether or not Hormuz vessel crossings can improve further despite these attacks.”
The fallout from the war has rapidly darkened the economic outlook by threatening to cool growth and push up already elevated inflation, roiling bets on whether the Federal Reserve will resume cutting interest rates later this year. Attention remains firmly on energy prices and the closure of the Strait of Hormuz — a waterway crucial for the flow of oil from the Middle East.
It’s going to be a key week for investors with the US inflation report due out on Friday. The roughly $1 per gallon increase in US gasoline pump prices probably drove the March consumer price index up 1%, the most since the post-pandemic inflation surge in 2022, according to an economist survey before the data is published.
The S&P 500 is coming off its best weekly gain of the year, a 3.4% jump fueled by short covering and speculation early in the week that Trump was poised to begin wrapping up US military operations. The gains left the index just 5.7% below its January record.
But on Thursday, the last trading day of the holiday-shortened week, US stocks initially opened lower after Trump’s televised evening address dashed optimism he would layout a solid timeline for concluding the war. Equities later recovered the losses on reports that Iran was talking with Oman about ways to handle shipping traffic through Hormuz.
