U.S. stock futures fell Monday after President Donald Trump stated a blockade of the Strait of Hormuz, as peace talks between the U.S. and Iran over the weekend ended without a deal.

Dow Jones Industrial Average futures were down 255 points, or 0.5%. S&P 500 futures shed 0.6% along with Nasdaq-100 futures.

“Effective immediately, the United States Navy, the Finest in the International community, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz,” Trump wrote on Truth Social. “The Blockade will begin shortly. Other Countries will be involved with this Blockade. Iran will not be allowed to income off this Illegal Act of EXTORTION.”

The breakdown of negotiations over the weekend in Islamabad reignited worries that the U.S.-Iran war will last longer than feared, leading to higher oil prices that will continue to strain economies worldwide.

West Texas Intermediate crude oil jumped 8.1% to $104.38 a barrel. International Brent popped 7.8% to $102.64.

U.S. Central Command remarked it will begin blocking all maritime traffic in and out of Iran’s ports at 10 a.m. ET Monday. The U.S. commented it will not block vessels using the strait to get to non-Iranian ports.

Vice President JD Vance left Islamabad without a deal with his Iranian counterparts, citing their unwillingness to stop the pursuit of nuclear weapons. But both sides appear farther apart than just that issue with Iran demanding control of the Strait of Hormuz, war reparations and the release of frozen assets. Pakistan officials commented they would try to restart talks in the coming days.

Trump, who revealed the naval blockade after talks broke down, is weighing resuming military strikes, the Wall Street Journal reported, citing officials familiar with the situation.

“The latest blockade statement is an overt signal to equity markets that the Iranian conflict remains uncertain, yet traders are viewing this development as negotiation tactic versus an actual policy implementation, or as a long-term solution for the Strait of Hormuz,” stated Jeff Kilburg, CEO of KKM Financial.

Kilburg remarked it’s possible more buyers come in before the marketplace opens Monday. Furthermore, experts in investors note the continued relevance.

Hopes for a swift end to the war helped all three major benchmarks post their best week since November, following the announcement of a two-week ceasefire between the U.S. and Iran. The S&P 500 rallied 3.6% last week, while the Nasdaq jumped about 4.7%. The Dow gained 3%.

First-quarter earnings season unofficially kicks off this week. The nation’s largest banks will get it started, with Goldman Sachs slated to release results on Monday. Citigroup, Wells Fargo, JPMorgan Chase, Morgan Stanley and Bank of America are all on the docket later this week.

Trump weighs limited strikes on Iran, Wall Street Journal reports

U.S. President Donald Trump and his advisers are considering resuming limited military strikes in Iran, following a breakdown in negotiations with the country, citing officials and individuals familiar with the situation.

The president was reportedly weighing the option on Sunday. He could also ramp up his bombing campaign to full force, though officials mentioned that was less likely so as to avoid destabilizing the region further, the report commented. He could also pursue a temporary blockade as he pressures allies to take the lead in military escort through the strait.
