Late Sunday, U.S. stock futures slid sharply while oil prices surged after escalating tensions between Washington and Tehran raised fears of a major global energy supply disruption.

Trump Escalates Pressure With Blockade Threat

Earlier on Sunday, Donald Trump said that the U.S. Navy would begin efforts to block ships entering or leaving the Strait of Hormuz.

“Effective immediately, the United States Navy… will begin the process of blockading any and all ships” transiting the strait, Trump said on Truth Social.

The U.S. Central Command later confirmed, saying it will begin blocking all maritime traffic to and from Iranian ports starting at 10 a.m. ET on Monday. It added that vessels traveling to or from non-Iranian ports will not be affected.

Failed Talks Add To Uncertainty

Diplomatic efforts to end the conflict collapsed after high-level talks in Pakistan failed to produce an agreement.

Vice President JD Vance said negotiations broke down over Iran’s unwillingness to commit to abandoning nuclear weapons development.

Iranian Foreign Minister Abbas Araghchi accused Washington of shifting demands at the last minute. “Good will begets good will. Enmity begets enmity,” he wrote on X.

It remains unclear whether Trump will resume airstrikes on Iran.

Strait Of Hormuz Disruption Raises Global Alarm

The Strait of Hormuz handles roughly one-fifth of global oil flows, making any disruption a major threat to energy markets.

Tanker traffic has already declined sharply amid security concerns.

Three supertankers completed the transit on Saturday, according to LSEG data, each capable of carrying up to two million barrels of oil, CNBC reported.

However, overall traffic remains far below prewar levels when more than 100 vessels passed through daily.
