Military action begins as ceasefire tensions rise, with Iran warning of retaliation and global oil markets reacting sharply.

The U.S. Navy began enforcing a blockade of Iranian ports and coastal areas in the Strait of Hormuz on Monday following an order from Donald Trump, marking a significant escalation after failed diplomatic negotiations.

U.S. military officials confirmed the blockade took effect at 10:00 a.m. ET, targeting vessels entering or departing Iranian-controlled ports while allowing transit between non-Iranian destinations through the strategic waterway. The operation follows a breakdown in negotiations between the United States and Iran over the weekend.

The decision came after JD Vance returned from talks in Islamabad without an agreement. “The bad news is that we have not reached an agreement, and I think that’s bad news for Iran, much more than it’s bad news for the United States of America,” Vance said. He added, “So we go back to the United States, having not come to an agreement, we’ve made very clear what our red lines are, what things we’re willing to accommodate them on, and what things we’re not willing to accommodate them on.”

In a statement posted to his Truth Social account, Trump said the blockade was intended to counter what he described as “WORLD EXTORTION” by Iran, amid reports that Tehran was planning to impose fees on vessels transiting the chokepoint.

The Strait of Hormuz remains one of the world’s most critical energy corridors, handling an estimated 20% of global oil shipments. Tensions escalated after Iran previously restricted access to the waterway during the conflict, contributing to rising fuel prices.

Iranian officials rejected the U.S. action, with the country’s Revolutionary Guard warning that the strait would remain under its control and that any foreign military presence could prompt a “forceful response.” Tehran has described the blockade as “piracy” and signaled that it could bring an end to the existing ceasefire.

U.S. Central Command stated that the blockade would be enforced against all vessels attempting to access Iranian ports without authorization. “Any vessel entering or departing the blockaded area without authorization is subject to interception, diversion, and capture,” officials said in a notice to maritime operators.

Military activity in the region intensified ahead of the blockade, with U.S. forces reporting the movement of naval assets through the strait and conducting mine-clearing operations. Iranian officials disputed those claims.

Energy markets reacted immediately to the developments. Oil prices rose above $100 per barrel, reflecting concerns over potential supply disruptions. Analysts warned that physical crude supplies already in transit could be depleted within days, increasing pressure on global energy markets.

The collapse of negotiations underscored broader disagreements between the two sides. Iranian officials reportedly sought control over the strait, war reparations, access to frozen assets, and a reduction of U.S. military presence in the region, while U.S. negotiators insisted on commitments related to Iran’s nuclear program.

Regional allies also responded to the escalation. Benjamin Netanyahu expressed support for the U.S. position, stating that Israel backed the blockade following what he described as Iran’s failure to uphold ceasefire terms.

Additional diplomatic fallout emerged as Iranian President Masoud Pezeshkian publicly criticized Trump’s remarks about Pope Leo XIV, calling them unacceptable and defending the pontiff in a public statement.

Financial markets showed limited declines following the announcement, with major U.S. indices closing slightly lower after a week of gains tied to earlier ceasefire optimism. Analysts noted continued volatility as geopolitical uncertainty persists.

The blockade marks a significant shift in U.S. military posture in the region, with implications for global energy flows, diplomatic relations, and the stability of the ongoing ceasefire.
