With a proposed round of U.S.-Iran talks in Pakistan still up in the air, President Donald Trump on Tuesday extended a two-week ceasefire but kept a blockade of Iranian ports in place, prolonging a standoff that has largely shut the Strait of Hormuz and rattled energy markets
The extension averts an immediate deadline that had raised fears of renewed strikes, while leaving Washington’s economic and military pressure intact. Tehran has not confirmed whether it will attend talks that Pakistan is trying to host, and both sides have said they are prepared to resume fighting if diplomacy falters
What changed
Trump said he extended the truce at the request of Pakistan’s prime minister and directed the U.S. military to maintain the blockade while remaining on alert. Iran’s top negotiator, Mohammad Bagher Ghalibaf, dismissed the move as a ploy and warned that continuing the port blockade would be met militarily
U.S. Vice President JD Vance is expected to lead American negotiators if the talks go ahead in Islamabad, but he remained in Washington on Tuesday, according to the White House. Pakistan, which has urged both sides back to the table, said it was awaiting Iran’s confirmation
Iranian Foreign Minister Abbas Araghchi called the port blockade an “act of war” and a violation of the ceasefire. Iranian officials have said they will not negotiate under threats and have hinted at new options if hostilities resume
Pressure at sea—and on markets
In parallel with the diplomacy, the Pentagon said U.S. forces on Tuesday boarded the M/T Tifani, an oil tanker previously sanctioned for moving Iranian crude, describing the operation as carried out without incident in the Indian Ocean. It followed the weekend seizure of an Iranian cargo vessel, the first interception under the port blockade. Iran’s military has labeled such boardings piracy and a breach of the truce
The core dispute centers on Iran’s restrictions in the Strait of Hormuz, a chokepoint for roughly 20% of the world’s crude oil and natural gas flows in peacetime. The United States is demanding that vessels be allowed to transit freely again; Tehran has tightened control since the war began in late February
The squeeze has pushed prices higher: Brent crude traded near $95 a barrel on Tuesday, up more than 30% since Feb. 28, when the United States and Israel launched strikes on Iran. European Union transport ministers met in Brussels to discuss consumer protections as the head of the International Energy Agency warned Europe may have roughly six weeks of jet fuel supplies remaining
The immediate question is whether Iranian negotiators show up in Islamabad and, if they do, whether the extension of the ceasefire and continued blockade create space or harden positions. Trump has alternated between touting military readiness and signaling openness to talks; Iranian negotiators say they will not bargain under coercion
Any movement at the strait—either toward reopening or toward escalation at sea—would quickly affect shipping costs, fuel prices and flight schedules. The stakes also extend beyond the bilateral track: separate, historic talks between Israel and Lebanon are expected to resume in Washington later this week under a 10-day ceasefire in Lebanon
Confirmation of Iran’s attendance and the makeup of delegations if talks convene in Islamabad
Further U.S. interdictions of ships under the blockade and any Iranian response at sea
Signals from energy markets and European authorities as jet fuel supplies tighten
Trump has said the ceasefire will remain in effect “until” Iran submits a proposal and discussions conclude. A breakdown at the talks—or an incident at sea—would be the clearest sign the picture has shifted
