U.S. demand for a public commitment on the strait

The Trump administration is demanding that Iran publicly commit to keeping the Strait of Hormuz open and secure for free transit . This demand came after Iranian forces fired on commercial vessels. U.S. officials have insisted that private assurances are insufficient and that a public pledge is necessary to proceed with the diplomatic track .

Iran's private admission that the attacks were a mistake

According to senior U.S. officials, Iranian officials privately told advisers to President Trump that they "made a mistake" by shooting at commercial ships in the Strait of Hormuz . Tehran reportedly attributed the attacks to an "errant" sect of hardliners who were acting without approval and trying to undermine the negotiations . Iran conveyed that it wants to continue talking despite the attacks .

U.S. revocation of Iran's oil export license and new sanctions

On July 7, 2026, the Treasury Department formally revoked General License X1 — the authorization that had permitted the sale of Iranian crude oil, petrochemical products, and petroleum products — after Iran attacked three commercial tankers in the strait . A U.S. official called the attacks "wholly unacceptable" .

Separately, in May 2026, the U.S. State Department sanctioned several Iranian currency exchange houses, associated personnel, front companies, and 19 vessels as part of the "Economic Fury" campaign targeting Iran's sanctions-evasion networks and the financing of destabilizing activities . OFAC records also show a General License Y authorizing wind-down of transactions involving Smart Global Limited, linked to Khamenei-related financing networks .

Diplomatic timeline under the June MoU (Pakistan-brokered)

On June 17–18, 2026, Trump and Iranian President Masoud Pezeshkian signed a memorandum of understanding to end the U.S.-Iran war, halt the U.S. blockade, and reopen the Strait of Hormuz . Pakistan's Prime Minister Shehbaz Sharif mediated the agreement, with Qatar also facilitating parallel talks . Under the MoU, substantive talks on Iran's nuclear program were deferred until after sanctions relief and the reopening of the strait .

Expiration deadline and broader stakes

The MoU faces severe strain. Both sides threatened on July 8 to scuttle the agreement after the tanker attacks and U.S. strikes . Traffic through the strait remains at roughly one-third to one-fifth of pre-war levels . The U.S. also revoked the oil waiver on July 7, reimposing maximum economic pressure. If the diplomacy collapses, analysts warn of a return to open conflict, as Iran sees its hold on the strait as its chief bargaining chip and the U.S. demands unimpeded global oil transit .
