Strait of Hormuz: A New Fault Line Between the US and Iran
The US and Iran are at an impasse over control of the Strait of Hormuz, with a vague memorandum of understanding raising the risk of new clashes.
The Strait of Hormuz, a crucial artery for oil and gas shipments, has once again become a flashpoint between Iran and the United States. The two sides interpret a hastily drafted memorandum of understanding (MoU) from June differently. Iran sees point five as a green light to manage the strait, while the US insists Tehran must ensure free passage.
Iran's new leadership, which emerged from weeks of war and US-Israeli assassinations, appears united on strategic vision but shows signs of internal splits on tactics. Some want to capitalize on battlefield gains through diplomacy, while others believe the ceasefire came too soon.
Recent Iranian attacks on three vessels, including a Qatari-flagged LNG tanker, have been described by a diplomatic source as the work of a "rogue unit" within the Islamic Revolutionary Guard Corps (IRGC). Iran insists vessels must use its designated routes, and parliament has introduced a new bill to manage the strait, called the Strategic Action for the Security and Sustainable Progress of the Strait of Hormuz and the Persian Gulf.
Iran views control of the strait not only as a bargaining chip but also as a new deterrent and economic lifeline if sanctions remain. However, Tehran's push to rewrite regional rules is causing tension with neighbors including Qatar and Oman. The UAE finds Iran's plan to charge "service fees" unacceptable.
Oman, a longtime neutral mediator, has objected to a specific mention in the MoU that Iran would hold dialogue with Oman on future administration. Omani analyst Abdullah Baabood said this episode has prompted Oman to take a substantial stand, but it still wants dialogue.
Both sides believe they emerged from the war with the upper hand and that the other will back down due to weaknesses. Iran faces deep economic crisis: inflation around 80%, millions of job losses, and suppression of protests. President Trump also faces political and economic pressures.
The MoU's unrealistic 60-day window for negotiations is another weakness. Former US official Robert Malley said the truce has a fair chance of recovering, but given dysfunctions on both sides, he wouldn't entirely wager on it.
