The conflict between the U.S. and Iran, now over four months old, shows no signs of ending, despite a month-old "memorandum of understanding" (MOU) that secured a temporary ceasefire. This agreement, initially seen as a diplomatic achievement by both sides, has now crumbled, with military attacks and a renewed U.S. naval blockade on Iranian shipping. Rosemany Kelanid, Director of the Middle East program at Defense Priorities, stated, "The MOU is completely dead." This has left both nations in a familiar predicament, with Iran unable to export oil and facing renewed American military attacks, and the U.S. and its allies grappling with rising energy prices and continued attacks in the region.
President Trump's recent actions have further complicated the situation. On Monday, he announced a 20% fee on all vessels transiting the Strait of Hormuz, including those of U.S. allies, to reimburse the U.S. for security costs. This announcement caused oil prices to jump nearly 10%, the biggest one-day increase in six years. However, Trump abandoned this proposal the following day, opting instead for "trade and investment deals" with Gulf allies, implying safe passage through the Strait in return. This reversal, after calls from "kings and emirs," suggests a president struggling for a clear path forward, caught between the unpopularity of escalating war and the undesirable prospect of settling for an agreement not perceived as superior to the 2015 Iran nuclear deal.
The reimposition of the blockade by the U.S. followed Iran's attacks on commercial ships in the Strait of Hormuz, marking a definitive end to the interim ceasefire. This has led to concerns about a return to all-out war, particularly given that the strait is a vital shipping lane for a fifth of all traded crude oil and natural gas. The U.S. previously lifted a blockade in mid-June after the signing of the interim deal. The current price for Brent crude oil briefly topped $87 before dipping to $78 after Trump's decision to forgo tolls, still below the $120 reached at the war's peak. The collapse of the MOU has effectively ended the prospect of a negotiated settlement, pushing the conflict back to a "war of attrition," according to Kelanid, with no clear resolution in sight.
