Oil traders were not handed a peace deal this week but a contract with three different enforcement mechanisms and one major party outside the room.
Iran’s reported move to again restrict the Strait of Hormuz after Israeli strikes in Lebanon has turned the new US-Iran framework into a test of leverage rather than diplomacy. The document may give Washington a path to sanctions relief, Tehran a path to economic re-entry, and markets a route toward lower energy risk. But the arrangement now depends on whether Israel-Hezbollah fighting can be contained fast enough to keep Iran from using the world’s most important oil chokepoint as pressure.
That is the flaw now sitting inside the 14-point memorandum of understanding.
According to source-specific reporting from the New York Post, Iran’s Islamic Revolutionary Guard Corps moved to close the strait again until Israel withdraws from southern Lebanon, naval restrictions are lifted, and US forces leave the Persian Gulf.
But the market problem exists even without treating the closure claim as fully settled. The strait had not returned to normal conditions.
The Guardian reported that around 80 naval mines were still blocking the main route through Hormuz, leaving commercial traffic dependent on narrower and riskier alternatives. The same reporting said hundreds of vessels remained stuck in the Gulf, while signal interference and proposed Iranian tolls added further complications for operators.
That means the deal did not restore a clean maritime corridor.
Reuters reported that some tanker movement had resumed, including vessels moving toward Iraqi ports, with Business Insider reporting that 25 vessels were verified crossing the strait on June 18.

The agreement set up a 60-day window for negotiations after a provisional halt in hostilities, aimed to buy time to finalize the deal. The 14-point framework covered Hormuz, sanctions relief, nuclear talks, and a proposed $300 billion fund for Iran. The plan offered both sides a way to step back from escalation while leaving the hardest issues for follow-up talks.
Those follow-up talks are already under pressure. Planned US-Iran talks in Switzerland were called off after Vice President JD Vance abandoned travel plans, delaying the next phase of negotiations.
The timing is damaging because the deal relies on sequencing: Iran wants evidence that Washington is acting on sanctions, oil access, and financial relief; the US wants evidence that Tehran will keep shipping lanes open and accept nuclear constraints; shipping companies want a route that insurers can price without assuming another closure; and Israel wants room to act against Hezbollah.
Lebanon has become the stress point because it sits outside the US-Iran text but inside Iran’s regional calculus. Reuters reported that Israel and Hezbollah agreed to a ceasefire starting at 4 p.m. local time on June 19 after a surge in violence. The same reporting said Israeli strikes killed at least 47 people in Lebanon, while a Hezbollah attack killed four Israeli soldiers. The ceasefire was brokered with US and Qatari involvement, though clashes continued around the implementation window.
Brent crude rose modestly Friday but was still on track for an 8% weekly decline as some supply began moving through the strait.
Washington may have negotiated a framework with Tehran but it did not negotiate Israeli military doctrine, Hezbollah’s battlefield choices, mine clearance schedules, tanker insurance rules, or Iran’s future transit demands through Hormuz.
That leaves the agreement vulnerable to enforcement arbitrage. Each side can claim compliance with its own part of the bargain while blaming another actor for the failure of the whole structure.
