CENTCOM ended its 66-day naval blockade of Iran on 18 June, a day early. The strait stayed shut: foreign-flag ships absent, war-risk cover gone, mines uncleared for weeks. Sanctions relief, weapons checks and reconstruction all stayed on paper. Trump opened the one lock that was free to open, and signed deferrals for everything that costs.
Trump lifted the only lock the United States held free; the strait and the deal's substance remain shut.
US Central Command halted its naval blockade of Iran's ports on 18 June, a day ahead of its own wind-down, after 66 days of enforcement.
US Central Command halted naval blockade enforcement of Iran's ports on 18 June, one day early. The blockade ran 66 days, from 13 April to 18 June. Two carrier strike groups remained on station with no drawdown order.
The early end cost Washington nothing: mines and London insurers already held Hormuz shut. CENTCOM ending enforcement looked like MoU compliance while every lever of pressure stayed in place.
BIMCO's chief safety officer Jakob Larsen called Hormuz transits "still very risky" on 18 June as foreign-flag traffic stayed away and war-risk cover withheld.
United Statesthe strait of Hormuz stayed commercially shut on 18 June despite the blockade lift. Traffic ran at 5-10% of pre-conflict levels. London war-risk insurance had not returned, mines needed 40-50 days to sweep at minimum, and BIMCO's Jakob Larsen said transit was still very risky.
Mines and insurers hold the strait shut regardless of any diplomatic announcement. Nothing in the MOU unlocks either constraint.
Mojtaba Khamenei endorsed the US-Iran MOU in his first written message on 18 June, then branded the enemy's demands excessive and handed the deal's outcome to President Pezeshkian.
RussiaIran's Supreme Leader Mojtaba Khamenei issued a written statement on 18 June endorsing the MOU. He used the Farsi word doshman (enemy) to describe the US, said talks did not mean accepting the enemy's views, and delegated all accountability for outcomes to President Pezeshkian.
Khamenei built his exit before Phase 2 began. If negotiations collapse, the political cost falls on Pezeshkian, not on The Supreme Leader.
The US Treasury's sanctions office issued no Iran waiver, licence or delisting through 18 June; the MOU text ties full relief to a final agreement nobody has written.
United StatesOFAC, the US Treasury sanctions bureau, issued no Iran waiver, general licence, or delisting through 18 June. Its only updates that day covered Cuba and counter-terrorism. Marco Rubio told Congress on 2 June the US had not offered Iran sanctions relief.
the MOU text explains the gap: full sanctions relief is tied to a future final deal, not the interim framework. Only oil-transaction waivers apply immediately. The $100 billion in frozen assets stays locked.
The MOU commits Iran to destroy its enriched uranium stockpile under IAEA supervision; in the same 18 June message Khamenei called full inspector access an excessive demand.
United StatesRussiathe MOU commits Iran to destroying its 440.9 kg of 60% enriched uranium under IAEA supervision by a mechanism still to be agreed. IAEA Director General Rafael Grossi confirmed inspectors had been locked out for 97 days and could only assess the stockpile's location via satellite.
On the same day, Khamenei labelled full IAEA access and stockpile transfer 'excessive demands.' The document requires what the Supreme Leader just refused. Phase 2 opens with that contradiction on the record.
A Hezbollah attack killed four Israeli soldiers on 19 June, the deadliest on the Lebanon front since the MOU was signed; National Security Minister Itamar Ben-Gvir answered "all of Lebanon must burn", defying his own government's deal.
Israel×2United KingdomIran's foreign ministry spokesman Esmail Baghaei threatened MoU annulment on 18 June if Israeli forces stayed in south Lebanon. On 19 June a Hezbollah attack killed four Israeli soldiers near the Litani, and Israeli National Security Minister Itamar Ben-Gvir publicly demanded 'all of Lebanon must burn.'
A sitting cabinet minister defying the MOU his own government signed is a qualitatively new stress. Israel and Iran are now pulling the Lebanon clause in opposite directions simultaneously.
Brent crude held near $79.95 on 19 June, down about a tenth on the week, as traders priced a Hormuz reopening that no physical cargo has yet made real.
United StatesBrent Crude settled near $78.66 on 18 June, down roughly 10% on the week, as markets priced CENTCOM's blockade lift. By 19 June it edged to $79.95. The pre-conflict baseline was around $70, and no additional Gulf cargo had physically moved.
The UAE state oil company assessed stranded Hormuz barrels might not clear until 2027. Oil prices moved on the announcement; oil has not.
The remains of chief engineer Patnala Suresh reached Visakhapatnam on 19 June, completing the repatriation of three Indian crew killed by US fire, as Delhi summoned Washington's envoy twice without an apology.
United StatesThe remains of Patnala Suresh, 44, chief engineer of the MT Settebello, reached Visakhapatnam on 19 June, completing repatriation of all three Indian sailors killed when US forces struck the tanker on 10 June. India's Ministry of External Affairs summoned US Chargé d'Affaires Jason Meeks twice in a week.
Washington issued no apology, no investigation, and no signed instrument. Modi raised the deaths with Trump at the G7 on 17 June and received the same silence.
The USS Abraham Lincoln and USS George H.W. Bush held station in the Gulf on 18 June with no drawdown order, as the blockade they backed came down.
The USS Abraham Lincoln and USS George H.W. Bush held station in The Gulf on 18 June with no CENTCOM drawdown order issued alongside the blockade wind-down.
Washington ended enforcement while keeping the military infrastructure to reimpose it intact. Two carriers on station are the most visible signal that US coercive leverage over Iran remains fully in place through Phase 2.
Sideways. The MOU's 60-day window holds neither side free to escalate without formally repudiating a signed text, creating a holding pattern rather than a resolution. The mechanism that tips it upward: Baghaei's annulment clause activates if the IDF stays in south Lebanon and Hezbollah resumes fire; Iran's foreign ministry named that trigger explicitly on 18 June, and Israel killed 86 people in Lebanon on 18-19 June without withdrawing. The mechanism that tips it toward resolution: OFAC issuing a general licence or delisting, the first instrument-level proof that Washington is moving on sanctions, but Rubio's 2 June 2026 Senate testimony and the MOU's 'final agreement' conditionality make that unlikely before Phase 2 nuclear talks produce a text.
