Hezbollah killed an IDF reservist near the Litani on 18 June, the first death since the Iran memorandum was signed, and Tehran called continued Israeli presence grounds for annulment. The published text promised waivers and a lifted blockade immediately; the Treasury record is blank and two US carrier groups remain on station. Brent fell to $77 pricing a reopening that has not happened.
The MOU is signed; its three immediate clauses are each unimplemented on Day Three.
Master Sgt. Alexander Filin, 29, was killed near the Litani River at about 5pm on 18 June when a Hezbollah roadside bomb struck his unit in south Lebanon, the first combat death since the Iran memorandum was signed.
Israel×2A Hezbollah bomb killed Israeli reservist Master Sgt. Alexander Filin, 29, near the Litani River in south Lebanon on 18 June, wounding seven including a divisional deputy commander. It was the first IDF combat death since the Islamabad MOU was signed three days earlier.
The attack directly tests Article 1, which requires a ceasefire on all fronts including Lebanon. Israel never signed the MOU and its troops remain deployed. Iran's foreign ministry threatened MoU annulment within hours.
Iran's foreign ministry spokesman Esmail Baghaei told Lebanon's Al Akhbar on 18 June that continued Israeli presence in south Lebanon would mean annulment of the Islamabad memorandum, the first time Tehran has reached for that word.
QatarIsraelIranian foreign ministry spokesman Esmail Baghaei said on 18 June that Israel's continued presence in south Lebanon would mean 'annulment' of the Islamabad MOU. Annulment voids the entire agreement; it does not just invoke a dispute clause.
MoU Article 1 requires a ceasefire on all fronts including Lebanon. Israel never signed and its troops remain deployed. Tehran signed an agreement whose most visible provision depends on Israeli compliance it cannot enforce.
The 14-point Islamabad memorandum was released on 17 June with a clause requiring crude-export waivers immediately upon signing; three days on, the OFAC record carries no Iran waiver and the White House register shows nothing.
IsraelMoU Provision 3 required the US Treasury to issue crude oil export waivers to Iran immediately upon signing. Three days on, the OFAC public record carries no Iran waiver; The White House Presidential Actions register shows no Iran-related instrument on 17 or 18 June.
Brent fell 6.9% to $77.22 pricing that relief. If the waiver does not appear by 19 June, traders will start to reverse that move.
The USS Abraham Lincoln and the USS George H.W. Bush remained on station in the Gulf as of 18 June, the blockade still redirecting vessels, despite the memorandum's clause that it be removed immediately.
QatarUnited StatesThe USS Abraham Lincoln and USS George H.W. Bush remained on station in The Gulf on 18 June despite the Islamabad MOU's clause requiring the blockade's immediate removal. CENTCOM issued no drawdown order.
A signed diplomatic agreement does not constitute a military operational order; CENTCOM needs a written directive from the Defence Department chain. Live mines in the strait add a second barrier that no commercial vessel will cross without clearance.
The published memorandum bans tolls on Hormuz passage, then invokes UNCLOS Article 26(2) to recast the IRGC's toll body as an Iran-Oman provider of maritime services, with a charge-free window of only 60 days.
QatarIsraelThe Islamabad MOU bans Hormuz tolls for 60 days, then creates a joint Iran-Oman body to collect renamed 'maritime navigation services' fees under UNCLOS Article 26(2). Foreign Minister Araghchi confirmed on 17 June that charges will resume, and the IRGC-run Persian Gulf Strait Authority kept operating on 18 June under the new label.
Whether UNCLOS Article 26(2), written for port-approach charges, can cover a strait-wide passage fee is disputed. Iran has 60 days before the question could reach arbitration.
Brent crude fell to about $77.22 on 18 June, a pre-war level, while not one tanker resumed transit, insurers kept the strait excluded and the mines stayed live. The market is reading the signature; the water disagrees.
United StatesBrent Crude fell 6.9% to $77.22 on 18 June as markets priced the Islamabad MOU as a completed Hormuz reopening. No commercial tanker transited the strait: Iranian-laid mines remain uncleared, CENTCOM kept the blockade running, and no P&I club lifted its war-risk exclusion.
In past Gulf resolutions, paper pricing took six to fourteen days to meet physical reality. If no vessel transits by 25 June, Brent could rebound toward $82.
IRGC commander Ahmad Vahidi demanded that any released frozen assets fund military spending, including missile and drone rebuilding. The Institute for the Study of War put 60 days of oil exports at up to $10 billion; Senate opposition hardened.
United StatesIsraelIRGC commander Ahmad Vahidi demanded on 17 June that released Iranian frozen assets fund military spending. The Institute for the Study of War estimated 60 days of oil exports under the MOU could generate up to $10 billion for Iran's missile and drone programmes.
Senate Majority Leader John Thune said the same day he had not seen the MOU text and wanted financial incentives conditioned on Iran ending its nuclear programme; Republican opposition to the $300 billion package hardened.
The remains of two of the three Indian sailors killed aboard the tanker MT Settebello were repatriated through Oman on 18 June. No US apology has followed, and no investigation has been opened.
The remains of two Indian sailors killed when US forces struck the tanker MT Settebello on 11 June were repatriated through Oman on 18 June. The three dead, Aditya Sharma, Shivanand Chaurasiya and Patnala Suresh, were the first non-belligerent nationals killed by US fire in the conflict.
Prime Minister Modi raised the deaths with Trump at the G7 the day before. No US apology or investigation has followed, and India's Quad partnership limits how hard Delhi can push.
Direction: upward on the Lebanon track; sideways on Hormuz. The Lebanon track tips if Khamenei endorses Baghaei's annulment language before 19 June, converting the civilian foreign ministry's threat into a supreme-leader-level commitment and collapsing the Geneva ceremony; Khamenei has communicated only by handwritten courier since 8 March 2026 with a three-to-five-day lag, making his position unknown as of 18 June. On Hormuz, the likeliest escalation trigger is a second IRGC radio challenge to a US vessel during mine-clearance operations, as happened on 15 June; an accidental exchange of fire voids the MOU's military track before the 60-day nuclear window opens. The Senate track moves within the week: if Thune tables conditioning language tied to Vahidi's missile-spending demand, the $300 billion reconstruction package acquires a legislative blocker before Iran sees a dollar of relief.
