4 min read
12:41UTC

Twenty-six governments including Bahrain and Qatar signed a UK-French Hormuz coalition paper on 12 May; Iran's Foreign Minister Abbas Araghchi codified the opposite doctrine via Mehr News, saying the strait stays open to friendly nations and closed to adversaries. Brent crude reached $109.30 on 16 May. The White House has signed no Iran instrument in 78 days.

Key takeaway

Two Hormuz governance papers are now on the table; Washington signed neither.

The UK and France co-convened 38 governments and 26 signed the Multinational Military Mission for the Strait of Hormuz on 12 May, putting Bahrain and Qatar on Western coalition paper for the first time since the war began.

Twenty-six governments signed a joint statement on 12 May formalising the Multinational Military Mission for the Strait of Hormuz, with Bahrain and Qatar appearing on Western Hormuz Coalition paper for the first time since Operation EPIC FURY began. The UK and France co-convened 38 nations; the statement was published on GOV.UK on 14 May. The mission mandate covers freedom of navigation, civilian shipping support, and mine clearance. Operations will begin only 'in a permissive environment'. No rules of engagement were published, no commander named, and no deployment date set.

The signed coalition is the first multilateral instrument with Gulf-state buy-in, but the United States did not sign and the mission only activates 'in a permissive environment' that does not yet exist.

Briefing analysis

The standing precedent for a Gulf maritime coalition is Combined Maritime Forces (CMF), stood up in 2002 with CTF-152 specifically tasked to the Persian Gulf. Through every Gulf maritime episode since, including the 1980s tanker war's reflagging operation, the post-2003 Iraq insurgency interdiction work, and the 2019 IMSC (International Maritime Security Construct) after the Stena Impero seizure, the United States has held the drafting pen and the operational headquarters.

The 26-nation text signed on 12 May 2026 inverts that template. The drafting work is at Northwood (the UK Permanent Joint Headquarters), the legal spine is European (UNCLOS transit-passage doctrine, P&I (protection and indemnity) club templates), and the Gulf signatories sit alongside European partners rather than under American command. CENTCOM's role in this document is to be 'briefed on the outcome'.

First credible multilateral text in maritime law holds longer than any party's preference to revise it. Whatever this coalition produces between now and the 100-day mark on 8 June will frame any future US Hormuz arrangement, which will have to either reach into the European framework or argue around it.

Iraq cleared a 2-million-barrel VLCC and Pakistan secured passage for two Qatari LNG vessels through Iran in mid-May; Foreign Minister Abbas Araghchi told Mehr News the Strait is 'open to friendly nations, restrictions apply only to adversaries'.

Iran ran the strait of Hormuz as a bilateral state-to-state passage system in mid-May, codified publicly by Foreign Minister Abbas Araghchi and documented operationally by OilPrice.com with Windward vessel-tracking corroboration. Araghchi told Mehr News on his return from the BRICS foreign ministers meeting in New Delhi: 'the strait of Hormuz is open to friendly nations, and restrictions apply only to adversaries.' OilPrice reported the operational implementation: Iraq negotiated transit for a Very Large Crude Carrier of approximately 2 million barrels and was in talks for additional tankers, while Pakistan secured passage for two Qatari LNG vessels through a bilateral Pakistan-Iran agreement. Neither Iraq nor Pakistan paid the Persian Gulf Strait Authority yuan tolls directly; Tehran accepted political engagement in lieu of yuan. The physical Iranian crude premium collapsed from over $30 per barrel above Brent in early April to near-parity by mid-May.

Tehran has codified a parallel passage doctrine alongside the Persian Gulf Strait Authority toll system, converting Hormuz access from a yuan-priced fee into a declared political alignment with Iran

Brent crude closed Saturday 16 May at $109.30, $3.30 above the post-summit settle of $106.00 and $36.30 above Day 1 of the war; meanwhile the physical premium on Iranian crude collapsed to near-parity as the dark fleet absorbed the blockade.

Brent Crude reached $109.30 on Saturday 16 May, up $3.30 from the post-summit close of $106.00 on 14 May and above the $107.77 ceiling registered on 12 May. The benchmark reversed the dip that followed the Trump-Xi summit's verbal output, pricing back in the absence of any signed US Iran instrument. In parallel, the physical premium on Iranian-routed crude collapsed to near-parity with Brent by mid-May, from over $30 per barrel above Brent in early April. The benchmark prices geopolitical risk while the physical market reflects dark-fleet supply absorption of the blockade.

Two oil markets are telling opposite stories: the benchmark is repricing the absence of any signed US Iran instrument while the physical market shows the embargo has structurally failed at the cargo level.

Admiral Brad Cooper, CENTCOM commander, told a Washington defence forum on Thursday 14 May that US operations had cleared 'roughly 90 per cent' of Iran's naval mine inventory and that Iran's military threat is 'diminished but not eliminated'.

Admiral Brad Cooper, CENTCOM Commander, told a Washington defence forum on 14 May that US operations had cleared 'roughly 90 per cent' of Iran's naval mine inventory and that Iran's military threat is 'diminished but not eliminated', as reported by Defense News. The figure arrived with no published methodology and no independent corroboration. Cooper's previous '100 per cent halt' claim had been contradicted by Windward, The National, and LSEG. The Larak-Qeshm corridor between Iranian islands is the central Strait shipping lane Iran declared a mine zone.

Cooper's previous '100 per cent halt' claim was contradicted by three independent maritime-surveillance platforms; a second challenged figure would erode the operational credibility underwriting Pete Hegseth's Article 2 doctrine.

Hengaw documented the execution of Reza Soleimani at Qom Central Prison on Friday 15 May and an unnamed prisoner at Karaj Central Prison the same day, extending the multi-day judicial cluster that began on 11 May.

Hengaw, the Norway-based Kurdish human rights organisation, reported that Reza Soleimani was executed at Qom Central Prison on 15 May and an unnamed prisoner was executed at Karaj Central Prison on the same day. Karaj Central is the same facility where aerospace researcher Erfan Shakourzadeh was secretly executed on 11 May. The Friday executions extended the cluster Hengaw documented across 12-13 May and formed part of a five-prison execution footprint spanning Qezel Hesar Karaj, Mashhad, Karaj Central, Qom Central, and Gorgan.

Hengaw remains the only independent source documenting war-era judicial executions inside Iran; the 15 May killings raise the verified Hengaw count to nine since 11 May across a five-prison footprint. 

On Saturday 16 May, Kurdish singer Seyed Ali Qoreishi vanished incommunicado in Bukan, Shahram Pasupish was taken in Piranshahr, Hadi Abbasian was transferred to a Shirvan prison and Mohammadreza Faryadi was held incommunicado in Ilam.

On 16 May Hengaw recorded four Kurdish arrests across northwestern provinces: Kurdish singer Seyed Ali Qoreishi remained incommunicado in Bukan; Shahram Pasupish was arrested in Piranshahr with unknown whereabouts; Hadi Abbasian was transferred to prison in Shirvan; Mohammadreza Faryadi was held incommunicado in Ilam Province. English teacher Forouzan Eslami was arrested in Urmia on 15 May. The arrests are concentrated in Kurdish-majority provinces Hengaw monitors most closely.

The arrests run on the wartime security pipeline's own timetable rather than the kinetic war's; with the internet blackout nearing 2,000 hours, Hengaw's named-individual reports are the only granular record reaching the outside world. 

Israel's Elbit Systems received a $34 million contract to extend the operational range of F-35I Adir fighter aircraft, citing the active conflict with Iran, as reported by Defense News on Thursday 14 May.

Israel's Elbit Systems received a $34 million contract to extend the operational range of F-35I Adir fighter aircraft, citing the active conflict with Iran, as reported by Defense News on 14 May. The contract represents a medium-term Israeli force posture adjustment for longer-range strike options.

The procurement signals Israeli preparation for longer-range strike options against Iran's eastern nuclear facilities, even as Israel remains outside the direct US-Iran belligerent track.

Iran International reported on Friday 15 May that the Iranian Majlis was reviewing a bill proposing a €50 million reward for killing US President Donald Trump, framed as retaliation for the deaths of Iranian leaders.

Iran International reported that the Iranian Majlis was reviewing a bill proposing a €50 million reward for killing US President Donald Trump, framed as retaliation for the deaths of Iranian leaders. The bill was not corroborated by IRNA, Tasnim, or Mehr News as of 16 May. The briefing treats it as opposition-source narrative intelligence on hardliner domestic pressure rather than confirmed legislative action.

If confirmed, this would be the first time Iran's parliament formally proposed a bounty on a sitting US president, and would functionally destroy Foreign Minister Araghchi's civilian diplomatic track overnight. 

Closing comments

Sideways with institutional calcification. Cooper's blockade count stood at 61 vessel redirections by 10 May; his 90 per cent mine-clearance claim on 14 May lacks independent corroboration from Windward, Kpler, or LSEG, the three platforms that contradicted his earlier '100 per cent halt' assertion on 15 April. The Majlis Hormuz sovereignty law of 2 May and the PGSA toll system, confirmed at $2 million per vessel by Lloyd's List on 7 May, represent Iranian institutional advances that will outlast any kinetic pause. The signal for upward movement is Iran granting bilateral passage to Turkey or India, which would demonstrate defection from the Western coalition is geopolitically cost-free; the signal for downward movement is an independent maritime-surveillance dataset corroborating the 90 per cent mine figure, which would shift P&I insurers' calculus on war-risk cover for Hormuz.

Different Perspectives
Iranian government (Araghchi / Pezeshkian civilian track)
Iranian government (Araghchi / Pezeshkian civilian track)
Araghchi returned from the BRICS foreign ministers' meeting in New Delhi on 15 May and codified Iran's strait doctrine publicly: the Hormuz is open to friendly nations, closed to adversaries. The bilateral Iraq and Pakistan passage deals are the operational implementation of that doctrine, giving Tehran selective leverage without requiring a formal ceasefire.
United States (Trump administration / CENTCOM)
United States (Trump administration / CENTCOM)
Cooper's forum claim that 90 per cent of Iran's mine inventory has been cleared was the week's headline assertion from Washington; the White House posted zero Iran executive instruments through Day 78. The administration is prosecuting a military campaign under a Truth Social authorisation while declining to produce any signed legal architecture.
United Kingdom and France (coalition convenors)
United Kingdom and France (coalition convenors)
London and Paris co-convened 38 nations and secured 26 signatures on the Hormuz coalition paper, the first multilateral instrument to bring Gulf states onto Western coalition paper since the war began. The 'permissive environment' trigger binds the mission to a post-ceasefire window; no commander or rules of engagement have been published.
Bahrain and Qatar (Gulf signatories)
Bahrain and Qatar (Gulf signatories)
Both signed the Western coalition paper while hosting US Fifth Fleet and CENTCOM's Al Udeid base, respectively. Qatar occupies the sharpest contradiction: it is on coalition paper while simultaneously receiving LNG passage through the bilateral Iran-Pakistan track, a position Doha has tacitly accepted from both sides.
Iraq (bilateral passage partner)
Iraq (bilateral passage partner)
Baghdad negotiated a 2-million-barrel VLCC transit without paying PGSA yuan tolls, offering political alignment in lieu of cash. Iraq's position inside Iran's adjacent bloc makes it the natural first bilateral partner and a template for how Tehran structures passage deals with states that cannot afford Western coalition membership.
China and BRICS bloc
China and BRICS bloc
Beijing endorsed Pakistan's mediatory role on 13 May, one day after the BRICS foreign ministers' meeting in New Delhi. Chinese state banks are processing PGSA yuan toll payments; China has not commented on its vessels' continued Hormuz passage, but benefits structurally from a non-dollar toll system it did not design.
