Parties3 groups, and what each one means
- IranThe Iranian state and the forces under its command. One actor, not a bloc of allies — the module treats Iran's partner relationships as separately graded rather than as membership of a camp.
- Gulf Arab statesThe six members of the Gulf Cooperation Council. Grouped by institution, never by position: their responses to the current war differ materially, and each actor record states its own.
- External powersStates and institutions acting on this system from outside it — as belligerents, security guarantors, customers or regulators.

Where this conflict stands
Graded per item · As of 2026-09
Iran and the Arab Gulf states form one system, and its defining feature is concentration. The region's hydrocarbon exports, a large share of its electricity and nearly all of its drinking water depend on a small number of fixed installations reachable from a single narrow waterway. Security competition here is therefore not mainly about territory. It is about access — who can move what, through where, and at what price. This module explains the systems that carry Gulf oil and gas, the states that depend on them, and what is structurally exposed when they are disrupted.

Coverageby country
- Iran35 recordsOne pole of the system, and the actor whose decisions determine access to the strait. The deepest lens in the module: the state and its government layer, the three parallel armed structures and the general staff above them, the nuclear verification file, Kharg Island and the Goreh–Jask line, and the relationships that carry the war and the sanctions architecture.
- Saudi Arabia37 recordsThe largest producer and the owner of the principal Hormuz alternative. The lens holds the state and its government layer, the armed forces and the separately commanded National Guard, the East–West pipeline and its Red Sea outlet, Ras Tanura and Abqaiq, and the defence arrangements reached outside the Cooperation Council.
- United Arab Emirates18 recordsThe most heavily struck Gulf state and owner of the second bypass. The lens holds the state and its government layer, the armed forces, the ADCOP corridor to Fujairah with the Habshan and Ruwais complexes, and the security relationship with Israel.
- Qatar13 recordsThe most structurally exposed state in the system, and its principal mediator. The lens holds the state and its government layer, the armed forces, Ras Laffan and the North Dome field it draws on, the liquefaction capacity lost in March 2026, and the mediation channel it has kept open through the war.
- Kuwait12 recordsWhere the region's power-and-water dependence is sharpest. The lens holds the state and its government layer, the armed forces, the Mina al-Ahmadi terminal, and the Cooperation Council and basing relationships.
- Bahrain15 recordsSmall, and diplomatically weighty out of proportion to its size. The lens holds the state and its government layer, the armed forces, the Sitra terminal, and the basing relationship that puts the US Fifth Fleet and the combined maritime commands on its territory.
- Oman15 recordsThe mediation channel of record, and the one Gulf Arab state whose exports leave outside the strait. The lens holds the state and its government layer, the armed forces, the Mina al-Fahal terminal on the Gulf of Oman, joint operation of the strait's traffic scheme, and the diplomatic relationship with Tehran that the others do not have.

Backgroundwhy this matters, and the conflict in 6 points
Why it matters
About a fifth of world petroleum liquids consumption and roughly a third of global crude oil trade moves through the Strait of Hormuz, along with close to a fifth of the world's liquefied natural gas. Every alternative route combined carries a fraction of that, and for LNG there is no alternative at all. What happens in this system reaches household energy bills, shipping costs and industrial supply chains on other continents.
The conflict in five minutes
6 points, composed from this conflict’s own sourced records — nothing here is a new claim.
One waterway carries the region's exports, and there is no second one
Roughly 20 million barrels a day of crude and products pass the Strait of Hormuz — about a third of global crude oil trade — along with close to a fifth of the world's LNG. Every pipeline bypass combined moves a fraction of that, and for liquefied gas there is no fixed bypass at all.
A strait can close commercially while staying physically open
Iran declared the strait closed on 28 February 2026 and it was never sealed. What stopped the traffic was the withdrawal of marine war-risk cover a week later. Legal access, physical access and commercial access are three different things in this system, and they have moved independently throughout the war.
An interstate war has been running since 28 February 2026
United States and Israeli strikes on Iran opened that day and Israel killed Supreme Leader Ali Khamenei. Iran has struck all six Gulf Arab states. The United States and Israel are participants in this system, not observers of it.
Iran has three parallel armed structures, not one military
The Artesh, the Revolutionary Guard and the Law Enforcement Command each answer to the Supreme Leader in parallel; the Armed Forces General Staff is the apex staff that coordinates them, not a fourth force beside them. Iran runs two separate navies with different missions in the same sea, and understanding which one a report means is usually the difference between reading a Gulf incident correctly and not.
The Gulf states are not a bloc, and their responses have diverged
Six states share one waterway, one institution and one exposure, and answered the same war differently. Two have signed defence arrangements outside the Gulf Cooperation Council since it began.
Nobody can currently verify what Iran's nuclear programme is doing
The IAEA stopped verification activities on 28 February 2026 and is denied access to twenty declared sites. That absence is the dominant fact on the file, and it is evidence for neither suspension nor continuation.

Iran–Gulf developments — 18 October 2026
Strikes in the strait went on at their October pace, and the attacks spread. A container ship struck on 13 October sank the next day, the second large ocean-going ship confirmed sunk in the war. Tankers were reported struck off Saudi Arabia's Gulf coast at Al Jubail, and Iran's navy told ships east of the strait to coordinate with it. UKMTO counted combined transits about 70 per cent below pre-war. It said most attacked ships no longer report, so its count is a floor. No cover was found written, and nothing changed in the IMO's view or the legal régime. On the Saudi front, Houthi missiles reached the Yemeni government's seat in Aden. The Security Council, in a presidential statement, affirmed Saudi Arabia's right of self-defence; the statement authorises nothing. Egypt offered to defend the kingdom if asked, outside the Makkah Agreement, and no force was attributed to that agreement. Nothing between Washington and Tehran is in force. The IAEA's pages could not be read, and verification access was not reviewed.
Who commands Iran's war? Coordination is on the record. Command below the top is not
Iran is fighting with two armed forces — the Revolutionary Guard and the regular army, the Artesh. One joint headquarters announces their operations, and on 8 April one order in the Supreme Leader's name told every branch to cease fire. Between that order and the forces, the public record shows coordination: a headquarters that speaks for both, a strait divided between two navies, two strike campaigns each run and claimed by its own service. It does not show any headquarters tasking, redirecting or restraining both — and in August the Leader ordered the joint headquarters merged into the General Staff.

Zone legend — Sea areas and strategic geography
Every zone in this module is a SEA AREA. There is no land zone here, and that is deliberate: the analysis is about access to water and to fixed installations, not about who holds ground. The three areas show the enclosed Gulf, the approaches to the Strait of Hormuz and the open-ocean side beyond it — broad, generalised orientation geometry that never depicts naval positions, patrol areas, transit routes, minefields or strike zones. Crucially, no shading here states whether the strait is open: legal, physical and commercial access to that water have moved separately through this war, and a single fill cannot carry three different answers.
- The Gulf — The enclosed Gulf — the sea into which six of the seven core states load their exports, with one outlet. As of 2026-09 · Confidence: High.
- Strait of Hormuz approaches — Strait of Hormuz approaches — the water every Gulf cargo but Oman’s must cross. Not a depiction of whether it is open. As of 2026-09 · Confidence: Moderate.
- Gulf of Oman approaches — Gulf of Oman approaches — the open-ocean side of the strait, and what any genuine bypass has to reach. As of 2026-09 · Confidence: High.
Watch 10 standing questions on Iran–Gulf — 3 moved in the current review window, last reviewed 2026-10-18.All 10 Watch questions
- Does nuclear diplomacy move from signalling to implementation?
- Does the Makkah Agreement become an operational defence mechanism?
- Is Bab el-Mandeb still usable, and for whom?
- Who attacked Ras Tanura?
- Has the IAEA regained meaningful verification access?

Whether the sanctions position changes, and in which system
Watch the three legal systems separately, because they are separate: the United Nations measures that returned under the snapback, the European Union restrictive measures reimposed by Council decision on 29 September 2025, and United States measures including General License U of 20 March 2026 authorising certain Iranian petroleum transactions. The baseline is that all three are in force and were not adopted together. The change that would count is an amending instrument in one of them — and a change in one system is not a change in the others, which is why a sanctions headline is never a status for the file as a whole.
Whether the multinational maritime mission changes character
Watch for a change in the stated mandate of the Combined Maritime Forces or in its 47-nation membership. The baseline is a partnership whose stated mission is against illicit non-state actors, headquartered in Bahrain, commanded by the same officer who commands the United States Fifth Fleet and NAVCENT — and which is not a party to the interstate war on that account. The change that would count is a formal mandate change or a member's declared withdrawal. The shared commander is an institutional fact and not evidence of a merged mission, and this module does not treat coalition activity as belligerent activity.

Scope of this coverage. This module describes a regional system, and that system is currently operating under active interstate war conditions: a United States and Israeli strike campaign against Iran began on 28 February 2026 and was continuing at the time of writing, with Iranian strikes on all six Gulf Arab states and sustained disruption to the Strait of Hormuz. Vigil covers that war as events, campaigns and disruptions inside the system — not as the module's subject, and not as a war tracker. Nothing here forecasts the conflict's course.
