Was the Strait of Hormuz closed, or repriced cargo by cargo?
Repriced cargo by cargo: by mid-2026 LNG kept under a tenth and crude under a quarter of their late-2025 flow through the Strait, and by 28 September crude, on Kpler's pre-war baseline, was back; products were not.

Was the Strait of Hormuz closed to neutral shipping?
“The Joint Maritime Information Center's Update 082 of 9 August 2026 described traffic at reduced levels across a northern Iranian-controlled route and a southern Omani corridor, and stated that neutral transit was permitted.”

Which Gulf exporters have a way to ship oil around the Strait of Hormuz?
“Only Saudi Arabia and the United Arab Emirates have operating pipelines around the Strait, on EIA's record: the 5-million-barrel-a-day East-West line to the Red Sea and a 1.5-million line to Fujairah on the Gulf of Oman.”

Who bears the economic cost of a Hormuz closure?
“On the Kiel Institute's model of a full closure, US welfare falls by 0.07 per cent while losses in South Asia and Africa are 10 to 20 times larger in percentage terms.”

Could the largest strategic oil stocks behind the Strait be released?
“The two largest strategic holders behind the Strait were not part of it. EIA estimates China's strategic stock at 1,492 million barrels in the second quarter of 2026 and India's at 21 million; neither country is an IEA member.”

Answered in: 07. A sweep of the public record found 154 parties with a stake, and more lose than gain
Geoeconomic
Who has a stake in the Strait of Hormuz?
“Rather than choose a reader, the source edition swept nine classes of the public record and found 154 parties with a stake: 59 lose, 39 gain and 56 do both.”

Answered in: 08. Gains are reported in filings and losses arrive as notices without a price
Geoeconomic
Why are the gains from the Hormuz disruption visible and the losses not?
“The asymmetry comes from disclosure rules, not from the world: a listed company must report its earnings, and nobody must price what a force majeure notice cost them.”

Facts since the research date
9 Sep 2026
EIA's September outlook forecast rising Middle East oil production as flows through the Strait gradually increase, with crude production in the region below pre-conflict averages until the second quarter of 2027. Its quarterly Hormuz table still ends at 2Q 2026.
The Joint War Committee issued JWLA-035. It keeps the Persian/Arabian Gulf area and Bahrain, Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates listed; Saudi Arabia is now listed as a country, where JWLA-033 listed its Gulf coast and its Red Sea coast excluding transits.

The US President rejected an Iranian plan to reopen the Strait within seven days, according to Al Jazeera.

28 Sep 2026
Crude through the Strait reached a seven-day average of 13.5 million barrels a day, matching the pre-war baseline, while refined products ran at 677,000 barrels a day against 3.6 million before the war; about 40 per cent of Gulf crude was bypassing the Strait by pipeline, against 17 per cent before the war. CNBC reported that US military escorts had lifted shipments. Kpler's pre-war baseline (about 17 million barrels a day of crude and products) differs from the IEA's 19.87 million for 2025; both are printed. Kpler's crude baseline (13.5) also differs from EIA's 4Q 2025 crude figure (15.9); both are printed.

Correction. The wording on monetizing the Strait is in the US Treasury's press release of 29 July 2026, not, as the source edition said, in Federal Register rule 2026-17426, whose published abstract describes the suspension of five general licences (effective 24 Aug 2026); the rule's full text could not be read on 30 September 2026.

Correction. The nine IEA members the source edition named contributed 344.5 million of the 426 million barrels; 21 further members supplied the rest, not seven. The US offer of political risk insurance was announced on 3 March, according to CRS, not on day six.

Correction. Frontline's filing describes its second-quarter 2026 profit as the best quarterly profit in its history; the source edition said best since 2004. Oil through the Strait was 21.6 million barrels a day in the fourth quarter of 2025; the source's 20.9 is the first quarter of 2025. EIA's data supplement is dated 12 August 2026, not 11 August.

Correction. Under the published 2025 time-charter war clause, the on-hire sentence covers the events in sub-clause (f); the owners' refusal sits in (b), for which the text states no hire rule. The source edition's clause plate placed the refusal under (f).

Not carried. A port-call comparison (Saudi Arabia down 15 per cent, Kuwait down 86 per cent) had no publisher traced in the source's record; a statement attributed to the Philippine labour secretary was not found on the page cited; and a second closure dated 11 June was not found in the sources read.
No new forecast is issued with these facts; a new view would be a new, separately dated forecast.
