Conflict over the Strait of Hormuz threatens world food production
The strait has been closed since March 2026. Oil found other ways out. Fertiliser, gas and helium did not, and the damage to next year's harvests is still arriving. This page shows what happened, and lets you try to change what comes next.

I · before oil
The Gulf is a young sea, about fifteen thousand years old, shallow and saltier than the ocean, with one kind of mangrove, dugongs, turtles and oyster beds. In 1907 the pearl fleet was 4,500 boats and 74,000 men. A diver went down on half a pound of dates and coffee, a horn clip on his nose, forty to seventy-five seconds a plunge, fifty plunges a day. The Gazetteer of that year said that if the pearls failed, the ports of the Trucial coast "would practically cease to exist". Up the Shatt al-Arab, fifteen million date palms were watered twice a day by the tide: "The tides do the rest." Gertrude Bell, in the flood of 1916, saw "a solitary buffalo, knee-deep in mud and water, eating the reed tops". In 1900 Abadan was "a few peasant hamlets and a scattering of palm groves".

II · the first oil, 1901 → 1953
On 26 May 1908 a well at Masjed-e Soleyman struck oil, the first in the Middle East. The man asleep beside the rig was a 23-year-old lieutenant who wrote to his father that day what the oil was for. The concession had been signed seven years earlier by a shah and a Queensland gold millionaire who never went to Persia. Six years later the British government bought control of the company, for the navy. The people below are the ones the record names, in the words the record keeps.

III · how it arose, 1901 → 2026-02-27
Iran's oil industry is the oldest in the Middle East. The strait carried oil for a century before it was closed. Below are forty dated points from the first concession to the night before the strikes. Nine are forks: a moment when a different course was argued, at the time, by someone in a position to take it. Each fork shows what was chosen, the alternative in the words of those who proposed it, and what followed. The page does not say which was right.

US ceases participation in the JCPOA; E3 say they will remain
what was said and done
White House fact sheet (8 May 2018): "The Iran Deal was one of the worst and most one-sided transactions the United States has ever entered into"; the deal "failed to deal with the threat of Iran's missile program", lacked "a strong enough mechanism for inspections and verification", and had sunset provisions. CRS: "In May 2018, President Donald J. Trump issued a memorandum stating that the United States would no longer participate in the JCPOA and would reimpose sanctions that had been suspended pursuant to the agreement." E3 leaders (8 May 2018): "It is with regret and concern that we, the Leaders of France, Germany and the United Kingdom take note of President Trump's decision to withdraw"; they would "remain parties to the JCPoA"; it "remains important for our shared security"; they urged Iran to "show restraint in response to the decision by the US" and to "continue to meet its own obligations under the deal, cooperating fully and in a timely manner with IAEA inspection requirements."
the alternative on the table
The E3 statement of the same day is the contemporaneous alternative: stay in the deal, keep the inspections. This is the fork the brief's example points at, with both branches voiced on the day.
what followed
"Beginning in July 2019, the IAEA verified that some of Iran's nuclear activities were exceeding JCPOA-mandated limits" (CRS); the E3 date Iran's non-implementation from "May 2019" (E3, 28 Aug 2025).

IV · space
The strait is about 21 nautical miles wide at its narrowest; the two shipping lanes lie in Omani waters. Before the war roughly 20 mb/d of oil and a fifth of the world's LNG went through it, most of it bound for Asia.
width and lanes: pending the history pass · 20 mb/d: EIA STEO 4Q25 21.6, IEA about 20 · LNG share: IEA, EIA, CRS · destinations: EIA
Two pipelines get oil out without the strait: the East-West line to Yanbu on the Red Sea, and ADCOP to Fujairah on the Gulf of Oman. Qatar's gas has no pipeline. It has the strait or nothing.
East-West about 7 mb/d (Saudi Ministry of Energy); Yanbu loading limit 4.5 mb/d (Vortexa); ADCOP 1.5 to 1.8 mb/d (disputed); LNG no bypass (EIA)
V · the record, 2026-02-27 → today
Tanker transits fell from about 37 a day to 1.0. Brent spot went from $71.32 to $138.21 on 7 April and back to $96.02. The US reserve fell from 415.4 mb to 287 mb.

VI · four clocks
VII · the spread
The war did not stay in the strait. On 20 July the Houthis declared a blockade of Saudi shipping in the Red Sea, the route Yanbu depends on. On 24 August a Saudi tanker was hit off Yanbu. Between 10 and 14 September they took Mokha, Mayun and the Hanish islands at the southern gate. On 11 September drones launched from Iraq's Maysan province cut the East-West pipeline itself, and Saudi Arabia shut it. It restarted at a low rate on 22 September. Every way out of the Gulf is now an edge that can be closed.

VIII · the allies and the war
Readers ask why NATO did not join. The record answers in the allies' own words. No North Atlantic Council statement on the strikes was found; the alliance's recorded acts were shooting down a missile bound for Turkish airspace on 4 March and, in July, one sentence calling on Iran "to fully respect freedom of navigation in the Strait of Hormuz". Germany's spokesman on 16 March: "NATO is an alliance for the defence of territory"; the Prime Minister of the United Kingdom the same day: "it's never been envisioned to be a NATO mission"; the Secretary General in July: "NATO itself is not involved. This is outside NATO territory", while counting "between 4000 and 5000 flights taking off from European bases". Canada's Prime Minister on 4 March: "We were not informed in advance, we were not asked to participate." No actor says there was too little time. The one government that addressed its own timing said its decision not to take part "was deliberate". Washington's account, and the votes in Congress, are in the tabs.

“by the middle of July, the full extent of temporary buffers will have been exhausted, with an overall market adjustment of 7.1 mb/d ... crude prices could be $120 a barrel. Once markets expect the temporary buffers will be exhausted, the market price could rise to nearly $150 per barrel”

X · who bears it
The strait is in the Gulf. The cost lands where food is already short, fuel is imported, reserves are thin, and the next blow is already forecast: NOAA declared an El Niño advisory on 10 September. Below, one row per country and one mark per stress the record can show, each with its series, source and date, at the week you have scrubbed to. The count is not a score. It is how many of the sourced layers have crossed a stated line. The strip in the dock is the same board, week by week: watch who crosses.
