The Cascade
Oil is the visible dependency. Helium, bromine, aluminium, fertiliser, sulphur, shipping insurance — these are the invisible ones. Every one of these dependencies was known. None was fixed. The Iran war did not create them. It made them visible. That is the difference between a crisis and a revelation.
I. The Chokepoint
The Strait of Hormuz is 33 kilometres wide. The shipping lane is 3 kilometres wide. Through these 3 kilometres flows 20 per cent of the world’s shipped crude oil, a fifth of the global liquefied natural gas trade — and a range of other raw materials and substances whose significance is only now entering public awareness.
Since 28 February 2026, the Strait of Hormuz has been effectively closed to normal commercial traffic — not by mines or a naval confrontation, but by risk. Iranian drones and missiles have struck more than a dozen commercial vessels. Insurers have cancelled their policies or repriced them at levels many operators cannot afford. The result: over 200 ships drift waiting in the region. World trade has stalled.
What follows is not a simple oil crisis. It is a cascade — a series of overlapping supply shocks hitting industries nobody had connected to the Persian Gulf: semiconductor production, agriculture, medical technology, artificial intelligence.
II. The Commodities of Invisible Dependency
Qatar produces a third of the world’s helium as a by-product of natural gas processing. QatarEnergy stopped production at the Ras Laffan complex on 2 March, after the facility was struck by Iranian attacks — and declared force majeure to all customers four days later. Recent reports speak of “extensive” damage requiring years to repair and permanently reducing helium exports by 14 per cent. The spot price has doubled within a week.
Helium is not replaceable. It forms over billions of years through radioactive decay in the Earth’s crust. What escapes into the atmosphere leaves the Earth for ever. It cools the superconducting magnets in MRI machines. It is indispensable for semiconductor manufacturing — for etching the wafers on which the chips are made that power AI data centres. South Korea, which produces two thirds of the world’s memory chips, sourced 65 per cent of its helium from Qatar.
Less well known than helium, but equally critical: Israel and Jordan together produce around two thirds of the world’s bromine. Bromine is another indispensable material in semiconductor manufacturing — used in etching processes and not substitutable at short notice. Israel’s military engagement in the ongoing war endangers not only Israeli production through security risks but also export logistics through the closure of sea routes.
The Middle East accounts for around 8 per cent of global aluminium capacity. Several producers have declared force majeure. The aluminium price reached a four-year high of $3,544 per tonne in March 2026 — analysts at ING consider $4,000 realistic if disruptions persist. Aluminium is a base material for electronics, vehicle manufacturing, packaging and construction.
Qatar is one of the world’s largest fertiliser producers — urea, ammonia and other nitrogen compounds are produced as by-products of gas processing. With the halt of Ras Laffan production, these exports also ceased. The UN Economic and Social Commission for Asia and the Pacific warns of fertiliser shortages threatening crop yields in South Asia — a region of nearly two billion people. Fertiliser prices have risen 35 per cent since the end of February. The planting season is running — in many parts of Asia it is now.
Sulphur, also a by-product of hydrocarbon processing, is indispensable in copper processing, agriculture and numerous chemical processes. The interruption of gas processing in the Gulf withdraws sulphur quantities from the market for which there is no short-term alternative.
This is the most invisible and perhaps most consequential dependency: war-risk insurance has been cancelled or repriced at prohibitive levels. Without insurance, no commercial vessel sails. The blocking effect arises not from a naval blockade but from the risk calculations of the insurance industry. Freight costs for supertankers are reaching all-time highs. Ships are diverting via the Cape of Good Hope — that extends transit time by 10 to 14 days and raises costs for every cargo.
III. The Arithmetic of the Cascade
The UN estimates: oil prices up 45 per cent, gas up 55 per cent, fertiliser up 35 per cent since the end of February 2026. Regional inflation in Asia-Pacific could rise to 4.6 per cent — from 3.5 per cent the previous year. Growth in developing countries in the region could fall from 4.6 to 4.0 per cent. Behind these figures stand households eating less, businesses that cannot produce, countries trapped between inflation and recession.
The cascade does not strike evenly. It strikes hardest those who are least responsible for it: the countries of the global south that depend on food imports, the populations spending a large share of their income on energy, the hospitals whose MRI machines stand still without helium. The perpetrators — the US, Israel, Iran — bear the costs of the cascade only in the smallest part. The rest falls on people in Sri Lanka, Bangladesh, Pakistan, Vietnam.
Iran, militarily inferior, has internationalised the costs of the war. Not through an army — through a drone in front of the right chokepoint.
IV. What Was Known — and Ignored
What is disturbing about the cascade is not that it came as a surprise. It was announced — precisely, repeatedly, by institutions one could have listened to.
The Semiconductor Industry Association warned the US government in 2023: “Should the supply of helium be immediately disrupted, there would likely be shocks to the global semiconductor manufacturing industry.” That was three years before the war. Nobody acted.
The World Economic Forum, in its Global Risks Report 2026 — published in January, six weeks before the war began — explicitly pointed to the vulnerability of global supply chains through conflicts in the Persian Gulf. Nobody acted.
Helium has already experienced four major supply crises in the past twenty years — 2006, 2012, 2019, 2022. Each time the same realisation: the concentration on few sources makes the market fragile. Each time the same response: wait for the next crisis.
Trump did not process the Semiconductor Industry Association’s warning of 2023 — not because it was not available to him, but because it could not be converted into dollars and yielded no deal. He made sun and rain: oil pressure, escalation, military superiority. But he forgot the wind — as Donald Trump as Schulze Hoppe — on the empty ears of total control describes. The wind — these are the invisible dependencies that produce no headline until they fail. The empty ears are called this time: semiconductor shortage, MRI shutdown, hunger crisis in South Asia.
This is not ignorance. It is structural short-sightedness — the same pattern described in our essays on Europe’s energy dependency on Russia, on rare earth dependency on China, on software dependency on American platforms. The dependency is known. The costs of diversification are real and immediate. The costs of dependency are hypothetical and future. So the dependency remains.
V. The Structure of the Blind Spot
There is a reason these dependencies are not fixed — and it is not stupidity. It is rationality in the wrong time horizon.
A company sourcing helium from Qatar does so because it is cheaper than from Wyoming or Russia. Diversification would cost money immediately — and deliver benefits that may never materialise. For the quarterly report, that is not an attractive calculation. So one stays in Qatar.
A state that does not diversify fertiliser imports from the Gulf does so because diversification costs political capital — for a benefit that may not be visible in the next electoral term. So the dependency remains.
The cascade is the bill that always comes for someone else. Until it comes. And then it comes for everyone — but hardest for those who have insured themselves least against it.
VI. What the Cascade Teaches
The ark is built when the flood is here. That is the pattern described elsewhere. But some arks take years — not weeks. Helium sources in Wyoming, Canada, Tanzania and South Africa exist. They are at various stages of development. But exploration to production takes years. The cascade is hitting now. The alternatives are available in three to five years. Between them lies a gap that nobody can fill.
That is the real price of structural short-sightedness: not that the crisis comes — crises always come. But that the response time is shorter than the adaptation time. The damage arises in the gap.
What should follow — and should follow every crisis, but does not — is strategic raw materials policy: stockpiling of critical materials, active diversification of supply chains, investment in alternatives before they are needed. That costs. It costs less than the cascade.
The Strait of Hormuz does not only control the oil. It controls the chips on which AI computes. The magnets with which doctors diagnose. The fertiliser with which farmers sow. The world knew this. It bet that it would be fine. The bet is lost.
