The Closure
At precisely 7pm on the evening of 6 April 2026, the lights dimmed in shopping malls across Bangladesh . Not because of power cuts — though those would come — but because the government had issued an edict that would have seemed unthinkable six weeks earlier: all shops, all cultural events, all public gatherings must end by nightfall. The measure was designed to conserve energy, to make the dwindling reserves of diesel last just a little longer. In Dhaka, traders pulled down shutters early, their frustration palpable. In the provinces, fairs that had run for generations under starlight were dismantled before dusk.
This was not an isolated response. It was part of a cascading global emergency triggered by a war that began on 28 February 2026, when the United States and Israel launched military operations against Iran . Within days, the Strait of Hormuz — the narrow waterway through which a fifth of the world's oil supply flows — became a battleground. The International Energy Agency would later call it the largest supply disruption in the history of the global oil market . Oil prices vaulted above US$100 a barrel almost immediately . By early April, the world was not merely experiencing a price shock. It was staring at the possibility of running out.
The Philippines declared a national energy emergency . European airports warned that jet fuel shortages would become acute within three weeks if supplies did not resume . In Britain, petrol prices climbed above 150 pence a litre, and more than 400 stations ran dry of at least one fuel grade . In Kenya, matatu drivers announced a 25 per cent fare hike, effective 15 April . In Thailand, fuel price boards at petrol stations became objects of daily pilgrimage, each update a small verdict on the day's fortunes . And in Australia, a government that had never before invoked its emergency fuel powers now halved the excise and paused road charges for lorries, buying time in three-month increments .
This is the story of those three weeks, and of the fragile systems they exposed.
The Choke Point
The Strait of Hormuz is 21 miles wide at its narrowest point. On a clear day, you can see from Oman to Iran. For decades, this sliver of water has been the world's most critical energy chokepoint, a fact that has shaped the strategy of navies, the rhetoric of presidents, and the insurance premiums of tanker fleets. Roughly 21 million barrels of oil pass through it every day, along with vast quantities of liquefied natural gas bound for Asia.
When hostilities broke out on 28 February, the waterway did not close outright — that would come later — but it became uninsurable, unnavigable, and politically radioactive . Tankers that had been scheduled to load crude at Kharg Island or Ras Tanura diverted. Shipowners invoked force majeure clauses. Qatar, one of the world's largest LNG exporters, declared force majeure on its term contracts, leaving South Korea, Taiwan, and Singapore — countries that had structured their energy security around reliable Qatari supply — suddenly exposed .
The impact was not uniform. Countries with diversified supply routes, strategic reserves, and spare refining capacity had options. Those without did not. Myanmar, Vietnam, and the Philippines source upwards of 80 per cent of their oil via cargoes passing through the Strait of Hormuz, and analysts estimated they had roughly a month of storage before supplies would run out or alternate routes would have to be found . Vietnam's Ministry of Planning and Investment projected a 1.5 percentage point hit to GDP growth in 2026, assuming the conflict wound down within two to three weeks . If it did not, the damage would compound.
By the first week of April, it had not.
The Emergency Declarations
On 5 April, Philippine President Ferdinand Marcos Jr appeared on national television to announce that the country had declared a state of energy emergency . The government, he said, had secured enough crude oil supply to last until 30 June . It was a reassurance calculated to forestall panic, but it also tacitly acknowledged the precipice. The Philippines imports virtually all of its oil, and the closure of the Strait of Hormuz had severed its primary supply line. Energy Secretary Sharon Garin chose her words carefully: the country was facing a "price disruption," not yet an oil crisis . The distinction was semantic, and everyone knew it.
Marcos promised that the government would ensure "the flow of oil" and prevent hoarding . But the declaration itself was an admission that market mechanisms had failed, that the state would now have to allocate resources, ration supply, and prepare for the possibility that June 30 might come and go without relief.
Elsewhere in Asia, governments were making similar calculations. In India, which had long maintained a precarious balance between subsidising fuel for its population and sustaining tax revenues, the finance ministry slashed central excise duties on petrol and diesel . The move cushioned consumers from the worst of the price surge, but it came at a steep cost: tax revenues took what officials described as a "huge hit" . It was a gamble — using the state's fiscal capacity to buy time, in the hope that the war would be short and supply would resume before the coffers ran dry.
In South Africa, the government halved the fuel excise, a measure that would have been politically unthinkable in ordinary times . In Australia, the excise was halved and road user charges for trucks were paused for three months, an emergency intervention by a government that had never before used such powers . These were not policies. They were triage.
The Reversion to Coal
As oil became scarce and ruinously expensive, a grim substitution began. Across Asia, power plants that had spent the past decade transitioning away from coal — under pressure from climate commitments, public health advocates, and international lenders — began ramping up use of the dirtiest fossil fuel . It was a decision born of necessity, not choice. Natural gas, much of it shipped as LNG from the Middle East, was no longer arriving in the volumes required. The alternatives were coal or blackouts.
The Guardian reported that governments across the region were accelerating coal use to cover the energy shortfall . The reversal was striking not only for its speed but for its implications. A decade of climate policy, of retirements of coal-fired capacity, of investments in cleaner baseload power, was being unwound in a matter of weeks. The logic was brutal and immediate: a energy grid that could not keep the lights on would not survive to decarbonise.
Environmental advocates condemned the shift, but their objections were drowned out by the more immediate concerns of industry and households. In Vietnam, factories that had been operating on tight margins now faced the prospect of rolling blackouts . In the Philippines, the energy emergency gave the government sweeping powers to commandeer supply and prioritise allocation . Coal, for all its externalities, was available. Oil was not.
The Travellers' Dilemma
In the first week of April, airline executives convened a series of emergency meetings. The subject was not passenger demand or route profitability, but whether they would have enough fuel to fly at all. Airports Council International Europe had issued a stark warning: jet fuel shortages would become acute within three weeks if Middle Eastern supplies did not resume . The same calculus applied in the United States, where jet fuel prices had nearly doubled in some regions .
The mathematics of airline operations are unforgiving. A widebody aircraft crossing the Atlantic burns roughly 12 tonnes of fuel per hour. When fuel prices double, and supply becomes uncertain, the business case for marginal routes collapses. Airlines began weighing flight cancellations, not as a response to weak demand, but as a hedge against the possibility that fuel would simply not be available .
For travellers, the advice was blunt: book early, expect disruptions, and prepare for prices to rise further . The era of cheap long-haul travel, underwritten by abundant oil and fierce competition, was on pause. Some analysts believed it might not return.
In Britain, Asda — one of the country's largest supermarket chains, which also operates petrol stations — warned of "temporary shortages" at some locations . The word "temporary" was doing a great deal of work. With oil prices above 150p a litre and more than 400 stations dry , the shortages were not a blip. They were a symptom of a supply chain that had run out of slack.
The African Arithmetic
In Nairobi, the fuel crisis arrived not as a government declaration but as a fare hike. On 10 April, the Matatu Owners Association announced that fares would increase by 25 per cent, effective 15 April, in response to rising diesel prices . For millions of Kenyans who depend on matatus — the privately operated minibuses that form the backbone of urban transport — the increase was immediate and non-negotiable. It was also a harbinger.
Across sub-Saharan Africa, where fuel is imported, subsidised, and politically sensitive, the war in Iran exposed the fragility of energy security. The continent's ten largest economies were coping in different ways, but none had been spared . In South Africa, the government's decision to halve the fuel excise was a direct response to public pressure and the threat of unrest . In Kenya, the government allowed prices to rise and left it to transport operators to pass the cost on to commuters .
The crisis also highlighted a longer-term vulnerability. African economies, many of which are net oil importers, had made little progress in building strategic reserves or diversifying supply. When the Strait of Hormuz closed, there were no alternative pipelines, no reserve tankers waiting offshore, no spare capacity to call upon. The continent was, as analysts had long warned, structurally exposed to shocks originating in the Middle East.
The Three-Week Window
By mid-April, the dominant question in ministries, trading floors, and emergency coordination centres was not whether the crisis would worsen, but whether it could be contained before the system broke. The consensus, if one could call it that, was that the world had two to three weeks before the shortages became acute and irreversible .
CNBC's analysis was blunt: if the Strait of Hormuz was not reopened within one to three weeks, oil prices would rise dramatically and the economic damage would cascade . The International Energy Agency, in its World Energy Investment 2026 report, noted that the conflict had already forced a fundamental reassessment of energy security across Europe and Asia . The Guardian described Europe as facing "another energy crisis," a sequel to the gas shortages of 2022 but with a different script and potentially worse consequences .
The window was closing. Vietnam's projections assumed the conflict would wind down within two to three weeks; beyond that, the economic damage would be compounded and the fiscal tools available to the government would be exhausted . The Philippines had supply until 30 June, but only if current consumption held and no further disruptions occurred . Australia's three-month excise suspension was a stopgap, not a solution .
Governments were urging calm. In the Pacific, regional leaders were told to avoid panic and to coordinate their responses . But calm is a luxury afforded by the prospect of resolution, and by mid-April, there was little evidence that the war was nearing an end.
The Unravelling
What the 2026 Iran War Fuel Crisis revealed, in the span of six weeks, was how much of the world's material prosperity rests on the assumption that oil will always flow, that the Strait of Hormuz will remain open, that the supply chains built over decades of relative peace will hold. It was an assumption that had survived previous conflicts, sanctions, and even the 2022 energy shocks in Europe. But it did not survive this one.
The crisis was not merely a matter of price. Price shocks, however severe, can be weathered if supply remains available. What made April 2026 different was the conjunction of scarcity, geopolitical paralysis, and the speed with which the world's buffers were consumed. Countries that had assumed they had months of reserves discovered they had weeks. Governments that had relied on market mechanisms to allocate fuel found themselves imposing emergency rationing and invoking powers that had never been used . Airlines that had planned their summer schedules now faced the prospect of grounding fleets .
The energy transition, which had been the defining policy project of the previous decade, was now in abeyance. Coal was being burned in greater quantities . Climate commitments were being quietly shelved. The future could wait; the present was on fire.
And still the question remained: what happens if the war does not end in three weeks? What happens if the Strait of Hormuz remains closed, if Qatar's force majeure becomes permanent, if the strategic reserves run dry? No government had a convincing answer, because no government had planned for this scenario. The playbook, such as it was, assumed that supply disruptions would be temporary, that diplomatic pressure would eventually prevail, that the global economy was resilient enough to absorb a shock of this magnitude.
By mid-April, those assumptions were being tested in real time, in the queues at petrol stations in London, in the darkened shopping malls of Dhaka, in the rising fares on matatus in Nairobi, in the emergency declarations in Manila. The test was not going well.
The world had built itself on the promise of cheap, abundant energy. For three weeks in the spring of 2026, that promise was broken. And no one knew how to put it back together.
