The Strait Closed. Three Billion People Paid the Price.

A handwritten sign appeared on a restaurant door in Bengaluru. It read: No roti today — due to the gas cylinder crisis caused by the war between Iran and the USA. Thousands of miles from the nearest missile strike, a cook in southern India couldn't light his stove.

That sign is not an anecdote. It is a dispatch from a new kind of war damage — one that doesn't show up in military casualty counts.

Since US and Israeli strikes on Iran began on February 28, the Strait of Hormuz has been effectively closed. What followed was not just an energy shock. It was a slow-motion detonation spreading across the kitchens, classrooms, hospitals, and fields of the Global South — touching an estimated 3.2 billion people.

A 21-Mile Chokepoint That Runs the World

At its narrowest, the Strait of Hormuz is just 21 miles wide. Before the war, it carried 20 percent of global oil, 20 percent of liquefied natural gas, a third of seaborne fertilizer, and nearly half of the world's sulfur exports. Since the closure, commodity shipments through the Strait have fallen by 95 percent.

The downstream effects arrived fast. Sri Lanka declared every Wednesday a public holiday to conserve power. Laos cut its school week to three days. Egypt ordered shops and cafes to close by 9 pm. Thai government workers were told to take the stairs. South Korea's president asked citizens to take shorter showers. These are wartime policies — in countries that are not at war.

The pattern is consistent and telling: governments across Asia, the Middle East, and Africa are rationing not just fuel, but the basic rhythms of daily life.

The Food Crisis Is Already Here

India imports much of its cooking gas — LPG — through the Strait. When the route closed, black-market prices for a single household cylinder nearly tripled. A 70-year-old Mumbai institution slashed its Ramadan menu to four dishes. A chain stopped serving dosa because the dish requires an open gas flame. In Tamil Nadu state alone, nearly 10,000 restaurants face closure.

The fertilizer shock is slower but potentially more severe. The Gulf produces roughly a third of the world's urea exports — a critical ingredient in crop fertilizer. The closure hit at the worst possible moment: just as Northern Hemisphere farmers needed to apply fertilizer for spring planting. Bangladesh shut down four of its five state-owned urea plants. Nepal, which produces no chemical fertilizer domestically, saw urea prices jump 40 percent ahead of its paddy season.

The World Food Programme now warns that 45 million more people globally could be pushed into acute food insecurity — a 15 percent increase on current hunger levels. To make things worse, vital UN food aid is stranded in warehouses in Dubai, unable to reach the people who need it most.

The Coal Comeback Nobody Wanted

The energy gap is being filled with the dirtiest available option. Japan is lifting restrictions that required its oldest coal plants to run below 50 percent capacity. South Korea removed its seasonal coal power cap and delayed retirement of three coal plants. Thailand, the Philippines, and Indonesia are all expanding coal operations. Germany is reviewing whether to restart mothballed coal plants.

Coal companies are thriving. Australia's Yancoal is up 40 percent since the war began. Pennsylvania-based Core Natural Resources is up 30 percent. The deeper problem is structural: once coal plants are switched on, they become politically difficult to shut down again. Short-term crisis management risks becoming long-term carbon lock-in — precisely the trajectory climate scientists have spent years warning against.

India, meanwhile, formally permitted restaurants and hotels to burn wood, dried crop waste, and cow dung as fuel — reversing years of clean-fuel progress in a single directive.

The Unexpected Green Upside — And Its Limits

There is a counternarrative, and it deserves to be heard. In Nepal, over 70 percent of new car sales are already electric. Electric rickshaws are selling out in Pakistan. BYD, the Chinese electric vehicle maker, now projects overseas sales to be 15 percent higher than pre-war forecasts. One energy analyst called this "Asia's Ukraine moment" — the idea that a supply shock, like Russia's invasion did for European wind and solar, could accelerate Asia's clean energy transition.

It's a plausible theory. Energy crises have historically been among the most powerful catalysts for structural change. The 1970s oil embargo helped birth the modern solar industry. Russia's 2022 invasion reshaped Europe's energy map within two years.

But the analogy has a hard limit. Europe had the capital, infrastructure, and institutional capacity to pivot quickly. Much of the Global South does not. And a transition measured in decades offers cold comfort to the 45 million people who may go hungry in the months ahead.

Who Pays for Wars They Didn't Start?

The deeper story here is about distribution — of power, of risk, and of cost. The governments that ordered the strikes on Iran will not ration their school weeks. Their restaurants will not close for lack of cooking gas. Their farmers will not go without fertilizer at planting time.

The 3.2 billion people now subject to some form of fuel rationing, power cuts, or energy restrictions had no seat at the table when this war was decided. They are not combatants. They are not even bystanders in any meaningful sense. They are simply downstream — geographically, economically, and politically — from decisions made elsewhere.

That is not a new dynamic in geopolitics. But the Hormuz closure has made it unusually visible, and unusually measurable.
