Global oil supply shrank by 1.8 million barrels per day in April, the International Energy Agency reported Wednesday. The cumulative daily loss since February now stands at 12.8 million barrels as the Strait of Hormuz remains restricted by the Iran war. Brent crude held above $107 per barrel, and the IEA warned that an extended closure could push prices high enough to destroy a historically large amount of demand.
The losses are not theoretical. They are draining the world's emergency buffer at a speed the IEA called "a record pace."
"With Hormuz tanker traffic still restricted, cumulative supply losses from Gulf producers already exceed 1 billion barrels," the agency stated in its May oil market report, as cited by Global News Canada. The strait is the narrow throat through which roughly one-fifth of the world's oil passes. It has been effectively closed to normal tanker traffic since February, when the conflict between the United States and Iran escalated into direct military confrontation.
Three months in, the economic machinery that depends on that oil is starting to seize. Chinese, Japanese, Korean, and Indian oil imports have dropped sharply. The IEA report noted that "end users"—factories, shipping companies, power plants—are cutting consumption.
Higher jet fuel costs have grounded flights. Aviation activity is running "below normal level," the agency said. That is the demand side.
On the supply side, a handful of producers have stepped into the breach. Canada, the United States, Brazil, Kazakhstan, Venezuela, and Russia all increased crude exports, the IEA noted. But the math does not add up.
The new barrels are not arriving fast enough to replace what the Gulf cannot ship. The price signal is already flashing. Brent crude, the global benchmark, was trading around $107 per barrel on Wednesday.
That is well above pre-war levels. A separate IEA report published in March, cited by Global News, projected that if the war drags into June, prices could breach $200 per barrel. What does $200 oil mean at the pump?
Roughly $7 per gallon for American consumers. For a family filling a 15-gallon tank once a week, that is $420 a month just on gasoline. The policy says one thing.
The reality says another. Both sides claim progress toward a peace deal. The IEA report described the diplomatic signals as "conflicting," which has led to "wild swings" in benchmark prices throughout April.
Traders are pricing in hope one day and catastrophe the next. If a deal were reached today—allowing the Strait of Hormuz to reopen for oil tanker traffic—the IEA predicts demand would swing back to growth by the third quarter. July.
August. September. But the supply recovery would lag. "Supply of oil will likely be slower to recover," the report stated.
That mismatch matters. It means even a peace deal would not bring immediate relief at the pump. Prices would stay volatile, particularly heading into the summer months when global energy demand peaks.

Air conditioners in Phoenix and factories in Guangzhou all pull from the same constrained pool. The IEA's warning carries weight because the agency is not an advocacy group. It was founded in 1974 after the Arab oil embargo to advise industrialized nations on energy security.
Its reports shape decisions in Washington, Brussels, Tokyo, and Beijing. When the IEA says inventories are depleting at a record pace, governments listen. Behind the diplomatic language lies a stark timeline.
The March report, which Global News also cited, laid out the scenario in plain terms: if the war continues for three more months, "that would see talk quickly turn to global recession, as the world experiences a substantial market risk off."
A global recession triggered by an oil shock is not abstract history. It happened in 1973. Each time, the Strait of Hormuz was at the center of the crisis.
Each time, working families absorbed the blow through lost jobs and higher prices. This time, the global economy entered the crisis already weakened. Central banks had spent two years fighting inflation.
Household savings were depleted. Governments were carrying heavy debt loads from pandemic-era spending. The margin for error was thin before the first tanker stopped moving.
Canada's role as a swing producer has grown more prominent. The IEA specifically named Canada among the countries increasing crude exports. For Alberta's oil sands, high prices make expensive extraction profitable.
But pipeline capacity remains a bottleneck. Canadian oil cannot reach global markets fast enough to fully capitalize on the supply gap. The same constraint applies to U.S. shale producers.
They can increase output, but not instantly. Wells take time to drill and complete. The Permian Basin is not a tap you can turn on and off.
The IEA's warning that supply will be "slower to recover" even after a peace deal reflects this physical reality. Why It Matters: The Strait of Hormuz closure is the single largest disruption to global energy markets since Iraq's invasion of Kuwait in 1990. If the conflict persists through the summer, the economic consequences will cascade: higher transportation costs feeding into food prices, reduced industrial output triggering layoffs, and central banks forced to choose between fighting inflation and supporting growth.
The last time oil breached $140 per barrel in 2008, it helped tip the world into the worst recession in generations. This disruption is already larger in volume terms. - Global oil supply losses total 12.8 million barrels per day, with cumulative Gulf producer losses exceeding 1 billion barrels since February. - Brent crude is trading above $107 per barrel, and a March IEA report projected a potential breach of $200 if the war extends into June. - Even if a peace deal is reached immediately, oil supply will recover more slowly than demand, keeping prices volatile through the summer. - The IEA warned that an extended strait closure could destroy enough demand to trigger a global recession. What comes next is a race between diplomacy and depletion.
If a peace deal materializes by then, demand rebounds but supply lags, creating a different kind of price pressure. If no deal emerges, the $200-per-barrel scenario moves from projection to reality. The next IEA monthly report will show whether April's 1.8 million barrel daily loss was a peak or a plateau.
Either way, the world's oil cushion is getting thinner by the day.
