IEA Deepens 2026 Oil Demand Fall by 1.6 Million Barrels a Day

By The Edge Research Team

World oil demand will fall by one point six million barrels a day in 2026, a deeper contraction than the one million a day it forecast in July, the International Energy Agency said in its Oil Market Report published on Wednesday, pointing to the continuing closure of the Strait of Hormuz and the high fuel prices that have followed it. The agency described the revision as five hundred and ten thousand barrels a day, which does not reconcile exactly with its two published annual figures because both are rounded.

The contraction eases as the year runs down. Measured against the same quarters a year earlier, demand fell by four point nine million barrels a day in the second quarter and is forecast to fall by two point eight million in the third, before returning to growth of five hundred and eighty thousand barrels a day in the final three months. For 2027 the agency projects demand expanding by two point four million barrels a day, an upgrade from the two million it forecast in July.

The July balance in that table is as the agency restated it this month, not a figure calculated here.

Supply is the tighter side of the ledger. Global production rose by two point four million barrels a day in July to one hundred and one point five million, but remained six point three million below its level a year earlier, with eight point three million barrels a day of Gulf output still shut in. Gulf production itself rose two point five million barrels a day in July to twenty three point nine million, still eight point three million below pre-war levels, while regional exports including routes bypassing the Strait of Hormuz fell two point one million barrels a day to fifteen million. The agency cut its third quarter supply projection by a further one point seven million barrels a day against last month’s report, which it attributed to renewed hostilities and maritime disruption in July and early August. Across 2026 it now expects supply to decline by four point three million barrels a day on average, before rebounding by eight point three million a day next year to one hundred and ten point three million.

The near term balance has tightened sharply. The agency expects a deficit of one point eight million barrels a day in the third quarter, more than double the estimate of around eight hundred thousand barrels a day it published last month. It also said inventory buffers are depleting rapidly and that the urgency of reopening the strait has increased, while projecting that the market returns to surplus towards the end of this year.

Stocks are where the strain is showing. Global observed inventories fell by sixty nine million barrels in July, a rate of two point two million barrels a day, dragged lower almost entirely by a drop in oil on water as exports from the Gulf and the Caspian Sea were disrupted again. Onshore stocks fell by a more modest six million barrels, as the pace of the agency’s emergency stock releases by member countries slowed and despite continued draws on Chinese crude. Total observed stocks ended July below seven point nine billion barrels, the first time under that level since April 2025. Cumulative draws between the end of February and the end of July reached four hundred and ten million barrels, an average of two point seven million barrels a day.

Prices moved violently through the month. Benchmark crude traded in a range of almost forty dollars a barrel, which the agency called exceptional, after the breakdown of the mid-June ceasefire reversed the recovery in Gulf supply. Prices spiked as high as one hundred and five dollars a barrel on 23 July. Prompt differentials for both West Texas Intermediate and Brent futures returned to backwardation, the pattern in which nearby barrels command a premium over later ones. North Sea Dated rose by twenty five dollars and sixty seven cents over July to end the month at ninety six dollars and eighty cents, and was trading at around ninety two dollars when the agency wrote.

Refining and product trade carry the clearest signs of physical disruption. Crude throughputs ran at eighty point nine million barrels a day in July, nearly five million below a year earlier, and continued Middle East product export disruption and attacks on Russian refineries cut third quarter run estimates by a further three hundred and seventy thousand barrels a day. Seaborne product trade fell three point eight million barrels a day against a year earlier even as United States exports rose seven hundred thousand. Diesel exports from Russia, the Middle East and Asia were one point three million barrels a day lower, which the agency put at about twenty percent of global seaborne trade, and jet fuel exports from those regions fell around six hundred and seventy thousand barrels a day, which it put at thirty four percent of global trade. Tighter light and middle distillate markets pushed cracks and margins in the Atlantic Basin to record highs, and the agency said margins have gone on setting records in Europe in August.

Why it matters: Read only through the deficit, this is a scarcity story. Read through the whole report, it is a story about timing. In the same document the agency deepened the 2026 demand decline, raised 2027 demand growth from two million barrels a day to two point four million, and said the market returns to surplus towards the end of this year. Setting those three together is this publication’s reading rather than the agency’s characterisation, and what they describe is a market on a path back to normal. The harder number is the buffer. Inventories have supplied four hundred and ten million barrels since February and now sit below seven point nine billion for the first time since April 2025, and the agency has said in its own words that those buffers are depleting rapidly and that the urgency of reopening the strait has increased. A forecast surplus several months out is of limited use to a refiner drawing on stocks now.

Looking ahead: The forecast turns on when the eight point three million barrels a day of shut-in Gulf output returns and at what pace, since the projected surplus depends on supply recovering. Before that, the observable markers are the monthly stock draw against July’s two point two million barrels a day, whether observed inventories stabilise near seven point nine billion barrels, and whether Atlantic Basin refining margins hold at record levels or ease as throughputs recover. The agency publishes its next report in September.
