IEA Raises Oil Shortfall Estimate to 1.8 Million Barrels
The global oil market shortfall for the third quarter is now put at 1.8 million barrels a day, about a million more than the International Energy Agency estimated in July.
The world oil market could run short by as much as 1.8 million barrels a day in the third quarter of this year, according to the International Energy Agency’s monthly oil market report, published on August 12. The same agency had put the gap at around 800,000 barrels a day in its July report, meaning the estimate worsened by roughly a million barrels a day in a single month.
The figure describes the gap between what the world consumes each day and what gets pumped and delivered, a difference that has to be covered from stockpiles. A swing of that size within one month rarely comes from the demand side, since consumer habits do not shift that fast. It comes from supply.
Middle East oil production in July ran 8.3 million barrels a day below its pre-war level, a shortfall larger than the annual output of many individual cartel members on its own, and it sits at the core of the whole calculation.
Why the estimate got a million barrels worse
The agency’s report lists four supply disruptions running in parallel:
- difficult passage through the Strait of Hormuz, still the main factor
- the American blockade of Iranian exports
- attacks on ships in the Bab el Mandeb strait
- reduced exports of Kazakh oil
None of these four channels responds to price. When a tanker cannot pass safely, a higher price does not open the route, so the usual mechanism, where pricier oil pulls fresh supply onto the market, simply does not work here.
Stockpiles draining, refining slipping
Global oil stocks have fallen by about 410 million barrels since the Middle East war began. That number is the real measure of how long the market can absorb a 1.8 million barrel daily shortfall without another price spike, since it is stockpiles that cover the gap. At the pace the report describes, 1.8 million more barrels leave tanks and vessels each day than arrive, and every barrel drawn down narrows the cushion available for the next disruption in supply.
The other end of the chain is narrowing too. Global crude refining in July ran five million barrels a day below the same month a year earlier, and Russian refinery throughput fell to its lowest level in nearly two decades because of Ukrainian strikes. The shortage is thus shifting from crude oil onto diesel, gasoline and jet fuel, the products the end buyer actually pays for.
What the report projects for 2026 and 2027
For this year the agency expects global oil supply to fall by 4.3 million barrels a day and global demand to fall by 1.6 million barrels a day. Both figures are negative, but supply is dropping almost three times faster, and that gap is the source of the shortfall: consumption is pulling back more slowly than supply.
For 2027 the report offers a different picture, tied to an explicit condition that is political rather than market driven. If the conflict in the Middle East eases and exports return to normal, supply could exceed demand by 4.6 million barrels a day. In that scenario global demand rises by 2.4 million barrels a day while global supply rises by 8.3 million, more than three times as fast.
Brent crude was trading around $88 a barrel on August 12. After the strike on a tanker in the Strait of Hormuz, which we reported on earlier, the price had crossed $84, so the current level is a continuation of that same move rather than a fresh break. The agency’s next monthly report will show whether the third-quarter shortfall estimate shifts again, and in which direction.
