The Organization of the Petroleum Exporting Countries (OPEC), the producer group whose secretariat publishes monthly output estimates for its members, released its August Monthly Oil Market Report on 12 August1. It puts Iran's crude production at 2,478 thousand barrels a day (tb/d) in July against a 2024 baseline of 3,257 tb/d, a gap of 779 tb/d or 24 per cent. Month on month, Iran barely moved: 2,451 tb/d in June to 2,478 tb/d in July, a rise of 27 tb/d.
Set that 27 against the same measure elsewhere in the group. Iraq added 665 tb/d over the same month and Kuwait 393 tb/d, while total OPEC+ crude production rose by 1.42 million barrels a day to 37.66 million. All four of those figures are month-on-month changes, so the comparison holds. Iran's neighbours are recovering the output the first half of this war took off them, and the loss has stayed where it fell.
A flat 2,478 tb/d does not settle the question of why it is flat. Tehran may be holding barrels back as policy, or its loading and export capacity may be physically degraded, and the figure fits either reading equally well. OPEC's table records volume and says nothing about cause, so nobody should read defeat into a number that a deliberate strategy would also produce. What sits alongside it is a state that could not hold a domestic fuel price for one night: Kerman province began selling petrol at the refinery rate on 12 August and stopped by the next morning.
Prices moved on other people's risk rather than on Iran's missing barrels. The OPEC Reference Basket (ORB) averaged $82.99 a barrel in July, down $6.76 on the month, while Brent closed at $88.52 on 14 August and $88.69 on 16 August, and West Texas Intermediate (WTI) reached $82.40 on 14 August2. Freight economics and the barrel market belong to another desk. What belongs here is the war consequence: a combatant whose export capacity has not recovered in two months, inside a group where everyone else's has.
