Iraq has warned that it could leave OPEC if the producer group does not raise its crude production quota, Reuters reported on 6 November, citing sources familiar with the matter.

The threat marks an escalation in Baghdad's long-running dispute over the share of the oil market it is allowed to supply under OPEC's output arrangement. Iraq has repeatedly produced above its official quota in recent years, arguing that its economy — heavily dependent on crude revenue — needs higher export volumes to fund reconstruction and public spending.

What the report says

According to Reuters' sources, Baghdad has signalled to OPEC that it may quit the organisation if fellow members do not agree to lift its production ceiling. The warning was delivered as the group and its allies in the wider OPEC+ coalition continue to calibrate the pace at which they unwind the voluntary output cuts put in place to support prices.

No specific quota figure that Iraq is demanding appears in the report, and OPEC has not publicly responded to the warning. The sources spoke on condition of anonymity because the discussions are private.

Why the stakes are high

Iraq holds some of the lowest-cost barrels in the world, with production concentrated in the southern fields around Basrah — Rumaila, West Qurna, Majnoon and Halfaya among them — and exports flowing largely through the Basrah and Khor al-Zubair terminals on the Gulf. Fields in the Kurdish north, tied to the Ceyhan pipeline route, have been caught in a separate standoff between Baghdad and Erbil over export arrangements and payment terms.

For OPEC, losing Iraq would remove one of the group's largest producers and complicate the supply management that the Saudi-led coalition has used to balance the market. For Iraq, departure would free output from quota discipline but strip Baghdad of influence inside the group that still sets the reference framework for roughly half the world's crude supply.

Context of the quota dispute

Iraq's frustration with its ceiling is not new. Under the OPEC+ agreements that took effect from 2023, Baghdad accepted a quota well below its stated production capacity, and it has periodically exceeded that limit, later committing to compensating cuts for the oversupply. Iraqi officials have argued the country's capacity entitlement should reflect investment already sunk into southern field expansions by operators including BP, ExxonMobil, Eni, PetroChina and Lukoil.

The reported threat comes at a sensitive moment for the group. Delegates have been debating how quickly to return barrels to the market as they gradually relax the voluntary cuts, and any move to accommodate Iraq's demand would have to come at the expense of other members' shares — a redistribution the group has historically resisted.

What to watch

The next OPEC+ ministerial meeting is the immediate checkpoint. Watch for whether the group addresses Iraq's quota demand in the communiqué, whether Baghdad sends a senior delegation, and whether any language on compensation schedules for past overproduction signals a compromise. A formal Iraqi exit process — which would require notification under the OPEC statute — would be the clearest signal that the warning has moved beyond rhetoric.

For refiners and crude traders, the practical question is simpler: a quota accommodation would mean more Basrah Medium and Basrah Heavy available to Asian and European buyers, while a rupture inside OPEC would inject fresh uncertainty into the sour-crude market just as the group tries to manage the return of shut-in supply.
