OPEC+ wraps up output restoration with September hike, looks to Q4 surplus

OPEC+ has approved a 188,000 bpd quota increase for September, completing its planned output restoration. The move is largely symbolic as war-related disruptions persist, and the group now faces managing a potential Q4 surplus and 2027 quota negotiations.

OPEC+ has given its approval to raise production quotas by roughly 188,000 barrels per day from September, a step that brings the group's planned output restoration to a close. The decision, confirmed by the core members of the alliance — Saudi Arabia, Russia, Iraq, Kuwait, Algeria, Kazakhstan and Oman — marks the final stage in unwinding a 1.65-million bpd supply cut that was originally agreed in 2023. Notably, the United Arab Emirates, which was part of the group when that cut was first negotiated, left OPEC in May 2026 and did not take part in the latest decision.

The September increase completes the phased rollback of that voluntary cut, but analysts suggest the move is largely symbolic. Over most of 2026, successive monthly hikes from OPEC+ have remained mostly on paper due to export disruptions from the Gulf, Russia and Kazakhstan, which have been affected by the wars involving Iran and Ukraine. These conflicts have hampered actual supply flows, limiting the real-world impact of the quota increases. In its statement, OPEC+ made no mention of any output decision for the fourth quarter, leaving the market without clear guidance on near-term supply.

Jorge Leon, an analyst at Rystad, commented: "Opec+ has finished unwinding its voluntary cuts. The next challenge is managing the surplus that could emerge as export flows normalise." He added: "Having completed the restoration campaign, Opec+ has little incentive to rush into further supply changes. Our base case is a fourth-quarter pause while the group prepares for the 2027 quota negotiations." Indeed, OPEC+ is currently reviewing members' oil production capacity to set new output baselines for 2027, a process that has already sparked tensions. Iraq, for example, is pushing for a higher individual quota to reflect its increased capacity.

The joint ministerial monitoring committee, which met on Sunday, reiterated its concern about attacks on energy assets during the US-Israeli war on Iran, noting that repairs are expensive and time-consuming and have an impact on supply. This adds to the uncertainty surrounding the market. Even after the September hike, OPEC+ still has another layer of output cuts of roughly 2 million bpd that dates back to 2022, which is due to remain in place until the end of 2026. The group, which comprises 21 members including Russia and other allies, has signaled that quotas are likely to remain steady through year-end amid the Middle East supply uncertainty.

The next meeting of the seven core members is scheduled for September 6, 2026, and market observers will be watching for any signs of a policy shift as the group navigates the delicate balance between supporting prices and accommodating geopolitical disruptions.
