OPEC+ Delays 2027 Oil Capacity Review Amid Iran Conflict
By Drooid · · How we work
Core Event: Review Postponed to Mid-November
On Oct 2, OPEC+ announced that the assessment of members’ maximum sustainable production capacity (MSC) – the basis for setting 2027 oil-output quotas – will not be completed by the end of September 2026 as originally scheduled. Sources close to the process say the review is now expected to finish by mid-November, allowing the findings to be considered at the group-wide meeting slated for late November.
Background & Context: War Disrupts Expansion Projects
The delay follows the outbreak of the US-Israeli war on Iran, which has halted several capacity-expansion projects across the Middle East. The conflict has also constrained crude flows through the Strait of Hormuz, further complicating estimates of future output potential for OPEC+ members.
Official Statements & Responses
- Russian Deputy Prime Minister Alexander Novak, cited by the state news agency TASS, indicated that OPEC+ countries continue to assess their maximum production capacities despite the disruptions.
- OPEC+ did not provide an immediate comment when approached for comment on the postponement.
Data & Statistics: Timeline and Scope of the Review
- Late 2025: OPEC+ ordered the MSC review for all members.
- End Sept 2026: Original deadline for the review’s completion.
- Mid-Nov 2026 (projected): New target date for the assessment’s submission, according to the consulting firm DeGolyer & MacNaughton, which is preparing the capacity estimates for all OPEC+ members except Russia, Iran and Venezuela because of U.S. sanctions.
- Oct 4: The next OPEC+ meeting is scheduled, with an existing layer of production cuts remaining in place through the end of 2026.
Why It Matters: Potential Influence on 2027 Quotas
The MSC assessment directly informs negotiations over individual members’ output quotas. Countries whose assessed capacity is lower may face pressure to accept smaller allocations, while those that have successfully expanded capacity could argue for higher quotas. The United Arab Emirates left the alliance in May after seeking a larger quota, and Iraq has reportedly requested a higher allocation and considered exiting OPEC, underscoring how the delayed review could reshape the balance of production rights within the group.
