OPEC+ Delays 2027 Oil Capacity Review to Mid-November Amid Iran Conflict

OPEC+ has postponed the completion of its sustainable oil production capacity review from late September to mid-November 2026. The assessment, which establishes the baseline for individual member output quotas for 2027, was delayed after regional conflict involving the U.S., Israel, and Iran interrupted Middle East capacity expansion projects. The disruptions have prevented several member states from submitting necessary operational data. The postponement adds supply uncertainty to an alliance already facing strain, following the United Arab Emirates' departure in May and continued demands from Iraq for higher output allocations.
