OPEC+ Adopts Capacity-Based Quota Mechanism

Member states of the OPEC+ alliance approved a new framework to assess each country’s maximum sustainable oil production capacity, with the outcome to determine output baselines from 2027. The decision was announced by Saudi Energy Minister Prince Abdulaziz bin Salman, who described the methodology as fair and transparent. The evaluation process covering most members will run from January to September 2026, laying the foundation for quota allocations.

The mechanism was mandated by the alliance earlier this year following its 39th Ministerial Meeting, when the secretariat was tasked to craft a robust method to estimate maximum sustainable capacity and report back. That mandate has now been formalised, ending prolonged internal debate over how to reflect capacity expansion or declines across diverse producers.

At the same time, OPEC+ decided to hold its current group-wide oil output quotas for 2026 unchanged, including a pause in planned output increases by eight core members such as Saudi Arabia, Russia, UAE and Kuwait. This decision preserves existing cuts equivalent to roughly 3.24 million barrels per day, or about 3 percent of global demand.

Officials said the new capacity assessment will cover 19 of the 22 OPEC+ members. Countries under Western sanctions — notably Russia, Iran and Venezuela — will have their quotas determined using alternate methods, potentially based on historical output averages rather than fresh capacity audits.

Some members that have significantly expanded production infrastructure, including UAE, are expected to benefit from a higher baseline once the evaluation is complete, while producers facing declining output capacity, particularly several African states, could see their quotas reshaped downward. The move aims to reward investment and reflect real production capabilities rather than historical allocations.

By anchoring future quotas to technical assessments of maximum sustainable capacity rather than fixed historic baselines, OPEC+ seeks to reduce internal tensions and better adapt production rights to evolving capacity dynamics. Prince Abdulaziz described the outcome as “the most detailed, most technical, transparent approach” to managing oil markets going forward.

The group’s decision has market watchers cautiously optimistic. By signalling that quotas will reflect actual capacity, OPEC+ may restore some confidence among investors in oil-producing nations and reduce the risk of abrupt quota disputes or member exits. The approach could also stabilise supply expectations at a time when recovery in global demand remains uncertain and as unregulated producers weigh increasing output.
