The UAE’s departure will test OPEC

The decision shifts the balance within OPEC and could have an outsized impact on smaller producers. The UAE’s departure from OPEC reflects its growing confidence as a low-cost producer with expanding production capacity. On April 28, 2026, the United Arab Emirates announced it planned to withdraw from the Organization of the Petroleum Exporting Countries (OPEC), effective May 1, 2026. According to the UAE Ministry of Energy and Infrastructure, the decision followed a comprehensive review of the country’s production policy and capacity outlook. The step was meant to reflect the country’s “long-term strategic and economic vision” and “evolving energy profile,” including accelerated investment in domestic energy production. The announcement initially surprised markets. The UAE had been a member of OPEC since the Emirate of Abu Dhabi joined in 1967 (before the formation of the UAE federation in 1971). While other countries have left OPEC before, they were either facing declining production, like Indonesia, or were significantly smaller producers than the UAE, such as Ecuador and Angola. The UAE’s importance as a producer rests not only on its production volumes, but also on the credibility of its expansion plans and its ability to raise output when needed. Although several producers have announced ambitious capacity targets, few have matched the UAE’s ability to turn such plans into actual production capacity. While the announcement generated considerable media attention, its effect on oil markets proved relatively limited. Coming amid the war between Iran and the United States, the news was quickly overshadowed by more immediate geopolitical and supply concerns. Beyond a short-lived media frenzy, market attention remained firmly focused on the conflict. Major strategic decisions of this nature are rarely made suddenly. The UAE’s withdrawal is best understood as the culmination of years of evolving priorities, changing market conditions and shifting geopolitical realities. Officially, the move has been framed in terms of flexibility and changing market dynamics, but the precise meaning of these concepts remains open to interpretation. The global oil market is entering a period of slower demand growth, intensifying competition among producers and growing uncertainty about the long-term trajectory of oil consumption. In these circumstances, low production costs and secure access to markets become increasingly valuable strategic assets. The UAE’s departure reflects how one of the world’s most competitive oil producers is positioning itself for a changing market environment. UAE ambitions and OPEC constraints The UAE’s decision to leave OPEC was the culmination of a strategic shift that had been developing for years. At its core was a growing mismatch between the country’s expanding production ambitions and a production management system increasingly focused on restraining output. The roots of this divergence go back to 2018, when ADNOC, the Emirates’ flagship state-owned energy company, announced a major investment program aimed at increasing the UAE’s oil production capacity to 4 million barrels per day by the end of 2020, while setting a longer-term target of 5 million barrels per day by 2030. In 2022, ADNOC brought that 5 million-barrel target forward to 2027. As production capacity expanded, however, the gap between what the UAE could produce and the output allowed under OPEC+ widened. This was largely because the country’s agreed production baseline – the reference level used to determine production quotas – did not keep pace with its rapidly growing capacity. In January 2026, the UAE was the third-largest producer among the 12 members of OPEC. Within the broader OPEC+ alliance (22 countries), the UAE was the fourth-largest producer, after Saudi Arabia, Russia and Iraq. The UAE accounted for about 8% of total OPEC+ production. After the UAE’s withdrawal on May 1, 2026, OPEC comprises 11 members: Algeria, the Republic of the Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia and Venezuela. Together with 10 non-OPEC producers – Azerbaijan, Bahrain, Brunei, Kazakhstan, Malaysia, Mexico, Oman, Russia, Sudan and South Sudan – the group formed the broader OPEC+ alliance operating under the Declaration of Cooperation (DoC). The UAE accounts for more than 4% of global oil production and holds nearly 7% of global proven oil reserves. The issue surfaced publicly in 2021 when the UAE challenged the production baseline used to calculate its OPEC+ quota, arguing that it no longer reflected the country’s expanded production capacity. The ensuing compromise increased the UAE’s baseline from 3.168 million barrels per day to 3.5 million barrels per day from May 2022, while a further adjustment in 2024 raised it to 3.519 million from 2025. Yet even as OPEC+ accommodated some of Abu Dhabi’s demands, the gap between the UAE’s permitted production levels and its rapidly growing capacity continued to widen. Much of this growth took place during a period of subdued oil prices and significant OPEC+ production cuts aimed at keeping those prices from falling further. At the time, there was limited scope to accommodate higher production baselines. By the time it withdrew, the UAE was approaching its objective of 5 million barrels per day of production capacity, while its reference production level remained just above 3.5 million barrels per day. In other words, roughly 1.5 million barrels per day of potential production capacity remained outside the quota framework. Nearly a third of the country’s productive capacity was effectively constrained by OPEC+ agreements – the largest such gap among OPEC members. This imbalance mattered because the opportunity cost of compliance was rising faster for the UAE than for most of its peers. While all OPEC members accept production limits in pursuit of collective market objectives, the burden is not distributed equally. Countries with stagnant or declining capacity face a very different calculation from those investing heavily in new production. For the UAE, which was investing heavily into expanding its production, this restraint was becoming progressively more costly. Shifting dynamics within OPEC The UAE’s departure alters the balance within OPEC. Following its exit, Saudi Arabia’s share of the organization’s production rises to around 40 percent. Saudi Arabia and Iraq together account for nearly 60 percent of total output. On paper, a smaller and more concentrated group may appear easier to manage. Yet concentration does not necessarily translate into cohesion. If anything, the UAE’s departure highlights a challenge that may become more pronounced in the years ahead: how to reconcile the differing ambitions and circumstances of member countries. Iraq is a particularly important case. As OPEC’s second-largest producer, it has repeatedly struggled to comply with production targets and remains heavily dependent on oil revenues. The country’s oil sector is also shaped by the significant role of international oil companies, creating a different set of incentives from those found in more centrally controlled systems. Many Iraqi policymakers and industry participants argue that years of wars, sanctions and instability have cost the country market share, strengthening the case for higher production whenever circumstances permit. Other members face their own pressures. Iran possesses substantial untapped production potential and could emerge as a stronger counterweight within the organization, should sanctions be eased and production recover. Venezuela continues to hold some of the world’s largest proven oil reserves, while Libya has announced ambitious plans to increase production from current levels. Although each country faces distinct challenges, they share a common objective: expanding output and monetizing resources. The organization’s future will depend on its ability to maintain unity among producers whose growth ambitions, fiscal needs and political circumstances increasingly diverge. Competition and cooperation among oil producers The significance of the UAE’s departure extends beyond OPEC itself. It points to the increasingly competitive environment facing oil producers. Even if global oil demand continues to grow for years, supply capacity may expand faster than demand. New production from both OPEC and non-OPEC producers, combined with substantial untapped potential in countries such as Venezuela, Libya and Iran – three OPEC members currently exempt from any quota restrictions – suggests that producers may increasingly have to focus on securing and defending market share rather than finding resources. Countries with low production costs, significant reserves and the ability to expand output are likely to be best positioned. This helps explain why several major producers, particularly in the Gulf, have continued to invest in production capacity despite growing uncertainty over the longer-term outlook for oil demand. The objective is not only to produce more, but to preserve a competitive position in a market that may become more and more crowded. Greater competition, however, does not necessarily imply the end of cooperation. While producers may increasingly compete for market share, they will continue to share important common interests. These include maintaining access to markets, ensuring the security of energy flows and preserving revenues on which many of their economies remain heavily dependent. The recent Strait of Hormuz standoff offers a useful illustration. If regional producers had been better connected through pipelines, storage facilities and export infrastructure, much of the disruption could have been mitigated. Future cooperation will likely extend beyond production management to encompass infrastructure development, alternative export routes and broader supply-chain resilience. The objective would not necessarily be to limit competition, but to strengthen the ability of producers to deliver energy reliably to international markets. For some producers, participation in a broader group may remain advantageous despite growing competitive pressures. Countries such as Iraq, whose economies remain heavily dependent on oil revenues, may ultimately derive greater benefit from helping shape decisions within an influential producer group than from acting independently in a more competitive environment marked by weaker prices and greater uncertainty. Flexibility for the UAE after OPEC In announcing its departure, the UAE emphasized both flexibility and its commitment to remaining a responsible producer. However, it did not specify what either concept means in practice. Historically, flexibility has been associated with spare production capacity that can be brought to market during disruptions and ease pressure on prices, or withheld to reduce a supply glut and put upward pressure on prices. However, maintaining spare capacity is costly. Furthermore, while consumers and the wider market benefit from greater supply security, the producer maintaining that capacity bears the cost through forgone production and revenue. In effect, it can amount to subsidizing both competing producers and consumers. This burden is easier to justify within a collective framework such as OPEC, where the costs and benefits of market management are shared. Once operating independently, the rationale becomes less obvious. The UAE’s departure therefore raises an important question: in this context, does flexibility mean maintaining spare capacity, or simply preserving the freedom to decide independently when and how production capacity is deployed?
