On April 28, the United Arab Emirates announced that it would end its 59-year membership in the Organization of Petroleum Exporting Countries (OPEC)—pointedly coming on the same day that Saudi Arabia’s Crown Prince Mohammed bin Salman was presiding over a Gulf Cooperation Council (GCC) summit that was supposed to lead to greater unity among the countries of the Arabian Peninsula. Despite the shocking news, the markets barely reacted, with oil prices dominated by the war in Iran and the partial closure of the Strait of Hormuz. But the muted response obscures what the decision actually reveals: where the UAE is positioning itself geopolitically, how far the Saudi-Emirati rivalry has evolved, and how a Gulf region under immense external pressure is counterintuitively pulling itself apart.
The Economics
The most obvious reason for the exit is economic, as it frees the UAE from OPEC’s quota system. Abu Dhabi’s national oil company, ADNOC, has spent a decade expanding its production capacity—reaching approximately 4 million barrels per day (bpd) in 2023 and planning to reach 5 million bpd by 2027. Before the current war, the UAE’s output was around 3.4 million bpd, already pressing against its quota ceiling despite a sustainable capacity of between 4.5 and 5 million bpd. At current prices, the quota-induced production constraints impose an annual opportunity cost of $50–70 billion. In previous years, Abu Dhabi had used the threat of exit as a bargaining chip to secure quota increases, including blocking an OPEC+ deal in 2021 and stalling talks for weeks until a compromise was reached. From this perspective, the exit decision was a long time coming and marks the end of that strategy.
The Iran conflict has sharpened the incentive to maximize oil output. Disruptions in Hormuz have cut into export revenues, and while the Habshan-Fujairah pipeline can bypass the strait for 1.5–1.8 million bpd, that still leaves a significant share of production stranded. Added to this are rising costs from air defense and physical and commercial damage. Therefore, what had been a longstanding policy deliberation has become an urgent economic imperative.
Further underlying the Emirati decision is a structural assessment of global energy markets. The UAE’s policymakers have concluded that global oil demand is in a terminal decline. This does not imply a sharp, near-term fall in volumes sold, but it does mean sustained downward pressure on prices as the energy transition advances and the ongoing war heightens the rest of the world’s motivation to diversify away from risk-prone Gulf hydrocarbons. The rational response, from Abu Dhabi’s perspective, is to monetize as much oil as possible before reserves and infrastructure become stranded assets.
The Politics
The geopolitical dimension of the decision points first toward Washington. Trump has long framed OPEC as hostile to American consumers and the global economy, accusing it of “ripping off the rest of the world.” The UAE’s exit—whatever its domestic rationale—is therefore a political win for the U.S. In return, Abu Dhabi appears to be securing financial and strategic assurances, including a proposed dollar swap line from the U.S. Treasury—valuable insurance given the unclear path the Gulf conflict is taking.
More broadly, the exit signals a recalibration toward closer alignment with Washington at a moment when Gulf states are reassessing the reliability of the U.S. security umbrella, feeling abandoned by their security patron during a catastrophic war they had doggedly tried to avoid. The OPEC exit can be read—alongside the decision to stay in the “Abraham Accords”—as part of an Emirati strategy to gain stronger reassurances through deeper alignment with the American-Israeli alliance.
Domestically, the exit also reflects internal power dynamics. The UAE’s oil production is overwhelmingly concentrated in Abu Dhabi, and the Emirati constitution assigns control over natural resources to individual emirates rather than the federation. Under OPEC’s quota system, it was specifically Abu Dhabi’s productive capacity that was constrained. Lifting that constraint is, among other things, an Abu Dhabi power play: it expands the emirate’s fiscal space relative to the other six, and strengthens the federation’s center against its periphery. The emirate that matters most in this calculation is Dubai, which has built its economic model on services, tourism, and finance rather than hydrocarbons. A substantially wealthier Abu Dhabi thus shifts the internal balance of the federation.
Most consequential, however, is the Saudi-UAE relationship. Saudi Arabia is the dominant OPEC member: the largest producer, the largest holder of spare capacity, and the author of most of the production decisions that have frustrated Abu Dhabi since the OPEC+ expansion brought Russia into the fold in 2016. The two countries have collided in other economic and strategic arenas as well. For example, Saudi Arabia has used regulatory pressure to compel multinational corporations to relocate regional headquarters from Dubai to Riyadh, and the two have clashed over their approaches to conflicts in Sudan and Yemen.
Quitting OPEC, therefore, is not just about oil revenue, U.S.-alignment, or domestic power recalibration; it also targets the regional rivalry with Saudi Arabia. Not only does it weaken an institution through which Riyadh exercises global influence, but it also hurts Saudi Arabia’s fiscal bottom line as increased Emirati output pushes down oil prices. The key in this equation is that Saudi Arabia’s break-even oil price is substantially higher than the UAE’s, meaning Riyadh requires higher prices than Abu Dhabi to balance its budget. Finally, Emirati oil revenues also translate into additional defense spending capacity, not all of which may be directed against Iran but also towards the same proxy theatres where the Saudi-Emirati rivalry is most visible.
The Outlook
OPEC will survive the UAE’s departure, but its character may change. The move could encourage other members to follow suit. Analysts have flagged Kazakhstan as the most likely candidate, a persistent overproducer that has long strained against its quota. Nigeria, whose Dangote refinery has shifted its incentives toward domestic processing, and Venezuela, with recovering output and increasingly under American influence, are also identified as flight risks. But the UAE is unusual in its financial depth, spare capacity, and diplomatic sophistication. Few other members are in a comparable position to absorb the costs of leaving. Even still, if the end result is a smaller OPEC with less problematic members and more internal cohesion, Saudi Arabia’s grip could tighten and its influence become more pronounced.
For the GCC, the implications are less economic and more geopolitical. The bloc’s security and prosperity depend on a Gulf that is coherent, stable, and politically aligned. The UAE’s OPEC exit is a public demonstration of deepening antagonism between Abu Dhabi and Riyadh, two states that are supposed to be partners in a common peninsular project. A Saudi-Emirati rivalry expressed through OPEC politics, proxy conflicts, economic zero-sum games, and differential responses to the Iran crisis poses a direct problem for any country whose strategic interests require that rivalry to be managed rather than intensified.
Furthermore, there are growing fears that the OPEC exit is only a prelude to more institutional disruption, including in the Organization of Islamic Cooperation, the Arab League, and the GCC. For neighboring states, options to remedy the situation are limited and the clearest recourse is to hedge their relationships while emphasizing their support for institutions. Ultimately, the UAE’s decision to leave OPEC reinforces a lesson already underscored by previous crises—namely, that common external threats do not necessarily produce internal cohesion. On the contrary, they can accelerate underlying divergences.
