Fifty-eight years and one pipeline

On May 1, 2026, the United Arab Emirates ended its fifty-eight-year membership in the Organization of the Petroleum Exporting Countries. The departure of OPEC's third-largest producer — a country pumping 3.5 million barrels a day, with capacity to reach five million by next year — was not a tantrum or a bluff. It was a decision years in the making, accelerated by a war, a broken alliance, and a piece of infrastructure that runs 400 kilometers through the desert from the oil fields of Abu Dhabi to the port of Fujairah on the Gulf of Oman. The Financial Times treats it as the most significant defection the cartel has faced since its founding in 1960. The article's title asks the question plainly. The answer turns out to be three stories layered on top of each other.

A country that could produce five but was told to pump three

The commercial case for leaving OPEC was straightforward: Abu Dhabi had invested $150 billion to build capacity it was not permitted to use.

OPEC's founding mandate in 1960 was to coordinate petroleum policy — which in practice meant fixing oil prices by managing supply. When the cartel had forty percent of global production, sixty percent of traded oil, and eighty percent of proven reserves, this worked. By 2026, those numbers had fallen to thirty-three, forty-six, and seventy-three percent respectively. The instrument was the same — production quotas, allocated by member state — but the world had changed. The United States had become the world's largest oil producer. Norway, Brazil, Guyana, and Canada had added millions of barrels to global supply. OPEC's ability to move prices depended on members accepting cuts, and the UAE had been accepting cuts it could no longer afford.

The gap between what ADNOC could produce and what OPEC allowed it to produce had become the defining frustration. At 4.85 million barrels per day of capacity and a quota hovering around 3.2 million, the UAE was sitting on roughly 1.6 million barrels per day of stranded value — every day, indefinitely, for as long as it remained a member. The FT frames this as the commercial core of the exit: Abu Dhabi had spent the money, built the wells, and now wanted to sell the oil.

Other members had left before — Indonesia in 2016, Qatar in 2019, Ecuador in 2020, Angola in 2024 — but none carried the UAE's combination of volume, spare capacity, and geopolitical weight. The UAE was, by several analysts' accounts, OPEC's true swing producer: the only member besides Saudi Arabia with significant spare capacity, and arguably the only one whose spare capacity was real rather than aspirational. Its departure removes from the cartel the very flexibility that made coordinated supply management credible.

When Abu Dhabi and Riyadh stopped talking

The commercial case was necessary but not sufficient. What made the timing possible was the collapse of the UAE's most important regional relationship.

The FT and the Council on Foreign Relations both trace the same sequence. In late 2025, the UAE backed a power grab by the Southern Transitional Council, a Yemeni separatist group, at the expense of Saudi-aligned partners. Saudi Arabia responded with airstrikes on Emirati allies and military equipment at the Port of Mukalla. Then came Israel's recognition of Somaliland, which the Saudis perceived as destabilizing and suspected Emirati complicity in arranging. What followed was a two-month war of words — conducted largely over social media and through competing lobbying campaigns in Washington — as each side argued that the other was responsible for the breakdown.

The close coordination between Abu Dhabi and Riyadh that American policymakers had come to treat as a regional constant was, as the CFR's Steven Cook puts it, "not the norm." Smaller Gulf states have historically resisted Saudi efforts at regional dominance. The unusually tight alignment of the late 2010s and early 2020s — built around the Abraham Accords, shared hostility toward Iran, and coordinated oil policy — was the exception. By the time the war with Iran began in late February 2026, the exception was over.

The Iran war accelerated the split without causing it. When Iranian drones and missiles struck both countries in the opening days of Operation Epic Fury, Crown Prince Mohammed bin Salman and UAE President Sheikh Mohamed bin Zayed expressed solidarity. It lasted weeks. Saudi Arabia then joined Pakistan, Egypt, and Turkey in seeking a diplomatic off-ramp. The UAE, having absorbed a disproportionate share of Iranian fire — roughly 2,820 of the 6,000 drones and missiles launched at Gulf states during the forty-one days of active hostilities — wanted guarantees that Iran could not threaten its security again. It concluded that Riyadh was willing to settle for less. The trust that had briefly reconsolidated under fire evaporated.

The FT's argument, which the CFR echoes, is that the Emiratis had been studying the option of leaving OPEC since Qatar's departure in 2019. What the Saudi fracture provided was not the motive but the moment. With the bilateral relationship already in ruins, the political cost of defying Riyadh on production policy — which is to say, on the thing Saudi Arabia cares about most — dropped to near zero.

Four hundred kilometers to Fujairah

The Habshan-Fujairah pipeline does not just bypass OPEC. It bypasses the Strait of Hormuz.

There is a reason the UAE could leave OPEC in the middle of a war that has closed the most important oil chokepoint on earth, and that reason is a pipeline completed in 2012 that almost nobody was paying attention to at the time. The Abu Dhabi Crude Oil Pipeline — known as ADCOP, or the Habshan-Fujairah pipeline — runs 400 kilometers from the onshore oil fields at Habshan in southwestern Abu Dhabi to the port of Fujairah on the Gulf of Oman. It was built by China Petroleum Engineering, ordered by the International Petroleum Investment Company, and designed for precisely the scenario now unfolding: a world in which the Strait of Hormuz is not available.

The Habshan-Fujairah pipeline, also known as ADCOP, is a 400-kilometer line completed in 2012 that carries U.A.E. crude from the Habshan field in the western desert overland to the port of Fujairah, on the Gulf of Oman. It exits the country east of the Strait of Hormuz, bypassing the strait entirely. Until ADCOP, every barrel of U.A.E. oil had to transit Hormuz; today the pipeline can move roughly 1.8 million barrels a day, leaving Riyadh and Tehran without the leverage they once had.

The pipeline's nameplate capacity is 1.5 million barrels per day, with reported current capacity close to 1.8 million. Before the war, the UAE was already routing roughly 1.1 million barrels through Fujairah, leaving headroom for up to 700,000 additional barrels if the strait were disrupted. The strait has now been effectively closed for over nine weeks. Fujairah has become not just the UAE's primary export terminal but one of the most strategically important bunkering hubs in the world — alongside Singapore and Rotterdam — handling crude storage, ship refueling, and exports to India and East Asia.

The pipeline also explains the war's geography. Iran struck the Fujairah terminal directly, along with Saudi Arabia's East-West pipeline to Yanbu. The message was clear: Tehran would not allow Gulf states to route around the strait without cost. But the pipeline is underground, dispersed, and harder to destroy than a refinery or a port. ADNOC announced on May 4 — three days after the exit — that it was accelerating $55 billion in project awards over the next two years, including expanded pipeline capacity and new export infrastructure at Fujairah.

Why Trump called it great

The UAE's exit serves American interests on at least four fronts — and Washington did not even have to ask for it.

Donald Trump's reaction was blunt. "I think it's great," he said, "and ultimately a good thing for getting the price of gas down." The White House had several reasons to be pleased beyond gasoline prices. The UAE was always the foundation stone of Trump's Middle East policy, built around the Abraham Accords — the normalization deals between Arab states and Israel. The Emirates signed the first major deal in September 2020, and despite widespread reports, never fully severed diplomatic ties with Israel after October 7, 2023. An OPEC-free UAE, willing to pump more, aligned more closely with Washington, and operating a Hormuz bypass pipeline, was precisely the kind of partner the administration wanted.

There was also the India angle. The UAE enjoys an unusually close oil relationship with India — a country chronically short of domestic supply and essential to Washington's strategy of using New Delhi as a counterbalance to Beijing in the Indo-Pacific. More UAE oil flowing freely to India, outside OPEC constraints, deepens that dependency in ways Washington finds useful.

And then there is the OPEC+ dimension. Russia joined the OPEC structure in late 2016, creating the extended cartel known as OPEC+, which Washington had always viewed with suspicion. The UAE's departure weakens not just OPEC but the Saudi-Russian axis that held OPEC+ together. With the UAE gone and Venezuela possibly following — the Maduro government was removed on January 3, 2026, and the new administration has already signaled openness to U.S. oil companies — Moscow's ability to use oil production coordination as a geopolitical instrument is diminishing rapidly.

Eleven members and a question

OPEC is not dead. But the cartel that coordinated the 1973 oil embargo now holds a third of global production and has lost its swing producer.

The remaining eleven members — Algeria, the Republic of the Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, and Venezuela — still account for a third of global crude output and nearly three-quarters of proven reserves. These are not trivial numbers. But the cartel's ability to manage prices depends on its ability to cut and hold. The UAE's departure removes the only member besides Saudi Arabia with significant, credible spare capacity. If Saudi Arabia's own spare capacity is as questionable as some analysts suggest, OPEC's pricing power now rests on discipline alone — and discipline, among eleven countries with divergent fiscal pressures, is the thing cartels are worst at.

The FT raises but does not resolve the succession question. Could other members follow? Qatar's exit in 2019 was geopolitically motivated — a response to the Saudi-led blockade — and set a precedent but did not start a cascade. The UAE's exit is different: it is being framed, by Abu Dhabi and by the markets, as economically rational. If the UAE can demonstrate that leaving OPEC produces higher revenues, better investment returns, and greater strategic autonomy, the argument for staying in becomes harder to make. Iraq, with its chronic overproduction problems, and Nigeria, with its collapsing output, are the most frequently mentioned candidates. Neither is likely to move soon. But the precedent is set.

Three stories, then, stacked inside one exit. The quota trap: a country that built the capacity and was told it could not use it. The fracture: a bilateral relationship broken by Yemen, Somaliland, and divergent readings of how a war should end. The pipeline: a piece of infrastructure, ordered when Hormuz was a theoretical risk, that became a strategic asset when Hormuz became an actual one.

The FT treats the commercial logic as primary and the geopolitics as enabling. The CFR treats the geopolitics as primary and the commercial logic as necessary but not sufficient. Both are probably right. What neither quite says, but what the chronology makes visible, is that the pipeline is the thing that connects the two stories. Without it, the UAE could leave OPEC and still be stranded. With it, the UAE can leave OPEC, keep exporting through a war, and use the extra capacity to become exactly the kind of partner — flexible, pro-Western, infrastructure-independent — that Washington needs in a region it is trying to reorganize.

The reader who has followed this collection from the Dalio piece onward will recognize the pattern. Empires strain. Institutions built for one era — Suez, Bretton Woods, OPEC — lose their grip in the next. The question is never whether the institution survives. It is who moves first, and what they have built to land on.
