UAE Exits OPEC as Cartel Faces Largest Fracture Since 1973
Abu Dhabi's withdrawal amid Strait of Hormuz closure and Ukrainian strikes on Russian refineries leaves OPEC structurally weakened as oil hits $111 per barrel.
The United Arab Emirates will leave OPEC effective May 1, ending a 46-year membership in the oil cartel’s most significant fracture since 1973, as the organisation faces a 27% production collapse and historic supply shocks on multiple fronts.
The withdrawal, announced April 28 by Energy Minister Suhail al-Mazrouei, positions the UAE to boost output from 3.4 million barrels per day to 5 million by 2027—directly competing with Iraq and undermining Saudi Arabia’s role as market stabiliser. The timing exploits the Strait of Hormuz closure, which has reduced tanker traffic 95% and limited immediate competitive pressure, according to CNN.
Strategic Realignment, Not Emergency Exit
Abu Dhabi’s decision reflects decade-long frustration with production caps that prevented utilization of 4.85 million barrel per day capacity built through $150 billion in ADNOC investments, per The National. The UAE has chafed under quota discipline while watching Saudi Arabia maintain swing producer status and regional influence.
The withdrawal signals a broader geopolitical pivot following the Abraham Accords, as the UAE deepens alignment with Israel and the United States while diverging from Riyadh on Yemen, Sudan, and Red Sea security. “This is a policy decision. It has been done after a careful look at current and future policies related to level of production,” al-Mazrouei told Reuters.
“Outside the group, the UAE would have both the incentive and the ability to increase production, raising broader questions about the sustainability of Saudi Arabia’s role as the market’s central stabiliser.”

Cartel Collapse Meets Supply Shock
OPEC’s production fell to 20.79 million barrels per day in March from approximately 28 million pre-war—a 7.88 million barrel daily supply shock exceeding both the 1973 oil embargo and 1991 Gulf War, according to Al Jazeera. The cartel’s share of global output dropped to 44% in March from 48% in February.
The Strait of Hormuz, carrying 20% of global oil and 35% of seaborne crude trade, now handles just 6-7 ships daily versus 125-140 before the Iran war. War-risk insurance premiums surged to 5%-10% of hull value from 0.15%-0.25% pre-conflict, effectively pricing most commercial traffic out of the waterway, per Euronews.
Second Theater: Ukraine Hammers Russian Exports
Ukrainian drone strikes destroyed $2.3 billion in Russian oil revenue during March alone, targeting refineries and export terminals from Tuapse to Yaroslavl. The April 20 attack on Tuapse destroyed 24 storage tanks and marked the refinery’s third hit this month, CBC News reported. The International Energy Agency cut Russia’s supply forecast by 120,000 barrels per day for the remainder of 2026.
The parallel disruptions—OPEC’s structural fracture and Ukraine’s systematic degradation of Russian export infrastructure—arrive precisely when the cartel’s spare capacity discipline has evaporated. Russia’s March oil revenue paradoxically jumped to $19 billion from $9.75 billion in February despite the strikes, reflecting higher prices overwhelming volume losses.
OPEC’s last major membership change came in 1973 when Ecuador joined during the oil embargo. Qatar departed in 2019 over minor policy differences, but the UAE withdrawal represents the first exit by a Gulf producer and OPEC’s third-largest member. The cartel now controls 44% of global supply, down from 55% in 2016.
Price Volatility Ahead
Brent crude reached $112.70 intraday on April 28 before settling at $111.26, while WTI traded at $99.93. The World Bank forecasts energy prices surging 24% in 2026, with Brent potentially averaging $115 per barrel if Hormuz disruptions persist through mid-year.
US gasoline hit $4.18 per gallon on April 28—the highest this year—as refiners absorbed both the OPEC supply shock and tighter crude differentials. The UAE’s planned production increase offers potential relief, but only after Hormuz reopens and new capacity comes online over 12-18 months.
- UAE production ramp to 5M bbl/day by 2027 directly competes with Iraq’s 4.3M bbl/day output
- OPEC+ coordination weakens as non-OPEC producers (US shale, Guyana, Brazil) capture market share
- Saudi Arabia loses swing producer leverage with UAE no longer bound by quota discipline
- Insurance market remains key bottleneck—Hormuz premium structure determines pace of supply normalisation
What to Watch
The immediate focus shifts to Saudi Arabia’s response and whether other Gulf producers follow the UAE’s exit. OPEC+ meetings scheduled for June face new pressure as Russia manages refinery damage and the cartel’s spare capacity remains offline behind Hormuz. Qatar and Kuwait, both with expansion plans constrained by OPEC quotas, represent the next fracture points.
Markets will track the UAE’s actual production increases versus stated targets—ADNOC’s 4.85 million barrel capacity allows rapid ramp-up once export routes stabilise. The timing of Hormuz reopening determines whether the UAE’s additional barrels alleviate or exacerbate price volatility, with insurance underwriters holding effective veto power over tanker traffic resumption.
Geopolitically, the withdrawal cements the UAE’s strategic tilt toward Israel and the US, with energy policy now fully decoupled from Saudi coordination. For OPEC, the loss of its third-largest producer at the peak of a supply crisis marks the end of cartel cohesion that survived five decades of oil shocks, embargoes, and price wars.
