The United Arab Emirates's exit from the Organization of the Petroleum Exporting Countries took effect on May 1, 2026, ending a membership that had lasted more than five decades. The departure followed years of public complaints from the UAE about OPEC quotas that limit oil production for all member countries.

The UAE had invested in boosting oil production over the past few years but was not able to market the volumes it wanted. In April 2026, the UAE also requested a currency swap line from the United States.

"The exit was a surprise in timing (at least to me), but in some ways has been brewing for some time," said Rachel Ziemba, an adjunct senior fellow at the Center for a New American Security. "It prompts the question whether there will be more competition than cooperation in the region and what the governance of the energy markets will look like."

Adnan Mazarei, a nonresident senior fellow at the Peterson Institute for International Economics, said the swap line request carried diplomatic weight. "The US would welcome a weakening of the OPEC and OPEC+. They do have some ability to set prices, and a decline in that power will be welcomed by the US," he said.

The exit came as the Strait of Hormuz, through which 20 percent of the world's oil and gas transits, remained blocked following an attack by the U.S. and Israel on Iran. Iran retaliated by closing the strait and attacking energy infrastructure and U.S. bases in the region.

He also addressed the future of the cartel and regional bloc. "There is a chance of other countries defecting. But if I had to bet, I'd say OPEC will survive, but in a weaker shape and effectiveness," Mazarei said. "The question is, will the GCC survive?"
