What does the UAE walking out of OPEC mean for Russia’s war on Ukraine?

The United Arab Emirates leaves OPEC on 1 May. For Ukraine, the impact runs through one number: Russia’s oil revenue, which still pays for the war. Russian Finance Minister Anton Siluanov publicly admitted on Wednesday that the exit will push global prices down. Less oil money. Less war money.

The scale is real. UAE could add 1.6 million barrels per day to global supply—1.5% of world oil—once Hormuz shipping resumes. Markets price the news before barrels arrive: even announcement effects move oil prices and downstream macroeconomic conditions, analysis in The Conversation notes, citing precedents from the 1979 oil crisis and the 1985–86 collapse.

But the squeeze is incremental. Russian revenues fell sharply in 2025. Then the Iran war intervened: the Strait of Hormuz closed in February, prices spiked, Russian crude touched around $100 a barrel, and Russia’s daily oil revenue rose by up to $150 million.

Ukrainian strikes on export terminals—Primorsk, Ust-Luga, Novorossiysk—clawed some of that back. UAE’s exit threatens what remains of the windfall the moment shipping resumes.

“No, they did not warn us”

Kremlin spokesman Dmitry Peskov confirmed on Wednesday that the UAE did not warn Moscow before announcing its exit. Russia stays in OPEC+, Peskov said. “No, they did not warn us. This is a sovereign decision.”

With OPEC+ collapsing, Russia loses its last lever on the global oil market, wrote Ihor Semyvolos, director of the Center for Middle Eastern Studies at Ukraine’s National Academy of Sciences, on 30 April in Ukrainian outlet Glavcom. Russia and Saudi Arabia together held a 4-million-barrel-per-day reserve buffer—the spare capacity that let the cartel move prices. UAE’s exit splits that buffer.

A deep regional rupture

The split is structural, not tactical. UAE’s exit reflects what energy consultant Anas Abdoun wrote in Al Jazeera was a “deep regional rupture between Riyadh and Abu Dhabi”—the two see the future of Gulf order differently.

Saudi Arabia wants OPEC production capped to defend high prices over the long run. The UAE wants to maximize output before global oil demand peaks, energy strategist Kingsmill Bond at think tank Ember Future told Al Jazeera. OPEC discipline, in that view, is a constraint to escape from.

The war hardened the divergence. Iran’s strikes cut 44% off Emirati output at the peak—and Iran is itself an OPEC member. The cartel where one member bombs another’s production is a pretense the UAE no longer has reason to maintain. Kazakhstan already ignores quotas, Semyvolos notes; Nigeria and Venezuela are watching the door.

Why doesn’t it break the Kremlin

Russia’s 2026 budget will be executed largely as adopted by the State Duma last year, Russian economist Vladislav Inozemtsev of the Center for Analysis and Strategies told Euromaidan Press in early April. “A collapse is not imminent.” If pressure on the Kremlin’s budget eases, Inozemtsev added, the savings will shift to military expenditures.

His sharper point for Ukraine: strikes on Russian export terminals damage the budget far more than strikes on refineries. Hit a refinery, and Russia exports the crude. Hit an export terminal, and the budget bleeds.

One more pressure point

UAE’s departure from OPEC is yet another pressure point on Russia’s war funding. It will not end the war or force Putin to the table. But the architecture is fracturing. US President Donald Trump has spent the past year pressing OPEC for prices.

Saudi Arabia is silent. Every barrel of UAE crude that reaches the market without a quota—once Hormuz reopens—pulls against the price floor that funds Russian missiles.

In the background, Ukrainian President Volodymyr Zelenskyy announced this week that Drone Deals are underway with countries across the Middle East and the Gulf. Russia is trying to block them.

For now, the Strait of Hormuz remains closed. Until shipping resumes, the UAE’s first quota-free barrel cannot reach the market.
