VIENNA, July 21 — The 23-nation OPEC+ alliance holds a spare production capacity of roughly 4 to 5 million barrels per day, a buffer concentrated in Saudi Arabia and the United Arab Emirates, according to the group’s own data and public statements by its leading ministers. That cushion has not been tapped, even as war between Iran and Israel continues to roil the Middle East.
The record shows OPEC+ has not called an emergency meeting or imposed additional cuts since the conflict began. The timeline of cuts OPEC+ first announced a collective cut of 2 million barrels per day in October 2022, a reduction that was extended through all of 2023. Then in April 2023, nine member countries — Saudi Arabia, Russia, Iraq, the UAE, Kuwait, Kazakhstan, Algeria, Oman, and Gabon — announced additional voluntary cuts totaling 1.66 million barrels per day.
In June 2024, the group agreed to extend most of those production limits into 2025. Saudi Energy Minister Prince Abdulaziz bin Salman signaled at the time that the kingdom was ready to increase output if market conditions warranted it, according to the minister’s public remarks. Demand versus supply The cartel’s restraint is partly a response to changing demand. Global oil demand growth slowed to about 1.2 million barrels per day in 2024, down from 2.3 million barrels per day in 2023, according to widely cited industry estimates.
That drop reduces the urgency for additional cuts to prop up prices. At the same time, non-OPEC producers are steadily adding supply.
U.S. shale output, Brazilian offshore fields, and Guyana’s growing production have all chipped away at the market share OPEC+ once commanded. The combination of slower demand growth and rising non-OPEC supply has given the group less room to maneuver. Russia remains a core member of the alliance, with a pre-sanctions production capacity of about 10.5 million barrels per day.
Saudi Arabia, the de facto leader, has a capacity of 10.9 million barrels per day. Those two producers, along with the UAE, hold the bulk of the spare capacity that could be called upon in a crisis. What to watch next The key question for the second half of 2026 is whether the 4 to 5 million barrels per day of spare capacity will remain idle — or be deployed if geopolitical disruptions tighten the market.
Prince Abdulaziz’s earlier signals suggest Saudi Arabia is willing to act, but only if it sees a genuine need, not a speculative price spike. For now, OPEC+ appears content to sit on its hands, letting the slow growth in demand and the steady inflow of non-OPEC barrels do the work of balancing the market.
The Iran-Israel war, while severe, has not yet triggered any supply emergency that would force the group’s hand. That could change with a single pipeline attack or shipping disruption in the Strait of Hormuz — but as of July 21, no such event has occurred.
