Cartel crack: The UAE is exiting Opec and Opec+, breaking ranks within the oil cartel at a time when regional disruptions are already affecting supply chains and pricing.

A structurally significant split: The UAE has long been one of the bloc’s heavyweights alongside Saudi Arabia, with meaningful spare capacity — the key lever Opec uses to move markets — making its departure structurally different from past defections. “The UAE’s exit is very significant as it’s a top-tier producer with high spare capacity and strong compliance with prior quotas,” Rabobank Energy Strategist Florence Schmit tells EnterpriseAM.

Mechanically, the exit removes 3-4 mn barrels daily of swing capacity and the ability to respond when Hormuz closes or pipelines rupture, Wolfgang Lehmacher, former head of supply chain and transport industries at the World Economic Forum, tells EnterpriseAM.

The decision was unilateral: The UAE didn’t consult other members before pulling the trigger, Energy Minister Suhail Al Mazrouei told Reuters, framing the move as a result of a review of current and future production policies. The UAE’s exit from Opec would mark a decisive shift toward an independent, state-driven oil strategy,” MENA economist Hamzeh Al Gaaodwrites in a note (pdf) shared with EnterpriseAM. This allows the country to leverage its position as a supplier of some of the world’s lowest-cost barrels.

A well-timed exit?

The market already is distorted: “Now, is probably the least damaging time to announce it — oil prices are high, ⁠and there are genuine shortages because of Hormuz closure,” Carnegie’s Sergey Vakulenko told Reuters. He added that even “after Hormuz reopens, there will be elevated demand as countries will be replenishing reserves that were drawn down since February, ⁠so prices will stay high.”

The situation points to what could become a broader “governance coordination break simultaneously,” Lehmacher tells us, even as the near-term market reality suggests limited immediate impact. “The prospect of the UAE pumping more oil is somewhat moot at present given the near-complete cessation in flows through Hormuz,” Capital Economics’ Chief Climate and Commodities Economist David Oxley writes in a note seen by EnterpriseAM. Markets are also still catching up to the disruption itself, with a clear pricing lag: “Crude markets are currently still factoring in the Hormuz closure before they can fully price the UAE leaving Opec,” Schmit adds.

The “immediate” impact of the UAE’s exit is likely to be muted, Mazrouei adds. Still, “the timing of this decision, in the context of the ongoing disruptions, will no doubt leave many perplexed,” global oil markets strategist and former head of research at Onyx group Harry Tchilinguirian tells EnterpriseAM, with the deeper concern centering on system resilience.

Why? It’s breaking out of the quota box

The rupture has been building for some time: Policy divergence between the region’s two power centers — Abu Dhabi and Riyadh — over production strategy has steadily widened, and this exit turns that drift into a clean break(up). “The outcome has likely long been in the making,” Tchilinguirian says.

Even Opec’s shift toward capacity-based quotas — designed to better align targets with real production — has failed to bridge the gap between the UAE’s expanding capacity and the limits imposed by the system. The UAE has been planning to ramp up production by as much as 30%, something that doesn’t fit neatly inside Opec’s quota system, Vakulenko adds.

“By exiting Opec, the UAE could increase production beyond its current quota — potentially achieving a capacity closer to 4.8 mn barrels per day,” Al Gaaod adds. Once flows normalize, the country could feasibly add nearly 1 mn bbl / d — roughly 1% of global demand, with production rising gradually as conditions stabilize, particularly after normalization of energy flows through Hormuz, Schmit adds.

There’s also a deeper market-structure play behind the exit: “In previous Opec meetings, agreed upward changes with Saudi Arabia to the UAE’s production baseline level and quota were a short-term fix to a larger, long-term issue — namely, the UAE’s expanding production capacity to provide the necessary liquidity for the physically deliverable IFAD Murban futures contract,” Tchilinguirian highlights.

What does this mean?

Outside Opec, the UAE gains the freedom to increase output — and the incentive to do so — which could reshape supply dynamics once the current disruption cycle fades, Vakulenko said. This has implications for internal dynamics: without the UAE inside the tent, Saudi Arabia is left carrying more of the burden alone, raising questions about how long it can continue to act as the market’s swing producer without internal alignment, Rystad Energy’s Jorge Leon told Reuters.

At the same time, capacity constraints become more visible: Iran and Iraq have little meaningful spare capacity — which means Opec’s ability to smooth supply imbalances is directly weakened without the UAE in the mix, Vakulenko adds. That makes coordination more critical: “Most participants lack excess capacity and need pooled coordination as protection against volatility they cannot absorb individually,” Lehmacher notes.

This feeds directly into the volatility outlook: A structurally weaker Opec points to a potentially more volatile oil market once current disruptions ease, as the group’s ability to manage supply diminishes, Leon says. Market behavior is already shifting in response: “When both transit infrastructure and governance protocols fail, operators shift from spot exposure to long-term contracted capacity with built-in resilience premiums,” Lehmacher adds.

The upshot: “The main market impact would be a significant reduction in Opec’s influence over oil prices and coordination of output,” Al Gaaod says.

What’s next

“If other producers begin prioritizing market share over quota discipline, Opec’s ability to manage orderly markets through coordinated supply adjustments may increasingly be called into question,” Ole Hansen, head of commodity strategy at Saxo Bank, said in a research note seen by EnterpriseAM. If discipline erodes too far, the group’s capacity to shape the market shifts from enforcement to mere signaling. “This could be the thin end of the wedge if it triggers further disintegration of the group,” Oxley adds.

What follows may be a shift in how the market operates: The next phase of the oil market may be less about coordination and more about competition: Monitor how the UAE manages its production — and whether Saudi Arabia adjusts its strategy to compensate.

The great system rewrite: “While the UAE could potentially rejoin Opec if market conditions stabilize, such a departure would signal more than a temporary adjustment. It would represent a fundamental transformation in both energy strategy and geopolitical alignment, with profound implications for the structure and stability of global oil markets,” Al Gaaod adds.
