These two countries are the most likely to leave OPEC’s orbit next
OPEC and its wider OPEC+ alliance have held an uneasy line on supply discipline since the pandemic. The cartel still shapes the marginal barrel, but its center of gravity is shifting as member states chafe at quotas, non-OPEC partners hedge their commitments, and investment clocks tick faster in the energy transition. Angola’s December 2023 exit showed that walking away is no longer unthinkable. Looking ahead, two producers stand out as the most plausible to drift out of OPEC’s orbit—one from the core, one from the periphery: the United Arab Emirates and Brazil.
Why “leaving the orbit” matters now
– OPEC’s leverage rests on cohesion and credible spare capacity. Every formal defection or de facto noncompliance weakens both.
– Investment timelines are colliding with quota math. Producers that have spent heavily to add capacity are less willing to sit on barrels.
– The energy transition changes incentives. “Pump sooner” logic grows as demand uncertainty rises in the 2030s.
Candidate 1: United Arab Emirates
The UAE is the only Gulf heavyweight whose strategic trajectory is increasingly misaligned with today’s OPEC+ framework. Its push-and-pull with the group has been visible for years.
What makes the UAE a prime candidate
– Capacity versus quota: ADNOC has poured tens of billions into upstream projects and is targeting roughly 5 million barrels per day of capacity later this decade. Even after securing a higher OPEC baseline in 2023, cuts have repeatedly held actual UAE output well below its technical potential. That erodes returns on sunk capital.
– Recurrent quota friction: Abu Dhabi openly resisted the group’s baselines in 2021 and lobbied hard in 2023. The pattern is consistent: the UAE will not accept being structurally under-allocated relative to what it can produce.
– Transition timing: Low-cost, low-carbon-intensity barrels like the UAE’s are most valuable in the 2020s. From a national value-maximization view, deferring production risks leaving barrels unmonetized later.
– Strategic confidence: The UAE has diversified diplomatically and economically. It can bear reputational costs and market pushback better than most members, and it calculates that Riyadh would ultimately prefer bargaining to a prolonged price war.
Why it might still stay
– Gulf alignment: The Abu Dhabi–Riyadh relationship is competitive but cooperative. Both sides know a rupture could destroy value. A negotiated uplift in the UAE’s baseline is the path of least resistance.
– OPEC’s platform value: Membership still provides influence on market signaling and global energy diplomacy that no bilateral channel replicates.
What would trigger a break
– Failure to win a substantial, durable baseline increase in the next quota revamp.
– Another round of deep, open-ended cuts that strand new UAE capacity.
– A public split with Saudi Arabia over market-share strategy, followed by unilateral Emirati overproduction to force a reset.
Market impact if it happens
– Short term: A rapid UAE ramp of 0.5–1.0 million barrels per day would pressure Brent by several dollars a barrel, depending on Saudi response and non-OPEC supply trends.
– Medium term: OPEC would lose part of its Gulf spare-capacity buffer and its reputation for ironclad cohesion. The price floor would depend more heavily on Saudi unilateral management and Russia’s export discipline.
Candidate 2: Brazil
Brazil is not an OPEC member, but it joined the OPEC+ “cooperation charter” in 2024, attending meetings without binding cuts. That positioning makes it the most likely near-term departure from OPEC’s broader gravitational field.
What makes Brazil likely to step back
– Growth first: Pre-salt projects are ramping with multi-year momentum. Brazil already produces over 3 million barrels per day and is on track toward roughly 4 million late this decade. These are long-cycle projects with low break-evens; throttling them for quotas makes little economic sense.
– Minimal benefit from alignment: As long as Brazil refuses to accept a formal quota, OPEC+ cannot materially influence its output. The “observer” seat offers limited market advantage while inviting political scrutiny.
– Domestic politics: Brasília must balance climate leadership credentials with oil-led development. Distancing from a supply-restraining cartel is the cleanest political compromise at home and abroad.
– Precedent and posture: Mexico effectively opted out of meaningful OPEC+ cuts after 2020; Brazil has already signaled it will not cut. If pressure mounts to formalize participation, walking away is the likely answer.
Why it might linger on the fringe
– Information and influence: Observing OPEC+ gives Petrobras and regulators early insight into policy shifts and a seat in narrative formation—useful in a volatile market.
– Low-cost option: Remaining an observer requires no output sacrifice as long as OPEC+ does not demand formal commitments.
What would trigger a break
– A concerted OPEC+ push to assign Brazil a quota or to tie future cooperation to verifiable curbs.
– Domestic backlash tying OPEC+ engagement to environmental credibility or fuel-price politics.
– A sustained price downturn that forces deeper OPEC+ cuts Brazil is unwilling to endorse even symbolically.
Market impact if it happens
– Direct volumes: Little immediate change; Brazil is already charting its own course. But the symbolism would matter, underscoring limits to OPEC+ influence over the Atlantic Basin and reinforcing the view that non-OPEC growth will not be capped by cartel diplomacy.
Runners-up to watch
– Iraq: Chronic overproduction versus quotas, fiscal pressures, and internal politics make compliance fragile. Formal exit is unlikely, but de facto distance from OPEC discipline could widen if cuts deepen.
– Small African members (Equatorial Guinea, Gabon, Republic of the Congo): With declining output and constrained investment, the dues-versus-benefits math of membership can turn negative. Angola’s exit provides a template.
– Russia: Sanctions, war financing needs, and the shift from price to export-revenue management push Moscow toward unilateralism. Still, the signaling value of OPEC+ for Russia remains high, and coordination on paper is cheap.
What to watch next
– Baseline renegotiations inside OPEC+ in the next review cycle, especially any Saudi-Emirati bilateral deals.
– ADNOC capacity announcements and project start-ups versus declared UAE production targets.
– OPEC+ communiqués that try to formalize expectations for “cooperating countries,” and Brazil’s response.
– Compliance data volatility in Iraq and Nigeria and how forcefully OPEC enforces “compensation cuts.”
– Demand-side surprises in 2025–2026: a soft patch would amplify quota stress; a tight market would delay but not resolve underlying tensions.
Bottom line
The centrifugal forces pulling at OPEC’s system are most acute at its edges—fast-growing non-members like Brazil—and at the ambitious core—especially the UAE, whose investment clock is out of sync with today’s quotas. Either departure would weaken the cartel’s ability to choreograph supply, though in different ways: Brazil’s exit would be a symbolic blow to OPEC+ reach, while a UAE break would materially test the group’s market power. OPEC can keep both in its orbit by offering flexibility—higher baselines for rising, low-cost producers and a low-commitment “open tent” for growth-focused outsiders. Whether that compromise holds will shape oil balances and price stability for the rest of the decade.
