The United Arab Emirates’ shock decision to leave OPEC is reverberating across global energy markets, exposing fractures in the powerful oil cartel as production quotas risk prompting other members to follow suit.
The country’s decision follows weeks of missile and drone strikes by fellow OPEC member Iran, with the blockade of the Strait of Hormuz disrupting its exports, putting pressure on the backbone of its economy.
«The UAE exit is another chapter in the changing membership of the group,» said Andy Lipow, president of Lipow Oil Associates. «If countries that are abiding by their quota get disgusted with those that don’t, we could see additional exits that could eventually make OPEC irrelevant as a cartel,» he told CNBC via email.
Countries, including Qatar, Ecuador and Angola have left the group in past years, citing frustration with quotas or shifting national priorities. Angola left in 2024, while Qatar terminated its membership in 2019.
The cartel has long grappled with uneven compliance, with some members historically exceeding their production quotas, including Iraq and Kazakhstan.
«While the UAE has left OPEC, they were not the first and may not be the last,» Lipow added.
Countries that are tired of seeing their fellow OPEC and OPEC+ members consistently cheat on their quotas are candidates to leave these groups.

At the heart of the UAE’s decision lies a familiar tension: members that have invested heavily in boosting production capacity are increasingly reluctant to be constrained by quotas designed to support prices.
The country pumped about 2.37 million barrels per day in March, compared with its sustainable capacity of roughly 4.3 million bpd, according to latest IEA data.
‘Flight risks’
Analysts pointed to several potential «flight risk» countries, chafing at OPEC+ restrictions, that could consider giving up their memberships.
Matt Smith, lead oil analyst at Kpler, flagged Kazakhstan as a key candidate, noting its persistent overproduction. «Kazakhstan has been vastly over producing last year, and so they may be seeing this as a potential out for them to leave the group as well,» Smith said, adding that Nigeria could also be one to watch out for.
Nigeria, Africa’s largest crude oil producer, has increasingly prioritized domestic refining, particularly through the Dangote refinery, reducing its reliance on export markets and potentially weakening its incentive to remain bound by quotas.
Smith explained that the ramp-up of the Dangote refinery means it can process more oil at home and capture higher-value fuel margins. That reduces its reliance on OPEC’s strategy of supporting crude prices through supply curbs and instead increases its focus on maximizing volumes and downstream returns.
«Nigeria is in a similar position about not wanting to be hamstrung: it is a potential flight risk because it is becoming more self-sufficient,» Smith noted. «By redirecting its domestic crude production to the Dangote refinery, Nigeria is less reliant upon global market dynamics.»
Venezuela is another possible contender, said market watchers. With output recovering faster than expected and a potentially more U.S.-friendly political environment emerging, Caracas could seek greater flexibility.
«Venezuela could be next off the rank in wake of leadership change there to a more U.S. friendly position,» said Saul Kavonic, energy analyst at MST Marquee.
Kpler’s Smith also said that Venezuela was a potential candidate because it has been ramping up production and exports at a quicker pace than expected. Venezuela’s oil exports rose above a million barrels per day in March for the first time since September.
Kazakhstan, Nigeria and Venezuela’s energy ministries did not immediately respond to CNBC’s requests for comments.
OPEC+ is enforcing core production quotas that reportedly cut output by about 2 million barrels per day until the end of 2026.
Eight key OPEC+ producers including Saudi Arabia and Russia agreed on April 5 to begin a cautious easing of their voluntary output cuts, gradually returning about 206,000 barrels per day to the market in May from a broader 1.65 million bpd reduction first introduced in 2023, according to an official OPEC statement.
Fragmented but essential?
The UAE’s departure comes as OPEC is grappling with fragmentation. Several members including Iran, Libya and Venezuela have been exempt from quotas due to sanctions or conflict, complicating efforts to maintain cohesion.
Lipow noted that frustration over uneven compliance could further drive exits. «Countries that are tired of seeing their fellow OPEC and OPEC+ members consistently cheat on their quotas are candidates to leave these groups.»
Diminished cohesion could lead to more volatile oil markets. Bob McNally, president of Rapidan Energy Group, said any erosion in OPEC+ discipline would likely amplify price swings. «The main impact will be to increase the volatility of oil prices,» he said.
Still, others argue that OPEC’s core function, which is stabilizing markets, remains intact, even with fewer members.
Claudio Galimberti, senior vice president at Rystad Energy, said the group’s track record, particularly during crises such as the Covid pandemic, suggests resilience.
«The group for the past 10 years managed to balance the market in an incredible way,» he said. «If OPEC plus hadn’t been present during Covid, we would have had enormous volatility in the market.»
