By Mari Hansen The trading floors in Singapore and London opened the morning following the UAE’s withdrawal from OPEC with the kind of silence that only occurs when no one is sure what to say. Brent had already started to climb. Already, phones were ringing. A decision that had been kept in a drawer for more than ten years had finally been signed somewhere in Abu Dhabi.
It wasn’t a tantrum. Ten years of pipeline construction is not necessary to implement tantrums. The UAE had invested about $150 billion to increase its production capacity to 4.85 million barrels per day, but OPEC’s quota system had been gently but firmly telling it to keep production at 3.2 million. There is no rounding error in that gap. It is an insult to the structure. It had also been expanding.

The amount of oil involved is not the only factor that distinguishes the Emirati exit from that of Qatar in 2019 or Angola in 2024. The infrastructure is the problem. By avoiding the Strait of Hormuz entirely, ADCOP’s Habshan-Fujairah pipeline transports Abu Dhabi’s inland crude directly to the Gulf of Oman. In a sense, independence was made possible by that one piece of steel and pumping stations. Fujairah’s exports have increased by 38% since Hormuz closed on February 28. In March, the port processed 1.62 million barrels per day. It was 1.17 million the previous month.
As you go through the analysis, you get the impression that Abu Dhabi had been planning for this exact situation without ever explicitly stating it. Up until May 4, the Al Mandous underground storage caverns appeared overly cautious despite being designed to store 42 million barrels and withstand air strikes.
Iranian cruise missiles and drones attacked the Fujairah Oil Industry Zone that morning, destroying a portion of the VTTI terminal and driving Brent above $114. The caverns were secure. The plan worked. Planning something like that doesn’t happen in a panic.
Iran’s choice of target also conveys a message. Infrastructure that is irrelevant is not bombed. Tehran’s attack on Fujairah effectively validated what the rest of the market was beginning to suspect: this port is the tangible element that lends credibility to Emirati sovereignty over its own oil. The majority of other Gulf producers are unable to make the same claim. Bahrain, Qatar, and Kuwait are still reliant on Hormuz. Riyadh has some breathing room thanks to Saudi Arabia’s East-West pipeline to Yanbu, but no other cartel member has anything comparable.
Now, the more important question is whether OPEC absorbs this shock in the same manner as it did the previous ones, or if something deeper has broken. OPEC has always operated as a perpetual prisoner’s dilemma, with each member discreetly balancing the short-term advantages of cheating against the long-term advantages of sticking to the rules. Cooperation works when everyone believes the cartel will still be standing next year, and the year after. Shorten that horizon, and the math flips.
Vandana Hari of Vanda Insights put it more bluntly than most analysts would dare: in a world where national interest keeps elbowing past collective coordination, the case for self-sacrifice gets thinner every quarter. Kazakhstan was flagged as the next likely defector almost immediately. Astana has reaffirmed its commitment, but everyone knows that reaffirmation is mostly Moscow’s doing. The framework is necessary for Russia. Its war economy runs on the windfall.
The members who haven’t left but aren’t playing as much are the awkward middle ground. For many years, Iraq has been a persistent overproducer. Kazakhstan, with Western operators running its fields for shareholder returns, has been quietly ignoring its allocation. Nigeria, with its Dangote refinery shifting the country toward refined fuel margins, has less and less reason to care about crude price discipline. Without anyone having to slam a door, the cartel is disintegrating.
What prevents the others from leaving? primarily Saudi Arabia, which has made the largest voluntary cuts and has learned a lot from its shale war in 2014. Riyadh remembers what flooding the market actually costs. Naturally, Russia cannot afford a breakdown in coordination at this time.
As this develops, it’s difficult to ignore the fact that OPEC is encountering something akin to Le Chatelier’s principle: a system that absorbs stress and constantly finds a new equilibrium but never quite returns to its initial state. Because Qatar was a gas story, its exit was manageable. Angola was a humble country. The United Arab Emirates is unique. Third-largest producer. $77 billion in annual revenue. One of only two members with real spare capacity. And the only one besides Saudi Arabia with a serious way out of Hormuz.
The cartel is still in place. Most likely, it won’t—at least not this year. However, everyone in the room is aware that it is now smaller and somewhat less credible. Whether Western economies feel the full weight of that recalibration this summer or next, the calculation has already shifted. The silent war isn’t really silent anymore. All you need to do is know where to listen.
