Brent fell to $91.12 on May 29, down nearly 17.5% in a month, erasing $35 per barrel and roughly $900 billion in notional oil market value on the back of a deal that has not been signed, approved, or even acknowledged by the party that matters most. The market is pricing in peace while the mines are still in the water and Trump is still in the Situation Room.
Reports surfaced May 29 that the US and Iran reached a tentative 60-day ceasefire extension, with unrestricted shipping through Hormuz and mine removal as part of the framework. The problem is that Trump has not approved the proposed terms, Tehran has issued no official response, and an adviser to Iran's supreme leader accused Trump of "betraying diplomacy for the third time" just hours after the meeting ended. Yet oil traders sold like the war was over.
This is not how adults manage risk. The Strait of Hormuz remains effectively closed despite a conditional ceasefire, with vessel traffic at roughly 5% of pre-conflict levels. The US blockaded Iranian ports from April 13 to May 29. Iran laid sea mines in the strait. Analysts warn that any recovery would be slow, requiring mine clearing, infrastructure repair, and restarting shut-in production. None of that happens because Axios published a scoop.
The Brent curve now reflects a world where 20 million barrels per day of choked supply magically returns to normal within weeks, based on a memorandum of understanding that one side denies and the other has not approved. March 2026 recorded the largest monthly oil price increase in history, with Brent hitting $114. Two months later, the entire war premium has been surgically excised from the forward curve on vibes and leaks.
Meanwhile, the structural picture for OPEC deteriorated in ways the market has not fully absorbed. The UAE exited OPEC on May 1, removing the cartel's third-largest producer after nearly six decades. Abu Dhabi has 4.85 million barrels per day of capacity, but its May quota was just 3.5 million. The UAE could flood the market with 1.6 million bpd of unconstrained production once Hormuz reopens, enough to permanently fracture whatever pricing discipline OPEC has left.
The first OPEC meeting since the UAE's departure took place May 3, where the seven remaining producers agreed to raise output by 188,000 bpd in June. That is not the behavior of a cartel confident in $100 oil. The group said the rollback could be paused, reversed, or accelerated depending on market conditions and constraints from the Iran war. Translation: they have no idea what happens next and are making it up month to month.
Oil hit $126 in March because the market believed Hormuz would stay closed and OPEC cohesion would hold; it hit $91 in May because the market believes a deal is days away and spare capacity will flood back. Both cannot be true. Either Trump signs a framework that includes full navigation rights, mine removal, nuclear concessions, and sanctions relief, or he does not. Either Iran complies and the barrels return, or Tehran slow-rolls implementation and uses toll collection to maintain leverage.
The IEA, World Bank, IMF, and OECD warned May 29 that global oil inventories are being depleted at a record pace. If shipping flows do not normalize, continued depletion ahead of Northern Hemisphere summer demand presents risks for fuel security and economic resilience. That warning came the same day the market decided everything was fine and sold $35 off the prompt.
The setup is binary and the positioning is one-sided. If the deal collapses or implementation drags into July, the market will reprice 20 million barrels per day of missing supply in about four sessions. If the deal holds and barrels return faster than expected, the UAE's uncapped production and OPEC's crumbling discipline will crater the curve into year-end. There is no middle scenario where Brent sits at $91 and everyone is comfortable.
Markets are supposed to discount the future, not hallucinate it. Right now they are doing the latter, and the traders selling this move have not read the same news the rest of us have. Trump has not signed. Iran has not agreed. The mines are still there. And OPEC just lost its third-largest member during the largest supply disruption in history. Pricing all of that at $91 is not insight. It is hope, repackaged as a forward curve.
