Alex Epstein on OPEC: UAE's exit is opportunistic, the Strait of Hormuz remains the world's most critical energy chokepoint

Alex Epstein on OPEC, Hormuz, and the long-term oil supply risk

The Strait of Hormuz

The Strait of Hormuz remains the irreplaceable bottleneck in global energy supply, and a ceasefire alone doesn't fix it. Epstein argues that any deal leaving Iran with effective control over the strait — even one that opens it temporarily — is worse than the pre-war baseline, when markets at least assumed the US had meaningful deterrence. What matters is not a momentary opening but an enduring one, on American terms.

The administration eventually came around to that view. Within roughly a week of an earlier conversation Epstein had with people inside it, officials converged on the position that Hormuz is non-negotiable. Before that, some were floating Venezuela and other alternatives as partial substitutes — arguments Epstein dismisses as fantasy. Venezuela might represent 1% of global supply after years of effort. The strait accounts for roughly 14–20% of global oil flow, and there is no replacement.

The economic damage from the disruption is already accumulating in Asia, which bears the brunt of the supply cut. Epstein cites reports of shortages in materials like sulfur and helium that also transit the strait. China built up oil reserves that provide some buffer, but those are temporary. Even if the strait reopened today, supply takes time to ramp back up, meaning price pressure has a delayed tail regardless of how quickly the conflict resolves.

“UAE is doing this at an opportunistic time — they're doing it in the time of a supply shortage because nobody really cares... My biggest fear is insufficient reserve replacement with high oil demand, because you're talking $200 oil... It needs to open on our terms. That's the only way you have a victory.”

UAE's exit from OPEC

The UAE's decision to leave OPEC is opportunistic rather than structural, in Epstein's view. The country is exiting at a moment of supply shortage, when no one needs to cut production and Saudi Arabia has little incentive to punish defection. The real test comes during a supply glut.

The UAE has roughly 1.5 million barrels per day of spare capacity and one pipeline bypassing the strait, but none of that production can reach markets meaningfully right now. Leaving OPEC during a shortage costs nothing and signals future autonomy. The question is whether that autonomy holds when Saudi Arabia can threaten to flood the market to pressure members back into compliance. Epstein says that dynamic has worked before.

There is a credible counter-argument that the UAE is now better positioned to resist Saudi pressure than in past cycles — it has diversified its economy, carries fewer welfare obligations than Riyadh, and has lower fiscal dependence on oil revenue per barrel. Saudi Arabia's breakeven is high when you account for all the domestic spending obligations attached to oil income, not just production costs. The same is true for the UAE to a lesser degree. Whether Abu Dhabi can actually call Riyadh's bluff in a prolonged glut remains genuinely uncertain.

OPEC's structural logic

Epstein traces OPEC through the full history of oil market volatility management. The Texas Railroad Commission served as the effective swing producer in the early US era, rationing supply to smooth prices. Saudi Arabia assumed that role as Middle Eastern production scaled. US shale briefly disrupted the dynamic before "fiscal discipline" among producers functionally replicated cartel behavior without formal coordination.

The core logic of any swing producer, cartel or not, is to cut supply during gluts to prevent prices from collapsing in ways that destroy investment incentives. That dynamic is not incidental to OPEC — it is the reason it exists, and it is also why a large supply increase from the UAE would hurt US shale producers most. American shale has higher production costs than Gulf producers, and every $10 drop in oil price is nearly pure loss at the margin.

The long-term supply risk

The immediate fear is Hormuz keeping prices elevated. Epstein's bigger concern is what happens two to five years out. The ESG era pushed major financial institutions and national oil companies away from long-term upstream investment. The International Energy Agency called for no new oil and gas development financing as recently as 2021. Oil wells deplete over time and require continuous reserve replacement to hold production flat — if that replacement has been systematically underfunded, the shortfall shows up with a lag.

Epstein says the best estimates he has seen point toward structurally higher prices on a longer horizon, potentially toward $200 a barrel, driven not by a single shock but by years of under-investment compounding against sustained demand. That is the scenario he considers most dangerous — not a temporary crisis, but a durable squeeze with no quick supply response available.
