This is the context that makes the July hike both inevitable and largely symbolic. The alliance is sticking to a predetermined schedule of unwinding earlier production cuts—a plan conceived in a radically different market environment. The UAE’s recent departure from the group necessitated a downward revision, trimming the July hike from 206,000 bpd to 188,000 bpd to account for the lost member’s quota share . But no diplomatic recalibration can bridge the gap between a rising target and a collapsing supply base.

The Nature of the Shock Is Structural, Not Temporary

The International Energy Agency (IEA) and the World Bank have both labeled the Hormuz disruption the largest oil supply shock in history, unequivocally more consequential than the twin oil crises of the 1970s combined . By mid-May 2026, more than 14 million bpd of Gulf production was shut in, with cumulative supply losses since late February totaling 12.8 million bpd on the IEA's data series .

Market experts are emphatic that the disruption cannot be quickly reversed. Helima Croft of RBC Capital Markets described the restoration process in stark terms: it is “not like turning a switch on and off.” Even if the strait were to reopen soon, Croft and other analysts do not expect production to recover before year-end due to the extensive damage to energy infrastructure, the complexity of restarting shut-in wells, and the ongoing security risks . The World Bank reinforced this view, noting that Gulf production is unlikely to return before the end of June and that structural constraints will persist long after any ceasefire .

This structural damage is compounded by the sheer scale of the initial blow. On a normal day, approximately 17-20 million barrels of crude and products transit through the Strait of Hormuz. The de facto closure removed an estimated 16-18 million bpd from global flows almost overnight . Emergency measures and rerouting have offset only a fraction of that loss, leaving a net global supply deficit of roughly 10.8 million bpd . With repair costs for Middle Eastern energy infrastructure now projected to exceed $25 billion, the path to normalization is measured in quarters, not weeks .

Saudi Arabia Hits Lowest Output in Decades

The production collapse is most acute in Saudi Arabia. Reports from multiple market intelligence sources indicate that Saudi crude output has fallen to levels not seen since the 1990 Gulf War, when fields were set ablaze by retreating Iraqi forces . While the exact barrel-per-day figure for the kingdom was not independently confirmed in the latest OPEC secondary sources, the direction of travel is unambiguous. The same Gulf producers that account for the 9.9 million bpd aggregate decline include the Saudi fields that once acted as the world’s swing producer.

The erosion of Saudi spare capacity has profound implications. For decades, the kingdom's ability to rapidly ramp up or throttle back production functioned as the global oil market’s ultimate safety valve. With that buffer now severely diminished—alongside the complete offlining of neighboring Gulf producers—the market has entered what the World Bank calls a period of extreme fragility .

Demand Is Also Contracting Under the Strain

The supply collapse is not the only moving part. The IEA’s May 2026 Oil Market Report delivered a sharp downward revision to global oil demand, now forecasting a contraction of approximately 420,000 bpd for the year. Total demand is projected at roughly 104 million bpd, about 1.3 million bpd below the agency’s pre-war forecast . The steepest decline is expected in the second quarter of 2026, with year-on-year demand shrinking by around 2.45 million bpd as surging oil prices, slowing economic activity, and widespread flight cancellations destroy consumption .

This demand destruction is a direct consequence of the supply crisis. Brent crude prices have oscillated around $110 per barrel, and Dubai crude—the benchmark for Middle Eastern sour grades—briefly spiked to $170 . Refineries in Asia, starved of feedstock, have cut runs by roughly 6 million bpd . The result is a perverse dynamic: even as the global economy weakens and oil consumption falls, supply is falling faster, leaving the market severely undersupplied. The IEA's latest balances imply that supply will trail total demand by 1.78 million bpd in 2026, erasing what was once forecast as a comfortable surplus .

Inventories Are Draining at an Unprecedented Pace

The mismatch between supply and demand is consuming global stockpiles at a rate that alarms analysts. The U.S. Energy Information Administration (EIA), in its May 2026 Short-Term Energy Outlook, revised its forecast for global inventory draws sharply upward. The agency now expects global oil inventories to decrease by 2.6 million bpd in 2026, a massive jump from the 0.3 million bpd draw it projected just a month earlier . The revision reflects a later assumed reopening of the Strait of Hormuz and a longer recovery timeline for shut-in production. Within that annual average, the EIA expects inventory draws to average 8.5 million bpd in the second quarter alone .

The IEA’s language mirrors this alarm. The agency stated that inventories are being drained at an “unprecedented pace” and that the market will remain severely undersupplied through at least the end of the third quarter of 2026, even if hostilities were to end soon .

Little Room for Error: Spare Capacity Is Nearly Gone

The combination of structural supply loss, rapid stockpile depletion, and severely eroded spare capacity has created a consensus among experts that the market has virtually no margin for further disruption. With more than 14 million bpd of production offline and Gulf buffers nearly exhausted, analysts emphasize that “little room for error” remains . Any additional shock—further escalation of the conflict, a secondary chokepoint disruption, or an unexpected outage in other producing regions—could trigger an even more extreme price spike.

The World Bank highlighted this vulnerability, warning that as global buffers are drawn down and spare production capacity shrinks, the market has entered a period of extreme fragility . The OPEC+ decision to raise quotas for July, while technically adhering to the group’s unwind schedule, does nothing to alleviate this fragility. The oil that the quotas theoretically permit simply cannot reach the market.

The Road Ahead

As the June 7 OPEC+ meeting approaches, the alliance’s decision is widely viewed as a foregone conclusion. The 188,000 bpd target increase will be approved, adding another layer of notional supply to a market starved of real barrels. The more consequential questions lie beyond the quota announcement: how long will the structural damage to Gulf infrastructure take to repair, how much permanent demand destruction will elevated prices cause, and what will the global energy security landscape look like after the largest oil supply disruption in history finally begins to reverse?

For now, the market remains suspended between a rising paper quota and a collapsing physical supply—a paradox that defines the 2026 oil crisis.
