OPEC+ has cut oil production by approximately 9.7 million barrels per day — a 30 percent reduction from pre-conflict levels — since the Strait of Hormuz conflict escalated in April, according to data shared at a closed-door OPEC advisory council meeting on May 13. The International Energy Agency projects global demand will fall by 420,000 barrels per day through year-end as high prices and economic uncertainty crimp consumption across Asia and Europe. Inventory draws are proceeding at the fastest pace since the 1973 oil embargo, raising the prospect of a supply shock that analysts say cannot be quickly reversed.
The Hormuz Strait, through which roughly 21 million barrels of oil pass daily, has become the focal point of the most severe disruption to global energy markets in over five decades. Shipping insurers have added significant premiums for vessels transiting the Gulf, and several major carriers have rerouted around the Cape of Good Hope, adding 14 days to delivery times and increasing costs by an estimated $4–6 per barrel. The rerouting has created a two-tier pricing structure: Brent crude anchored to Gulf shipments trades at a premium to Dated Brent, which reflects North Sea and West African supply.
Production Losses by Country
The production collapse is not evenly distributed. Iran’s output has effectively vanished from international markets, removing approximately 3.5 million barrels per day from global supply. Saudi Arabia and the UAE have each contributed additional voluntary cuts exceeding 1 million barrels per day, though Riyadh has described these as “precautionary” and reversible pending “stability in transportation corridors.” Iraq’s compliance with OPEC+ quotas has improved to 94 percent, but infrastructure constraints limit its ability to increase beyond current levels.
“We are in a structural deficit that we cannot fill from spare capacity alone. The market has not priced in how long this will last,” said an OPEC delegate who attended the May 13 meeting and requested anonymity to discuss internal deliberations.
Strategic Petroleum Reserve Releases
The IEA’s May 14 report estimates that member nations have collectively released 180 million barrels from strategic petroleum reserves since April 20, but describes this as “a bridge measure, not a solution.” The United States has contributed approximately 65 million barrels to coordinated releases — the largest single contribution — while Japan, South Korea, and the United Kingdom have each added smaller quantities. The IEA’s emergency oil stock mechanism requires member nations to hold 90 days of net imports; several European countries are now approaching that threshold, reducing their ability to absorb further disruptions without drawing down to operational minimums.
Global inventory data from the IEA shows commercial stocks in OECD nations fell by 42 million barrels in April — the steepest monthly decline since 2020. At current draw rates, the agency’s models indicate OECD commercial inventories will fall below the five-year average by the end of June, a threshold the IEA considers a trigger for “tight market conditions.” Trading house Trafigura estimates that unscheduled inventory draws could accelerate that timeline by three to four weeks.
“The question is not whether there will be a supply gap — there already is one. The question is how governments choose to manage the social and economic consequences when retail fuel prices cross thresholds that provoke political responses,” said a senior IEA official who briefed journalists in Paris on May 14.
Market Response and Price Pressure
Brent crude has risen 23 percent since the Hormuz incident began, trading above $94 per barrel on May 13 before retreating slightly to around $91 in early Asian trading on May 14. WTI, which is anchored to US Gulf of Mexico shipments that have not been directly affected by the Strait disruption, trades at a discount of approximately $6 per barrel to Brent — the widest spread since 2020. Analysts at Goldman Sachs have raised their year-end Brent price forecast to $98 per barrel, citing the structural nature of the supply disruption and the limited response from OPEC+ producers with remaining spare capacity.
Consumer nations are responding with a mix of policy tools. India’s government has reduced fuel taxes twice in the past six weeks, absorbing approximately $2.3 billion in revenue to keep pump prices below the psychological threshold of 100 rupees per liter. Germany’s coalition government is debating whether to extend the €0.30 per liter fuel tax relief that is scheduled to expire on June 30, with business groups warning that removing the relief prematurely could push inflation back above 4 percent in the industrial sector.
IEA Demand Revision and Consumption Trends
The 420,000-barrel-per-day demand reduction is the sharpest single revision the IEA has made since the post-pandemic recovery period. The agency cites three primary drivers: demand destruction in price-sensitive markets in South and Southeast Asia, where consumers have reduced vehicle usage in response to higher fuel costs; industrial demand contraction in Europe as manufacturers reduce output in response to energy cost pressures; and a moderate but measurable shift toward public transit and remote work in urban centers across North America, Europe, and East Asia. The IEA’s full-year demand growth forecast has been revised to 0.8 million barrels per day, down from its pre-conflict estimate of 1.2 million barrels per day.
China’s domestic oil consumption has been more resilient than expected, with state-owned refineries increasing throughput to compensate for reduced import availability. China’s crude imports from Russia and Brazil have increased substantially in May, partially offsetting the loss of Middle Eastern supply. However, China’s strategic reserves are filling rapidly, and trading sources suggest Beijing may begin reducing import volumes as early as June once storage targets are reached — a development that could ease global supply tightness in the second half of the year.
Outlook and Near-Term Risks
The IEA’s base case projects the market will remain in deficit through at least the third quarter of 2026, with inventories continuing to draw. The agency’s downside scenario — in which the Strait of Hormuz remains effectively blocked for more than six months — estimates Brent could breach $110 per barrel by August, with retail gasoline prices in the United States averaging above $4.50 per gallon nationally. The upside scenario assumes a negotiated de-escalation and partial reopening of the Strait within 60 to 90 days, which would allow OPEC+ to begin restoring production and inventories to build through the fourth quarter.
For policymakers, the structural deficit poses a difficult trade-off: drawing down strategic reserves stabilizes prices in the short term but reduces the principal tool available for responding to future shocks. The IEA’s emergency stock mechanism is not designed for a sustained, multi-quarter supply disruption, and several member governments have privately expressed concern that the current release pace is not sustainable through year-end without triggering domestic supply shortages.
“We have seen this movie before. The 1973 embargo lasted 10 months. The market adjusted, but the adjustment required a recession in OECD economies and a fundamental shift in energy policy. We are not at that point yet — but we are moving in that direction,” said a former IEA chief economist who now advises the European Commission’s energy directorate.
