IEA Slashes 2026 Oil Demand on Hormuz Shock

The International Energy Agency cut its 2026 global oil demand forecast to 104 million barrels per day in the May Oil Market Report published Wednesday, a year-over-year contraction of 420 thousand barrels per day and 1.3 million barrels per day below the agency's pre-war baseline. Brent crude futures traded at $104.84 per barrel on ICE early Thursday, down 0.75 percent from Wednesday's settle, while WTI futures held near $102 on the CME as traders digested the steepest IEA demand cut since the pandemic.

The agency framed the revision as a direct consequence of the Strait of Hormuz disruption that began in late February. Output from affected Gulf countries was reported 14.4 million barrels per day below pre-war levels in April, with the IEA quantifying that more than 14 million barrels per day of oil remains shut in. Cumulative supply losses since the conflict began exceed 1 billion barrels.

Demand Contraction Concentrated in Q2 2026

The IEA expects the second quarter to bear the deepest demand bruise of the cycle. World demand is forecast to fall 2.45 million barrels per day year-over-year in Q2 2026, with the OECD contributing 930 thousand barrels per day of the decline and the non-OECD a further 1.5 million barrels per day. The petrochemical and aviation sectors are the most affected near term, but the agency warned that higher pump prices, a weaker economic environment and active demand-saving measures from importing governments are spreading through gasoline and diesel pools as the year progresses.

Seaborne import losses cluster heavily in North Asia. China is down 3.6 million barrels per day of crude arrivals, Japan is down 1.9 million, South Korea is off by 1 million and India by 760 thousand. For perspective, the four countries together absorbed more than half of all globally traded crude in 2025, so the import compression maps directly onto refinery throughput cuts and unplanned product imports.

Supply Side Equally Bleak

The IEA now forecasts global oil supply at 102.2 million barrels per day on average in 2026, a 3.9 million barrel per day annual fall and the worst supply outturn since the early 1990s. The forecast assumes Strait of Hormuz flows resume gradually from June, an assumption the agency itself flagged as uncertain given the lack of progress on a U.S. and Iran ceasefire framework.

OPEC+ collective output averaged 34.13 million barrels per day in April. Within that, Saudi Aramco parent Saudi Arabia produced 6.98 million barrels per day, the kingdom's lowest reported output since 1990. The drop reflects a combination of voluntary OPEC+ cuts, the operational impact of restricted Gulf shipping lanes and damage at infrastructure tributary to the East-West pipeline system. The UAE held at 2.44 million barrels per day, while the OPEC-9 with quotas totalled 14.33 million barrels per day.

Inventory Buffers Are Burning Fast

Global inventories drew at roughly 4 million barrels per day across March and April combined, the fastest sustained stock draw the IEA has recorded outside of a single-month event. OECD on-land stocks alone fell 146 million barrels in April, a drop that wipes out roughly two months of average pre-war drawdown in a single reporting period. North Sea Dated crude averaged $120.36 per barrel in April, a $16.50 per barrel jump from March's average.

The April price strike has since cooled by roughly $15 per barrel as a fragile two-week ceasefire emerged, but the IEA cautioned that the inventory cushion needed to absorb another flare-up has narrowed substantially.

Bank Forecasts Anchor Above $100

Two of Wall Street's largest commodity desks have aligned around a triple-digit Brent base case for the balance of 2026. Goldman Sachs warned that another full month of Hormuz disruption would lock Brent above $100 per barrel for the full year, with a downside extension scenario putting Q3 at $120 and Q4 at $115. Morgan Stanley pegged Dated Brent at $110 in Q2, $100 in Q3 and $90 in Q4 in its base case, with a bull case range of $130 to $150 per barrel if the blockade persists past June.

By comparison, when Saudi Aramco posted $32.1 billion in Q1 profit earlier this week on $115 average realisations, the company's CFO flagged that every additional month of Hormuz restrictions adds approximately $4 per barrel to its average realised price. Applying the same elasticity to today's $104 spot, even a partial June reopening would still leave full-year realisations comfortably above pre-war strip pricing.
