Global oil demand is projected to decline by approximately 1 million barrels per day in 2026, marking the first drop since the 2020 pandemic peak, according to the International Energy Agency (IEA). This downturn stems from rising oil prices and physical supply disruptions caused by conflict between the U.S. and Iran, which hindered crude shipments through the Strait of Hormuz.
Why the Strait of Hormuz Conflict is Stalling Global Oil Flow
The war between the U.S. and Iran left crude oil tankers stranded in the Persian Gulf for over three months, blocking a critical artery for global energy. Jim Burkhard, vice president and head of crude oil research at S&P Global Energy, stated that the future of the strait is likely more uncertain now than it was at the start of the conflict.
Burkhard noted that while a fragile ceasefire in June allowed some ships to exit, Iran continues efforts to control the strait. Because the U.S. has not fully restored normal operations, a return to prewar conditions remains unlikely.
China’s Strategy to Combat High Energy Prices
China is the primary driver of the global demand slump. The country’s oil consumption fell by 1.5 million barrels per day, a 9% decline, according to the IEA report. Burkhard explained that China responded to rising spring prices by cutting global market purchases by nearly 6 million barrels per day, opting instead to utilize its own massive inventory stocks.
Daniel Sternoff, a senior fellow at the Center on Global Energy Policy at Columbia University, identified two specific ways China reduced its reliance on imports:
- Strategic Reserves: China temporarily stopped filling its strategic petroleum reserve, which previously absorbed nearly 1 million barrels per day.
- EV Adoption: The crisis accelerated a shift toward electric vehicles. Sternoff estimates China is on track to lose between 500,000 and 600,000 barrels per day in gasoline and diesel demand.
The U.S. Exception: Why Gas Prices Didn’t Stop Drivers
While Asia saw sharp declines, the U.S. remained an outlier. Gasoline consumption increased during the second quarter of 2026, even as pump prices rose 50% above prewar levels. AAA data shows average regular gasoline prices surpassed $4.50 per gallon in May.
Sternoff attributes this resilience to two factors. First, the percentage of household income spent on gas has declined over several years. Second, the transition from remote work back to in-office roles increased road usage. He noted that higher-income quintiles may complain about prices but generally do not drive less because of them.
Market Dynamics: Why Oil Prices Aren’t Spiking Higher
Despite renewed tensions between the U.S. and Iran, oil prices have not seen a massive spike. Burkhard describes the current state as a “gray zone conflict” that the market has already priced in. He compared this to the “unthinkable” shock experienced in early March.
The market is currently characterized by a “gush of supply” of crude oil but a lack of available buyers. This imbalance is worsened by refining bottlenecks. Burkhard pointed out that Ukrainian drone strikes damaged Russian refineries, and Middle Eastern refineries remain impaired from war, keeping the prices of refined products like diesel and gasoline inflated even as crude prices stabilize.
Comparison: Global Demand Trends
| Region | Demand Trend | Primary Driver |
|---|---|---|
| China | Significant Decrease | Inventory use & EV growth |
| United States | Increase | Return to office & income levels |
| Asia (General) | Decrease | Middle East supply disruptions |
Frequently Asked Questions
Why is global oil demand falling if the U.S. is using more?
The decline is driven heavily by Asia, specifically China, which reduced its consumption by 1.5 million barrels per day due to high prices and a shift toward electric vehicles.
How did the U.S.-Iran conflict affect oil supply?
The conflict caused ships to be stranded in the Persian Gulf for over three months, restricting flow through the Strait of Hormuz, a primary route for oil and gas.
Why are gas prices still high if oil demand is dropping?
Refinery damage in Russia (via drone strikes) and the Middle East has limited the production of refined fuels, keeping gasoline and diesel prices inflated despite the availability of crude oil.
How is China reducing its oil imports?
China is using its internal strategic petroleum reserves and increasing its adoption of electric vehicles to lower its reliance on the global market.
