China's oil imports collapse 40% as Tehran crisis reshapes demand

Beijing slashed crude purchases by 4.6 million barrels a day since the Strait of Hormuz closure, turning the world's top importer into a swing supplier of demand-side relief.

China cut crude imports 40% to about 7 million barrels a day by June from an 11.6 million average in 2025, using strategic stockpiles and surging electric-vehicle adoption to absorb the shock of the Hormuz closure during the Iran war.

"We tend to joke among ourselves that China is the OPEC of oil demand," said Homayoun Falakshahi, head of crude oil analysis at Kpler.

The 4.6 million barrel-a-day drop — unprecedented outside a major recession — came as China's economy still expanded 4.3% in the second quarter. Beijing drew on roughly 1.1 billion barrels of crude in storage, restricted refinery runs and banned fuel exports at the start of the Iran conflict. More than half of all new cars sold in China last year were electric, structurally reducing gasoline demand while high-speed electric trains replaced domestic flights.

The demand-side flexibility gives Beijing extraordinary leverage over oil prices at a moment when global buffers are thinning. The U.S. Strategic Petroleum Reserve has fallen to about 320 million barrels, a Reagan-era low, after 66 million barrels were drained since the conflict began. Analysts at TD Securities say $100 a barrel is plausible if physical shortages emerge, yet China's ability to stay quiet in the market could cap any rally.

How China's Energy System Absorbed the Shock

The pullback in oil purchasing has acted as a shock absorber for the global economy, keeping a lid on prices that surprised commodities traders. According to Kpler data, Beijing can comfortably suppress crude imports for another six months based on the rate it is drawing on its enormous stockpile. Even after that period, China would still hold close to 1.1 billion barrels of crude in storage — a mixture of refinery and commercial stocks and the country's strategic petroleum reserve.

Beijing may not want to drain stores too far. Inventories stood at 1.07 billion barrels early last year when the government announced a major stockpiling drive, a threshold that could send China back to the spot market to buy more oil.

The ability to dial down imports is the result of years of planning to reduce dependence on overseas oil. U.S. tech executives realized last year that China's artificial-intelligence players were not experiencing the same scramble to find power for data centers, thanks to the country's massive rollout of renewable-energy infrastructure. But it took a war to see China's new energy system in action.

Implications for Big Oil and Global Markets

The structural shift carries profound implications for oil suppliers. Traditionally, OPEC has used production quotas to move prices, with U.S. shale producers adding supply once crude went above roughly $65 a barrel. Demand for oil was assumed to be relatively inelastic.

"The demand side can now influence the market and that is quite scary for suppliers," said David Fishman, a principal at energy consulting firm the Lantau Group.

This is the second consecutive year that China's behavior has surprised the oil market. Some analysts were forecasting $50 oil toward the end of 2025 because of an oversupplied market, but a widely expected glut never materialized because Beijing was hoovering up crude to add to storage.

Now, the reverse dynamic is playing out. Brent crude traded at $85.23 a barrel Wednesday, up 3.84%, while WTI rose 4.25% to $82.63 after U.S.-Saudi joint strikes on Iran-backed targets in Iraq and Iran's ballistic missile attack on a Jordanian air base. Exxon Mobil has gained 24.1% year to date and Chevron 25.28%, as the Strait of Hormuz crisis rewarded energy investors betting on supply tightness.

June Goh, an analyst at Sparta Commodities, warned that a "violent repricing" is possible as the SPR buffer disappears. "Crude oil is fast losing its strategic petroleum reserve buffer, and a violent repricing up cannot be discounted until the market sees toned-down rhetoric from both parties," she said.

The decisions made in Beijing are bringing relief to other fossil-fuel-dependent countries, which must also be taking note of the breathing space China has given itself by electrifying its transport fleet and diversifying energy sources. Some Southeast Asian markets are already seeing surges in imports of electric vehicles and solar panels since the war began — an early indicator that other governments may follow Beijing's lead.

For oil suppliers, the question is no longer just about how much OPEC cuts or U.S. shale pumps. It is about when China decides to come back to the market — and whether its new energy system has permanently weakened the link between economic growth and oil demand.
