How China Turned from Big Oil’s Ideal Customer into a Nightmare

China’s control over its own oil consumption has exceeded all expectations. This will unsettle the executives of oil companies.

The Iran war has triggered one of the worst energy crises in history, and during this period, China—the largest customer in the crude oil market—reduced its imports by 40%. It turns out that China’s demand for oil is highly elastic and autonomous, proving that Beijing can now influence the future direction of oil prices.

Homayoun Falakshahi, head of crude analysis at Kpler, said, “We often joke privately that China is the OPEC of the demand side.”

Shortly after the Strait of Hormuz was closed, China began a “crash diet” in oil consumption. Data from the American Petroleum Institute shows that in 2025, China imported an average of 11.6 million barrels of crude oil per day. By June this year, imports had plummeted to around 7 million barrels per day.

Such a large-scale reduction in imports by a single country is unprecedented, even during severe economic recessions. In the second quarter of this year, China’s economy grew by 4.3%. While this is a slowdown from the first quarter, it is by no means enough to cause a cliff-like drop in energy consumption.

China’s decline in oil procurement has acted as a shock absorber for the global economy, not only curbing oil price increases but also stunning commodity traders. They are now trying to figure out how long China can remain silent in the market.

This is a crucial question because global oil inventories are being rapidly depleted, and countries have few tools left to withstand the shock of high energy prices. Once a heavyweight buyer like China returns to the market, oil prices will inevitably rise.

According to Kpler’s data, given the current pace of drawing down massive oil reserves, the Chinese government could comfortably suppress crude imports for another six months. Even after that, China would still have nearly 1.1 billion barrels of crude oil in reserve—this includes refinery inventories, commercial stocks, and the national strategic petroleum reserve.

However, Beijing may not want to excessively deplete its reserves. Last year, when the Chinese government announced a major reserve plan, oil inventory levels stood at 1.07 billion barrels. This could be a red line; once breached, China might return to the spot market to buy aggressively.

In addition to tapping emergency reserves, Beijing restricted refinery utilization rates and banned fuel exports shortly after the Iran war broke out. This meant refineries did not need to import as much oil, and domestic supply remained ample.

Moreover, shifts in consumer behavior have weakened demand for petroleum-based fuels. More people are choosing to drive electric vehicles instead of gasoline cars, or taking high-speed rail instead of domestic flights.

China’s ability to cut imports so confidently stems from years of government planning to reduce dependence on overseas oil. There are clear signs the country’s energy system has transformed: in 2025, over half of new cars sold in China were electric vehicles. Last year, executives at U.S. tech giants realized that thanks to China’s large-scale deployment of renewable energy infrastructure, Chinese AI companies were not scrambling for power for data centers like their American counterparts.

Yet it wasn’t until a war broke out that the true power of China’s new energy system became clear. The impact on the oil market is enormous. Traditionally, the Organization of the Petroleum Exporting Countries (OPEC) regulated oil prices through production quotas; once prices exceeded about $65 per barrel, U.S. shale producers would ramp up supply. In the past, oil demand was considered relatively inelastic.

David Fishman, head of Lantau Group, an energy consulting firm, said, “The demand side can now influence the market. That’s quite scary for suppliers.”

This marks the second consecutive year that Beijing’s moves have unexpectedly impacted oil prices. Some analysts predicted that oversupply would drive oil prices down to $50 per barrel by the end of 2025. However, the anticipated glut never materialized because Beijing was aggressively buying crude to expand its reserves.

Now, Beijing’s decisions are giving other countries reliant on fossil fuel imports a breather. These nations surely have noticed that China has bought itself breathing room through transportation electrification and diversified energy sources.

This kind of public relations success is something climate organizations—trying to persuade governments to shift to new energy systems—have dreamed of but never achieved. Since the war began, imports of electric vehicles and solar panels have surged in some markets, particularly in Southeast Asia. This could be an early signal that other governments are beginning to emulate China’s approach. For oil suppliers, this is undoubtedly a case of adding insult to injury.
