China’s Oil Stockpiles Give It Unrivaled Leverage in Crisis

As global energy markets reel from the closure of the Strait of Hormuz following the U.S.-Israeli conflict with Iran, China has emerged in a uniquely advantageous position. With an estimated 1.4 billion barrels of strategic petroleum reserves — more than the entire International Energy Agency (IEA) membership combined — Beijing possesses a massive energy buffer that grants it significant geopolitical leverage while other nations scramble for supply.

A Two-Decade Strategy Comes to Fruition

China’s strategic petroleum reserve (SPR) program began in earnest in the early 2000s as Beijing recognized its growing vulnerability to maritime chokepoints. With oil import dependence exceeding 70%, energy security became a paramount national security concern. Over two decades, China constructed massive underground storage caverns and coastal tank farms while aggressively purchasing oil on global markets.

According to the National Security Journal, which cited U.S. Energy Information Administration data, China ended 2025 with nearly 1.4 billion barrels in strategic inventories. By contrast, the combined strategic reserves of all 32 IEA member countries stand at approximately 1.2 billion barrels, while the U.S. Strategic Petroleum Reserve holds roughly 384 million barrels — less than four days of global oil consumption.

“China has spent the past 20 years continuously building and filling its strategic petroleum reserves to prepare for moments like this,” Erica Downs, a senior research scholar at Columbia University’s Center on Global Energy Policy, told China Daily.

The Strait of Hormuz Crisis

The crisis began on February 28, 2026, when U.S. and Israeli strikes on Iran prompted Iran’s Islamic Revolutionary Guard Corps to declare the Strait of Hormuz closed. Tanker traffic dropped to near zero, blocking as much as 95% of traffic through the waterway, through which approximately 20% of global oil supply — over 14 million barrels per day — normally transits.

Brent crude surged past $100 per barrel and reached approximately $120 at its peak, triggering the largest energy supply disruption since the 1970s oil crises. Three-quarters of the barrels that normally transit the strait go to China, India, Japan, and South Korea.

China’s crude procurement in January and February 2026 surged 16% year-on-year to 96.93 million metric tons, further padding existing stockpiles during extreme global volatility. China imported 578 million tons of crude oil in 2025, a 4.4% year-on-year increase, with primary sources including Russia (17.4%), Saudi Arabia (14%), and Iraq (11.2%).

Structural Advantages Beyond Reserves

China’s energy resilience extends beyond its massive stockpiles. Crude oil accounted for only 18.2% of China’s total energy consumption in 2024, a figure that reflects the country’s aggressive push into renewable energy and electric vehicles.

OCBC analysts noted that China “may be less sensitive to a prolonged closure of the Strait of Hormuz than many of its Asian peers” due to “the rapid penetration of electric vehicles, increased substitution through coal-to-chemicals feedstock and a power generation system that is largely insulated from oil price fluctuations,” as reported by CNBC.

Lu Ruquan, president of the China National Petroleum Corp Economics and Technology Research Institute, told China Daily that a “robust energy framework of strategic diversification — combined with massive strategic reserves and expanding land-based supply routes — created a resiliency shield capable of enduring most significant maritime disruptions.”

Fu Fangjian, associate professor of finance at Singapore Management University, offered an even more optimistic assessment, stating that “China should be able to hold out for at least six months to a year.”

A Contrast in Strategic Preparedness

The disparity between China’s position and that of the United States is stark. The U.S. SPR has declined significantly from its peak of over 700 million barrels after years of emergency releases. The Biden administration’s historic release of 180 million barrels following the Ukraine invasion, combined with ongoing releases during the Iran crisis, has reduced America’s emergency buffer to its lowest level in decades.

The Trump administration announced plans to loan 53.3 million barrels from the SPR to major energy companies, including Exxon Mobil, Marathon Petroleum, and Trafigura, as reported by Reuters, and to release a total of 172 million barrels under a coordinated IEA agreement. Refilling the SPR would likely take years and cost tens of billions of dollars at current oil prices.

Geopolitical Implications

China’s massive oil reserves fundamentally reshape the geopolitical dynamics of the Hormuz crisis. While the U.S., Europe, and other Asian economies deplete their strategic reserves, Beijing can afford to wait. This position gives China significant leverage in diplomatic negotiations, including potential talks with Washington over Iran, trade, and regional security.

However, some analysts urge caution. Dr. John Calabrese of American University and the Middle East Institute wrote in The Diplomat that “despite sustained efforts to prioritize energy security across successive policy cycles, China remains exposed to external supply chains it does not control. The core problem is not simply import dependence, but reliance on maritime transit routes — particularly through the Strait of Hormuz — whose security ultimately lies beyond Beijing’s authority.”

What to Watch For

Several key questions will shape the coming months. First, how long can China maintain its reserve advantage if the Hormuz crisis extends beyond 12 months? Second, will Beijing use its energy leverage to extract concessions from Washington on trade, technology, or Taiwan? Third, the crisis may accelerate China’s already aggressive push into renewable energy, EVs, and grid-scale storage, further reducing long-term oil dependence.

For the United States, the crisis has exposed the consequences of a depleted SPR and raised urgent questions about strategic reserve policy. As the OilPrice.com analysis noted, China’s oil hoarding during a nearly year-long buying spree at relatively low prices is now paying off handsomely, positioning Beijing as a potential re-exporter to third markets if the supply crunch deepens.

The energy landscape has shifted, and China — with its full tanks and long-term strategy — appears to have placed itself on the winning side of this global crisis.
