China Tapped 41 Million Barrels of Reserves in June to Outlast the Hormuz Supply Shock
IEA data shows Beijing drew 41 million barrels from inventories in June alone, covering the import gap without cutting refinery runs.
ICE Brent crude front-month was trading at $86.84 a barrel on Monday (2026-08-10), elevated but a long way from the triple-digit levels markets feared when the Iran conflict erupted. The Doomberg newsletter, writing on July 29 (2026-07-29), observed that China had "deftly weathered the storm" of the war's disruption to energy markets — a verdict the flow data now largely supports.6
Few countries looked more exposed when the conflict began. China depends on oil imports for roughly 13% to 14% of its total energy needs, according to The Economist, and nearly half its seaborne crude flows through the Strait of Hormuz. Analysts at OCBC argued in March (2026-03) that Beijing's multi-decade diversification program would leave China less exposed than its Asian neighbors to an extended strait closure. Subsequent months gave them the better of that argument.1,5
The import swing was severe. China's crude arrivals fell from around 11.6 million barrels per day in 2025 to 7.8 million barrels per day in May (2026-05), according to Foreign Policy. Seaborne receipts dropped more than 44% that month, according to Oilprice.com. Yet refiners kept running near normal rates. The gap came straight out of storage.2,5
The IEA estimated China pulled 41 million barrels from strategic and commercial inventories in June (2026-06) alone. "China has been putting a floor under prices," Rystad Energy's Janiv Shah said of the reserve buildup. Most estimates put China's strategic oil reserve at roughly 1.3 billion barrels, according to Foreign Policy. Analysts expected Beijing to draw that buffer at around 1 million barrels per day in subsequent months, a pace theoretically sustainable for years.5,2
Part of the resilience was structural. Two decades of pipeline construction across Russia and Central Asia mean Hormuz now handles only 40% to 50% of China's seaborne crude imports, according to Rush Doshi of the China Strategy Initiative, as cited by Oilprice.com. Those overland corridors ran uninterrupted through the worst months of the conflict.5
The Iran trade itself became complicated. Chinese imports of Iranian crude were projected to fall to around 556,000 barrels per day in July (2026-07), the lowest since early 2023, with 30 million to 34.5 million barrels sitting in floating storage with no buyer lined up, according to Oilprice.com. China normally absorbs around 90% of everything Iran exports, and Iranian tankers remained the only vessels still guaranteed passage through the strait. But insurance costs and sanctions uncertainty disrupted even that channel.5
Chinese refiners adapted by shopping elsewhere. Shenghong Petrochemical bought roughly 12 million barrels of Iraqi, Emirati and Saudi crude for July (2026-07) delivery once Gulf producers cut prices to shift barrels, according to Oilprice.com. The concessions gave Chinese buyers access to higher-quality crude at reduced cost.5
With the conflict winding down, Foreign Policy reported in mid-June (2026-06-16) that Beijing was already drawing lessons. China moved quickly toward post-war positioning. A meeting between Chinese Foreign Minister Wang Yi and his counterpart in New Delhi laid diplomatic groundwork for what analysts described to Oilprice.com as a push to secure long-term access to Iranian reserves through reconstruction investment.2,4
Longer term, Beijing is pushing non-fossil fuels to 25% of total energy consumption by 2030, up from roughly 22% when the conflict started, per Oilprice.com. EV adoption and renewable expansion have been trimming the oil intensity of Chinese economic growth for several years, partly explaining why domestic industrial activity held even as crude import volumes dropped sharply.5
But oil still supplies more than 18% of China's total energy, according to The Economist, and the underlying exposure persists. The 60-day ceasefire that news18.com cited in late June (2026-06-23) as critical for China's manufacturing economy remains fragile. If the strait closes again for any sustained period, even a 1.3-billion-barrel reserve has limits, and the overland pipelines that insulated Beijing this time carry their own geopolitical dependencies. The 30 million to 34.5 million barrels of Iranian crude sitting in floating storage as of early July (2026-07), with no cleared buyer in sight, will be the first market signal of whether the post-war energy relationship between Beijing and Tehran holds.1,3,5
