China's Oil Demand Crash Is the Only Thing Keeping Global Prices Below $100

In late February 2026, the Strait of Hormuz — a waterway that normally carries about 20% of the world's oil and gas trade — was effectively closed after U.S. and Israeli strikes on Iran triggered Iranian retaliation against tanker traffic . The resulting supply disruption, estimated at 9–11 million barrels per day (b/d), is the largest in the history of the global oil market according to the International Energy Agency . But Brent crude has remained below $100, below its 2022 post-Ukraine peaks. The key reason: China's simultaneous and dramatic demand destruction.

The Supply Shock: A 9–11 Million b/d Hole

On February 28, 2026, the US and Israel launched strikes on Iran. Iran retaliated by effectively closing the Strait of Hormuz — attacking vessels and making insurance impossible or prohibitively expensive . After accounting for bypass capacities (pipelines, dark tankers, emergency IEA releases), the closure still removed roughly 9–11 million b/d from global supply . The IEA described the event as "the largest supply disruption in the history of the global oil market" .

China's Demand Destruction in Numbers

China, the world's largest crude importer, responded with a collapse in buying and refining:

• May 2026 crude imports plunged to around 6.7 million barrels per day (seaborne, per Kpler data), the lowest level in a decade — down about 3.5 million b/d year-on-year . Chinese customs data put the figure at 7.8 million b/d including pipeline supplies, still the lowest since October 2017 .
• May refinery runs fell to 53.72 million tons, down 9.1% year-on-year, the lowest since August 2022. State-owned refiners ran at an average rate of just 66.3% .
• PetroChina's Planning and Engineering Institute forecast China's 2026 total oil consumption will fall 4.9% to 753 million tons, citing both the shift to cleaner energy and the Iran conflict-driven price surge .

This was not solely a voluntary policy. The near-total halt of Persian Gulf shipments choked China's main crude supply route, forcing refiners to slash runs . Simultaneously, high fuel prices and China's accelerating electric-vehicle adoption — now over 50% of new car sales — structurally suppressed downstream demand .

The Paradoxical Price Cap

Despite a supply shortfall that Bloomberg calculated as "more than the oil consumption of the UK, France, Germany, Spain and Italy combined," Brent crude has not spiked catastrophically . China's pullback is a central reason:

• China cut its seaborne imports by roughly 3.5 million b/d year-on-year in May alone — the single largest discrete demand reduction anywhere in the world . J.P. Morgan analysts estimated that China's reduction accounted for approximately 74% of the overall decrease in global crude imports .
• The EIA noted that global oil demand is now consuming about 1 million fewer barrels per day on average than last year, sharply limiting price increases from the supply disruption .
• Analysts at Brookings and CNBC explicitly describe China's reduced buying as "a significant stabilizing factor" that helped keep oil benchmarks from spiking to catastrophic levels .

As a BNP Paribas research note summarized: "The decline in Chinese imports of oil is limiting upward pressure on global prices" .

How Long This Cushion Can Last

This demand-side buffer is inherently temporary. China has been drawing down its crude inventories — both from government strategic reserves and commercial storage — to sustain what refining it can. Semafor reported that while strategic petroleum reserves have actually increased by about 8 million barrels since the conflict began, refinery inventories fell by roughly 15 million barrels in May alone .

JPMorgan projects that approximately 3 million b/d of the reduction is temporary, with Chinese crude buying expected to gradually resume around August as demand from the chemical sector rebounds and China aims to replenish its strategic petroleum reserves .

The implication is clear: once China re-enters the market as a buyer, the full price impact of the Hormuz closure will become much harder to contain . As CNBC put it, analysts warn the current stability "won't last" . The Brookings Institution noted that while demand destruction has helped so far, the "massive shock" has yet to fully play out .
