China's crude oil imports fell to their lowest level in more than eight years during May 2026 as supply disruptions stemming from the Iran conflict and continued constraints around the Strait of Hormuz weighed on purchases by the world's largest crude importer. According to customs data, crude imports declined to approximately 33 million metric tons during the month, equivalent to about 7.8 million barrels per day. This compares with an average import rate of around 11.6 million barrels per day in 2025.

The sharp decline was driven by a combination of reduced availability of Middle Eastern crude, higher oil prices, and weaker refining economics. Chinese refiners have increasingly relied on existing commercial inventories rather than competing aggressively for scarce cargoes in the international market. Analysts estimate that refiners have been drawing down stockpiles accumulated earlier in the year when discounted Russian and Iranian crude was more readily available.

The downturn in imports comes amid a broader slowdown in refining activity across China. Lower fuel demand, growing electric vehicle adoption, and government controls on domestic fuel prices have squeezed refinery margins, prompting both state-owned and independent refiners to curb processing rates. Chinese crude throughput had already fallen to multi-year lows earlier this year as refiners adjusted operations to changing market conditions.

China's reduced buying has had a significant impact on global oil markets. The decline in Chinese demand has helped ease supply pressures across Asia at a time when disruptions in the Middle East have constrained global crude availability. Analysts note that lower Chinese imports have effectively freed up cargoes for other Asian buyers, helping prevent a sharper spike in international oil prices.

Market participants remain focused on how long China can sustain lower import levels. While substantial inventories provide a temporary buffer, a prolonged drawdown could eventually force refiners back into the market, potentially increasing competition for crude supplies and adding upward pressure to oil prices.
