China's 'Teapot' Refineries Cushion Impact of Iran War on Oil Crisis

The ongoing conflict between Iran and the US-Israeli alliance has sent shockwaves through global oil markets, with Brent crude prices surging 5% to $106.16 per barrel on Thursday morning. Despite being heavily reliant on Iranian oil, China appears to have largely insulated itself from the crisis.

China's strategy involves utilizing 'teapot refineries,' small, privately owned oil refineries primarily based in Shandong province. These facilities have been importing discounted Iranian and Russian oil, accounting for one-quarter of China's processing capacity. This approach allows China to circumvent US sanctions and maintain a stable oil supply.

China's teapot refineries have been stockpiling oil reserves, providing a buffer against potential supply disruptions. According to Muyu Xu, a senior crude oil analyst at Kpler, China's seaborne crude imports in March stood at 10.19 million barrels per day (mbd), down from 11.51mbd in February but still in line with the 2025 average of 10.41mbd.

The US has previously imposed sanctions on some of these teapot refineries for importing Iranian oil. However, China's tolerance of this independent system has proved strategically useful, allowing the country to maintain a flexible buffer for bargain barrels during crises.

Experts note that while China's measures will not completely immunize the country from rising fuel prices, they do provide Beijing with more flexibility to survive a crisis compared with other nations. China's approach involves aggressive stockpiling, tolerating shadow networks, and keeping flexible buffers, demonstrating its preparedness for energy shocks.
