China’s crude oil imports saw a significant decline in April 2026, decreasing by 20% year-on-year to just 38.5 million metric tons. This marks the lowest import levels since July 2022, a time when parts of Shanghai were still experiencing COVID lockdowns. Unlike previous downturns caused by health crises, the current situation is driven by geopolitical factors, specifically the conflict in Iran, which has effectively closed the Strait of Hormuz. This waterway is a critical conduit for Chinese crude oil, typically responsible for handling between 40% to 55% of China's crude imports.
#What Impact Does Iran's Conflict Have on China's Oil Supply?
Iran has become a vital player in China's energy supply chain, providing about 12-13% of China’s crude imports in 2025. This translated to approximately 1.4 million barrels per day, mostly facilitated through complex networks designed to bypass sanctions. These networks included ship-to-ship transfers and relabeled cargoes, allowing Chinese companies to acquire Iranian oil at discounted rates.
However, with the situation changing, Chinese independent refineries, often referred to as “teapots,” are particularly affected. Concentrated in Shandong province, these smaller operators were the primary buyers of the discounted Iranian crude. Currently, they are facing urgent challenges in sourcing replacement barrels, and the prices they encounter are significantly higher than what they previously paid.
#How Is China Preparing for This Crisis?
Fortunately, China is not entirely unprepared for the current oil supply crisis. By the end of 2025, the country had amassed substantial oil reserves, estimated at around 1.4 billion barrels. In anticipation of the looming conflict in early 2026, Chinese importers increased their purchases by roughly 16% in January and February, effectively positioning themselves ahead of the situation.
This oil supply crisis is not only affecting imports; China’s fuel exports have also plummeted to levels not seen in a decade due to reduced refinery activity. With less crude oil arriving, the volume of refined products like diesel and gasoline that can be exported has declined, impacting fuel markets across Asia heavily reliant on Chinese exports.
#What Does This Mean for Investors?
China is a major consumer of global oil, using about one in seven barrels produced. Russia has positioned itself as China’s leading supplier in recent years, and the void left by Iranian oil creates opportunities for Russian producers to further penetrate the market. For investors interested in the energy sector, it is crucial to monitor the situation with the independent refineries in Shandong. These operators play a significant role in processing a notable portion of China’s crude supply. As refining margins are squeezed due to increased input costs stemming from the absence of cheaper Iranian feedstock, the financial dynamics within this segment may shift substantially.
