China's crude oil imports have significantly declined in May 2026, averaging 7.8 million barrels per day. This drop represents a decrease of around 29-33% from the pre-war average of 11.6 million barrels per day. The loss of nearly 4 million barrels per day is comparable to the total oil output of Iraq, highlighting the profound impact of geopolitical events on global energy supplies.
What caused the decline in Chinese oil imports? The catalyst for this reduction is the Iran war, ignited by U.S.-Israeli military actions on February 28, 2026, which disrupted one of China's most vital and economical oil supply routes. By the end of 2025, Iran was supplying roughly 1.4 million barrels to China, accounting for up to 90% of its oil exports. With the pipeline now offline, China is facing significant challenges in maintaining its oil supply.
This structural damage goes beyond merely losing barrel counts. Analysts from Rystad Energy and Energy Aspects Ltd. have reported that a considerable portion of the lost demand might be permanent. Rystad Energy suggests that 200,000 to 600,000 barrels per day of transportation fuel demand may not recover in 2026, while Energy Aspects estimates a permanent loss of around 300,000 barrels per day, influenced by both the war and China's swift transition to electric vehicles.
Independent refineries in China, often referred to as "teapot" refineries, were particularly affected, as they relied heavily on discounted Iranian crude. With that source vanished, many of these smaller refineries have slashed production significantly, unable to switch to costlier alternatives.
To manage this crisis, China has withdrawn approximately 1 billion barrels from its strategic oil reserves, attempting to mitigate the shortage.
How is the Strait of Hormuz affected? The ongoing conflict has complicated the logistics through the Strait of Hormuz, a crucial passage that carries about one-fifth of global petroleum consumption daily. In an interesting development, Iran has allowed Bitcoin payments for tanker tolls in this region, charging around $1 per barrel. This marks a significant intersection between energy markets and cryptocurrency, raising concerns over potential volatility in both sectors.
What implications does this have for investors? The reduction in Chinese demand acts as a counterbalance to the supply disruptions, potentially dampening global oil prices despite typical market behaviors that would see prices rise during supply shortages. A consistent decrease of 3-4 million barrels per day in Chinese import volumes could create downward pressure on prices. Moreover, the forecasted permanent demand loss related to electric vehicle adoption indicates that the conflict accelerates China's shift towards a more sustainable energy model.
Looking ahead, China will eventually need to replenish its strategic oil reserves, which may result in sudden spikes in demand. However, replenishing these reserves at higher price points, without access to discounted Iranian crude, complicates the financial landscape, altering cost dynamics significantly.
