China Oil Demand and Oil Prices

Why China matters so much

China's own oil output, about 4.4 million b/d in 2025 according to the IEA, covers only about a quarter of what it uses, so it must import most of its crude. It overtook the United States as the largest oil importer in 2013, and in recent years its crude imports have run at around 11 million b/d, according to Chinese customs data. That makes Chinese buying the single largest source of demand for seaborne crude priced off Brent and Dubai. When China's imports slow, exporters from Saudi Arabia to Brazil must find other buyers, often at lower prices.

Imports and suppliers

China buys from a wide range of suppliers. Russia, Saudi Arabia and Iraq have been the largest in recent years, followed by Malaysia, which is widely seen as a transfer point for Iranian crude, and Brazil, Oman and the UAE. Data firm Vortexa estimates that about one-third of China's oil arrived through the Strait of Hormuz in 2025. The EIA says China, India, Japan and South Korea together took 69% of the crude and condensate shipped through the strait in 2024.

The 2026 war changed the import mix. In March 2026 China received 1.8 million b/d of Russian crude, according to the IEA, and US sanctions waivers for Russian and Iranian cargoes already at sea allowed Chinese refiners to absorb about 14 million barrels of Russian oil that had been sitting on tankers.

Stockpiling: China's buffer

China has built large crude stocks in strategic reserves and commercial tanks. Vortexa estimated state and industry stocks at around one billion barrels in March 2026. China does not publish regular inventory data, so analysts infer stock changes by subtracting refinery runs from production plus imports. The IEA estimated that China added 1.3 million b/d to its crude stocks in March 2026, as cargoes bought before the war arrived, and that Chinese crude accounted for almost 90% of non-OECD stock builds in February.

Stockpiling makes Chinese import data a poor guide to actual consumption. Strong imports in a period of low prices often reflect reserve filling, not demand. In 2026 the government was reluctant to release strategic reserves, the IEA reported, but allowed state companies to draw on commercial reserves held for the government.

Refiners and teapots

China's refining industry is dominated by the state companies Sinopec and PetroChina, plus large private integrated complexes. A large group of independent refiners, nicknamed teapots, operates mainly in Shandong province. They buy crude under government import quotas and are the main buyers of discounted Iranian, Russian and Venezuelan barrels.

In 2026 Beijing used these levers actively. According to the IEA's April 2026 report, the government issued an extra 55 million tonnes (about 405 million barrels) of crude import quotas to independent refiners, linked to conditions on maintaining runs. It also blocked refined product exports beyond Hong Kong and Macao, and Sinopec cut runs by about 600,000 b/d in March. The export ban tightened Asian product markets and contributed to the jump in diesel crack spreads.

EVs, trucks and peak gasoline

China's road fuel demand is changing faster than in any other large economy. Electric cars now account for a large share of new car sales, which is eroding gasoline demand growth. In freight, the IEA notes rapid penetration of battery-electric and natural gas-powered (LNG) trucks, which gives some flexibility between diesel and other fuels. The IEA describes the oil intensity of the Chinese economy as low and falling. Growth has shifted to petrochemical feedstocks: naphtha accounted for 270,000 b/d of demand growth in early 2026, according to the IEA. For oil prices, this means Chinese demand is likely to grow more slowly than in the past and depend more on the chemical cycle than on driving.

How Chinese data moves the oil price

Import figures often move prices on the day of release, but traders compare them with refinery runs to separate stockpiling from consumption. A strong import number combined with flat runs suggests stockbuilding, which may not last. Weak runs combined with high product exports suggest weak domestic demand. Policy signals, such as new import quotas or changes in product export permits, can matter as much as the data.
