China’s electric vehicles begin reshaping global oil demand

Electrification reaches the oil market

Electric vehicles are beginning to weaken a relationship that has shaped energy forecasts for more than a century: the link between a growing vehicle fleet and rising oil consumption. More cars, buses and trucks historically meant greater demand for gasoline and diesel. China’s accelerating transport electrification now shows that vehicle numbers can grow without producing a corresponding increase in road-fuel use.

According to Katadata, electric vehicles in China displaced about 34 million tonnes of oil equivalent during the first half of 2026. That volume was equivalent to approximately 1.35 million barrels a day and more than 1% of total global oil demand. The displacement recorded in six months also represented around 6% of China’s annual oil imports. If the trend continues through the end of the year, the displaced consumption could equal 12% of the country’s annual imports.

The figures give electric mobility significance beyond vehicle sales and emissions policy. For China, replacing petroleum-powered vehicles reduces exposure to international oil-price volatility and potential supply disruptions. For crude producers, refiners and fuel traders, it means that road transport can no longer be assumed to provide the same automatic support for demand as the vehicle fleet expands.

Passenger cars lead as trucks accelerate

China’s transition developed in stages. Buses moved first because their fixed routes, high utilization and regular return to depots made charging comparatively straightforward. Passenger vehicles followed as battery prices fell, technology improved and competition among domestic manufacturers, including BYD, made electric models more affordable. Passenger cars now account for about 54% of the oil consumption displaced by electric vehicles in China.

The next phase is heavy commercial transport, a segment long considered difficult to electrify because of range, payload and charging requirements. Katadata reported that oil displacement from electric semi-trucks increased by about 150% in the first half of 2026 compared with the same period a year earlier. Predictable logistics routes, depot charging and battery-swapping technology are helping electric drivetrains enter one of road transport’s largest fuel-consuming segments.

This development matters because heavy trucks operate intensively and consume substantially more fuel per vehicle than passenger cars. Their electrification could therefore affect diesel demand even before electric trucks represent a dominant share of the commercial fleet. It also creates new competitive considerations for truck manufacturers, battery suppliers, charging operators and logistics companies assessing fleet costs and infrastructure needs.

Oil remains essential, but forecasts must change

The shift does not imply an imminent end to oil consumption. Petrochemicals, aviation, shipping and other industries will continue to require large volumes. The more immediate consequence is that growth in global oil demand may no longer follow its historical pattern, because road transport has been one of its principal sources of expansion. Forecasts based mainly on rising vehicle ownership risk overstating future gasoline and diesel consumption where electrification advances quickly.

Indonesia faces the change from both sides of the energy market. The country imports crude oil, refined fuels and liquefied petroleum gas to meet domestic requirements, so greater EV adoption could reduce pressure on energy imports and improve the energy trade balance over time. At the same time, Indonesia is one of the world’s largest nickel producers and an important potential supplier to the EV battery industry.

Investment in mineral processing could support battery production, electric vehicles, energy-storage systems and related manufacturing. However, the opportunity depends on industrial execution as well as mineral availability. China’s experience indicates that electrification becomes material to oil markets when it moves beyond passenger cars into high-use fleets and heavy transport. The emerging turning point is not the disappearance of oil, but the weakening of the assumption that economic and vehicle growth must always produce higher oil consumption.
