How China's electric vehicle boom is reducing the strategic importance of the Strait of Hormuz in global oil markets

While many view the Strait of Hormuz crisis as a major strategic vulnerability for China, given that it is the world's largest crude oil importer and heavily dependent on Gulf energy supplies, recent developments suggest Beijing now has a buffer that was absent during previous energy crises: the rapid expansion of electric vehicles, which has already begun to materially reduce oil demand.

Although around 45% to 50% of China's crude oil imports typically pass through the Strait of Hormuz, Beijing entered the current crisis with large strategic and commercial oil reserves, diversified sources of supply, and the ability to reduce refinery operating rates if necessary. More importantly, however, the country's accelerating transition to electric transportation has already eliminated demand for more than one million barrels of oil per day.

Electric vehicles eliminate demand for 1.35 million barrels per day

During the first half of 2026, electric vehicles in China displaced the equivalent of 34 million metric tons of oil consumption, or around 1.35 million barrels per day, representing more than 1% of total global oil demand.

That volume is equivalent to roughly 6% of China's annual crude oil imports in just six months. If the current pace continues through the end of the year, the total could approach 12% of annual imports.

This does not necessarily mean imports decline by the same amount, since oil demand is also driven by petrochemicals, refining margins, and broader economic activity. However, these figures represent oil that China simply no longer needs to purchase.

The reduction is also equivalent to around 10% of the total crude oil volume that passed through the Strait of Hormuz each day during 2025, reducing the impact of any future disruption to the waterway, even if it does not eliminate the risk entirely.

China started with the easiest vehicles to electrify

China first focused on electrifying buses because they operate on fixed routes and can be easily charged at depots before expanding into passenger vehicles.

During 2025:

• More than 13 million electric vehicles were sold.

• Electric vehicles accounted for around 55% of all new vehicle sales.

• The total number of electric vehicles on Chinese roads reached approximately 44 million.

According to the International Energy Agency, falling lithium iron phosphate (LFP) battery prices and rising domestic production have made around 70% of electric vehicles sold in China cheaper than the average conventional vehicle.

Passenger vehicles now account for roughly 54% of the total decline in oil consumption resulting from transport electrification.

Electric trucks begin cutting diesel demand

The next phase of China's transition is focused on heavy-duty trucks, which primarily rely on diesel fuel.

During the first half of 2026:

• Oil demand displaced by electric trucks increased by around 150% year over year.

• Heavy-duty electric trucks accounted for 28% of total sales during 2025, up from 13% in 2024.

• By December 2025, their market share had approached 50% of total sales.

China has concentrated on routes that are well suited for electric operation, including ports, mines, and industrial zones, relying on battery-swapping stations rather than attempting to electrify every segment of freight transport simultaneously.

Energy security, not just climate policy

China's electric vehicle strategy is often viewed primarily as a climate policy or an industrial development plan. However, the Strait of Hormuz crisis has highlighted another important objective: strengthening energy security.

Every gasoline- or diesel-powered vehicle locks in years of dependence on imported oil, while an electric vehicle runs on a power grid that is largely supplied by domestic energy sources.

Although China still relies partly on coal-fired electricity generation, power can also be produced from nuclear, hydroelectric, wind, and solar energy without requiring oil tankers to pass through the Strait of Hormuz.

During 2025 alone, China added around 500 gigawatts of renewable energy capacity, including:

• 370 gigawatts of solar power.

• 117 gigawatts of wind power.

This means an increasing share of China's transportation energy demand is being supplied by domestic renewable sources rather than imported oil or natural gas.

Lower demand reduces the strategic importance of oil chokepoints

China has not been immune to the crisis. The International Energy Agency estimates that its seaborne oil imports fell by around 3.6 million barrels per day between February and April. However, strategic reserves and reduced refinery utilization helped cushion the shock.

The IEA expects electric vehicle adoption to reduce Chinese oil demand by more than 4 million barrels per day by 2035, equivalent to more than one-quarter of the crude oil volumes that passed through the Strait of Hormuz during 2025.

This does not mean China will become independent of oil, but it will become significantly less exposed to the risks associated with maritime chokepoints, higher shipping and insurance costs, and crude oil price volatility.

Analysts conclude that while strategic reserves, pipelines, and diversified import sources can help manage supply disruptions in the short term, reducing demand itself is the only solution that permanently eliminates the need for an additional barrel of oil. That makes the transition to electric transportation one of China's most important long-term energy security strategies.
