Key Highlights

  • China hit a domestic crude output record of 4.32 million barrels per day in 2025, the result of a seven-year state-directed investment drive.
  • The 15th Five-Year Plan targets maintenance at 4 million barrels per day through 2030, confirming this is a ceiling, not a launchpad.
  • December 2025 imports hit a single-month record of 13.18 million barrels per day, but the surge reflects strategic stockpiling rather than consumption growth.
  • EV penetration of new car sales has reached roughly 50%, and peak Chinese oil demand is now forecast by CNPC as early as 2025 at around 15.4 million barrels per day.
  • When China's stockpile build cycle ends, likely in the second half of 2026, a sharp pullback in import volumes poses material downside risk to global crude benchmarks.

A Record Built on Borrowed Time

China set an oil production record in 2025. It may never set another.

Domestic crude output reached 4.32 million barrels per day last year, the highest figure in the country's history and the result of a deliberate, seven-year government campaign to expand supply. State oil companies added the equivalent of a mid-sized OPEC producer's worth of capacity over the 14th Five-Year Plan period. Offshore Bohai Bay, the engine of that push, pumped 740,000 barrels per day, some 55% more than a decade earlier. On paper it looks like momentum. In reality it looks like a ceiling.

Both Wood Mackenzie and Rystad Energy project Chinese output broadly flat through 2028 before a gradual decline sets in. The 15th Five-Year Plan, released on 5 March, says it plainly: the target for 2026 to 2030 is to maintain output at 4 million barrels per day. Not grow it. Maintain it. Beijing is managing decline, not chasing records.

The geology tells the same story. Bohai Bay is a mature basin where reservoir pressure is falling and per-barrel costs are rising. The legacy onshore giants Daqing and Shengli are declining at 5 to 8% per annum. China's answer has been shale, and output from lacustrine formations reached 164,000 barrels per day in 2025, up 30% on the prior year. But Chinese shale is structurally different from the marine shale that powered the U.S. revolution. Formed in ancient lake beds, it is geologically fragmented and laterally discontinuous, characteristics that make it far harder and more expensive to complete at scale. The U.S. produces 9.7 million barrels per day from shale; China produces 164,000. That gap is not a timing issue. It is a geological one.

The Import Record Is Not What It Looks Like

While domestic output peaked, China's crude imports also hit a record of 11.55 million barrels per day on an annual average in 2025, up 4.4% year-on-year. December alone came in at 13.18 million barrels per day, the highest single month ever recorded. On first reading this looks like voracious demand. It is not.

The gap between what China imported and what its refineries processed tells the real story. Over January and February 2026, total supply averaged 16.41 million barrels per day while refinery throughput averaged 15.17 million barrels per day, implying a daily stock addition of 1.24 million barrels going straight into tanks rather than into fuel. From March 2025 onwards, independent estimates place stockpiling at close to 1 million barrels per day. Onshore crude inventories reached an estimated 1.2 billion barrels by January 2026. The government has announced 11 new storage sites with a combined capacity of 169 million barrels to be built across 2025 and 2026.

This is geopolitical insurance, not demand growth. That buffer will eventually reach its limits, and when it does, import volumes will revert sharply toward consumption levels. Markets that have priced the 2025 import pace into forward curves are exposed.

Demand is Peaking Too

Electric vehicles now account for roughly half of new car sales in China, a penetration rate that has no modern precedent in energy history. EVs alone displaced an estimated 3.5% of new gasoline demand in 2024, while compressed and liquified natural gas in road freight took out a further 2% of diesel consumption.

The institutions closest to the data have revised their demand forecasts sharply downward. CNPC's research arm now places peak Chinese oil demand at 15.4 million barrels per day, potentially as early as this year, against a prior estimate of 17 million barrels per day. Sinopec sees a ceiling of no more than 16 million barrels per day. The IEA has moved its peak estimate down by 3.5 million barrels per day in just a few years. A decade ago, analysts were modelling China reaching 20 million barrels per day by the early 2030s. That world no longer exists.

What It Means for Global Markets

The near-term risk is the stockpile unwind. When China's strategic petroleum reserve programme approaches saturation, likely in the second half of 2026, import demand could fall by 0.7 to 1 million barrels per day almost overnight relative to 2025 averages. If that coincides with OPEC+ continuing its phased supply restoration, global markets face a meaningful surplus impulse and Middle Eastern crude grades are most exposed.

Despite peaking demand, China will remain the world's largest crude importer through 2035 and beyond. Domestic production will decline faster than consumption in most credible models, meaning import dependency at 73% is structural and does not improve simply because demand peaks.

China's record output is real. So is the wall it just ran into. The record set in 2025 is, in all likelihood, the high-water mark, and the extraordinary import volumes that followed it are a hedge, not a harbinger.

 

 

 

 

 

FAQs

  1. Why is China's 2025 output considered a peak rather than a milestone?

The 15th Five-Year Plan targets maintenance at 4 million barrels per day through 2030 rather than further growth. Both Wood Mackenzie and Rystad project flat output before a gradual post-2028 decline, and legacy onshore fields are depleting at 5 to 8% per annum with no scalable replacement on the horizon.

  1. What drove the record December 2025 import figure?

Strategic stockpiling rather than consumption. Refineries processed 15.17 million barrels per day in early 2026 while total supply ran at 16.41 million barrels per day, implying a daily build of 1.24 million barrels into storage. The government is building a buffer against geopolitical supply risk, not responding to rising fuel demand.

  1. When will Chinese oil demand actually peak?

 CNPC puts the peak at 15.4 million barrels per day as early as 2025. Sinopec, the IEA, Wood Mackenzie, and Rystad all cluster their estimates between 15.2 and 15.8 million barrels per day over 2025 to 2030, down sharply from forecasts made just a few years ago that assumed China would approach 20 million barrels per day.

  1. Does peak demand mean China will import less oil?

 Not necessarily. Domestic production is set to decline faster than consumption, meaning the import gap may actually widen slightly through 2028 before stabilising. China will remain the world's largest crude importer well into the 2030s regardless of where demand peaks.
