China's NDRC Raises Retail Gasoline 300 Yuan Per Tonne and Diesel 290 Yuan Per Tonne as Crude Surges 12% in a Week

China's National Development and Reform Commission raised the retail price cap for gasoline by 300 yuan per metric tonne and diesel by 290 yuan per metric tonne, effective July 18, 2026. The adjustment follows a 10-working-day crude price evaluation cycle that captured a 12% surge in international oil benchmarks. WTI crude settled at $82.44 per barrel on Friday's CME close, while ICE Brent settled at $88.10 per barrel, both per OilPrice.com market data.

How the NDRC Pricing Formula Works

China does not allow fuel prices to float freely with global oil markets. The NDRC periodically adjusts retail price caps based on a rolling average of international crude benchmarks, evaluating prices over a 10-working-day cycle. Analyst Liu Bingjuan noted that "the latest pricing cycle was marked by volatile gains in international crude oil prices amid renewed tensions in the Middle East."

Gasoline's 300-yuan-per-tonne increase was larger than diesel's 290-yuan-per-tonne rise, reflecting the different crude feedstocks and refining processes for each fuel type. Both adjustments apply at every licensed retail station in China's fuel distribution system. The regulated price caps update simultaneously nationwide, not on a regional rolling basis.

Calculating the Consumer Impact Per Litre

Converting the NDRC per-tonne adjustment to a per-litre figure requires applying a density factor. Gasoline has a density of approximately 730 to 750 kilograms per cubic metre, meaning one metric tonne covers roughly 1,333 to 1,370 litres. The 300-yuan-per-tonne increase, which OilPrice.com calculated as equivalent to approximately $44.29 per tonne, translates to roughly 0.22 yuan per litre at Chinese retail stations.

Diesel's 290-yuan-per-tonne rise, cited by OilPrice.com as approximately $42.82 per tonne, implies a similarly modest per-litre change. Diesel density averages approximately 840 kilograms per cubic metre, meaning one tonne covers roughly 1,190 litres. At that density, the 290-yuan adjustment works out to approximately 0.24 yuan per litre for diesel consumers.

Sinopec and PetroChina: State-Owned Subsidiaries Under the Cap

Sinopec Corporation, a subsidiary of the state-owned China Petrochemical Corporation, operates China's largest retail fuel distribution network. PetroChina, a subsidiary of China National Petroleum Corporation, operates a competing nationwide system. Neither company sets its own retail prices; both absorb the NDRC cap, which distinguishes China's downstream market from deregulated markets in North America and Europe.

The mechanism also applies to independent operators and regional distributors, meaning the July 18 adjustment cascades through every tier of the downstream supply chain simultaneously. Sinopec and PetroChina pass the cap change to their networks within days of the NDRC announcement. This creates a synchronized retail pricing environment across a market serving roughly 1.4 billion consumers.

Iran Tensions Drove the Benchmarks That Feed the Formula

The crude benchmarks feeding the NDRC formula spiked after US military strikes on Iranian infrastructure raised concerns about tanker flows through the Strait of Hormuz. Brent's 4.59% single-day gain on July 18 was part of a 12% weekly surge, the largest since April, per OilPrice.com reporting. Rigzone corroborated the sustained price elevation, noting WTI in the $82 range for the week of July 14-18.

WCS (Western Canadian Select) traded at $66.60 per barrel as of July 17, reflecting a $15.84-per-barrel discount to WTI, per OilPrice.com's two-day delayed price feed. Chinese refiners that purchase discounted Canadian heavy crude face a lower effective feedstock cost than the NDRC's Brent-anchored formula might indicate. Continued Hormuz disruptions are likely to sustain elevated Brent prices, keeping NDRC adjustment cycles active through the summer.
