China has suspended exports of refined petroleum products to all destinations outside Hong Kong and Macau, prompting immediate supply concerns and driving refined product premiums across the Asia-Pacific region to multi-year highs. Ahead of its Golden Week national holiday, Beijing withheld fresh monthly export clearances from state-run and mega-private refiners, while PetroChina moved to cancel scheduled October loadings for gasoline and aviation jet fuel.
The sudden withdrawal of fuel supplies from the world’s largest oil refining hub has sent regional product markets into sharp backwardation—a pricing structure where immediate deliveries command a steep premium over forward contracts. On October 1, Asian refining margins for gasoline surged past $50 per barrel over benchmark Brent crude, setting a fresh record. Concurrently, regional crack spreads for middle distillates jumped, with Asian diesel commanding premiums exceeding $70 to $75 per barrel above the crude feedstock as buyers scramble for replacement cargoes.
Key Takeaways
- Blanket Suspension for October: Chinese refiners have halted foreign dispatches of diesel, petrol, and jet fuel for October, restricting shipments solely to the special administrative regions of Hong Kong and Macau.
- Domestic Stockpiles Depleted: The halt is driven by thin domestic buffers. China’s commercial petrol stockpiles reached their lowest levels since 2011, and diesel inventories dropped to 2015 lows, with Kpler estimating a reserve shortfall of roughly 20 million barrels of diesel/gasoil and 9 million barrels of gasoline against pre-crisis baseline targets.
- Asian Refining Margins Surge: Gasoline refining margins in Asia climbed to an unprecedented peak of more than $50 a barrel over Brent crude, while diesel spreads surged to multi-month highs.
- Immediate Regional Fallout: Major fuel-importing hubs—led by Singapore, Indonesia, Malaysia, and Australia—face a severe supply crunch. Singapore’s light distillate inventories sit at five-year lows after Chinese inflows declined 62% over the first nine months of the year.
- Pre-Holiday Cargo Cancellations: PetroChina cancelled numerous committed export parcels for October, while Zhejiang Petroleum and Chemical (ZPC) scheduled zero product exports over the Golden Week holiday window.
- Uncertain Post-Holiday Resumption: Authorities have tied any potential resumption of export quotas after October 7 to the pace of domestic stock replenishment and refinery throughput recovery.
Central Question: Why Did China Halt Fuel Exports, and What Does It Mean for Asia?
Direct Answer: China halted refined fuel exports because its internal fuel reserves have hit multi-year lows following seasonal demand spikes, lower domestic refinery throughput, and earlier export surges in August. Facing an unstable global crude market shaped by Middle Eastern shipping disruptions and refinery outages elsewhere, Beijing chose national energy security over commercial export profits. For Asian economies, the sudden removal of Chinese volumes removes millions of barrels of monthly supply from an already tight market, forcing regional energy buyers to bid up local product prices and rely on extended import routes from India and the Middle East.

Root Causes: Why China Chose Energy Security Over Record Export Spreads
The suspension might appear counterintuitive from a purely commercial standpoint. International refining margins for diesel and gasoline have been running at historic highs, offering state and independent Chinese refiners attractive margins on seaborne sales.
However, Beijing’s regulatory apparatus prioritizes domestic market stability over trading profits:

1. Depleted Domestic Buffers
Following the initial tightening of fuel export quotas in March 2026 amid West Asian supply volatility, Beijing briefly loosened quotas in July, sparking an export surge in August where refined fuel shipments bounced back above pre-disruption levels and jet fuel exports hit historic highs.
This heavy outflow coincided with a seasonal pick-up in domestic road travel, agricultural harvesting, and industrial logistics. As domestic demand outpaced production, commercial fuel storage depots were drawn down to levels not seen in over a decade.
2. Reduced Domestic Refinery Throughput
China’s overall refinery throughput has contracted roughly 7% year-on-year. Higher delivered costs for imported crude, planned turnaround cycles across state-run Sinopec and PetroChina plants, and tighter environmental operating thresholds for independent “teapot” refineries in Shandong province capped overall fuel output, leaving insufficient spare supply to satisfy both domestic demand and foreign export commitments.
3. Hedging Geopolitical Supply Shocks
As the world’s largest importer of crude oil, China relies heavily on maritime trade corridors. With ongoing instability around the Middle East and attacks on global energy infrastructure keeping crude benchmarks volatile, policymakers determined that running low product inventories represented an unacceptable sovereign risk. Rebuilding the national fuel buffer acts as insurance against further crude supply interruptions.
Regional Fallout: Which Asian Markets Are Hit Hardest?
China’s decision to turn off the export valve hits Asia’s physical fuel trading hubs immediately:
REGIONAL EXPOSURE VECTORS
│
┌─────────────────────────────────┼─────────────────────────────────┐
▼ ▼ ▼
SINGAPORE TRADING HUB INDONESIA (PERTAMINA) AUSTRALIA & MALAYSIA
• Light distillate storage hits • Heavily dependent on blenders • Highly reliant on imported
5-year inventory low re-exporting from Singapore diesel & jet fuel for mining,
• 62% plunge in Chinese supply • Actively scouting replacement freight, and domestic aviation
dislocates marine bunker & blend cargoes from Mideast & India • Facing elevated freight premiums
1. Singapore’s Five-Year Stock Low
Singapore is Asia’s primary refining, pricing, and distribution center. Analytics data from Kpler reveals that Singapore received only 1.772 million metric tons (roughly 14.97 million barrels) of Chinese gasoline over the first nine months of the year—a 62% contraction compared to the same period in 2025.
With onshore light distillate stocks already sitting at their lowest levels in five years, the total absence of October Chinese cargoes leaves blending terminals short of blending components needed to meet regional product specifications.
2. The Domino Effect on Indonesia
Indonesia is Southeast Asia’s largest gasoline importer, sourcing the majority of its finished fuel from Singapore blenders who rely on Chinese feedstock.
State energy company Pertamina confirmed that it is closely monitoring China’s dynamic export stance while seeking alternative supplies from Indian, South Korean, and Middle Eastern refiners. However, replacing Chinese volumes requires competing for available cargoes, adding demurrage fees and longer transit times.
3. Australia’s Diesel Vulnerability
Having closed several domestic refineries over the past decade, Australia relies on imports for roughly 90% of its refined fuel requirements. Any sustained curtailment of Chinese middle distillates directly pressures regional supplies of ultra-low-sulfur diesel (ULSD), a critical input for heavy freight, haulage, and Western Australian iron ore mining complexes.
Market Dynamics: Record Crack Spreads and Steeper Backwardation
The trading response across commodity bourses in Singapore, London, and New York was swift:
CRACK SPREAD DISLOCATION

┌──────────────────────────────┴──────────────────────────────┐
▼ ▼
GASOLINE CRACK SPREAD DIESEL CRACK SPREAD
• Crossed **$50.00 / barrel over Brent** • Surged to **$70.00 – $75.00 / barrel**
• Breaks previous regional all-time records • Inter-month spreads in steep backwardation
• Severe shortage of high-octane blending stock • Immediate delivery carries massive premium
- Steepening Backwardation: In the derivatives and swaps market, October-November and November-December prompt spreads for gasoil and jet fuel widened into steep backwardation. Traders are willing to pay high spot premiums to secure prompt cargoes for immediate delivery, disincentivizing commercial stockpiling.
- Refiner Margins Outside China: Non-Chinese refiners across the region—notably in India (Reliance Industries, Nayara Energy) and South Korea (SK Energy, S-Oil)—stand to capture strong near-term margins. These refiners are adjusting distillation yields to maximize diesel and jet fuel production to serve the regional supply vacuum.
- Shipping Inefficiencies: Rerouting shipments from alternative suppliers in the Arabian Gulf or India’s west coast requires longer tanker voyages, tightening product tanker availability (MR and LR vessels) and raising charter rates across Asian waters.
What Could Happen Next?
- The Post-Golden Week Assessment (After October 7): Market participants are awaiting the end of China’s Golden Week holiday on October 7. The National Development and Reform Commission (NDRC) and Ministry of Commerce will review national inventory replenishment data to determine whether to release a limited supplementary batch of export quotas for late October or November.
- Government Stockpile Drawdown Pressures: If Asian diesel prices continue to climb, importing governments may consider releasing strategic petroleum product reserves or petitioning alternative refining exporters to step up shipments.
- Domestic Chinese Run Adjustments: If high international margins persist and domestic storage levels recover more quickly than anticipated, state-owned Chinese oil majors will likely push Beijing for quota allocations to capture profitable overseas sales before year-end.
Frequently Asked Questions (FAQs)
Why has China stopped exporting refined oil products?
China suspended refined fuel exports for October to rebuild its domestic stockpiles of gasoline, diesel, and jet fuel. Commercial petrol inventories have fallen to their lowest levels since 2011 and diesel stocks to 2015 lows, prompting Beijing to prioritize domestic energy security over export revenues amid global crude market uncertainty.
Which countries are most affected by China’s fuel export halt?
The suspension primarily affects fuel-importing nations across the Asia-Pacific region, including Singapore, Indonesia, Malaysia, Australia, and the Philippines. Singapore has seen a 62% year-on-year drop in Chinese gasoline imports, which in turn impacts re-exports to Indonesia.
What happened to Asian fuel prices and refining margins following the decision?
Expectations of reduced Chinese fuel supplies drove Asian gasoline refining margins to an all-time record of more than $50 a barrel over Brent crude. Diesel and jet fuel crack spreads also surged to multi-month highs, with monthly price spreads widening into steep backwardation.
Are all fuel shipments from China suspended?
China has suspended refined fuel exports to all international destinations except the special administrative regions of Hong Kong and Macau.
When might China resume exporting refined fuels?
Resumption will depend on how quickly domestic commercial inventories recover toward pre-crisis target levels (estimated at a 20-million-barrel gap for diesel and 9 million barrels for gasoline). Decisions regarding potential quota releases are expected after China’s Golden Week holiday concludes on October 7.
