Global Diesel Supply Tightens as China Halts Fuel Exports

2 October 2026

Executive Summary

Pressure on global refined-fuel markets has intensified after Chinese refiners suspended most October exports of diesel, gasoline and jet fuel while Russia extended restrictions on diesel exports.

Chinese refiners are prioritising domestic fuel security, with exports currently restricted largely to Hong Kong and Macau.

The duration of China’s restrictions remains uncertain.

Russia has meanwhile extended its diesel export restrictions through October, further tightening an already constrained international refined-fuel market.

The combined pressure comes at a difficult time for global transport and industry.

Brent crude was trading around $102.60 per barrel early this morning, but the more important corporate risk increasingly lies in refined-product availability rather than crude oil alone.

The emerging problem is not simply the price of oil — it is whether enough diesel, jet fuel and other refined products are available where businesses need them.

UK Impact

Diesel is embedded throughout the UK economy.

Higher prices or constrained availability can affect:

• Road haulage.
• Agriculture.
• Construction.
• Warehousing.
• Emergency generators.
• Shipping.
• Manufacturing.
• Distribution fleets.
• Heavy equipment.
• Aviation through jet-fuel markets.

Higher transport costs can therefore spread rapidly through supply chains.

Even businesses that do not purchase significant quantities of fuel directly may experience higher supplier and freight charges.

Global Impact

China possesses enormous refining capacity and can provide important additional supply when international refined-product markets tighten.

Removing Chinese exports while Russian exports are constrained reduces that flexibility.

The United States has also been discussing the possible release of European emergency diesel inventories with Germany, France and other European countries.

Global diesel inventories are already tight following refinery disruption associated with the Middle East conflict and disruption to Russian energy infrastructure.

This creates a classic second-order supply-chain risk:

Crude oil can be available while the refined fuel required to move goods remains scarce.

Our View

Businesses should now separate crude-oil risk from refined-fuel risk.

Companies should ask:

• How much diesel exposure exists in our logistics contracts?
• Are fuel surcharges capped?
• Can hauliers pass increases directly through?
• Are transport quotations still valid?
• How long are freight rates fixed?
• Do suppliers depend upon diesel generators?
• Are construction projects exposed?
• Could agricultural suppliers face higher costs?
• Are emergency generators adequately fuelled?
• Do critical sites have minimum fuel stocks?
• Are alternative suppliers available?
• Could rail substitute for road freight?
• Could higher jet-fuel costs affect air freight?
• Are inventories sufficient to absorb delivery delays?
• Are customers contractually protected against fuel surcharges?

Businesses should also avoid using crude-oil prices alone as their energy-risk indicator.

The commodity can exist while the product businesses actually consume becomes scarce.
