Thailand Cuts Diesel Prices by THB1.20 Per Litre 

Thailand has lowered retail diesel prices by THB1.20 per litre starting April 21, 2026, following a decision by the Oil Fuel Fund Management Committee. The price reduction comes as global oil prices show signs of easing, allowing authorities to adjust subsidy levels and provide relief to consumers. The change has been implemented by major fuel retailers including PTT Oil and Retail Business and Bangchak Corporation.

Oil Fuel Fund Adjustment Drives Price Reduction

The diesel price cut is linked to revisions in the Oil Fuel Fund’s compensation and contribution rates. The committee stated that declining global crude oil prices allowed for reduced support spending while still maintaining price stability for consumers.

Diesel prices have fallen in response to softer international benchmarks, with global diesel trading lower compared to earlier in April. Petrol prices, however, have remained relatively stable, leading to no changes in retail pump prices for gasoline and gasohol products.

Retail Diesel Prices Drop Across Fuel Types

The new pricing structure has led to uniform reductions across major diesel categories in Thailand. Both B7 and B20 diesel variants saw a decrease of THB1.20 per litre.

Key Price Adjustments

• Diesel B7 reduced by THB1.20 per litre to THB41.70
• Diesel B20 reduced by THB1.20 per litre to THB34.70
• Super Power Diesel also reduced by THB1.20 per litre

These adjustments were implemented from 5 am on April 21, 2026, and apply across major fuel retailers nationwide.

Petrol and Gasohol Prices Remain Stable

While diesel prices were reduced, petrol and gasohol prices remained unchanged despite adjustments in Oil Fuel Fund rates. The committee modified collection and compensation rates for several fuel categories, but these changes did not translate into retail price adjustments.

Fund Rate Revisions

• Petrol collection reduced by THB0.56 per litre
• Gasohol 91 collection reduced by THB0.52 per litre
• Gasohol E20 compensation increased slightly
• Gasohol E85 collection reduced marginally

These revisions helped balance fund expenditure without impacting pump prices for gasoline users.

Oil Fuel Fund Liquidity Improves

The Oil Fuel Fund reported a significant reduction in daily expenditure due to easing global oil prices. Daily support payments have dropped sharply from over THB1.2 billion to approximately THB53.75 million.

Financial Stability Gains

• Lower global crude prices reduced subsidy burden
• Improved fund liquidity strengthens future price control capacity
• Better financial buffer for future energy shocks

The committee noted that the improved position will allow continued support for diesel consumers while maintaining long-term financial stability.

Consumer Impact and Market Outlook

The immediate diesel price reduction is expected to ease transportation and logistics costs across Thailand. However, continued fluctuations in global crude markets may influence future pricing decisions.

While diesel users benefit immediately, petrol consumers are likely to see stable prices unless global oil trends shift significantly in the coming weeks.
