Thailand’s diesel price will rise by Bt3.50 per litre at 05:00, on April 2, 2026, after the Oil Fuel Fund Committee reduced its subsidy, pushing the retail price of standard diesel to Bt44.24 per litre. Biodiesel B20 will also increase by Bt3.50, bringing its price to Bt39.24 per litre. The adjustment reflects a direct pass-through to consumers following lower compensation from the fund.

The decision was made at a committee meeting on April 1, 2026, where officials agreed to reduce financial support for diesel. This follows a previous increase on March 31, when diesel prices in Bangkok rose by Bt1.80 per litre to Bt40.74, marking the first time prices exceeded the 40-baht level in the current round of adjustments. The latest rise continues a rapid upward trend in domestic fuel costs over recent days.
Officials said the subsidy reduction was necessary to ease the financial burden on the Oil Fuel Fund, which has been supporting fuel prices amid market pressures. By lowering compensation rates for both standard diesel and B20, the committee allowed market pricing to play a larger role in determining pump prices. This has resulted in immediate increases for consumers and transport operators.
The higher diesel prices are expected to have a knock-on effect on logistics and transportation costs, potentially feeding into broader inflation. Businesses reliant on fuel, including freight and public transport sectors, may face increased operating expenses. Consumers could also see indirect impacts through higher prices for goods and services.
PTT and Bangchak also announced gasoline price adjustments. Prices will increase by 1.20 baht per liter: Gasohol 95 to 43.25 baht, Gasohol 91 to 42.88 baht, E20 to 38.25 baht, and E85 to 34.99 baht.
The Nation reported that additional changes to fuel pricing may occur depending on global oil market trends and the financial position of the Oil Fuel Fund. Policymakers are likely to monitor the economic impact of rising fuel costs while considering further adjustments to subsidies if needed.
