Energy Minister Aeknat revealed that the Energy Policy Committee (EPC) has resolved to reduce diesel refinery prices in two phases: a 5 baht per liter reduction starting tomorrow, 24 April 2026, followed by an additional 3 baht cut beginning 10 May. This aims to alleviate the public's financial burden while maintaining the country's energy stability.
23 April 2026 GMT+7 Mr. Aeknat Promphan, Minister of Energy, disclosed following the Energy Policy Committee (EPC) meeting that the EPC approved a reduction in refinery prices for high-speed diesel to mitigate the impact of living costs on the public and to safeguard the stability of the country's energy prices during the ongoing energy crisis. The committee decided to revoke the EPC announcement dated 8 April 2026 and set new refinery price reductions for high-speed diesel B0, B10, and B20 in two periods: from 24 April 2026 to 9 May 2026, a reduction of 5.00 baht per liter; and from 10 May 2026 to 19 May 2026, a further reduction of 3.00 baht per liter.
This measure was considered after closely monitoring oil prices and refining costs. Following the EPC’s decision on 7 April 2026 to reduce refinery prices for high-speed diesel by 2.00 baht per liter, effective from 9 April 2026, to help ease living expenses and lower retail fuel prices for the public.
An analysis of refining costs by oil refineries from 1 to 16 April 2026 revealed that, considering additional costs due to the abnormal energy crisis situation—such as Crude Premium, Product Premium, War Risk Premium, transportation, and insurance—there remains an excess refinery margin of 3.43 baht per liter. Therefore, it was deemed appropriate to use this excess margin as a price discount at the refinery level for high-speed diesel to benefit the public adequately, while also ensuring the continuity of refinery business operations.
Additionally, relevant agencies have improved the reporting forms from refineries to a higher standard, enabling more complete and accurate breakdowns of cost components. This will support transparent, fair, and realistic oversight of fuel price structures.
The Minister of Energy also stated that "This measure aims to reduce the public's energy expenses by balancing the cost of living with the country's energy stability. It seeks to provide tangible relief to the people while continuing refinery price reduction measures for high-speed diesel. The EPC will draft and announce the second edition of the refinery price reduction for high-speed diesel, which will be published in the Royal Gazette and take immediate effect from 24 April 2026 onward."
