The Oil Fund Management Committee approved a 0.75 baht per litre rise on all fuel types, effective 2 October (2026), because Middle East tensions pushed world prices up. Diesel for standard high-speed fuel now sells at 42.19 baht/litre, B20 at 37.19, Gasohol 95 at 40.69 and E20 at 35.69. Fund costs reached about 430 million baht a day. Review fuel-driven delivery, transport and equipment costs from 2 October and reprice quotes or surcharges where you can. The committee also asks users to use fuel only as needed.
