The Oil Fuel Fund Management Committee has resolved to approve a 0.75 baht per litre increase in the price of all fuels, except B20, E20 and E85, which will hold at their current prices, effective from 9 October 2026 onwards. The main reason is tension in the Middle East from attacks on ships in the Persian Gulf and the Strait of Hormuz, which immediately pushed up shipping costs, combined with China halting exports of refined oil products until Singapore stockpiles fell to a five-year low, and US crude inventories dropping by 3.2 million barrels. As a result, diesel prices in the Singapore market on 8 October 2026 surged above 177 US dollars per barrel, while gasoline jumped to nearly 156 US dollars per barrel. The situation has forced the Oil Fuel Fund to carry a compensation burden of about 363 million baht per day, making it necessary to adjust the fund's rates. In the diesel group, ordinary high-speed diesel B7 will have its compensation raised by 0.82 baht per litre to 2.82 baht per litre, with a retail price of 42.94 baht per litre. High-speed diesel B20 will have its compensation raised by 1.32 baht per litre to 7.57 baht per litre, but its retail price stays unchanged at 37.19 baht per litre. Premium diesel will be levied at 1.50 baht per litre. In the gasoline and gasohol group, gasoline will have its levy raised by 0.16 baht per litre to 1.88 baht per litre, with a retail price of 50.43 baht per litre. Gasohol 95 will have its compensation cut by 0.21 baht per litre to 4.63 baht per litre, with a retail price of 41.44 baht per litre. Gasohol 91 will have its compensation raised by 0.21 baht per litre to 4.63 baht per litre, with a retail price of 41.07 baht per litre. Gasohol E20 will have its compensation raised by 0.44 baht per litre to 8.29 baht per litre, with its retail price unchanged at 35.69 baht per litre, and gasohol E85 will have its compensation raised by 0.14 baht per litre to 2.66 baht per litre, with its retail price unchanged at 31.63 baht per litre.
Middle East attacks on ships in the Persian Gulf/Strait of Hormuz and China halting refined-oil exports tighten distillate supply, pushing diesel and heating-oil-linked prices higher.
