Thailand’s Fuel Fund Executive Committee has approved a 0.60 baht per litre increase in retail prices for B7 diesel, E10 gasohol 95 and 91, and petrol. The new rates took effect on Wednesday, October 21, 2026, after a decision announced on October 20.
Under the new structure, B7 diesel retails at 43.54 baht per litre and petrol at 51.03 baht per litre. Gasohol 95 rose to 42.04 baht per litre and gasohol 91 to 41.67 baht per litre.
Global Price Drivers Cited
The committee linked the increase mainly to Houthi attacks on energy infrastructure in Saudi Arabia and on shipping in the Persian Gulf. Ships rerouting around Africa raised freight costs, which reduced oil imports into Singapore and tightened supply. A larger-than-expected 3.2 million barrel drop in US crude inventories added further upward pressure.
On October 20, 2026, Singapore-market diesel traded at around US178 per barrel and petrol at around US136 per barrel. As a result, the Oil Fuel Fund was facing subsidy costs of about 229 million baht a day. The committee said it needed to adjust the fund’s levy and subsidy mechanisms to preserve liquidity for managing domestic energy prices.
Levy And Subsidy Changes
For diesel, the subsidy on regular B7 high-speed diesel rose by 0.69 baht to 2.41 baht per litre. The B20 subsidy rose by 1.08 baht to 7.63 baht per litre, leaving its retail price unchanged. Premium diesel now carries a levy of 1.50 baht per litre.
For petrol and gasohol, the petrol levy fell by 0.29 baht to 6.61 baht per litre. Subsidies for gasohol 95 and 91 each rose by 0.22 baht to 0.28 baht per litre. The E20 subsidy rose by 0.69 baht to 4.91 baht per litre and the E85 subsidy by 0.22 baht to 1.62 baht per litre, leaving both retail prices unchanged.
PTT Oil and Retail Business, which operates PTT Station, and Bangchak Corporation applied the 0.60 baht increase from 5am on October 21. E20 gasohol and B20 diesel prices were unchanged at both chains.
Follow-Up Adjustment And Fund Position
On October 21, the Oil Fuel Fund Board announced further changes to contributions and subsidies, effective October 22, while retail prices stayed the same. The B7 diesel subsidy rose from 2.41 baht to 3.20 baht per litre, and the B20 subsidy from 7.63 baht to 8.31 baht per litre. The gasoline contribution rose from 6.61 baht to 6.70 baht per litre, while gasohol subsidies were reduced.
The fund’s accumulated deficit has reportedly passed 100 billion baht because of global oil price volatility. The Ministry of Energy is reportedly preparing five measures to manage prices and support the fund. These include asking the Ministry of Finance to cut the oil excise tax by 1 to 2 baht per litre and promoting E20 gasohol and B20 diesel. Publicly available details on how and when these measures would be adopted remain limited.
The Oil Fuel Fund asked all sectors to use fuel efficiently and only as necessary, saying global oil prices are expected to remain volatile.
