The Center for Situation Administration (CSA) has approved upgrading the B7 fuel product to B10 and adding B20 for direct sale to the industrial and agricultural sectors. Diesel prices will be adjusted starting tomorrow, 18 March 2026, with a ceiling not exceeding 33 baht per liter. E20 gasoline prices will decrease by 0.79 baht per liter, while gasohol 95 prices will rise by 1 baht per liter.
On 17 March 2026 at the Government House, Mr. Phiphat Ratchakitprakarn, Deputy Prime Minister and Minister of Transport, said after the meeting of the Center for Situation Administration on the conflict in the Middle East that the refinery gate and oil depot prices would be announced, and the B7 fuel product would gradually be replaced by B10 with B20 added for the transport sector. However, B20 will not be sold at service stations but only wholesale to support industries such as transport, industry, and agriculture, because jobbers must bear transportation costs.
Energy Minister Mr. Atthapol Rerkpiboon stated that Thailand can confirm having 2 million barrels of crude oil from the Republic of Angola and 700,000 barrels from the United States, providing sufficient supply for 101 days. Refiners have been ordered to halt exports. Yesterday, discussions with operators confirmed that refineries will operate oil depots 24 hours a day for truck loading. Only dedicated oil trucks will be allowed to transport fuel. Although supply is adequate for normal use, panic buying has doubled demand. The Ministry has also requested cooperation from the Ministry of Interior, Ministry of Transport, Bangkok Metropolitan Administration, and traffic authorities to ease restrictions on fuel transport trucks, monitoring how much relief can be granted to alleviate queues at gas stations. The public is urged not to hoard fuel and to purchase normal amounts to restore normalcy quickly.
Regarding diesel prices, they have been capped at no more than 30 baht per liter. The plan is to raise the B7 price gradually to avoid impacting the public, with a ceiling of 33 baht per liter, noting that Malaysia has already adjusted prices to 32 baht. Tomorrow, diesel prices will rise by 0.50 baht per liter and will adjust progressively as needed, but not exceeding 33 baht per liter. Biofuel promotion will include raising the B5 standard to B7. Additionally, fuel products will be adjusted from B7 to B10, which will be 2 baht cheaper than B7, and B20 will be 5 baht cheaper than B7. These will be distributed to depots, and prices may decrease further if supplies increase.
E20 gasoline will have a price difference of more than 3 baht compared to E10. Today, the increase will be implemented, reflecting cost. Tomorrow, E10 or gasohol 95 prices will increase by 1 baht per liter, while E20 will be 0.79 baht cheaper, making it 5 baht cheaper than E10. The public is encouraged to use more E20.
Mr. Atthapol also addressed fuel hoarding, stating that discussions with the Ministry of Interior and Ministry of Commerce will include random inspections to ensure no stockpiling or excessive profiteering. Inspections have already been conducted to confirm that fuel supplies are sufficient and that fuel is being sold and used as expected.
