Diesel prices in Thailand will rise again on April 3 after the Oil Fuel Fund committee reduced subsidies for a second consecutive day, pushing retail costs higher and triggering increases in public transport fares. The subsidy for diesel has been cut by 3.51 baht per litre to 14.27 baht per litre, resulting in pump prices rising by 3.50 baht per litre to 47.74 baht per litre. Biodiesel B20 will also see a similar increase, with prices climbing by 3.50 baht per litre to 42.74 baht per litre following a subsidy reduction of 3.48 baht per litre.

The latest adjustment follows an earlier subsidy reduction, marking two consecutive days of price hikes. Authorities said the move reflects ongoing pressure on the Oil Fuel Fund and the need to gradually reduce financial support for fuel pricing. The changes come at a sensitive time, just ahead of the Songkran Festival, when travel demand typically surges across the country.
In response to rising fuel costs, the Transport Department has approved fare increases for public transport operators. Bus fares will rise by 5 satang per kilometre, while passenger van fares will increase by 2 baht per 100 kilometres. Mr Thitipat Thaijongrak, the department’s spokesperson, said the adjustment was necessary as fares had not been revised for a long time despite increasing operational costs.
He added that without the fare increase, operators could be forced to reduce services or halt freight transport due to declining profitability. This would be particularly disruptive during the upcoming holiday period, when maintaining transport capacity is essential. The fare changes are intended to ensure service continuity and support operators facing higher fuel expenses.
The Thai NewsRoom reported that further adjustments to fuel subsidies and transport fares may be considered if global energy prices remain volatile. Authorities are expected to continue monitoring the financial status of the Oil Fuel Fund while balancing the impact on consumers and businesses. The immediate focus remains on maintaining stable transport services during the Songkran travel period.
