Diesel Prices Jump in Thailand after Government Cuts Fuel Subsidies

Diesel prices in Thailand surged sharply after the government moved to scale back fuel subsidies, reflecting mounting fiscal pressures and the global ripple effects of rising energy costs.

Authorities announced an increase of 2.80 baht per liter effective immediately, following a decision by the state Oil Fuel Fund committee to reduce subsidies for the diesel. The step marks a significant shift in pricing policy as Bangkok seeks to rebalance public spending while containing market distortions.

Under the revised structure, diesel (B7) prices in Bangkok rose to 50.54 baht per liter, up from 47.74 baht, while diesel (B20) increased to 45.54 baht from 42.74 baht. The adjustments apply to the capital and exclude local taxes.

The subsidy cuts were equally notable: support for B7 diesel was reduced from 20.71 baht to 18.10 baht per liter, while B20 subsidising fell from 22.22 baht to 19.61 baht.

In parallel, Thailand’s Ministry of Energy has launched a review of refining and marketing costs, aiming to determine the “true cost” of fuel. Officials suggest that current calculations may be inflated, contributing to higher prices at the pump.

Finance Minister Ekniti Nitithanprapas indicated that revised cost structures will be presented to the cabinet, potentially paving the way for future price adjustments.

The government is also exploring additional measures, including possible tax reductions and enhanced financial support for the fuel fund, which has been backed by a 150 billion baht ($4.6 billion) loan guarantee to stabilize energy prices.

However, rising fuel costs are already weighing on consumer sentiment. According to projections by the University of the Thai Chamber of Commerce, consumer spending could decline by 3.7% throughout the year, with a significant decline expected during the Thai New Year holiday.

The diesel price hike underscores how global oil market volatility, driven in part by geopolitical tensions, continues to filter into domestic economies. While gasoline prices remain unchanged for now, analysts warn that sustained pressure on energy markets could force further adjustments.
