CHIANG RAI – Drivers in Thailand will pay more at the pump starting today. The national oil fund committee approved a price hike of 0.75 baht per liter for all fuel types. This change took effect early on October 2, 2026. Global energy concerns, specifically rising tensions in the Middle East, are driving these sudden increases.

These geopolitical issues have created major worries for the global oil supply chain. In the Singapore market, diesel prices recently climbed above 179 US dollars per barrel. Meanwhile, gasoline prices have surpassed 157 US dollars per barrel.

As a result, the Thai government has been paying about 430.14 million baht daily to cover local costs. Officials adjusted the rates to reduce this heavy financial burden and keep the state fund stable amid unpredictable global energy markets.

Key Takeaways:

All gas types increased by a flat rate of 0.75 baht per liter on October 2.
Standard diesel now costs 42.19 baht per liter at retail stations.
The price hike stems from Middle East tensions pushing global oil prices much higher.

The sudden price jump reflects how closely local fuel costs tie to world events. For weeks, experts have watched the Middle East conflict threaten essential shipping routes. When international oil gets expensive, local authorities must eventually pass those costs to consumers. Thailand relies heavily on imported oil to keep its daily economy moving. Therefore, managing the state oil fund carefully is vital to prevent extreme economic shocks.
