Thailand's Diesel Price Drops 2.40 Baht Today

Last Updated on September 16, 2026 by Jeff Tomas

CHIANG RAI – Drivers across Thailand are waking up to some much-needed relief at the pump for diesel starting today. The government has officially slashed the ex-refinery price of high-speed diesel by 2.40 baht per litre.

This welcome price drop takes effect on September 16 and will remain in place through October 31. The strategic move aims to protect consumers from the rising cost of living while securing the nation’s fuel supply.

The decision was recently approved by the Energy Policy Administration Committee (EPAC) and published in the Royal Gazette. Officials cited ongoing global market volatility and supply chain disruptions as the primary reasons behind this swift intervention.

By stepping in to lower refinery costs, the government hopes to ease the financial burden on the transport sector. Ultimately, this temporary relief is designed to keep everyday goods affordable for regular citizens.

Key Takeaways

Immediate Savings: The ex-refinery price of high-speed diesel drops by 2.40 baht per litre starting September 16.
Short-Term Relief: This government-mandated price reduction will remain in effect until October 31.
Economic Protection: The cut aims to shield the public from global fuel supply shortages and volatile crude oil markets.

The Middle East conflict continues to cause unpredictable swings in the global energy market. Tensions involving major international players have directly impacted the supply of crude oil and refined products. Because Thailand relies heavily on imported energy, these overseas disputes quickly translate to higher expenses for local drivers. The current price cut serves as a vital buffer against these unpredictable global shocks.

Specifically, the new discount applies to all three main grades of high-speed diesel sold domestically: B0, B7, and B20. This broad approach ensures that commercial trucks, public buses, and private vehicle owners can all benefit from the savings. The government is utilizing the Fuel Shortage Prevention and Remedy Act to enforce these changes. As a result, refineries must pass the savings down the line, eventually reaching the everyday consumer.

Looking Ahead at Thailand’s Energy Security

While the current price reduction offers temporary breathing room, the future of domestic diesel prices remains uncertain. The EPAC has not yet announced a long-term plan for when this measure expires at the end of October. However, officials are closely monitoring the global oil situation and domestic refining margins week by week. If geopolitical tensions in the Middle East worsen, we could potentially see further government interventions to stabilize prices.

For now, the local transport and logistics sector is celebrating these lower daily operating costs. Reduced fuel expenses mean delivery trucks and public transit companies can maintain their current rates. Shoppers may also feel the positive effects, as cheaper transport helps keep grocery and retail prices steady. Ultimately, this strategic move aims to keep the Thai economy moving forward despite international headwinds.
