CHIANG RAI – Drivers across Thailand need to dig a little deeper into their wallets this week. Gas and diesel prices have just gone up by 0.85 baht per litre across the country. The change took effect early Wednesday morning and impacts most standard fuels that everyday commuters rely on.
The sudden price hike was announced by major energy companies, including PTT and Bangchak. While premium fuel options remain unchanged for now, the cost of regular gasoline, gasohol, and standard diesel all saw the 85-satang bump. This move has left many motorists rushing to fill their tanks before the new rates kicked in.
Key Takeaways
- Gas and diesel prices in Thailand increased by 0.85 baht per litre on August 19, 2026.
- The price hike is tied to rising global oil costs and an empty state fuel fund.
- Officials are working on plans to help farmers and low-income drivers handle the extra costs.
Why Are Gas Prices Rising in Thailand?
The main reason for the higher cost is a sudden spike in global oil prices. Conflicts in the Middle East have caused crude oil rates to jump around the world. Because Thailand buys a lot of its refined oil based on Singapore market prices, these international problems directly hit local gas stations. When the cost of oil goes up overseas, the costs naturally trickle down to Thai drivers.
At the same time, the Thai government is running out of money to keep prices low. For months, the Oil Fuel Fund has been spending billions of baht to subsidize gas and diesel. However, this fund is now facing a massive debt that is approaching a dangerous level. Officials had to cut these subsidies to protect the state fund from going completely bankrupt.
How Is Thailand Dealing With the Higher Costs?
The government knows that higher fuel costs make life harder for everyday people and hurt local businesses. To fix this, leaders are looking at new ways to help the most vulnerable groups. They plan to offer targeted support to farmers, truck drivers, and small business owners who rely heavily on cheap diesel. By focusing help on those who need it most, the state hopes to prevent food and delivery prices from skyrocketing.
Meanwhile, energy officials are strongly urging the public to use fuel more carefully. They suggest carpooling, using public transit, and combining trips to save money on gas. Even with the recent 0.85 baht increase, fuel prices in Thailand are still lower than in many nearby countries. This is largely due to careful government planning and ongoing price limits.
