The Energy Ministry is closely tracking developments in the conflict because further escalation could disrupt international energy markets and push crude prices even higher. Global prices have already registered substantial gains, and this Bangkok Business News report examines how Thailand is attempting to contain the impact on motorists and households while managing growing financial pressure on its fuel price support mechanism.
Global Crude Prices Surge
Oil benchmarks have risen sharply amid renewed geopolitical uncertainty. Brent crude increased from US$88.13 to US$94.65 per barrel, representing a gain of 7.4%.
US West Texas Intermediate climbed from US$83.38 to US$90.22 per barrel, an increase of 8.2%, while Dubai crude advanced from US$82.70 to US$88.75, rising 7.32%.
Energy officials expect international prices to remain highly volatile, with the possibility of further increases if fighting continues or concerns grow over disruptions to global energy supplies.
Fuel Fund Deficit Exceeds THB80 Billion
The rising oil market comes at a challenging time for Thailand’s Oil Fuel Fund, which recorded a deficit of approximately 80.47 billion baht as of August 30.
Despite the mounting shortfall, authorities intend to continue using the mechanism to help manage domestic fuel prices and reduce the immediate financial impact of higher global energy costs on consumers.
A refinery-gate diesel price reduction will also remain in effect until September 15, 2026, providing another layer of temporary relief while international crude prices remain under pressure.
Motorists Encouraged to Switch to E20
Authorities are encouraging motorists with compatible vehicles to consider E20, which is approximately 5 baht per liter cheaper than gasohol 91.
Thailand has sufficient ethanol production capacity to support increased consumption, while many cars and motorcycles can already operate on the fuel. Thirteen major vehicle brands have confirmed that compatible models can use E20.
Thailand Faces a Difficult Energy Balancing Act
The immediate challenge is maintaining affordable domestic fuel prices without allowing the Oil Fuel Fund’s financial position to deteriorate significantly further. A prolonged global oil rally could increase transportation and production costs, potentially creating wider price pressures throughout the economy.
Authorities will continue monitoring international oil markets and geopolitical developments while assessing existing price-support measures. The effectiveness of those measures could become increasingly important if crude prices remain elevated and the conflict continues to unsettle global energy markets.
