Officials said the key driver behind the adjustment was a sharp spike in global diesel (gas oil) prices, which jumped to around US$238 per barrel on March 27, compared with pre-conflict levels of roughly US$92–95 per barrel.
The committee noted that extreme volatility in global oil markets has forced it to closely monitor multiple factors, including international prices, regional benchmarks, the financial position of the Oil Fuel Fund, and the broader economic impact on consumers.
As a result, OFMCÂ convened an evening meeting between approximately 7pm and 8pm on March 30, before announcing the revised compensation rate shortly after.
The increase in diesel support has further strained the Oil Fuel Fund’s finances. Daily expenditure has risen by around 170 million baht, bringing total daily outflows to approximately 1.505 billion baht, up from 1.335 billion baht previously.
As of March 29, 2026, the fund remained deeply in deficit at 42.148 billion baht, comprising a 4.833-billion-baht shortfall in the oil account and 37.315 billion baht in the LPG account.
The latest adjustment underscores mounting pressure on Thailand’s energy pricing system as global oil markets remain volatile, with further price movements likely if international conditions persist.
