The energy minister on Monday ordered a reduction in pump prices of 50 satang per litre for diesel and 30 satang for all kinds of petrol, effective from 5am Tuesday.
Auttapol Rerkpiboon said had ordered the board of the state Oil Fuel Fund to make the reduction to help reduce the cost of living and stimulate the grassroots economy.
The price of standard diesel will fall from 31.44 baht to 30.94 baht per litre. Retailers will decide whether to apply the cut to premium diesel.
On Monday retail petrol prices ranged from 27.89 to 49.84 baht per litre in Bangkok.
Prices are slightly higher in provinces outside the Bangkok area.
