Prices of fuel sold along motorways and expressways have been deregulated since 2016, as has the price of heating oil and premium petrol regardless of point of sale.
Regular petrol and diesel sold at all other service stations have been subject to price caps determined every two weeks.
Fuel providers, foremost among them Slovenia's largest energy company Petrol, have long complained that the state-imposed margins are too thin.
Successive governments have argued that price caps are necessary due to insufficient competition, as the market is controlled by three major players: Petrol, Austria's OMV and Hungary's MOL.
The government now says that "given suitable measures and activities to increase competitiveness on the oil derivatives market, new discount providers may enter the market, in particular in the parking lots of shopping centres."
Under that assumption, margins and hence prices would not rise. "Within five years after deregulation… they would reach the level of margins comparable to margins in other EU member states.
