The government will review prices of fuel products on a monthly basis as of January 1, 2013, Ministry of Energy and Mineral Resources Secretary General Farouk Hiyari said Monday.
Since petroleum product prices were liberalised last week  by the government, prices of oil derivatives in the domestic market will be defined every month based on oil prices on international markets, he said.
“If oil prices on the global market go up, oil derivative prices in the Kingdom will be up, while if prices go down, fuel prices will automatically see a decrease,” noted Hiyari, who also heads the special pricing committee that includes representatives from the Ministry of Industry and Trade and the Jordan Petroleum Refinery Company.
Speaking to The Jordan Times in a telephone interview, he indicated that the government's decision to raise prices of fuel, which went into effect as of November 14, is valid until January 1 of next year.
The decision, which prompted protests and riots across the country, sent the price of 90-octane gasoline up by 15 per cent from JD0.70 a litre to JD0.80 a litre. 
Diesel and kerosene prices went up to JD0.685 per litre instead of JD0.515 a litre. The prices of the two products increased by 33 per cent.
Cooking gas saw the highest rise, with the price of a gas cylinder going up from JD6.5 to JD10.
Authorities say the decision to lift subsidies and sell fuel products at cost was taken to avoid further financial losses to the Treasury as the cost of subsidies on this year’s budget was estimated at JD800 million.
The new subsidy regime , under which direct cash payments will be delivered to low- and medium-income Jordanians, is expected to bring the cost on the budget to JD300 million a year.
Under the new system, each individual of a household that consists of six members or less and whose income is less than JD800 a month or JD10,000 a year will receive JD70 annually in compensation of the hike in prices
