Egypt slashed fuel subsidies on Saturday giving only a couple of hours warning of the impending price hikes.
The move prompted protests on the streets that were dispersed by police using teargas.
Natural gas and fuels for cars all saw dramatic increases with some fuels rising in price by as much as 80 per cent.
Speaking at a press conference on Saturday Prime Minister Ibrahim Mehleb said that the decision to raise prices was taken after detailed studies.
How can I achieve social justice while I am subsidising for the rich [at] the expense of the poor? he said.
Analysts remain concerned that the poor will still lose out prompting further civil unrest.
Theyre going to have to put some kind of safety net in and there has been talk of direct cash transfers to help the poor, but none of these systems are in place yet, said Oliver Coleman, an analyst at UK risk consultancy Maplecroft.
There is a risk that Egypt will end up with a plan that is half implemented: subsidies will be cut and the poor wont be supported. Much has been made about [President Abdel Fattah] Al-Sisis position and how strong he is, but this is an area where he is vulnerable. There could be severe consequences if the cost of living rises and Al-Sisi knows this.
The price hikes come days after Al-Sisi signed off a budget that outlined a cut in fuel subsidies by almost a third.
On 30 June, Finance Minister Hany Kadry Dimian said the countrys fuel bill would be cut from £E144bn ($20bn) last year to £E100bn.
The austerity drive is part of an attempt to reduce Egypts budget deficit to 10 per cent of GDP.
The shortfall reached an estimated 12 per cent of GDP last year as the countrys subsidy bills continued to balloon and instability meant many holidaymakers stayed away, denying the country revenue from tourism.
Although the price hikes have been met with resistance by Egyptians struggling to make ends meet amid increasing unemployment, the countrys Gulf donors and foreign oil companies are likely to be pleased by the move, which shows Al-Sisi is serious about resolving the countrys economic problems.
Last year, cuts were outlined in the budget but were not enforced due to fear of unrest.
Over the past 12 months, Egypt has received more than $20bn from Gulf states eager to see Al-Sisi remain in power.
At the heart of Egypts fiscal problems is an energy crisis. A rapid expansion in Egypts population has seen natural gas consumption rocket forcing the former natural gas exporter to seek imports.
