Under the new pricing scheme, state television yesterday said each car on the road would see its monthly, 60-liter reduced-cost allowance jump to 7,000 rials (22 cents) per liter from 4,000 rials (12 cents). That works out to about 83 cents a gallon under the new pricing structure, compared to 45 cents under the former.
It said every liter after that will cost 10,000 rials (31 cents), up from 7,000 rials. That's a rise of USD 1.17 a gallon from 83 cents a gallon.
Iran began cutting energy and food subsidies in 2010 under then-President Mahmoud Ahmadinejad, part of what he described as a radical "surgery" to help the Islamic Republic's ailing economy as it faced increased international sanction for its contested nuclear program.
The second phase, which targeted further gasoline subsidy cuts, was to take effect in March 2012, but was pushed back over fears of stoking inflation.
But previous attempts to change the price at the pump have seen dissent. In 2007, protesters rioted and damaged gas stations over prices increasing, with authorities arresting dozens of people.
Iran consumes some 70 million liters of gasoline per day. Iran's refineries are unable to produce enough gasoline for its domestic production, so it must import supply from refineries abroad.
