Dariush Baqer-Javan added that this is mostly because of the rise in gasoline price since mid-November.
On Nov. 15, the National Iranian Oil Products Distribution Company announced that gasoline has been rationed and prices raised by at least 50-200%.
Since then, private car owners can buy 60 liters of subsidized gasoline every month with a fuel card at 15,000 rials (10 cents) per liter, up 50%. Additional purchases (maximum 250 liters a month) will cost 30,000 rials (21 cents) per liter, up 200%.
