In November 2019, Iran raised the gasoline prices by 50% and imposed a strict rationing system again (as in 2007). The prices per liter gasoline rose to 15,000 rials, where only 60 liters were permitted to private cars for a month. Besides, oil purchase beyond the limit would cost 30,000 rials per liter. Those prices are still well below target prices set in the subsidy reform plan, however. The policy changes came in effect to the US sanctions, and caused protests across the country. The result of the rationing, a year later, was reduced pollution and wasteful domestic consumption and increase in exports.
