The Iranian targeted subsidy plan (Persian: طرح هدفمندسازی یارانهها) also known as the subsidy reform plan was passed by the Iranian Parliament on January 5, 2010. The government has described the subsidy plan as the "biggest surgery" to the nation's economy in half a century and "one of the most important undertakings in Iran's recent economic history". The goal of the subsidy reform plan is to replace subsidies on food and energy (80% of total) with targeted social assistance, in accordance with Five Year Economic Development Plan and move towards free market prices in a 5-year period. The subsidy reform plan is the most important part of a broader Iranian economic reform plan. According to the government, approximately $100 billion per year is spent on subsidizing energy prices ($45 billion for the prices of fuel alone) and many consumable goods including bread, sugar, rice, cooking oil and medicine. However, some experts believe direct subsidies are about $30 billion, depending on oil prices. The subsidy system has been inherited from the Iran-Iraq war era but was never abolished. Iran is one of the largest gasoline consumers in the world, ranking second behind the United States in consumption per car. The government subsidy reform has been years in the making for various reasons. Iran's Supreme Leader has backed the government's latest subsidy reform plan.
