What economic changes followed the Iranian Revolution and the Iran-Iraq War?

Following the 1979 Iranian Revolution and the subsequent Iran-Iraq War (1980–88), Iran’s economy underwent significant structural changes characterized by increased state intervention and the implementation of Islamic principles.

Key economic shifts included:

• State Control: The government nationalized private banks and insurance companies, gaining a virtual monopoly over major income-producing activities and increasing its control over foreign trade.1
• Constitutional Framework: The national constitution divided the economy into public, cooperative, and private sectors. Laws violating Islamic principles were declared void, leading to a prohibition on charging interest on loans and restrictions on financial speculation.1
• Ideological Debate: Two factions emerged: Islamic leftists, who advocated for extensive nationalization and a welfare state, and conservatives, who supported property rights and privatization. Both groups generally agreed on restricting Western banking practices.1
• Post-War Challenges: Despite efforts to move away from public control after 1990, the economy continued to struggle. Reformist attempts to encourage privatization and reduce state influence were often blocked, and economic policy increasingly favored the Islamic Revolutionary Guard Corps and other entities within the supreme leader’s circle.2
