How did nationalization of industries affect Peru’s economy in the late 20th century?

In the late 1960s and early 1970s, a military government in Peru implemented a program of economic nationalism, nationalizing industries such as petroleum, mining, and fish meal, and enacting extensive agrarian reform to address economic deficiencies.312

While intended to modernize the economy and reduce dependence on foreign interests, these policies ultimately created significant economic challenges. The consequences of this nationalization included:

• Financial Instability: The state faced massive government debt and high rates of inflation.3
• Trade Issues: The country experienced a large trade deficit and strained diplomatic and economic relations with key trading partners.3
• Economic Contraction: The combination of state-led management and external factors—such as the disappearance of anchovies due to El Niño and the devastating 1970 earthquake—severely hampered economic performance.312

These negative outcomes eventually compelled successive governments to reassess the state's role in the economy, leading to the reopening of certain sectors to private entrepreneurs and the implementation of structural reforms in the 1990s to foster economic growth.3
