This paper examines why financial reforms in several Latin American countries during the 1970s, aimed at ending "financial repression," led to widespread bankruptcies, government interventions, and low domestic savings by 1983. It highlights the paradox of Chile, Argentina, and Uruguay, where financial liberalization resulted in a de facto socialized banking system. The paper discusses the inherent imperfections of financial markets, the legal prerequisites for efficient operation, and the stylized facts of financial liberalization in Latin America, particularly in the Southern Cone. It also explores alternative ways to organize domestic capital markets under Latin American conditions and considers policies regarding the links between domestic and international financial markets. The paper notes that financial markets are not perfect, and that banks differ from other firms in that they deal with future obligations and require creditworthiness assessments. Financial intermediaries rely on borrowed funds, and depositors are concerned about the safety of their money. A purely laissez-faire financial system would require an efficient judiciary and police system to enforce contracts and handle disputes. However, in practice, most countries have maintained government control over the money supply and banking systems, with deposit insurance and regulations to prevent bank runs. The paper also discusses the financial history of Latin America, noting that by the 1920s, most countries had established commercial banks. The 1930s saw the expansion of government financial institutions, which helped prevent bank panics. However, by the 1950s, financial repression had led to a segmented domestic financial market. In the 1960s, financial reforms were introduced, including indexing of loans and deposits. Post-1964 Brazil attempted to revive the domestic financial system with indexing devices and government supervision. The Southern Cone countries, particularly Chile, undertook financial reforms in the 1970s, leading to a fully nationalized banking sector and the eventual liberalization of financial markets. However, this led to a financial crisis, with bank failures and government interventions. The paper argues that the lack of effective supervision and the reliance on private financial agents contributed to the crisis. The experience of Chile highlights the challenges of financial liberalization, including the need for effective regulation and the risks of moral hazard. The paper concludes that a balanced approach to financial regulation is necessary, combining public and private financial agents to ensure stability and efficiency. It suggests that public development banks can play a crucial role in supporting long-term capital formation and addressing the uncertainties in Latin American societies. The paper also emphasizes the importance of a stable real exchange rate and the need for careful management of capital flows to avoid financial instability.This paper examines why financial reforms in several Latin American countries during the 1970s, aimed at ending "financial repression," led to widespread bankruptcies, government interventions, and low domestic savings by 1983.
