Since the liberalization of its trade in the mid-1980s, Mexico has pursued an aggressive globalization strategy, which today makes it the country with the most free trade agreements in the world. This liberalization strategy has also included the banking sector, particularly since 1997, when all restrictions to the entry of foreign banks were removed. The history of the banking sector in Mexico includes episodes of nationalization in 1982, privatization in 1992, and near-complete failure in 1995. Since then, however, the Mexican government has undertaken a series of bold reforms that have contributed to the modernization of its financial system. This paper documents the evolution of Mexico’s banking sector starting from its nationalization in 1982 and culminating with the increased entry of foreign banks in recent years that has driven the recovery of bank credit to the private sector.
