After a period of turbulence in the 1980s and 90s, Latin American banks are coming into their own. Buoyed by a number of growing economies throughout the region and the adoption of international regulatory standards, the region’s financial sector is going through a period of enormous transition.

Today, the largest banks in Latin America are largely concentrated in two countries. Brazil claims the five biggest institutions by asset size and six of the top ten spots. Meanwhile, Mexico is host to the four other banks on the list.

Santander Mexico provides a wide range of consumer products, including mortgages, credit cards and personal loans. The bank, a division of Spanish-headquartered Santander (SAN ). also caters to business clients. Services include pension fund services, financing solutions and foreign trade services.

9) Banorte. Mexico ($74 billion in assets)

Banorte was opportunistic in the wake of the Mexican financial crisis in the 1990s, acquiring multiple banks and building its presence throughout the country. Officially known as Grupo Financiero Banorte, the bank offers retail banking products as well as investment services, annuity and insurance products, retirement funds and warehousing capabilities.

8) BTG Pactual. Brazil ($81 billion in assets)

Founded in 1983, BTG Pactual Group is a highly diversified financial services company.

Like some several other Latin American banks, Santander Brasil is actually part of a larger European bank – in this case, Spanish-based Santander. In addition to retail banking, credit cards and home loans, the organization offers asset management and commercial banking services.

Established in 1969, Caixa is a “private government entity” with a close relationship to the Brazilian Ministry of Finance. The bank plays a key role in executing income transfer programs and putting national housing policies into effect. It also manages the country’s lottery program. (L28)
