The story

In 1924, João Moreira Salles established the Casa Bancária Moreira Salles (Moreira Salles Banking House) in the city of Poços de Caldas, state of Minas Gerais. His son Walter Moreira Salles was named an acting partner in 1933 at the young age of twenty-one.

Acquisitions

Regional mergers

In 1940, Banco Moreira Salles catalyzed its growth by merging with three regional banks, eventually changing its name to União de Bancos Brasileiros (Unibanco).

Acquisition of Banco Nacional

Over time, Unibanco relocated its headquarters to São Paulo, in the state of São Paulo, the principal financial center of Brazil. The institution expanded steadily and became the country's third-largest privately owned bank, a position strengthened by its acquisition of Banco Nacional in 1995. Banco Nacional had entered into financial difficulties and ultimately failed during the banking crisis that accompanied the initial years of the Real Plan, a period in which several major Brazilian financial institutions were restructured or liquidated.

Merger with Banco Itaú

On November 2, 2008, Unibanco and the second largest Brazilian private banking group, Banco Itaú, announced plans for a merger. The merger was approved by the Central Bank of Brazil in late February 2009. As a result of the merger process, Unibanco agencies became new Itaú agencies by the end of 2010, and the Itaú name became the strongest brand in the Brazilian private sector banking market. The defunct bank's name survives in the new merged bank's holding company, which became Itaú Unibanco Holding S.A. However, only the Itaú brand is now used in the bank's corporate image.
