Patagonia Bank
Argentine commercial bank serving individual customers, small and medium-sized businesses, and corporate clients.
Last updated August 26, 2026
Overview
Banco Patagonia is an Argentine commercial bank headquartered in Buenos Aires. Its business serves individual customers, small and medium-sized enterprises, and larger corporate clients through a network of service points in Argentina and a broader regional presence. The bank offers personal and corporate banking, investment services, insurance, and international banking products. The institution traces its origins to 1976, when it was established as a brokerage house. Its initial shareholder group included Jorge and Ricardo Stuart Milne and Emilio González Moreno. The business expanded beyond securities and brokerage activities during the 1980s. After entering the automobile-loan market in 1987, it became a commercial bank in 1988 under the name Banco Mildesa. A major change in scale came in 1996, when Banco Mildesa acquired the newly privatized Banco de Río Negro. The transaction broadened the bank's geographic and commercial base. In 2000, the institution adopted the Banco Patagonia name, drawing on the regional identity associated with Río Negro and Patagonia. The rebranding marked the bank's development from a smaller financial institution into a more broadly positioned Argentine banking franchise. Banco Patagonia expanded again in the early 2000s. In 2003 it acquired the assets and business of insolvent Banco Sudameris, including the portfolio associated with Caja de Ahorro, described in reference material as Argentina's largest savings and loan institution. In 2004, the bank absorbed Lloyds TSB's Argentine operations. These transactions increased its customer base, branch and service-point coverage, and competitive position. The bank subsequently became one of Argentina's larger banking institutions and developed operations or branches connected with Brazil and Uruguay. The bank's distribution model combines physical service points in Argentina with digital and conventional banking channels. Reference material describes approximately 200 service points in the country's principal cities and provincial capitals and more than 775,000 customers, although those figures are time-sensitive and are not treated here as current operating data. Its customer proposition spans everyday banking, lending, deposits, investments, insurance, and cross-border services rather than a single specialist financial niche. Banco Patagonia is part of Banco do Brasil's corporate group. Banco do Brasil is identified in the reference material as holding 58.96 percent of Banco Patagonia's shares. The bank has also been publicly traded in Argentina and had previously been listed in Brazil. Its ownership and listing structure distinguish it from a privately held regional bank while leaving its principal commercial identity rooted in the Argentine financial market.
History
Banco Patagonia began in 1976 as a brokerage house. Its founding shareholder group included Jorge and Ricardo Stuart Milne and Emilio González Moreno. The original business was centered on financial intermediation rather than full commercial banking, but it later broadened its activities as Argentina's financial-services market developed. The first major strategic expansion described in the available reference material occurred in 1987, when the institution entered automobile lending. That move extended the business into a consumer-credit segment and was followed in 1988 by its transformation into a commercial bank under the name Banco Mildesa. The new banking structure allowed it to offer a wider range of deposit, lending, and other financial products. In 1996, Banco Mildesa acquired the newly privatized Banco de Río Negro. The acquisition was an important turning point because it added a regional banking platform and strengthened the institution's reach beyond its earlier brokerage and lending activities. Four years later, in 2000, the bank changed its name to Banco Patagonia. The name connected the institution with the Patagonia region and reflected the importance of its Río Negro-related banking heritage. The next period of expansion was driven by acquisitions. In 2003, Banco Patagonia acquired insolvent Banco Sudameris. The transaction included a portfolio associated with Caja de Ahorro, identified in the reference material as Argentina's largest savings and loan institution. In 2004, Banco Patagonia absorbed Lloyds TSB's Argentine operations. Together, these deals expanded the bank's assets, customer relationships, and market presence and helped position it among Argentina's larger banks. The bank's activities developed across several customer groups. It serves individuals through personal banking, savings, lending, and related services; small and medium-sized businesses through commercial banking; and corporate customers through financing, treasury, investment, and international services. It also provides insurance and investment products. Its physical network has been described as comprising about 200 service points in the main cities and provincial capitals of Argentina, while its customer base has been reported at more than 775,000. Because the reference does not provide a date for the current status of those figures, they should be understood as historical or reported indicators rather than verified present-day totals. Banco Patagonia also developed a regional dimension, with branches or operations in Brazil and Uruguay mentioned in the reference material. It became publicly traded on the Buenos Aires Stock Exchange and had previously been listed on the BM&F Bovespa in São Paulo. The institution is controlled by Banco do Brasil, which is reported to own 58.96 percent of Banco Patagonia's shares. This ownership relationship places the Argentine bank within a major Brazilian banking group while its principal operating identity remains that of an Argentine commercial bank. By the late 2010s, Banco Patagonia was presented as a diversified financial institution rather than a narrowly specialized lender. Its service mix covered retail and business banking, investments, insurance, and international banking. A 2019 reference reports that it received a Best Bank award at the Fortuna Awards. No reliable source material supplied for this entry establishes a subsequent change in ownership, operating status, executive leadership, or principal business model.
