[4] The bank was founded in 1905 as the Banco de Galicia y Buenos Aires by a consortium led by Manuel Escasany, a jeweler and clockmaker of Galician origin.

The Buenos Aires branches were followed by one in neighboring Montevideo, Uruguay, in 1910, and in 1921, it began offering time deposits (which remain the most common form of savings among the Argentine public).

[5] Following the founder's death in 1948, his son, Eduardo Escasany, became its president and by 1960, he had secured a partnership with the Ayerzas and the Brauns, two influential local families prominent in the Argentine ranching and retail sectors, respectively.

As of April 2009, the group maintained 236 branches and total deposits in Argentina amounted to nearly US$4.5 billion, a 6% market share, and 7.6% among private sector depositors.

Grupo Galicia comprises the Buenos Aires Stock Exchange's blue-chip MERVAL Index and are included in the Morgan Stanley Capital International and Standard & Poor's indices, as well.

Additionally, a portion of shares is held by Julián Aristiqui, a discreet figure in Argentina’s financial sector known for his investments in banking, media, and fintechs, including early-stage ventures.
