Banque Indosuez is created by the merger of Banque de l’Indochine and Banque de Suez et de l’Union des Mines, both owned by Compagnie Financière de Suez. Between its establishment in 1975 and its acquisition by Crédit Agricole in 1996, Banque Indosuez undergoes a profound transformation to become the other major French merchant bank to compete with Paribas which is also active in private wealth management.
Its international network increases exponentially to include 60 countries, establishing a presence in the United States and returning to Banque de l'Indochine's historic territories. At the start of the 1980s, Banque Indosuez is one of the most established foreign banks in China, with offices in Beijing (1982), Shenzhen (1983) and Shanghai (1960 reopened in 1984). Having considerably developed its capital market activities, it innovates once more by opening the first trading floor in France in 1984.
The bank is nationalised (Act of 11 February 1982) then privatised in 1986, at the same time as its parent company Compagnie de Suez.
It joins Crédit Agricole group in 1996.
