Founded in 1874 and under the management of the Petersen Group since 2003, the Bank is an essential tool for the foreign trade operations of companies in the region.

Each of these banks are financial agents of their respective provinces of origin, where they lead in deposits and loans from the private sector, and maintain their rating for short-term debt at A1 (arg) and for long-term at AA− (arg) for its favorable performance, reflected in its capacity to generate profits, high liquidity and the quality of its portfolio.

The policies established by the Board of Directors to accompany, promote and sustain the growth of the provincial economy are reflected in the evolution of the market share, mainly in assistance to the non-financial private sector.

The bank's first Provisional Direction was composed of Carlos Casado del Alisal (presiding), Benjamín Ledesma, Manuel Carlés and Evaristo Machain, elected by vote, and Melitón Ibarlucea and Mariano Alvarado as representatives of the provincial government.

Its capital was divided in 20,000 stocks: 10,000 for the government, 4,000 for the founders, and 6,000 to be freely acquired by the private business of Rosario, a major port city on the Paraná River.
