That situation consolidated the strong social sensitiveness which is still an ideal and operating asset of Banca Intesa. In the post World War II period, the Saving Bank is among the protagonists in the reconstruction of Milan.

In the Fifties, during the Italian economic boom, it increased its activities in medium-term loans, especially in favour of lower-sized enterprises, through the foundation of Mediocredito Lombardo.

Starting from the Sixties, Cassa di Risparmio delle Provincie Lombarde was a commercial bank and in the following two decades it achieved a considerable territorial presence in Italy and abroad. In 1991, an important restructuring led to the merger of the subsidiary IBI and to the contribution by Ente Cassa di Risparmio delle Provincie Lombarde of its banking activities to a new company named Cariplo SpA.

Ente Cassa di Risparmio delle Provincie Lombarde, after that contribution, took the name of Fondazione Cariplo and pursues objectives of public interest and social benefit and solidarity. In 1997 the Chairman of Fondazione Cariplo, Giuseppe Guzzetti, and the Chairman of Banco Ambrosiano Veneto (BAV), Giovanni Bazoli signed an agreement for the integration between Cariplo and BAV which gave birth to Banca Intesa.
