The Nuovo Banco Ambrosiano was the bank replacing the Banco Ambrosiano after its collapse. In 1989 the bank merged with the Banca Cattolica del Veneto to form the Banco Ambrosiano Veneto. In 1998 the latter bank formed the Banca Intesa together with the Cassa di Risparmio delle Provincie Lombarde (Cariplo).
