Retail Banking was strengthened in 1997 through the acquisition of Crédit du Nord, highlighting the Group's determination to capitalise on the restructuring of the French banking system. At the same time, Société Générale looked to secure the long-term loyalty of its customers (launch of "one account number for life" and introduction of Jazz, a package of service offers). In 1999 it entered into a merger agreement with rival bank Paribas, but this was scuppered by a competitor, the Banque Nationale de Paris (BNP).
