The CPA inherited the activities previously managed by popular banks (Banque Populaire Commerciale et Industrielle in Algiers, Oran, Annaba, Constantine) as well as other foreign banks, Banque Alger Misr, Société Marseillaise du Crédit and Compagnie Française de Crédit et de Bank (CFCB). In 1985, the CPA gave birth to the Local Development Bank (BDL), after the sale of 40 branches, the transfer of 550 employees and executives and 89,000 customer accounts. In 1989, it was established as a Public Economic Company (EPE), legally structured as a joint-stock company.
