In July 1940, facing challenging prospects at home following the German invasion of France, the Paris-based BNCI acquired the Banque de l'Union Nord-Africaine in Algiers to develop its activity outside Europe.
The BNCI renamed that bank as Banque Nationale pour le Commerce et l'Industrie en Afrique (BNCI-Afrique or BNCI-A), and opened a branch in Saint-Louis, Senegal simultaneously as another in Casablanca.
Following the loi-cadre Defferre of 1956, most sub-Saharan African French colonies became independent countries by 1960, and developed their own national banking policy frameworks.
Thus in 1962, four stand-alone banks were created in Cameroon, the Republic of the Congo, Côte d'Ivoire, and Senegal: respectively, the Banque internationale pour le Commerce et l'Industrie du Cameroun (BICI Cameroun) in Douala, the Banque internationale pour le Commerce et l'Industrie du Congo (BICI Congo) in Brazzaville, the Banque Internationale pour le Commerce et l'Industrie de la Côte d'Ivoire [fr] (BICICI) in Abidjan,[2] and the Banque Internationale pour le Commerce et l'Industrie du Sénégal [fr] (BICIS) in Dakar.
