Banque Internationale d’Investissement (BII) is a universal bank serving individuals, businesses, professionals, and institutions in Mauritania. Established in 2006, it has built two decades of local experience and a banking culture shaped by its history with ING and Société Générale. After operating as Société Générale Mauritanie, the institution returned to its original BII name following a change in ownership involving the Ballouhey Group and Enko Capital consortium. The bank presents itself as a long-term financial partner, emphasizing proximity, soundness, and rigorous standards, including transaction security, risk control, and banking confidentiality.

BII offers banking solutions for individuals’ everyday needs and personal projects, as well as services for organizations, including cash-flow management and project financing. Its stated areas of support include savings, loans, and investments. Customers can access their accounts through the myBII digital service and use existing accounts, cards, and checkbooks. The bank also provides branch and customer-service support, handles complaints, and shares career opportunities.
