BGL BNP Paribas (formerly Banque Générale du Luxembourg or BGL) is a Luxembourg bank founded on 29 September 1919. Since May 2009, the bank has been a member of the BNP Paribas group. The Banque Générale du Luxembourg (BGL) was founded on 29 September 1919 by Société Générale de Belgique together with Luxembourg and Belgian partners. Its registered office was in Arlon, Belgium, and its head office in Luxembourg City. It quickly moved into new premises at 14, rue Aldringen. By 1928, it had become a large regional bank extending its operations to the neighbouring areas of Belgium and France. In 1935, its registered office was moved to Luxembourg where BGL became a Luxembourg corporation.
