[1] Its first chief executive (French: directeur) was Jean-Baptiste Bellamy, who in 1857 moved on to head the Banque de la Martinique.
[2] The bank lost its issuance privilege in the turmoil of World War II, when the Caisse Centrale de la France d'Outre-Mer (CCFOM) was designated as monetary authority for the island and other French Caribbean territories on 1 July 1944.

It remained in activity as a commercial bank, the only one in French Guiana until the Banque Française Commerciale opened there in the late 1970s.
