The National Bank of Guinea-Bissau ( or BNG) was the central bank of Guinea-Bissau from February 1975 until May 1997, when Guinea-Bissau joined the Central Bank of West African States.
History
At independence in February 1975, Guinea-Bissau nationalized the Banco Nacional Ultramarino, Portuguese bank's branch, and transformed it into the country's central bank. The currency, Portuguese escudo, was replaced with Guinea-Bissau peso. In 1990, the bank was renamed as the Central Bank of Guinea Bissau (Banco Central da Guiné-Bissau).
In May 1997 Guinea-Bissau joined the francophone West African Monetary Union Union Économique et Monétaire Ouest-Africaine (UEMOA). Consequently, National Bank of Guinea-Bissau was converted as a national branch of Central Bank of West African States (BCEAO), and national currency Guinea Bissau peso was replaced by West African CFA franc.
