The ouguiya is the official currency of Mauritania since 1973 when it replaced the CFA franc. The name is the Hassaniya Arabic pronunciation of “uqiyyah”, which means “ounce”. In 1973, The Central Bank of Mauritania (Banque Centrale de Mauritanie) issued notes in denominations of 100, 200 and 1000 ouguiya, followed by the 500 in 1974, 2000 in 2004 and 5000 ouguiya in 2010. In 2017, The Central Bank of Mauritania (Banque Centrale de Mauritanie) announced a redenomination of the ouguiya and second series of notes were issued in denomination of 50, 100, 200, 500 and 1000 ouguiya.
