Mauritanian Ouguiya (MRO): Overview and History
The Mauritanian ouguiya (MRO) is the official currency of the Islamic Republic of Mauritania, a country in Northwest Africa. It is issued and regulated by the Central Bank of Mauritania (Banque Centrale de Mauritanie). The currency code MRO is used in international transactions, and its symbol is UM. The ouguiya was introduced in 1973, replacing the CFA franc at a rate of 1 ouguiya = 5 CFA francs. Notably, the ouguiya is one of the few currencies in the world that is not subdivided into 100 units; instead, one ouguiya is divided into 5 khoums, although khoums are rarely used in practice due to their low value.
The economy of Mauritania is largely based on agriculture, livestock, fishing, and mining, particularly iron ore and gold. The value of the ouguiya is influenced by these commodity exports, as well as by the country's trade balance and foreign exchange reserves. The Central Bank of Mauritania manages the currency's exchange rate through a managed float system, intervening in the foreign exchange market to maintain stability. However, like many emerging market currencies, the ouguiya can be subject to fluctuations due to economic and political factors.
For those interested in currency exchange, it is important to note that the MRO is not widely traded outside of Mauritania, and exchange rates may vary significantly between different providers. Travelers to Mauritania are advised to carry cash in major currencies such as the euro or US dollar, which can be exchanged at local banks or exchange offices. As with any currency, it is advisable to check current exchange rates before making transactions, as rates can change frequently.
