MRUMauritanian OuguiyaMauritanian Ouguiya (MRU)
The Mauritanian ouguiya is Mauritania's official currency and the unit used for domestic prices, payments and government records. The Central Bank of Mauritania is the monetary authority responsible for issue and circulation. MRU is the ISO code for the current ouguiya, replacing the former MRO code after the 2018 redenomination. One ouguiya is divided into five khoums, an uncommon structure that matters when small values are displayed. CurrencyHub keeps MRU distinct from the historical code so current pages never mix two monetary scales.

Context
Why this currency matters
Mauritania introduced the new ouguiya in 2018 at a conversion of 10 old ouguiya for one new ouguiya. The central bank's currency information and current note series provide the basis for the modern unit. MRU is used in a market-based reference framework rather than being presented as a fixed dollar or euro currency. For travel and commercial records, the ISO code, the 2018 scale change and the provider date should be kept together. A retail exchange quote may use different rounding or customer charges. The ouguiya's five-khoums subdivision is a distinctive denomination feature, so reference material should distinguish the currency's formal unit from the way modern cash prices are displayed.
