US Dollar to Mauritanian Ouguiya exchange rate history
What moves the Mauritanian Ouguiya rate
The Mauritanian ouguiya is driven by iron ore, its leading export, alongside a major fishing sector and contributions from gold and copper. These natural resources set most of the supply of foreign currency, so the exchange rate responds to extracted volumes and world commodity prices. When iron prices or fish catches slip, foreign-currency earnings contract. To anticipate the ouguiya, follow iron-ore output and prices, fishing activity and the flows of gold and copper, because it is this resource bounty that governs the foreign-currency liquidity of a largely extractive economy. Resource revenue, more than any domestic policy lever, sets how much hard currency reaches the market.
Converting and sending the Mauritanian Ouguiya: what to know
The ouguiya was redenominated in 2018, with ten old units exchanged for one new one, so current notes reflect that change. It is unusual in being subdivided into five khoums rather than into hundredths, a quirk worth noting on local pricing. As a managed currency in a resource-dependent economy, its conditions are tied to how resource revenue is running. For senders and receivers, the main practical points are to use the post-2018 denominations, be aware of the five-khoum subdivision, and recognise that the currency is steered rather than freely floating in a market shaped by commodities.
About the US Dollar
The US Dollar (USD, $) is the world's primary reserve currency and the de facto reference rate for most African remittance pricing. It is issued by the Federal Reserve System and subdivided into 100 cents. For African routes, the USD plays two distinct roles: as the on-the-wire settlement currency that originating remittance providers use to hedge between markets, and as the unit of account that diaspora senders most often think in. When operators quote a USD-to-local-currency rate, the difference between that rate and the interbank mid-market — the spread — is where most of the route's cost is hidden, often dwarfing the visible send fee. For receivers in countries with thin USD interbank markets such as Sierra Leone or Mozambique, the published rate can lag the interbank reference by several percentage points.
About the Mauritanian Ouguiya
The Mauritanian ouguiya, issued by the Banque Centrale de Mauritanie, is one of the world's few currencies not built on a power of ten: it is subdivided into five khoums rather than into hundredths. In 2018 the unit was redenominated, with ten old ouguiya exchanged for one new one, streamlining prices after years of erosion. Mauritania, straddling the Sahara and the Atlantic, draws its export earnings chiefly from iron ore and from a rich fishing sector off its coast. Those two resource streams supply much of the foreign currency that backs the ouguiya and shape its everyday strength.
