About the AUD/MRU rate
The AUD/MRU rate is how many MRU one Australian dollar buys. It moves constantly with interest-rate expectations, commodity prices and global risk sentiment - see what moves the rate. Tradergy shows the mid-market reference rate and does not forecast where it’s heading. For the 52-week highs and lows and a daily table, see the AUD/MRU rate history.

Every AUD pair sits on the convert hub, and to work in more than one currency at once there is the currency converter.
Who is allowed to quote the ouguiya
Four banks are permitted to make prices in the Mauritanian ouguiya, and the list is reviewed twice a year. The International Monetary Fund records the number of market makers reduced from eleven to four in October 2024, with the Banque Centrale de Mauritanie monitoring their quotes, their traded volume and their prudential compliance, and reassessing the number and quality of market makers every six months. Pending a new system it monitors whether firm quotes are honoured and issues fines where they are not.
That short list exists because there was barely a market to make prices in. The Fund records a foreign exchange trading platform established in December 2023, and puts the position before it starkly: the central bank had been supplying ninety-nine per cent of the foreign exchange reaching the market. By the end of April 2025 eighty per cent of volume was trading bank to bank on the platform, with the Bank providing the remainder through auctions.
The Bank publishes the results of those auctions rather than only their outcome. Its adjudications page carries, for each session, a band minimum, a band maximum and a reference rate, downloadable as a data file and charted as a series running back to 2008.
One change removed an ambiguity that had run through every government transaction. The Fund records a rule change under which government dealings in dollars and euros are conducted in the afternoon at the Bank's reference rate fixed at 12:30 that same day, expressly so that two different rates would not apply on one day.
Two formal irregularities were cleared in the same period. The Fund records that Mauritania eliminated two multiple currency practices in February 2025, one arising from the weighted average rate of the Bank's auctions and one from the reference rates used in its transactions with the government and other public entities.
