Historical Context
Understanding STN/MRU historical data
STN/MRU records how many mauritanian ouguiya units one são tomé and príncipe dobra represented at each provider publication. Both currencies are associated with Africa, but they remain separate monetary units with their own issuing and policy arrangements. The series can support dated price comparisons, cross-currency records and research into how the relationship changed over the selected period.
Observed movement can reflect relative inflation, economic activity, monetary-policy conditions, trade and demand for the two currencies. The documented exchange-rate arrangements also provide context: Fixed relationship with the euro; Market-based exchange-rate framework. These are historical reference observations, not intraday transaction prices, forecasts or evidence that a single factor caused a particular change.
Exchange-rate information is provided for reference only and is not financial, trading or investment advice.
Source and calculation method
CurrencyHub preserves the requested date separately from the actual provider publication date. Monthly and annual averages are arithmetic means of available daily observations, and the month-end value is the final published observation in that calendar month. No missing weekend or holiday rate is invented or interpolated. Review the policy that applies to any accounting, tax or legal use.
Data interpretation note
These observations are reference rates for comparison and research, not bank execution prices. A requested weekend or holiday may have no publication because the provider follows its own release calendar; CurrencyHub identifies the actual published date instead of inventing or interpolating a value. Banks and payment services can use different processing dates, spreads and fees.
