Understanding STN/SOS historical data
STN/SOS records how many somali shilling units one são tomé and príncipe dobra represented at each provider publication.

The documented exchange-rate arrangements also provide context: Fixed relationship with the euro; SOS operates within Somalia's rebuilding national monetary framework, with extensive practical use of foreign currency and mobile payments..

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.
