About the US Dollar to São Tomé and Príncipe Dobra rate
This page converts the US Dollar (USD) into the São Tomé and Príncipe Dobra (STN) at the mid-market rate. Both currencies trade continuously on the foreign exchange market, and the ratio between them moves with interest rates, inflation and the trade flows between their economies. The rate shown here is the neutral reference each bank, card network and bureau de change then builds its own price on top of.
Every figure on this page is a mid-market reading of USD/STN, dated above. It says where the pair stood at that time, not where it is heading: no rate here is a forecast, a quote, or an offer to exchange.
