The São Tomé doblea is the official currency of the Democratic Republic of São Tomé and Príncipe, with the ISO currency code STN, issued and managed by the country's Central Bank, and is used primarily for day-to-day domestic transactions and financial activities.
The São Tomé doblea circulates only in São Tomé and Príncipe, an island nation located in the Gulf of Guinea on the west coast of Africa, consisting of the islands of São Tomé and Príncipe, where the use of the currency is strictly regulated by local laws.
The São Tomé doblea is denominated in cents, with 1 doblea equaling 100 cents. Banknotes are available in denominations of 5, 10, 20, 50, 100 and 200 dobras, while coins are available in denominations of 10, 20 and 50 cents, as well as 1 and 2 dobras, making it easy to pay in different scenarios.
São Tomé dobras replaced the Portuguese escudo as the country's first currency after independence in 1977, initially coded STD, and changed to STN in 2018 to improve currency stability and implement an exchange rate mechanism pegged to the euro, reflecting its economic transition.
