The dobra is the official currency of the São Tomé and Príncipe since 1977, when it replaced the escudo. The name derived from Portuguese “dobra” which means doubloon (double). In 1977, the Banco Nacional de São Tomé e Príncipe introduced notes in denominations of 50, 100, 500 and 1000 dobras, followed by 5000, 10,000, 20,000 and 50,000 dobras note in 1996. In 2018, the Central Bank of São Tomé and Príncipe (Banco Central de São Tomé e Príncipe) announced a redenomination of the dobra and second series of notes were issued in denomination of 5, 20, 50, 100 and 200 dobras.
In 2009, the government of São Tomé and Príncipe signed a loan contract with Portugal, which aimed to link the dobra to the euro. This measure would guarantee economic stability in the country and make the country attractive for foreign financial investment.
