Indicative rates, not an offer. Averaged from real buy and sell prices.
Portugal uses the euro (EUR); US dollars, British pounds, Swiss francs and Brazilian reais are the most exchanged, the latter thanks to strong ties with Brazil. Lisbon and Porto have the most offers, followed by Faro, Braga, Coimbra and Funchal on Madeira.
Exchange offices operate at airports and in tourist centres such as Baixa in Lisbon and Ribeira in Porto. In Portugal, P2P offers let you swap USDT or USDC for euros or exchange US dollars directly with another person.
