Portugal was the first independent nation to follow Britain in joining the gold standard. Although beset by persistent current account deficits and heavily dependent on foreign capital inflows, it enjoyed a relatively stable tenure of 37 years on gold. This paper shows how it was possible to secure currency stability, despite a lower credibility for the peg and a higher incidence of gold point violations than in core countries. The explanation lies in the central role played by institutional actors, such as the Bank of Portugal and/or the government, whose interventions in the exchange market kept the parity within the band.
