Singapore pegged its dollar to British Pound Sterling until the early 1970s, then to the US Dollar for a short period of time. From 1973 to 1985, Singapore pegged its currency against a fixed and undisclosed trade-weighted basket of currencies, reflecting its diversified trade links.
From 1985 onwards, the Singapore Dollar has floated within an undisclosed bandwidth, closely monitored by the Monetary Authority of Singapore (MAS) to guard against imported inflation and ensure that Singapore's exports remain competitive.
