The Singapore dollar is the official currency of the Republic of Singapore. It is divided into 100 cents. It is normally abbreviated with the dollar sign $, or S$ to distinguish it from other dollar-denominated currencies. The Monetary Authority of Singapore (MAS) issues the banknotes and coins of the Singapore dollar.

A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.
