The Singapore dollar or dollar (sign: $; code: SGD) is the official currency of Singapore. It is normally abbreviated with the dollar sign $, or alternatively S$ to distinguish it from other dollar-denominated currencies. It is divided into 100 cents. The Monetary Authority of Singapore and the Brunei Currency and Monetary Board still maintain the historic exchangeability of their two currencies, the Singaporean dollar and the Brunei dollar, respectively. The Singapore dollar is accepted as “customary tender” in Brunei according to the Currency Interchangeability Agreement. Likewise, the Brunei dollar is customarily accepted in Singapore.
