The Singapore dollar is the official currency of Singapore. The Singapore dollar is fixed with the currency of neighboring country, Brunei. One Singapore dollar is always equal to one Brunei dollar, and is also accepted as a legal trading currency in Brunei under these two countries' Interchangeability Agreement of 1967. As with all other dollar currencies, the Singapore dollar is decimalized and can be broken down into 100 cents. Singapore dollar notes are issued in $2, $5, $10, $50, $100, $10,000 and $10,000 bills. Coinage is minted as 1, 5, 10, 20 and 50 cents and $1 coins.
The Brunei Dollar is accepted as a legal currency in Singapore, and can be used for trade all across Singapore. As the two currencies are pegged together, the Brunei dollar is valued equally to the Singapore dollar. Brunei dollar notes are issued in $1, $5, $10, $25, $50, $100, $500, $1,000 and $10,000 bills. The Brunei dollar is divided into 100 sen. Banknotes consist of both paper notes and polymer notes. Polymer notes are used for the lower values such as the $1, $5 and $10. Banknote sizes vary from bigger sizes for the higher values to smaller sizes for the lower values. Coins are minted as 1, 5, 10, 20 and 50 sen. The old $1 coin is still accepted as a legal tender, although it is no longer minted in Brunei, and will soon be out of circulation.
The U.S. dollar, Australian dollar, yen and pounds sterling are not officially recognized trade tenders across Singapore, but will be accepted in many of the large shopping centers. Singapore economy does not restrict import or export of local and foreign currencies. In case of emergency you might be able to use your dollars or pounds, but don't count on it. Rather, have some Singapore dollars on you. Take note that many banks in Singapore don't do foreign exchange dealings on Saturdays.
