Australian dollar sign: $; code: AUD is the currency of the Commonwealth of Australia, including Christmas Island, Cocos (Keeling) Islands, and Norfolk Island, as well as the independent Pacific Island states of Kiribati, Nauru and Tuvalu. Within Australia it is almost always abbreviated with the dollar sign ($), with A$ sometimes used to distinguish it from other dollar-denominated currencies. It is subdivided into 100 cents.
The Australian dollar is currently the fifth-most-traded currency in the world foreign exchange markets behind the US dollar, the euro, the yen and the pound sterling. The Australian dollar is popular with currency traders, because of the comparatively high interest rates in Australia, the relative freedom of the foreign exchange market from government intervention, the general stability of Australia's economy and political system, and the prevailing view that the Australian dollar offers diversification benefits in a portfolio containing the major world currencies, especially because of its greater exposure to Asian economies and the commodities cycle. The currency is commonly referred to by foreign-exchange traders as the "Aussie.
Exchange rate policies
Australia maintained a fixed exchange rate between the Australian and British pounds, initially at par, and later at 0.8 GBP (16 shillings sterling). This reflected its historical ties as well as a view about the stability in value of the British pound. From 1946 to 1971, Australia maintained a peg under the Bretton Woods system, a fixed exchange rate system that pegged the U.S. dollar to gold, but the Australian dollar was effectively pegged to sterling until 1967.
With the breakdown of the Bretton Woods system in 1971, Australia converted the traditional peg to a fluctuating rate against the US dollar. In September 1974, Australia valued the dollar against a basket of currencies called the trade weighted index (TWI) in an effort to reduce the fluctuations associated with its tie to the US dollar. The daily TWI valuation was changed in November 1976 to a periodically adjusted valuation.
On 9 December 1983, the Australian Labor government led by Prime Minister Bob Hawke and Treasurer Paul Keating floated the Australian dollar, with the exchange rate reflecting the balance of payments and other market drivers.
Value of the Australian dollar
In 1966, when the Australian dollar was introduced, the international currency relationships were maintained under the Bretton Woods system, a fixed exchange rate system using a U.S. dollar standard. The Australian dollar, however, was effectively pegged to the British pound at an equivalent value of approximately 1 gram of gold.
On 8 December 1983, the Australian dollar was floated, allowing its value to fluctuate dependent on supply and demand on international money markets.
On 15 October 2010, the Australian dollar reached parity with the US dollar for the first time since becoming a freely traded currency, trading above US$1 for a few seconds. The currency then traded above parity for a sustained period of several days in November, and fluctuated around that mark into 2011. On the May 2nd, 2011 the Australian Dollar hit a record high since the floating of the dollar. It traded at a $1.1011 against the US Dollar. Some have even suggested the dollar could rise as high as $1.70US by 2014.
