are us dollars the same as australian dollars
Australian dollar In 2016, the Australian dollar was the fifth most traded currency in the world, accounting for 6.9% of the world's daily share (down from 8.6% in 2013).[4] It trades in the world foreign exchange markets behind the US dollar, the euro, the yen and the pound sterling.[5] 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.[6] The currency is commonly referred to by foreign-exchange traders as the "Aussie dollar".
Currency A currency (from Middle English: curraunt, "in circulation", from Latin: currens, -entis), in the most specific use of the word, refers to money in any form when in actual use or circulation as a medium of exchange, especially circulating banknotes and coins.[1][2] A more general definition is that a currency is a system of money (monetary units) in common use, especially in a nation.[3] Under this definition, US dollars, British pounds, Australian dollars, European euros and Russian ruble are examples of currency. These various currencies are recognized stores of value and are traded between nations in foreign exchange markets, which determine the relative values of the different currencies.[4] Currencies in this sense are defined by governments, and each type has limited boundaries of acceptance.
