Reserve currency in the context of "Australian dollar"

The United States dollar (symbol: $; currency code: USD) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.

The U.S. dollar was originally defined under a bimetallic standard of 371.25 grains (24.057 g) (0.7734375 troy ounces) fine silver or, from 1834, 23.22 grains (1.505 g) fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important international reserve currency after the First World War, and displaced the pound sterling as the world's primary reserve currency by the Bretton Woods Agreement towards the end of the Second World War. The dollar is the most widely used currency in international transactions, and a free-floating currency. It is also the official currency in several countries and the de facto currency in many others, with Federal Reserve Notes (and, in a few cases, U.S. coins) used in circulation.

A currency symbol or currency sign is a graphic symbol used to denote a currency unit. Usually it is defined by a monetary authority, such as the national central bank for the currency concerned.

A symbol may be positioned in various ways, according to national convention: before, after or between the numeric amounts: $2.50, 2,50€ and 250.

The Bretton Woods system of monetary management established the rules for commercial relations among 44 countries, including the United States, Canada, Western European countries, and Australia, after the 1944 Bretton Woods Agreement until the Jamaica Accords in 1976. The Bretton Woods system was the first example of a fully negotiated monetary order intended to govern monetary relations among independent states. The Bretton Woods system required countries to guarantee convertibility of their currencies into U.S. dollars to within 1% of fixed parity rates, with the dollar convertible to gold bullion for foreign governments and central banks at US$35 per troy ounce of fine gold (or 0.88867 gram fine gold per dollar). It also envisioned greater cooperation among countries in order to prevent future competitive devaluations, and thus established the International Monetary Fund (IMF) to monitor exchange rates and lend reserve currencies to countries with balance of payments deficits.

Preparing to rebuild the international economic system while World War II was still being fought, 730 delegates from all 44 Allied countries gathered at the Mount Washington Hotel in Bretton Woods, New Hampshire, United States, for the United Nations Monetary and Financial Conference, also known as the Bretton Woods Conference. The delegates deliberated from 1 to 22 July 1944, and signed the Bretton Woods agreement on its final day. Setting up a system of rules, institutions, and procedures to regulate the international monetary system, these accords established the IMF and the International Bank for Reconstruction and Development (IBRD), which today is part of the World Bank Group. The United States, which controlled two-thirds of the world's gold, insisted that the Bretton Woods system rest on both gold and the US dollar. Soviet representatives attended the conference but later declined to ratify the final agreements, charging that the institutions they had created were "branches of Wall Street". These organizations became operational in 1945 after a sufficient number of countries had ratified the agreement. According to Barry Eichengreen, the Bretton Woods system operated successfully due to three factors: "low international capital mobility, tight financial regulation, and the dominant economic and financial position of the United States and the dollar."

The yen (Japanese: 円; symbol: ¥; code: JPY) is the official currency of Japan. It is the third-most traded currency in the foreign exchange market, after the United States dollar and the euro. It is also widely used as a third reserve currency after the US dollar and the euro.

The New Currency Act of 1871 introduced Japan's modern currency system, with the yen defined as 1.5 g (0.048 troy ounces) of gold, or 24.26 g (0.780 troy ounces) of silver, and divided decimally into 100 sen or 1,000 rin. The yen replaced the previous Tokugawa coinage as well as the various hansatsu paper currencies issued by feudal han (fiefs). The Bank of Japan was founded in 1882 and given a monopoly on controlling the money supply.

The United States dollar was established as the world's foremost reserve currency by the Bretton Woods Agreement of 1944. It claimed this status from sterling after the devastation of two world wars and the massive spending of the United Kingdom's gold reserves. Despite all links to gold being severed in 1971, the dollar continues to be the world's foremost reserve currency. Furthermore, the Bretton Woods Agreement also set up the global post-war monetary system by setting up rules, institutions and procedures for conducting international trade and accessing the global capital markets using the U.S. dollar.

The U.S. dollar is widely held by central banks, foreign companies and private individuals worldwide, in the form of eurodollar foreign deposit accounts (not to be confused with the euro), as well as in the form of US$100 notes, an estimated 75% of which are held overseas. The U.S. dollar is predominantly the standard currency unit in which goods are quoted and traded, and with which payments are settled in, in the global commodity markets.

Sterling (symbol: £; currency code: GBP) is the currency of the United Kingdom and nine of its associated territories. The pound is the main unit of sterling, and the word pound is also used to refer to the British currency generally, often qualified in international contexts as the British pound or the pound sterling.

Sterling is the world's oldest currency in continuous use since its inception. In 2022, it was the fourth-most-traded currency in the foreign exchange market, after the United States dollar, the euro, and the Japanese yen. Together with those three currencies and the renminbi, it forms the basket of currencies that calculate the value of IMF special drawing rights. As of late 2022, sterling is also the fourth most-held reserve currency in global reserves.
