What are the Major Currencies?

US Dollar - $US
Also referred to as the dollar, greenback and buck.

The US Dollar was adopted by the Congress of the Confederation of the United States on July 6, 1785 and is the most used in international transactions. Several countries use the U.S. dollar as their official currency, and many others allow it to be used in a de facto capacity.

In 1995, over US$380 billion were in circulation, of which two-thirds was outside the United States. By 2005, those figures had doubled to nearly $760 billion with an estimated half to two-thirds being held overseas, which is an annual growth of about 7.6%. However, as of December 2006, the dollar was surpassed by the euro in terms of combined value of cash in circulation.

The value of euro notes in circulation has risen to more than € 610 billion, equivalent to US$800 billion at the exchange rates at this time.

The U.S. dollar uses the decimal system, consisting of 100 (equal) cents (symbol ¢).

The Euro - €
The euro (currency sign: €; banking code: EUR) is the official currency of the European states of Austria, Belgium, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Slovenia and Spain - also known as the Eurozone - and is the single currency for more than 317 million people in Europe.

Including areas using currencies pegged to the euro, the euro affects more than 480 million people worldwide, with more than €610 billion in circulation as of December 2006. While all EU member states are eligible to join if they comply with certain monetary requirements, the euro is not used in all of the European Union as not all EU members have adopted the currency. All nations which have recently joined the EU are pledged to adopt the euro in due course, but the United Kingdom and Denmark are under no such obligation. Several small European states (The Vatican, Monaco and San Marino), although not EU members, have adopted the euro due to currency unions with member states. Andorra, Montenegro and Kosovo have adopted the euro unilaterally.

The Yen - ¥
The yen or (Japanese yen) is the currency of Japan. It is also widely used as a reserve currency after the United States dollar and euro.

The yen was introduced by the Meiji government in 1870 as a system resembling those in Europe. The yen replaced the complex monetary system of the Edo period, based on the mon.

The mon was a currency of Japan until 1870, as there were hundreds of different styles of currency throughout Japanese history, of many shapes, styles, designs, sizes, and materials, including gold, silver, bronze, etc. Even rice was once a currency, the koku.

The yen lost most of its value during and after World War II; after a period of instability, the yen was pegged at 1 US dollar = ¥360 from April 25, 1949, to until 1971 when the Bretton Woods system collapsed and the value of the yen began to float. After the Plaza Accord of 1985, the yen appreciated against the US dollar, until it reached a peak of about ¥85 per dollar in the mid 1990s. After that, the Bank of Japan adopted a weak yen policy which has held it in the range of ¥100-120 per dollar. In the last couple of years, the yen has grown weaker and weaker against not only the dollar but against nearly all other important world currencies due to a de facto zero interest rate policy which has encouraged massive yen carry trades, where speculators borrow in yen and buy bonds and other assets in currencies that charge significant interest. This can be very profitable, but is a short position on the yen, which in the absence of other factors drives the yen's value down.

The relative value of the yen is determined in foreign exchange markets by the economic forces of supply and demand. The supply of the yen in the market is governed by the desire of yen holders to exchange their yen for other currencies to purchase goods, services, or assets. The demand for the yen is governed by the desire of foreigners to buy goods and services in Japan and by their interest in investing in Japan (buying yen-denominated real and financial assets).

The Great British Pound - £
Other Names - Sterling, Cable and the Pound

The pound (symbol: £; ISO code: GBP), divided into 100 pence, is the official currency of the United Kingdom and the Crown Dependencies. The slang term "quid" is very common in the UK.

The official full name pound sterling (plural: pounds sterling) is used mainly in formal contexts and also when it is necessary to distinguish the currency used within the United Kingdom from others that have the same name. The Sterling is the third most traded currency in the world, after the US dollar and the euro.

The Swiss Franc - CHF
The franc (ISO 4217: CHF or 756) is the currency and legal tender of Switzerland and Liechtenstein. The Italian exclave Campione d'Italia and the German exclave Büsingen also use the Swiss franc. Franc banknotes are issued by the central bank of Switzerland, the Swiss National Bank, while coins are issued by the federal mint, Swissmint.

The Swiss franc is the only version of the franc still issued in Europe. Its name in the four official languages of Switzerland is Franken (German), franc (French and Rhaeto-Romanic), and franco (Italian). The smaller denomination, which is worth a hundredth of a franc, is called Rappen (Rp.) in German, centime (c.) in French, centesimo (ct.) in Italian and rap (rp.) in Rhaeto-Romanic. Users of the currency commonly write CHF (the ISO code), though SFr. is still common. SwF has been used in some publications but is not an official abbreviation.

The current franc was introduced in 1850 at par with the French franc. It replaced the different currencies of the Swiss cantons, some of which had been using a franc (divided into 10 batzen and 100 rappen) which was worth 1½ French francs.

In 1865, France, Belgium, Italy, and Switzerland formed the Latin Monetary Union where they agreed to change their national currencies to a standard of 4.5 grams of silver or 0.290322 grams of gold. Even after the monetary union faded away in the 1920s and officially ended in 1927, the Swiss franc remained on that standard until 1967.

As of November 30, 2006, the Swiss franc was worth US$ 0.826729 or € 0.628625. Since mid-2003, its exchange rate with the Euro has been stable at a value of about 1.55 CHF per Euro, so that the Swiss Franc has risen and fallen in tandem with the Euro against the U.S. dollar and other currencies.

The Swiss franc has historically been considered a safe haven currency with virtually zero inflation and a legal requirement that a minimum 40% is backed by gold reserves. However this link to gold, which dates from the 1920s, was terminated on 1 May 2000 following an amendment to the Swiss Constitution. The Swiss franc has suffered devaluation only once, on 27 September 1936 during the Great Depression, when the currency was devalued by 30% following the devaluations of the British pound, U.S. dollar and French franc.

The Australian Dollar
The Australian dollar (currency code AUD) has been, since 14 February 1966, 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. It is normally abbreviated with the dollar sign $. Alternatively A$ or $A, $AU or AU$ is used to distinguish it from other dollar-denominated currencies. It is sometimes affectionately called the "Aussie battler"; during a low period (relative to the U.S. dollar) around 2001 and 2002 the currency was sometimes locally called the "Pacific Peso". It is divided into 100 cents.

The Australian dollar is currently the sixth-most-traded currency in world foreign exchange markets (behind the U.S. dollar, the euro, the yen, the Pound sterling, and the Swiss franc), accounting for approximately 4-5% of worldwide foreign exchange transactions. The Australian dollar is popular with currency traders due to the relative lack of government intervention in the foreign exchange market, the general stability of the economy and government as well as the prevailing view that it offers diversification benefits in a portfolio containing the major world currencies (especially because of its greater exposure to Asian economies and the commodities cycle).
