What is Currency?
Currency is a universal medium of exchange for goods and services in an economy, and it is believed to have been used as such dating back at least 3,000 years. Before this, it is assumed that bartering, which is the exchange of goods and services without the use of money, was likely used. Throughout history, the currency has taken many different forms. Some examples include coins, barley, gold, silver, squirrel pelts, 8-ton carved limestone rocks, salt, knives, cowrie shells, stamps, potato mashers, peppercorn, tea bricks, and cheese.
History of Currency
As history has shown, anything that a group of people in an economy attaches value to can be used as currency. The first "official" currency was minted in the seventh century BC by King Alyattes of Lydia in modern-day Turkey. For practical reasons, Lydian currency took on the form of a round coin, which became the first ever standardized unit of currency. Paper currency, on the other hand, was invented in Asia and was brought back to Europe by Marco Polo after his travels to Asia.
Modern Currency
Modern currency is much more uniform and regulated. Major currencies in the world today take on the physical form of paper bills or coins which are easily carried on a person, but most of a person's currency is typically stored in digital accounts. The value of these currencies is backed by the promise of their issuing governments, which makes them fiat money (currency declared by the government to be an official medium of payment but is not backed by a physical commodity). Before fiat money existed, currencies were usually backed by a commodity such as gold or silver.
While modern currency is physically represented by coins and paper bills, most large-scale currency transactions are done electronically. Modern technology utilizes sophisticated currency exchange mechanisms and systems to exchange currencies between digital accounts rather than physically. Even the exchange of currency for everyday goods and services such as groceries or haircuts involves physical currencies less and less due to the growing popularity of debit cards, credit cards, and mobile payments.
Forex and Exchange Rates
Currencies used in different countries are rarely, if ever, exactly equal in value. As a result, exchange rates (the rate at which a currency is exchanged for another) exist to enable the equal exchange of currencies. Real-time exchange rates are supplied by the foreign exchange market (forex), the same place where most currency transactions take place. The forex is a global, decentralized, over-the-counter market for the trading of currencies. Each day, trillions of dollars (US) worth of currency are traded. The market functions at high speeds, with exchange rates changing every second. The most common forex transactions are exchanges between the U.S. dollar and European euro, the U.S. dollar and the Japanese yen, and the U.S. dollar to the British pound Sterling.
