A currency[a] is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins.[1][2] A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state.[3] Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies.[4] Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.
Other definitions of the term currency appear in the respective synonymous articles: banknote, coin, and money. This article uses the definition which focuses on the currency systems of countries.
One can classify currencies into three monetary systems: fiat money, commodity money, and representative money, depending on what guarantees a currency's value (the economy at large vs. the government's precious metal reserves). Some currencies function as legal tender in certain jurisdictions, or for specific purposes, such as payment to a government (taxes), or government agencies (fees, fines). Others simply get traded for their economic value.
The concept of a digital currency has arisen in recent years. Whether government-backed digital notes and coins (such as the digital renminbi in China, for example) will be successfully developed and implemented remains unknown.[5] Digital currencies that are not issued by a government monetary authority, such as cryptocurrencies like Bitcoin, are different because their value is market-dependent and has no safety net. Various countries have expressed concern about the opportunities that cryptocurrencies create for illegal activities such as scams, ransomware (extortion), money laundering and terrorism.[6] In 2014, the United States IRS advised that virtual currency is treated as property for federal income-tax purposes, and it provides examples of how long-standing tax principles applicable to transactions involving property apply to virtual currency.[7]
