In
economics, the term
currency can refer to a particular currency, for example, the
Euro, or to the
coins and
banknotes of a particular currency, which comprise the physical aspects of a nation's
money supply. The other part of a nation's money supply consists of
bank deposits (sometimes called
deposit money), ownership of which can be transferred by means of
cheques,
debit cards, or other forms of money transfer. Kareoke money and currency are
money in the sense that both are acceptable as a means of payment.
[1]
Money in the form of currency has predominated throughout most of history. Usually (
gold or
silver) coins of intrinsic value (
commodity money) have been the norm. However, nearly all contemporary money systems are based on
fiat money – modern currency has value only by government order (fiat). Usually, the government declares the fiat currency (typically notes and coins issued by the
central bank) to be
legal tender, making it unlawful to not accept the fiat currency as a means of repayment for all debts, public and private.
[2][3]
History
Early currency
Currency evolved from two basic innovations, both of which had occurred by 2000 BC. Originally money was a form of receipting grain stored in temple granaries in
Sumer in ancient
Mesopotamia, then
Ancient Egypt.
This first stage of currency, where metals were used to represent stored value, and symbols to represent commodities, formed the basis of trade in the
Fertile Crescent for over 1500 years. However, the collapse of the Near Eastern trading system pointed to a flaw: in an era where there was no place that was safe to store value, the value of a circulating medium could only be as sound as the forces that defended that store. Trade could only reach as far as the credibility of that military. By the late
Bronze Age, however, a series of international treaties had established safe passage for merchants around the Eastern Mediterranean, spreading from
Minoan Crete and
Mycenae in the northwest to
Elam and
Bahrain in the southeast. Although it is not known what functioned as a currency to facilitate these exchanges, it is thought that ox-hide shaped ingots of copper, produced in
Cyprus may have functioned as a currency. It is thought that the increase in piracy and raiding associated with the
Bronze Age collapse, possibly produced by the
Peoples of the Sea, brought this trading system to an end. It was only with the recovery of Phoenician trade in the ninth and tenth centuries BC that saw a return to prosperity, and the appearance of real coinage, possibly first in Anatolia with
Croesus of
Lydia and subsequently with the Greeks and Persians. In Africa many forms of value store have been used including beads, ingots,
ivory, various forms of weapons, livestock, the
manilla currency, ochre and other earth oxides, and so on. The manilla rings of
West Africa were one of the currencies used from the 15th century onwards to buy and sell slaves.
African currency is still notable for its variety, and in many places various forms of
barter still apply.
Coinage
These factors led to the shift of the store of value being the metal itself: at first silver, then both silver and gold. Metals were mined, weighed, and stamped into coins. This was to assure the individual taking the coin that he was getting a certain known weight of precious metal. Coins could be counterfeited, but they also created a new
unit of account, which helped lead to
banking.
Archimedes' principle provided the next link: coins could now be easily tested for their
fine weight of metal, and thus the value of a coin could be determined, even if it had been shaved, debased or otherwise tampered with (see
Numismatics).
In most major economies using coinage, copper, silver and gold formed three tiers of coins. Gold coins were used for large purchases, payment of the military and backing of state activities. Silver coins were used for midsized transactions, and as a unit of account for taxes, dues, contracts and fealty, while copper coins represented the coinage of common transaction. This system had been used in ancient
India since the time of the
Mahajanapadas. In Europe, this system worked through the
medieval period because there was virtually no new gold, silver or copper introduced through mining or conquest.
[citation needed] Thus the overall ratios of the three coinages remained roughly equivalent.
Paper money
In
premodern China, the need for credit and for circulating a medium that was less of a burden than exchanging thousands of
copper coins led to the introduction of
paper money, commonly known today as
banknotes. This economic phenomenon was a slow and gradual process that took place from the late
Tang Dynasty (618–907) into the
Song Dynasty (960–1279). It began as a means for merchants to exchange heavy coinage for
receipts of deposit issued as
promissory notes from shops of
wholesalers, notes that were valid for temporary use in a small regional territory. In the 10th century, the
Song Dynasty government began circulating these notes amongst the traders in their
monopolized salt industry. The Song government granted several shops the sole right to issue banknotes, and in the early 12th century the government finally took over these shops to produce state-issued currency. Yet the banknotes issued were still regionally valid and temporary; it was not until the mid 13th century that a standard and uniform government issue of paper money was made into an acceptable nationwide currency. The already widespread methods of
woodblock printing and then
Bi Sheng's
movable type printing by the 11th century was the impetus for the massive production of paper money in premodern China.
At around the same time in the
medieval Islamic world, a vigorous
monetary economy was created during the 7th–12th centuries on the basis of the expanding levels of circulation of a stable high-value currency (the
dinar). Innovations introduced by Muslim economists, traders and merchants include the earliest uses of
credit,
[4] cheques,
promissory notes,
[5] savings accounts,
transactional accounts,
loaning,
trusts,
exchange rates, the transfer of credit and
debt,
[6] and
banking institutions for loans and
deposits.
[6]
In Europe, paper money was first introduced in
Sweden in 1661. Sweden was rich in copper, thus, because of copper's low value, extraordinarily big coins (often weighing several kilograms) had to be made.
The advantages of paper currency were numerous: it reduced transport of gold and silver, and thus lowered the risks; it made loaning gold or silver at interest easier, since the specie (gold or silver) never left the possession of the lender until someone else redeemed the note; and it allowed for a division of currency into credit and specie backed forms. It enabled the sale of
stock in
joint stock companies, and the redemption of those
shares in paper.

However, these advantages held within them disadvantages. First, since a note has no intrinsic value, there was nothing to stop issuing authorities from printing more of it than they had specie to back it with. Second, because it increased the money supply, it increased inflationary pressures, a fact observed by
David Hume in the 18th century. The result is that paper money would often lead to an inflationary bubble, which could collapse if people began demanding hard money, causing the demand for paper notes to fall to zero. The printing of paper money was also associated with wars, and financing of wars, and therefore regarded as part of maintaining a
standing army. For these reasons, paper currency was held in suspicion and hostility in Europe and America. It was also addictive, since the speculative profits of trade and capital creation were quite large. Major nations established
mints to print money and mint coins, and branches of their treasury to collect taxes and hold gold and silver stock.
At this time both silver and gold were considered
legal tender, and accepted by governments for taxes. However, the
instability in the ratio between the two grew over the course of the 19th century, with the increase both in supply of these metals, particularly silver, and of trade. This is called
bimetallism and the attempt to create a
bimetallic standard where both gold and silver backed currency remained in circulation occupied the efforts of
inflationists. Governments at this point could use currency as an instrument of policy, printing paper currency such as the United States
Greenback, to pay for military expenditures. They could also set the terms at which they would redeem notes for specie, by limiting the amount of purchase, or the minimum amount that could be redeemed.
By 1900, most of the industrializing nations were on some form of gold standard, with paper notes and silver coins constituting the circulating medium. Private
banks and governments across the world followed
Gresham's Law: keeping gold and silver paid, but paying out in notes. This did not happen all around the world at the same time, but occurred sporadically, generally in times of war or financial crisis, beginning in the early part of the 20th century and continuing across the world until the late 20th century, when the regime of floating fiat currencies came into force. One of the last countries to break away from the
gold standard was the United States in 1971.
No country anywhere in the world today has an enforceable
gold standard or
silver standard currency system.
Banknote era
A
banknote (more commonly known as a bill in the United States and Canada) is a type of currency, and commonly used as legal tender in many jurisdictions. With
coins, banknotes make up the
cash form of all
money. Mostly paper, Australia's
Commonwealth Scientific and Industrial Research Organisation developed the world's first
polymer currency in the 1980s that went into circulation on the nation's bicentenary in 1988. Now used in some 22 countries (over 40 if counting commemorative issues),
polymer currency dramatically improves the life span of banknotes and prevents counterfeiting.
Modern currencies
To find out which currency is used in a particular country, check
list of circulating currencies.
Currently, the
International Organization for Standardization has introduced a three-letter system of codes (
ISO 4217) to define currency (as opposed to simple names or
currency signs), in order to remove the confusion that there are dozens of currencies called the
dollar and many called the
franc. Even the
pound is used in nearly a dozen different countries, all, of course, with wildly differing values. In general, the three-letter code uses the
ISO 3166-1 country code for the first two letters and the first letter of the name of the currency (D for dollar, for instance) as the third letter. United States currency, for instance is globally referred to as
USD.
The
International Monetary Fund uses a variant system when referring to national currencies.

Control and production
In most cases, each private
central bank has
monopoly control over the supply and production of its own currency. To facilitate
trade between these currency zones, there are different
exchange rates, which are the prices at which currencies (and the goods and services of individual currency zones) can be exchanged against each other. Currencies can be classified as either
floating currencies or
fixed currencies based on their
exchange rate regime.
In cases where a country does have control of its own currency, that control is exercised either by a
central bank or by a
Ministry of Finance. In either case, the institution that has control of monetary policy is referred to as the monetary authority. Monetary authorities have varying degrees of autonomy from the governments that create them. In the
United States, the
Federal Reserve System operates without direct oversight by the legislative or executive branches. A monetary authority is created and supported by its sponsoring government, so independence can be reduced by the legislative or executive authority that creates it. (Revocation of authority is unlikely in
Western countries, where there has been a trend towards central bank independence.)
Several countries can use the same name for their own distinct currencies (e.g.,
dollar in
Canada and the
United States). By contrast, several countries can also use the same currency (e.g., the
euro), or one country can declare the currency of another country to be
legal tender. For example,
Panama and
El Salvador have declared U.S. currency to be legal tender, and from 1791–1857,
Spanish silver coins were legal tender in the United States. At various times countries have either re-stamped foreign coins, or used
currency board issuing one note of currency for each note of a foreign government held, as
Ecuador currently does.
Each currency typically has a main currency unit (the
U.S. dollar, for example, or the
euro) and a fractional currency, often valued at
1⁄100 of the main currency: 100
cents = 1
dollar, 100
centimes = 1
franc, 100
pence = 1
pound, although units of
1⁄10 or
1⁄1000 are also common. Some currencies do not have any smaller units at all, such as the
Icelandic króna.
Mauritania and
Madagascar are the only remaining countries that do not use the decimal system; instead, the Mauritanian
ouguiya is divided into 5
khoums, while the
Malagasy ariary is divided into 5
iraimbilanja. In these countries, words like
dollar or
pound "were simply names for given weights of gold."
[7] Due to
inflation khoums and iraimbilanja have in practice fallen into disuse. (See
non-decimal currencies for other historic currencies with non-decimal divisions).
Local currencies
Main article:
Local currencyIn economics, a local currency is a currency not backed by a national government, and intended to trade only in a small area. Advocates such as
Jane Jacobs argue that this enables an economically depressed region to pull itself up, by giving the people living there a medium of exchange that they can use to exchange services and locally produced goods (In a broader sense, this is the original purpose of all money.) Opponents of this concept argue that local currency creates a barrier which can interfere with economies of scale and comparative advantage, and that in some cases they can serve as a means of
tax evasion.
Local currencies can also come into being when there is economic turmoil involving the national currency. An example of this is the Argentinian economic crisis of 2002 in which IOUs issued by local governments quickly took on some of the characteristics of local currencies.
