A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. 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. 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. 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.
A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves.
In economics, inflation is a general increase in the prices of goods and services in an economy. This is usually measured using a consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices faced by households do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose.
A commodity market is a market that trades in the primary economic sector rather than manufactured products, such as cocoa, fruit and sugar. Hard commodities are mined, such as gold and oil. Futures contracts are the oldest way of investing in commodities. Commodity markets can include physical trading and derivatives trading using spot prices, forwards, futures, and options on futures. Farmers have used a simple form of derivative trading in the commodities market for centuries for price risk management.
Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies. PPP is effectively the ratio of the price of a market basket at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of tariffs, and other transaction costs.
As part of the theory of Freiwirtschaft, Freigeld is a monetary unit proposed by Silvio Gesell.
A reserve currency is a foreign currency that is held in significant quantities by central banks or other monetary authorities as part of their foreign exchange reserves. The reserve currency can be used in international transactions, international investments and all aspects of the global economy. It is often considered a hard currency or safe-haven currency.
A store of value is any commodity or asset that would normally retain purchasing power into the future and is the function of the asset that can be saved, retrieved and exchanged at a later time, and be predictably useful when retrieved.
In economics, unit of account is one of the functions of money. A unit of account is a standard numerical monetary unit of measurement of the market value of goods, services, and other transactions. Also known as a "measure" or "standard" of relative worth and deferred payment, a unit of account is a necessary prerequisite for the formulation of commercial agreements that involve debt.
Bernard Lietaer was a Belgian civil engineer, economist, author, and educator. He studied monetary systems and promoted the idea that communities can benefit from creating their own local or complementary currency, which circulate parallel with national currencies.
A complementary currency is a currency or medium of exchange that is not necessarily a national currency, but that is thought of as supplementing or complementing national currencies. Complementary currencies are usually not legal tender and their use is based on agreement between the parties exchanging the currency. According to Jérôme Blanc of Laboratoire d'Économie de la Firme et des Institutions, complementary currencies aim to protect, stimulate or orientate the economy. They may also be used to advance particular social, environmental, or political goals.
ANCAP is an alternative currency system that uses ammonium nitrate, copper, aluminium and plywood as the units of exchange. The system was first proposed in 1982 by the economist Robert Hall. ANCAP is an example of a commodity standard.
Demurrage is the cost associated with owning or holding currency over a given period. It is sometimes referred to as a carrying cost of money. For commodity money such as gold, demurrage is the cost of storing and securing the gold. For paper currency, it can take the form of a periodic tax, such as a stamp tax, on currency holdings. Demurrage is sometimes cited as economically advantageous, usually in the context of complementary currency systems.
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.
There are two different types of world currency unit in use today that have different origins and usages.
The Future of Money: Beyond Greed and Scarcity is a book written by Bernard Lietaer, published by Random House in 2001, and currently out of print. It was written as an overview of how money and the financial system works, the effects of modern money paradigms, especially relating to debt and interest, and how it can work to everyone's benefit to solve a wide range of problems, especially with the use of complementary currencies. The book is meant to be written for the layperson, while bringing light to subjects that only relatively few are aware of at all levels of society.
A fixed exchange rate, often called a pegged exchange rate, is a type of exchange rate regime in which a currency's value is fixed or pegged by a monetary authority against the value of another currency, a basket of other currencies, or another measure of value, such as gold.
Fiat money is a type of government issued currency that is not backed by a precious metal, such as gold or silver, or backed by any other tangible asset or commodity. Fiat currency is typically designated by the issuing government to be legal tender, and is authorized by government regulation. Since the end of the Bretton Woods system in 1971, the major currencies in the world are fiat money.
Margrit Kennedy was a German architect, professor, environmentalist, author and advocate of complementary currencies and an interest- and inflation-free economy. In 2011, she initiated the movement Occupy Money.
