In trade, barter is a system of exchange in which participants in a transaction directly exchange goods or services for other goods or services without using a medium of exchange, such as money. Economists distinguish barter from gift economies in many ways; barter, for example, features immediate reciprocal exchange, not one delayed in time. Barter usually takes place on a bilateral basis, but may be multilateral. In most developed countries, barter usually exists parallel to monetary systems only to a very limited extent. Market actors use barter as a replacement for money as the method of exchange in times of monetary crisis, such as when currency becomes unstable or simply unavailable for conducting commerce.
A currency in the most specific sense is money in any form when in use or circulation as a medium of exchange, especially circulating banknotes and coins. A more general definition is that a currency is a system of money in common use, especially for people in a nation. Under this definition, U.S. dollars (US$), euros (€), Japanese yen (¥), and pounds sterling (£) are examples of currencies. These various currencies are recognized as stores of value and are traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are defined by governments, and each type has limited boundaries of acceptance.
The euro is the official currency of 19 of the 27 member states of the European Union. This group of states is known as the eurozone or euro area and includes about 343 million citizens as of 2019. The euro, which is divided into 100 cents, is the second-largest and second-most traded currency in the foreign exchange market after the United States dollar.
The European Currency Unit was a unit of account used by European Economic Community composed of a basket of member country currencies. The ECU came in to operation on 13 March 1979, and was assigned the ISO 4217 code. The ECU replaced the European Unit of Account (EUA) at parity in 1979, and it was later replaced by the euro (EUR) at parity on 1 January 1999.
The Maastricht Treaty, concluded in 1992 between the 12 member states of the European Communities, is the foundation treaty of the European Union (EU). Formally the Treaty on European Union, it announced "a new stage in the process of European integration" chiefly in provisions for a shared European citizenship, for the eventual introduction of a single currency, and for common foreign and security policies. Although these were widely seen to presage a "federal Europe", the focus of constitutional debate shifted to the later 2007 Treaty of Lisbon. In the wake of the Eurozone debt crisis unfolding from 2009, the most enduring reference to the Maastricht Treaty has been to the rules of compliance – the "Maastricht criteria" – for the currency union.
In finance, an exchange rate is the rate at which one national currency will be exchanged for another. It is also regarded as the value of one country's currency in relation to another currency. For example, an interbank exchange rate of 114 Japanese yen to the United States dollar means that ¥114 will be exchanged for US$1 or that US$1 will be exchanged for ¥114. In this case it is said that the price of a dollar in relation to yen is ¥114, or equivalently that the price of a yen in relation to dollars is $1/114.
The eurozone, officially called the euro area, is a monetary union of 19 member states of the European Union (EU) that have adopted the euro (€) as their primary currency and sole legal tender. The monetary authority of the eurozone is the Eurosystem. Eight members of the European Union continue to use their own national currencies, although most of them will be obliged to adopt the euro in the future.
In macroeconomics, hard currency, safe-haven currency or strong currency is any globally traded currency that serves as a reliable and stable store of value. Factors contributing to a currency's hard status might include the stability and reliability of the respective state's legal and bureaucratic institutions, level of corruption, long-term stability of its purchasing power, the associated country's political and fiscal condition and outlook, and the policy posture of the issuing central bank.
Government debt, also known as public interest, public debt, national debt and sovereign debt, contrasts to the annual government budget deficit, which is a flow variable that equals the difference between government receipts and spending in a single year. The debt is a stock variable, measured at a specific point in time, and it is the accumulation of all prior deficits.
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.
Chiemgauer is a regional local currency started in 2003 in Prien am Chiemsee, Bavaria, Germany. Named after the Chiemgau, a region around the Chiemsee lake, it is intended to increase local employment, supporting local culture, and make the local food supply more resilient. The Chiemgauer operates with a fixed exchange rate, tied to the value of the euro: 1 Chiemgauer = €1.
In economics, an optimum currency area (OCA) or optimal currency region (OCR) is a geographical region in which it would maximize economic efficiency to have the entire region share a single currency.
In the foreign exchange market and international finance, a world currency, supranational currency, or global currency is a currency that is transacted internationally, with no set borders.
The United Kingdom did not seek to adopt the euro as its official currency for the duration of its membership of the European Union (EU), and secured an opt-out at the euro's creation via the Maastricht Treaty in 1992: Bank of England was only a member of the European System of Central Banks.
The Totnes pound (t£) was a complementary local currency, intended to support the local economy of Totnes, a town in Devon, England. It was in circulation from March 2007 to June 2019, when it was discontinued due partly to an increasingly cashless economy.
The international status and usage of the euro has grown since its launch in 1999. When the euro formally replaced 12 currencies on 1 January 2002, it inherited their use in territories such as Montenegro and replaced minor currencies tied to the pre-euro currencies, such as in Monaco. Four small states have been given a formal right to use the euro, and to mint their own coins, but all other usage outside the eurozone has been unofficial. With or without an agreement, these countries, unlike those in the eurozone, do not participate in the European Central Bank or the Eurogroup.
Hans-Peter Friedrich is a German politician of the Christian Social Union (CSU) who has been serving as a member of the German Bundestag since 1998. Under the leadership of Chancellor Angela Merkel, he served as Federal Minister of the Interior (2011-2013) and as Minister for Food and Agriculture (2013). Friedrich resigned from that position in February 2014. Friedrich has a controversial history with minorities in Germany, causing outrage in 2013 after telling journalists that Islam in Germany is not something supported by history at any point.
Fiscal localism comprises institutions of localized monetary exchange. Sometimes considered a backlash against global capitalism or economic globalization, fiscal localism affords voluntary, market structures that help communities trade more efficiently within their communities and regions.
A Greek withdrawal from the eurozone was a hypothetical scenario under which Greece would withdraw from the Eurozone to deal with the now expired Greek government-debt crisis. This conjecture has been referred to as "Grexit", a portmanteau combining the English words "Greek" and "exit", and which has been expressed in Greek as ελλέξοδος,. The term "Graccident" was coined for the case that Greece exited the EU and the euro unintentionally. These terms first came into use in 2012 and have been revitalised at each of the bailouts made available to Greece since then.
Withdrawal from the Eurozone denotes the process whereby a Eurozone member-state, whether voluntarily or forcibly, stops using the euro as its national currency and leaves the Eurozone. As of January 2021, no country has withdrawn from the Eurozone.
