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.
The euro is the official currency of 20 of the 27 member states of the European Union. This group of states is officially known as the euro area or, commonly, the eurozone, and includes about 344 million citizens as of 2023. The euro is divided into 100 euro cents.

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.
In finance, an exchange rate is the rate at which one currency will be exchanged for another currency. Currencies are most commonly national currencies, but may be sub-national as in the case of Hong Kong or supra-national as in the case of the euro.

The Lithuanian litas (ISO currency code LTL, symbolized as Lt; plural litai or litų was the currency of Lithuania, until 1 January 2015, when it was replaced by the euro. It was divided into 100 centų. The litas was first introduced on 2 October 1922 after World War I, when Lithuania declared independence, and was reintroduced on 25 June 1993 following a period of currency exchange from the Soviet ruble to the litas with the temporary talonas then in place. The name was modeled after the name of the country. From 1994 to 2002, the litas was pegged to the U.S. dollar at the rate of 4 to 1. The litas was pegged to the euro at the rate of 3.4528 to 1 since 2002. The euro was expected to replace the litas by 1 January 2007, but persistent high inflation and the economic crisis delayed the switch. On 1 January 2015 the litas was switched to the euro at the rate of 3.4528 to 1.
In macroeconomics and modern monetary policy, a devaluation is an official lowering of the value of a country's currency within a fixed exchange-rate system, in which a monetary authority formally sets a lower exchange rate of the national currency in relation to a foreign reference currency or currency basket. The opposite of devaluation, a change in the exchange rate making the domestic currency more expensive, is called a revaluation. A monetary authority maintains a fixed value of its currency by being ready to buy or sell foreign currency with the domestic currency at a stated rate; a devaluation is an indication that the monetary authority will buy and sell foreign currency at a lower rate.
Foreign exchange reserves are cash and other reserve assets such as gold held by a central bank or other monetary authority that are primarily available to balance payments of the country, influence the foreign exchange rate of its currency, and to maintain confidence in financial markets. Reserves are held in one or more reserve currencies, nowadays mostly the United States dollar and to a lesser extent the euro.
An exchange rate regime is a way a monetary authority of a country or currency union manages the currency about other currencies and the foreign exchange market. It is closely related to monetary policy and the two are generally dependent on many of the same factors, such as economic scale and openness, inflation rate, the elasticity of the labor market, financial market development, and capital mobility.
The Convertibility plan was a plan by the Argentine Currency Board that pegged the Argentine peso to the U.S. dollar between 1991 and 2002 in an attempt to eliminate hyperinflation and stimulate economic growth. While it initially met with considerable success, the board's actions ultimately failed. The peso was only pegged to the dollar until 2002.
In macroeconomics and economic policy, a floating exchange rate is a type of exchange rate regime in which a currency's value is allowed to fluctuate in response to foreign exchange market events. A currency that uses a floating exchange rate is known as a floating currency, in contrast to a fixed currency, the value of which is instead specified in terms of material goods, another currency, or a set of currencies.

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 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.
The United States dollar was established as the world's foremost reserve currency by the Bretton Woods Agreement of 1944. It claimed this status from sterling after the devastation of two world wars and the massive spending of the United Kingdom's gold reserves. Despite all links to gold being severed in 1971, the dollar continues to be the world's foremost reserve currency. Furthermore, the Bretton Woods Agreement also set up the global post-war monetary system by setting up rules, institutions and procedures for conducting international trade and accessing the global capital markets using the US dollar.
The financial crisis in Russia in 2014–2016 was the result of the sharp devaluation of the Russian rouble beginning in the second half of 2014. A decline in confidence in the Russian economy caused investors to sell off their Russian assets, which led to a decline in the value of the Russian rouble and sparked fears of a financial crisis. The lack of confidence in the Russian economy stemmed from at least two major sources. The first is the fall in the price of oil in 2014. Crude oil, a major export of Russia, declined in price by nearly 50% between its yearly high in June 2014 and 16 December 2014. The second is the result of international economic sanctions imposed on Russia following Russia's annexation of Crimea, the war in Donbas and the broader Russo-Ukrainian War.
