{{Politics of the European Union}}

The '''euro''' ([[currency symbol|symbol]]: '''[[euro sign|€]]'''; [[ISO 4217|currency code]]: '''EUR''') is the official [[currency]] of 20 of the {{EUnum}} [[Member state of the European Union|member states]] of the [[European Union]]. This group of states is officially known as the euro area or, more commonly, the [[eurozone]]. The euro is divided into 100 [[1 euro cent coin|euro cents]].<ref name="EC Euro Area">{{cite web |url=http://ec.europa.eu/economy_finance/euro/index_en.htm |title=The euro |access-date=2 January 2019 |work=[[European Commission]] website}}</ref><ref name="EC Euro1 euro cent coin Area 2">{{cite web |access-date=2019-01-02 |title=What is the euro area? |url=https://ec.europa.eu/info/business-economy-euro/euro-area/what-euro-area_en |website=European Commission website}}</ref>

The currency is also used officially by the [[institutions of the European Union]], by [[International status and usage of the euro|four European microstates]] that are not EU members,<ref name="EC Euro1 euro cent coin Area 2" /> and the [[British Overseas Territory]] of [[Akrotiri and Dhekelia]], as well as unilaterally by [[Montenegro]] and [[Kosovo]]. Outside Europe, a number of [[special territories of EU members]] also use the euro as their currency.  

The euro is used by 350 million people in Europe, and over 200&nbsp;million people worldwide use [[currencies pegged to the euro]].<ref name="population_jan_2023">{{cite web|url=https://ec.europa.eu/eurostat/databrowser/view/tps00001/default/table?lang=en |title = Population on 1 January|publisher=[[Eurostat]]}}</ref> It is the second-largest [[reserve currency]] as well as the second-most traded currency in the world after the [[United States dollar]].<ref>{{cite web|title=IMF Data – Currency Composition of Official Foreign Exchange Reserve – At a Glance|publisher=International Monetary Fund|url=http://data.imf.org/?sk=E6A5F467-C14B-4AA8-9F6D-5A09EC4E62A4|date=23 December 2022|access-date=11 January 2023}}</ref><ref>{{cite web |title=Foreign exchange turnover in April 2013: preliminary global results |url=http://www.bis.org/publ/rpfx13fx.pdf |publisher=Bank for International Settlements |access-date=7 February 2015}}</ref><ref>{{cite web|url=http://www.bis.org/publ/rpfxf07t.pdf |title=Triennial Central Bank Survey 2007 |publisher=BIS |date=19 December 2007 |access-date=25 July 2009}}</ref><ref>{{cite web |url=http://mpra.ub.uni-muenchen.de/14350/1/MPRA_paper_14350.pdf |last1=Aristovnik |first1=Aleksander |last2=Čeč |first2=Tanja |title=Compositional Analysis of Foreign Currency Reserves in the 1999–2007 Period.

The name ''euro'' was officially adopted on 16 December 1995 in [[Madrid]].<ref name="madrid1995">{{cite web|url=http://www.europarl.europa.eu/summits/mad1_en.htm |title=Madrid European Council (12/95): Conclusions |publisher=European Parliament |access-date=14 February 2009}}</ref> The euro was introduced to world financial markets as an [[unit of account|accounting currency]] on 1 January 1999, replacing the former [[European Currency Unit]] (ECU) at a ratio of 1:1 (US$1.1743 at the time). Physical euro coins and banknotes entered into circulation on 1 January 2002, making it the day-to-day operating currency of its original members, and by March 2002 it had completely replaced the former currencies.<ref>{{cite web| url = http://www.ecb.int/euro/changeover/2002/html/index.en.html| title = Initial changeover (2002)| publisher=European Central Bank| access-date =5 March 2011}}</ref>

Between December 1999 and December 2002, the euro traded below parity with the US dollar, but it has since traded near or above parity with the US dollar. On 13 July 2022, the two currencies briefly hit parity for the first time in nearly two decades, due in part to the [[Economic impact of the Russian invasion of Ukraine|Russian invasion of Ukraine]].<ref name="NYTimes-2022">{{Cite news |date=2022-07-12 |title=Euro Falls Near Parity With Dollar, a Threshold Watched Closely by Investors |work=The New York Times |url=https://www.nytimes.com/2022/07/12/business/euro-dollar-parity.html |access-date=2022-07-13 |issn=0362-4331}}</ref> In the ten years ending 30 September 2025, the rate has averaged at about $1.00:€0.92.<ref>{{cite web |title=US Dollar to Euro Exchange Rate Chart |website=XE.com |url=https://www.xe.com/en-gb/currencycharts/?from=USD&to=EUR&view=10Y |access-date=1 October 2025}}</ref>

[[File:Seat of the European Central Bank and Frankfurt Skyline at dawn 20150422 1.jpg|thumb|260px|Seat of the [[European Central Bank]] in [[Frankfurt]], [[Germany]]]]
The euro is managed and administered by the [[European Central Bank]] and the [[Eurosystem]], composed of the [[central bank]]s of the eurozone countries.<ref>{{cite web |title=The Euro |url=https://www.ecb.europa.eu/euro/html/index.en.html |website=European Central Bank |access-date=2023-10-04}}</ref> As an independent central bank, the ECB has sole authority to set [[monetary policy]].<ref>{{cite web |title=Treaty on the Functioning of the European Union |url=https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A12012E%2FTXT |website=EUR-Lex |access-date=2023-10-04}}</ref> The Eurosystem participates in the printing, minting and distribution of [[euro banknotes]] and [[euro coins|coins]] in all member states,<ref>{{cite web |title=Banknotes and Coins |url=https://www.ecb.europa.eu/euro/notes_coins/html/index.en.html |website=European Central Bank |access-date=2023-10-04}}</ref> and the operation of the eurozone payment systems.<ref>{{cite web |title=Payment Systems |url=https://www.ecb.europa.eu/paym/html/index.en.html |website=European Central Bank |access-date=2023-10-04}}</ref>

Through their ratification of the 1992 [[Maastricht Treaty]] (or subsequent [[Treaty of Accession|treaties of accession]]), most EU member states committed to adopt the euro upon meeting certain monetary and budgetary [[Euro convergence criteria|convergence criteria]], although not all participating states have done so. [[Denmark]] has negotiated exemptions,<ref>{{cite web|title=The Euro |publisher=European Commission|url=http://ec.europa.eu/economy_finance/euro/index_en.htm |access-date=29 January 2009}}</ref> while Sweden (which joined the EU in 1995, after the Maastricht Treaty was signed) turned down the euro in a [[2003 Swedish euro referendum|2003 non-binding referendum]], and has circumvented its commitment to adopt the euro by not meeting the monetary and budgetary requirements. All nations that have joined the EU since 1993 have pledged to adopt the euro in due course. The Maastricht Treaty was amended by the 2001 [[Treaty of Nice]], which closed the gaps and loopholes in the Maastricht and Rome Treaties.<ref>{{cite web |last1=Nice |first1=Treaty of |title=Treaty of Nice |url=https://www.europarl.europa.eu/about-parliament/en/in-the-past/the-parliament-and-the-treaties/treaty-of-nice |website=About Parliament |publisher= European Parliament |access-date=7 May 2021}}</ref>

The euro is divided into 100 [[cent (currency)|cents]] (also referred to as ''euro cents'', especially when distinguishing them from other currencies, and referred to as such on the common side of all cent coins). In Community legislative acts the plural forms of ''euro'' and ''cent'' are spelled without the ''s'', notwithstanding normal English usage.<ref name="ec.europa.eu">{{cite web|url=http://ec.europa.eu/economy_finance/euro/cash/symbol/index_en.htm |title= How to use the euro name and symbol |publisher=European Commission |access-date=7 April 2010}}</ref><ref>{{cite web|url=http://ec.europa.eu/economy_finance/publications/publication6336_en.pdf |title=Spelling of the words "euro" and "cent" in official Community languages as used in Community Legislative acts |access-date=26 November 2008 |author=European Commission }}</ref> Otherwise, normal English plurals are used,<ref>{{cite web |url=http://ec.europa.eu/translation/writing/style_guides/english/style_guide_en.pdf |title=English Style Guide: A handbook for authors and translators in the European Commission |access-date=16 November 2008 |author=European Commission Directorate-General for Translation |url-status=dead |archive-url=https://web.archive.org/web/20101205092625/http://ec.europa.eu/translation/writing/style_guides/english/style_guide_en.pdf |archive-date=5 December 2010 }}; {{cite web |url=http://publications.europa.eu/code/en/en-370303.htm |title=Interinstitutional style guide, 7.3.3.

All circulating coins have a ''common side'' showing the denomination or value and a map in the background. Due to the [[Languages of the European Union|linguistic plurality in the European Union]], the Latin alphabet version of ''euro'' is used (as opposed to the less common Greek or Cyrillic) and [[Arabic numerals]] (other text is used on national sides in national languages, but other text on the common side is avoided). For the denominations except the 1-, 2- and 5-cent coins, the map only showed the 15 member states of the union as of 2002. Beginning in 2007 or 2008 (depending on the country), the old map was replaced by a map of Europe also showing countries outside the [[European Union|EU]].<ref name="europa-common_sides">{{cite web |title=Common sides of euro coins |url=https://economy-finance.ec.europa.eu/euro/euro-coins-and-notes/euro-coins/common-sides-euro-coins_en |website=Europa |publisher=European Commission |access-date=30 December 2023}}</ref> The 1-, 2- and 5-cent coins, however, keep their old design, showing a geographical map of Europe with the [[European Union|EU]] member states as of 2002, raised somewhat above the rest of the map. All common sides were designed by [[Luc Luycx]]. The coins also have a ''national side'' showing an image specifically chosen by the country that issued the coin.

[[€2 commemorative coins|Commemorative coins]] with €2 face value have been issued with changes to the design of the national side of the coin. These include both commonly issued coins, such as the €2 commemorative coin for the fiftieth anniversary of the signing of the Treaty of Rome, and nationally issued coins, such as the coin to commemorate the [[2004 Summer Olympics]] issued by Greece. These coins are legal tender throughout the eurozone. Collector coins with various other denominations have been issued as well, but these are not intended for general circulation, and they are legal tender only in the member state that issued them.<ref>{{cite web|url=http://europa.eu/legislation_summaries/economic_and_monetary_affairs/introducing_euro_practical_aspects/l25058_en.htm |title=Commission communication: The introduction of euro banknotes and coins one year after COM(2002) 747 |access-date=26 January 2009 |author=European Commission |publisher=Europa (web portal) |date=15 February 2003}}</ref>

The design for the [[euro banknotes]] has common designs on both sides. The design was created by the Austrian designer [[Robert Kalina]].<ref name="euro96">{{cite web|url=http://www.ecb.int/euro/changeover/2002/photos/html/image12.en.html |title=Robert Kalina, designer of the euro banknotes, at work at the Oesterreichische Nationalbank in Vienna |publisher=European Central Bank |access-date=30 May 2010}}</ref> Notes are issued in [[500 euro note|€500]], [[200 euro note|€200]], [[100 euro note|€100]], [[50 euro note|€50]], [[20 euro note|€20]], [[10 euro note|€10]], and [[5 euro note|€5]]. Each banknote has its own colour and is dedicated to an artistic period of European architecture. The front of the note features windows or gateways while the back has bridges, symbolising links between states in the union and with the future. While the designs are supposed to be devoid of any identifiable characteristics, the initial designs by Robert Kalina were of specific bridges, including the [[Rialto]] and the [[Pont de Neuilly]], and were subsequently rendered more generic; the final designs still bear very close similarities to their specific prototypes; thus they are not truly generic. The monuments looked similar enough to different national monuments to please everyone.<ref>{{cite news|last=Schmid |first=John |url=https://www.nytimes.com/2001/08/03/news/03iht-euro_ed3_.html |title=Etching the Notes of a New European Identity|work=International Herald Tribune |date=3 August 2001 |access-date=29 May 2009}}</ref>

In December 2021, the ECB announced its plans to redesign euro banknotes by 2024. A theme advisory group, made up of one member from each euro area country, was selected to submit theme proposals to the ECB. The proposals will be voted on by the public; a design competition will also be held.<ref>{{cite journal|title=ECB to redesign euro banknotes by 2024 |url=https://www.ecb.europa.eu/press/pr/date/2021/html/ecb.pr211206~a9e0ba2198.en.html |access-date=7 December 2021 |date=6 December 2021|website=European Central Bank}}</ref>

These liabilities carry interest at the main refinancing rate of the ECB. The other 92% of euro banknotes are issued by the NCBs in proportion to their respective shares of the ECB capital key,<ref name="Scheller"/> calculated using national share of European Union (EU) population and national share of EU GDP, equally weighted.<ref>

== History ==
{{Main|History of the euro}}

=== Introduction ===
{{Euro adoption past|group="note"}}

The euro was established by the provisions in the 1992 [[Maastricht Treaty]].<ref>{{cite web |title=Treaty on European Union (Maastricht Treaty) |url=https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A12012M%2FTXT |website=EUR-Lex |access-date=2023-10-04}}</ref><ref>Dyson, K., & Featherstone, K. (1999). *The Road to Maastricht: Negotiating Economic and Monetary Union*. Oxford University Press.</ref> To participate in the currency, member states are meant to meet [[Euro convergence criteria|strict criteria]], such as a budget [[Government budget deficit|deficit]] of less than 3% of their GDP, a debt ratio of less than 60% of GDP (both of which were ultimately widely flouted after introduction), low inflation, and [[interest]] rates close to the EU average.<ref>{{cite web |title=Convergence Criteria |url=https://www.ecb.europa.eu/euro/html/index.en.html |website=European Central Bank |access-date=2023-10-04}}</ref><ref>Buti, M., & Sapir, A. (2002). *EMU and Economic Policy in Europe: The Challenge of the Early Years*. Edward Elgar Publishing.</ref> In the Maastricht Treaty, the United Kingdom and Denmark were granted exemptions per their request from moving to the stage of monetary union which resulted in the introduction of the euro (see also [[United Kingdom and the euro]]).<ref>{{cite web |title=Protocol on certain provisions relating to the United Kingdom of Great Britain and Northern Ireland |url=https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A12012M%2FTXT |website=EUR-Lex |access-date=2023-10-04}}</ref><ref>George, S. (1998). *An Awkward Partner: Britain in the European Community* (3rd ed.). Oxford University Press.</ref>


The name "euro" was officially adopted in [[Madrid]] on 16 December 1995.<ref name="madrid1995"/> Belgian [[Esperantist]] [[Germain Pirlot]], a former teacher of French and history, is credited with naming the new currency by sending a letter to then [[President of the European Commission]], [[Jacques Santer]], suggesting the name "euro" on 4 August 1995.<ref>{{Cite news | title= Germain Pirlot 'uitvinder' van de euro | url= http://www.ikso.net/vikipedio/artikeleuro.jpg | publisher= De Zeewacht | language= nl | date= 16 February 2007 | access-date= 21 May 2012 | url-status=dead | archive-url= https://web.archive.org/web/20130630181850/http://www.ikso.net/vikipedio/artikeleuro.jpg | archive-date= 30 June 2013 }}</ref>

Due to differences in national conventions for [[rounding]] and significant digits, all conversion between the national currencies had to be carried out using the process of [[Triangulation (finance)|triangulation]] via the euro.<ref>{{Cite news |title=Unready for blast-off |url=https://www.economist.com/unknown/1998/11/05/unready-for-blast-off |access-date=2025-08-28 |newspaper=The Economist |issn=0013-0613}}</ref> The ''definitive'' values of one euro in terms of the [[exchange rate]]s at which the currency entered the euro are shown in the table.

The rates were determined by the [[Council of the European Union]],{{efn|by means of Council Regulation 2866/98 (EC) of 31 December 1998.}} based on a recommendation from the European Commission based on the market rates on 31 December 1998. They were set so that one [[European Currency Unit]] (ECU) would equal one euro. The European Currency Unit was an accounting unit used by the EU, based on the currencies of the member states; it was not a currency in its own right. They could not be set earlier, because the ECU depended on the closing exchange rate of the non-euro currencies (principally [[pound sterling]]) that day.

The procedure used to fix the conversion rate between the [[Modern drachma|Greek drachma]] and the euro was different since the euro by then was already two years old. While the conversion rates for the initial eleven currencies were determined only hours before the euro was introduced, the conversion rate for the Greek drachma was fixed several months beforehand.{{efn|by Council Regulation 1478/2000 (EC) of 19 June 2000.}}

The currency was introduced in non-physical form ([[traveller's cheque]]s, electronic transfers, banking, etc.) at midnight on 1 January 1999, when the national currencies of participating countries (the eurozone) ceased to exist independently. Their exchange rates were locked at fixed rates against each other. The euro thus became the successor to the [[European Currency Unit]] (ECU). The notes and coins for the old currencies, however, continued to be used as [[legal tender]] until new euro notes and coins were introduced on 1 January 2002.

The changeover period during which the former currencies' notes and coins were exchanged for those of the euro lasted about two months, until 28 February 2002. The official date on which the national currencies ceased to be legal tender varied from member state to member state. The earliest date was in Germany, where the [[Deutsche Mark|mark]] officially ceased to be legal tender on 31 December 2001, though the exchange period lasted for two months more. Even after the old currencies ceased to be legal tender, they continued to be accepted by national central banks for periods ranging from several years to indefinitely (the latter for Austria, Germany, Ireland, Estonia and Latvia in banknotes and coins, and for Belgium, Luxembourg, Slovenia and Slovakia in banknotes only). The earliest coins to become non-convertible were the Portuguese [[Portuguese escudo|escudos]], which ceased to have monetary value after 31 December 2002, although banknotes remained exchangeable until 2022.{{clear}}

=== Currency sign ===
{{Main|Euro sign}}
[[File:Euro Construction.svg|thumb|right|Graphic construction of the euro logo]]

A special [[euro sign|euro currency sign]] (€) was designed after a public survey had narrowed ten of the original thirty proposals down to two. The [[President of the European Commission]] at the time ([[Jacques Santer]]) and the European Commissioner with responsibility for the euro ([[Yves-Thibault de Silguy]]) then chose the winning design.<ref>{{cite web |title=The euro, our currency {{!}} A symbol for the European currency |date=18 March 2009  |access-date=8 April 2023 |publisher=European Commission |url=https://ec.europa.eu/economy_finance/events/2009/theeuro/isola3_en2008-2009.pdf}}</ref>

Regarding the symbol, the [[European Commission]] stated on behalf of the [[European Union]]:

{{blockquote|The symbol € is based on the Greek letter epsilon (Є), with the first letter in the word "Europe" and with 2 parallel lines signifying stability.|source=[[Directorate-General for Communication]]<ref name="design, rules">{{cite web |title=Institutions, law, budget {{!}} The Euro {{!}} Design |author=Directorate-General for Communication |publisher=European Union |access-date=8 April 2022 |url= https://european-union.europa.eu/institutions-law-budget/euro/design_en}}</ref>}}

The European Commission also specified a euro logo with exact proportions.<ref name="design, rules" /> Placement of the currency sign relative to the numeric amount varies from state to state, but for texts in English published by EU institutions, the symbol (or the [[International Organization for Standardization|ISO]]-standard "EUR") should precede the amount.<ref>{{cite web|url=http://publications.europa.eu/code/en/en-370303.htm#position|title=Position of the ISO code or euro sign in amounts|date=5 February 2009|work=Interinstitutional style guide|publisher=Europa Publications Office|access-date=10 January 2010|location=Bruxelles, Belgium}}</ref>

According to the [[Economist Intelligence Unit]] in 2011, "[I]f the [euro area] is treated as a single entity, its [economic and fiscal] position looks no worse and in some respects, rather better than that of the US or the UK" and the budget deficit for the euro area as a whole is much lower and the euro area's government debt/GDP ratio of 86% in 2010 was about the same level as that of the United States. "Moreover", they write, "private-sector indebtedness across the euro area as a whole is markedly lower than in the highly leveraged [[Anglosphere|Anglo-Saxon]] economies". The authors conclude that the crisis "is as much political as economic" and the result of the fact that the euro area lacks the support of "institutional [[paraphernalia]] (and mutual bonds of solidarity) of a state".<ref>{{cite web|url=http://pages.eiu.com/rs/eiu2/images/EuroDebtPaperMarch2011.pdf |title=State of the Union: Can the euro zone survive its debt crisis?|page=4 |publisher=[[Economist Intelligence Unit]] |date=1 March 2011 |access-date=1 December 2011}}</ref>

Outside the eurozone, two EU member states have currencies that are [[Fixed exchange rate system|pegged to the euro]], which is a precondition to joining the eurozone. The [[Danish krone]] and [[Bulgarian lev]] are pegged through to their participation in the [[European Exchange Rate Mechanism|ERM&nbsp;II]].

On the other hand, the currencies of countries and territories that were pegged to the European currencies that disappeared with the creation of the euro were now pegged to it. Currently, they are as follows:
* [[Bosnia and Herzegovina]]: The [[Bosnia and Herzegovina convertible mark]] was pegged to the [[Deutsche mark]]. Currently, it has a fixed exchange rate of 1.95583 convertible marks = 1 euro.
* [[Cape Verde]]: The [[Cape Verdean escudo]] was pegged to the [[Portuguese escudo]]. Currently, it has a fixed exchange rate of 110.625 Cape Verdean escudos = 1 euro.
* [[Comoros]]: The [[Comorian franc]] was pegged to the [[French franc]]. Currently, it has a fixed exchange rate of 491.96775 Comorian francs = 1 euro.
* [[Economic and Monetary Community of Central Africa]] ([[Cameroon]], the [[Central African Republic]], [[Chad]], [[Equatorial Guinea]], [[Gabon]] and the [[Republic of the Congo]]): the [[Central African CFA franc]] was pegged to the [[French franc]]. It currently has a fixed exchange rate of 655.957 Central African CFA francs = 1 euro.
* [[North Macedonia]]: The [[Macedonian denar]] was pegged to the [[Deutsche mark]]. It is currently pegged to the euro. Its exchange rate remains stable at around 61 Macedonian denars to 1 euro.
* [[West African Economic and Monetary Union]] ([[Benin]], [[Burkina Faso]], [[Guinea-Bissau]], [[Ivory Coast]], [[Mali]], [[Niger]], [[Senegal]], and [[Togo]]): The [[West African CFA franc]] was pegged to the [[French franc]]. It currently has a fixed exchange rate of 655.957 West African CFA francs = 1 euro.
* The [[overseas collectivity|French overseas collectivities]] of [[French Polynesia]] and [[Wallis and Futuna]] as well as the special collectivity of [[New Caledonia]]: the [[CFP franc]] was pegged to the [[French franc]]. It currently has a fixed exchange rate of 1000 CFP francs = 8.38 euros, which makes 119.331742 CFP francs ≈ 1 euro.

Furthermore, the currency of [[São Tomé and Príncipe]] (the [[São Tomé and Príncipe dobra]]) is pegged to the euro following an agreement signed with Portugal in 2009 and which came into effect on 1 January 2010.<ref>{{cite web|url=http://www.telanon.info/economia/2010/01/04/2437/1-euro-equivale-a-24500-dobras/|title=1 euro equivale a 24.500 dobras|date=4 January 2009|trans-title=1 euro is equivalent to 24,500 dobras|language=pt|access-date=16 November 2020|publisher=Téla Nón}}</ref> It has a fixed exchange rate of 24.5 São Tomé and Príncipe dobras = 1 euro.

Of the currencies mentioned, the [[Bosnia and Herzegovina convertible mark]] maintains a fixed exchange rate through the [[currency board]] system; the [[Central African CFA franc]], the [[West African CFA franc]], the [[CFP franc]], the [[Cape Verdean escudo]], the [[Comorian franc]], and the [[São Tomé and Príncipe dobra]] maintain a conventional fixed exchange rate; and the [[Macedonian denar]] uses a stabilized arrangement. Additionally, the currency of [[Morocco]], the [[Moroccan dirham]], is pegged to the euro through a [[basket of currencies]]. Other countries that, as of December 2023, have exchange rate regimes linked to the euro are [[Romania]], [[Serbia]], [[Singapore]], [[Botswana]], [[Tunisia]], [[Samoa]], [[Fiji]], [[Libya]], [[Kuwait]], [[Syria]], [[China]] and [[Vanuatu]].<ref>{{cite web |url=https://www.elibrary.imf.org/downloadpdf/display/book/9798400260391/9798400260391.pdf |title=Annual report on exchange arrangements and exchange restrictions, 2023}}</ref><ref>{{cite web |url=https://www.ecb.europa.eu/pub/pdf/ire/ecb.ire202406_annex.en.pdf |title=The euro in global foreign exchange reserves and exchange rate anchoring}}</ref><ref>{{cite web |url=https://www.imf.org/-/media/Files/Publications/CR/2025/English/1mkdea2025001-print-pdf.ashx |title=INTERNATIONAL MONETARY FUND.

Pegging a country's currency to a major currency is regarded as a safety measure, especially for currencies of areas with weak economies, as the euro is seen as a stable currency, prevents runaway inflation, and encourages foreign investment due to its stability.

In total, {{As of|2013|lc=y}}, 182&nbsp;million people in Africa use a currency pegged to the euro, 27&nbsp;million people outside the eurozone in Europe, and another 545,000 people on Pacific islands.<ref name="2013_data_sheet"/>

Since 2005, stamps issued by the [[Sovereign Military Order of Malta]] have been denominated in euros, although the Order's official currency remains the [[Maltese scudo]].<ref name=smom>{{cite web| url = https://www.orderofmalta.int/associate-countries/| title = Retrieved 3 October 2017.}}</ref> The Maltese scudo itself is pegged to the euro and is only recognised as legal tender within the Order.

=== Use as reserve currency ===
Since its introduction in 1999, the euro has been the second most widely held international [[reserve currency]] after the U.S. dollar. The share of the euro as a reserve currency increased from 18% in 1999 to 27% in 2008. Over this period, the share held in U.S. dollar fell from 71% to 64% and that held in RMB fell from 6.4% to 3.3%. The euro inherited and built on the status of the [[Deutsche Mark]] as the second most important reserve currency. The euro remains underweight as a reserve currency in advanced economies while overweight in emerging and developing economies: according to the [[International Monetary Fund]]<ref name="external1">{{cite web|url=http://www.imf.org/external/np/sta/cofer/eng/cofer.pdf |title=Currency Composition of Official Foreign Exchange Reserves (COFER)&nbsp;– Updated COFER tables include first quarter 2009 data. June&nbsp;30, 2009 |access-date=8 July 2009}}</ref> the total of euro held as a reserve in the world at the end of 2008 was equal to $1.1&nbsp;trillion or €850&nbsp;billion, with a share of 22% of all currency reserves in advanced economies, but a total of 31% of all currency reserves in emerging and developing economies.

The possibility of the euro becoming the first international reserve currency has been debated among economists.<ref>{{cite web |url=http://www.wage.wisc.edu/uploads/Working%20Papers/chinnfrankel_NBER_eurotopcurrency.pdf |title=Will the Euro Eventually Surpass the Dollar As Leading International Reserve Currency? |access-date=17 July 2011 |url-status=dead |archive-url=https://web.archive.org/web/20130825070016/http://www.wage.wisc.edu/uploads/Working%20Papers/chinnfrankel_NBER_eurotopcurrency.pdf |archive-date=25 August 2013 }}</ref> Former [[Federal Reserve]] Chairman [[Alan Greenspan]] gave his opinion in September 2007 that it was "absolutely conceivable that the euro will replace the US dollar as reserve currency, or will be traded as an equally important reserve currency".<ref>{{Cite news| title=Euro could replace dollar as top currency&nbsp;– Greenspan | url=https://www.reuters.com/article/bondsNews/idUSL1771147920070917 | access-date=17 September 2007 | date=17 September 2007 |work=Reuters}}</ref> In contrast to Greenspan's 2007 assessment, the euro's increase in the share of the worldwide currency reserve basket has slowed considerably since 2007 and since the beginning of the [[Great Recession]] and [[Euro area crisis]].<ref name="external1"/>

=== Optimal currency area ===
{{Further|Optimum currency area}}

In economics, an optimum currency area, or region (OCA or OCR), is a geographical region in which it would maximise economic efficiency to have the entire region share a single currency. There are two models, both proposed by [[Robert Mundell]]: the [[Optimum currency area#OCA with stationary expectations|stationary expectations model]] and the [[Optimum currency area#OCA with international risk sharing|international risk sharing model]]. Mundell himself advocates the international risk sharing model and thus concludes in favour of the euro.<ref>{{cite book|chapter=A Plan for a European Currency |date=1970 |orig-year=published 1973|last=Mundell |first=Robert|editor1=Johnson, H. G. | editor2= Swoboda, A. K. | title = The Economics of Common Currencies{{snd}} Proceedings of Conference on Optimum Currency Areas. 1970. Madrid. | publisher= Allen and Unwin | location = London |pages= 143–172 | isbn= 9780043320495}}</ref> However, even before the creation of the single currency, there were concerns over diverging economies. Before the [[late-2000s recession]] it was considered unlikely that a state would leave the euro or the whole zone would collapse.<ref>{{cite journal |ssrn=1014341 |title=The Breakup of the Euro Area by Barry Eichengreen |date=14 September 2007 |journal=[[NBER Working Paper]] |number=w13393|last1=Eichengreen |first1=Barry }}</ref> However the [[Greek government-debt crisis]] led to former [[British Foreign Secretary]] [[Jack Straw]] claiming the eurozone could not last in its current form.<ref>{{cite news|url=https://www.bbc.co.uk/news/uk-politics-13839381 |title=Greek debt crisis: Straw says eurozone 'will collapse' |work=[[BBC News]] |date=20 June 2011 |access-date=17 July 2011}}</ref> Part of the problem seems to be the rules that were created when the euro was set up. John Lanchester, writing for ''[[The New Yorker]]'', explains it: {{blockquote|The guiding principle of the currency, which opened for business in 1999, were supposed to be a set of rules to limit a country's annual deficit to three per cent of gross domestic product, and the total accumulated debt to sixty per cent of G.D.P. It was a nice idea, but by 2004 the two biggest economies in the euro zone, Germany and France, had broken the rules for three years in a row.<ref>John Lanchester, "Euro Science", ''The New Yorker'', 10 October 2011.</ref>}}

Increasing business cycle divergence across the Eurozone over the last decades implies a decreasing optimum currency area.<ref>{{cite journal | doi=10.1007/s11079-024-09750-z | title=Optimum Currency Area in the Eurozone | date=2024 | last1=Beck | first1=Krzysztof | last2=Okhrimenko | first2=Iana | journal=Open Economies Review | volume=36 | pages=197–219 | doi-access=free  |issn = 0923-7992 }}</ref>

=== Transaction costs and risks ===

The most obvious benefit of adopting a single currency is to remove the cost of exchanging currency, theoretically allowing businesses and individuals to consummate previously unprofitable trades. For consumers, banks in the eurozone must charge the same for intra-member cross-border transactions as purely domestic transactions for electronic payments (e.g., [[credit card]]s, [[debit card]]s and [[cash machine]] withdrawals).

Financial markets on the continent are expected to be far more [[market liquidity|liquid]] and flexible than they were in the past. The reduction in cross-border transaction costs will allow larger banking firms to provide a wider array of banking services that can compete across and beyond the eurozone. However, although transaction costs were reduced, some studies have shown that [[risk aversion]] has increased during the last 40 years in the Eurozone.<ref>Benchimol, J., 2014. [https://ideas.repec.org/a/eee/reecon/v68y2014i1p39-56.html Risk aversion in the Eurozone], [[Research in Economics]], vol. 68, issue 1, pp. 40–56.</ref>

=== Price parity ===

Another effect of the common European currency is that differences in prices—in particular in price levels—should decrease because of the [[law of one price]]. Differences in prices can trigger [[arbitrage]], i.e., [[speculation|speculative]] trade in a [[commodity]] across borders purely to exploit the price differential. Therefore, prices on commonly traded goods are likely to converge, causing inflation in some regions and deflation in others during the transition. Some evidence of this has been observed in specific eurozone markets.<ref>{{cite journal |first1=Pinelopi K. |last1=Goldberg |first2=Frank |last2=Verboven |title=Market Integration and Convergence to the Law of One Price: Evidence from the European Car Market |journal=Journal of International Economics |volume=65 |issue=1 |year=2005 |pages=49–73 |doi=10.1016/j.jinteco.2003.12.002 |citeseerx=10.1.1.494.1517 |s2cid=26850030 }}</ref>

=== Macroeconomic stability ===

Before the introduction of the euro, some countries had successfully contained inflation, which was then seen as a major economic problem, by establishing largely independent central banks. One such bank was the [[Bundesbank]] in Germany; the European Central Bank was modelled on the Bundesbank.<ref name="bundesbank">{{Cite book|title=The History of the Bundesbank: Lessons for the European Central Bank |last=de Haan |first=Jakob |year=2000 |publisher=Routledge |location=London |isbn=978-0-415-21723-1 |url=https://books.google.com/books?id=EaIV0OWlaokC}}</ref>

The euro has come under criticism due to its regulation, lack of flexibility and rigidity towards sharing member states on issues such as nominal interest rates.<ref>{{Cite journal|last=Silvia|first=Steven J|year=2004|title=Is the Euro Working? The Euro and European Labour Markets|jstor=4007858|volume=24|issue=2|pages=147–168|doi=10.1017/s0143814x0400008x|journal=Journal of Public Policy|s2cid=152633940}}</ref>
Many national and corporate [[bond (finance)|bonds]] denominated in euro are significantly more liquid and have lower interest rates than was historically the case when denominated in national currencies. While increased liquidity may lower the [[nominal interest rate]] on the bond, denominating the bond in a currency with low levels of inflation arguably plays a much larger role. A credible commitment to low levels of inflation and a stable debt reduces the risk that the value of the debt will be eroded by higher levels of inflation or default in the future, allowing debt to be issued at a lower nominal interest rate.

There is also a cost in structurally keeping inflation lower than in the United States, United Kingdom, and China. The result is that seen from those countries, the euro has become expensive, making European products increasingly expensive for its largest importers; hence export from the eurozone becomes more difficult.

In general, those in Europe who own large amounts of euro are served by high stability and low inflation.

A [[monetary union]] means states in that union lose the main mechanism of recovery of their international [[Competition (companies)|competitiveness]] by weakening ([[Currency appreciation and depreciation|depreciating]]) their currency. When [[wage]]s become too high compared to [[productivity]] in the exports sector, then these exports become more expensive and they are crowded out from the market within a country and abroad. This drives the fall of employment and output in the exports sector and fall of [[Balance of trade|trade]] and [[Current account (balance of payments)|current account]] balances. Fall of output and employment in the tradable goods sector may be offset by the growth of non-exports sectors, especially in [[construction]] and [[Service (economics)|services]]. Increased purchases abroad and negative current account balances can be financed without a problem as long as [[credit]] is cheap.<ref>{{cite web |author1=Ernest Pytlarczyk, Stefan Kawalec |title=Controlled Dismantlement of the Euro Area in Order to Preserve the European Union and Single European Market |url=http://www.case-research.eu/en/controlled-dismantlement-of-the-euro-area-in-order-to-preserve-the-european-union-and-sing |publisher=CASE Center for Social and Economic Research |access-date=19 December 2018 |pages=11 |date=June 2012}}</ref> The need to finance trade deficit weakens currency, making exports automatically more attractive in a country and abroad. A state in a monetary union cannot use weakening of currency to recover its international competitiveness. To achieve this a state has to reduce prices, including wages ([[deflation]]). This could result in high [[unemployment]] and lower incomes as it was during the [[euro area crisis]].<ref>{{cite journal |author1=[[Martin Feldstein]] |title=The Failure of the Euro |journal=Foreign Affairs |date=January–February 2012 |url=https://www.nber.org/feldstein/fa121311.html |at=Chapter: Trading Places}}</ref>

==== Inflation ====
[[File:Euro inflation.webp|thumb|Euro Zone inflation]]
The introduction of the euro has led to extensive discussion about its possible effect on inflation. In the short term, there was a widespread impression in the population of the eurozone that the introduction of the euro had led to an increase in prices, but this impression was not confirmed by general indices of inflation and other studies.<ref>{{Cite journal|author = Paolo Angelini |author2=Francesco Lippi | title = Did Prices Really Soar after the Euro Cash Changeover?

==== Exchange rate risk ====
One of the advantages of the adoption of a common currency is the reduction of the risk associated with changes in currency exchange rates.<ref name="Eichengreen-2019"/> It has been found that the introduction of the euro created "significant reductions in market risk exposures for nonfinancial firms both in and outside Europe".<ref>{{cite journal |title=The impact of the introduction of the Euro on foreign exchange rate risk exposures |journal=Journal of Empirical Finance |doi=10.1016/j.jempfin.2006.01.002 |volume=13 |issue=4–5 |pages=519–549|year=2006 |last1=Bartram |first1=Söhnke M. |last2=Karolyi |first2=G. Andrew }}</ref> These reductions in market risk "were concentrated in firms domiciled in the eurozone and in non-euro firms with a high fraction of foreign sales or assets in Europe".

==== Financial integration ====
The introduction of the euro increased financial integration within Europe, which helped stimulate growth of a European [[securities market]] (bond markets are characterized by [[economies of scale]] dynamics).<ref name="Eichengreen-2019"/> According to a study on this question, it has "significantly reshaped the European financial system, especially with respect to the securities markets [...] However, the real and policy barriers to integration in the retail and corporate banking sectors remain significant, even if the wholesale end of banking has been largely integrated."<ref>{{cite web|url=http://www.tcd.ie/iiis/documents/discussion/pdfs/iiisdp139.pdf |title=The Euro and Financial Integration|date=May 2006 |access-date=2 October 2009}}</ref> Specifically, the euro has significantly decreased the cost of trade in bonds, equity, and banking assets within the eurozone.<ref>{{cite journal |title=The geography of asset trade and the euro: Insiders and outsiders |journal=Journal of the Japanese and International Economies |doi=10.1016/j.jjie.2008.11.001 |volume=23 |issue=2 |pages=90–113|year=2009 |last1=Coeurdacier |first1=Nicolas |last2=Martin |first2=Philippe |s2cid=55948853 |url=http://www.cepremap.fr/depot/docweb/docweb0701.pdf }}</ref> On a global level, there is evidence that the introduction of the euro has led to an integration in terms of investment in bond portfolios, with eurozone countries lending and borrowing more between each other than with other countries.<ref>{{cite journal |last1=Lane |first1=Philip R. |title=Global Bond Portfolios and EMU |journal=International Journal of Central Banking |date=June 2006 |volume=2 |issue=2 |pages=1–23 |url=https://www.ijcb.org/journal/ijcb06q2a1.htm |citeseerx=10.1.1.365.4579 }}</ref> Financial integration made it cheaper for European companies to borrow.<ref name="Eichengreen-2019"/> Banks, firms and households could also invest more easily outside of their own country, thus creating greater international risk-sharing.<ref name="Eichengreen-2019"/>

==== Effect on interest rates ====
[[File:Long-term interest rates of eurozone countries since 1993.png|thumb|upright=1.35|Secondary market yields of government bonds with maturities of close to 10 years]]

As of January 2014, and since the introduction of the euro, interest rates of most member countries (particularly those with a weak currency) have decreased. Some of these countries had the most serious sovereign financing problems.

The effect of declining interest rates, combined with excess liquidity continually provided by the ECB, made it easier for banks within the countries in which interest rates fell the most, and their linked sovereigns, to borrow significant amounts (above the 3% of GDP budget deficit imposed on the eurozone initially) and significantly inflate their public and private debt levels.<ref>{{cite web|url=http://www.investmentweek.co.uk/investment-week/opinion/2076100/redwood-origins-euro-crisis |title=Redwood: The origins of the euro crisis |publisher=Investmentweek.co.uk |date=3 June 2011 |access-date=16 September 2011}}</ref> Following the [[2008 financial crisis]], governments in these countries found it necessary to bail out or nationalise their privately held banks to prevent systemic failure of the banking system when underlying hard or financial asset values were found to be grossly inflated and sometimes so nearly worthless there was no liquid market for them.<ref>{{cite web|url=http://www.ip-global.org/2011/02/01/farewell-fair-weather-euro/ |title=Farewell, Fair-Weather Euro &#124; IP&nbsp;– Global-Edition |publisher=Ip-global.org |access-date=16 September 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110317161013/http://www.ip-global.org/2011/02/01/farewell-fair-weather-euro/ |archive-date=17 March 2011 }}</ref> This further increased the already high levels of public debt to a level the markets began to consider unsustainable, via increasing government bond interest rates, leading to the [[euro area crisis]].

==== Price convergence ====
The evidence on the convergence of prices in the eurozone with the introduction of the euro is mixed. Several studies failed to find any evidence of convergence following the introduction of the euro after a phase of convergence in the early 1990s.<ref>{{cite web |url=https://www.ecb.eu/events/pdf/conferences/emu/sessionV_Angeloni_Paper.pdf |title=Price setting and inflation dynamics: did EMU matter |access-date=13 March 2011 |archive-url=https://web.archive.org/web/20110725112443/http://www.ecb.eu/events/pdf/conferences/emu/sessionV_Angeloni_Paper.pdf |archive-date=25 July 2011 |url-status=dead }}</ref><ref>{{cite web|url=http://opus.zbw-kiel.de/volltexte/2009/7575/pdf/200906dkp.pdf |title=Price convergence in the EMU?

==== Tourism ====
A study suggests that the introduction of the euro has had a positive effect on the amount of tourist travel within the EMU, with an increase of 6.5%.<ref>{{cite journal|last1=Gil-Pareja|first1=Salvador|last2=Llorca-Vivero|first2=Rafael|last3=Martínez-Serrano|first3=José|title=The Effect of EMU on Tourism|ssrn=983231|journal=Review of International Economics |volume=15 |issue=2 |pages=302–312 |date=May 2007|doi=10.1111/j.1467-9396.2006.00620.x|s2cid=154503069}}</ref>

== Exchange rates ==
=== Flexible exchange rates ===

The ECB targets [[interest rate]]s rather than [[exchange rate]]s and in general, does not intervene on the foreign exchange rate markets. This is because of the implications of the [[Mundell–Fleming model]], which implies a central bank cannot (without [[capital control]]s) maintain interest rate and exchange rate targets simultaneously, because increasing the [[money supply]] results in a [[Currency appreciation and depreciation|depreciation]] of the currency. In the years following the [[Single European Act]], the EU has liberalised its capital markets and, as the ECB has [[inflation targeting]] as its [[monetary policy]], the exchange-rate regime of the euro is [[floating exchange rate|floating]].

=== Against other major currencies ===

The euro is the second-most widely held [[reserve currency]] after the U.S. dollar. After its introduction on 4 January 1999 its exchange rate against the other major currencies fell reaching its lowest exchange rates in 2000 (3 May vs [[Pound sterling|sterling]], 25 October vs the [[U.S. dollar]], 26 October vs [[Japanese yen]]). Afterwards it regained and its exchange rate reached its historical highest point in 2008 (15 July vs US dollar, 23 July vs Japanese yen, 29 December vs sterling). With the onset of the [[2008 financial crisis]], the euro initially fell, to regain later. Despite pressure due to the [[euro area crisis]], the euro remained stable.<ref>{{cite news |last1=Kirschbaum |first1=Erik |title=Schaeuble says markets have confidence in euro |work=Reuters |url=https://www.reuters.com/article/us-eurozone-schaeuble/schaeuble-says-markets-have-confidence-in-euro-idUSTRE77L0LK20110822 |access-date=28 March 2018}}</ref> In November 2011 the euro's exchange rate index&nbsp;– measured against currencies of the bloc's major trading partners&nbsp;– was trading almost two percent higher on the year, approximately at the same level as it was before the crisis began in 2007.<ref>{{cite news |url=http://uk.reuters.com/article/uk-markets-euro-mystery-idUKLNE7AE02520111115 |archive-url=https://web.archive.org/web/20151230043335/http://uk.reuters.com/article/uk-markets-euro-mystery-idUKLNE7AE02520111115 |url-status=dead |archive-date=30 December 2015 |title= Puzzle over euro's 'mysterious' stability |work=[[Reuters]] |date= 15 November 2011}}</ref> In mid July 2022, the euro and the US dollar traded at par for a short period of time during an episode of dollar [[Currency appreciation and depreciation|appreciation]].<ref name="NYTimes-2022" /> On 8 October 2025, it recorded a new high against the Japanese yen during a long period of [[Currency appreciation and depreciation|depreciation]] of the latter.<ref>{{Cite journal |title=Japanese yen (JPY) |url=https://www.ecb.europa.eu/stats/policy_and_exchange_rates/euro_reference_exchange_rates/html/eurofxref-graph-jpy.en.html |access-date=2025-10-17 |website=www.ecb.europa.eu}}</ref>

== Political considerations ==
Besides the economic motivations to the introduction of the euro, its creation was also partly justified as a way to foster a closer sense of joint identity between European citizens. Statements about this goal were for instance made by [[Wim Duisenberg]], European Central Bank Governor, in 1998,<ref>{{cite book |title=Global Finance After the Crisis|date= 2013|quote=The euro is far more than a medium of exchange.

== ''Euro'' in various official EU languages ==
{{Main|Language and the euro}}
The formal titles of the currency are ''euro'' for the major unit and ''cent'' for the minor (one-hundredth) unit and for official use in most eurozone languages; according to the ECB, all languages should use the same spelling for the nominative singular.<ref>{{cite web|url=http://www.ecb.int/pub/pdf/conrep/cr200705en.pdf|title=European Central Bank, Convergence Report|date= May 2007|quote=The euro is the single currency of the member states that have adopted it.
