A '''reserve currency''' is a [[foreign currency]] that is held in significant quantities by [[central bank]]s or other [[monetary authority|monetary authorities]] as part of their [[foreign exchange reserves]].{{cn|date=January 2025}} 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]].

The United Kingdom's [[pound sterling]] was the primary reserve currency of much of the world in the 19th century and the first half of the 20th century.<ref name=Schenk_2009/> However, by the middle of the 20th century, the [[United States dollar]] had become the world's dominant reserve currency.<ref>[http://www.federalreserve.gov/pf/pdf/pf_4.pdf "The Federal Reserve in the International Sphere"], ''The Federal Reserve System: Purposes & Functions'', a publication of the Board of Governors of the Federal Reserve System, 9th Edition, June 2005</ref>

==History==
Reserve currencies have come and gone with the evolution of the world’s geopolitical order. International currencies in the past have (in addition to those discussed below) included the [[Ancient drachma|Greek drachma]], coined in the fifth century BC, the Roman [[denarius]], the Byzantine [[Solidus (coin)|solidus]], the Islamic [[Gold dinar|dinar]] of the Middle Ages, and the [[French franc]].

The Venetian [[ducat]] and the Florentine [[florin]] was the gold-based currency of choice between Europe and the Arab world from the 13th to the 16th centuries, since gold was easier than silver to mint in standard sizes and transport over long distances. It was the [[Spanish dollar|Spanish silver dollar]], however, which created the first true global reserve currency recognized in Europe, Asia and the Americas from the 16th to the 19th centuries due to abundant silver supplies from [[Spanish America]].<ref>{{Cite web|url=https://nationalinterest.org/feature/the-silver-way-explains-how-the-old-mexican-dollar-changed-20410|title = 'The Silver Way' Explains How the Old Mexican Dollar Changed the World|date = 30 April 2017}}</ref>

While the [[Dutch guilder#History|Dutch guilder]] was a reserve currency of somewhat lesser scope, used between Europe and the territories of the [[Dutch colonial empire]] from the 17th to 18th centuries, it was also a [[silver standard]] currency fed with the output of Spanish-American mines flowing through the [[Spanish Netherlands]]. The Dutch, through the ''Amsterdam Wisselbank'' (the [[Bank of Amsterdam]]), were also the first to establish a reserve currency whose monetary unit was stabilized using practices familiar to modern [[central banking]] (as opposed to the [[Spanish dollar]] stabilized through American mine output and Spanish fiat) and which can be considered as the precursor to modern-day [[monetary policy]].<ref>{{Cite web|title=The Big Problem of Large Bills: The Bank of Amsterdam and the Origins of Central Banking |first1=Stephen |last1=Quinn |first2=William |last2=Roberds |publisher=Federal Reserve Bank of Atlanta, Working Paper 2005-16|date=2005 |location=United States of America |url=https://www.frbatlanta.org/-/media/Documents/research/publications/wp/2005/wp0516.pdf?la=en }}</ref><ref name="The Euro at Ten">{{cite book|title=The Euro at Ten: The Next Global Currency |first1=Jean |last1=Pisani-Ferry |first2=Adam S. |last2=Posen |publisher=Peter G.

It was therefore the Dutch which served as the model for [[bank money]] and reserve currencies stabilized by central banks, with the establishment of [[Bank of England]] in 1694 and the [[Bank of France]] in the 18th century. The British [[pound sterling]], in particular, was poised to dislodge the Spanish dollar's hegemony as the rest of the world transitioned to the [[gold standard]] in the last quarter of the 19th century. At that point, the UK was the primary exporter of manufactured goods and services, and over 60% of world trade was invoiced in pounds sterling. British banks were also expanding overseas; London was the world centre for [[insurance]] and [[commodity market]]s and British capital was the leading source of foreign investment around the world; sterling soon became the standard currency used for international commercial transactions.<ref>[https://www.telegraph.co.uk/news/1399693/A-history-of-sterling.html "A history of sterling"] by Kit Dawnay, ''[[The Daily Telegraph|The Telegraph]]'', 8 October 2001</ref> On continental Europe, the bimetallic standard of the [[French franc]] remained the unifying currency of several European countries and their colonies under the [[Latin Monetary Union]], which was established in 1865.

Attempts were made in the [[interwar period]] to restore the gold standard. The British [[Gold Standard Act 1925|Gold Standard Act]] reintroduced the gold bullion standard in 1925,<ref name=winnie>[http://www.winstonchurchill.org/learn/speeches/speeches-of-winston-churchill/115-gold-standard-bill Text of the Gold Standard Bill speech] {{webarchive|url=https://web.archive.org/web/20091002010318/http://www.winstonchurchill.org/learn/speeches/speeches-of-winston-churchill/115-gold-standard-bill |date=2 October 2009 }} by [[Winston Churchill]], [[House of Commons of the United Kingdom|House of Commons]], 4 May 1925</ref> followed by many other countries. This led to relative stability, followed by [[deflation]], but because of the onset of the [[Great Depression]] and other factors, global trade greatly declined and the gold standard fell.

After [[World War II]], the international financial system was governed by a formal agreement, the [[Bretton Woods system]]. Under this system, the [[United States dollar]] (USD) was placed deliberately as the anchor of the system, with the US government guaranteeing other central banks that they could sell their US dollar reserves at a fixed rate for gold.<ref>[http://www.treasury.gov/resource-center/international/exchange-rate-policies/Documents/Appendix%201%20Final%20October%2015%202009.pdf An Historical Perspective on the Reserve Currency Status of the U.S. Dollar] treasury.gov</ref>

In the late 1960s and early 1970s, the system suffered setbacks ostensibly due to problems pointed out by the [[Triffin dilemma]]—the conflict of economic interests that arises between short-term domestic objectives and long-term international objectives when a national currency also serves as a world reserve currency.<ref>{{cite web | url=https://www.moneymetals.com/news/2025/04/09/golds-historic-race-to-reclaim-its-role-as-the-preeminent-reserve-currency-003969 | title=WATCH: Gold's Historic Race to Reclaim Role as Preeminent Reserve Currency }}</ref>

Additionally, in 1971 [[President of the United States|President]] [[Richard Nixon]] [[Nixon shock|suspended the convertibility of the USD to gold]], thus creating a fully [[Fiat money|fiat]] global reserve currency system. However, gold has persisted as a significant reserve asset since the collapse of the classical gold standard.<ref>{{Cite journal|last1=Jabko|first1=Nicolas|last2=Schmidt|first2=Sebastian|date=2022|title=The Long Twilight of Gold: How a Pivotal Practice Persisted in the Assemblage of Money|url=https://www.cambridge.org/core/journals/international-organization/article/abs/long-twilight-of-gold-how-a-pivotal-practice-persisted-in-the-assemblage-of-money/4D6FD92E9BAB8192D207E2A5CBFD87E6|journal=International Organization|volume=76 |issue=3 |pages=625–655|language=en|doi=10.1017/S0020818321000461|s2cid=245413975|issn=0020-8183}}</ref>

Following the [[2020 Economic Recession|2020 economic recession]], the [[International Monetary Fund|IMF]] opined about the emergence of "A New Bretton Woods Moment" which could imply the need for a new global reserve currency system.

==Theory==
Economists debate whether a single reserve currency will always dominate the global economy.<ref>{{cite report|ssrn=723305|title=Sterling's Past, Dollar's Future: Historical Perspectives on Reserve Currency Competition |first=Barry |last=Eichengreen |publisher=National Bureau of Economic Research (NBER) |date=May 2005 }}</ref> Many have recently argued that one currency will almost always dominate due to [[network externalities]] (sometimes called "the network effect"), especially in the field of invoicing trade and denominating foreign debt securities, meaning that there are strong incentives to conform to the choice that dominates the marketplace. The argument is that, in the absence of sufficiently large shocks, a currency that dominates the marketplace will not lose much ground to challengers.

However, some economists, such as [[Barry Eichengreen]], argue that this is not as true when it comes to the denomination of official reserves because the network externalities are not strong. As long as the currency's market is sufficiently liquid, the benefits of reserve diversification are strong, as it insures against large capital losses. The implication is that the world may well soon begin to move away from a financial system dominated uniquely by the US dollar. In the first half of the 20th century, multiple currencies did share the status as primary reserve currencies. Although the British Sterling was the largest currency, both the French franc and the German mark shared large portions of the market until the First World War, after which the mark was replaced by the dollar. Since the Second World War, the dollar has dominated official reserves, but this is likely a reflection of the unusual domination of the American economy during this period, as well as official discouragement of reserve status from the potential rivals, Germany and Japan.

The top reserve currency is generally selected by the banking community for the strength and stability of the economy in which it is used. Thus, as a currency becomes less stable, or its economy becomes less dominant, bankers may over time abandon it for a currency issued by a larger or more stable economy. This can take a relatively long time, as recognition is important in determining a reserve currency. For example, it took many years after the United States overtook the United Kingdom as the world's largest economy before the dollar overtook the pound sterling as the dominant global reserve currency.<ref name=Schenk_2009>"[https://web.archive.org/web/20110709043223/http://cneh09.dal.ca/Schenk_CNEH.pdf The Retirement of Sterling as a Reserve Currency after 1945: Lessons for the US Dollar?]", Catherine R. Schenk, Canadian Network for Economic History conference, October 2009.</ref> In 1944, when the US dollar was chosen as the world reference currency at Bretton Woods, it was only the second currency in global reserves.<ref name=Schenk_2009/>

The [[G8]] also frequently issues public statements as to [[exchange rates]]. In the past due to the [[Plaza Accord]], its predecessor bodies could directly manipulate rates to reverse large [[trade deficit]]s.

===United States dollar===
{{further|International use of the U.S. dollar|Dedollarisation}}

The [[United States dollar]] is the most widely held currency in the allocated reserves. As of the fourth quarter of 2022, the USD accounted for 58.36% of official foreign exchange reserves.<ref>{{cite news|title=Calls to move away from the U.S. dollar are growing — but the greenback is still king|url=https://www.cnbc.com/2023/04/24/economic-and-political-factors-behind-acceleration-of-de-dollarization.html|website=CNBC|date=April 2023 |last1=Chen|first1=Penny}}</ref><ref>{{cite web|title=Currency composition of International Foreign Reserves|url=https://data.imf.org/?sk=E6A5F467-C14B-4AA8-9F6D-5A09EC4E62A4|website=IMF}}</ref>{{update needed|reason=source dated 2022|date=September 2024}} This makes it somewhat easier for the United States to run higher trade deficits with greatly postponed economic ramifications or even postponing a [[currency crisis]]. Central bank US dollar reserves, however, are small compared to private holdings of such debt. If non-United States holders of dollar-denominated assets decided to shift holdings to assets denominated in other currencies, then there could be serious consequences for the US economy. The decline of the pound sterling took place gradually over time, and the markets involved adjusted accordingly.<ref name=Schenk_2009/> However, the US dollar remains the preferred reserve currency in the 2010s because of its stability due to scale and liquidity.<ref>{{cite news|url=https://www.economist.com/business-finance/displaystory.cfm?story_id=16064067&source=hptextfeature |title=In a world of ugly currencies, the dollar is sitting pretty |newspaper=The Economist|date= 6 May 2010|access-date=22 August 2010}}</ref>

The US dollar's position in global reserves is often questioned because of the growing share of unallocated reserves, and because of the doubt regarding dollar stability in the long term.<ref>[http://online.wsj.com/article/SB10001424052748703313304576132170181013248.html Why the Dollar's Reign Is Near an End]</ref><ref>[https://www.reuters.com/article/us-economy-un-idUSTRE74O6EI20110525 "U.N. sees risk of crisis of confidence in dollar"], Reuters, 25 May 2011</ref> However, in the aftermath of the 2008 to 2010 financial crisis, the dollar's share in the world's foreign-exchange trades rose slightly from 85% in 2010 to 87% in 2013.<ref>[http://www.project-syndicate.org/commentary/jeffrey-frankel-argues-that-the-dollar-s-status-as-the-world-s-top-international-currency-is-not-in-jeopardy "The Dollar and Its Rivals"] by Jeffrey Frankel, ''Project Syndicate'', 21 November 2013</ref>{{better source needed|reason=opinion blog|date=May 2023}}{{update inline|date=May 2023}}

In 2025, after the decision by the [[Trump administration]] to impose [[Tariffs in the second Trump administration|tariffs as protectionist trade policy]], financial institutions began to rethink the role of US Dollar as reserve currency.<ref>{{Cite news |last=Partington |first=Richard |date=2025-04-11 |title=The damage is done: Trump's tariffs put the dollar's safe haven status in jeopardy |url=https://www.theguardian.com/business/2025/apr/11/the-damage-is-done-trumps-tariffs-put-the-dollars-global-reserve-status-at-risk |access-date=2025-04-14 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref> For example, Ray Attrill, head of FX strategy at [[National Australia Bank]], said, "The whole premise of the dollar as a reserve currency is being challenged, effectively, by what we've seen since Trump's election."<ref>{{Cite news |last=Wee |first=Rae |date=2025-04-11 |title=Mighty U.S. dollar feels heat as Trump's tariffs spark trade turmoil |url=https://www.reuters.com/markets/currencies/mighty-us-dollar-feels-heat-trumps-tariffs-spark-trade-turmoil-2025-04-11/ |access-date=2025-04-14 |work=Reuters}}</ref> George Saravelos at [[Deutsche Bank]] also said that “the market is re-assessing the structural attractiveness of the dollar as the world’s global reserve currency, and is undergoing a process of rapid de-dollarisation.”<ref>{{Cite news |last=Stepek |first=John |date=2025-04-11 |title=Are the US Dollar's Days of Dominance Numbered? |url=https://www.bloomberg.com/news/newsletters/2025-04-11/trump-tariffs-are-the-us-dollar-s-days-of-dominance-numbered |access-date=2025-04-14 |work=Bloomberg}}</ref>

===Euro===
{{Further|International status and usage of the euro}}
The [[euro]] is currently the second most commonly held reserve currency, representing about 20% of international foreign currency reserves. After World War II and the [[Wirtschaftswunder|rebuilding of the German economy]], the [[Deutsche Mark|German mark]] gained the status of the second most important reserve currency after the US dollar. When the euro was [[Introduction of the euro|introduced]] on 1 January 1999, replacing the mark, [[French franc]] and ten other European currencies, it inherited the status of a major reserve currency from the mark. Since then, its contribution to official reserves has risen continually as banks seek to diversify their reserves, and trade in the [[eurozone]] continues to expand.<ref>{{cite web|url=http://www.imf.org/external/pubs/ft/wp/2006/wp06153.pdf |title=The Euro's Challenge to the Dollar: Different Views from Economists and Evidence from COFER (Currency Composition of Foreign Exchange Reserves) and Other Data |first=Ewe-Ghee |last=Lim |publisher=[[International Monetary Fund|IMF]] |date=June 2006 }}</ref>

After the [[euro]]'s share of global official foreign exchange reserves approached 25% as of year-end 2006 (vs 65% for the [[U.S. dollar]]; see table above), some experts have predicted that the euro could replace the dollar as the world's primary reserve currency. See [[Alan Greenspan]], 2007;<ref>[https://www.reuters.com/article/bondsNews/idUSL1771147920070917 "Euro could replace dollar as top currency-Greenspan"], Reuters, 7 September 2007</ref>
and Frankel, Chinn (2006) who explained how it could happen by 2020.<ref>{{cite journal |last= Menzie |first= Chinn |author2= Jeffery Frankel |date= January 2006 |title= Will the Euro Eventually Surpass The Dollar As Leading International Reserve Currency? |journal= [[NBER]] |url= http://www.wage.wisc.edu/uploads/Working%20Papers/chinnfrankel_NBER_eurotopcurrency.pdf |access-date= 11 October 2007 |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><ref>{{cite web|url=http://mpra.ub.uni-muenchen.de/14350/1/MPRA_paper_14350.pdf |title=Aristovnik, Aleksander & Čeč, Tanja, 2010.

However, as of 2022 none of this has come to fruition due to the [[European debt crisis]] which engulfed the [[PIGS (economics)|PIIGS countries]] from 2009 to 2014. Instead the euro's stability and future existence was put into doubt, and its share of global reserves was cut to 19% by year-end 2015 (vs 66% for the USD). As of year-end 2020 these figures stand at 21% for EUR and 59% for USD.

===Pound sterling===
The United Kingdom's [[pound sterling]] was the primary reserve currency of much of the world in the 19th century and the first half of the 20th century.<ref name=Schenk_2009/> That status ended after the UK almost bankrupted itself fighting [[World War I]]<ref>{{cite news|last=Crafts|first=Nicolas|title=''Walking wounded: The British economy in the aftermath of World War I''|url=https://voxeu.org/article/walking-wounded-british-economy-aftermath-world-war-i|date=27 August 2014|publisher=VoxEU|access-date=13 April 2020}}</ref> and [[World War II]],<ref>{{cite book |last=Chickering |first=Roger |date= January 2013 |title=''A World at Total War'' |url=https://www.cambridge.org/core/books/world-at-total-war/694AD948D65927E2E9787022F31A05D2#fndtn-contents |publisher=Cambridge University Press |isbn=9781139052382 |access-date=12 April 2020}}</ref> and its place was taken by the United States dollar.

===Canadian dollar===
A number of central banks (and commercial banks) keep [[Canadian dollars]] as a reserve currency. In the economy of the Americas, the Canadian dollar plays a similar role to that played by the [[Australian dollar]] (AUD) in the [[Asia-Pacific]] region. The Canadian dollar (as a regional reserve currency for banking) has been an important part of the British, French and Dutch Caribbean states' economies and finance systems since the 1950s.<ref name=bankofcanada>[http://www.bankofcanada.ca/wp-content/uploads/2014/05/boc-review-spring14-pomorski.pdf "The Canadian Dollar as a Reserve Currency"] by Lukasz Pomorski, Francisco Rivadeneyra and Eric Wolfe, Funds Management and Banking Department, [[Bank of Canada|The Bank of Canada]] Review, Spring 2014</ref> The Canadian dollar is also held by many central banks in Central America and South America. It is held in Latin America because of [[remittance]]s and international trade in the region.<ref name=bankofcanada/>

Because Canada's primary foreign-trade relationship is with the United States, Canadian consumers, economists, and many businesses primarily define and value the Canadian dollar in terms of the United States dollar. Thus, by observing how the Canadian dollar floats in terms of the US dollar, foreign-exchange economists can indirectly observe internal behaviours and patterns in the US economy that could not be seen by direct observation. Also, because it is considered a [[petrocurrency|petrodollar]], the Canadian dollar has only fully evolved into a global reserve currency since the 1970s, when it was floated against all other world currencies.

The Canadian dollar, from 2013 to 2017, was ranked fifth among foreign currency reserves in the world, overtaking the Australian dollar, but is then being{{clarify|date=April 2025}} overtaken by the Chinese Yuan.<ref>{{cite web |url=http://www.imf.org/external/np/sta/cofer/eng/ |title=Currency Composition of Official Foreign Exchange Reserves (COFER)|date=30 September 2014 |website=www.imf.org |publisher=International Monetary Fund |access-date=1 October 2014}}</ref>

===Swiss franc===
The [[Swiss franc]], despite gaining ground among the world's foreign-currency reserves<ref>[https://www.cnbc.com/2013/02/14/is-the-dollar-dying-why-us-currency-is-in-danger.html "Is the Dollar Dying?

The daily trading market turnover of the franc, however, ranked fifth, or about 3.4%, among all currencies in a 2007 survey{{needs update|date=April 2025}} by the [[Bank for International Settlements]].<ref name="Triennial-2007">{{cite web

==Calls for an alternative reserve currency==
[[John Maynard Keynes]] proposed the [[bancor]], a supranational currency to be used as unit of account in international trade, as reserve currency under the [[Bretton Woods Conference]] of 1945. The bancor was rejected in favor of the [[U.S. dollar]].

A report released by the [[United Nations Conference on Trade and Development]] in 2010, called for abandoning the U.S. dollar as the single major reserve currency. The report states that the new reserve system should not be based on a single currency or even multiple national currencies but instead permit the emission of international liquidity to create a more stable global financial system.<ref>{{cite news

Countries such as Russia and China, central banks, and economic analysts and groups, such as the [[Gulf Cooperation Council]], have expressed a desire to see an independent new currency replace the dollar as the reserve currency. However, it is recognized that the US dollar remains the strongest reserve currency.<ref>{{Cite web|date=2 June 2020|title=Will the Gulf currency peg survive?|url=https://www.quorumcentre.com/will-the-gulf-currency-peg-survive/|access-date=12 March 2021|website=Quorum Centre for Strategic Studies|language=en-GB|archive-date=19 December 2022|archive-url=https://web.archive.org/web/20221219163324/https://www.quorumcentre.com/will-the-gulf-currency-peg-survive/|url-status=dead}}</ref>

On 10 July 2009, Russian President Medvedev proposed a new '[[World currency]]' at the G8 meeting in London as an alternative reserve currency to replace the dollar.<ref>{{cite news

At the beginning of the 21st century, gold and [[crude oil]] were still priced in dollars, which helps export inflation and has brought complaints about [[OPEC]]'s policies of managing [[Production quota#Crude oil|oil quota]]s to maintain dollar [[price stability]].<ref>Burleigh, Marc.

Due to the [[Russian invasion of Ukraine]] and international sanctions, Russia has used the [[United Arab Emirates dirham]] as a neutral currency when selling oil to India.<ref>{{cite web|url=https://www.reuters.com/business/energy/indian-refiners-pay-traders-dirhams-russian-oil-2023-02-03/|title=Indian refiners pay traders in dirhams for Russian oil|website=[[Reuters]] |archive-url=https://web.archive.org/web/20230203181844/https://www.reuters.com/business/energy/indian-refiners-pay-traders-dirhams-russian-oil-2023-02-03/ |archive-date=3 February 2023 }}</ref><ref>{{cite web|url=https://asia.nikkei.com/Economy/Trade/Indian-imports-of-Russian-oil-drop-to-lowest-in-a-year|title=Indian imports of Russian oil drop to lowest in a year}}</ref>

===Special drawing rights===
Some have proposed the use of the [[International Monetary Fund]]'s (IMF) [[special drawing rights]] (SDRs) as a reserve. The value of SDRs are calculated from a basket determined by the IMF of key international currencies, which as of 2016 consisted of the [[United States dollar]], [[Euro]], [[Japanese yen]], [[Pound sterling]] and [[Renminbi|PRC Renminbi]].

Ahead of a [[G20]] summit in 2009, China distributed a paper that proposed using SDRs for clearing international payments and eventually as a reserve currency to replace the U.S. dollar.<ref>{{cite news|url=https://www.reuters.com/article/wtUSInvestingNews/idUSLJ93633020090319 |title=China backs talks on dollar as reserve -Russian source, Reuters, 19 March 2, 2009 |publisher=Reuters.com |date= 19 March 2009|access-date=22 August 2010}}</ref>

=== Cryptocurrencies ===
According to some cryptocurrency proponents, digital [[cryptocurrency|cryptocurrencies]] could potentially replace fiat currencies as a possible global reserve currency.<ref>{{Cite news |last1=Mattackal |first1=Lisa Pauline |last2=Singh |first2=Medha |date=2022-04-12 |title=Cryptoverse: 10 billion reasons bitcoin could become a reserve currency |language=en |work=Reuters |url=https://www.reuters.com/business/cryptoverse-10-billion-reasons-bitcoin-could-become-reserve-currency-2022-04-12/ |access-date=2023-03-25}}</ref>
