The euro is managed and administered by the [[European Central Bank]] and the [[Eurosystem]], composed of the [[central bank]]s of the eurozone countries. As an independent central bank, the ECB has sole authority to set [[monetary policy]]. The Eurosystem participates in the printing, minting and distribution of [[euro banknotes]] and [[euro coins|coins]] in all member states, and the operation of the eurozone payment systems.

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>
