which eu countries don't use the euro
Eurozone The eurozone consists of Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. Other EU states (except for Denmark and the United Kingdom) are obliged to join once they meet the criteria to do so.[8] No state has left, and there are no provisions to do so or to be expelled.[9] Andorra, Monaco, San Marino, and Vatican City have formal agreements with the EU to use the euro as their official currency and issue their own coins.[10][11][12] Kosovo and Montenegro have adopted the euro unilaterally,[13] but these countries do not officially form part of the eurozone and do not have representation in the European Central Bank (ECB) or in the Eurogroup.[14]
History of the euro The euro came into existence on 1 January 1999, although it had been a goal of the European Union (EU) and its predecessors since the 1960s. After tough negotiations, particularly due to opposition from the United Kingdom, the Maastricht Treaty entered into force in 1993 with the goal of creating an economic and monetary union by 1999 for all EU states except the UK and Denmark (even though Denmark has a fixed exchange rate policy with the euro).
