European Single Market The European Single Market, Internal Market or Common Market is a single market which seeks to guarantee the free movement of goods, capital, services, and labour – the "four freedoms" – within the European Union (EU).[1][2][3][4] The market encompasses the EU's 28 member states, and has been extended, with exceptions, to Iceland, Liechtenstein and Norway through the Agreement on the European Economic Area and to Switzerland through bilateral treaties.
List of currencies in Europe A currency is a medium of exchange, such as money, banknotes, and coins.[2] In Europe, the most commonly used currency is the euro; any country entering the European Union (EU) is expected to join the eurozone[3] when they meet the five convergence criteria.[4] Denmark is the only EU member which has been granted an exemption from using the euro,[3] Sweden has also not adopted the Euro, although unlike Denmark, it has not formally opted out, instead, fails to meet the ERM II (Exchange Rate Mechanism) which results in the non-use of the Euro.[5][6] For countries which hope to join the eurozone, there are five guidelines that need to be followed, grouped in the Maastricht criteria.[3]
