Article 3 of the Treaty on European Union
Article 119 of the Treaty on the Functioning of the European Union
Article 140 of the Treaty on the Functioning of the European Union
This is the process of aligning economic and monetary policies in the Member States and it comprises three stages.
While the first two stages of EMU have been completed for all Member States, the final stage is still ongoing. To date, 21 Member States have adopted the euro as their official currency (collectively referred to as the euro area).
Before it can introduce the euro, a Member State must first meet several economic and legal requirements – the convergence criteria set out in Article 140 TFEU:
When a Member State fulfils all of these requirements, the Council of the European Union decides that it may adopt the euro as its currency. The euro then replaces the national currency and becomes that Member State’s official currency.
Member States in which the currency is the euro are considered to form the euro area, in which a single monetary policy is conducted under the responsibility of the Governing Council of the ECB.
The Member States that have not yet adopted the euro as their currency are Member States with a derogation pursuant to Article 139 TFEU. The European Commission and the ECB report to the Council, at least every two years, or at the request of the Member State with a derogation, on their progress towards fulfilling the convergence criteria. After consulting the European Parliament and after discussion in the European Council, the Council decides on a proposal from the Commission that the Member State concerned fulfils the necessary conditions and may adopt the euro as its currency, and repeals the derogation for the Member State concerned.
The ECB plays a central role in EMU. Through its decision-making body, the Governing Council, it sets the monetary policy for the euro area. It also has the exclusive right to authorise the issue of euro banknotes within the EU. Member States may issue euro coins, but the ECB must first authorise the annual amount (volume) to be issued.
