The introduction of the euro was a major step forward in European integration. Around 330 million EU citizens now use it as their currency.
Early stages
When it was launched on 1 January 1999, the euro became the new official currency of 11 Member States, replacing the old national currencies in two stages.
It was first introduced as an accounting currency for non-cash payments and accounting purposes, while the old currencies continued to be used for cash payments.
Euro banknotes and coins were put into circulation for cash payments on 1 January 2002.
Not all EU member states use the euro as their currency. Denmark and the United Kingdom have opt-out clauses exempting them from participation unless and until they choose to participate. All member states must meet specific conditions before adopting the single currency.
Euro adoption
Euro adoption depends upon member states meeting "convergence criteria" designed to ensure that their economies are ready to benefit from joining the euro area.
The Commission and the ECB analyse this convergence in reports. The Eurogroup then examines these reports and makes a recommendation to the Council on decisions relating to euro adoption.
Taking into account the Eurogroup recommendation, the full Council of all EU member states adopts a formal decision on adoption of the euro by member states that fulfil the convergence criteria.
