Eurozone — Definition Explained Simply | Examples & Role

Eurozone is an association of several European Union countries that have adopted the euro as their official currency.


The Eurozone is a group of European Union member states that have abandoned their national currencies and switched to a single currency — the euro (EUR). Today, most EU countries are part of the Eurozone, and the euro is their official legal tender.

The Eurozone was formed in 1999 when the euro was introduced in non-cash form, and since 2002 euro banknotes and coins have been in circulation. The economic and monetary policy of Eurozone countries is coordinated by the European Central Bank (ECB), which is responsible for the stability of the euro, monetary policy, and inflation control.

Key features of the Eurozone

The Eurozone and EU countries

It is important to understand that EU membership does not automatically mean participation in the Eurozone. Some EU countries have kept their national currencies and do not belong to the monetary union. For example, Poland uses the zloty, Hungary the forint, and Sweden the krona. These countries are EU members but are not part of the Eurozone.

The Eurozone and the global economy

The Eurozone is the second most significant currency zone in the world after the United States. The euro is used in international trade, investment, and is one of the key reserve currencies. Economic processes in the Eurozone directly influence global financial markets.
