Eurozone
a.k.a. Euro area
The group of EU countries that use the euro as their currency.
In plain English
The group of EU countries that use the euro as their currency.
The eurozone (or euro area) is every EU country that has swapped its own currency for the euro. Its members share one central bank, the ECB, and one interest rate.
Germany, France, Italy and Spain are the biggest economies in it. Membership has grown over time, with Bulgaria the most recent to join in 2026. Some EU countries, such as Sweden, Poland and Denmark, still keep their own currencies.
