Eurozone: Structure, Membership and Monetary Governance

Context

Inflation in the Eurozone rose to 3.2% in May, mainly due to higher energy and services costs, indicating renewed price pressures across countries that use the euro currency.

About Eurozone

1. The Eurozone (Euro Area) is the monetary union of European Union (EU) member states that have adopted the euro (€) as their common currency and operate under a unified monetary policy.
2. It represents one of the world’s largest monetary unions and forms the core of the European Economic and Monetary Union (EMU).
3. As of January 2026, the Eurozone comprises 21 member states, with Bulgaria being the latest entrant.
4. Some EU countries, including Czech Republic, Denmark, Hungary, Poland, Romania, and Sweden, continue to use their national currencies and remain outside the Eurozone.
5. The European Central Bank (ECB) is responsible for formulating and implementing monetary policy across the Eurozone.
6. The ECB has exclusive authority over key interest-rate decisions and the issuance of euro banknotes and coins.
7. The ECB is governed by the Governing Council, comprising the Executive Board and the governors of the national central banks of Eurozone member states.
8. The European Stability Mechanism (ESM) provides financial assistance to member states facing economic or sovereign debt crises, thereby supporting financial stability within the Eurozone.

Eurozone Membership

1. Countries seeking membership of the Eurozone must satisfy the Maastricht (Convergence) Criteria, established under the Maastricht Treaty, 1992.
2. The criteria require price stability, sound public finances, exchange-rate stability, and sustainable economic convergence.
3. Except Denmark, all EU member states are legally expected to adopt the euro after meeting the convergence criteria.
4. The Maastricht Treaty does not prescribe a fixed timeline for euro adoption, allowing countries to join when they are adequately prepared.
5. The European Commission and the European Central Bank jointly assess whether a candidate country meets the requirements for Eurozone membership.
