Sweden does not currently use the euro as its currency and has no plans to replace the existing Swedish krona in the near future. Sweden's Treaty of Accession of 1994 made it subject to the Treaty of Maastricht, which obliges states to join the eurozone once they meet the necessary conditions. Sweden maintains that joining the European Exchange Rate Mechanism II, participation in which for at least two years is a requirement for euro adoption, is voluntary, and has chosen to remain outside pending public approval by a referendum, thereby intentionally avoiding the fulfilment of the adoption requirements.

The euro area, commonly called the eurozone (EZ), is a currency union of 20 member states of the European Union (EU) that have adopted the euro (€) as their primary currency and sole legal tender, and have thus fully implemented EMU policies.
