euro

Single currency of the European Union (EU), which was officially launched on 1 January 1999 in 11 of the then 15 EU member states (Austria, Belgium, Finland, France, Germany, Republic of Ireland, Italy, Luxembourg, the Netherlands, Portugal, and Spain). Greece adopted the euro on 1 January 2001. Euro notes and coins were introduced from 1 January 2002, circulating in parallel with national currencies for two months. Thereafter the national currencies were abolished.

The launch represented the start of the third and final stage of EU economic and monetary union (EMU). On that date conversion rates between national currencies and the euro were irrevocably fixed. The euro became the legal currency in participating states and the European Central Bank (ECB) took on responsibility for the monetary policy of the eurozone. The UK, Sweden, and Denmark chose not to take part, while Greece was unable to meet the economic convergence criteria at that time. A referendum in Denmark in 2000 rejected adoption of the single currency by 53% to 47%, and a referendum in Sweden in 2003 rejected the euro 56% to 42%. The UK government has set out five economic tests that will have to be met before any decision to join can be made.
