Is the euro a good idea?
It matters to anyone living in, trading with or studying the euro area. It is the core question of European economic integration.
Side A
Yes, and worth defending
Lower trading costs, a deeper single market, and political integration.
Evidence
Membership has kept growing: Croatia joined in 2023 and Bulgaria in 2026. Eurobarometer surveys show consistently high public support for the euro in the euro area.
Side B
Flawed by design
One interest rate for very different economies, without a shared budget or high labour mobility.
Evidence
Mundell's optimum currency area theory (1961; Nobel 1999) sets out the conditions. Friedman and Feldstein warned in the 1990s; the 2010–12 crisis hit exactly where they predicted.
