1998 Euro Launch & 1999 Introduction

The launch of the euro was the most ambitious monetary integration project in history. Eleven founding members, Germany, France, Italy, Spain, Netherlands, Belgium, Austria, Portugal, Finland, Ireland, Luxembourg, surrendered national monetary policy to the European Central Bank in Frankfurt. Greece joined in 2001, bringing the original eurozone to 12 before physical euro introduction on January 1, 2002. The political economy was transformative. Germany gave up the deutschmark, the anchor currency of European monetary discipline for four decades. France accepted that a German-dominated ECB would set policy. Italy and Spain gained borrowing costs aligned with German bunds. Peripheral Europe got an immediate bond market convergence rally, Italian 10Y yields fell from 12% in 1995 to 4% by 2000, roughly equal to Germany. The honeymoon lasted a decade. Capital flowed from core Europe to periphery, financing property bubbles in Ireland and Spain and current account deficits in Greece and Portugal. Cross-border banking exposure grew to $10+ trillion. The illusion that euro membership eliminated sovereign risk encouraged leverage that would prove fatal when the 2010 European Debt Crisis exposed the gap between monetary union and fiscal union. The durable lessons concern optimal currency area theory. For a currency union to work without persistent imbalances, members need either (a) similar business cycles (Germany and Greece do not share this), (b) labor mobility (Europe has less than the US), (c) fiscal transfers between regions (the EU budget is 1% of GDP, insufficient), or (d) wage-price flexibility (highly limited in most eurozone economies). The euro had none of these fully, meaning that imbalances must resolve through painful internal devaluation (wages falling) rather than external devaluation (currency falling). The 2010-2015 crisis and its incomplete resolution through OMT, banking union, and eventually the NextGenerationEU recovery fund, all traced back to design choices made in 1999.
