Launch of the euro

Conditions at the time

Lengthy integration preparations and testing of computer and settlement systems preceded the launch.

How events unfolded

The new currency launched on 1/1, followed by market trading and the first refinancing operation.

Stakeholders and impacts

The ECB, national central banks and financial institutions carried out the transition.

Information available at the time

An ECB speech in late month 1 explained the initial technical transition and market operations.

Findings confirmed later

A smooth initial launch was not sufficient grounds to judge long-term institutional performance immediately.

Alternative interpretations and limitations

The currency’s launch is not equated with cash replacement, and economic conditions were not identical across participating countries.

Source-based context and interpretation

The ECB's early speech separated a smooth operational start from a judgment on long-term performance. Physical notes and coins were introduced later after separate preparations; dual circulation preceded the euro becoming the sole legal tender. Monetary-policy launch and everyday cash replacement were different stages. ASSETCASTING interpretation: One currency-union date can obscure the difference between financial-market operations and everyday payments. A successful operational changeover does not establish completed economic convergence or political integration.
