On 7 February 1992, representatives of twelve European Community countries signed the Treaty on European Union at the Gouvernement aan de Maas, the Limburg provincial government complex beside the Meuse in Maastricht. The signatures transformed monetary union from a sequence of political promises into treaty law with institutions, stages, and admission conditions.
The treaty laid the legal foundation for a single currency and for the European Central Bank and European System of Central Banks. It assigned price stability a central role and protected monetary decision-making from instructions by national governments or other political bodies.
Monetary union was divided into stages rather than launched immediately. Capital movements were liberalized first, national central banks and economic policies were brought into closer alignment during the second stage, and a single monetary policy with irrevocably fixed conversion rates would begin only after participating countries passed the required assessments.
Those assessments became known as the Maastricht convergence criteria. They measured inflation and long-term interest rates against the best-performing members, required exchange-rate stability, and set reference values of 3 percent of gross domestic product for annual government deficits and 60 percent for public debt.
The figures were meant to limit the risk that one member's fiscal or inflationary policy would destabilize a currency shared with others. They also became durable political benchmarks, criticized for their rigidity and uneven enforcement but repeatedly invoked in debates over budgets, enlargement, sovereign debt, and access to the euro area.
The treaty entered into force on 1 November 1993; the euro began as an accounting and electronic currency on 1 January 1999, and notes and coins entered circulation in 2002. The building on the Meuse therefore marks a financial constitution rather than a cash launch: it is where governments bound the future currency to rules about central-bank independence, economic convergence, and collective admission.
