EU Single Market

Setting the scene

The EU single market formally came into effect on January 1, 1993, completing the project launched by the 1986 Single European Act. It created the 'four freedoms'—free movement of goods, services, capital, and people—across 12 member states. Physical border controls for goods were abolished, and mutual recognition of standards allowed products legal in one country to be sold in others.

What happened

The single market was the core of European integration, creating the world's largest trading bloc with 340 million consumers. It required harmonizing 282 pieces of legislation on everything from food safety to professional qualifications. The project was driven by Jacques Delors, European Commission president, and supported by business seeking economies of scale.

Why it still matters

The 1993 single market transformed Europe's economy, increasing trade and competition, and laying the groundwork for the euro currency in 1999. It made European integration irreversible and demonstrated that economic integration could drive political unity. The single market remains the EU's greatest achievement, though Brexit in 2020 showed that membership was not permanent.

Border checks fell inside the bloc.
