Bulgaria joins the euro area and advances in monetary integration

Philip R. Lane, Member of the Executive Board of the ECB, delivered a keynote speech at The World Ahead 2026: Sofia Gala Dinner. He congratulated Bulgaria on joining the euro area, noting the smooth euro cash changeover with no disruptions to payment systems. By the end of the dual lev/euro circulation period (31 January 2026), euro banknotes and coins accounted for 70% of total cash in circulation in Bulgaria. Preliminary analysis indicates the changeover had a minor impact on the price level, similar to other countries adopting the euro.

While Bulgaria’s lev tracked the euro for years, it had no role in monetary policy decisions. Now, Bulgaria has a seat at the ECB policymaking table, with Governor Radev contributing to the Governing Council and Bulgarian National Bank staff participating in Eurosystem committees.

Mr. Lane outlined common policy challenges for euro area countries, including geopolitical shifts, digitalisation, demography, environmental sustainability, and international financial system changes. He emphasized that a monetary union provides a coordinated response to external risks and structural changes, offering benefits such as increased transaction insulation, deeper financial markets, and more efficient infrastructure.

He highlighted reforms that have strengthened Europe’s financial resilience, including banking supervision, macroprudential measures, the European Stability Mechanism, and ECB liquidity tools. These reforms support the stability and effectiveness of the monetary union.

Regarding Bulgaria, Mr. Lane noted the importance of high-quality national policies. Structural reforms to improve institutions, governance, and the business environment are crucial. Bulgaria’s ongoing convergence will likely lead to faster growth, higher inflation, and credit expansion, requiring close monitoring and precautionary measures, such as macroprudential policies implemented by the Bulgarian National Bank.

He recommended increasing capital expenditure, improving public investment management, combating the informal economy, and reforming state-owned enterprises and the pension system to ensure fiscal sustainability.

In conclusion, 2026 marks a milestone for Bulgaria and the euro area. Bulgaria’s active role enhances its sovereignty, and both the euro area and Bulgaria benefit from increased scale and integration, provided domestic policies and institutions are strengthened.
