Integrated, open and resilient: Europe’s strengths in a fragmenting world

Ireland’s open economy highlights Europe’s integration into global markets, but exposure to external shocks—such as shifts in US trade policy or capital flows—demonstrates the need for resilience. The ECB warns that geopolitical shocks increasingly disrupt growth, inflation and financial stability, citing Russia’s war in Ukraine, Middle East conflicts and tariffs as recent examples. Supply-driven inflation has surged in recent years, while volatile energy prices and cyber threats amplify risks to bond markets, investment funds and bank lending. The financial system has absorbed shocks so far, but the ECB cautions against complacency, noting that resilience requires stronger buffers and diversified funding to withstand abrupt disruptions.

The EU’s heavy reliance on energy imports—57% of total energy, nearly all oil and gas—was exposed when Russia’s invasion of Ukraine triggered the bloc’s largest energy shock since the 1970s. Europe responded by expanding LNG import capacity and reducing dependence on Russian supplies, yet subsequent Middle East tensions showed that resilience depends on more than diversification. The ECB emphasizes that resilience also requires robust capital and liquidity buffers, secure payment systems and the ability to absorb shocks across countries and sectors. Differences in energy mixes and financial structures mean shocks hit Member States unevenly, underscoring the need for European risk-sharing mechanisms.

Fragmentation within the Single Market imposes costs equivalent to high internal tariffs—around 67% for goods and 95% for services—according to ECB estimates, deterring cross-border business and reinforcing a home bias in investment. While frictions in cross-border equity holdings within the euro area have eased since 2014, integration with the US has progressed faster, with estimated tariff-equivalent barriers falling by about 25 percentage points compared to 12 points within the euro area. This trend risks diverting European savings to US markets, leaving EU capital markets underdeveloped and increasing dependence on a single external partner.

The ECB argues that Europe’s strength lies in deeper integration, not retreat, and calls for stronger mechanisms to share risks and diversify supply chains across borders. It highlights venture capital disparities, with US funds investing roughly six times more than EU-based funds, which can push successful start-ups to relocate headquarters or list outside the EU. The central bank stresses that reducing fragmentation—through harmonized rules and streamlined procedures—is essential to unlock Europe’s potential and mitigate the costs of a fragmenting global economy.
