Consolidation in banking and financial stability in Europe : empirical evidence

Using aggregate balance sheet data from banks across the EU-25 over the period from 1997 to 2005 this paper provides empirical evidence that national banking market concentration has a negative impact on European banks’ financial soundness as measured by the Z-score technique while controlling for macroeconomic, bank-specific, regulatory, and institutional factors. Furthermore, we find that Eastern European banking markets exhibiting a lower level of competitive pressure, fewer diversification opportunities and a higher fraction of government-owned banks are more prone to financial fragility whereas capital regulations have supported financial stability across the entire European Union. -- Market structure ; Financial stability ; Banking regulation
