The global financial crisis of 2007-08 and its adverse effects on economic activity have put financial stability back on the agenda of both researchers and policymakers. The regulatory debate has since then revolved around the question which reforms are needed to effectively reduce the likelihood and costs of future systemic financial crises. By now, the debate has led to an update of regulatory frameworks on the national, European, and global level. This thesis contributes to the empirical research on the risks to financial stability and to the debate on the regulation of international financial markets. It builds on some of the key insights from the recent global financial crisis and the respective policy responses. Chapter 1 of the thesis analyzes the reasons behind the strong co-movements of credit risk in sovereign bond markets during the financial crisis and the subsequent euro area debt crisis. In addition, it investigates to what extent high co-movements might be the outcome of contagion and through which channels contagion occurs. Chapter 2 investigates how uncertainty in banking affects banks’ loan supply, and it analyzes if the lending behavior is heterogeneous across different types of banks. Turning to the analysis of actual policies, Chapter 3 studies the effect of liquidity provided by the Eurosystem on macroeconomic adjustment in European crisis countries. Finally, Chapter 4 of the thesis assesses the effectiveness of a macroprudential policy instrument, caps on banks’ leverage, in stabilizing credit growth during financial downturns.
