Als Reaktion auf die Finanzkrise unterliegt das Finanzsystem zahlreichen neuen regulatorischen Änderungen. Zum einen wurden bestehende mikroprudenzielle Regeln für Eigenkapital und Liquidität verschärft. Zum anderen wurden makroprudenzielle Instrumente eingeführt. Makroprudenzielle Regulierung hat dabei zum Ziel, systemische Risiken im Finanzsystem frühzeitig zu erkennen, zu reduzieren und somit die Finanzmarktstabilität zu erhöhen. Zudem wurde mit der Einführung der Bankenunion die Aufsicht der größten Banken des Euroraums der Europäischen Zentralbank (EZB) übertragen. Diese Studie untersucht, ob das systemische Risiko von Banken unterschiedlich groß ist, wenn eine europäische im Vergleich zu einer nationalen Perspektive eingenommen wird. Im Anschluss wird die Frage geklärt, welche Faktoren systemisches Risiko beeinflussen und ob sich diese Faktoren zwischen der nationalen und europäischen Ebene unterscheiden. Es zeigt sich, dass Banken auf nationaler Ebene im Durchschnitt etwas mehr zum systemischen Risiko beitragen, wobei es große Unterschiede zwischen Banken und Ländern gibt. Zudem haben größere und profitablere Banken sowie Banken, deren Geschäftsmodell durch eine geringere Kreditvergabe geprägt ist, ein höheres systemisches Risiko.

This paper studies the role of political factors for determining the impact of banking sector distress on sovereign bond yield spreads for a sample of 19 emerging market economies in the period 1994–2013. Using interaction models, I find that the adverse impact of banking sector distress on sovereign solvency is less pronounced for countries with a high degree of political stability, a high level of power sharing within the government coalition, a low level of political constraint within the political system, and for countries run by powerful and effective governments. The electoral cycle pronounces the bank risk–sovereign risk transfer.

Staatliche Zahlungsausfälle haben nicht selten politische Ursachen. Während ökonomische Rahmenbedingungen wie etwa Wirtschaftswachstum, Finanzstabilität oder globale Investorenstimmungen die Zahlungsfähigkeit eines Staates beeinflussen, wird die tatsächliche Rückzahlung von Staatsschulden letztendlich von der einheimischen Regierung entschieden. Die Zahlungswilligkeit einer Regierung spielt daher eine entscheidende Rolle für das Risiko eines staatlichen Zahlungsausfalls. In diesem Artikel wird der Einfluss politischer Faktoren auf das staatliche Ausfallrisiko für 27 Schwellen- und Entwicklungsländer im Zeitraum von 1996 bis 2009 untersucht. Die Auswertung von Anleihedaten zeigt, dass Investoren ein höheres Ausfallrisiko fürchten, falls ein Land politisch instabil ist oder von einer Rechts- bzw. Linkspartei regiert wird. Der Einfluss politischer Faktoren auf das staatliche Ausfallrisiko eines Landes sinkt mit dessen Grad an Demokratie und Integration in die Weltwirtschaft.

In Europe, the financial stability mandate generally rests at the national level. But there is an important exception. Since the establishment of the Banking Union in 2014, the European Central Bank (ECB) can impose stricter regulations than the national regulator. The precondition is that the ECB identifies systemic risks which are not adequately addressed by the macroprudential regulator at the national level. In this paper, we ask whether the drivers of systemic risk differ when applying a national versus a European perspective. We use market data for 80 listed euro-area banks to measure each bank’s contribution to systemic risk (SRISK) at the national and the euro-area level. Our research delivers three main findings. First, on average, systemic risk increased during the financial crisis. The difference between systemic risk at the national and the euro-area level is not very large, but there is considerable heterogeneity across countries and banks. Second, an exploration of the drivers of systemic risk shows that a bank’s contribution to systemic risk is positively related to its size and profitability. It decreases in a bank’s share of loans to total assets. Third, the qualitative determinants of systemic risk are similar at the national and euro-area level, whereas the quantitative importance of some determinants differs.

In response to the Global Crisis, governments have implemented restructuring and resolution regimes backed by funds financed by bank levies. Bank levies aim to internalise system risk externalities and to provide funding for bank recovery and resolution. This column explores bank levy design by considering the German and European cases. The discussion points to the importance of structured policy evaluations to determine the effects of levies.

During the recent financial crisis, governments massively intervened in the banking sector by providing liquidity assistance and capital support to banks in distress. This helped stabilize the financial system in the short run. However, public bailouts also bear the risk of longer-term distortions, for example, by affecting bailout expectations of banks. In this chapter, the authors first provide an overview of state aid interventions during the recent crisis episode. The third section then analyzes the effects of state aid on financial stability from a theoretical view. This is followed by the description of results obtained from empirical studies. The link between the provision of state aid and politics is discussed in the section “Institutional Design and Policy Implications”. Finally, in the section “The European Banking Union” the authors describe the elements of the European Banking Union meant to resolve and restructure banks in distress and to lower the need for public intervention. Based on the preceding analysis, conclusions are drawn regarding the new design.

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.

We construct a novel dataset to measure banks’ business and geographical complexity. Using these measures of complexity, we evaluate how they relate to banks’ idiosyncratic and systemic riskiness. The sample covers stock listed banks in the euro area from 2007 to 2014. Our results show that banks have increased their total number of subsidiaries while business and geographical complexity have declined. Bank stability is significantly affected by our complexity measures, whereas the direction of the effect differs across the complexity measures: Banks with a higher degree of geographical complexity and a higher share of foreign subsidiaries seem to be less stable. In contrast, a higher share of non-bank subsidiaries significantly decreases the probability for a state aid request during the recent crisis period. This heterogeneity advises against the use of a single complexity measure when evaluating the implications of bank complexity.
