Abstract
We investigate credit risk co-movements and contagion in the sovereign debt markets of 17 industrialized countries during the period 2008–2012. We use dynamic conditional correlations of sovereign credit default swap spreads to detect contagion. This approach allows us to separate contagion channels from the determinants of simple interdependence. The results show that, first, sovereign credit risk co-moves considerably, particularly among eurozone countries and during the sovereign debt crisis. Second, contagion varies across time and countries. Third, similarities in economic fundamentals, cross-country linkages in banking and common market sentiment constitute the main channels of contagion.

State Aid and Guarantees in Europe
Reint E. Gropp, Lena Tonzer
T. Beck, B. Casu (eds): The Palgrave Handbook of European Banking, London,
2016
Abstract
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.

Taxing Banks: An Evaluation of the German Bank Levy
Claudia M. Buch, Björn Hilberg, Lena Tonzer
Journal of Banking and Finance,
November
2016
Abstract
Bank distress can have severe negative consequences for the stability of the financial system. Regimes for the restructuring and resolution of banks, financed by bank levies, aim at reducing these costs. This paper evaluates the German bank levy, which has been implemented since 2011. Our analysis offers three main insights. First, revenues raised through the levy were lower than expected. Second, the bulk of the payments were contributed by large commercial banks and by the central institutions of savings banks and credit unions. Third, for those banks, which were affected by the levy, we find evidence for a reduction in lending and higher deposit rates.

International Banking and Cross-border Effects of Regulation: Lessons from Germany
Jana Ohls, Markus Pramor, Lena Tonzer
Abstract
We analyze the inward and outward transmission of regulatory changes through German banks’ (international) loan portfolio. Overall, our results provide evidence for international spillovers of prudential instruments, these spillovers are however quite heterogeneous between types of banks and can only be observed for some instruments. For instance, foreign banks located in Germany reduce their loan growth to the German economy in response to a tightening of sector-specific capital buffers, local reserve requirements and loan to value ratios in their home country. Furthermore, from the point of view of foreign countries, tightening reserve requirements was effective in reducing lending inflows from German banks. Finally, we find that business and financial cycles matter for lending decisions.

Abstract
Das Votum der britischen Bevölkerung, den EU-Verbund verlassen zu wollen, hat zu Turbulenzen auf den Finanzmärkten geführt. Bereits vor dem Referendum am 23. Juni 2016 war ein starker Rückgang der Kurse britischer Bankaktien zu beobachten, wenn die Wahrscheinlichkeit eines Brexits in den Umfragen über 50% stieg, verbunden mit einer Abwertung des britischen Pfunds gegenüber den meisten anderen wichtigen Währungen einschließlich des Euro.

Brexit (Probability) and Effects on Financial Market Stability
Thomas Krause, Felix Noth, Lena Tonzer
IWH Online,
No. 5,
2016
Abstract
On 23 June 2016, there will be a referendum in the United Kingdom (UK) on the stay of the country in the European Union (EU). Based on recent poll data, the share of supporters and opponents of an exit varies around 50%. Opponents of the UK breaking up with Brussels („Brexit“) refer to high costs in terms of stagnating economic growth if the UK leaves the EU. The risk of reduced trade, declining foreign direct investment, and a lower degree of financial market integration is high following an exit of the “single market”.

The Role of Complexity for Bank Risk during the Financial Crisis: Evidence from a Novel Dataset
Thomas Krause, Talina Sondershaus, Lena Tonzer
Abstract
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.

Central Bank Transparency and Cross-border Banking
Stefan Eichler, Helge Littke, Lena Tonzer
Abstract
We analyze the effect of central bank transparency on cross-border bank activities. Based on a panel gravity model for cross-border bank claims for 21 home and 47 destination countries from 1998 to 2010, we find strong empirical evidence that a rise in central bank transparency in the destination country, on average, increases cross-border claims. Using interaction models, we find that the positive effect of central bank transparency on cross-border claims is only significant if the central bank is politically independent. Central bank transparency and credibility are thus considered complements by banks investing abroad.
