Applied Economics Letters,
No. 7,
2017
Abstract
The global financial crisis has again shown that it is important to understand the emergence and measurement of risks in the banking sector. However, there is no consensus in the literature which risk proxy works best at the level of the individual bank. A commonly used measure in applied work is the Z-score, which might suffer from calculation issues given poor data quality. Motivated by the variety of bank risk proxies, our analysis reveals that nonperforming assets are a well-suited complement to the Z-score in studies of bank risk.

How Do Insured Deposits Affect Bank Risk? Evidence from the 2008 Emergency Economic Stabilization Act
Claudia Lambert, Felix Noth, Ulrich Schüwer
Journal of Financial Intermediation,
January
2017
Abstract
This paper tests whether an increase in insured deposits causes banks to become more risky. We use variation introduced by the U.S. Emergency Economic Stabilization Act in October 2008, which increased the deposit insurance coverage from $100,000 to $250,000 per depositor and bank. For some banks, the amount of insured deposits increased significantly; for others, it was a minor change. Our analysis shows that the more affected banks increase their investments in risky commercial real estate loans and become more risky relative to unaffected banks following the change. This effect is most distinct for affected banks that are low capitalized.

On the Nonexclusivity of Loan Contracts: An Empirical Investigation
Hans Degryse, Vasso Ioannidou, Erik von Schedvin
Management Science,
No. 12,
2016
Abstract
We study how a bank's willingness to lend to a previously exclusive firm changes once the firm obtains a loan from another bank ("outside loan") and breaks an exclusive relationship. Using a difference-in-difference analysis and a setting where outside loans are observable, we document that an outside loan triggers a decrease in the initial bank's willingness to lend to the firm, i.e., outside loans are strategic substitutes. Consistent with concerns about coordination problems and higher indebtedness, we find that this reaction is more pronounced the larger the outside loan and it is muted if the initial bank's existing and future loans retain seniority and are protected with valuable collateral. Our results give a benevolent role to transparency enabling banks to mitigate adverse effects from outside loans. The resulting substitute behavior may also act as a stabilizing force in credit markets limiting positive comovements between lenders, decreasing the possibility of credit freezes and financial crises.

Sovereign Credit Risk Co-movements in the Eurozone: Simple Interdependence or Contagion?
Manuel Buchholz, Lena Tonzer
International Finance,
No. 3,
2016
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.

Bank Response to Higher Capital Requirements: Evidence from a Quasi-natural Experiment
Reint E. Gropp, Thomas Mosk, Steven Ongena, Carlo Wix
Abstract
We study the impact of higher capital requirements on banks’ balance sheets and its transmission to the real economy. The 2011 EBA capital exercise provides an almost ideal quasi-natural experiment, which allows us to identify the effect of higher capital requirements using a difference-in-differences matching estimator. We find that treated banks increase their capital ratios not by raising their levels of equity, but by reducing their credit supply. We also show that this reduction in credit supply results in lower firm-, investment-, and sales growth for firms which obtain a larger share of their bank credit from the treated banks.

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.

European Bank Efficiency and Performance: The Effects of Supranational Versus National Bank Supervision
Rients Galema, Michael Koetter
T. Beck, B. Casu (eds): The Palgrave Handbook of European Banking, London,
2016
Abstract
This chapter explores European bank efficiency and performance. First, the authors provide an overview of the key estimation methods for efficiency and discuss selected applications to the European banking sector. Second, they apply stochastic frontier analysis to investigate the extent to which the reallocation of supervisory powers is associated with efficiency differences between European banks. In doing so, the discussion focuses particularly on whether direct supervision by the Single Supervisory Mechanism (SSM) as opposed to national competent authority (NCA) is related to cost and profit efficiency.

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.

Foreign Funding Shocks and the Lending Channel: Do Foreign Banks Adjust Differently?
Felix Noth, Matias Ossandon Busch
Finance Research Letters,
November
2016
Abstract
We document for a set of Latin American emerging countries that the different nature of foreign funding accessed by foreign and local banks affected their lending performance after September 2008. We show that lending growth was weaker for shock-affected foreign banks compared to shock-affected local banks. This evidence represents valuable policy information for regulators concerned with the stability and well-functioning of banking sectors.

Preisverzerrungen Fehlanzeige – Keine Hinweise für Effekte der Bankenrettung in den USA
Felix Noth, Karolin Vogt
Wirtschaft im Wandel,
No. 4,
2016
Abstract
Im Zuge der Finanzkrise der Jahre 2007 bis 2009 rückte die Kontroverse um staatliche Notrettungsprogramme für den Bankensektor verstärkt ins Blickfeld. Diese Programme haben das Ziel, den Finanzsektor und somit auch realwirtschaftliche Entwicklungen zu stabilisieren. Dem stehen die finanziellen Kosten zu Lasten des Steuerzahlers, erhöhte Risikoübernahmen durch den Staat sowie mögliche verzerrende Wirkungen auf die Marktstruktur gegenüber. Dieser Artikel diskutiert mögliche Preisverzerrungen durch das Troubled Asset Relief Program (TARP) in den USA aus dem Jahr 2008 vor dem Hintergrund eines aktuellen Forschungsbeitrags, der die langfristigen indirekten Effekte des Programms innerhalb der Gruppe der nicht unterstützten Banken untersucht. Hierbei zeigen sich keine Hinweise dafür, dass das Programm zur Bankenrettung zu nachhaltigen Unterschieden im Bankenwettbewerb nach 2010 geführt hat. Die Zinsmargen von Banken mit einer höheren Rettungswahrscheinlichkeit stiegen nur in der direkten Folgezeit von TARP, d. h. im Jahr 2010 an. Ein signifikanter Anstieg des Kredit- und Depotwachstum der Banken für den Zeitraum von 2010 bis 2013 kann nicht verzeichnet werden.
