Abstract
Das Eigenkapital einer Bank dient aus aufsichtsrechtlicher Sicht zwei Zielen: zum einen dem Ausgleich von Verlusten aus laufenden Geschäften oder der Begleichung von Gläubigeransprüchen im Insolvenzfall, zum anderen der Begrenzung von Verlustrisiken aus bestimmten Geschäften. Ein wichtiger Bestandteil des Eigenkapitals ist dabei das Kernkapital. Das Kernkapital ist der Anteil des Eigenkapitals einer Bank, der dem Institut dauerhaft zur Verfügung steht und somit als echter Verlustpuffer dienen kann. Bestandteile sind unter anderem das Stammkapital, Kapitalrücklagen, Gewinnrücklagen oder eigene Aktien der Bank. Aus dem Kernkapital ergibt sich eine wichtige aufsichtsrechtliche Kenngröße: die Kernkapitalquote (Tier 1 Capital Ratio). Diese berechnet sich als das Verhältnis von Kernkapital zur Summe der Risikoaktiva einer Ba

Taxing Banks: An Evaluation of the German Bank Levy
Claudia M. Buch, Björn Hilberg, Lena Tonzer
Abstract
Bank distress can have severe negative consequences for the stability of the financial system, the real economy, and public finances. Regimes for restructuring and restoring banks financed by bank levies and fiscal backstops seek to reduce these costs. Bank levies attempt to internalize systemic risk and increase the costs of leverage. This paper evaluates the effects of the German bank levy implemented in 2011 as part of the German bank restructuring law. Our analysis offers three main insights. First, revenues raised through the bank levy are minimal, because of low tax rates and high thresholds for tax exemptions. Second, the bulk of the payments were contributed by large commercial banks and the head institutes of savings banks and credit unions. Third, the levy had no effect on the volume of loans or interest rates for the average German bank. For the banks affected most by the levy, we find evidence of fewer loans, higher lending rates, and lower deposit rates.

Macroeconomic Factors and Microlevel Bank Behavior
Claudia M. Buch, S. Eickmeier, Esteban Prieto
Journal of Money, Credit and Banking,
Nr. 4,
2014
Abstract
We analyze the link between banks and the macroeconomy using a model that extends a macroeconomic VAR for the U.S. with a set of factors summarizing conditions in about 1,500 commercial banks. We investigate how macroeconomic shocks are transmitted to individual banks and obtain the following main findings. Backward-looking risk of a representative bank declines, and bank lending increases following expansionary shocks. Forward-looking risk increases following an expansionary monetary policy shock. There is, however, substantial heterogeneity in the transmission of macroeconomic shocks, which is due to bank size, capitalization, liquidity, risk, and the exposure to real estate and consumer loans.

Changing Forces of Gravity: How the Crisis Affected International Banking
Claudia M. Buch, Katja Neugebauer, Christoph Schröder
ZEW Discussion Paper, No. 14-006,
2014
Abstract
The global financial crisis has brought to an end a rather unprecedented period of banks’ international expansion. We analyze the effects of the crisis on international banking. Using a detailed dataset on the international assets of all German banks with foreign affiliates for the years 2002-2011, we study bank internationalization before and during the crisis. Our data allow analyzing not only the international assets of the banks’ headquarters but also of their foreign affiliates. We show that banks have lowered their international assets, both along the extensive and the intensive margin. This withdrawal from foreign markets is the result of changing market conditions, of policy interventions, and of a weakly increasing sensitivity of banks to financial frictions.

The Impact of Public Guarantees on Bank Risk-taking: Evidence from a Natural Experiment
Reint E. Gropp, C. Gruendl, Andre Guettler
Review of Finance,
Nr. 2,
2014
Abstract
In 2001, government guarantees for savings banks in Germany were removed following a lawsuit. We use this natural experiment to examine the effect of government guarantees on bank risk-taking. The results suggest that banks whose government guarantee was removed reduced credit risk by cutting off the riskiest borrowers from credit. Using a difference-in-differences approach we show that none of these effects are present in a control group of German banks to whom the guarantee was not applicable. Furthermore, savings banks adjusted their liabilities away from risk-sensitive debt instruments after the removal of the guarantee, while we do not observe this for the control group. We also document that yield spreads of savings banks’ bonds increased significantly right after the announcement of the decision to remove guarantees, while the yield spread of a sample of bonds issued by the control group remained unchanged. The evidence implies that public guarantees may be associated with substantial moral hazard effects.

Do Better Capitalized Banks Lend Less? Long-run Panel Evidence from Germany
Claudia M. Buch, Esteban Prieto
International Finance,
Nr. 1,
2014
Abstract
Higher capital features prominently in proposals for regulatory reform. But how does increased bank capital affect business loans? The real costs of increased bank capital in terms of reduced loans are widely believed to be substantial. But the negative real-sector implications need not be severe. In this paper, we take a long-run perspective by analysing the link between the capitalization of the banking sector and bank loans using panel cointegration models. We study the evolution of the German economy for the past 44 years. Higher bank capital tends to be associated with higher business loan volume, and we find no evidence for a negative effect. This result holds both for pooled regressions as well as for the individual banking groups in Germany.

Banks’ Financial Distress, Lending Supply and Consumption Expenditure
H. Evren Damar, Reint E. Gropp, Adi Mordel
Abstract
We employ a unique identification strategy linking survey data on household consumption expenditure to bank-level data to estimate the effects of bank financial distress on consumer credit and consumption expenditures. We show that households whose banks were more exposed to funding shocks report lower levels of non-mortgage liabilities. This, however, does not result in lower levels of consumption. Households compensate by drawing down liquid assets to smooth consumption in the face of a temporary adverse lending supply shock. The results contrast with recent evidence on the real effects of finance on firms’ investment and employment decisions.

Zur Wirtschaftspolitik: Strukturreformen auch in Deutschland erforderlich!
Oliver Holtemöller, , Tobias Knedlik, Axel Lindner, Götz Zeddies
Konjunktur aktuell,
Nr. 1,
2014
Abstract
Die günstige konjunkturelle Lage in Deutschland scheint der Wirtschaftspolitik den Blick auf die mittel- bis langfristigen Probleme zu verstellen. Im Bereich der Finanzpolitik liegt der Fokus derzeit auf der Ausweitung von Sozialleistungen. Wachstumsfreundliche Maßnahmen stehen hinten an. Zwar plant die neue Koalition zusätzliche investive Ausgaben, die grundsätzlich das Produktionspotenzial erhöhen könnten. Aber die konsumtiven Ausgaben stehen eindeutig im Vordergrund. Das wichtige Thema der Bund-Länder-Finanzbeziehungen wird auf die lange Bank geschoben, obwohl das Auslaufen der aktuellen Regeln Dringlichkeit gebietet und die Anreizprobleme des aktuellen Länderfinanzausgleichs offenkundig sind. Letztere könnten durch eine höhere Steuerautonomie der Bundesländer, etwa durch Zuschlagsrechte bei der Einkommensteuer, abgemildert werden. Im Bereich der Geldpolitik besteht derzeit die Gefahr, dass das mittelfristige Inflationsziel unterschritten wird. Es gibt zwar noch einige geldpolitische Instrumente, die für zusätzliche Liquiditätsbereitstellung genutzt werden könnten. Allerdings ist die Wirkung der Maßnahmen durch Probleme im Bankensektor derzeit gestört. Deshalb hat der im Jahr 2014 anstehende Stresstest eine hohe Bedeutung für die Wiederherstellung des Vertrauens im Bankensektor. Die Bankenunion sollte beherzt vollendet und nicht durch immer weitere Abstriche in ihrer Wirkung gefährdet werden. Die Europäische Kommission untersucht, ob der hohe deutsche Leistungsbilanzüberschuss auf ein gesamtwirtschaftliches Ungleichgewicht hinweist. Gegenwärtig gibt es allerdings kaum Anzeichen dafür, dass die gesamtwirtschaftliche Lage in Deutschland ungleichgewichtig ist. Der Leistungsbilanzüberschuss erklärt sich daraus, dass in einer alternden Gesellschaft wie der deutschen viel gespart wird und auch wegen der in Zukunft zu erwartenden Knappheit des Faktors Arbeit nicht genug rentierliche Investitionsprojekte im Land zu finden sind. Aus dieser Perspektive steht die Wirtschaftspolitik vor zwei Aufgaben: zum einen, die Risiken ungleichgewichtiger wirtschaftlicher Entwicklungen im Ausland für die Zukunft zu senken, um deutsche Anlagen vor Wertverlusten zu schützen. Zum anderen würde eine erfolgreiche Zuwanderungs- und Integrationspolitik über bessere langfristige Wachstumsperspektiven auch die Attraktivität von Investitionen im Inland erhöhen.

In Search for Yield? Survey-based Evidence on Bank Risk Taking

Journal of Economic Dynamics and Control,
Nr. 43,
2014
Abstract
Monetary policy can have an impact on economic and financial stability through the risk taking of banks. Falling interest rates might induce investment into risky activities. This paper provides evidence on the link between monetary policy and bank risk taking. We use a factor-augmented vector autoregressive model (FAVAR) for the US for the period 1997–2008. Besides standard macroeconomic indicators, we include factors summarizing information provided in the Federal Reserve’s Survey of Terms of Business Lending (STBL). These data provide information on banks׳ new loans as well as interest rates for different loan risk categories and different banking groups. We identify a risk-taking channel of monetary policy by distinguishing responses to monetary policy shocks across different types of banks and different loan risk categories. Following an expansionary monetary policy shock, small domestic banks increase their exposure to risk. Large domestic banks do not change their risk exposure. Foreign banks take on more risk only in the mid-2000s, when interest rates were ‘too low for too long’.

Sovereign Credit Risk, Banks' Government Support, and Bank Stock Returns around the World: Discussion of Correa, Lee, Sapriza, and Suarez

Abstract
In the years leading up to the 2008–09 financial crisis, many banks around the world greatly expanded their balance sheets to take advantage of cheap and abundantly available funding. Access to international funding markets, in particular, made it possible for banks to reach a size that in some cases was a large multiple of their home countries’ gross domestic product (GDP). In Iceland, for example, assets of the banking system reached up to 900% of GDP in 2007. Similarly, by the end of 2008, assets in UK and Swiss banks exceeded 500% of their countries’ GDPs, respectively. Banks may also have grown rapidly because they may have wanted to reach too-big-to-fail status in their country, implying even lower funding cost (Penas and Unal 2004).
The depth and severity of the 2008–09 financial crisis and the subsequent debt crisis in Europe, however, have cast doubts on the ability of governments to bail out banks when they experience severe difficulties, in particular, in financially fragile environments and faced with large budget imbalances. This has resulted in as what some observers have dubbed a “doom loop”: the combination of weak public finances and weak banks results in a vicious cycle, in which the funding cost of banks increases, as the ability of governments to bail out banks is called into question, in turn increasing the funding cost of these banks and making the likelihood that the government will actually have to step in even higher, which in turn increases funding cost to the government and so forth.
Against this background, the paper by Correa et al. (2014) explores the link between sovereign rating changes and bank stock returns. They show large negative reactions of stock returns in response to sovereign ratings downgrades for banks that are expected to receive government support in case of failure. They find the strongest effects in developed economies, where the credibility of government bail outs is higher ex ante, while the effects are smaller in developing and emerging economies. In my view, the paper makes a number of important contributions to the extant literature.
