Real Estate Prices and Bank Stability

Journal of Banking and Finance,
No. 34,

Abstract
Real estate prices can deviate from their fundamental value due to rigid supply, heterogeneity in quality, and various market imperfections, which have two contrasting effects on bank stability. Higher prices increase the value of collateral and net wealth of borrowers and thus reduce the likelihood of credit defaults. In contrast, persistent deviations from fundamentals may foster the adverse selection of increasingly risky creditors by banks seeking to expand their loan portfolios, which increases bank distress probabilities. We test these hypotheses using unique data on real estate markets and banks in Germany. House price deviations contribute to bank instability, but nominal house price developments do not. This finding corroborates the importance of deviations from the fundamental value of real estate, rather than just price levels or changes alone, when assessing bank stability.

Shocks at Large Banks and Banking Sector Distress: The Banking Granular Residual
S. Blank, Claudia M. Buch, Katja Neugebauer
Journal of Financial Stability,
No. 4,
2009
Abstract
Size matters in banking. In this paper, we explore whether shocks originating at large banks affect the probability of distress of smaller banks and thus the stability of the banking system. Our analysis proceeds in two steps. In a first step, we follow Gabaix and construct a measure of idiosyncratic shocks at large banks, the so-called Banking Granular Residual. This measure documents the importance of size effects for the German banking system. In a second step, we incorporate this measure of idiosyncratic shocks at large banks into an integrated stress-testing model for the German banking system following De Graeve et al. (2008). We find that positive shocks at large banks reduce the probability of distress of small banks.

Lending Technology, Bank Organization and Competition
Hans Degryse, Steven Ongena, Günseli Tümer-Alkan
Journal of Financial Transformation,
2009
Abstract
This paper reviews recent theoretical and empirical studies investigating how both bank technology and organization shape bank-borrower interactions. We refer to two related concepts for bank technology. First, the technologies banks employ in loan granting decisions and second, the advances in information technology linked to the bank's lending technology. We also summarize and interpret the theoretical and empirical work on bank organization and its influence on lending technologies. We show that the choice of lending technology and bank organization depend heavily on the availability of information, the technological progress in the collection of information, as well as the banking market structure and the legal environment. We draw important policy conclusions from the literature. Competition authorities and supervisors have to remain alert to the consequences of the introduction of any new technology because: (1) advances in technology do not necessarily lead to more intense banking competition, and (2) the impact of technological and financial innovation on financial efficiency and stability depends on the incentives of the entire „loan production chain.‟

Stages of the 2007/2008 Global Financial Crisis: Is there a Wandering Asset Price Bubble?
Lucjan T. Orlowski
Economics E-Journal 43. Munich Personal RePEc Archive 2008,
2009
Abstract
This study identifies five distinctive stages of the current global financial crisis: the meltdown of the subprime mortgage market; spillovers into broader credit market; the liquidity crisis epitomized by the fallout of Northern Rock, Bear Stearns and Lehman Brothers with counterparty risk effects on other financial institutions; the commodity price bubble, and the ultimate demise of investment banking in the U.S. The study argues that the severity of the crisis is influenced strongly by changeable allocations of global savings coupled with excessive credit creation, which lead to over-pricing of varied types of assets. The study calls such process a “wandering asset-price bubble“. Unstable allocations elevate market, credit, and liquidity risks. Monetary policy responses aimed at stabilizing financial markets are proposed.

Banking Integration, Bank Stability, and Regulation: Introduction to a Special Issue of the International Journal of Central Banking
Reint E. Gropp, H. Shin
International Journal of Central Banking,
No. 1,
2009
Abstract
The link between banking integration and financial stability has taken center stage in the wake of the current financial crisis. To what extent is the banking system in Europe integrated? What role has the introduction of the common currency played in this context? Are integrated banking markets more vulnerable to contagion and financial instability? Does the fragmented regulatory framework in Europe pose special problems in resolving bank failures? What policy reforms may become necessary? These questions are of considerable policy interest as evidenced by the extensive discussions surrounding the design and implementation of a new regulatory regime and by the increasing attention coming from academia.

Monetary Policy and Financial (In)stability: An Integrated Micro–Macro Approach
Ferre De Graeve, Thomas Kick, Michael Koetter
Journal of Financial Stability,
No. 3,
2008
Abstract
Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.

International Financial Integration and Stability: On the Causes of the International Banking Crisis 2007/08 and Some Preliminary Lessons.
Diemo Dietrich, Achim Hauck
Wirtschaft im Wandel,
No. 5,
2008
Abstract
Die gemeinhin als „Subprime-Krise“ bezeichneten Turbulenzen auf den internationalen Finanzmärkten beherrschen, seitdem sich im vergangenen Sommer ihre ersten Symptome aufzeigten, weltweit die wirtschaftspolitische Diskussion. Dabei stand zunächst die Frage im Vordergrund, ob und welche Maßnahmen kurzfristig erforderlich sind, um das internationale Finanzsystem zu stabilisieren und mögliche negative realwirtschaftliche Auswirkungen der Krise zu begrenzen. In jüngerer Zeit wird darüber hinausgehend verstärkt diskutiert, welche grundsätzlichen Lehren aus den Ereignissen gezogen werden können und welche Konsequenzen sich für die zukünftige Ausgestaltung nationaler und internationaler Rahmenbedingungen für die internationale Finanzintegration ergeben. In der bisherigen Diskussion wurde eine Vielzahl unterschiedlicher Einzelfaktoren als ursächlich für die Krise betrachtet und mehr oder weniger isoliert voneinander hinsichtlich ihrer möglichen wirtschaftspolitischen Implikationen untersucht. Die Frage nach der Existenz einer gemeinsamen Quelle für diese vielen mutmaßlichen Gründe ist mithin bislang noch nicht in hinreichendem Maß beantwortet, sodass aus der Krise noch keine über Teilaspekte hinausgehende grundsätzlichen Erkenntnisse für die Wirtschaftspolitik abgeleitet werden konnten.
Der vorliegende Beitrag befasst sich zum einen mit der Frage nach der Hauptursache der Krise. Es wird aufgezeigt, dass sie zu einem bedeutenden Teil auf die Integration vormals peripherer und institutionell schwach entwickelter Volkswirtschaften in die Weltwirtschaft und die damit verbundenen globalen Ungleichgewichte zurückgeführt werden kann. Entsprechend ist die Krise nicht nur in ihrer Wirkung, sondern vor allem in ihrer Ursache ein globales und kein vorrangig US-amerikanisches Phänomen. Auf der Grundlage dieses Befunds werden vorläufige Lehren aus der Subprime-Krise für eine stabilitätsorientierte Wirtschaftspolitik in einer integrierten Weltwirtschaft gezogen.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
No. 2,
2008
Abstract
We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a structural model based on utility maximization. Using the almost ideal demand system, we estimate input- and profit-demand functions to obtain proxies for expected return and risk. Efficiency is then measured in this risk-return space. Mean risk-return efficiency is somewhat higher than cost and considerably higher than profit efficiency (PE). More importantly, rank–order correlation between these measures are low or even negative. This suggests that best-practice institutes should not be identified on the basis of traditional efficiency measures alone. Apparently, low cost and/or PE may merely result from alternative yet efficiently chosen risk-return trade-offs.

The Effect of the Iraq War on Foreign Bank Lending to the MENA Region
H. Evren Damar
Emerging Markets Finance and Trade,
No. 5,
2007
Abstract
This paper examines whether a large geopolitical event, such as the war in Iraq, can affect foreign bank lending from developed countries to emerging markets. Using country-level data, the paper analyzes the effects of economic shocks and the Iraq war on the availability of foreign bank credit to five countries in the Middle East and North Africa. The war has had a nonuniform effect on foreign banks: Although the war has led to higher U.S. lending, it has also discouraged British and Italian banks from lending to the region. Implications concerning the stability and reliability of foreign bank credit in the face of increased geopolitical risks are identified and discussed.

Bank Market Discipline
Reint E. Gropp, M. Schleicher
ECB Monthly Bulletin,
2005
Abstract
This article reviews the conceptual issues surrounding market discipline for banks and describes to what extent market discipline could complement supervisory activities. The potential of market discipline has been explicitly recognised in the New Basel Accord. In addition to capital requirements (Pillar I) and supervisory review (Pillar II), the Accord provides for a greater role of financial markets in complementing traditional supervisory activities by asking banks for increased transparency with regard to their operations (Pillar III). This article puts Pillar III in the broader context of direct and indirect market discipline. It is argued that both direct and indirect market discipline should be enhanced by the transparency requirements of the New Capital Accord, but that other conditions may also need to be met in order for market discipline to become more effective. Nevertheless, the article also shows that aggregated market prices can play a useful role in monitoring banking sector stability.
