Regulierung internationaler Finanzmärkte und Banken

Die Forschungsgruppe "Regulierung internationaler Finanzmärkte und Banken" analysiert internationale Kapitalströme und die Auswirkungen von Regulierungsänderungen auf die Finanzstabilität. Integrierte Finanzmärkte begünstigen eine effiziente Kapitalallokation und Risikoteilung – sie erleichtern aber auch die grenzüberschreitende Übertragung von Schocks.

Dementsprechend hat sich die Bankenregulierung in den letzten Jahren weiterentwickelt, wobei die vollen Auswirkungen dieser Reformen noch unklar sind. Daher konzentriert sich die Forschung der Gruppe auf zwei Bereiche:

Erstens werden die Haupttreiber internationaler Kapitalströme und deren Auswirkungen auf Finanzstabilität untersucht. Zeiten hoher Finanzintegration sind oft gefolgt von Krisen mit nachhaltigen realwirtschaftlichen Folgen. Ziel ist es, zu verstehen, wie eine stabile und effektive Kreditvergabe gewährleistet werden kann.

Zweitens wird untersucht, wie sich Veränderungen in der Regulierung und Aufsicht auf das grenzüberschreitende Bankgeschäft auswirken, insbesondere im Kontext der europäischen Integration. Dazu gehört die Bewertung des Trade-offs zwischen regulatorischer Harmonisierung und unbeabsichtigten Marktverzerrungen.

Zwei Datenprojekte tragen zu diesen Forschungsthemen bei: die International Banking Library, eine webbasierte Plattform für den Forschungsaustausch mit einem vierteljährlichen Newsletter, der mehr als 700 Abonnenten erreicht, und die Financial Markets Directives Database, die die Umsetzung der wichtigsten EU-Vorschriften im Bereich Finanzmärkte mit besonderem Schwerpunkt auf der Europäischen Bankenunion dokumentiert. Gemeinsam fördern sie eine evidenzbasierte Politikanalyse und erhöhen die Sichtbarkeit der Gruppe.

Interactions Between Bank Levies and Corporate Taxes: How is Bank Leverage Affected?

Franziska Bremus Kirsten Schmidt Lena Tonzer

in: Journal of Banking and Finance, Nr. 105874, September 2020

Abstract

Regulatory bank levies set incentives for banks to reduce leverage. At the same time, corporate income taxation makes funding through debt more attractive. In this paper, we explore how regulatory levies affect bank capital structure, depending on corporate income taxation. Based on bank balance sheet data from 2006 to 2014 for a panel of EU-banks, our analysis yields three main results: The introduction of bank levies leads to lower leverage as liabilities become more expensive. This effect is weaker the more elevated corporate income taxes are. In countries charging very high corporate income taxes, the incentives of bank levies to reduce leverage turn insignificant. Thus, bank levies can counteract the debt bias of taxation only partially.

Financial Incentives and Loan Officer Behavior: Multitasking and Allocation of Effort under an Incomplete Contract

Patrick Behr Alejandro H. Drexler Reint E. Gropp Andre Guettler

in: Journal of Financial and Quantitative Analysis, Nr. 4, 2020

Abstract

We investigate the implications of providing loan officers with a nonlinear compensation structure that rewards loan volume and penalizes poor performance. Using a unique data set provided by a large international commercial bank, we examine the main activities that loan officers perform: loan prospecting, screening, and monitoring. We find that when loan officers are at risk of losing their bonuses, they increase prospecting and monitoring. We further show that loan officers adjust their behavior more toward the end of the month when bonus payments are approaching. These effects are more pronounced for loan officers with longer tenures at the bank.

Banks’ Equity Performance and the Term Structure of Interest Rates

Elyas Elyasiani Iftekhar Hasan Elena Kalotychou Panos K. Pouliasis Sotiris Staikouras

in: Financial Markets, Institutions and Instruments, Nr. 2, 2020

Abstract

Using an extensive global sample, this paper investigates the impact of the term structure of interest rates on bank equity returns. Decomposing the yield curve to its three constituents (level, slope and curvature), the paper evaluates the time-varying sensitivity of the bank’s equity returns to these constituents by using a diagonal dynamic conditional correlation multivariate GARCH framework. Evidence reveals that the empirical proxies for the three factors explain the variations in equity returns above and beyond the market-wide effect. More specifically, shocks to the long-term (level) and short-term (slope) factors have a statistically significant impact on equity returns, while those on the medium-term (curvature) factor are less clear-cut. Bank size plays an important role in the sense that exposures are higher for SIFIs and large banks compared to medium and small banks. Moreover, banks exhibit greater sensitivities to all risk factors during the crisis and postcrisis periods compared to the pre-crisis period; though these sensitivities do not differ for market-oriented and bank-oriented financial systems.

The Dilemma of International Diversification: Evidence from the European Sovereign Debt Crisis

Bill Francis Iftekhar Hasan Gergana L. Kostova Sami Ben Naceur

in: Asia-Pacific Journal of Financial Studies, Nr. 2, 2020

Abstract

This paper tests how capital markets value the international diversification of banks in good and in bad economic times by investigating changes in domestic and foreign sovereign debt ratings before and during the European sovereign debt crisis. Tracing 320 European banks in 29 countries and 226 credit rating announcements for European sovereigns between 1 January 2001 and 15 August 2012, we show that the market values banks with access to foreign funds. Despite occasional adverse effects immediately following negative news regarding sovereign credit rating changes, international diversification was found to be beneficial to European banks, especially during periods of distress.

Cross-border Transmission of Emergency Liquidity

Thomas Kick Michael Koetter Manuela Storz

in: Journal of Banking and Finance, April 2020

Abstract

We show that emergency liquidity provision by the Federal Reserve transmitted to non-U.S. banking markets. Based on manually collected holding company structures, we identify banks in Germany with access to U.S. facilities. Using detailed interest rate data reported to the German central bank, we compare lending and borrowing rates of banks with and without such access. U.S. liquidity shocks cause a significant decrease in the short-term funding costs of the average German bank with access. This reduction is mitigated for banks with more vulnerable balance sheets prior to the inception of emergency liquidity. We also find a significant pass-through in terms of lower corporate credit rates charged for banks with the lowest pre-crisis leverage, US-dollar funding needs, and liquidity buffers. Spillover effects from U.S. emergency liquidity provision are generally confined to short-term rates.

Banks’ foreign homes

Kirsten Schmidt Lena Tonzer

in: Deutsche Bundesbank Discussion Papers, Nr. 46, 2024

Abstract

<p>Our results reveal that higher lending spreads between foreign and home markets redirect real estate backed lending towards foreign markets offering a higher interest rate, which provides evidence for "search for yield" behavior. This re-allocation is found especially for banks with more expertise on the foreign market due to a higher local activity and holds for commercial and residential real estate backed loans. Furthermore, "search for yield" behavior and a resulting increase in foreign real estate backed lending is found when macroprudential regulation is missing or misaligned between a bank’s country of residence and the destination country. When turning to the question of whether the detected search for yield behavior results in more risk, we find that especially better capitalized banks report higher forbearance ratios as they might face less stigma effects compared to low capitalized banks.</p>

The Effect of Firm Subsidies on Credit Markets

Aleksandr Kazakov Michael Koetter Mirko Titze Lena Tonzer

in: IWH Discussion Papers, Nr. 24, 2022

Abstract

<p>We use project-level information for the largest regional economic development program in German history to study how government subsidies to firms affect credit markets. We identify credit market responses by considering both, bank lending and firm borrowing during 1998-2019. We find that subsidies lead to larger lending volumes without crowding out credit to non-subsidized firms. Banks that are more exposed to subsidized firms exhibit moderately higher credit risk though. Firm subsidies support lending especially when credit constraints are elevated during the years of the financial crisis.</p>

Climate Change-Related Regulatory Risks and Bank Lending

Isabella Müller Eleonora Sfrappini

in: ECB Working Paper, Nr. 2670, 2022

Abstract

We identify the effect of climate change-related regulatory risks on credit real-location. Our evidence suggests that effects depend borrower's region. Following an increase in salience of regulatory risks, banks reallocate credit to US firms that could be negatively impacted by regulatory interventions. Conversely, in Europe, banks lend more to firms that could benefit from environmental regulation. The effect is moderated by banks' own loan portfolio composition. Banks with a portfolio tilted towards firms that could be negatively a affected by environmental policies increasingly support these firms. Overall, our results indicate that financial implications of regulation associated with climate change appear to be the main drivers of banks' behavior.

Explaining Regional Disparities in Housing Prices Across German Districts

Lars Brausewetter Stephan L. Thomsen Johannes Trunzer

in: IWH Discussion Papers, Nr. 13, 2022

Abstract

Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: Growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: Increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.

Stress-ridden Finance and Growth Losses: Does Financial Development Break the Link?

Serafín Martínez-Jaramillo Ricardo Montañez-Enríquez Matias Ossandon Busch Manuel Ramos-Francia Anahí Rodríguez-Martínez José Manuel Sánchez-Martínez

in: IWH Discussion Papers, Nr. 3, 2022

Abstract

Does financial development shield countries from the pass-through of financial shocks to real outcomes? We evaluate this question by characterising the probability density of expected GDP growth conditional on financial stability indicators in a panel of 28 countries. Our robust results unveil a non-linear nexus between financial stability and expected GDP growth, depending on countries’ degree of financial development. While both domestic and global financial factors affect expected growth, the effect of global factors is moderated by financial development. This result highlights a previously unexplored channel trough which financial development can break the link between financial (in)stability and GDP growth.
