Regulation of International Financial Markets and International Banking

This research group analyses causes and consequences of banks' international activities and the regulatory framework they operate in.

Internationally active banks can facilitate an efficient international allocation of capital and provide channels for international risk sharing. But they can also be a source of financial instabilities themselves, thus contributing to international contagion and risk-shifting. This is one reason for the current re-regulation of international banking.

The research group contributes to the literature in three ways. First, the group empirically analyses the channels through which shocks are transmitted by internationally active banks. Second, the group analyses the build-up of aggregate imbalances in integrated banking markets and resulting consequences for the real economy. Third, the group analyses the impact of changes in banking supervision and regulation on (inter)national activities of banks, with a special focus on the European integration process.

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.

Foreign Bank Ownership and Income Inequality: Empirical Evidence

Manthos D. Delis Iftekhar Hasan Nikolaos Mylonidis

in: Applied Economics, No. 11, 2020

Abstract

Using country-level panel data over 1995–2013 on within-country income inequality and foreign bank presence, this paper establishes a positive relation between the two, running from higher foreign bank presence to income inequality. Given that foreign bank participation increased by 62% over the period 1995 to 2013, our baseline results imply a 5.8% increase in the Gini coefficient on average over this period, ceteris paribus. These results are robust to the inclusion of country and year fixed effects and to the use of restrictions on foreign bank entry in the host countries as an instrumental variable. We show that this positive effect is channelled through the lack of greenfield entry and the associated lower levels of competition.

Comparing Financial Transparency between For-profit and Nonprofit Suppliers of Public Goods: Evidence from Microfinance

John W. Goodell Abhinav Goyal Iftekhar Hasan

in: Journal of International Financial Markets, Institutions and Money, January 2020

Abstract

Previous research finds market financing is favored over relationship financing in environments of better governance, since the transaction costs to investors of vetting asymmetric information are thereby reduced. For industries supplying public goods, for-profits rely on market financing, while nonprofits rely on relationships with donors. This suggests that for-profits will be more inclined than nonprofits to improve financial transparency. We examine the impact of for-profit versus nonprofit status on the financial transparency of firms engaged with supplying public goods. There are relatively few industries that have large number of both for-profit and nonprofit firms across countries. However, the microfinance industry provides the opportunity of a large number of both for-profit and nonprofit firms in relatively equal numbers, across a wide array of countries. Consistent with our prediction, we find that financial transparency is positively associated with a for-profit status. Results will be of broad interest both to scholars interested in the roles of transparency and transaction costs on market versus relational financing; as well as to policy makers interested in the impact of for-profit on the supply of public goods, and on the microfinance industry in particular.

Foreign Ownership, Bank Information Environments, and the International Mobility of Corporate Governance

Yiwei Fang Iftekhar Hasan Woon Sau Leung Qingwei Wang

in: Journal of International Business Studies, No. 9, 2019

Abstract

This paper investigates how foreign ownership shapes bank information environments. Using a sample of listed banks from 60 countries over 1997–2012, we show that foreign ownership is significantly associated with greater (lower) informativeness (synchronicity) in bank stock prices. We also find that stock returns of foreign-owned banks reflect more information about future earnings. In addition, the positive association between price informativeness and foreign ownership is stronger for foreign-owned banks in countries with stronger governance, stronger banking supervision, and lower monitoring costs. Overall, our evidence suggests that foreign ownership reduces bank opacity by exporting governance, yielding important implications for regulators and governments.

Delay Determinants of European Banking Union Implementation

Michael Koetter Thomas Krause Lena Tonzer

in: European Journal of Political Economy, 2019

Abstract

Most countries in the European Union (EU) delay the transposition of European Commission (EC) directives, which aim at reforming banking supervision, resolution, and deposit insurance. We compile a systematic overview of these delays to investigate if they result from strategic considerations of governments conditional on the state of their financial, regulatory, and political systems. Transposition delays pertaining to the three Banking Union directives differ considerably across the 28 EU members. Bivariate regression analyses suggest that existing national bank regulation and supervision drive delays the most. Political factors are less relevant. These results are qualitatively insensitive to alternative estimation methods and lag structures. Multivariate analyses highlight that well-stocked deposit insurance schemes speed-up the implementation of capital requirements, banking systems with many banks are slower in implementing new bank rescue and resolution rules, and countries with a more intensive sovereign-bank nexus delay the harmonization of EU deposit insurance more.

Firm Subsidies, Financial Intermediation, and Bank Stability

Aleksandr Kazakov Michael Koetter Mirko Titze Lena Tonzer

in: IWH Discussion Papers, No. 24, 2022

Abstract

We use granular project-level information for the largest regional economic development program in German history to study whether government subsidies to firms affect the quantity and quality of bank lending. We combine the universe of recipient firms under the Improvement of Regional Economic Structures program (GRW) with their local banks during 1998-2019. The modalities of GRW subsidies to firms are determined at the EU level. Therefore, we use it to identify bank outcomes. Banks with relationships to more subsidized firms exhibit higher lending volumes without any significant differences in bank stability. Subsidized firms, in turn, borrow more indicating that banks facilitate regional economic development policies.

Climate Change-Related Regulatory Risks and Bank Lending

Isabella Müller Eleonora Sfrappini

in: ECB Working Paper, No. 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, No. 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, No. 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.

Do We Want These Two to Tango? On Zombie Firms and Stressed Banks in Europe

Manuela Storz Michael Koetter Ralph Setzer Andreas Westphal

in: ECB Working Paper, 2017

Abstract

We show that the speed and type of corporate deleveraging depends on the interaction between corporate and financial sector health. Based on granular bank-firm data pertaining to small and medium-sized enterprises (SME) from five stressed and two non-stressed euro area economies, we show that “zombie” firms generally continued to lever up during the 2010–2014 period. Whereas relationships with stressed banks reduce SME leverage on average, we also show that zombie firms that are tied to weak banks in euro area periphery countries increase their indebtedness even further. Sustainable economic recovery therefore requires both: deleveraging of banks and firms.
