Regulation of International Financial Markets and International Banking

The research group ‘Regulation of International Financial Markets and International Banking’ analyses international capital flows as well as the consequences of regulatory changes for financial stability and intermediation. Both aspects can facilitate an efficient allocation of capital and enable risk sharing, but spark at the same time global financial instabilities. Banking regulation and supervision has accordingly changed significantly over recent years, but the impact of these comprehensive reforms on the functionality of the financial system remain unclear. In addition banks face further challenges, such as tightening monetary policy, geopolitical risks, and the emergence of new competitors due to digitalization. 

Against this backdrop, the research group contributes to the literature in three ways. First, the group empirically analyses international capital flow determinants and the implications for financial stability and credit allocation. Periods characterised by a high degree of financial integration are often followed by financial crises, causing negative spill-overs to the real economy. This work package seeks to advance our understanding of how to maintain a stable banking system that is able to efficiently channel financial resources to firms and households alike. 

Second, the group analyses the impact of changes in banking supervision and regulation on (inter)national activities of banks with a specific focus on the European integration process. The establishment of the European Banking Union constantly shapes the banking sector as prudential and regulatory responsibilities are transferred from the national to the Euro area level. Integrated markets allow for an early detection of soaring risks at an early stage, but new regulations can also create distortions. This work package contributes to the scant empirical evidence on this trade-off. 

Third, “traditional” banks are not only operating in a tighter regulatory framework, they also face plenty of challenges threatening their business model and longer-term profitability. For example, increasing interest rates sparked deposit withdrawals and valuation losses of banks’ fixed income investment. Distortions due to the realization of political risks and rising levels of public, private, and corporate debt might bear the risk of future non-performing loans. The emergence of non-bank financial intermediaries (FinTech) challenge current business models of banks. The consequences for banks or their new competitors should be monitored.

IWH Data Project: International Banking Library

The International Banking Library is a web-based platform for the exchange of research on cross-border banking. It provides access to data sources, academic research, both theoretical and empirical, on cross-border banking, as well as information on regulatory initiatives. The International Banking Library addresses researchers, policymakers, and students of international banking and economics in search of comprehensive information on international banking issues. 

The contents of the International Banking Library are summarised and distributed in a quarterly newsletter, thereby adding to the international visibility of the IWH (with more than 700 subscribers from academia, central banks and the industry) and facilitating a regular exchange of our research ideas with policy makers.

IWH Data Project: Financial Markets Directives Database

In Europe, financial markets have undergone significant regulatory changes since the last financial and sovereign debt crisis. One key element is the harmonisation of rules for capital regulation, bank resolution and deposit insurance. In the euro area, the sizable change in the regulatory framework is also reflected by the establishment of the European Banking Union. 

Another change that might have implications for financial structure is the establishment of a Capital Market Union. Evidence-based policymaking and the evaluation of (un-)intended consequences of such reforms needs information on when regulatory changes happen. In the European Union, the cornerstones of regulatory changes that apply to all member states are implemented by means of regulations or directives. The latter ones have to be implemented, with some scope for discretion, into national law by the member states. The Financial Markets Directives Database assembles the dates at which countries have published the key legal document related to several recent directives affecting financial markets. 

The cornerstone of the database constitutes information on the European Banking Union including its three directives on capital requirements, bank resolution and deposit insurance (CRD IV, BRRD, DGSD). The database has been made publically available via the website “International Banking Library” and is part of the Centre for Evidence-based Policy Advice (IWH-CEP).

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.

National Culture and Risk-taking: Evidence from the Insurance Industry

Chrysovalantis Gaganis Iftekhar Hasan Panagiota Papadimitri Menelaos Tasiou

in: Journal of Business Research, April 2019

Abstract

The gravity of insurance within the financial sector is constantly increasing. Reasonably, after the events of the recent financial turmoil, the domain of research that examines the factors driving the risk-taking of this industry has been signified. The purpose of the present study is to investigate the interplay between national culture and risk of insurance firms. We quantify the cultural overtones, measuring national culture considering the dimensions outlined by the Hofstede model and risk-taking using the ‘Z-score’. In a sample consisting of 801 life and non-life insurance firms operating across 42 countries over the period 2007–2016, we find a strong and significant relationship among insurance firms' risk-taking and cultural characteristics, such as individualism, uncertainty avoidance and power distance. Results remain robust to a variety of firm and country-specific controls, alternative measures of risk, sample specifications and tests designed to alleviate endogeneity.

Elevated Uncertainty during the Financial Crisis: Do Effects on Subjective Well-being Differ across European Countries?

Lena Tonzer

in: B.E. Journal of Economic Analysis and Policy, No. 2, 2019

Abstract

This paper focuses on the effect of uncertainty as reflected by financial market variables on subjective well-being. The analysis is based on Eurobarometer surveys, covering 18 countries over the period 2000–2013. Individuals report lower levels of life satisfaction in times of higher uncertainty approximated by stock market volatility. This effect is heterogeneous across respondents: the probability of being unsatisfied is higher for respondents who are older, unemployed, less educated, and live in one of the GIIPS countries of the Euro area. Furthermore, higher uncertainty in combination with a financial crisis increases the probability of reporting low values of life satisfaction.

Drivers of Systemic Risk: Do National and European Perspectives Differ?

Claudia M. Buch Thomas Krause Lena Tonzer

in: Journal of International Money and Finance, March 2019

Abstract

With the establishment of the Banking Union, the European Central Bank has been granted the power to impose stricter regulations than the national regulator if systemic risks are not adequately addressed at the national level. We ask whether there is a cross-border externality in the sense that a bank’s systemic risk differs when applying a national versus a European perspective. On average, banks’ contribution to systemic risk is similar at the two regional levels, and so is the ranking of banks. Generally, larger banks and banks with a lower share of loans are more systemically important. The effects of these variables are qualitatively but not quantitatively similar at the national versus the European level.

Banks’ foreign homes

Kirsten Schmidt Lena Tonzer

in: Deutsche Bundesbank Discussion Papers, No. 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>

How Do EU Banks’ Funding Costs Respond to the CRD IV? An Assessment Based on the Banking Union Directives Database

Thomas Krause Eleonora Sfrappini Lena Tonzer Cristina Zgherea

in: IWH Discussion Papers, No. 12, 2024

Abstract

The establishment of the European Banking Union constitutes a major change in the regulatory framework of the banking system. Main parts are implemented via directives that show staggered transposition timing across EU member states. Based on the newly compiled Banking Union Directives Database, we assess how banks’ funding costs responded to the Capital Requirements Directive IV (CRD IV). Our findings show an upward trend in funding costs which is driven by an increase in cost of equity and partially offset by a decline in cost of debt. The diverging trends are most present in countries with an ex-ante lower regulatory capital stringency, which is in line with banks’ short-run adjustment needs but longer-run benefits from increased financial stability.

The Effect of Firm Subsidies on Credit Markets

Aleksandr Kazakov Michael Koetter Mirko Titze Lena Tonzer

in: IWH Discussion Papers, No. 24, 2022

Abstract

<p>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.</p>

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.
