Regulation of International Financial Markets and International Banking

This research group 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).

Aggregate Dynamics with Sectoral Price Stickiness Heterogeneity and Aggregate Real Shocks

Alessandro Flamini Iftekhar Hasan

in: Journal of Money, Credit and Banking, forthcoming

Abstract

<p>This paper investigates the relationship between heterogeneity in sectoral price stickiness and the response of the economy to aggregate real shocks. We show that sectoral heterogeneity reduces inflation persistence for a constant average duration of price spells, and that inflation persistence can fall despite duration increases associated with increases in heterogeneity. We also find that sectoral heterogeneity reduces the persistence and volatility of interest rate and output gap for a constant price spells duration, while the qualitative impact on inflation volatility tends to be positive. A relevant policy implication is that neglecting price stickiness heterogeneity can impair the economic dynamics assessment.</p>

Does It Pay to Get Connected? An Examination of Bank Alliance Network and Bond Spread

Iftekhar Hasan Céline Meslier Amine Tarazi Mingming Zhou

in: Journal of Economics and Business, forthcoming

Abstract

This paper examines the effects of bank alliance network on bonds issued by European banks during the period 1990–2009. We construct six measures capturing different dimensions of banks’ network characteristics. In opposition to the results obtained for non-financial firms, our findings indicate that being part of a network does not create value for bank’s bondholders, indicating a dark side effect of strategic alliances in the banking sector. While being part of a network is perceived as a risk-increasing event by market participants, this negative perception is significantly lower for the larger banks, and, to a lesser extent, for the more profitable banks. Moreover, during crisis times, the positive impact on bond spread of a bank’s higher centrality or of a bank’s higher connectedness in the network is stronger, indicating that market participants may fear spillover effects within the network during periods of banks’ heightened financial fragility.

The Effect of Bank Organizational Risk-management on the Price of Non-deposit Debt

Iftekhar Hasan Emma Peng Maya Waisman Meng Yan

in: Journal of Financial Services Research, April 2024

Abstract

<p>We test whether organizational risk management matters to bondholders of U.S. bank holding companies (BHCs), and find that debt financing costs increase when the BHC has lower-quality risk management. Consistent with bailouts giving rise to moral hazard among bank creditors, we find that bondholders put less emphasis on risk management in large institutions for which bailouts are expected ex-ante. BHCs that maintained strong risk management before the financial crisis had lower debt costs during and after the crisis, compared to other banks. Overall, quality risk management can curtail risk exposures at BHCs and result in lower debt costs.</p>

Ownership Structure and the Cost of Debt: Evidence From the Chinese Corporate Bond Market

Sris Chatterjee Xian Gu Iftekhar Hasan Haitian Lu

in: Journal of Empirical Finance, September 2023

Abstract

Drawing upon evidence from the Chinese corporate bond market, we study how ownership structure affects the cost of debt for firms. Our results show that state, institutional and foreign ownership formats reduce the cost of debt for firms. The benefits of state ownership are accentuated when the issuer is headquartered in a province with highly developed market institutions, operates in an industry less dominated by the state or during the period after the 2012 anti-corruption reforms. Institutional ownership provides the most benefits in environments with lower levels of marketization, especially for firms with low credit quality. Our evidence sheds light on the nexus of ownership and debt cost in a political economy where state-owned enterprises (SOEs) and non-SOEs face productivity and credit frictions. It is also illustrative of how the market environment interacts with corporate ownership in affecting the cost of bond issuance.

Cultural Values of Parent Bank Board Members and Lending by Foreign Subsidiaries: The Moderating Role of Personal Traits

Iftekhar Hasan Krzysztof Jackowicz Oskar Kowalewski Łukasz Kozłowski

in: Journal of International Financial Markets, Institutions and Money, March 2023

Abstract

In this study, we investigate whether the cultural values of a parent bank’s board members affect lending by the bank’s foreign subsidiaries and how this influence is moderated by the board members’ personal traits. Using a new dataset on foreign-owned banks and their parent companies, we find that average individualism, uncertainty avoidance, and indulgence within parent bank boards significantly impact lending by foreign subsidiaries. We establish that different sensitivities of female and male directors modify the relevance of individual cultural dimensions in lending by foreign bank subsidiaries. Moreover, we show that parent bank directors’ cultural values have a stronger impact on lending by the bank’s foreign subsidiaries when those directors have enough time to fulfill their duties and possess higher ownership stakes in the parent companies.

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.

Inside Asset Purchase Programs: The Effects of Unconventional Policy on Banking Competition

Michael Koetter Natalia Podlich Michael Wedow

in: ECB Working Paper Series, No. 2017, 2017

Abstract

We test if unconventional monetary policy instruments influence the competitive conduct of banks. Between q2:2010 and q1:2012, the ECB absorbed Euro 218 billion worth of government securities from five EMU countries under the Securities Markets Programme (SMP). Using detailed security holdings data at the bank level, we show that banks exposed to this unexpected (loose) policy shock mildly gained local loan and deposit market shares. Shifts in market shares are driven by banks that increased SMP security holdings during the lifetime of the program and that hold the largest relative SMP portfolio shares. Holding other securities from periphery countries that were not part of the SMP amplifies the positive market share responses. Monopolistic rents approximated by Lerner indices are lower for SMP banks, suggesting a role of the SMP to re-distribute market power differentially, but not necessarily banking profits.

Uncertainty, Financial Crises, and Subjective Well-being

Lena Tonzer

in: IWH Discussion Papers, No. 2, 2017

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 20 countries over the period from 2000 to 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, 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.

To Separate or not to Separate Investment from Commercial Banking? An Empirical Analysis of Attention Distortion under Multiple Tasks

Reint E. Gropp K. Park

in: IWH Discussion Papers, No. 2, 2016

Abstract

In the wake of the 2008/2009 financial crisis, a number of policy reports (Vickers, Liikanen, Volcker) proposed to separate investment banking from commercial banking to increase financial stability. This paper empirically examines one theoretical justification for these proposals, namely attention distortion under multiple tasks as in Holmstrom and Milgrom (1991). Universal banks can be viewed as combining two different tasks (investment banking and commercial banking) in the same organization. We estimate pay-performance sensitivities for different segments within universal banks and for pure investment and commercial banks. We show that the pay-performance sensitivity is higher in investment banking than in commercial banking, no matter whether it is organized as part of a universal bank or in a separate institution. Next, the paper shows that relative pay-performance sensitivities of investment and commercial banking are negatively related to the quality of the loan portfolio in universal banks. Depending on the specification, we obtain a reduction in problem loans when investment banking is removed from commercial banks of up to 12 percent. We interpret the evidence to imply that the higher pay-performance sensitivity in investment banking directs the attention of managers away from commercial banking within universal banks, consistent with Holmstrom and Milgrom (1991). Separation of investment banking and commercial banking may indeed be associated with a reduction in risk in commercial banking.
