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).

The Geography of Information: Evidence from the Public Debt Market

Bill Francis Iftekhar Hasan Maya Waisman

in: Journal of Economic Geography, No. 1, 2023

Abstract

nWe investigate the link between the spatial concentration of firms in large, central metropolitans (i.e. urban agglomeration) and the cost of public corporate debt. Looking at bond issues over the period 1985–2014, we find that bonds issued by companies headquartered in urban agglomerates have lower at-issue yield spreads than bonds issued by firms based in remote, sparsely populated areas. Measures of the count of institutional bondholders in a firm’s vicinity confirm that the spatial cross-sectional variation in bond spreads is driven by the proximity of metropolitan firms to large concentrations of institutional investors. Our results are robust to controls for firm productivity and governance, analyst following, and exogenous shocks to institutional investor attention. The effect of headquarters location on bond spreads is especially pronounced for more difficult to value, speculative-grade bonds, bonds issued by smaller, less visible firms and bonds issued without protective covenants. Overall, we provide evidence that the geographical distribution of firms and investors generates a corresponding distribution of value-relevant, firm-level information that affects its cost of capital.

Financial Linkages and Sectoral Business Cycle Synchronization: Evidence from Europe

Hannes Böhm Julia Schaumburg Lena Tonzer

in: IMF Economic Review, December 2022

Abstract

We analyze whether financial integration leads to converging or diverging business cycles using a dynamic spatial model. Our model allows for contemporaneous spillovers of shocks to GDP growth between countries that are financially integrated and delivers a scalar measure of the spillover intensity at each point in time. For a financial network of ten European countries from 1996 to 2017, we find that the spillover effects are positive on average and much larger during periods of financial stress, pointing towards stronger business cycle synchronization. Dismantling GDP growth into value added growth of ten major industries, we observe that spillover intensities vary significantly. The findings are robust to a variety of alternative model specifications.

Completing the European Banking Union: Capital Cost Consequences for Credit Providers and Corporate Borrowers

Michael Koetter Thomas Krause Eleonora Sfrappini Lena Tonzer

in: European Economic Review, September 2022

Abstract

The bank recovery and resolution directive (BRRD) regulates the bail-in hierarchy to resolve distressed banks in the European Union (EU). Using the staggered BRRD implementation across 15 member states, we identify banks’ capital cost responses and subsequent pass-through to borrowers towards surprise elements due to national transposition details. Average bank capital costs increase heterogeneously across countries with strongest funding cost hikes observed for banks located in GIIPS and non-EMU countries. Only banks in core E(M)U countries that exhibit higher funding costs increase credit spreads for corporate borrowers and contract credit supply. Tighter credit conditions are only passed on to more levered and less profitable firms. On balance, the national implementation of BRRD appears to have strengthened financial system resilience without a pervasive hike in borrowing costs.

A Note of Caution on Quantifying Banks' Recapitalization Effects

Felix Noth Kirsten Schmidt Lena Tonzer

in: Journal of Money, Credit and Banking, No. 4, 2022

Abstract

Unconventional monetary policy measures like asset purchase programs aim to reduce certain securities' yield and alter financial institutions' investment behavior. These measures increase the institutions' market value of securities and add to their equity positions. We show that the extent of this recapitalization effect crucially depends on the securities' accounting and valuation methods, country-level regulation, and maturity structure. We argue that future research needs to consider these factors when quantifying banks' recapitalization effects and consequent changes in banks' lending decisions to the real sector.

Technical Optimum of Bank Liquidity Creation

Iftekhar Hasan Jean-Loup Soula

in: Revue Economique, No. 3, 2022

Abstract

This paper generates a technical optimum of bank liquidity creation benchmark by tracing an efficient frontier in liquidity creation (bank intermediation) and questions why some banks are more efficient than others in such activities. Evidence reveals that medium size banks are most correlated to efficient frontier. Small (large) banks—focused on traditional banking activities—are found to be the most (least) efficient in creating liquidity in on-balance sheet items whereas large banks—involved in non-traditional activities—are found to be most efficient in off-balance sheet liquidity creation. Additionally, the liquidity efficiency of small banks is more resilient during the 2007-2008 financial crisis relative to other banks.

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.
