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.

Should I Stay or Should I Go? Bank Productivity and Internationalization Decisions

Claudia M. Buch C. T. Koch Michael Koetter

in: Journal of Banking and Finance, No. 42, 2014

Abstract

Differences in firm-level productivity explain international activities of non-financial firms quite well. We test whether differences in bank productivity determine international activities of banks. Based on a dataset that allows tracking banks across countries and across different modes of foreign entry, we model the ordered probability of maintaining a commercial presence abroad and the volume of banks’ international assets empirically. Our research has three main findings. First, more productive banks are more likely to enter foreign markets in increasingly complex modes. Second, more productive banks also hold larger volumes of foreign assets. Third, higher risk aversion renders entry less likely, but it increases the volume of foreign activities conditional upon entry.

The Impact of Public Guarantees on Bank Risk-taking: Evidence from a Natural Experiment

Reint E. Gropp C. Gruendl Andre Guettler

in: Review of Finance, No. 2, 2014

Abstract

In 2001, government guarantees for savings banks in Germany were removed following a lawsuit. We use this natural experiment to examine the effect of government guarantees on bank risk-taking. The results suggest that banks whose government guarantee was removed reduced credit risk by cutting off the riskiest borrowers from credit. Using a difference-in-differences approach we show that none of these effects are present in a control group of German banks to whom the guarantee was not applicable. Furthermore, savings banks adjusted their liabilities away from risk-sensitive debt instruments after the removal of the guarantee, while we do not observe this for the control group. We also document that yield spreads of savings banks’ bonds increased significantly right after the announcement of the decision to remove guarantees, while the yield spread of a sample of bonds issued by the control group remained unchanged. The evidence implies that public guarantees may be associated with substantial moral hazard effects.

Do Banks Benefit from Internationalization? Revisiting the Market Power–Risk Nexus

Claudia M. Buch C. T. Koch Michael Koetter

in: Review of Finance, No. 4, 2013

Abstract

We analyze the impact of bank internationalization on domestic market power (Lerner index) and risk for German banks. Risk is measured by the official declaration of regulatory authorities that a bank is distressed. We distinguish the volume of foreign assets, the number of foreign countries, and different modes of foreign entry. Our analysis has three main results. First, higher market power is associated with lower risk. Second, holding assets in many countries reduce market power at home, but banks with a higher share of foreign assets exhibit higher market power. Third, bank internationalization is only weakly related to bank risk.

Initial Evidence from a New Database on Capital Market Restrictions

Makram El-Shagi

in: Panoeconomicus, No. 3, 2012

Abstract

One of the key obstacles to the empirical analysis of capital controls has been the unavailability of a detailed set of indicators for controls that cover a broad set of countries over a range of years. In this paper, we propose a new set of indicators derived from the Annual Reports on Exchange Arrangements and Export Restrictions. Contrary to most earlier attempts to construct control indicators from this source, our set of indices allows one to analyze the control intensity separately for inflow, outflow and repatriation controls. An additional set of indicators features information on the institutional design of controls. At first glance, the data show that the financial crisis caused a surge in capital market restrictions, most notably concerning the derivatives market. This reflex, which is not justified by the scarce empirical evidence on the success of controls, shows the importance of having a valid measure to allow an econometrically sound policy evaluation in this field. The data are available from the author upon request.

The Distorting Impact of Capital Controls

Makram El-Shagi

in: German Economic Review, No. 1, 2012

Abstract

This paper uses panel data to show that capital controls have a significant impact on international interest rate differentials. Various types of controls can be distinguished within the data. The analysis shows that the aforementioned effects of capital controls on interest rates are especially strong in the case of capital import controls on portfolio capital; the implementation of these controls has been suggested in the wake of the Asian Crisis to prevent further crises. The results presented herein contradict the hypothesis that capital controls can achieve a restructuring of the maturity of capital inflows without a distortion in international capital allocation.

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.
