Avoiding the Fall into the Loop: Isolating the Transmission of Bank-to-Sovereign Distress in the Euro Area and its Drivers
Hannes Böhm, Stefan Eichler
Abstract
We isolate the direct bank-to-sovereign distress channel within the eurozone’s sovereign-bank-loop by exploiting the global, non-eurozone related variation in stock prices. We instrument banking sector stock returns in the eurozone with exposure-weighted stock market returns from non-eurozone countries and take further precautions to remove any eurozone crisis-related variation. We find that the transmission of instrumented bank distress, while economically relevant, is significantly smaller than the corresponding coefficient in the unadjusted OLS framework, confirming concerns on reverse causality and omitted variables in previous studies. Furthermore, we show that the spillover of bank distress is significantly stronger for countries with poorer macroeconomic performances, weaker financial sectors and financial regulation and during times of elevated political uncertainty.

Housing Consumption and Macroprudential Policies in Europe: An Ex Ante Evaluation
Antonios Mavropoulos, Qizhou Xiong
IWH Discussion Papers,
No. 17,
2018
Abstract
In this paper, we use the panel of the first two waves of the Household Finance and Consumption Survey by the European Central Bank to study housing demand of European households and evaluate potential housing market regulations in the post-crisis era. We provide a comprehensive account of the housing decisions of European households between 2010 and 2014, and structurally estimate the housing preference of a simple life-cycle housing choice model. We then evaluate the effect of a tighter LTV/LTI regulation via counter-factual simulations. We find that those regulations limit homeownership and wealth accumulation, reduces housing consumption but may be welfare improving for the young households.

Effectiveness and (In)Efficiencies of Compensation Regulation: Evidence from the EU Banker Bonus Cap
Stefano Colonnello, Michael Koetter, Konstantin Wagner
Abstract
We investigate the (unintended) effects of bank executive compensation regulation. Capping the share of variable compensation spurred average turnover rates driven by CEOs at poorly performing banks. Other than that, banks‘ responses to raise fixed compensation sufficed to retain the vast majority of non-CEO executives and those at well performing banks. We fail to find evidence that banks with executives that are more affected by the bonus cap became less risky. In fact, numerous results indicate an increase of risk, even in its systemic dimension according to selected measures. The return component of bank performance appears to be unaffected by the bonus cap. Risk hikes are consistent with an insurance effect associated with raised the increase in fixed compensation of executives. The ability of the policy to enhance financial stability is therefore doubtful.

What is holding back the banking union?
The European Commission wants to better regulate and monitor the European banking sector. In many EU Member States, however, the necessary directives are being implemented extremely slowly. Surprisingly, the reasons for this do not lie in politics and banking structures, but in the institutional framework conditions and existing regulations in the Member States, as argued by Michael Koetter, Thomas Krause and Lena Tonzer from the Halle Institute for Economic Research (IWH).

Comments on “Consultation BCBS discussion paper on the regulatory treatment of sovereign exposures”
Michael Koetter, Lena Tonzer
Einzelveröffentlichungen,
2018
Abstract
The BCBS discussion paper on the regulatory treatment of sovereign exposures addresses a so far hardly touched topic as concerns capital regulation. While the regulatory framework has been changed substantially over recent years including the establishment of the European Banking Union, risk weights on sovereign exposures have remained mostly unchanged and sovereign exposures of banks benefit from a favourable capital treatment. This applies despite the fact that the recent European sovereign debt crisis has revealed the potential of a doom loop between bank and sovereign risk and demonstrated that sovereign exposures are by no means “risk-free”. The paper is thus an important proposal how to change the risk evaluation of banks’ sovereign exposures.

Delay Determinants of European Banking Union Implementation
Michael Koetter, Thomas Krause, Lena Tonzer
Abstract
To safeguard financial stability and harmonise regulation, the European Commission substantially reformed banking supervision, resolution, and deposit insurance via EU directives. But most countries delay the transposition of these directives. We ask if transposition delays result from strategic considerations of governments conditional on the state of their financial, regulatory, and political systems? Supervisors might try to protect national banking systems and local politicians maybe reluctant to surrender national sovereignty to deal with failed banks. Alternatively, intricate financial regulation might require more implementation time in large and complex financial and political systems. We therefore collect data on the transposition delays of the three Banking Union directives and investigate observed delay variation across member states. Our correlation analyses suggest that existing regulatory and institutional frameworks, rather than banking market structure or political factors, matter for transposition delays.

Nationale Aufsicht versus Europäische Bankenunion: Unterscheidet sich die Beurteilung der Einflussfaktoren systemischen Risikos von Banken?
Thomas Krause, Talina Sondershaus, Lena Tonzer
Wirtschaft im Wandel,
No. 3,
2017
Abstract
Als Reaktion auf die Finanzkrise unterliegt das Finanzsystem zahlreichen neuen regulatorischen Änderungen. Zum einen wurden bestehende mikroprudenzielle Regeln für Eigenkapital und Liquidität verschärft. Zum anderen wurden makroprudenzielle Instrumente eingeführt. Makroprudenzielle Regulierung hat dabei zum Ziel, systemische Risiken im Finanzsystem frühzeitig zu erkennen, zu reduzieren und somit die Finanzmarktstabilität zu erhöhen. Zudem wurde mit der Einführung der Bankenunion die Aufsicht der größten Banken des Euroraums der Europäischen Zentralbank (EZB) übertragen. Diese Studie untersucht, ob das systemische Risiko von Banken unterschiedlich groß ist, wenn eine europäische im Vergleich zu einer nationalen Perspektive eingenommen wird. Im Anschluss wird die Frage geklärt, welche Faktoren systemisches Risiko beeinflussen und ob sich diese Faktoren zwischen der nationalen und europäischen Ebene unterscheiden. Es zeigt sich, dass Banken auf nationaler Ebene im Durchschnitt etwas mehr zum systemischen Risiko beitragen, wobei es große Unterschiede zwischen Banken und Ländern gibt. Zudem haben größere und profitablere Banken sowie Banken, deren Geschäftsmodell durch eine geringere Kreditvergabe geprägt ist, ein höheres systemisches Risiko.

Real Effects of Bank Capital Regulations: Global Evidence
Yota D. Deli, Iftekhar Hasan
Journal of Banking and Finance,
2017
Abstract
We examine the effect of the full set of bank capital regulations (capital stringency) on loan growth, using bank-level data for a maximum of 125 countries over the period 1998–2011. Contrary to standard theoretical considerations, we find that overall capital stringency only has a weak negative effect on loan growth. In fact, this effect is completely offset if banks hold moderately high levels of capital. Interestingly, the components of capital stringency that have the strongest negative effect on loan growth are those related to the prevention of banks to use as capital borrowed funds and assets other than cash or government securities. In contrast, compliance with Basel guidelines in using Basel- and credit-risk weights has a much less potent effect on loan growth.
