Bank Risk Proxies and the Crisis of 2007/09: A Comparison

Applied Economics Letters,
Nr. 7,

Abstract
The global financial crisis has again shown that it is important to understand the emergence and measurement of risks in the banking sector. However, there is no consensus in the literature which risk proxy works best at the level of the individual bank. A commonly used measure in applied work is the Z-score, which might suffer from calculation issues given poor data quality. Motivated by the variety of bank risk proxies, our analysis reveals that nonperforming assets are a well-suited complement to the Z-score in studies of bank risk.

Sovereign Credit Risk Co-movements in the Eurozone: Simple Interdependence or Contagion?
Manuel Buchholz, Lena Tonzer
International Finance,
Nr. 3,
2016
Abstract
We investigate credit risk co-movements and contagion in the sovereign debt markets of 17 industrialized countries during the period 2008–2012. We use dynamic conditional correlations of sovereign credit default swap spreads to detect contagion. This approach allows us to separate contagion channels from the determinants of simple interdependence. The results show that, first, sovereign credit risk co-moves considerably, particularly among eurozone countries and during the sovereign debt crisis. Second, contagion varies across time and countries. Third, similarities in economic fundamentals, cross-country linkages in banking and common market sentiment constitute the main channels of contagion.

State Aid and Guarantees in Europe
Reint E. Gropp, Lena Tonzer
T. Beck, B. Casu (eds): The Palgrave Handbook of European Banking, London,
2016
Abstract
During the recent financial crisis, governments massively intervened in the banking sector by providing liquidity assistance and capital support to banks in distress. This helped stabilize the financial system in the short run. However, public bailouts also bear the risk of longer-term distortions, for example, by affecting bailout expectations of banks. In this chapter, the authors first provide an overview of state aid interventions during the recent crisis episode. The third section then analyzes the effects of state aid on financial stability from a theoretical view. This is followed by the description of results obtained from empirical studies. The link between the provision of state aid and politics is discussed in the section “Institutional Design and Policy Implications”. Finally, in the section “The European Banking Union” the authors describe the elements of the European Banking Union meant to resolve and restructure banks in distress and to lower the need for public intervention. Based on the preceding analysis, conclusions are drawn regarding the new design.

Lend Global, Fund Local? Price and Funding Cost Margins in Multinational Banking
Rients Galema, Michael Koetter, C. Liesegang
Review of Finance,
Nr. 5,
2016
Abstract
In a proposed model of a multinational bank, interest margins determine local lending by foreign affiliates and the internal funding by parent banks. We exploit detailed parent-affiliate-level data of all German banks to empirically test our theoretical predictions in pre-crisis times. Local lending by affiliates depends negatively on price margins, the difference between lending and deposit rates in foreign markets. The effect of funding cost margins, the gap between local deposit rates faced by affiliates abroad and the funding costs of their parents, on internal capital market funding is positive but statistically weak. Interest margins are central to explain the interaction between internal capital markets and foreign affiliates lending.

Structural Reforms in Banking: The Role of Trading
Jan Pieter Krahnen, Felix Noth, Ulrich Schüwer
Abstract
In the wake of the recent financial crisis, significant regulatory actions have been taken aimed at limiting risks emanating from trading in bank business models. Prominent reform proposals are the Volcker Rule in the U.S., the Vickers Report in the UK, and, based on the Liikanen proposal, the Barnier proposal in the EU. A major element of these reforms is to separate “classical” commercial banking activities from securities trading activities, notably from proprietary trading. While the reforms are at different stages of implementation, there is a strong ongoing discussion on what possible economic consequences are to be expected. The goal of this paper is to look at the alternative approaches of these reform proposals and to assess their likely consequences for bank business models, risk-taking and financial stability. Our conclusions can be summarized as follows: First, the focus on a prohibition of only proprietary trading, as envisaged in the current EU proposal, is inadequate. It does not necessarily reduce risk-taking and it likely crowds out desired trading activities, thereby negatively affecting financial stability. Second, there is potentially a better solution to limit excessive trading risk at banks in terms of potential welfare consequences: Trading separation into legally distinct or ring-fenced entities within the existing banking organizations. This kind of separation limits cross-subsidies between banking and proprietary trading and diminishes contagion risk, while still allowing for synergies across banking, non-proprietary trading and proprietary trading.

To Separate or not to Separate Investment from Commercial Banking? An Empirical Analysis of Attention Distortion under Multiple Tasks
Reint E. Gropp, K. Park
IWH Discussion Papers,
Nr. 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.

International Banking and Liquidity Risk Transmission: Evidence from Canada
James Chapman, H. Evren Damar
IMF Economic Review,
Nr. 3,
2015
Abstract
This paper investigates how liquidity conditions in Canada may affect domestic and/or foreign lending of globally active Canadian banks, and whether this transmission is influenced by individual bank characteristics. It finds that Canadian banks expanded their foreign lending during the recent financial crisis, often through acquisitions of foreign banks. It also finds evidence that internal capital markets play a role in the lending activities of globally active Canadian banks during times of heightened liquidity risk.

Bank Market Power, Factor Reallocation, and Aggregate Growth
R. Inklaar, Michael Koetter, Felix Noth
Journal of Financial Stability,
2015
Abstract
Using a unique firm-level sample of approximately 700,000 firm-year observations of German small and medium-sized enterprises (SMEs), this study seeks to identify the effect of bank market power on aggregate growth components. We test for a pre-crisis sample whether bank market power spurs or hinders the reallocation of resources across informationally opaque firms. Identification relies on the dependence on external finance in each industry and the regional demarcation of regional banking markets in Germany. The results show that bank markups spur aggregate SME growth, primarily through technical change and the reallocation of resources. Banks seem to need sufficient markups to generate the necessary private information to allocate financial funds efficiently.
