Real and Financial Innovation

This research group contributes to the scientific literature in three main ways. First, it provides new ways to identify shocks to the financial sector in financial systems and analyses how these shocks affect intermediaries with regard to risk taking (stability), efficiency (productivity) and the market structure in banking markets in general. Second, the identified external shocks are central to measure effects that financial intermediaries have on the real sector of financial systems. Because financial intermediaries play a special role in financial systems and are subject to many regulations, it is very important to understand how, e.g., risk taking incentives or different competition structures in banking markets affect real sector outcome like sales, GDP growth or employment. Third, the group focuses on the effects of foreign banks in financial systems and specifically how shocks to these banks (e.g., via their holding companies during the recent financial crisis) affect activities (e.g., lending) in the host countries.

Relationship Lenders and Unorthodox Monetary Policy: Investment, Employment, and Resource Reallocation Effects

Leibniz Association

We combine a number of unique and proprietary data sources to measure the impact of relationship lenders and unconventional monetary policy during and after the European sovereign debt crisis on the real economy. Establishing systematic links between different research data centers (Forschungsdatenzentren, FDZ) and central banks with detailed micro-level information on both financial and real activity is the stand-alone proposition of our proposal. The main objective is to permit the identification of causal effects, or their absence, regarding which policies were conducive to mitigate financial shocks and stimulate real economic activities, such as employment, investment, or the closure of plants.

Structural Reforms in Banking: The Role of Trading

Jan Pieter Krahnen Felix Noth Ulrich Schüwer

in: Journal of Financial Regulation, No. 1, 2017

Abstract

In the wake of the recent financial crisis, significant regulatory actions have been taken aimed at limiting risks emanating from banks’ trading activities. The goal of this article is to look at the alternative reforms in the US, the UK and the EU, specifically with respect to the role of proprietary trading. Our conclusions can be summarized as follows: First, the focus on a prohibition of proprietary trading, as reflected in the Volcker Rule in the US and in the current proposal of the European Commission (Barnier proposal), is inadequate. It does not necessarily reduce risk-taking and it is likely to crowd out desired trading activities, thereby possibly affecting financial stability negatively. Second, trading separation into legally distinct or ring-fenced entities within the existing banking organizations, as suggested under the Vickers proposal for the UK and the Liikanen proposal for the EU, is a more effective solution. Separation limits cross-subsidies between banking and proprietary trading and diminishes contagion risk, while still allowing for synergies and risk management across banking, non-proprietary trading, and proprietary trading.

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

Felix Noth Lena Tonzer

in: Applied Economics Letters, No. 7, 2017

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.

How Do Insured Deposits Affect Bank Risk? Evidence from the 2008 Emergency Economic Stabilization Act

Claudia Lambert Felix Noth Ulrich Schüwer

in: Journal of Financial Intermediation, January 2017

Abstract

This paper tests whether an increase in insured deposits causes banks to become more risky. We use variation introduced by the U.S. Emergency Economic Stabilization Act in October 2008, which increased the deposit insurance coverage from $100,000 to $250,000 per depositor and bank. For some banks, the amount of insured deposits increased significantly; for others, it was a minor change. Our analysis shows that the more affected banks increase their investments in risky commercial real estate loans and become more risky relative to unaffected banks following the change. This effect is most distinct for affected banks that are low capitalized.

On the Nonexclusivity of Loan Contracts: An Empirical Investigation

Hans Degryse Vasso Ioannidou Erik von Schedvin

in: Management Science, No. 12, 2016

Abstract

We study how a bank's willingness to lend to a previously exclusive firm changes once the firm obtains a loan from another bank ("outside loan") and breaks an exclusive relationship. Using a difference-in-difference analysis and a setting where outside loans are observable, we document that an outside loan triggers a decrease in the initial bank's willingness to lend to the firm, i.e., outside loans are strategic substitutes. Consistent with concerns about coordination problems and higher indebtedness, we find that this reaction is more pronounced the larger the outside loan and it is muted if the initial bank's existing and future loans retain seniority and are protected with valuable collateral. Our results give a benevolent role to transparency enabling banks to mitigate adverse effects from outside loans. The resulting substitute behavior may also act as a stabilizing force in credit markets limiting positive comovements between lenders, decreasing the possibility of credit freezes and financial crises.

Foreign Funding Shocks and the Lending Channel: Do Foreign Banks Adjust Differently?

Felix Noth Matias Ossandon Busch

in: Finance Research Letters, November 2016

Abstract

We document for a set of Latin American emerging countries that the different nature of foreign funding accessed by foreign and local banks affected their lending performance after September 2008. We show that lending growth was weaker for shock-affected foreign banks compared to shock-affected local banks. This evidence represents valuable policy information for regulators concerned with the stability and well-functioning of banking sectors.

Politics, Banks, and Sub-sovereign Debt: Unholy Trinity or Divine Coincidence?

Michael Koetter Alexander Popov

in: Deutsche Bundesbank Discussion Paper, No. 53, 2018

Abstract

We exploit election-driven turnover in State and local governments in Germany to study how banks adjust their securities portfolios in response to the loss of political connections. We find that local savings banks, which are owned by their host county and supervised by local politicians, increase significantly their holdings of home-State sovereign bonds when the local government and the State government are dominated by different political parties. Banks' holdings of other securities, like federal bonds, bonds issued by other States, or stocks, are not affected by election outcomes. We argue that banks use sub-sovereign bond purchases to gain access to politically distant government authorities.

May the Force Be with You: Exit Barriers, Governance Shocks, and Profitability Sclerosis in Banking

Michael Koetter Carola Müller Felix Noth Benedikt Fritz

in: Deutsche Bundesbank Discussion Paper, No. 49, 2018

Abstract

We test whether limited market discipline imposes exit barriers and poor profitability in banking. We exploit an exogenous shock to the governance of government-owned banks: the unification of counties. County mergers lead to enforced government-owned bank mergers. We compare forced to voluntary bank exits and show that the former cause better bank profitability and efficiency at the expense of riskier financial profiles. Regarding real effects, firms exposed to forced bank mergers borrow more at lower cost, increase investment, and exhibit higher employment. Thus, reduced exit frictions in banking seem to unleash the economic potential of both banks and firms.

Basel III Capital Requirements and Heterogeneous Banks

Carola Müller

in: IWH Discussion Papers, No. 14, 2018

Abstract

I develop a theoretical model to investigate the effect of simultaneous regulation with a leverage ratio and a risk-weighted ratio on banks‘ risk taking and banking market structure. I extend a portfolio choice model by adding heterogeneity in productivity among banks. Regulators face a trade-off between the efficient allocation of resources and financial stability. In an oligopolistic market, risk-weighted requirements incentivise banks with high productivity to lend to low-risk firms. When a leverage ratio is introduced, these banks lose market shares to less productive competitors and react with risk-shifting into high-risk loans. While average productivity in the low-risk market falls, market shares in the high-risk market are dispersed across new entrants with high as well as low productivity.

Banks Fearing the Drought? Liquidity Hoarding as a Response to Idiosyncratic Interbank Funding Dry-ups

Helge Littke Matias Ossandon Busch

in: IWH Discussion Papers, No. 12, 2018

Abstract

Since the global financial crisis, economic literature has highlighted banks’ inclination to bolster up their liquid asset positions once the aggregate interbank funding market experiences a dry-up. To this regard, we show that liquidity hoarding and its detrimental effects on credit can also be triggered by idiosyncratic, i.e. bankspecific, interbank funding shocks with implications for monetary policy. Combining a unique data set of the Brazilian banking sector with a novel identification strategy enables us to overcome previous limitations for studying this phenomenon as a bankspecific event. This strategy further helps us to analyse how disruptions in the bank headquarters’ interbank market can lead to liquidity and lending adjustments at the regional bank branch level. From the perspective of the policy maker, understanding this market-to-market spillover effect is important as local bank branch markets are characterised by market concentration and relationship lending.

Flooded Through the Back Door: Firm-level Effects of Banks‘ Lending Shifts

Oliver Rehbein

in: IWH Discussion Papers, No. 4, 2018

Abstract

I show that natural disasters transmit to firms in non-disaster areas via their banks. This spillover of non-financial shocks through the banking system is stronger for banks with less regulatory capital. Firms connected to a disaster-exposed bank with below median capital reduce their employment by 11% and their fixed assets by 20% compared to firms in the same region without such a bank during the 2013 flooding in Germany. Relationship banking and higher firm capital also mitigate the effects of such negative cross-regional spillovers.
