Financial System Adaptability and Resilience

Financial systems differ across countries and tend to evolve slowly over time. Their structure is typically stable, but their resilience is often tested. A well-functioning financial system is vital for economic development, as it ensures that capital flows to the most productive and valuable investment opportunities. However, systemic vulnerabilities can have far-reaching consequences. For example, the 2007–08 global financial crisis emerged from within the financial sector itself when complex financial products fuelled a credit bubble in the U.S. housing market, threatening global economic stability when the bubble burst. That event led to extensive policy and regulatory reforms to strengthen financial system resilience.

Financial systems continue to face significant challenges. External shocks like the COVID-19 pandemic, the climate crisis, the green economic transition, and the energy crisis driven by geopolitical conflict all underscore the importance of financial systems that can absorb shocks and adapt to changing economic conditions. Motivated by these pressing issues, we investigate how financial systems respond to crises, which institutions and policies improve resilience, and the role of finance systems' setup in broader economic transformations. We use diverse data sources, including bank and firm-level data, regulatory reports, and house price and election data, to inform evidence-based policy.

OVERHANG: Debt overhang and green investments - the role of banks in climate-friendly management of emission-intensive fixed assets

The collaborative project “Debt Overhang and Green Investments” (OVERHANG) aims to investigate the role of banks in the climate-friendly management of emission-intensive fixed assets. This will identify policy-relevant insights on financial regulation, government-controlled lending and financial stability, as well as raise awareness among indebted stakeholders.

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.

Rules versus Discretion in Loan Rate Setting

Geraldo Cerqueiro Hans Degryse Steven Ongena

in: Journal of Financial Intermediation, Vol. 20 (4), 2011

Abstract

Loan rates for seemingly identical borrowers often exhibit substantial dispersion. This paper investigates the determinants of the dispersion in interest rates on loans granted by banks to small and medium sized enterprises. We associate this dispersion with the loan officers’ use of “discretion” in the loan rate setting process. We find that “discretion” is most important if: (i) loans are small and unsecured; (ii) firms are small and opaque; (iii) the firm operates in a large and highly concentrated banking market; and (iv) the firm is distantly located from the lender. Consistent with the proliferation of information-technologies in the banking industry, we find a decreasing role for “discretion” over time in the provision of small credits to opaque firms. While widely used in the pricing of loans, “discretion” plays only a minor role in the decisions to grant loans.

Staying, Dropping, or Switching: The Impacts of Bank Mergers on Small Firms

Hans Degryse Nancy Masschelein Janet Mitchell

in: Review of Financial Studies, Vol. 24 (4), 2011

Abstract

Assessing the impacts of bank mergers on small firms requires separating borrowers with single versus multiple banking relationships and distinguishing the three alternatives of “staying,” “dropping,” and “switching” of relationships. Single-relationship borrowers who “switch” to another bank following a merger will be less harmed than those whose relationship is “dropped” and not replaced. Using Belgian data, we find that single-relationship borrowers of target banks are more likely than other borrowers to be dropped. We track postmerger performance and show that many dropped target-bank borrowers are harmed by the merger. Multiple-relationship borrowers are less harmed, as they can better hedge against relationship discontinuations.

The Impact of Bank and Non-bank Financial Institutions on Local Economic Growth in China

Xiaoqiang Cheng Hans Degryse

in: Journal of Financial Services Research, Vol. 37 (2), 2010

Abstract

This paper provides evidence on the relationship between finance and growth in a fast growing country, such as China. Employing data of 27 Chinese provinces over the period 1995–2003, we study whether the financial development of two different types of financial institutions — banks and non-banks — have a (significantly different) impact on local economic growth. Our findings indicate that banking development shows a statistically significant and economically more pronounced impact on local economic growth.

Cross-border Exposures and Financial Contagion

Hans Degryse Muhammad Ather Elahi Maria Fabiana Penas

in: International Review of Finance, Vol. 10 (2), 2010

Abstract

Integrated financial markets provide opportunities for expansion and improved risk sharing, but also pose threats of contagion risk through cross-border exposures. This paper examines cross-border contagion risk over the period 1999–2006. To that purpose we use aggregate cross-border exposures of 17 countries as reported in the Bank for International Settlements Consolidated Banking Statistics. We find that a shock that affects the liabilities of one country may undermine the stability of the entire financial system. Particularly, a shock wiping out 25% (35%) of US (UK) cross-border liabilities against non-US (non-UK) banks could lead to bank contagion eroding at least 94% (45%) of the recipient countries' banking assets. We also find that since 2006 a shock to Eastern Europe, Turkey and Russia affects most countries. Our simulations also reveal that the ‘speed of propagation of contagion’ has increased in recent years resulting in a higher number of directly exposed banking systems. Finally, we find that contagion is more widespread in geographical proximities.

Lending Technology, Bank Organization and Competition

Hans Degryse Steven Ongena Günseli Tümer-Alkan

in: Journal of Financial Transformation, Vol. 26, 2009

Abstract

This paper reviews recent theoretical and empirical studies investigating how both bank technology and organization shape bank-borrower interactions. We refer to two related concepts for bank technology. First, the technologies banks employ in loan granting decisions and second, the advances in information technology linked to the bank's lending technology. We also summarize and interpret the theoretical and empirical work on bank organization and its influence on lending technologies. We show that the choice of lending technology and bank organization depend heavily on the availability of information, the technological progress in the collection of information, as well as the banking market structure and the legal environment. We draw important policy conclusions from the literature. Competition authorities and supervisors have to remain alert to the consequences of the introduction of any new technology because: (1) advances in technology do not necessarily lead to more intense banking competition, and (2) the impact of technological and financial innovation on financial efficiency and stability depends on the incentives of the entire „loan production chain.‟

What Drives Banks‘ Geographic Expansion? The Role of Locally Non-diversifiable Risk

Reint E. Gropp Felix Noth Ulrich Schüwer

in: IWH Discussion Papers, No. 6, 2019

Abstract

We show that banks that are facing relatively high locally non-diversifiable risks in their home region expand more across states than banks that do not face such risks following branching deregulation in the 1990s and 2000s. These banks with high locally non-diversifiable risks also benefit relatively more from deregulation in terms of higher bank stability. Further, these banks expand more into counties where risks are relatively high and positively correlated with risks in their home region, suggesting that they do not only diversify but also build on their expertise in local risks when they expand into new regions.

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.

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.
