Abstract
Do lenders securitize or price loans in response to credit risk? Exploiting exogenous variation in regional credit risk due to foreclosure law differences along US state borders, we find that lenders securitize mortgages that are eligible for sale to the Government Sponsored Enterprises (GSEs) rather than price regional credit risk. For non-GSE-eligible mortgages with no GSE buyback provision, lenders increase interest rates as they are unable to shift credit risk to loan purchasers. The results inform the debate surrounding the GSEs' buyback provisions, the constant interest rate policy, and show that underpricing regional credit risk increases the GSEs' debt holdings.

The Disciplining Effect of Supervisory Scrutiny in the EU-wide Stress Test

Journal of Financial Intermediation,
January
2023
Abstract
Relying on confidential supervisory data related to the 2016 EU-wide stress test, this paper presents novel empirical evidence that supervisory scrutiny associated to stress testing has a disciplining effect on bank risk. We find that banks that participated in the 2016 EU-wide stress test subsequently reduced their credit risk relative to banks that were not part of this exercise. Relying on new metrics for supervisory scrutiny that measure the quantity, potential impact, and duration of interactions between banks and supervisors during the stress test, we find that the disciplining effect is stronger for banks subject to more intrusive supervisory scrutiny during the exercise. We also find that a strong risk management culture is a prerequisite for the supervisory scrutiny to be effective. Finally, we show that a similar disciplining effect is not exerted neither by higher capital charges nor by more transparency and related market discipline induced by the stress test.

The Effect of Firm Subsidies on Credit Markets
Aleksandr Kazakov, Michael Koetter, Mirko Titze, Lena Tonzer
IWH Discussion Papers,
Nr. 24,
2022
Abstract
We use project-level information for the largest regional economic development program in German history to study how government subsidies to firms affect credit markets. We identify credit market responses by considering both, bank lending and firm borrowing during 1998-2019. We find that subsidies lead to larger lending volumes without crowding out credit to non-subsidized firms. Banks that are more exposed to subsidized firms exhibit moderately higher credit risk though. Firm subsidies support lending especially when credit constraints are elevated during the years of the financial crisis.

Carbon Transition Risk and Corporate Loan Securitization
Isabella Müller, Huyen Nguyen, Trang Nguyen
IWH Discussion Papers,
Nr. 22,
2022
Abstract
We examine how banks manage carbon transition risk by selling loans given to polluting borrowers to less regulated shadow banks in securitization markets. Exploiting the election of Donald Trump as an exogenous shock that reduces carbon risk, we find that banks’ securitization decisions are sensitive to borrowers’ carbon footprints. Banks are more likely to securitize brown loans when carbon risk is high but swiftly change to keep these loans on their balance sheets when carbon risk is reduced after Trump’s election. Importantly, securitization enables banks to offer lower interest rates to polluting borrowers but does not affect the supply of green loans. Our findings are more pronounced among domestic banks and banks that do not display green lending preferences. We discuss how securitization can weaken the effectiveness of bank climate policies through reducing banks’ incentives to price carbon risk.

Zinsaufschlag oder Übertragung durch Verbriefung? Der Umgang mit Risiken im US-Hypothekenmarkt
Danny McGowan, Huyen Nguyen
Wirtschaft im Wandel,
Nr. 3,
2022
Abstract
Seit der Finanzkrise der Jahre 2007 und 2008 diskutiert die Wissenschaft darüber, wie Kreditgeber die Verbriefung von Hypotheken nutzen, um das Kreditrisiko an Dritte weiterzugeben, und wie dies zur Finanzkrise beigetragen hat. Eine aktuelle IWH-Studie betrachtet die Entscheidungssituation des Kreditgebers zwischen Risikoaufschlag und Risikoübertragung. Sie nutzt rechtliche Unterschiede in verschiedenen US-Bundesstaaten bei der Zwangsvollstreckung von Hypotheken, um daraus unterschiedliche regionale Kreditrisiken abzuleiten. Ist dieses regionale Risiko erhöht, reagieren Kreditgeber durch vermehrte Verbriefung, wenn Hypotheken zum Verkauf an halbstaatliche Agenturen (Government Sponsored Enterprises, GSE) wie Fannie Mae und Freddie Mac zugelassen sind und so gegen Ausfall versichert werden können. Bei Hypotheken, für die kein Rückkauf durch GSE infrage kommt, erhöhen die Kreditgeber dagegen die Zinsen, da sie das Kreditrisiko nicht an die Kreditkäufer weitergeben können.

Completing the European Banking Union: Capital Cost Consequences for Credit Providers and Corporate Borrowers
Michael Koetter, Thomas Krause, Eleonora Sfrappini, Lena Tonzer
European Economic Review,
September
2022
Abstract
The bank recovery and resolution directive (BRRD) regulates the bail-in hierarchy to resolve distressed banks in the European Union (EU). Using the staggered BRRD implementation across 15 member states, we identify banks’ capital cost responses and subsequent pass-through to borrowers towards surprise elements due to national transposition details. Average bank capital costs increase heterogeneously across countries with strongest funding cost hikes observed for banks located in GIIPS and non-EMU countries. Only banks in core E(M)U countries that exhibit higher funding costs increase credit spreads for corporate borrowers and contract credit supply. Tighter credit conditions are only passed on to more levered and less profitable firms. On balance, the national implementation of BRRD appears to have strengthened financial system resilience without a pervasive hike in borrowing costs.

BigTech Credit, Small Business, and Monetary Policy Transmission: Theory and Evidence
Yiping Huang, Xiang Li, Han Qiu, Dan Su, Changhua Yu
IWH Discussion Papers,
Nr. 18,
2022
Abstract
This paper provides both theoretical and empirical analyses of the differences between BigTech lenders and traditional banks in response to monetary policy changes. Our model integrates Knightian uncertainty into portfolio selection and posits that BigTech lenders possess a diminishing informational advantage with increasing firm size, resulting in reduced ambiguity when lending to smaller firms. The model suggests that the key distinction between BigTech lenders and traditional banks in response to shifts in funding costs, triggered by monetary policy changes, is more evident at the extensive margin rather than the intensive margin, particularly during periods of easing monetary policy. Using a micro-level dataset of small business loans from both types of lenders, we provide empirical support for our theoretical propositions. Our results show that BigTech lenders are more responsive in establishing new lending relationships in an easing monetary policy environment, while the differences in loan amounts are not statistically significant. We also discuss other loan terms and the implications of regulatory policies.

The Cleansing Effect of Banking Crises
Reint E. Gropp, Steven Ongena, Jörg Rocholl, Vahid Saadi
Economic Inquiry,
Nr. 3,
2022
Abstract
We assess the cleansing effects of the 2008–2009 financial crisis. U.S. regions with higher levels of supervisory forbearance on distressed banks see less restructuring in the real sector: fewer establishments, firms, and jobs are lost when more distressed banks remain in business. In these regions, the banking sector has been less healthy for several years after the crisis. Regions with less forbearance experience higher productivity growth after the crisis with more firm entries, job creation, and employment, wages, patents, and output growth. Forbearance is greater for state-chartered banks and in regions with weaker banking competition and more independent banks.

A Note on the Use of Syndicated Loan Data
Isabella Müller, Felix Noth, Lena Tonzer
IWH Discussion Papers,
Nr. 17,
2022
Abstract
Syndicated loan data provided by DealScan is an essential input in banking research. This data is rich enough to answer urging questions on bank lending, e.g., in the presence of financial shocks or climate change. However, many data options raise the question of how to choose the estimation sample. We employ a standard regression framework analyzing bank lending during the financial crisis of 2007/08 to study how conventional but varying usages of DealScan affect the estimates. The key finding is that the direction of coefficients remains relatively robust. However, statistical significance depends on the data and sampling choice and we provide guidelines for applied research.

Explicit Deposit Insurance Design: International Effects on Bank Lending during the Global Financial Crisis
Iftekhar Hasan, Liuling Liu, Anthony Saunders, Gaiyan Zhang
Journal of Financial Intermediation,
July
2022
Abstract
Studies find that during the 2007–2009 global financial crisis, loan spreads rose and corporate lending tightened, especially for foreign borrowers (a flight-home effect). We find that banks in countries with explicit deposit insurance (DI) made smaller reductions in total lending and foreign lending, experienced smaller increases in loan spreads, and had quicker post-crisis recoveries. These effects are more pronounced for banks heavily relying on deposit funding. Evidence also reveals that more generous or credible DI design is associated with a stronger stabilization effect on bank lending during the crisis, confirmed by the difference-in-differences analysis based on expansion of DI coverage during the crisis. The stabilization effect is robust to the use of country-specific crisis measures and control of temporary government guarantees.
