We study how deposit competition affects a bank's decision to securitize mortgages. Exploiting the state-specific removal of deposit market caps across the U.S. as a source of competition, we find a 7.1 percentage point increase in the probability that banks securitize mortgage loans. This result is driven by an 11 basis point increase in deposit costs and corresponding reductions in banks' deposit holdings. Our results are strongest among banks that rely more on deposit funding. These findings highlight a hitherto undocumented and unintended regulatory cause that motivates banks to adopt the originate-to-distribute model.

This study employs bilateral data on external assets to examine the impact of climate policies on the reallocation of international capital. We find that the stringency of climate policy in the destination country is significantly and positively associated with an increase in the allocation of portfolio equity and banking investment to that country. However, it does not show significant effects on the allocation of foreign direct investment and portfolio debt. Our findings are not driven by valuation effects, and we present evidence that suggests diversification, suasion, and uncertainty mitigation as possible underlying mechanisms.

Im September 2025 reisten Finanzökonomen aus aller Welt zum elften Mal nach Halle, um am jährlichen FIN-FIRE-Workshop am IWH teilzunehmen. Zwei Tage lang gaben die Autoren von zehn Beiträgen einen umfassenden Überblick über aktuelle Themen, die potenzielle Herausforderungen für das Finanzsystem darstellen, z. B. mangelnden Datenschutz bei der Vergabe von Immobilienkrediten, Unsicherheiten in Anleihemärkten aufgrund von Klimarisiken, Intransparenz bei synthetischen Risikotransferprodukten, die Auswirkungen geopolitischer Risiken auf die Kreditvergabe sowie granulare Friktionen bei der Transmission geldpolitischer Maßnahmen. Ein intensiver Gedankenaustausch zwischen Autoren, Ko-Referenten und Plenum führte zu neuen Erkenntnissen über die Widerstandsfähigkeit und Fragilität unserer Finanzsysteme.

Syndicated loan data provided by DealScan is an essential input in banking research to answer urging questions on bank lending, e.g., in the presence of financial or geopolitical 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.

This paper examines the impact of climate risks on the debt structure of a sample of U.S. firms from 2002 through 2020. Climate risks—mainly physical, regulatory, and transition risks—are associated with a concentrated debt structure for the affected firms. However, when climate risks propagate through the channels of expected bankruptcy costs and sustainability, they are associated with a more diversified debt structure. Additionally, climate risks asymmetrically impact the relationship between access to finance and debt structure. Results from a quasi-natural experiment reaffirm the impact of climate risks on debt structure.
