This paper examines whether banks strategically incorporate their competitors’ liquidity mismatch policies when determining their own and how these collective decisions impact financial sector stability. Using a novel identification strategy exploiting the presence of partially overlapping peer groups, I show that banks’ liquidity transformation activity is driven by that of their peers. These correlated decisions are concentrated on the asset side of riskier banks and are asymmetric, with mimicking occurring only when competitors are taking more risk. Accordingly, this strategic behavior increases banks’ default risk and overall systemic risk, highlighting the importance of regulating liquidity risk from a macroprudential perspective.

We analyze the credit supply and real sector effects of bank bail-ins by exploiting the unexpected failure of a major Portuguese bank and subsequent resolution. Using a matched firm-bank dataset on credit exposures and interest rates, we show that while banks more exposed to the bail-in significantly reduced credit supply at the intensive margin, affected firms compensated the tightening of overall credit with other sources of funding. Nevertheless, SMEs were subject to a binding contraction of funds available through credit lines and reduced investment and employment. These dampening effects are explained by the pre-shock internal liquidity position of smaller firms.

We examine the impact of a large-scale microcredit expansion program on financial access and the transition of previously-unbanked borrowers to commercial banks. Using administrative data on the universe of loans from a credit register accessible to all lenders, we show that the program improved access to credit, especially in underdeveloped areas, with positive effects on business and mortgage lending. The program also generated positive spillovers to the commercial banking sector. As the newly-created microfinance institutions (MFIs) faced lending constraints, a sizable share of first-time borrowers obtained subsequent loans—that were larger, cheaper, and longer-term—from commercial banks, which expanded their branch network in under-served low-risk areas. The individuals switching from MFIs to banks were less risky than non-switchers and not riskier than existing bank borrowers. Overall, our results suggest that the microfinance sector, coupled with a credit reference bureau, can mitigate information frictions in credit markets and serves as a pathway for first-time borrowers to commercial banks.

(4) Completing the Banking Union with a European Deposit Insurance Scheme: Who is Afraid of Cross-subsidisation?, with J. Carmassi, S. Dobkowitz, J. Evrard, L. Parisi, and M. Wedow
R&R (2nd round) at the the Economic Policy
This paper investigates the impact and appropriateness of establishing a fully mutualised European Deposit Insurance Scheme (EDIS) using a unique supervisory micro-level dataset on euro area banks’ covered deposits and other liabilities. Our main findings are as follows: first, an ex-ante funded Deposit Insurance Fund (DIF,) with a target size of 0.8% of euro area covered deposits, would be sufficient to cover losses even in a severe banking crisis. Second, we show possible ways of calibrating risk-based contributions to the DIF according to different sets of bank-specific and country-specific factors: this would allow taking into account the relative riskiness that they pose to EDIS, thus contributing to addressing moral hazard concerns stemming from moving from national to a European scheme. Third, smaller and larger banks would not excessively contribute to EDIS relative to the amount of covered deposits in their balance sheet. Finally, there would be no unwarranted systematic cross-subsidisation within EDIS in the sense of some banking systems systematically contributing less than they would benefit from the DIF.
