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.

This paper examines the impact of banks' collective liquidity mismatch policies on the stability of the financial sector. Using a novel identification strategy exploiting partially overlapping peer groups, I show that the liquidity created by individual banks is in large part driven by the liquidity transformation activity of their respective peers. Such correlated liquidity mismatch decisions are asymmetric and concentrated on the asset-side component of liquidity creation. Importantly, this strategic behavior increases both the default risk of individual institutions and overall systemic risk. From a macroprudential perspective, the results highlight the importance of explicitly regulating systemic liquidity risk.

We examine the impact of a large-scale microcredit expansion program on financial access and the transition of previously unbanked borrowers to commercial banks. Administrative data on the universe of loans to individuals show the program improved access to credit, especially in underdeveloped areas. A sizable share of first-time borrowers who need a second loan switch from microfinance institutions to commercial banks, which cream-skim low-risk borrowers and grant them larger, cheaper, and longer-term loans. These borrowers are not riskier than those already at commercial banks. The microfinance sector, together with well-functioning credit reference bureaus, help mitigate information frictions in credit markets.

(4) Completing the Banking Union with a European Deposit Insurance Scheme: Who is Afraid of Cross-subsidisation?, with Jacopo Carmassi, Sonja Dobkowitz, Johanne Evrard, Laura Parisi and Michael Wedow

R&R at the Economic Policy

This paper investigates the impact and appropriateness of establishing a 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, risk-based contributions to the DIF would be able to internalise specificities of banks and banking systems, thus facilitating tackling moral hazard and moving forward with risk sharing measures towards the completion of the Banking Union. 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.
