- Abstract
- This paper develops an agent-based framework (DeTail) to assess the state-contingent tail effects of releasable macroprudential capital buffers. The model features heterogeneous firms, households, and banks, and a single central bank, all interacting in a fully integrated, stock-flow consistent framework which generates endogenous credit cycles. Using this approach, we evaluate how time-varying capital requirements affect the time-varying distributions of credit growth, firm and household default rates, and bank losses along the credit cycle. Policy experiments show that releasing capital buffers during economic downturns preserves credit supply by improving risky (lower-tail) credit outcomes, reduces both household and firm defaults, and supports macro-financial resilience by limiting tail bank losses. At the same time, capital buffer accumulation during upturns imposes minimal costs and does not significantly constrain lending. These findings support the active use of releasable buffers to mitigate systemic risk and smooth credit cycles without weakening the banking system.

- Abstract
- We study the impact of cyclical systemic risks on banks’ profitability in the euro area within a panel quantile regression model, with the ultimate goal to inform the calibration of the Countercyclical Capital buffer (CCyB). Compared to previous studies, we augment our model to control for unobserved bank-specific characteristics and year-fixed effects and find a lower degree of heterogeneity in the estimated effects across the conditional distribution of bank returns on assets. We propose a simple yet intuitive framework to calibrate the CCyB through the cycle, including the socalled "positive neutral" rate. The model suggests a target positive neutral rate for the euro area ranging from 1.1% to 1.8%. Furthermore, the calibrated CCyB rates are consistent with the evolution of domestic cyclical systemic risks in the countries considered. The results further show that the adoption of a positive neutral CCyB approach allows for an earlier and more gradual build-up of the buffer, but does not lead to higher CCyB requirements at the peak of the cycle. Importantly, a positive neutral CCyB strategy would have implied that most euro area countries would have had a positive CCyB in place at the onset of the COVID-19 pandemic.

- Abstract
- This article discusses the possible implementation of a positive neutral rate for the countercyclical capital buffer (CCyB) as a means of increasing macroprudential policy space in the European banking union. Drawing on experience from the coronavirus (COVID-19) pandemic, it explains why a positive neutral rate is needed to enhance the effectiveness of the current macroprudential framework. It also describes recent progress on the application of this tool around the globe and concludes with some remarks on the calibration and potential future application of the tool in the banking union.

- Abstract
- This study provides a conceptual and monitoring framework for systemic liquidity, as well as a legal assessment of the possible use of macroprudential liquidity tools in the European Union. It complements previous work on liquidity and focuses on the development of liquidity risk at the system-wide level. A dashboard with a total of 20 indicators is developed for the financial system, including banks and non-banks, to assess the build-up of systemic liquidity risk over time. In addition to examining liquidity risks, this study sheds light on the legal basis for additional macroprudential liquidity tools under existing regulation (Article 458 of the Capital Requirements Regulation (CRR), Articles 105 and 103 of the Capital Requirements Directive (CRD IV) and national law), which is a key condition for the implementation of macroprudential liquidity tools.
