We introduce a model of the banking sector that formally incorporate a buffer function of capital. Heterogeneous banks choose their portfolio risk, bank size, and capital holdings. Banks voluntarily hold equity when the buffer effect against the risk of default outweighs the cost advantages of...

This paper examines the impact of issuing contingent convertible (CoCo) bonds on bank risk. I apply a matching-based difference-in-differences approach to banklevel data for 246 publicly traded European banks and 61 CoCo issues from 2008−2018. My estimation results reveal that issuing CoCo...

We examine the impact of the recently introduced Basel III countercyclical capital buffer (CCyB) on foreign lending activities of Canadian banks. Using panel data for the six largest Canadian banks and their foreign activities in up to 94 countries, we explore the variation in CCyB rates across...

How do banks set their target capital ratio? How do they adjust to reach it? This paper answers these questions using an original dataset of capital ratio targets directly announced to investors by European banks, materially improving data quality compared to usual estimated implicit target. It...

Basel III regulation intent is to increase the resiliency of banks through effective risk management practices that can reduce significant idiosyncratic operational losses. A systemic risk event that leads to significant losses in a bank holding company (BHC) can expose them to become insolvent...

The bank recovery and resolution directive (BRRD) regulates the bail-in hierarchy to resolve distressed banks without burdening tax payers. We exploit the staggered implementation of the BRRD across 15 European Union (EU) member states to identify banks’ capital cost and capital structure...

The study aims to investigate the effect of conventional capital ratio, risk-based capital ratio, and capital buffer ratio on commercial bank risk-taking over the period from 2002 to 2019 using a two-step GMM method. The finding reveals that there is a positive relationship between traditional...

In this paper, we estimate the sustainable level of lifetime expected credit losses and provisions and assess the procyclicality of banks' credit losses and provisions in the Czech Republic. Further, we discuss the implications of the results for provisioning in stage 3 under the IFRS 9. Based...

We evaluated the effects of the bank levy (BL) on the profitability of commercial banks and the balance sheet reconstruction, and the shifting of banks' activities into countries with lower BL rates after BL introduction. Moreover, we investigated the effects of the Basel III and Single...

Basel III, regulating the solvency of banks, is to be fully implemented by 2027 while Solvency III directed at insurers is being prepared. In view of past experience, it will be closely modelled after Basel III. This raises two questions. (i) Will Basel III and Solvency III be more successful...

EU legislators mandated the European Banking Authority to propose a stress scenario methodology for capitalising non-modellable risk factors (NMRF) as foreseen under the Basel Fundamental Review of the Trading Book (FRTB) rules for market risk. In this paper, we present the foundations of such a...

Capital requirements involve a trade-off between financial intermediation and financial stability. I analyze this trade-off in a macroeconomic model that allows for systemic bank runs, à la Gertler and Kiyotaki (2015). I show that fixed capital requirements make the economy more prone to runs...

A growing body of literature has highlighted two important caveats to the credit-to-GDP gap as advocated by the Bank for International Settlements (BIS). The first relates to the approach used to normalise credit (i.e. dividing nominal credit by GDP). In this regard, critics have argued that GDP...

We analyse the impact of the Liquidity Coverage Ratio (LCR) on the demand for central bank reserves in the euro area with difference-in-differences estimation techniques. Using a novel dataset and an identification strategy that exploits the cross-country heterogeneity in the regulatory...

In many standard derivation and presentations of risk measures like the Value-at-Risk or the Expected Shortfall, it is assumed that all the model's parameters are known. In practice, however, the parameters must be estimated and this introduces an additional source of uncertainty that is usually...

The Global Financial Crisis fostered the design and adoption of macroprudential policies throughout the world. This raises important questions for monetary policy. What, if any, is the relationship between monetary and macroprudential policies? In particular, how does the effectiveness of...

The first part of this report reviews the different channels of transmission of financial shocks (including regulatory changes) highlighted in the literature in the past 15 years. While a very large number of new models have been made available since the Committee's assessment of the long-term...

Using a difference-in-differences approach and relying on conftdential supervisory data and an unique proprietary data set available at the European Central Bank related to the 2016 EU-wide stress test, this paper presents novel empirical evidence that supervisory scrutiny associated to stress...

This research intends to explore the relationship between capital buffer, nominator effect, denominator effect, and economic growth for large insured commercial banks of the USA. The study applied a two-step system Generalized Method of Moment (GMM) framework by taking the unique and...

We build a stylized dynamic general equilibrium model with financial frictions to analyze costs and benefits of capital requirements in the short-term and long-term. We show that since increasing capital requirements limits the aggregate loan supply, the equilibrium loan rate spread increases,...

This paper deals with both system-wide and banks' internal stress tests. For system-wide stress tests it describes the evolution over time, compares the stress test design in major jurisdictions, and discusses academic research. System-wide stress tests have gained in importance and nowadays...

This article deals with the issue of managing bank credit risk using a cost risk model. Modeling of bank credit risk management was proposed based on neural-cell technologies, which expand the possibilities of modeling complex objects and processes and provide high reliability of credit risk...
