Internal ratings-based models play a central role in bank risk management and regulatory capital determination, yet their validation remains methodologically challenging and operationally resourceintensive. In this paper, we contribute to the quantitative validation of probability of default...

Consistent reporting of supervisory information by individual credit institutions is paramount for the integrity of the data that underpins sound financial information and regulatory capital and liquidity requirements. In this context, recent findings of severe inconsistencies in sectoral...

This paper develops an early warning system for predicting distress for large European banks. Using a novel definition of distress derived from banks' headroom above regulatory requirements, we investigate the performance of three machine learning techniques against the traditional logistic...

We introduce a new Economic Distress Index (EDI), which incorporates information from all economic sectors as a device for real-time monitoring of financial stability risks in the euro area. Our approach is based on structural models of credit risk and incorporates market and balance sheet...

The Prudential Regulation has raised the issue of estimation errors due to Internal Rating Based (IRB) estimation process that may produce underestimation of the risk measures. In the context of credit risk, lower bounds (i.e. floors) for the estimated parameters are introduced to limit the...

Stablecoin issuers can become subject to runs just like banks. This is because, in the absence of adequate regulation, issuers are incentivised to hold disproportionate amounts of high-yielding but illiquid assets in their reserve portfolios. The value of such reserve assets may be overly...

Proposals to include adjustments such as brown penalising and green supporting factors in the prudential regulation are meant to direct bank lending towards environmentally friendly projects. However, such adjustments can blur the lines between prudential credit risk assessment and environmental...

The Paris Agreement requires policy makers to keep the increase in global average temperature well below 2°C above pre-industrial levels, while pursuing efforts to limit the increase to 1.5°C. Furthermore, it demands finance flows to be consistent with pathways towards low greenhouse gas...

The level of capital requirement generated by the IRB approach depends crucially on the asset correlation, a parameter that enters the regulatory risk weight formula and is determined by the Regulators. Several studies have estimated the asset correlations and found that the empirical values are...

Article 16 of the EBA Founding Regulation enables the EBA to issue guidelines and recommendations, while Articles 8 (1) (aa) and (ab) and 29 (2) of that Regulation enable it to develop a handbook for supervision and resolution. The European Court of Justice (ECJ or Court, hereinafter), in its...
