Property Value Assessment Under EU Banking Regulation

A methodological framework for real estate collateral under CRR3, taking into account the International Valuation Standards (IVS) and relevant ESG factors, including physical and environmental risks, in determining prudential value. The study includes illustrative numerical applications to property resilience and physical risks. This paper examines the methodological implications of property value (PV) under Article 229 of Regulation (EU) 2024/1623, which, in implementation of the Basel III framework, amended Regulation (EU) No 575/2013 on prudential requirements for credit institutions and investment firms, for real estate collateral valuation (CRR3). It considers how current market value (MV) may be tested against the value sustainable over the life of the loan, with particular attention to property resilience, energy efficiency and materially relevant environmental and physical risks. The study combines the CRR3 framework, European Banking Autority (EBA) Guidelines and European Central Bank (ECB) Good Practices with valuation standards and a targeted critical review of recent literature. Drawing on the IVS and the Italian property valuation standard, it proposes a market-capped and sustainability-tested framework for determining property value, in which risk-adjusted market value (MVRA) is used as an analytical variable to identify residual risk not already reflected in market prices. The Aphys formulation provides a first-order analytical representation of event-based physical and environmental risk adjustments through probability, uninsured property damage, property-level loss of use, non-overlapping restoration costs, discounting, and a residual-risk coefficient intended to control double counting. The framework is then applied to three hypothetical numerical worked cases in different Italian Regions: a residential property exposed to hydraulic risk in Emilia-Romagna, an income-producing commercial property exposed to seismic risk in the Marche, and a residential property with partial seismic improvement in Sicily (Messina). The cases include structured comparable analysis, illustrative scenario parameterization, and multivariate sensitivity analysis. They illustrate the computational mechanics and internal consistency of the proposed framework but do not constitute empirical calibration, validation, or evidence of real-world predictive performance; the residual-risk parameters still require calibration using observed market, hazard, vulnerability, insurance, and loss data. The framework may affect the exposure-to-value ratio (ETV) and, depending on the applicable prudential treatment, risk-weighted exposure amounts. The broader ESG perimeter recognized by valuation standards is also acknowledged: Social and Governance variables are not numerically parameterized in the three worked cases, but, where material, they should be mapped to transparent and non-duplicative valuation channels.
