Europe’s three financial regulators have published joint guidelines to unify and strengthen ESG risk assessment through supervisory stress testing, with a planned implementation from 2027 amid efforts to harmonise methodologies across the single market.
Europe’s three supervisory authorities have published finalised joint guidelines to help national banking and insurance supervisors embed environmental, social and governance (ESG) risks into supervisory stress testing, setting out a common methodology and timetable for adoption across the EU.
According to a press release by the European Banking Authority (EBA), the guidelines, issued jointly by the EBA, the European Insurance and Occupational Pensions Authority (EIOPA) and the European Securities and Markets Authority (ESMA), provide clear direction on how competent authorities should integrate ESG risks either within existing supervisory stress‑testing frameworks or via complementary assessments that measure the impact of ESG risks under adverse scenarios. The agencies say the work aims to harmonise methodologies and practices so that supervisors apply a consistent approach to ESG stress testing across the financial system.
The guidelines were prepared under mandates in the Capital Requirements Directive and the Solvency II Directive, the EBA notes, and follow a public consultation that ran until 19 September 2025, organised by EIOPA.
Risk‑based, proportionate approach
The text urges competent authorities to adopt a risk‑based approach, beginning with a materiality assessment to identify the most relevant ESG vulnerabilities for each supervised entity. Factors to consider include business model, portfolio composition, geographic exposures and sectoral activity across multiple time horizons. The ESAs advise supervisors to prioritise climate and other environmental risks , both physical and transition risks , with a gradual extension to other ESG dimensions such as biodiversity loss, pollution, social and governance risks as data and modelling capabilities improve.
The guidelines distinguish between objectives that require short‑term time horizons , assessing financial resilience to adverse but plausible shocks , and longer‑term horizons aimed at testing the resilience of business models and strategies. They also set out considerations for scenario design, the relative merits of top‑down versus bottom‑up approaches, and the appropriate level of granularity, including portfolio, sectoral, geographic and counterparty‑level analysis.
Supervisory expectations and resources
While the ESAs emphasise harmonisation, they stress that the guidelines do not create new legal obligations on competent authorities to run ESG‑focused supervisory stress tests; they are instead subject to a “comply or explain” mechanism under which national authorities must either follow the guidance or publicly justify divergences. The EBA press release underlined that authorities should apply the guidelines proportionately, in line with sectoral rules.
The joint documents also call on supervisors to ensure they have sufficient human and technical resources to conduct robust ESG stress testing, including staff with ESG expertise and adequate data‑management capabilities to access high‑quality ESG data. Industry data and stakeholder feedback during the consultation highlighted persistent gaps in data and modelling that supervisors will need to address to implement the approaches envisaged.
Implementation timetable
The ESAs said the joint guidelines will apply from the beginning of 2027, giving national competent authorities time to adapt their supervisory toolkits and to build up the data and modelling capacity required to undertake both integrated and complementary ESG stress‑testing exercises.
The publication marks a coordinated step by EU supervisors to bring ESG risks into mainstream prudential practice while leaving room for proportionality and national discretion. According to the agencies, the intention is to create common standards that raise the overall quality and comparability of ESG stress testing across the single market, even as the approach evolves with improving data and modelling techniques.

These guidelines provide national insurance and banking supervisors with clear guidance on integrating ESG risks into supervisory stress tests, both within established frameworks and through complementary assessments of ESG risk impacts. The guidelines aim to harmonise methodologies and practices across the EU’s financial system, ensuring consistent integration of ESG risks into national supervisory stress testing activities. Importantly, they do not introduce new requirements for competent authorities to conduct ESG-focused supervisory stress tests.

They aim to harmonise methodologies and practices among supervisors in banking and insurance, to ensure proportionality and to enhance the effectiveness and efficiency of ESG stress testing. The guidelines are addressed to competent authorities and should be applied when performing supervisory stress tests, either by integrating ESG-related risks into their existing framework or by measuring the impact of ESG risks under adverse scenarios in a complementary assessment, where applicable according to the sectoral legislation.

They aim to harmonise methodologies and practices among supervisors in banking and insurance, to ensure proportionality and to enhance the effectiveness and efficiency of ESG stress testing.

- https://www.esgtoday.com/eu-financial-regulators-release-guidelines-for-integrating-esg-risks-into-stress-tests/ – Europe’s three primary financial regulatory agencies, the European Supervisory Authorities (ESAs), announced the publication of their finalized Guidelines on environmental, social, and governance (ESG) stress testing, aimed at enabling national regulators to integrate ESG risks into their supervisory stress tests for banks and insurance companies. The ESAs include The European Securities and Markets Authority (ESMA), The European Banking Authority (EBA), and The European Insurance and Occupational Pensions Authority (EIOPA). According to the ESAs, the new guidelines are designed to establish common standards for embedding ESG risks into stress testing methodologies across the EU’s financial system, ensuring that competent authorities consistently integrate ESG risks into their national supervisory stress testing activities, and encompass the integration of ESG risks into existing frameworks, as well as new complementary assessments for measuring the impact of ESG risks under adverse scenarios. While not creating any new requirements for regulators, the ESAs said that the new guidelines will be subject to a “comply or explain” procedure by the National Competent Authorities. Among the key factors covered by the new publication is guidance for competent authorities to adopt a risk-based approach to their integration of ESG risks, starting with a materiality assessment to identify the most relevant and impactful risks, considering issues such as financial entities’ business model, portfolios, geographic exposures, and sectoral activities over various time horizons. The new guidelines propose that authorities first focus on climate and environmental risks, including both physical and transition risks, and to gradually extend coverage to other ESG factors, based on factors including the availability of data and the use of models developed over time. Additional factors included in the new guidelines include time horizon, with regulators guided to use a short-term time horizon when assessing financial resilience to adverse but plausible shocks, and a longer-term horizon for assessing the resilience of financial entities’ business models and strategies, as well as scenario designs, and considerations for the use of top-down vs bottom-up approaches, as well as level of granularity, with regulators guided to consider portfolio, sectoral, geographical, and counterparty-level dimensions, and to perform separate identification of physical risks, transition risks, and other ESG factors such as biodiversity loss, pollution, social and governance risks. The guidelines also recommend that regulators allocate sufficient human and material resources to the ESG risk stress testing process, including involving staff with expertise in ESG risk assessment, and having data management and collection capabilities in place to support access to high-quality ESG data. The ESAs said that the new joint guidelines will apply from the beginning of 2027.
