Estonia adopts EBA climate scenario-analysis rules for banks

Estonian credit institutions must prepare for comply-or-explain supervisory expectations on environmental scenario analysis from 1 January 2027FI. Finantsinspektsioon has issued the EBA Guidelines on environmental scenario analysis (EBA/GL/2025/04, final report of 5 November 2025) as a Finantsinspektsiooni soovituslik juhend, and the guideline page states the effective date of 1 January 2027. Under Article 16(3) of the EBA founding regulation, competent authorities and financial institutions must make every effort to comply with EBA guidelines by incorporating them into their practices as appropriate. Competent authorities across the Union must notify the EBA whether they comply or intend to comply by 16 March 2026FI; silence counts as non-compliance, and notifications are published.

The guidelines specify the criteria institutions use to set the scenarios that test their resilience to long-term negative impacts of environmental factors, starting with climate-related factors, under Article 87a(3) and (5)(d) of the capital requirements directive. They complement the EBA Guidelines on the management of ESG risks (EBA/GL/2025/01) on the scenario-analysis side and the EBA Guidelines on institutions' stress testing (EBA/GL/2018/04), and they specify for IRB institutions how physical and transition climate-risk drivers enter credit-risk internal stress-test scenarios under Article 177(2a) of Regulation (EU) No 575/2013. Addressees are competent authorities and institutions within the meaning of Article 4(1)(3) of that regulation.

Institutions must use scenario analysis to identify business risks and opportunities, assess portfolio vulnerability to physical and transition risks, support strategy and transition planning, and challenge the resilience of the business model over the long term. Two complementary tools are prescribed: the short-term stress test of capital and liquidity resilience to environmental shocks, and the medium-to-long-term resilience analysis of the business model. A credible reference narrative endorsed by senior management, applied consistently across the organisation and regularly reviewed, anchors the exercise, with cross-functional input and full documentation of scenarios, assumptions, proxies and conclusions.

Scope is deliberately narrowed to environmental risks with priority to climate; social and governance factors are excluded for now because data and methodologies are not mature enough, though future revisions may add them. Proportionality runs on materiality first: small and non-complex institutions may rely on a predominantly qualitative approach for both horizons, other non-large institutions may use sensitivity analysis for short-term resilience testing, and large institutions may start with simplified approaches for long-term and non-climate analysis while building quantitative capability. Transmission channels from environmental drivers to exposures must be identified through a structured, documented, regularly reviewed process.

For Estonian compliance and risk officers the practical consequence is a fixed runway: the 1 January 2027 application date leaves one planning cycle to embed scenario analysis into strategy, governance, risk management and operations. The guideline takes effect in Estonia as supervisory expectation on 1 January 2027FI, with the EBA compliance notification closing on 16 March 2026FI.
