A new era began in early 2026 in ESG risk management for the European banking sector. The updated guidelines of the European Banking Authority (EBA) make it clear: ESG is no longer a supplementary consideration, but a fundamental element of banking operations. Institutions that delay may face not only compliance risks, but also strategic and financial risks.

The new regulation is mandatory for significant institutions from 11 January 2026, while smaller, non-complex institutions (Non-Complex Institutions – SNCIs) must comply with the requirements by early 2027 at the latest.

• ESG has become a core requirement of banking operations: the European Banking Authority (EBA) guidelines mandate full integration from 2026.
• Compliance is not just a regulatory issue: delays also pose strategic and financial risks for institutions.
• ESG risks must be fully embedded into strategy, risk management, and decision-making processes.
• Banks that act early can build a competitive advantage, while laggards may face lasting disadvantages.

What does this mean in practice?

According to the expectations of the EBA and the European Central Bank (ECB), ESG risks must be fully integrated into banks’ operations:

• ESG aspects must be reflected in strategy and business models;
• ICAAP/ILAAP processes, risk appetite and internal controls must be reviewed;
• forward-looking, short- and long-term scenario analyses become mandatory.

The regulatory approach is clear: the principle of proportionality does not mean exemption. Every institution is expected to maintain effective control over ESG risks.

The MNB recommendation distinguishes between required and best practice levels of implementation. For the required elements (which must be implemented), consequences defined in the relevant legal provisions apply if implementation is missing or inadequate.

The new role of scenario analysis: from compliance to strategic tool

The assessment of ESG risks is no longer limited to theoretical models. Banks must quantify impacts:

• in short-term stress tests (capital and liquidity);
• in climate and nature-related risk analyses with a minimum 10-year horizon;
• in dynamic balance sheet models that take into account transition pathways and changes in client behaviour.

ESG risks affect all traditional risk categories – from credit risk to operational risks – therefore scenario analysis has become a key tool for long-term resilience.

Double materiality: risk management on new foundations

Supervisory expectations require banks to go beyond climate risks and integrate the full spectrum of ESG into their operations.

A central element of this is the principle of double materiality, which:

• requires regular (at least annual) materiality assessments;
• demands deeper understanding of client and sector exposures;
• presupposes data-driven risk assessment and reporting.

This approach provides a more accurate picture of financial exposures and strategic vulnerabilities, while also requiring new capabilities and operating models.

The biggest challenge: data and processes

Experience shows that many institutions are not yet fully prepared. However, from a supervisory perspective, this is no longer an acceptable justification.

Banks are expected, among others, to:

• improve data quality and eliminate data gaps;
• define clear responsibilities for ESG risk management;
• integrate ESG into lending processes, onboarding and monitoring;
• establish transparent reporting structures and KPI/KRI systems.

Supervisors will actively assess whether institutions are truly capable of managing these risks.

There is a tight deadline of approximately four months between the publication and application of the final MNB recommendation (except for the transition plan, which has a deadline of 1 January 2027). The new recommendation has a strong risk management focus and is geared towards preparing transition plans. Institutions whose parent banks already have such plans will find it easier to meet the expected deadlines.

Why act now?

The message is clear: institutions that invest in a robust ESG framework in time:

• reduce supervisory risks;
• strengthen their strategic position;
• and build a competitive advantage in a rapidly changing market.

Delay, on the other hand, may result not only in compliance issues, but also in business disadvantages in an environment where regulators, clients and investors are raising their expectations.
