Stress testing has evolved from a routine compliance task into a central pillar of supervisory strategy, according to the head of a stress testing team at a central bank. She highlights how modern stress tests now drive risk identification, capital planni
Traditionally stress testing has been seen a procedural function of risk management – something innately routine, a small cog in a far larger machine of risk analysis.
Yet for one of Europe’s leading stress test experts in financial services within Europe, treating it as a compliance tool fails to recognise its wider strategic value.
A senior head of division at a leading central bank instead sees stress testing as an evolving instrument of risk identification, prudence, and strategic foresight in banking supervision.
Reflecting on the establishment of the Single Supervisory Mechanism (SSM), the official explained how the inaugural comprehensive assessment – comprising an Asset Quality Review and a stress test – revealed a €25 billion capital shortfall across significant institutions.
This, the executive says, spurred the central bank to develop greater rigor in its risk management practice, leading it to institutionalize stress testing as an annual exercise – something it quickly recognised as being central to a corporate understanding of the resilience of banks facing adverse scenarios.
Far from being a routine requirement, these exercises now serve as a critical input into the Supervisory Review and Evaluation Process (SREP) and help calibrate the Pillar 2 Guidance (P2G), a non-binding but influential capital recommendation.
In the remarks, the official highlighted that the central bank’s stress testing framework is built on two principal pillars: the biennial region-wide stress tests coordinated by the relevant banking authority and thematic tests conducted in alternate years.
These thematic exercises are driven by supervisory priorities, macroeconomic developments, and emerging vulnerabilities.
Past themes have included climate risk and, more recently, cyber resilience, developed in close cooperation with the central bank’s non-financial risk division.
The official emphasized the importance of integrating supervisory stress tests with other supervisory activities, such as recovery and resolution planning and thematic reviews, including recent work on commercial real estate.
She also stressed the fact that beyond the headline numbers, the real value lies in improving banks’ internal capabilities – how they embed stress testing into their strategic decision-making and governance processes.
The central bank’s stress testing methodology, while standardized for comparability, allows for proportionality in scope and complexity.
For example, smaller SSM banks participate in central bank-led stress tests using a simplified framework, whereas larger banks fall under the banking authority-led process. A critical element of this framework is quality assurance.
