Unlocking supervisory effectiveness in credit risk: insights from the ECB’s supervisory findings and measures
This paper provides an assessment of supervisory effectiveness in credit risk using confidential data from ECB Banking Supervision. The analysis covers 8,106 supervisory measures issued and closed between 2016 and 2025. A central contribution is the construction of a measure level indicator of supervisory effectiveness based on large language model (LLM) analysis of supervisory narratives and closure justifications. The indicator captures whether supervisory measures resulted in full remediation of the underlying deficiencies.
