The European Central Bank (ECB) has published its first comprehensive report on whistleblowing activities within the Single Supervisory Mechanism (SSM), offering valuable insight into how reports of prudential breaches are handled.
Key Highlights
- Report Volume
Out of the SSM-related reports received in 2025, 74% were handled by National Competent Authorities (NCAs) and 26% by the ECB. Roughly 59% involved less significant institutions, while 40% pertained to significant banks under direct ECB supervision.
- Primary Concerns
63% of reports centered on internal governance, particularly weaknesses in risk management, internal controls, and the suitability of management body members. Issues like capital requirements and reporting made up 2% each.
- Channels & Anonymity
Over 80% of reports were submitted electronically, with 50% utilizing anonymous online reporting tools. Interestingly, 55% of reports came from external sources, while 45% originated from corporate insiders.
- Supervisory Action
Reports led directly to concrete follow-ups: 82% resulted in supervisory investigations or on-site inspections, 16% prompted qualitative supervisory measures (such as governance remediation), and 2% initiated formal enforcement or sanctioning proceedings.
According to these, it is evident that confidential and accessible reporting channels remain a cornerstone of effective oversight and institutional integrity across the EU financial sector.
