Managed a 9-month ECB on-site inspection of IRB models for a major European G-SIB, delivering zero critical findings through real-time ECB engagement and targeted remediation.
The ECB announced a comprehensive on-site inspection (OSI) of the client's Credit Risk IRB models — covering RWA calculation methodologies, validation frameworks, governance, and data quality across 14 IRB portfolios spanning corporate, retail, retail mortgage, and SME segments. This was a high-stakes examination: the inspection team comprised 8 ECB specialists with direct model risk expertise, and the bank knew that findings could trigger supervisory capital adjustments or temporary RWA restrictions. The client had 6 weeks to achieve inspection readiness.
We stepped in as the bridge between the bank's internal teams and the ECB inspection team. We deployed the Ezelman FORTRESS™ framework — eight defensive positions an OSI must hold from D-120 through the ITR response.
Governance, model inventory, data lineage across 14 IRB portfolios — mapped before kickoff.
JST pre-alignment in week 2 surfaced the 3 most sensitive portfolios early.
Mock inspection 5 weeks before kickoff — 60+ information packages stress-tested.
Single evidence taxonomy across credit, model, data, IT. Inspector requests fulfilled in hours.
Daily cadence — liaison, 2LoD, business, IT. One voice at every ECB meeting.
Versioned, access-controlled data room; every document pre-cleared by legal and risk.
The 2 minor findings were reframed as remediation commitments, not methodology errors.
ITR remediation delivered in full. Capability institutionalised — zero repeat findings in 2024 follow-up.
The FORTRESS positions manifested in three day-to-day mechanics:
We conducted a 4-week rapid assessment of all 14 IRB portfolios, identifying gaps vs. ECB expectations (based on recent inspection findings across SSM-supervised banks). We prepared 60+ information packages (model documentation, validation reports, governance records) organized to ECB's request structure.
We attended 18 on-site inspection meetings, managing technical Q&A sessions with ECB specialists. When inspectors challenged a model methodology or data assumption, we fielded the response in real time, often drafting written clarifications within 24 hours.
For each portfolio, we assembled a "compliance package" documenting methodology, validation, governance, and historical performance. This evidence was pre-packaged to address the five core ECB inspection modules: Model Documentation, Validation, Data Quality, Governance, and RWA Tracking.
When the inspection team raised preliminary findings (15 observations, 2 minor findings), we coordinated remediation with the bank's internal teams, drafted corrective action plans, and validated fixes before submission to the ECB.
Rapid gap assessment and information package preparation. We reviewed each IRB portfolio against ECB's IRB inspection manual and recent findings from peer inspections. Key outputs: a 120-page pre-inspection briefing document, portfolio risk rankings (to focus ECB time on material areas), and a 15-item remediation backlog for quick wins before the inspection started.
Eight weeks of intensive on-site work. The ECB team worked on-site at the bank, with daily standups chaired by our senior advisor. We managed the "rhythm" of inspection: morning ECB team coordination, afternoon substantive technical discussions, evening evidence package preparation. We tracked 350+ data requests from inspectors and resolved 95% within 24 hours. When ECB found methodology gaps, we provided interpretation, proposed solutions, and documented the supervisor's acceptance real-time.
ECB issued a preliminary findings letter with 2 minor findings and 15 observations. We coordinated remediation workstreams, drafted corrective action plans with timeline commitments, and validated fixes with the bank's validation team before re-submitting to the ECB. All issues were resolved within 6 weeks.
ECB observed a decline in LGD estimates in the current cycle without documented stress scenario analysis. Remediation: We worked with the bank's model risk team to enhance LGD documentation, implement forward-looking economic assumptions, and add cycle-aware sensitivity analysis. Complete within 8 weeks. Status: CLOSED.
Inspectors identified gaps in end-to-end data validation for one retail segment. Remediation: We designed a data reconciliation protocol (source-to-model traceability), implemented daily data validation checks, and created a data risk dashboard for the Chief Data Officer. Implemented within 12 weeks. Status: CLOSED.
120-page readiness report covering all 14 portfolios, gap analysis vs. ECB expectations, and a remediation prioritization framework.
60+ compliance documents (model documentation, validation reports, governance records) pre-organized to ECB inspection request structure.
Real-time request tracking, 24-hour evidence delivery, daily index updates. Response rate: 95% within 24 hours.
Two detailed CAPs addressing the findings, with timeline commitments, responsible parties, and validation checkpoints.
Six training sessions for the bank's Model Risk team on ECB inspection expectations, IRB best practices, and supervisory communication protocols.
12-month enhancement plan addressing observations and strengthening governance for the next inspection cycle.
The inspection concluded successfully:
