A real‑world audit‑trail crisis at a regional bank
Mid‑size Bank XYZ, a $12 billion regional lender, was surprised during its March 2026 OCC examination. The examiner requested immediate proof of transaction‑level evidence for a set of high‑risk loan approvals. Bank XYZ could only produce scattered spreadsheets and paper records, forcing the examiner to issue a conditional finding and delay the final rating.
The bank’s Chief Data Officer realized the core issue was not data quality but an incomplete audit‑trail: no single system logged the end‑to‑end flow of data, approvals, and controls, and the evidence could not be produced on demand. The examiner’s note read, “Bank must develop a reliable, examiner‑ready audit trail to demonstrate compliance with OCC expectations.” This incident illustrates a growing regulator focus on real‑time evidence readiness rather than static attestations.
The evidence‑readiness problem
Regulators are shifting from periodic reports to continuous, examiner‑ready evidence. The OCC’s February 2026 bulletin (OCC 2026‑15) on audit‑trail readiness explicitly states that banks must maintain immutable logs of data transformations and provide instant access to supporting documentation during examinations.
Legacy data‑governance programs, built around annual certifications and manual evidence gathering, cannot satisfy this demand. Gaps arise when data lineage is fragmented across silos, control owners store evidence in disparate folders, and there is no automated way to assemble a complete evidence package. The stakes are high: examiners can issue conditional findings, fines, or enforcement actions, and banks risk reputational damage and increased supervisory scrutiny.
The CoComply approach
CoComply bridges the gap by turning data‑governance into a live, AI‑verified evidence engine.
First, our platform continuously maps data lineage across all systems, creating an immutable, time‑stamped audit trail for every critical data asset. This includes automatic capture of data transformations, approvals, and control point events, ensuring no transaction falls through the cracks.
Second, CoComply’s AI agents collect, tag, and store control evidence in a searchable repository, automatically linking each piece of evidence to the relevant control and regulator requirement. The AI also validates evidence completeness, flags gaps, and suggests remediation steps before an exam even begins.
When an examiner requests proof, the platform assembles a complete, examiner‑ready evidence package in seconds, complete with cryptographic proof of integrity. This eliminates the manual rummaging through spreadsheets and ensures the bank can demonstrate compliance in real time, directly addressing the OCC’s new audit‑trail expectations.
Expanding the impact of continuous evidence
Beyond the immediate exam, continuous audit‑trail readiness supports internal risk management, audit planning, and board reporting. By having a single source of truth, banks can run scenario analyses, assess control effectiveness, and quickly respond to emerging regulatory trends without costly data‑reconciliation projects.
Moreover, CoComply’s architecture is designed for scalability. Whether a bank handles thousands of daily loan approvals or millions of retail transactions, the platform’s distributed ledger ensures performance and resilience, while maintaining the same examiner‑ready standard across all lines of business.
Closing thoughts on examiner‑ready evidence
The OCC’s 2026‑15 bulletin signals a permanent shift: auditors will expect instant, verifiable audit trails, not periodic snapshots. Banks that continue to rely on manual evidence collection will face repeated conditional findings and costly remediation. By embedding continuous lineage and AI‑driven evidence collection into daily operations, CoComply empowers banks to meet examiner expectations today and future‑proof their governance against evolving regulatory demands.
