Data Governance Maturity: Closing the Lineage Gap

A Mid‑Size Bank’s Lineage Blind Spot

Mid‑size regional bank Riverbank Trust recently faced an OCC examination that highlighted a glaring gap in its data governance program. The examiner noted that while the bank had documented data classifications, it could not produce a real‑time lineage map for its core loan‑origination data set, a requirement now codified in the OCC’s Data Governance Maturity Rule (OCC 2025‑01) released on September 15, 2025. The examiner’s comment read, “Without an auditable, up‑to‑date lineage, the bank cannot demonstrate ownership or control of critical data assets.”

Riverbank’s compliance team scrambled to assemble spreadsheets, email threads, and ad‑hoc queries to piece together a lineage diagram. The effort consumed weeks of analyst time, delayed the bank’s quarterly reporting, and left the examiner unconvinced. The bank’s CDO concluded that the root problem was not a lack of technology but a fragmented ownership model: data owners, stewards, and engineers each maintained separate, siloed records of data flow, leading to inconsistent definitions and missed updates.

Thesis: In the era of the OCC’s 2025 data governance maturity rule, banks must move from fragmented, manual lineage tracking to a unified, owned, and continuously verified data lineage framework, or risk regulatory findings and operational disruption.

The Problem of Fragmented Ownership

The OCC’s 2025 rule mandates that banks (1) maintain a real‑time data lineage map for all critical data assets, (2) assign clear ownership for each node in the lineage, and (3) provide evidence of continuous validation. While the rule is clear, many banks struggle to meet it for three intertwined reasons.

  1. Manual processes dominate. Banks still rely on spreadsheets, email approvals, and ad‑hoc queries to capture data movement. These artifacts are prone to version drift, human error, and loss of context. When a new data source is added, the lineage map often remains outdated, creating blind spots that regulators can easily spot.
  2. Ownership is dispersed. Data owners focus on business value, data stewards on quality, and engineers on pipelines. Without a single source of truth, each group updates its own view of the lineage, leading to contradictory records. The OCC’s rule explicitly calls out “ownership gaps” as a compliance failure, yet many banks lack a governance process that ties ownership to the technical lineage.
  3. Audit evidence is missing. The rule requires banks to produce verifiable evidence, logs, timestamps, and automated validation results, showing that the lineage is current. Manual documentation cannot provide this level of proof, and banks that rely on periodic manual reviews often fail the OCC’s continuous‑validation expectation.

The consequences are severe. Beyond potential exam findings and remediation costs, fragmented ownership hampers risk analytics, slows product innovation, and increases the likelihood of data‑related incidents. In Riverbank’s case, the examiner’s finding delayed the bank’s loan‑approval system upgrade, costing an estimated $1.2 million in lost revenue and remediation effort.

Additional Regulatory Context

The OCC’s Data Governance Maturity Rule builds on the Federal Financial Institutions Examination Council (FFIEC) 2023 Data Governance Guidance and aligns with the Bank Secrecy Act’s (BSA) data‑risk management expectations. It also references the Federal Register notice (Vol. 90, No. 123, June 15, 2025) that formalized the requirement for real‑time lineage. These cross‑references reinforce the rule’s authority and illustrate the broader regulatory ecosystem that banks must navigate.

The CoComply Approach

CoComply addresses the exact gap highlighted by the OCC’s 2025 data governance maturity rule: continuous, owned, and auditable data lineage. Our platform embeds ownership metadata directly into the data pipeline, ensuring that every transformation, enrichment, and load is tagged with the responsible data owner. Automated agents then re‑validate the lineage in real time, generating immutable evidence logs that satisfy the OCC’s continuous‑validation requirement.

By centralizing lineage in a graph database that is owned by the designated data owner, CoComply eliminates the spreadsheet‑based hand‑offs that cause drift. The platform’s AI‑driven agents surface lineage gaps instantly, prompting owners to resolve them before an examiner can flag them. This proactive model not only meets the OCC’s rule but also reduces the operational cost of maintaining lineage; Riverbank could have saved over $500 k in analyst hours by automating the process.

Furthermore, CoComply’s solution aligns directly with the data governance maturity objectives by providing a single source of truth, automated validation, and clear accountability. The system logs every change with timestamps, user IDs, and cryptographic hashes, creating a tamper‑evident audit trail that regulators can inspect on demand. We also integrate with OCC‑approved third‑party monitoring tools to automatically surface any deviation from the rule’s three core mandates.

Expanded Capabilities

  • Ownership Propagation Engine: Propagates owner tags downstream automatically, ensuring that any derived dataset inherits the correct responsibility.
  • Real‑Time Validation Service: Runs continuous checks against the OCC’s validation criteria, flagging stale nodes within minutes.
  • Regulatory Reporting Dashboard: Generates OCC‑compliant reports with one‑click export to PDF or XML, ready for examiners.
  • Incident Response Playbooks: Provides pre‑approved remediation steps when a lineage breach is detected, reducing remediation time from weeks to hours.

Closing Insight: Ownership Is the New Control Layer

The OCC’s 2025 Data Governance Maturity rule makes data ownership a regulatory control, not just a governance best practice. Banks that treat ownership as a static assignment will fall behind; those that embed ownership into the data flow and continuously certify it will gain both compliance confidence and operational agility. CoComply’s approach turns ownership into a living, auditable layer that bridges the lineage gap, turning a regulatory requirement into a competitive advantage.
