Banks already run inside the strictest model-risk regime in the world: SR 11-7 model risk management at US institutions, BCBS 239 on risk data aggregation, EBA loan origination guidelines, and DORA digital operational resilience. Every AI build inherits that audit machinery on day one. Every output Impetora ships in this category carries a citation back to the source it came from, so a reviewer can rebuild any decision in seconds. *Updated 2026-04-28. By Impetora.* ## Key metrics - **SR 11-7** - Federal Reserve model risk management standard - **0.4%** - Field-level extraction error rate (production target) - **100%** - Decisions written to the audit log - **4 wk** - First-pilot deployment window ## What does document processing in banking actually look like? Document processing AI in a regulated workflow turns unstructured paperwork (contracts, claims packets, statements, referral letters, bills of lading) into structured fields, classifications, and routed records, with the source page, paragraph, and clause cited on every output. The accuracy benchmark we measure against is field-level extraction error rate; the regulatory benchmark is whether a reviewer can rebuild the decision in seconds. Banks already run inside the strictest model-risk regime in the world: SR 11-7 model risk management at US institutions, BCBS 239 on risk data aggregation, EBA loan origination guidelines, and DORA digital operational resilience. Every AI build inherits that audit machinery on day one. The pipeline is the same shape across every Impetora document processing build: Ingest -> Layout-aware OCR -> Structured extraction -> Validation rules -> Citation chain -> Human review -> Audit trail. Each stage is observable, each stage writes to the audit log, and each stage has a measurable failure mode the readiness sprint defines before any model is selected. ## What regulations apply? EU AI Act Article 6; EBA Guidelines on loan origination and monitoring (EBA/GL/2020/06); BCBS 239 risk data aggregation; SR 11-7 model risk management; DORA on third-party tech provider oversight. [1] Article 6(3) preparatory-task carve-out covers most KYC and statement OCR workflows. SR 11-7 still treats the extraction model as a model and requires lifecycle documentation; we ship that scaffolding by default. Every system Impetora ships carries the AI register entry, the risk classification, and the underlying analysis with it. A regulator or an internal audit team sees the full chain on a single page. ## What does TRACE require here? Trust. EU data residency, EU AI Act risk classification documented, GDPR by default [8], sectoral regulator framing recorded inside the AI register. Readiness. Banking workflows are sampled for at least 30 days before a model is selected. Baseline current handle time, current error rate, current escalation pattern. Document the workflow the AI sits inside. Architecture. Versioned prompts, evaluation suites, shadow-mode rollout. Only what passes evaluation reaches production. ISO/IEC 42001-aligned governance scaffolding. Citations. Every output - extracted field, drafted response, retrieved passage, decision recommendation - links back to the source it came from, the model version that produced it, and the timestamp. The audit trail rebuilds in seconds. ## What can go wrong and how do we prevent it? Each document lands in immutable storage with a content hash, runs through layout-aware OCR and a structured extraction pass that returns field-level confidence and citation pointers, hits the validation rule set (format, cross-field, regulatory), and surfaces only sub-threshold fields for human review. The verified record then writes to the system of record with full lineage and a queryable audit event. The failure modes we engineer against on every banking build: hallucinated content surfaces (mitigated by grounded retrieval and a "no source, no answer" fallback), drift over time (mitigated by quarterly drift reports against the eval set), permission leakage (mitigated by ACL-aware retrieval), and silent regression after a model swap (mitigated by shadow-mode redeploys with eval delta sign-off). ## What gets shipped in a Lighthouse build? Phase one (weeks 1-2) is the readiness sprint: data sampling, baseline measurement, AI Act risk classification, scope sign-off. Phase two (weeks 3-4) is the build and shadow-mode rollout, where the system runs alongside the banking team with output logged but not actioned. Phase three (from week 5) extends to production, additional document categories or channels or knowledge domains, and the recurring drift and accuracy review that keeps the system honest. Pilot engagements at this scope start at EUR 25,000 for a single, well-scoped category. Full production deployments typically land between EUR 60,000 and EUR 150,000 depending on integration complexity, evaluation-set breadth, and the regulatory documentation depth your team requires. Submit a project for a custom estimate. ## How does this compare to off-the-shelf document processing tools? Off-the-shelf platforms (UiPath, Salesforce Einstein, ServiceNow Now Assist, Glean, Microsoft Copilot for the banking variant) work well when your workflow is close to their reference customer. Where they break is when banking regulatory documentation has to be produced for the specific decision the system took, on the specific document or interaction it took it on, against the specific model version that was running at the time. The matrix combination of EU AI Act risk classification, sectoral regulator (EBA, BCBS, FSB, DORA), and your own internal control framework rarely fits a vendor template. Custom builds are how that fit is achieved. ## What we don't build ### We will not auto-process documents below your confidence threshold Field-level confidence below the threshold the banking compliance team agreed routes to human review by default. We do not paper over a 0.7-confidence extraction with a 0.95-confidence summary; the underlying number is the one that surfaces in the audit log. ### We will not train your models on third-party content without licence Reference corpora that are not your own data do not enter your evaluation set or any fine-tune. The provenance of every training sample is recorded; samples without a clean provenance are excluded. ### We will not handle document categories the readiness sprint flags as inconsistent If the 30-day sample shows that a document category arrives in 12 different layouts with 4 vocabularies, we say so and scope it out of the pilot. We come back to it once you have the upstream consistency to support a measurable accuracy target. ## Frequently asked questions ### Is document processing for banking high-risk under the EU AI Act? Article 6(3) preparatory-task carve-out covers most KYC and statement OCR workflows. SR 11-7 still treats the extraction model as a model and requires lifecycle documentation; we ship that scaffolding by default. ### Where is the data processed and stored? By default, processing and storage runs in EU regions on infrastructure under EU jurisdiction. We support specific regional pinning when a regulator or contract requires it. Original documents and interaction logs land in immutable EU object storage with hashes recorded in the audit log. We do not train any model on your data unless you ask us to and the contract permits it. ### How do you handle the regulator audit trail? Every output the system produces - extracted field, drafted response, retrieved passage, decision recommendation - writes a structured event to a queryable, append-only audit log with the model version, prompt, retrieval source, confidence, and the human signer (where one exists) at the moment the action was taken. BCBS 239, SR 11-7, and the relevant sectoral guidance are accommodated by the same log shape. The trail rebuilds any decision in under 10 seconds. ### Can it work with our existing systems? Yes. The delivery layer sits in front of the system of record you already use - case management, claims platform, core banking, AML/KYC platform, ticketing, document repository, contract lifecycle - and writes back through documented APIs or queue-based bridges with idempotent writes. The audit log writes regardless of where the data lands. ### What does this cost? Pilot engagements at this scope start at EUR 25,000 for a single, well-scoped category. Full production deployments typically land between EUR 60,000 and EUR 150,000 depending on integration complexity, evaluation-set breadth, and the regulatory documentation depth your team requires. We quote against your specific scope before any code is written. ### How long does a deployment take? A first pilot reaches production-grade behaviour in 4 weeks. Phase one is the readiness sprint, phase two is the build and shadow-mode rollout, phase three extends to production and additional categories with each new category requiring 1-2 weeks of evaluation work. ## Sources 1.
