Research Question

How does uncoordinated growth of department-level software agents change systemic risk and reporting integrity in banks, and which governance architecture can maintain consistency across agents, traceable version and decision history, and operational resilience as bottlenecks shift from data entry to compliance decision queues?

Findings

Executive Summary

Banks need one central governance core for inventory, policy, traceable version history, and resilience evidence, while domain teams can still run agents locally inside shared rules. Uncoordinated local agent growth raises systemic risk mainly by multiplying cross-division inconsistencies, shared-data dependencies, third-party concentration, and unreconciled overrides rather than by creating a wholly new prudential risk class. As automation removes manual data-entry work, a primary operational bottleneck often moves into validation, exception handling, incident triage, and compliance decision queues, so those queues need explicit resilience, staffing, and fallback controls. Other bottlenecks, including data-quality failures, third-party outages, and control misconfiguration, remain material, so queue governance should be treated as a central recurring dependency rather than as the only post-automation risk.

Assumptions

Assumption: Consequential software agents should be governed with bank model-risk discipline even when a local tool owner would classify them as workflow systems rather than as formal models. Justification: the supervisory concern is adverse decisions from incorrect or misused outputs, which remains relevant here.
Assumption: DORA is used here as a strong banking-resilience benchmark even where a specific bank or division is not directly supervised under European Union law. Justification: the mapped control families are still useful as design tests for resilience and auditability.
Assumption: Banks will continue to retain human approval for material exceptions, incidents, and policy changes. Justification: the reviewed resilience and security sources assume ongoing human responsibility for the most consequential decisions.

Analysis

The evidence was weighted toward prudential regulators and standards bodies because the research question asks for auditable governance architecture, not for comparative vendor capability marketing. The 2011 guidance and the 2026 revised guidance were read together, because the older document supplies the operational mechanics of inventory, effective challenge, and validation while the newer notice confirms that those mechanics still need to be applied proportionately. DORA, ISO/IEC 42001, and National Cyber Security Centre guidance were treated as complementary control families rather than competing regimes: DORA concentrates on resilience operations, ISO/IEC 42001 on management-system discipline, and National Cyber Security Centre guidance on secure lifecycle practice. The architecture recommendation therefore prioritises central control services and explicit queue governance over per-division optimisation, because the systemic failure mode emerges from dependencies and unreconciled states, not from a lack of local automation. A fully centralized model would simplify evidence collection but would also concentrate operational load and slow domain change, while a standards-only decentralized model would preserve local speed but fragment inventory and contradiction evidence, which is why the hybrid model is preferred. Other post-automation bottlenecks, including data-quality failures, identity misconfiguration, and third-party outages, remain plausible, but review and exception queues are the most predictable human-governed chokepoint in the cited evidence base.

Risks, Gaps, and Uncertainties

Public banking sources define the retained human control tasks clearly, but they do not publish enough queue telemetry to turn bottleneck migration into a quantified universal rule.
The DORA mapping in this item relies on official regulator summaries and chapter structure rather than direct article-by-article parsing, so narrower legal nuances could adjust implementation detail without changing the overall control architecture.
The accessible ISO/IEC 42001 evidence is an official standard summary rather than the full clause text, so this item uses the standard for management-system direction and not for clause-by-clause certification interpretation.

Open Questions

Which bank metrics are most decision-useful for queue governance: backlog age, decision latency, exception recirculation rate, or override aging?
How should banks distinguish agents that deserve full model-risk treatment from workflow agents that can stay under lighter controls without creating blind spots?
Which contradiction patterns should trigger automatic rollback, and which should route into supervised human reconciliation?
