TL;DR: RBI’s June 2026 model risk guidance requires banks and other supervised firms to govern every model that affects a business decision, with live inventory, independent validation, and continuous monitoring now central to compliance, according to AccuKnox. Shadow models, third-party model updates, and multi-turn prompt attacks turn model governance into a runtime security problem rather than a paperwork exercise.
Editorial analysis by NHI Mgmt Group, based on content published by AccuKnox: “RBI’s AI Model Risk Management – AI Security Compliance Mandate for Banks”.
Key questions
Q: What breaks when a bank cannot see all of its live AI models?
A: Without a live inventory, the bank cannot reliably validate, monitor, or retire the models that actually influence decisions.
Q: Why do third-party models still create regulatory risk?
A: Because accountability does not transfer with the vendor certificate.
Q: How should security teams reduce prompt injection risk in AI agents?
A: Security teams should reduce prompt injection risk by constraining what enters the context window, limiting tool permissions, and separating untrusted retrieval content from privileged instructions.
Practitioner guidance
- Implement a live AI model inventory Map every in-house and third-party model, notebook, inference service, dataset, and pipeline to a continuously refreshed inventory before allowing production use.
- Require independent red-teaming for every material model change Retest models before launch, after provider updates, and after any material prompt, policy, or deployment change that could alter behaviour.
- Apply stateful runtime controls to customer-facing GenAI Inspect the full conversation, not just a single prompt, and enforce topic, token, and response restrictions at the session boundary.
Bottom line: RBI’s model risk guidance turns AI governance into an operational discipline because every model that shapes a business decision must now be discoverable, validated, and monitored in motion.

Live AI governance is now a control-plane issue, not a policy supplement. The RBI guidance reflects a broader shift in regulated AI: model approval is no longer enough if the deployed system can change through shadow deployment, provider updates, or hidden runtime pathways. This is where identity and governance intersect, because the organisation must know which system is acting, on whose authority, and under what controls. Practitioners should treat model inventory, validation, and monitoring as part of the operational control plane.
A few things that frame the scale:
- Only 23% of IT leaders were very confident in their organisation's ability to manage security and governance for GenAI deployments, according to a 2025 Gartner survey of 360 IT leaders.
A question worth separating out:
Q: What is the difference between vendor certification and independent validation for AI models?
A: Vendor certification is a provider’s assurance about its own testing, while independent validation is evidence that the model behaves safely in your environment and for your use case. They are not interchangeable. For regulated AI, the deploying institution must prove ongoing suitability, especially after updates, integrations, or changes in business context.
