The FCA's stance has crystallized through recent initiatives: an AI Lab launched in October 2024, AI Update publications in 2024 and 2025, and a Mills Review begun in January 2026 examining AI's impact on retail services and accountability frameworks. The Mills Review may signal whether the FCA will tighten rules for autonomous AI systems under the Senior Managers regime. The agency is simultaneously deploying AI in its own supervision, using the technology to analyze enforcement data, detect financial crime, and model fraud patterns. No AI-specific legislation is planned, distinguishing the UK approach from the EU AI Act's risk-based prescriptions.
Firms should expect intensifying supervisory scrutiny as AI capabilities advance and the FCA's enforcement tools grow more sophisticated. The Mills Review outcome will clarify whether current accountability rules adequately address autonomous systems. Attorneys advising financial services clients should ensure governance frameworks explicitly map AI risks to existing regulatory obligations under Consumer Duty and SM&CR, and document evidence-based decision-making around AI deployment—the FCA's stated focus for supervision.
