The FCA's Mills Review: What AI Actually Means for Your Money

On 6 July 2026, the FCA published the Mills Review — the first review of its kind by any global regulator into how artificial intelligence will reshape retail financial services by 2030. Led by FCA executive director Sheldon Mills, it's a landmark attempt to get ahead of a shift that's already underway in banking apps, investment platforms, and insurance.

What the review found

The FCA's own findings identify four AI-driven shifts already reshaping the market: how firms operate internally, how consumers make financial decisions, how competition and market power shift between firms, and — more worryingly — how fraud and cyber risk are amplified by the same tools.

Research commissioned for the review found that 11 million UK adults — roughly a fifth of the population — are likely to use AI tools that act autonomously within pre-set goals, such as an agent that automatically moves savings to the best rate or manages a budget. But the same research found consumers are uneasy about trust and control once AI starts acting on their behalf.

What the FCA wants to do about it

Rather than writing brand-new AI-specific rules, the review recommends the FCA stick with its existing principles-based, outcomes-focused approach, adapted through seven priority recommendations, including scaling up its AI Lab, building an "AI-enabled agentic supervisory model," and securing the regulatory perimeter so agentic finance tools don't operate outside its reach. Notably, the FCA is also asking government to consider whether general-purpose AI models themselves should fall under financial regulation.

Why this affects ordinary savers and investors

If you already use a robo-adviser, a budgeting app that categorises spending automatically, or a chatbot for customer service with your bank, you're using a small piece of what this review is about. As "agentic" tools — ones that don't just recommend but act — become more common, questions of liability (who's responsible if an AI agent makes a bad trade or misses a bill) become live regulatory issues rather than hypotheticals.

Other regulators are moving on similar timelines: the EU's AI Act already imposes risk-based obligations on financial AI systems, and US regulators including the SEC have flagged similar concerns about "AI washing" and algorithmic trading risk, though without a single unifying review of this scope.

What to watch for

• Whether your bank or platform introduces "agentic" features that act on your behalf without a confirmation step each time
• Terms and conditions changes describing AI decision-making in your existing apps
• The government's response to the FCA's call for wider AI oversight powers, expected as this review is digested by Parliament and Treasury
