- The FCA published the Mills Review on July 6, 2026, examining AI's impact on retail financial services.
- The review identifies four key AI-driven shifts impacting operations, consumer journeys, competition, and fraud risks.

The UK's Financial Conduct Authority (FCA) released the Mills Review on July 6, 2026, a comprehensive study on how artificial intelligence will reshape retail financial services.
Authored by FCA Executive Director Sheldon Mills, the report highlights four critical AI-driven changes: transformation of firm operations, evolution of consumer journeys, reshaping of competition and market power, and an increase in fraud and cyber risks. As Mills stated, "Artificial intelligence will transform financial services by 2030. It creates significant opportunities for consumers, firms and the wider economy." He also warned it is "an arms race," underscoring urgency.
A key data point from the review is that 20% of UK consumers—around 11 million adults—are likely to use AI tools capable of autonomous actions within predefined goals. This signals widespread consumer interaction with AI-guided financial decisions.
To address these developments, the FCA proposes seven main recommendations for tightening AI oversight. These include adapting and securing the regulatory framework and enhancing coordination across systems to manage AI risks effectively. The FCA also plans to publish an AI good and poor practice guide later in 2026, aiming to give clear directions to firms leveraging AI.
The Mills Review is a proactive step for the FCA, targeting balanced innovation and consumer protection. Legal and compliance teams within financial firms will need to monitor these regulatory shifts closely, as the outcomes may influence broader legal technology governance beyond finance.
By the numbers:
- 20% of UK consumers — likely to use autonomous AI in financial services
- 11 million adults — estimated UK population engaging with AI tools
- Seven recommendations — proposed by FCA to enhance AI oversight in financial sector
What's next: The FCA plans to release an AI good and poor practice guide later in 2026 to clarify regulatory expectations.
