Sheldon Mills, executive director at the FCA, recently highlighted that the increasing reliance on a handful of technology providers poses systemic risks to the broader financial sector. While financial advice remains a strictly regulated activity, adaptive AI chatbots are blurring the lines between generic information and personalized, actionable recommendations. Mills recommended that the regulator assess its current perimeter within the next six months to determine if existing rules can adequately capture the impact of these evolving models.

Beyond individual advice, the concentration of AI infrastructure creates a critical vulnerability. As firms move AI tools from back-office functions into customer-facing roles like investment guidance, they become tethered to a few dominant providers. This shared reliance risks correlated behavior and common points of failure across the market. Jonathan Herbst, global head of financial services at Norton Rose Fulbright, noted that while this review does not signal an immediate crackdown, it forces a necessary debate on whether financial regulations can keep pace with rapid technological adoption. Bank of England deputy governor Sarah Breeden echoed these concerns, stating that current frameworks remain ill-equipped to manage autonomous agents that operate without consistent human intervention.
