The UK’s top financial watchdog just admitted it’s losing ground to the machines. FCA Chief Executive Nikhil Rathi used a speech on June 24 to warn that regulators are locked in an “arms race” with artificial intelligence in financial services, one where the technology side has a serious head start.
The core problem is straightforward: AI agents can adapt and evolve within weeks or months. Regulatory frameworks, built for a world of quarterly reports and annual reviews, operate on a fundamentally different clock.
The scale of the problem
Rathi cited studies showing over 80% of financial services firms are already incorporating AI into their operations. Rathi delivered his warning at a techUK event focused on generative AI. The speech landed months after the House of Commons Treasury Committee published a report in January 2026 that essentially told regulators their “wait-and-see” approach was a dangerous gamble.
Bank of England Deputy Governor Sarah Breeden has separately cautioned about autonomous AI agents operating in trading and payment systems. Her specific concern: these agents could trigger a “market meltdown” if left unchecked.
