Britain’s financial watchdog floats AI regulation, and crypto firms should pay attention

A senior official at the UK’s Financial Conduct Authority has suggested that Britain should consider regulating general-purpose AI models, the kind that power ChatGPT, Claude, and Gemini. The recommendation, made on July 6, landed in the middle of an already heated debate about whether the UK’s light-touch approach to AI governance is actually working.

What the FCA is actually saying

The FCA isn’t proposing to write new AI-specific rules. The regulator has consistently maintained it will apply existing frameworks, specifically the Consumer Duty and the Senior Managers and Certification Regime, to AI use cases in financial services.

The suggestion to consider regulating the underlying AI models themselves, not just how financial firms use them, represents a subtle but meaningful shift. It’s the difference between regulating the driver and regulating the engine manufacturer.

This recommendation comes out of the broader Mills Review, which the FCA launched on January 27, 2026, specifically to investigate how AI is reshaping retail financial services.

Meanwhile, the UK Treasury Committee has been less patient. In its January 2026 report, the Committee criticized the FCA for lacking explicit guidance on AI usage in financial services. Lawmakers urged the regulator to clarify consumer protection and accountability rules by the end of 2026.

The UK’s innovation-first gamble

Britain has deliberately positioned itself as the anti-EU when it comes to AI governance. While Brussels rolled out the comprehensive EU AI Act with tiered risk classifications and strict compliance requirements, London has opted for a sector-specific, pro-innovation approach.

The FCA AI Lab, launched back in October 2024, embodies this philosophy. It’s designed to let firms experiment with AI technology in a supervised sandbox without triggering new legislative requirements. The more recent AI Live Testing pilot follows the same playbook.

Why crypto firms can’t afford to ignore this

If the UK moves toward regulating general-purpose AI models, any firm using ChatGPT, Claude, or Gemini APIs for customer-facing financial advice or decision support could face new compliance obligations.

Second, the accountability question gets thorny. Under the Senior Managers and Certification Regime, specific individuals within regulated firms bear personal responsibility for outcomes. When an AI model hallucinates a piece of financial advice that causes consumer harm, who’s on the hook? The firm that deployed it, the executive who approved its use, or the company that built the model? The FCA’s existing framework points to the first two. Regulating the models themselves could extend that chain.

The Treasury Committee’s demand for clarity by the end of 2026 sets a rough timeline. Crypto firms operating in or eyeing the UK market have roughly six months to assess how their AI integrations might be affected.
