Finance Regulators to Address AI Risks After MPs Say They Are ‘Not Doing Enough’

Why It Matters

Proactive AI regulation protects financial stability and prevents systemic shocks, reinforcing the UK’s reputation as a safe investment hub. Designating critical IT providers under the CTPR adds a legal safety net against outages that could disrupt markets.

Key Takeaways

• Bank of England to test AI agents for market herding risk
• FCA shifts from rule‑based guidance to AI‑focused best practices
• MPs demand IT suppliers be added to Critical Third Parties Regime
• Anthropic's Mythos model reveals decades‑old vulnerabilities in finance

Pulse Analysis

The Treasury Committee’s January report sparked a rare public rebuke of the UK’s financial watchdogs, highlighting a perceived "wait‑and‑see" stance toward artificial intelligence. Lawmakers argue that unchecked AI could amplify existing market fragilities, especially as banks integrate increasingly sophisticated models. By publicly acknowledging the criticism, the Bank of England and FCA signal a shift toward transparency and accountability, laying groundwork for tighter supervisory frameworks.

In response, the Bank of England disclosed plans to simulate AI‑driven trading agents, focusing on correlated behaviour that can trigger herding and flash crashes. Simultaneously, the FCA abandoned its usual rule‑by‑rule playbook, opting instead to publish sector‑specific best‑practice examples that align AI deployments with existing regulatory standards. These moves aim to close the guidance gap, giving firms a clearer roadmap while preserving innovation.

Beyond immediate oversight, the debate underscores broader systemic concerns. MPs are urging the Treasury to fast‑track the inclusion of major IT vendors in the Critical Third Parties Regime, a measure designed to mitigate cascading failures from supplier outages. The recent uncovering of legacy vulnerabilities by Anthropic’s Mythos model adds urgency, as national security and financial stability become intertwined. Continued dialogue between regulators, banks, and tech providers will be essential to balance AI’s transformative potential with the need for robust safeguards.
