UK banks remain blocked from Mythos AI access as cyber risk concerns persist
British banks are still unable to access Anthropic's Mythos artificial intelligence model for cyber threat testing, six weeks after the issue first raised concern at the Bank of England. The delay highlights regulatory and cross-border tensions around advanced AI tools as officials push for broader safeguards against systemic hacking risks.
Highlights
- Bank of England Governor Andrew Bailey confirms UK banks remain unable to access Anthropic's Mythos AI model for cyber threat testing due to U.S. political delays.
- Bailey emphasizes that cyber threats from advanced AI require coordinated international oversight, citing the heavy interconnection of global banks.
- President Donald Trump postponed signing an executive order to establish a voluntary AI framework for developers, further delaying regulatory clarity on model access.
Bank of England presses for model access
As reported by Reuters, Bank of England Governor Andrew Bailey says British lenders still cannot use Anthropic's Mythos model on a trial basis to assess their systems against cyber threats, despite the company's apparent willingness to share access.Speaking to Bloomberg TV on the sidelines of a central banking conference in Reykjavik, Bailey says the process appears to be held up politically within the U.S. administration. He says the differing treatment between companies is hard to explain, but adds that access is important given the scale of the risks involved.
Anthropic has already clashed with the U.S. administration over guardrails governing how the military could use its AI tools. Last month, Bailey warned that Anthropic may have found a way to transform the cyber risk landscape, though some cybersecurity experts have since told Reuters that fears of unrestricted hacking through the model are overstated.
Global oversight concerns for financial stability
Bailey, who also chairs the Financial Stability Board, says hacking threats linked to advanced AI require an international response rather than isolated national measures.He says cyber spillovers are too large for any one country to manage alone, especially because banks remain heavily interconnected. His comments come after President Donald Trump last week postponed signing a broader executive order on AI that was expected to set out a voluntary framework for developers to engage with the U.S. government before releasing advanced models to the public.
Andrew Bailey previously cautioned that even a potential 60-day ceasefire in the Middle East would not materially reduce the economic risks facing the UK. He said policymakers would need much stronger confidence that any energy-price drop would not feed into underlying inflation before considering interest rate cuts.
