BoE’s Bailey: Frontier AI Raises Cyber Attack Risk, Needs Broader Testing

Bailey's framing matters because it links two risks that are usually discussed separately: the security exposure from frontier models and the valuation risk building in AI-linked assets. Coming from a central bank governor rather than a tech regulator, it signals that AI is now being treated as a financial stability issue, not just an innovation one — relevant to banks, insurers and anyone holding AI-adjacent exposure. The tension in his remarks is notable: early signs of a positive supply shock alongside a warning about overvaluation. Whether supervisors move from commentary to concrete testing requirements is the open question.
