BoE Regulator Flags AI Models Disruption Risk

PRA chief Sam Woods warned AI models like Anthropic’s Mythos and ChatGPT 5.5 Instant could cause major disruption to financial services.
Woods said the models can pinpoint system vulnerabilities, making rapid patching essential as it drives most outages in the sector.
He urged banks to boost basic cyber hygiene and adopt AI‑driven defenses, emphasizing faster threat response across their operations.
Anthropic launched Mythos to a set of businesses in April, while a BoE cyber group said sector was prepared for such challenges.
