Anthropic to brief financial regulators on Mythos AI risk

AI start-up Anthropic is set to brief the Financial Stability Board (FSB) on cyber vulnerabilities in the global financial system identified by its latest model, Mythos, the Financial Times reported on Monday, citing people familiar with the plan.

The Claude chatbot maker will discuss the capabilities of its new Mythos Preview AI model with leading finance ministries and central banks from the FSB, following a request by Bank of England Governor Andrew Bailey, the FT said.

South Africa is a member of the FSB, and is represented on the body by Reserve Bank governor Lesetjsa Kganyago and the director-general of the national treasury, Duncan Pieterse. Bailey chairs the global risk watchdog, which is responsible for coordinating financial rules for G20 economies.

Mythos, announced last month but not yet released, is an AI model that can detect decades-old vulnerabilities in web browsers, infrastructure and software, according to Anthropic.

Cybersecurity experts have warned the system could supercharge more sophisticated cyberattacks, posing a risk to the banking industry reliant on legacy technology systems.

In April, BoE governor Bailey warned that Mythos could pose major security risks to the cyber world.

“It would be reasonable to think that the events in the Gulf are the most recent challenge to us in this world, until, I think it was last Friday, you wake up to find that Anthropic may have found a way to crack the whole cyber-risk world open,” Bailey said at an event at Columbia University in New York last month.

“The issue is: to what extent is this new version of the product going to be able to, in a sense, identify vulnerabilities in other systems which can be exploited for cyberattack purposes,” Bailey said.  — Ananya Palyekar, (c) 2026 Reuters, with additional reporting (c) 2026 NewsCentral Media
