Key facts

  • Same day: a Bank of England deputy governor said the BoE is working with banks on deep cyber-recovery options, as banks can no longer assume their defences are immune to AI-enabled attacks
  • Earlier: G7 finance leaders agreed in May 2026 (Paris) to work on concrete responses to advanced-AI cyberattacks; the G7 Cyber Expert Group’s 2026 cross-border exercise (not AI-specific) ended May 18

What happened

Meeting on the sidelines of the IMF and World Bank annual meetings in Bangkok, G7 finance ministers and central bank governors agreed to run tabletop exercises on AI-driven cyberattacks against the financial system. Japanese Finance Minister Satsuki Katayama announced it on Oct 15. A Japanese finance ministry official said the simulations will test how authorities respond and will be used to revise incident manuals, and could include private banks. The step followed the IMF’s warning in its October Global Financial Stability Report and comes as the Bank of England and other regulators press banks on cyber recovery.

Why it matters

Finance ministries and central banks are now treating AI-enabled cyberattacks as a systemic risk that needs coordinated drills, not only bank-level supervision. In the same week US regulators questioned banks about agentic AI and the FSB published sound practices. The plan has no published timeline or scenarios yet.
