# G7 finance leaders plan AI cyberattack drills

Full title: G7 finance ministers and central bankers agree to run tabletop exercises against AI-driven cyberattacks

On Oct 15, 2026, after a meeting on the sidelines of the IMF annual meetings in Bangkok, Japanese Finance Minister Satsuki Katayama said G7 finance ministers and central bank governors agreed to hold tabletop exercises simulating AI-driven cyberattacks on the financial system. A Japanese official said the results will be used to test existing protocols and revise manuals, and that private financial institutions may take part. It followed the IMF's warning that week that an AI-enabled cyberattack on a critical financial service could undermine confidence.

## Key facts
- Announced by Japan's Finance Minister Satsuki Katayama to reporters on Thursday, Oct 15, 2026 (Reuters, datelined Bangkok, Oct 16)
- Format: simulations designed by G7 finance authorities to test responses to AI-driven cyberattacks; results to test protocols and revise manuals (Japanese finance ministry official)
- Private financial institutions could join, depending on the simulation
- Trigger: the IMF's October Global Financial Stability Report warning about an AI-enabled cyberattack on a critical service of a financial institution
- 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
- No dates, schedule or scenarios for the AI exercises were reported

## 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.
