G7 Plans to Simulate AI Cyberattacks on Banks with 2026 Drill to Address Systemic Risks

The G7 is planning simulated AI cyberattack drills on the banking system. The IMF has listed AI-enabled cyber threats as one of three top risks to financial stability — regulators are moving from discussion to live stress-testing.
What exactly is this drill testing?
G7 finance ministers agreed on the plan at the IMF annual meeting in Bangkok: each country's financial authority will design its own scenario and bring in commercial banks for a "tabletop exercise" — a structured war-game where participants walk through an attack step by step and decide how to respond.
The simulated scenarios cover two types: AI-enhanced cyberattacks, and attacks targeting AI infrastructure itself.
This means → the drill tests crisis playbooks, not firewalls. One official compared it to a flight simulator testing a pilot's emergency reactions.
Why act now?
The IMF's Global Financial Stability Report this week delivered a key data point: in 2026, over 70% of cyber vulnerabilities were exploited on or before the day they were disclosed — up roughly 20 percentage points from 2025. In 2018 the figure was about 20%.
In plain terms = defenders used to have a patch window after a flaw was found. AI has compressed that window to near zero, leaving the defense side increasingly reactive.
IMF deputy director Caio Ferreira noted that financial markets rely heavily on a handful of third-party service providers. If one of these concentrated nodes is breached, the loss of confidence alone can trigger a systemic event — even without actual financial losses.
How severe does the IMF consider this?
The IMF classified AI-enabled cybercrime as one of the three main threats to financial stability, stating that "AI models are becoming powerful enablers of cyberattacks and may evolve into a source of systemic risk."
The report warned: "A severe cyber incident could undermine market confidence and disrupt critical financial market infrastructure and operations."
This reflects a decisive shift: regulators no longer treat AI cyber threats as a technology problem — they now sit alongside credit risk and liquidity risk as systemic threats.
What are officials and bankers saying behind closed doors?
Dutch Finance Minister Eelco Heinen was the most blunt: "We are all looking at the same black box… If a few countries master this technology while the entire world could become a victim, international cooperation is essential."
A senior risk manager at a Middle Eastern bank said concern about AI's "unknown unknowns" is mounting — "No banker wants to hint that a crisis is coming, but insiders are paying close attention to AI's unknown risks."
South Korea's president said there are signs AI models have been used to attack banks; the UK's FCA warned that frontier AI models find vulnerabilities faster than financial firms can patch them; Bank of England Governor Andrew Bailey called for more testing of AI models and higher safety standards.
After the drill — what comes next?
The G7 exercise has no confirmed timeline yet, but the direction is clear: use a stress test to verify whether national financial systems' emergency coordination mechanisms actually hold up.
This means → the results will expose gaps in each country's crisis playbook, likely driving upgrades to cross-border emergency protocols and AI security standards.
In plain terms = this is not a one-off exercise but a starting point — if the playbook fails the test, the rules get rewritten.
