The Group of Seven (G7) economies have formalized plans to conduct simulated artificial intelligence (AI) attacks on banks, a decision announced by Japanese Finance Minister Satsuki Katayama on October 16, 2026, during the International Monetary Fund's (IMF) annual meetings in Bangkok, Thailand [1][2][4]. The initiative specifically targets the financial system's ability to withstand AI-powered cyberthreats, a growing concern among international financial bodies [2][6].

This move is significant because AI-driven cybercrime poses a substantial risk of destabilizing financial systems and eroding public confidence in major institutions [7][9][10]. The planned exercises aim to proactively address these advanced, machine-speed threats, affecting how global financial authorities prepare for future cyber challenges.

## What the records show

The G7's initiative involves "tabletop drills" that will use simulated incidents and hypothetical scenarios, deliberately avoiding live-environment penetration testing to prevent disruptions to active market infrastructure [11][12]. The primary objective is to evaluate the effectiveness of G7 financial authorities and institutions in detecting, containing, and recovering from AI-driven cyberattacks [13]. These drills will specifically focus on attacks powered by AI [14].

Key areas for assessment include existing safeguards, the speed of detection, the efficacy of containment measures, and the ability to restore systems after a breach [15]. The findings from these simulations are intended to update existing crisis response plans, revise operational manuals, and identify any gaps in cross-border cybersecurity protocols [16]. Participants will primarily include G7 finance ministries and central banks [17]. Depending on the specific scenario, private banks and major financial institutions may also be involved to test the wider financial system's recovery capabilities [18]. This broad participation seeks to assess how well various entities can coordinate their responses to a significant cyber event [19]. This initiative builds upon previous G7 efforts to enhance cyber resilience, marking a significant evolution with its explicit focus on AI as an attacker's weapon [20][21].

## The timeline

Japanese Finance Minister Satsuki Katayama announced the decision on October 16, 2026 [1][4]. The agreement was reached during the IMF annual meetings, which took place in Bangkok, Thailand, from October 12 to October 18, 2026 [3][24][25]. Just two days prior to the G7 announcement, on October 14, 2026, Bank of England Governor Andrew Bailey and IMF Managing Director Kristalina Georgieva issued warnings about the escalating threat of AI-driven cybercrime at meetings involving the IMF and World Bank in Bangkok [8][9]. Earlier in the week, the IMF had also warned that confidence could be undermined by an "AI-enabled cyber attack on a critical service of a financial institution" [10].

## What changed and for whom

This initiative represents a significant evolution in the G7's approach to cyber defense by explicitly focusing on AI as an attacker's weapon [21]. Previously, the G7 Cyber Expert Group (CEG) had advised G7 Finance Ministers and Central Bank Governors on cybersecurity policy [20]. The new plan means that G7 financial authorities and potentially private banks will now be engaged in specific exercises designed to prepare for and respond to sophisticated AI-powered cyber threats [13][17][18]. The goal is to fortify the resilience of the financial system against a new class of threats, impacting regulatory bodies and financial institutions across G7 member nations [2][16].

## What the subject has said publicly

Japanese Finance Minister Satsuki Katayama confirmed the decision to reporters on October 16, 2026 [4]. She has served as Japan's Minister of Finance since October 2025 and is the first woman to hold this position in Japan [4][5]. The plan, initially discussed by G7 finance deputies, received ministerial-level approval [4]. While not directly quoted on the specifics of the plan beyond the announcement, the context of the IMF meetings indicates a shared concern among financial leaders regarding AI-driven cybercrime [8][9].
