G7 2026 CROSS BORDER COORDINATION EXERCISE (CBCE)

The G7 Cyber Expert Group (CEG) successfully concluded its 2026 Cross-border-coordination exercise (CBCE) on May 18, 2026. This exercise demonstrates the Group’s ongoing commitment to strengthening cyber resilience across the G7 financial sector. A long-term exercise strategy has now been adopted to increase the frequency and consistency of these simulations, thereby enhancing preparedness across all jurisdictions.Building on the success of the 2024 CBCE exercise, which aimed to strengthen the G7 financial authorities’ capacity to coordinate and communicate effectively in response to a major cross-border cyber incident affecting the financial sector, this year’s sessions tested key improvements identified through previous simulations and workshops focused on incident response, recovery, and crisis communication, further advancing collective preparedness. To enhance coordination among G7 financial authorities, the exercise simulated a large-scale cyber-attack across all G7 jurisdictions.
