G7 Cyber Expert Group 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. The scenario brought together ministries of finance, central banks, bank supervisors, and market authorities, fostering a unified response.

Through these exercises, the G7 Cyber Expert Group seeks to reinforce the financial sector’s capacity to withstand cyber threats and reduce potential disruptions across G7 jurisdictions.

This initiative enables financial authorities to further align and integrate the various operational and strategic components required for an effective response to cyber incidents.

In an increasingly interconnected world, cross-border coordination, incident response preparedness, and timely information sharing remain key G7 priorities. The G7 Cyber Expert Group continues to work and collaborate to address potential cyber threats to safeguard the stability and integrity of the global financial system.
