G7 Cyber Expert Group Launches 2026 Cross-Border Coordination Exercise for Enhanced Cybersecurity Collaboration

The G7 Cyber Expert Group (CEG) has successfully wrapped up its 2026 Cross-border Coordination Exercise (CBCE) on 18 May 2026. This exercise underscores the Group’s enduring commitment to bolstering cyber resilience within the G7 financial sector. A long-term strategy for conducting these exercises has now been put in place to enhance the frequency and consistency of such simulations, thereby improving preparedness across all jurisdictions.

Advancements from Previous Exercises

Building on the achievements of the 2024 CBCE exercise, which was designed to bolster the capacity of G7 financial authorities to coordinate and communicate effectively in the event of a significant cross-border cyber incident impacting the financial sector, this year’s sessions tested key enhancements identified from prior simulations and workshops. These focused on incident response, recovery, and crisis communication, further advancing collective preparedness. The exercise simulated a large-scale cyber-attack across all G7 jurisdictions, facilitating improved coordination among financial authorities. This scenario engaged ministries of finance, central banks, banking supervisors, and market authorities, fostering a unified response to potential threats.

Through these exercises, the G7 Cyber Expert Group aims to strengthen the financial sector’s ability to withstand cyber threats and mitigate potential disruptions across member jurisdictions. This initiative allows financial authorities to better align and integrate the various operational and strategic components necessary for an effective response to cyber incidents.

Prioritising Preparedness and Information Sharing

In a world that is becoming increasingly interconnected, cross-border coordination, preparedness for incident response, and timely information sharing continue to be top priorities for the G7. The G7 Cyber Expert Group remains committed to collaborating and addressing potential cyber threats to ensure the stability and integrity of the global financial system.

Understanding the G7 Cyber Expert Group

The G7 Cyber Expert Group is tasked with coordinating cybersecurity policy and strategy across G7 jurisdictions.
