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.
“As cyber threats continue to evolve, cooperation across G7 nations is more important than ever. Exercises such as this one strengthen our collective ability to respond to major cyber incidents, improve information sharing among financial authorities, and reinforce the resilience of the global financial system. I thank all participants for their continued commitment to this important work.”
– The Honourable François-Philippe Champagne, Minister of Finance and National Revenue
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.
“In our increasingly global financial system, countries can’t address cyberthreats in isolation. Cross-border coordination exercises allow us to test and align our cyber security preparedness with domestic and international partners. This improves our resilience – both individually and collectively.”
– Tiff Macklem, Governor of the Bank of Canada
