The Bank of Italy hosted a meeting of the G7 Cyber Expert Group in Palermo from 9 to 11 June, bringing together G7 and European Union financial authorities to discuss cybersecurity and operational resilience in the financial sector. The meeting focused on lessons from a recent exercise testing coordination among G7 authorities in response to a global cyberattack scenario, alongside the cybersecurity implications of wider use of emerging technologies, particularly artificial intelligence and quantum computing. The G7 Cyber Expert Group, established in 2015, is a standing working group that supports international cooperation through information sharing, joint threat analysis and common approaches to risk mitigation. In remarks during the meeting, Stefano Siviero, head of the Directorate General for Payments and Market Infrastructures, linked the discussion to a more complex geopolitical environment and a constantly evolving threat landscape, arguing that financial system security increasingly depends on strengthening not only individual firms but also the wider global financial ecosystem through coordinated management of operational interdependencies, emerging risks and new vulnerabilities.
