The G7 Cyber Expert Group publishes the roadmap for the transition of the financial sector to post-quantum cryptography

The G7 Cyber Expert Group (CEG) has published a roadmap to support the orderly transition of the financial sector towards post-quantum cryptographic solutions, with a view to ensuring the resilience of financial systems against the risks posed by the development of future quantum computers. The roadmap represents an important step in strengthening international cooperation on emerging cyber risks and provides a shared reference framework for authorities, financial institutions, and critical service providers across G7 jurisdictions.

The initiative has its roots in the priorities set under the Italian G7 Presidency and builds on the outcomes of a G7 workshop on quantum computing and financial stability hosted by Banca d'Italia in September 2024. The workshop marked a key step in advancing a common understanding of the opportunities and risks associated with quantum technologies and in laying the foundations for the development of concrete and coordinated actions within the G7 CEG.

The roadmap - developed by a dedicated task force established under the Canadian G7 Presidency in 2025 and composed of experts from G7 authorities and industry - sets out a structured approach to the migration of cryptographic systems. It identifies the main phases of the transition and the activities required to ensure operational continuity, interoperability, and the overall resilience of the financial system. In particular, it recommends prioritizing the migration of critical systems and assets within the 2030-2032 timeframe, while completing the transition of non-critical systems by around 2035.

Key elements of the roadmap include international coordination, alignment with evolving standards, and close cooperation between the private sector and other relevant stakeholders. The roadmap confirms the G7 Cyber Expert Group's commitment to supporting a timely and secure transition to quantum-resistant cryptography, strengthening the long-term security and resilience of the global financial system.
