G7: Cyber Expert Group issued a statement on advancing a coordinated roadmap for transition to post-quantum cryptography in the financial sector

On 13 January 2026, the G7 Cyber Expert Group (CEG) published a statement titled Statement on advancing a coordinated roadmap for the transition to post-quantum cryptography in the financial sector. The document provides a framework for financial entities and authorities to transition to quantum-resistant cryptography and cryptographic agility. The stated aim of the roadmap is to manage cryptographic risks introduced by quantum computing to maintain the resilience of financial systems. It outlines six migration phases, including awareness and preparation, discovery and inventory, risk assessment and planning, migration execution, migration testing, and validation and monitoring. The statement identifies 2035 as a target date for sector-wide migration, with systems identified as critical potentially transitioning between 2030 and 2032. The CEG committed to monitoring migration progress and coordinating with international standard-setting bodies.
