**[U.S. Treasury Establishes Quantum Security Working Group to Accelerate Quantum-Resistant Transformation of Financial Systems]** According to a report by Jinse Finance, on August 25, the U.S. Treasury announced the establishment of the "Quantum Security Preparedness Working Group" to lead the financial industry's transition to quantum-resistant cryptographic technologies, aiming to strengthen the security of sensitive data, critical infrastructure, and the digital economy. Treasury Secretary Janet Yellen stated that the U.S. must remain at the forefront of technological security assurance, and this working group will ensure that the financial system remains secure, stable, and competitive in the face of new technological challenges. The working group brings together multiple stakeholders, including government agencies, financial institutions, and technology providers, and focuses on three main tasks: advancing the post-quantum cryptographic migration in the financial sector, enhancing third-party supply chain security preparedness, and assessing risks posed by digital assets and emerging technologies. The Treasury emphasized that once quantum computing matures in the future, it will have the capability to break current encryption systems, posing long-term threats to financial data, payment systems, digital identities, and market infrastructure. Therefore, the early deployment of post-quantum cryptographic technologies is a critical step in safeguarding economic security and the resilience of the financial system.
