A string of hacking incidents in South Korea’s financial sector has led to confirmed personal data leaks at savings banks and mutual finance groups, prompting authorities to step up inspections and security requirements. Banks are moving to raise cybersecurity spending and expand fraud prevention systems using AI. Market volatility and a steep stock selloff also drew a policy response. Political debate intensified over postponing digital asset taxation and regulating exchange shareholders.

South Korea\'s National Union of Financial Industry Workers called on the government to immediately withdraw its plan to relocate the Financial Services Commission to Sejong. The union said moving the commission could weaken cooperation among financial policymakers, supervisors and financial firms and undermine national competitiveness. It said swift decision-making and on-the-ground response were crucial during past crises. The union also demanded a halt to discussions on relocating major financial institutions outside Seoul.
