The Swedish Financial Supervisory Authority (Finansinspektionen, FI) has published planning guidance for banks and other financial firms to support preparedness work aimed at ensuring society-critical financial services remain available in crisis and war. The guidance is intended to clarify how firms can organise their planning to secure access to financial services that households, businesses and public functions depend on. The guidance highlights continuity needs for electronic and cash payments, timely salary payments, and continued access to savings, credit and insurance. It reflects Sweden’s civil defence objectives and governance and positions preparedness as both a firm-level responsibility to build capability for severe scenarios and a sector-wide task to develop shared capabilities across the financial system. FI plans to use the guidance as a basis to deepen cooperation with financial firms on identified development needs linked to each firm’s activities and its relevance to Sweden’s total defence.
