The Bank for International Settlements' Financial Stability Institute (FSI) published an assessment of supervisory information systems, finding uneven progress toward integration. Of 43 surveyed financial authorities, eight had fully integrated systems for data collection, risk assessment, regulatory compliance monitoring and workflow management, while 15 had achieved partial integration. Fragmentation was more common among authorities in emerging market and developing economies. Integrated systems provide supervisors with more timely and consistent information, streamline workflows and create the data and interoperability foundations needed to deploy artificial intelligence at scale, including agentic AI. However, authorities face legacy infrastructure, poor data quality, interoperability and cyber risks, as well as resistance to organizational change and vendor-related lock-in and concentration risks. The paper identifies leadership support, cross-functional collaboration, strong data governance, modular and open architecture, pilot projects and iterative implementation as key practices, emphasizing that success should ultimately be measured by improved supervisory effectiveness rather than technology deployment alone.
