Fundamental Problems of Cash Management Development in the Public Sector

The aim of this study is to develop a conceptual model for treasury cash management in the public sector. The model is based on a centralized approach integrating digital management tools and predictive analytics within the framework of a single treasury window paradigm. Research Methodology: A combination of theoretical and empirical methods was used to achieve the research goal. The theoretical part includes analysis and synthesis, induction and deduction, modeling and abstraction. Empirical research is conducted through observation. This combination allowed for a retrospective analysis, identifying current issues and systemic trends in the evolution of treasury cash management in the Russian Federation over the entire period of its institutionalization (2008–2025). Interpretive (generalization and structural) research methods were used to develop the conceptual model. Conclusions: The prerequisites for effective cash management have been substantiated and the problems of managing cash have been systematized. This has revealed the internal structure of the current state of the public financial management system as well as providing a theoretical and methodological platform for further development. A new model for public cash management has been developed, which aims to improve the adaptability, sustainability, and effectiveness of budgetary regulation through the use of digital technology.
