The relevance. The article substantiates the concept of financial sovereignty as a fundamental characteristic of the state, reflecting its ability to independently formulate and control key parameters of the financial and economic system in the context of globalisation. The objective of the study is to develop the theoretical and methodological foundations of ensuring financial sovereignty through the development of a comprehensive system of assessment indicators. Methodology is based on the synthesis of fiscal, monetary, economic, institutional approaches and the direction of financial security, an original system of indicators is proposed, grouped into seven key blocks. The scientific novelty of the research lies in the formation of a “diagnostic panel” for a comprehensive assessment of financial sovereignty, allowing for the transition from reactive to preventive risk management. The practical significance of the work is determined by the possibility of applying the developed system of indicators by regulatory authorities to monitor threats to national economic security.
