The relevance of the topic of the article is due, first, to the growing geopolitical challenges and threats, escalation of international sanctions that undermine the foundations of economic and financial sovereignty of Russia, and, second, to the need to develop science-based solutions, ensuring the ability of the national financial system to maintain stability and independence from external shocks. The purpose of the research is to identify the current problems of Russia’s financial sovereignty and to develop reasoned proposals to ensure it in the context of the international sanction’s matrix. The novelty of the research is that the authors for the first time presented and described a matrix of international sanctions against the financial sovereignty of Russia, as well as developed economically feasible recommendations for its protection in modern conditions. When preparing the theoretical section of the publication, a group of general scientific methods was used: observation, comparison, measurement, analysis and synthesis, method of logical reasoning, critical review of scientific literature and professional publications. In the preparation of the analytical section and development specific recommendations, specific scientific methods (static analysis, graphical method) were used, expert method was used to form scenarios for assessing the future state of the financial sovereignty. The essence of the concept of “financial sovereignty” in the context of the international sanction’s matrix was considered. Available official state and other verified statistics of the number and structure of sanctions against the financial system was collected and processed, as well as points (zones) of application of their destructive influence was identified. As conclusions, expert judgments were formulated on possible tools to protect financial sovereignty and assessed their positive and negative effects, taking into account the volatility of sanctions. The materials of this research can be used as a basis for further justification of promising solutions to protect national financial sovereignty, taking into account foreign economic and military-political trends. The results of the research will be useful to experts in the sphere of state regulation of the national financial system, as well as specialists in the formation of forecasts of socio-economic development of the state.
