The subject of the study is a set of criteria, measures and indicators for assessing the financial security of banks and methodological approaches to its evaluation. The purpose of this article is to systematize theoretical and methodological provisions and substantiate practical recommendations for assessing the level of financial security of banks. The main objectives of the study are: study and analysis of the existing methodological approaches to assessing the level of financial security of banks, identification of advantages and disadvantages of each, on this basis modification of the authors’ own methodological approach, including criteria, measures, indicators, weights. In the course of the research, the following methods were used: abstract-logical analysis - for theoretical generalization and justification of directions and results of the study, systematic and statistical analysis - for analysis and systematization of methodological approaches to assessing the level of financial security of banks, method of expert analysis - for establishing the coefficients of significance of parameters in proposed models, graphical method - for visualization and schematic representation of theoretical and practical results of the study. Bank security zones have been proposed for each level of bank financial security and strategies for value-oriented management have been developed. Results. The existing methods and models for assessing the level of financial security of commercial banks were studied; the advantages and disadvantages of each are identified; an original methodological approach to assessment (criteria, indicators, indicators, weights and algorithm) under the conditions of macroeconomic instability was summarized and proposed. Conclusions. Based on a comprehensive analysis of the works of domestic and foreign scholars and practitioners on the problem of assessing and ensuring the financial security of commercial banks, it has been established that no single comprehensive model for assessing the financial security of banks has been developed yet. All existing models have a high affinity and no systemicity. A system of financial security valuation indicators is proposed, based on a value-oriented approach, and including indicators that integrate into five functional components: capital and resource, credit and investment, income and expense security, currency and value-monetary security of the bank. This approach makes it possible to quantify the impact of each set of indicators on the financial security level of a banking institution, determine its integral level and conduct its operational, tactical and strategic assessment. According to established zones of financial security of banks, value-oriented strategies for managing banks under the conditions of macroeconomic uncertainty are proposed.
