The author developed the definition of factors and preconditions for FSBS research by identifying, along with those already identified, the following ones: awareness of the need for functional, organizational and structural changes in the banking sector (BS) due to the necessity to improve FSBS; finding effective means to counter new challenges for the financial security (FS) in the banking sector (including globalization of financial markets, informatization, digitalization of the economy / digitalization of BS, development of cryptocurrencies, growing the scale of money counterfeiting, introduction of artificial intelligence, the need for sustainable development of the country and the introduction of responsible financing / investment mechanisms); insufficient justification of theoretical and methodological principles, lack of unambiguous methodological approaches to assessing the level of FSBS of the national economy and determining directions / measures to improve it. The interpretation of FSBS as a synthetic category has been clarified, which, as opposed to existing views, focuses on ensuring compliance with a set of financial interests; directly affects the efficiency / effectiveness of banking institutions’ clients / counterparties and other economic agents; is determined by financial autonomy / independence, liquidity, solvency of BS, its financial sustainability / stability, reliability, investment attractiveness, socio-economic efficiency; is a tool to ensure the transformation of BS capital into loans to legal entities and individuals, direct and portfolio investments and such a state of BS, in which the amplitude of undesirable changes in its specific properties is not above / below the indicators’ threshold values. The author improved classification of FSBS types by separating, as opposed to the existing, such a classification feature as «line of action», and the definition of the following varieties based on the classification criteria «goal» as sporadic (ensured by single measures to address the specific task of FSBS compliance at a given time); «resource-functional orientation» – tax; settlement, price, property (security of funds, securities and other assets), security of income and expenses; «type of financial instruments» – security of structured banking products. The interpretation of the concept of «system for ensuring FSBS» is clarified by emphasizing the organic combination of its security subsystems (among which, as opposed to those used, are the following: instrumental, accounting, reporting and diagnostic, forecasting, infrastructure, marketing, social, psychological, law enforcement, software), which are continuously developed on a stable planning basis by the subjects of the system in order to achieve its goals, implement tasks of a conceptual / strategic nature based on the object-oriented approach to ensuring FSBS; the necessity to take a set of optimally alternative and coordinated preventive, current and corrective measures to ensure the financial security of the CB in particular and the BS in general, economic agents which serve them or which are affected by the state of the FSBS, which prevents disruption of existing interconnections. The author comprehensively analyzed the practice of ensuring FSBS for the economy of Ukraine, determined the level of development of the system ensuring FSBS of Ukraine, clarified the factors which influence the ensuring the components of the FSBS of the economy of Ukraine, evaluated the level of FS of domestic, and identified the problems, shortcomings and unresolved issues in ensuring FSBS in Ukraine. Approaches to modeling of the system of ensuring FSBS of Ukraine were described. Conceptual, compositional, step-by-step and development models for building an effective system of ensuring FSBS are proposed for the first time. They give a clear idea of its goals, objectives, objects, subjects, imperatives, measures, principles, criteria; composition as a process of development for such system; stages of its formation and the specifics of its support subsystems. Approaches to evaluation and increase of efficiency of development and functioning of system ensuring FSBS are offered. It is determined that a comprehensive multilevel assessment of such efficiency should include the following assessments effectiveness: of financial security of BS, of protection of national interests and public needs, prevention of banking / financial crises, ensuring FS for clients (households) and business entities) / contractors of CB. It is proved that such assessment should be received by auditing the system ensuring FSBS, conducting quantitative assessment of its level based on the elucidation of the system of relevant indicators and their threshold values.
