The aim of the study is a theoretical and methodological generalization of the process of strategic management and determination, through strategic planning, of ways of development of system important banks of Ukraine under conditions of uncertainty of their functioning environment. As a result of the study of foreign and domestic experience, the theoretical and methodological concept of strategic planning of the banking system is formulated. The authors analyze the goals, missions and visions of the strategies of system important banks, assess the state of development of system important banks in Ukraine in the current conditions and identify the key areas of strategic planning. It is found that system important banks of Ukraine occupy a predominant share in the structure of both certain types of banking income and financial performance. In addition, it is determined that strategic planning should be based on the reliability and completeness of economic indicators and non-financial indicators. In particular, the indicators of the bank’s share in the activity among banking structures are important for characterizing its competitive position and the level of efficiency of its strategy among competitors. It is researched that system important banks are predominant in the banking services market, and their network of branches is widely distributed. The strategic development of these banks should be aimed at the possibility of retaining this share of the banking services market. The authors improve the theoretical and methodological approach to the strategic planning process in a bank on the principles of introducing an inclusive component of further development, which will provide for a sustainable accelerated growth of the country’s economic power on the basis of financial inclusion, a radical increase in the welfare of individual members of society and society as a whole. It is specified that such approaches to organizing the formation of strategies of system important banks will also ensure sociopolitical stability and form an appropriate level of national security.

Researching the problems of banking supervision in the course of the policy of cleaning the banking system of Ukraine is of particular importance. The issues of efficiency of regulation of the activities of commercial banks with the help of economic standards of the NBU remain topical. The article is aimed at a theoretical-methodical substantiation of the NBU economic standards system and identifying the peculiarities of their application as instruments for regulating the banking activities. The state of compliance with capital, liquidity and credit risk standards by commercial banks of Ukraine is examined. A correlation and regression analysis of the impact of credit risk standards on the volumes of overdue credit arrears of banks is carried out. Ways to improve the system of regulation of the activities of commercial banks based on the principles developed by the Basel Committee on Banking Supervision are proposed. A further proposal is made as to introducing an additional economic standard for the regulation of credit risks, which would assess the risks of repayment of loans. In addition, it will be expedient for Ukraine to build a conceptual banking supervision, which will ensure close interaction of components in order to improve the efficiency of banking institutions. A comprehensive system of banking supervision should diagnose the level of risks and implement systems of their management at the level of each separate banking institution.

The share of the largest banks is growing in Ukraine. Since 2016, Ukraine's banking system has been similar in terms of concentration to Belgium, Denmark and Spain. An ambiguous influence on the level of competition and on the efficiency of the largest banks is exerted by a significant share of the state in the banking system. It is established that the size of the profitability of the banking system of Ukraine largely depends on the level of concentration and has a sufficient degree of closeness. At the same time, net income in the banking system of Ukraine strongly depends on the level of concentration of net assets in banking. It is proposed that state regulatory measures for the concentration of bank capital should be aimed at creating a competitive environment. It is expedient for Ukraine to take into account and implement the experience of the EU and other developed countries, which takes into account the existence of various forms of competition. Competition policy options take into account the need to address mergers and acquisitions of banks.

The research is aimed at theoretical and practical aspects of financial planning of enterprises in conditions of volatility and instability of the external environment. Based on the generalization of approaches to the essence and the meaning of financial planning, its semantic characteristics are determined in terms of methodology in both broad and narrow context. The process of evolution of financial planning is considered from the point of view of formation of systems of financial economic activity management of enterprises, three stages of its genesis with specification of advantages and disadvantages are distinguished. The principles, types and methods of planning are systematized. The stages of financial planning at enterprises are distinguished and their role in balancing financial stability in the process of formation, accumulation, distribution and use of financial resources is determined. Based on the stages of financial planning, three main subsystems of activity planning (strategic forecasting, ongoing financial planning and operational planning of financial activities) are described. On the basis of the analysis of existing problems in financial management in case of instability and recurrence of crisis phenomena, a mechanism for organizing financial planning at enterprises is proposed. The need to improve the effective generation of cash flows in the long term is distinguished, taking into account strategic and long-term financial plans based on the scenario financial planning method.
