Introduction. The result of the global financial crisis is the process of transformation of banking supervision aimed at increasing the efficiency of banking risk management and improving mechanisms for dealing with various risk factors. The transformation of the banking surveillance system in the global aspect has defined a set of measures which are constantly monitored by international regulators. The improvement the supervisory methodology is mainly governed by the recommendations of the Basel Committee on Banking Supervision and currently involves introduction of new standards and approaches to regulating and supervising banks based on risk diversification, development of regulations and prompt application of measures to influence banks activities in case of excessive risk build up and increasing threats to the realization of systemic risk, implementation of internal control recommendations at banks aimed at identifying and minimizing the aggregate level of their risk, improvement of analytical rules and procedures and agreeing on intra-bank risk assessment techniques. Purpose. This paper presents the results of the possibility of using the cluster approach in the process of investigating the relationship between the ownership structure and risk profile of Ukrainian banks and, on this basis, improving their supervision.

It is substantiated that most of the existing methods and models for assessing the development of the banking sector of the economy do not take into account the competitive conditions for banks of different groups – with national capital and foreign banking groups. This determines the relevance of the study to improve the methodical approach to statistical assessment of competitive conditions in the development of the banking sector in the presence of foreign banks in the financial market. The scientific work proposes to assess the competitive conditions in the banking sector, in particular those created for domestic banks under the influence of foreign presence, by the level of the coefficient of competitive internalization. Eight gradations of the coefficient level were established by the expert method. Due to the use of mathematical calculation method and official statistics, it was found that the level of competitive internalization in the banking sector of Ukraine over the past decade is mostly dangerous, with a tendency to deteriorate. The coefficients of competitive internalization for the banking sectors of the Commonwealth of Independent States and the European Union have been calculated. It is determined that the level of influence of foreign banks in the banking sector of Ukraine can be compared with the conditions of competitive development of national banks of Moldova and Slovenia. The use of competitive internalization coefficient in practice as a statistical data will create a basis for determining the direction of integration processes. We are convinced that the integration of Ukrainian banks into the banking sector of Moldova or Slovenia is possible.
