The paper deals with the analysis of the banking system of Ukraine. It is shown that for Ukraine the frequency and depth of crisis phenomena in the banking sector are exacerbated by the raw material orientation of the economy, underdeveloped domestic market and the circulation of foreign currency (dollarization of the economy). It should be noted that in the pre-crisis during 2006-2007, excessive mortgage lending created a "bubble" in the real estate market, which, comparing its devastating effects, corresponded to this phenomenon in the real estate market in the United States. Although the crisis of 2008-2009 demonstrated the vulnerability of the Ukrainian banking system to numerous economic and political upheavals, no significant changes in banking supervision took place to minimize systemic risks. Restoration of the banking system of Ukraine in 2015-2016 is generally in line with post-crisis trends to streamline the banking system and increase its efficiency in the world. At the same time, the weakness of the institutional environment makes it impossible to use both administrative tools and state development banks to increase productive lending in Ukraine. On the other hand, commercial banks will use refinancing loans instead of private-sector savings to lend. In this case, the probability of the need for financial support from banks increases, which will lead to a significant increase in public debt. Moreover, a system of vector autoregression models has been developed to research the impact of crisis periods on the performance of commercial banks in Ukraine. The simulation results (mainly the analysis of impulse response functions) allow concluding that interbank lending in post-crisis conditions recovers relatively rapidly (with a lag of two years). Lending to non-financial corporations and non-residents showed a decline and recovery only within four years after the crisis. Lending to the general government sector is growing every year, but at the same time loans to other resident sectors are declining. In addition, during the year after the crisis, the volume of deposits in the banking system is demonstrating a decrease. Other variables do not show any response to the crisis.

Abstract. The scientific article is devoted to the development of a methodology for assessing the financial stability of financial corporations using the technology of cascading approach to identify weak areas in their activities and prevent the development of threats to their stable operation. The root causes of their financial instability are selected as the object of financial corporations’ financial stability assessment, and a chain of causal relationships is considered that turn the preconditions into real threats to financial stability or even signs of the corporation’s financial fragility. At the same time, the source of prerequisites for the financial stability of financial corporations in the state and depth of imbalances, which are formed both in the internal and external environment of their operation. It is proved that the tools for assessing internal imbalances in the activities of financial corporations should not be limited to financial imbalances, as their root causes can be concentrated in the organizational, managerial, institutional, conceptual component, in the field of personnel, information, technical support. Therefore, the structuring of imbalances in the activities of financial corporations is proposed to be carried out according to the theory of economic potentials and to identify the following content areas: opportunities, resources, tools, and abilities, the interaction of which forms the potential of financial corporations to operate. A three-stage method for assessing the financial stability of financial corporations has been developed, using a cascading approach, which involves the consistent diagnosis of internal imbalances in the activities of financial corporations: 1) those that arise within each component (resources, means, and capabilities) and are the area of origin of internal threats to their financial stability; 2) imbalances that arise through inter-component interaction (resources-means; abilities-means; resources-abilities) and are the sphere of manifestations of imbalances; 3) those that arise through interaction with the external environment and maximally show the impact of their condition and depth on the level of financial stability. For each of these areas, a set of indicators has been developed and an algorithm for calculating the integrated index of financial stability of a financial corporation has been constructed. The scientific and methodological approach was tested on the example of systemically important banks of Ukraine during 2017—2020, each of which is currently in a continuum of financial stability, and for most banks, there is a growing trend of quantitative measurement of its level. In general, the paper reveals a comprehensive approach to assessing the financial stability of financial corporations, which allows you to systematize those key positions in which the imbalance increases the likelihood of their financial fragility and financial instability.

Abstract. Recently, we heard much more about digitalization and related processes around the world. In other words, digitalization is already an important part of modern trends. The main aspects of digitalization, digital transformation and its impact on the financial services of the banks have been discussed and analyzed in this article. Along with the effect of digitalization on everyone’s life, the influence on financial services of the banks and on their businesses are also important. It is noted that banks need to make changes in their approaches to financial services, business models and strategies in accordance with the new requirements. The paper also focuses on the start of a new digital age in financial markets and the need for the regulator to adopt a new approach over the course of its existence. Formation of the reality of regulators working with wider companies and areas, the need to analyze the larger databases, the importance of extensive use of digital opportunities for more effective run of their functions have been examined. It is stated that the supervisors should be interested in technological development, take the leadership in its application, have to consider possible development trends, new regulations with financial institutions, as well as large bigtech companies. In this regard, the measures taken by the European regulatory authorities, innovations have been analyzed, as well. Emphasizing the importance of defining a common framework approach by the ECB, aspects of the policy set by national regulators within that framework are examined. The obvious positive advantages of new technological solutions application are also discussed. Thus, possibility of modern technological development to create a fertile ground for concealing a number of criminal acts, such as money laundering, terrorism, fraud and tax evasion is noted. Keywords: digitalization, digital transformation, financial supervision, digital finance, financial stability, financial services, risk management.

The paper analyzes the evolution of the introduction of international standards for bank capital regulation. The aim of the research is to study international standards for bank capital regulation and their impact on financial stability and sustainability of domestic banking systems. The 2007—2009 Global Financial Crisis was perhaps the greatest banking and financial crisis since bank failures and the financial panic of the Great Depression in early 1930s. According to academics and professionals, there has been much debate over the last decade as to whether the 2007—2009 banking crisis was primarily a solvency crisis or a liquidity crisis. Capital adequacy of banks today is the main indicator of increasing society’s confidence in banking systems. The flexible and balanced implementation of Basel Committee on Banking Supervision (BCBS) recommendations on the assessment of bank capital adequacy is of particular importance in the context of the deepening economic crisis caused by COVID-19 quarantine restrictions. Regulation of bank capital is primarily settles by the ability to execute basic functions inherent in it. A number of shocks in connection with the crisis require the renewal and search for a new paradigm of regulation, which today is focused on achieving financial stability, overcoming pro-cyclicality, especially in the banking sector. One of the latest developments in the field of bank capital regulation has been the implementation of international banking supervision standards recommended by BCBS, which have been transformed from Basel I, Basel II, Basel III, Basel 3.5 to Basel IV. The new ideology suggests that in times of financial and economic crisis or in anticipation of growing uncertainty in the economy, it is necessary to abandon the idea of bank capital management and the creation of financial reserves to maintain liquidity and stability of financial institutions. These measures will not be able to protect the bank from default and bankruptcy. This ideology has become a new paradigm of effective banking regulation, which can be formulated as an accepted set of three vectors: risk; risk management; risk-oriented supervision.

This paper is devoted to the research of methodological foundations for ensuring financial stability system of credit institutions. The ensuring credit institutions’ financial stability should be based on the value-oriented, risk-oriented approaches and, above all, on the systemic approach. The formation of a system of ensuring financial stability of credit institutions can’t be set only by the organizational and managerial influence on the unbalancing resources of the credit institutions, but also foresee an arrangement of an appropriate informal institutional environment that would serve as a world-view platform for successful implementation of measures on financial stability. Original results. It’s determined the nature of the system of ensuring financial stability of credit institutions, the goals and targets of its functioning, object and subject composition, internal structure and scientific principles that determine its nature and peculiarities of its interaction with the external environment. The main components of the studied system include: informal institutional environment; formal institutional environment; the methodical (cognitive) and supplying subsystems. The informal institutional environment is one. Its quality influence on the effectiveness of measures to ensure the financial stability of credit institutions and the ability to maintain it in a long-term period. Practical relevance. The functionality of the proposed system largely depends on the quality of corporate ethics and the depth of its implementation in the activities of credit institutions. Thus, fraudulent actions, provoked by a business entity (a credit institution), including intentional actions to create a crisis situation in the institution, cannot be turned away by the system. The proposed system is only capable of managing the real threats to financial stability, namely those caused by objective internal or external factors.
