Introduction. Increasing competition between banks requires the introduction of banking products with a new service and economic design, based on modern software, technology and information platforms. Problem. Digitalization is becoming a key trend in conducting business for banks and their corporate clients. The aim of the study is to cluster banks by the level of digitalization and determine the relationship between it and indicators of market power, financial performance and credit risk. Methods. Input normalized indicators for 32 banks of Ukraine, determined using the MINIMAX methodology, were used. The study was based on correlation-regression and cluster analysis. Results. The information base for calculating the digitalization index for banks in the focus group was chosen based on the number of: the number of visitors to banks’ websites, registered users of banks’ mobile applications (including for legal entities and individuals), branded online inquiries, banking self-service devices, subscribers of banks in social media networks. When determining the level of digitalization in corporate business, only two indicators were used: the number of registered legal entities that use mobile bank applications and the number of brand-name online searches for each of them. Three hypotheses were put forward and their empirical verification was carried out, according to the results of which it was established that there is a moderate correlation between the digitalization index and the credit risk indicator and a low correlation between the digitalization index and indicators of financial performance and market power. Among the financial indicators a noticeable correlation was found only between the level of the interest margin and the level of digitalization. Conclusions. For most of the banks in the focus group, a low level of digitalization is inherent in the corporate business. It is proposed to develop a strategy for the development of the corporate business of banks on a new technological platform, which will make it possible to extend digitalization processes not only to typical, but also to exclusive financial services provided to corporate clients, taking into account their individual service.
