Theoretical approaches of domestic scientists to the definition of "digital economy" have been worked out in the article. In order to determine the background for the bank digital business model forming, indices reflecting the digital development level of countries have been analyzed. The following indices were analyzed: Global Competitiveness Index (GCI), European Innovation Scoreboard (EIS) and World Digital Competitiveness Ranking (WDCR). The Global Competitiveness Index makes it possible to assess both the level of financial market development and the country's innovative capabilities. An analysis of these indices in the period 2016-2019 has showed that there are a number of factors hampering the innovative development of Ukraine economy, as well as lack of analytical information about the results of innovative activity of business and banks that indicate that there is no suitable socio-economic environment capable for adopting and using the bank digital business model. Results of the conducted analysis showed that the level of banking system development in Ukraine, as well as its competitiveness is low, but the innovative potential of the country is significant, which indicates on the creation of conditions for the introduction of information and communication technologies, in particular, by banks as they interact with all sectors of the economy and population and can accelerate the country's innovative development. Ukraine is only at the stage of creating the foundations for the digital economy and the implementation of financial technologies by banks is unlikely to produce the expected result due to the lack of willingness of the individuals and business to make such changes. Conclusions on the bank digital business model forming in Ukraine have been made.
