Modern foreign studies in the field of banking activities indicate that the banking systems of the advanced countries of the world are currently adapting to a digital model of banking. Despite the fact that the modern stage of development of both global and Russian banking systems is inextricably linked with digital transformation of the customer service processes of credit institutions, researchers have paid little attention to the study of the essence of the digital model of banking services. The inadequate theoretical base of digital banking inhibits orderly and efficient development of Russian banking. In this regard, this article proposes a simulation of banking services, with the aim of selecting the evaluation parameters and criteria of banking models. The study allows to establish the boundaries of the digital banking model, to allocate its characteristic features and peculiarities of functioning. The materials presented in this article should allow the subjects of the banking system to gain a better understanding of the specifics of the development of the modern banking system, and can also serve as a theoretical basis for identification and orientation of the development level of banking services. It promotes coordination of credit institutions and banking systems of the countries of the world aimed at improving the competitiveness and efficiency of their activities in terms of the impact of digitalization on the processes of transformation of banking services. The results of the study can also be the basis for the formation of techniques designed to assess the level of development of banking services and are also a prerequisite for predicting the prospects of further improvement of banking services in order to implement the planned development of banking activities.
