Questions about objective necessity of financial mediators for commercial banks began to be actively discussed in the middle of the 20th century. In recent years discussions about the role and functions of banks and about their possible disappearance become active.

The purpose of the article is to assess possibilities for commercial banks development in the context of active implementation of financial technologies. The objectives are to characterize benefits and risks associated with the use of fintech for commercial banks, determine directions and stages of their implementation by banks (from providing separate online services to creating ecosystems), identify possibilities for banking business under increasing competitiveness with fintech companies.
