The article presents a modern view of understanding of "financial market" concept, as the development of financial technologies gradually influences the change of paradigm of its functioning, new financial institutions, institutions of market infrastructure, financial instruments are emerging, as well as the development of forms of alternative financing. On the base of the systematization, it is determined that the term "financial market" in the current scientific literature is considered from three positions, first as a mechanism of distribution of financial resources, secondly, as a system of economic relations, and thirdly as a set of markets and institutions. As a result of the research on the contrary to the popular opinion that the financial services market and the financial market are two separate markets, it has been substantiated that the financial services market is a part of the financial market, because financial instruments are formed through the provision of financial services. The financial market and the market of financial services have common subjects - financial intermediaries (banks, insurance companies, non-government pension funds, investment funds, etc.), but at the same time the objects of these two markets are different. Financial instruments are objects for financial markets, and services – for the market of financial services.
Through the process of financial services providing, financial intermediaries ensure the fulfilment of the basic function of the financial market, which is the redistribution of financial resources in the economy, thereby creating financial assets, liabilities, etc., which is the basis for the formation of financial instruments. Taking into account of the impact of fintech on the development of the financial market, author's definition was presented in this work as a system of financial institutions (market subjects), which create the conditions for transactions with financial instruments of economic agents (market objects) using appropriate infrastructure and financial technologies.
