Organization of effective cash circulation throughout the territory of the Republic of Kazakhstan is one of the main tasks of the National Bank of Kazakhstan (NBK). Against the backdrop of the rapid development of non-cash payments, cash continues to serve as an important payment instrument for the population. Research on the use of cash and non-cash money by the population has been regularly conducted in European countries for more than 10 years, in Germany - every three years, in Russia - every year. In the context of modern trends and challenges, there is a need for research in Kazakhstan. In Kazakhstan, a survey on payment preferences of economic entities was conducted for the first time by the National Bank. At the same time, the study was conducted not only among the population, but also among entrepreneurs. In Kazakhstan, despite the development of non-cash payments, in parallel, there is a steady increase in the amount of cash in circulation, which is also typical for developed countries. Accordingly, the purpose of the study is to determine the trends in the development of cash circulation, identify the factors that form the demand for cash, as well as study the use of cash and its nominal structure by economic entities.
