The appearance and normal development of the society is determined by a number of interrelated factors. To understand the essence of these factors, each factor should be analyzed separately. The currency is one of the indispensable socio-economic instruments of an economy. At first sight, it may look unessential. But when we look at the effects that can appear in case of poor administration (such as inflation, deflation, etc.), we realize that it is not so. Thus, inflation is a general misbalance of the economy caused by the appearance or increase in the discrepancy between the money mass and the supply of goods compared with the previous situation. The process can be noticed through two major interconnected trends: a general rise in prices and a fall in the value of money.
