Printing money is the main function of central banks. However, the impact that they have on the economies of their states is difficult to underestimate. Wrong decisions made by the leadership of the Central Bank, if not immediately, then in the long term will adversely affect the financial system of the whole country. The consequences will be felt by everyone - from large business to an ordinary citizen.
