The article, along with theoretical views regarding the concept of money laundering methods through the banking system, is aimed to study its significance for the development of the country, in particular of the regions, and draw conclusions on the importance of timely economic security. To achieve this goal, a three-stage model of money laundering was used, i.e. money laundering using bank promissory note transactions, money laundering in the securities market, and methods of money laundering using separate accounts.
