This article studies the possibility of using the correspondence relations between banks as mechanisms for legalisation of funds of an obscure or criminal origin, in times of economic instability, local wars and introduced restrictive sanctioning action in respect of certain economic regions as well as the methods for prevention of such attempts. It is impossible to provide an efficient system for monitoring and registering the financial transactions of suspicious customers or these originating from areas with possibilities of tax planning, without developed systems for automation of selection and processing of bank information.
A particular attention is paid to the methods using information technologies for processing the database containing the transactions carried out through iteration procedures, as well as to the heuristic methods for unsystematic transactions containing suspicious features between correspondent banks for cash flow circulating in various segments of the financial system.

Key words

international financial and economic sanctions; steady management; correspondent banks; relational base; associative rules; information technologies; heuristic methods.
