The article examines legal and organizational mechanisms for improving the system of monitoring financial transactions in order to identify and assess corruption risks. Based on an analysis of the current anti-corruption legislation of the Russian Federation, international standards of the FATF and UNCAC, as well as contemporary law enforcement practice, systemic shortcomings in the existing financial monitoring system in the field of anti-corruption are identified. A set of legal, institutional, technological, and procedural measures for its optimization is proposed. Particular attention is paid to a risk-based approach to monitoring transactions of public officials (PDL), the digitalization of mechanisms for detecting suspicious transactions using big data and artificial intelligence technologies, and the development of interagency cooperation in this area.
