국제적 자금세탁 의심거래에 대한 소셜 네트워크 분석(SNA): 미국 재무부의 의심거래보고(SAR) 문건을 중심으로

Social network analysis is a very useful tool for analyzing relationships between entities and entities, such as people and people or companies. The nature of the money laundering process has features that go through a large number of intermediaries and are integrated into the beneficial owner in the final stage, making it very useful to use social network analysis. Until now, leading researchers have conducted research with theoretical research or some data on social network services. In response, leading researchers have called for follow-up studies on highly connected financial networks, such as financial transaction data. Therefore, the research team analyzed the data of The Financial Crimes Enforcement Network (FinCEN) under the US Treasury Department announced by the International Association of Investigative Journalists (ICIJ) on September 20, 2020. This data is a Suspicious Activity Report (SAR) report that a financial company participating in the US international remittance network reported to the Financial Crimes Enforcement Network on transactions with reasonable suspicion among clients' financial transactions. This is the first study to analyze the Suspicious Transaction Report(SAR) data actually reported in anti-money laundering and law economics studies. Through this study, the researchers were able to confirm the characteristics of the homophily of members of suspicious money laundering transactions and the social exchange perspective of accomplices.
