Structuring (Smurfing)

Financial TransactionsVERIFIED

(1) Structuring, also known as “smurfing,” is the practice of breaking down large financial transactions into multiple smaller transactions to deliberately avoid triggering BSA reporting requirements such as CTRs. In a casino context, structuring typically involves a patron conducting a series of cash buy-ins or chip redemptions, each kept just under $10,000 to evade CTR filing. Examples include redeeming $9,000 in chips at one cage window and $6,000 at another, or making repeated $9,000 cash deposits over multiple days. Structuring is itself a federal crime under 31 U.S.C. § 5324, regardless of whether the underlying funds are from illegal activity. Casinos must have systems to detect structuring patterns and file SARs when identified. (2) The practice of breaking a large currency transaction into multiple smaller transactions, each below the $10,000 CTR reporting threshold, to evade detection and avoid mandatory reporting requirements. Structuring is illegal regardless of whether the underlying funds were obtained legitimately. Common structuring indicators include multiple deposits or withdrawals just below the threshold, transactions conducted across multiple shifts or casino locations, and the use of multiple individuals to conduct related transactions. Casino staff and surveillance must be trained to recognize and report structuring patterns.

In practice

Also known as “smurfing” in some contexts, though SMURFing typically refers to using multiple individuals (“smurfs”) to conduct transactions. FinCEN specifically identifies structuring as a reportable activity. Even if the funds are legally obtained, deliberately evading reporting thresholds is a criminal offense. Casinos should continue transactions and file SARs without alerting the patron.
