Which of the following is a red flag that cash transactions are being structured?

• A. A single large cash deposit.
• B. Electronic wire transfers only.
• C. Transactions in multiple currencies.
• D. Cash transactions occurring in a short duration of time.

Answer: (D)

Structuring, also called smurfing, is when a cash activity is split into multiple smaller deposits to avoid triggering reporting requirements. A pattern of many cash transactions in a short period is a telltale red flag because it suggests an attempt to stay under reporting thresholds and conceal the true size of the activity. This clustering of cash deposits can prompt investigators to scrutinize for illicit intent and potential money laundering. In contrast, a single large cash deposit would typically attract attention on its own but does not demonstrate the deliberate fragmentation that defines structuring. Electronic transfers and transactions in multiple currencies can occur for legitimate reasons and don’t inherently signal structuring. Therefore, observing cash deposits occurring in a short duration of time best indicates structuring.
