The deposits that looked like smurfing

Structuring (also called smurfing) is breaking large cash sums into deposits below the $10,000 reporting threshold to evade currency-transaction reporting. It is a real and serious laundering technique — and a favorite trigger of automated AML alerts.

But the same pattern — frequent sub-threshold cash deposits — is the normal heartbeat of legitimate cash-intensive businesses: laundromats, car washes, restaurants, convenience stores. Tell them apart and you stop drowning your analysts in false-positive filings.

• A threshold-based rule sees 'many deposits just under $10k' and fires a structuring alert — it can't see the context that makes the pattern innocent.
• A verified storefront, daily takings that match expected revenue, and the payroll/supplier/tax outflows of a real going concern are exactly the signals a blunt rule ignores.

• Deposits consistent with a real, verifiable operating business (location, licensing, hours).
• Cash in roughly matching expected daily revenue, with normal seasonality — not lumpy injections.
• Corresponding outflows of a real business: payroll, rent, suppliers, taxes.
• No layering and no rapid pass-through to unrelated third parties or off-ramps.

• Baseline cash-intensive customers against their declared business type before alerting on sub-threshold deposits.
• Weight context (verified storefront, matching outflows) so genuine businesses don't generate a SAR every week.
• Reserve the structuring escalation for deposits that lack a legitimate business explanation or show layering.
