Suspicious Behaviour in High-Value Cash Transactions
he use of cash in high-value transactions remains one of the most significant money laundering risks worldwide. In the UAE, where sectors like gold and jewellery, real estate, and luxury goods trading often deal with large sums, regulators such as the Ministry of Economy (MoE) and the Central Bank (CBUAE) expect businesses to carefully monitor, record, and report suspicious cash activity.
It highlights the behaviours and patterns that should raise red flags when dealing with high-value cash transactions.

6. Large Cash Payments – Buying high-value goods (e.g., property, gold bars, diamonds) with bulk cash.
7. Multiple Small Payments (Structuring/Smurfing) – Splitting large transactions into smaller amounts to avoid reporting thresholds.
8. Overpayment and Refund Requests – Paying more than required and asking for a refund via cheque or bank transfer.

6. Actions to Take When Suspicious Behaviour is Detected
• Document the Behaviour – Record all details in the internal system.
• Escalate Internally – Report to the MLRO/Compliance Officer without delay.
• File STR/SAR – If suspicion is confirmed, the MLRO files a report through goAML.
• Avoid Tipping Off – Never inform the customer about the suspicion or reporting.
• Update Risk Assessments – Use identified cases to strengthen ongoing AML controls.
