SIE practice question: Understanding Trading, Customer Accounts and Prohibited Activities

Understanding Trading, Customer Accounts and Prohibited ActivitiesDifficulty 3/5

A registered representative notices a pattern of transactions with no apparent lawful purpose. Which report does this call for?

  1. AA Currency Transaction Report, which is filed because of the nature of the activity
  2. BAn OFAC blocking report, which is filed because of the nature of the activity
  3. CA Form U4 amendment, which is filed because of the nature of the activity
  4. DA Suspicious Activity Report, which is filed because of the nature of the activity
Show answer and rationale

Correct: D. The SAR is triggered by suspicion; for a broker-dealer it is mandatory when the activity involves at least $5,000, and voluntary below that. The CTR is triggered mechanically by a currency threshold, whether or not anything looks wrong.

  • A — A CTR is driven by a currency amount threshold, not by whether the activity looks suspicious.
  • B — OFAC reporting concerns blocked persons on the SDN list, not suspicious transaction patterns.
  • C — Form U4 reports the representative's own registration information, not customer activity.
