Supervision of Municipal Securities Activities
The supervisory system
MSRB Rule G-27 is the backbone of this domain. Every dealer must adopt written supervisory procedures (WSPs) reasonably designed to achieve compliance with MSRB rules and the federal securities laws, and must designate one or more municipal securities principals (a Series 53 holder) with authority to carry them out. The principal's core duties are: reviewing and endorsing municipal securities transactions and customer confirmations promptly after execution (the WSPs must state the time period); inspecting each office of supervisory jurisdiction at least annually; reviewing customer complaints and the disciplinary history of associated persons; ensuring qualification and training; and maintaining a documented, enforced supervisory control system.
Traps
- Verbal supervision. Oral instructions, or practices never written into the WSPs, fail G-27 even where no customer was harmed.
- The guarantee myth. Supervision is judged by the reasonableness of the system and by evidence of follow-through, not by whether every violation was prevented.
- Scope confusion. The mandatory annual inspection covers each OSJ; other offices follow a schedule set in the WSPs. Do not confuse G-27 (dealer supervision) with G-44 (municipal advisor supervision) or G-3 (qualification).
- Delegation. A principal may delegate review tasks to competent personnel but cannot delegate accountability.
Rule of thumb / worked example
If the WSPs say the principal reviews each trade within one business day of execution, and a trade executed Monday is initialed Thursday, the firm is out of compliance with its own procedures even though the trade itself was clean. The review log is the exam evidence: it should show who reviewed, when, and what exceptions were escalated.
