FINRA Updated SIE Exam Questions and Answers by minahil

The correct answer is D, The MSRB (Municipal Securities Rulemaking Board). The MSRB is the primary self-regulatory organization responsible for writing and establishing rules governing the municipal securities market.

Step-by-step, the MSRB creates rules that apply to broker-dealers, banks, and municipal advisors involved in underwriting, trading, and advising on municipal securities. Its goal is to ensure fair practices, transparency, and investor protection in the municipal market.

However, it is important to understand that the MSRB does not enforce its rules. Enforcement responsibility lies with other regulators, primarily FINRA and the SEC. This distinction is frequently tested on the SIE exam.

Choice A, Cboe, is an exchange that focuses primarily on options trading and does not regulate municipal securities. Choice B, FINRA, enforces rules and oversees broker-dealers but does not specifically create municipal securities rules. Choice C, the NYSE, is a stock exchange and not responsible for municipal market regulation.

Thus, the SRO specifically tasked with regulating (rulemaking for) the municipal securities market is the MSRB, making Answer D correct.

A market maker system is best described as multiple market makers competing by displaying bids and offers, which makes choice B correct. Market makers are firms (or participants) that stand ready to buy and sell a security on a regular and continuous basis by quoting two-sided markets—bid (what they will pay) and ask/offer (what they will sell for). In many market structures, multiple market makers post competing quotes, and the best displayed prices help form the national best bid and offer (NBBO) and promote liquidity and price discovery.

Choice A is closer to the concept of a single designated liquidity provider (like a specialist model historically), but even where “designated market makers” exist, modern systems typically still involve competition and additional liquidity providers. Choice C is incorrect because negotiation between individual participants through a designated market maker is not the defining mechanism of a market maker system; market makers post continuous quotes rather than serving as a negotiation channel for each trade. Choice D is also incorrect because orders are not generally sent to one market maker “for review” before being displayed; orders can be routed to various venues, displayed in order books, or executed against quotes depending on market structure.

For the SIE, the key takeaway is that market makers support liquidity by committing capital and quoting markets, and that competition among multiple market makers improves execution quality through tighter spreads and more robust depth. Understanding how bids/asks are displayed and how market participants interact with liquidity providers is central to market structure and trading knowledge.

NASAA is the North American Securities Administrators Association, and its membership is made up of state, provincial, and territorial securities regulators (in the U.S., primarily the state securities administrators). That makes C correct. On the SIE, NASAA is tested as the umbrella organization representing state-level regulators, which are responsible for enforcing state securities laws (“blue sky” laws), registering certain securities offerings when applicable, and registering/licensing investment adviser representatives and other participants under state jurisdiction.

Choice A is incorrect because broker-dealers are regulated entities, not NASAA members. Broker-dealers register with the SEC and are members of self-regulatory organizations like FINRA, but they are not “members of NASAA.” Choice B is incorrect because stock exchanges are marketplaces and are often SROs themselves, but they are not NASAA members. Choice D is incorrect because SROs (such as FINRA or MSRB) are not NASAA members; NASAA represents state-level governmental regulators, not self-regulatory organizations.

This question reinforces an important SIE framework: U.S. securities regulation is shared among federal regulators (SEC), self-regulatory organizations (FINRA, MSRB, exchanges), and state regulators. NASAA serves as a coordinating body for state regulators, promoting uniformity through model rules, policy coordination, investor education, and cooperation among jurisdictions. Understanding NASAA’s membership helps you correctly assign regulatory roles—especially when questions involve blue sky laws, state registration requirements, and state-level enforcement.
