1.1 Regulatory Bodies
The U.S. securities industry operates under a layered regulatory structure. Understanding who regulates what is essential for the SIE exam — and for your career in finance.
The Regulatory Hierarchy
Think of securities regulation as a pyramid. At the top sits Congress, which passes laws like the Securities Act of 1933 and Securities Exchange Act of 1934. Below that, federal agencies and self-regulatory organizations (SROs) enforce these laws and create additional rules.
SEC — Federal Agency — Overall securities markets
FINRA — Self-Regulatory Organization — Broker-dealers and their employees
MSRB — Self-Regulatory Organization — Municipal securities
SIPC — Non-profit Corporation — Customer asset protection
Federal Reserve — Federal Agency — Monetary policy, bank holding companies
Securities and Exchange Commission (SEC)
The Securities and Exchange Commission (SEC) is the primary federal regulator of the securities industry. Congress established it in 1934 following the stock market crash of 1929. According to the SEC, the agency oversees approximately $120 trillion in securities trading annually on U.S. equity markets.
Key Functions
Enforces federal securities laws — The SEC investigates and prosecutes violations of securities laws, including fraud, insider trading, and market manipulation
Reviews registration statements — Companies must register securities with the SEC before offering them to the public
Oversees market participants — The SEC supervises exchanges, broker-dealers, investment advisers, and SROs like FINRA
Protects investors — Through disclosure requirements, the SEC ensures investors receive accurate information
In Practice
When a company wants to go public through an IPO, it files a registration statement (Form S-1) with the SEC. The SEC staff reviews this document for compliance with disclosure requirements — but importantly, the SEC does not approve the investment or judge its merits, so an effective registration does not mean the investment is safe or recommended.
Financial Industry Regulatory Authority (FINRA)
FINRA is the largest self-regulatory organization (SRO) overseeing broker-dealers in the United States. It operates under SEC supervision but is not a government agency — it's a private, non-profit organization. According to FINRA's 2024 Annual Report, the organization regulates approximately 3,400 broker-dealer firms and 624,000 registered representatives across the United States.
Key Functions
Licenses securities professionals — FINRA administers qualification exams like the SIE, Series 7, and Series 63
Creates and enforces rules — Broker-dealers must follow FINRA rules on sales practices, supervision, and customer protection
Monitors trading activity — FINRA surveils markets to detect insider trading, manipulation, and other violations
Examines member firms — Regular compliance inspections occur at least every four years
Important Distinction
FINRA regulates broker-dealers and their registered representatives, not investment advisers. Investment advisers are regulated by the SEC or state regulators depending on their assets under management.
Municipal Securities Rulemaking Board (MSRB)
The Municipal Securities Rulemaking Board (MSRB) creates rules governing transactions in municipal securities (bonds issued by states, cities, and other local governments).
Key Functions
Writes rules for municipal securities dealers and municipal advisors
Operates EMMA — The Electronic Municipal Market Access system provides free public access to municipal bond information
Does NOT enforce its own rules — FINRA and the SEC enforce MSRB rules for broker-dealers; banking regulators enforce them for banks
On the Exam
Remember: The MSRB is a rulemaking body, not an enforcement body. This distinction frequently appears on the SIE.
Securities Investor Protection Corporation (SIPC)
SIPC (Securities Investor Protection Corporation) is a non-profit corporation that protects customers if a brokerage firm fails. Most registered broker-dealers must be SIPC members; the law excludes, for example, firms whose principal business is outside the United States and firms whose business is only distributing mutual fund or UIT shares, selling variable annuities or insurance, or advising registered investment companies. SIPC protection covers up to $500,000 per customer in each separate capacity (including a $250,000 limit for cash claims); accounts held in the same capacity are combined. SIPC reports that since its creation in 1970 it has advanced $3.6 billion to make possible the recovery of $143.8 billion in assets for an estimated 773,000 investors.
Coverage Details
What SIPC Covers: Securities (stocks, bonds); Cash in brokerage accounts; Up to $500,000 per separate capacity; Including $250,000 for cash
What SIPC Does NOT Cover: Market losses; Bad investment advice; Sales of worthless securities; Commodity futures
Critical Point
SIPC is not like FDIC insurance for banks. SIPC only protects against broker-dealer failure — if the firm goes bankrupt and your assets are missing. It does not protect you if your investments lose value.
Federal Reserve Board
The Federal Reserve (often called "the Fed") is the central bank of the United States. While not primarily a securities regulator, it plays important roles relevant to the SIE.
Key Functions
Sets monetary policy — Controls interest rates and money supply, which affects securities prices
Regulates margin requirements — Regulation T governs how much investors can borrow to buy securities
Supervises bank holding companies — Including those that own broker-dealers
How Regulators Work Together
These regulators don't operate in isolation — they coordinate oversight:
1. SEC oversees FINRA and approves its rules
2. FINRA enforces SEC rules and its own rules at broker-dealers
3. MSRB writes rules that FINRA and the SEC enforce
4. SIPC steps in only when a broker-dealer fails
Real-World Example
If a registered representative at a broker-dealer commits fraud selling municipal bonds:
FINRA would investigate the rep's conduct and potentially bar them from the industry
SEC could bring civil charges
MSRB rules would determine what standards were violated
SIPC would only be involved if the broker-dealer itself failed
Key Takeaways
The SEC is the ultimate federal authority over securities markets
FINRA directly regulates broker-dealers and their employees
The MSRB writes rules for municipal securities but doesn't enforce them
SIPC protects customers when brokerage firms fail — not from market losses
The Federal Reserve influences markets through monetary policy and margin rules
Frequently Asked Questions
Q: Which organization administers the SIE exam and other securities qualification exams?
A: Financial Industry Regulatory Authority (FINRA). FINRA administers qualification exams including the SIE, Series 7, Series 63, and others. The SEC oversees FINRA but does not directly administer licensing exams. The MSRB only writes rules for municipal securities, and SIPC handles customer protection when firms fail.
Q: SIPC protection covers which of the following?
A: Missing assets when a brokerage firm fails. SIPC protects customers when a SIPC-member brokerage firm fails and customer assets are missing — up to $500,000 per customer in each separate capacity. SIPC does NOT cover market losses, bad advice, or being sold worthless securities. Fraud by a representative at a firm that has not failed is a matter for FINRA and the SEC; SIPC acts only when the firm fails and assets are missing, even if theft or unauthorized trading caused the loss.
Q: Which statement about the MSRB is correct?
A: The MSRB writes rules for municipal securities but does not enforce them. The MSRB is a rulemaking body that writes rules for municipal securities transactions, but it does not enforce those rules. Enforcement is handled by FINRA (for broker-dealers) and the SEC. The MSRB is a self-regulatory organization, not a government agency.
