“Wall Street” isn’t governed by one master law—it’s a stack of federal statutes, agency rules, and self-regulatory rulebooks that together regulate (1) raising capital, (2) trading/market structure, (3) intermediaries, (4) asset management, (5) derivatives, (6) bank safety, and (7) fraud/abuse.
The core legal pillars (U.S. federal)
- Securities Act of 1933 (“’33 Act”): governs new offerings (IPOs, public bond offerings). The basic idea is register or qualify for an exemption, with heavy disclosure.
- Securities Exchange Act of 1934 (“’34 Act”): governs secondary trading markets, creates SEC authority over exchanges/broker-dealers, and anchors the big anti-fraud regime (notably Rule 10b-5 under Section 10(b)).
- Investment Company Act of 1940: regulates registered funds (e.g., mutual funds/ETFs), focusing on structure, disclosure, and conflicts.
- Investment Advisers Act of 1940: regulates investment advisers (RIA world) and is the backbone for adviser fiduciary principles.
- Commodity Exchange Act (CEA): regulates futures (and, via later amendments, much of the derivatives framework), administered by the CFTC.
- Dodd-Frank Act (2010): post-2008 overhaul—systemic-risk architecture (e.g., FSOC) and major swaps regulation (CFTC rulewriting, clearing, dealer rules, etc.).
The regulators you keep seeing
- SEC: disclosure, public companies, broker-dealers, exchanges, funds, market integrity.
- CFTC: futures and much of swaps/derivatives.
- FINRA (SRO): the front-line rulebook and supervision for broker-dealers, under SEC oversight.
- Systemic/consumer/bank plumbing: Dodd-Frank created/reshuffled parts of the structure (notably CFPB and systemic-risk coordination via FSOC).
How this shows up in day-to-day “Wall Street” rules
- Market structure & trading venues: exchanges and alternative trading systems (ATSs) are regulated (Reg ATS definitions and requirements; Reg NMS is a key market-structure rule set).
- Broker conduct with retail customers: Regulation Best Interest (Reg BI) sets a “best interest” standard for broker-dealer recommendations to retail customers.
- Short selling mechanics: Regulation SHO (locate/close-out and related requirements).
Don’t forget: state law still exists
Even with heavy federal preemption in many areas, states have their own securities antifraud/registration regimes—commonly called “blue sky laws.”
