Self-Regulatory Organizations (SROs)

  • Created by the securities industry to regulate itself
  • Operate under SEC oversight — SEC has final authority

FINRA

  • SRO for all broker-dealers
  • Writes and enforces rules for B/Ds and their associated persons
  • Operates BrokerCheck (public disclosure system)
  • Administers licensing exams (SIE, Series 7, 63, 66, etc.)
  • Handles arbitration and mediation of disputes
  • Can fine, suspend, bar, or expel members

NYSE / Exchanges

  • SROs for their own listed securities
  • Set listing standards
  • Monitor trading on their exchange

MSRB

  • SRO for municipal securities market
  • Writes rules — does NOT enforce
  • FINRA enforces MSRB rules for B/Ds
  • Banking regulators enforce for banks
  • Operates EMMA (Electronic Municipal Market Access)

Arbitration vs Mediation

  • Arbitration: Binding decision by arbitrator panel
  • Mandatory for industry disputes
  • Required if in customer agreement (pre-dispute arbitration clause)
  • Customer can choose: all public, or majority public + one industry arbitrator
  • Decision is FINAL — very limited appeal rights
  • Mediation: Voluntary, non-binding negotiation with mediator
  • Parties must agree to participate
  • Mediator facilitates but does NOT decide

Regulatory Hierarchy

1. Congress (writes securities laws)

2. SEC (enforces federal securities laws, oversees SROs)

3. SROs — FINRA, exchanges, MSRB (self-regulate under SEC)

4. State regulators (Blue Sky Laws — state securities regulations)

Key facts to memorize

  • SROs: FINRA (B/Ds), NYSE (exchange), MSRB (munis)
  • MSRB writes rules, cannot enforce — FINRA enforces for B/Ds
  • Arbitration: binding, final; Mediation: voluntary, non-binding
  • SEC oversees SROs; SROs regulate members
  • Blue Sky Laws: state-level securities regulations
  • FINRA can fine, suspend, bar, or expel members

Mnemonics that stick

  • "SRO = Self-Regulate with Oversight (from SEC)"
  • "FINRA = the cop on the beat for broker-dealers"
  • "Arbitration = Already decided (binding, final); Mediation = Maybe we can work it out (voluntary)"
  • "Blue Sky Laws = state laws (blue sky = each state has its own sky/rules)"
  • "MSRB writes, FINRA enforces (for B/Ds) — like a teacher writes the test but the principal grades it"

Exam traps

  • MSRB writes rules but CANNOT enforce them — enforcement is by FINRA (for B/Ds) or banking regulators
  • Arbitration decisions are FINAL and BINDING — extremely limited appeal rights
  • Mediation is VOLUNTARY and NON-BINDING — either party can walk away
  • SEC oversees SROs but does NOT directly regulate individual reps (FINRA does)
  • Blue Sky Laws are STATE regulations — federal securities laws are separate
  • Pre-dispute arbitration clauses in customer agreements are enforceable
