Self-Regulatory OrganizationSRO
A self-regulatory organization (SRO) is a non-governmental body that writes and enforces rules for its own industry, under government oversight. In US markets, FINRA, the NFA and stock exchanges act as SROs.
Governments can't supervise every broker and trade directly, so much day-to-day market regulation is delegated to the industry itself. Self-regulatory organizations write conduct rules, examine members and discipline misconduct — while agencies like the SEC and CFTC watch over them. This entry explains how SROs work, their strengths and their conflicts of interest.

SROs in plain words
An SRO is an organisation formed to regulate a profession or industry, usually non-governmental, creating rules to promote order among members.1
FINRA, for example, is an SRO funded by member firms rather than government spending.2
The NFA is the CFTC-designated self-regulator for the US derivatives industry.3
How an SRO works, step by step
Government delegates
Under oversight of an agency like the SEC. See Securities and Exchange Commission.
Members join
Firms must be members to operate.
Rules are written
Conduct, capital, disclosure.
Members are examined
Regular audits.
Violations are punished
Fines, suspensions, expulsion.
Agency reviews
Rules need regulator approval.
Worked examples
Example 1 — Broker rules
DisciplinedA broker churns a client account.
| SRO | FINRA |
| Possible action | Fine, suspension, restitution |
SROs write and enforce conduct rules for their members.1 See Churning.
Example 2 — Futures firms
NFA actionA futures broker fails to meet capital rules.
| SRO | NFA |
The NFA oversees derivatives firms and ensures members meet their responsibilities.3 See National Futures Association.
Example 3 — Funding
Industry-fundedAn SRO's budget comes from member fees rather than taxes.
| Taxpayer cost | None directly |
Member funding removes the need for government spending.2

Self-regulation
Beginner
SROs are usually non-governmental organisations created to bring order to an industry.1
Checks and balances
Intermediate
FINRA is overseen by a majority-public board to balance industry and public interests.2
Regulatory layers
Advanced
In the US, laws come from Congress, agencies like the SEC and CFTC write rules, and SROs handle day-to-day supervision. See Commodity Futures Trading Commission.
Common mistakes
Thinking SROs are government
They're industry bodies under oversight.
Ignoring SRO tools
BrokerCheck and BASIC are free.
Assuming all firms are members
Offshore firms often aren't.
Expecting SROs to recover losses
That's SIPC or arbitration. See SIPC Protection.
