18.1 State Regulation, McCarran-Ferguson, and NAIC
Key Takeaways
- The McCarran-Ferguson Act (1945) gives states primary authority to regulate and tax the business of insurance.
- Federal antitrust law applies to insurance only to the extent a state does not regulate the conduct in question.
- Each state insurance department is led by a Commissioner, Director, or Superintendent who licenses, examines, and disciplines.
- The NAIC is a private nonprofit of regulators with no direct power; it drafts model laws states may adopt, modify, or reject.
- Certificate of authority, solvency monitoring, and market conduct exams are the core tools of insurer oversight.
Why insurance is state-regulated
Unlike banking or securities, the business of insurance is regulated chiefly by the 50 states, the District of Columbia, and the U.S. territories. There is no single federal insurance regulator. This structure traces to a 1944 Supreme Court case and the federal statute Congress passed to answer it.
In United States v. South-Eastern Underwriters Association (1944), the Court held that insurance sold across state lines was interstate commerce and therefore reachable by federal antitrust law. That ruling threatened to displace the existing state-based system overnight.
The McCarran-Ferguson Act of 1945
Congress responded with the McCarran-Ferguson Act (15 U.S.C. 1011-1015). Its core declaration is that the business of insurance is subject to the laws of the several States. It did not ban federal regulation; it set a default that state law governs insurance and that federal statutes do not displace state insurance law unless Congress says so specifically.
Four exam-tested provisions
| Provision | What it means |
|---|---|
| State primacy | States hold the primary power to regulate and tax insurance. |
| Antitrust exemption | Insurance is exempt from federal antitrust laws (Sherman, Clayton, FTC Acts) to the extent the state regulates that conduct. |
| Reverse preemption | A federal statute does not override state insurance law unless the federal law specifically relates to insurance. |
| Contingent federal reach | If a state fails to regulate a practice, federal antitrust law can apply to fill the gap. |
Trap: McCarran-Ferguson does not make insurance immune from all federal law. Acts that expressly govern insurance (HIPAA, ACA, ERISA, Gramm-Leach-Bliley, Fair Credit Reporting Act) still apply. The 2021 Competitive Health Insurance Reform Act even repealed the antitrust exemption for health and dental insurers.
Under the McCarran-Ferguson Act, federal antitrust laws apply to the business of insurance:
The state insurance department and the Commissioner
Every state has an insurance department (also called a division or office) funded mainly by fees and assessments on insurers. Its chief officer is the Insurance Commissioner (titled Director or Superintendent in some states). In most states the Commissioner is appointed by the governor; a minority of states elect the Commissioner.
Commissioner powers learners must know
- Rulemaking: issue regulations that interpret and implement insurance statutes.
- Licensing: grant, deny, suspend, or revoke producer and insurer licenses.
- Examination: inspect an insurer's books, records, and market conduct.
- Enforcement: issue cease-and-desist orders, levy fines, and order restitution.
- Receivership: take over (rehabilitate or liquidate) an insolvent insurer.
The Commissioner is an administrative officer, not a court. Decisions follow a notice-and-hearing process and are subject to appeal.
Insurer authorization and solvency
Before writing business, an insurer must hold a certificate of authority from the state. Insurers are classified by where they are chartered:
| Term | Meaning |
|---|---|
| Domestic | Chartered in the state where it is doing business (e.g., a Missouri insurer in Missouri). |
| Foreign | Chartered in another U.S. state. |
| Alien | Chartered in another country. |
| Admitted (authorized) | Holds a certificate of authority in the state. |
| Nonadmitted (unauthorized) | Lacks a certificate; may write only surplus-lines business under special rules. |
Solvency is the regulator's central concern. Tools include minimum capital and surplus requirements, risk-based capital (RBC) ratios, annual financial statements, periodic financial exams, and the state guaranty association that pays covered claims (up to statutory limits) if an admitted insurer fails.
The NAIC and model laws
The National Association of Insurance Commissioners (NAIC), founded in 1871 and headquartered in Kansas City, is a private, nonprofit body whose members are the state commissioners. The single most important fact: the NAIC has no direct regulatory authority. It cannot license, fine, or compel a state to do anything.
Its main product is the model law (or model act/regulation) — template legislation drafted to encourage uniformity. A model law has no legal force until a state legislature adopts it, and a state may adopt it in full, modify it, or reject it. Key NAIC models behind later sections include the Unfair Trade Practices Act, the Unfair Claims Settlement Practices Act, the Life Insurance and Annuities Replacement Model Regulation, and the Suitability in Annuity Transactions Model Regulation.
The NAIC also runs an accreditation program that pushes states to meet minimum solvency-oversight benchmarks, and shared databases (such as producer-licensing systems) that make multistate compliance practical.

Admitted vs. Non-Admitted Insurers
State regulation centers on authorization. An admitted (authorized) insurer has received a certificate of authority to do business in the state and is backed by the guaranty association. A non-admitted (unauthorized) insurer has not, and its policyholders are not protected by the guaranty fund.
| Term | Meaning |
|---|---|
| Admitted/authorized | Holds a certificate of authority; guaranty-fund protected |
| Non-admitted | No certificate of authority; no guaranty protection |
| Surplus lines | Non-admitted coverage placed only when admitted markets decline the risk |
Producers may place surplus-lines business with non-admitted insurers only for risks regular markets will not write, and through a licensed surplus-lines broker.
A policyholder of an ADMITTED (authorized) insurer that becomes insolvent is generally protected by:
NAIC Model Laws and the Producer's Role
The NAIC has no direct regulatory power; it develops model laws and regulations that states may adopt to promote uniformity (e.g., the Unfair Trade Practices Act, suitability and replacement models). Each state's legislature decides whether and how to adopt them.
McCarran-Ferguson (1945) confirmed that insurance is regulated by the states, exempting the business of insurance from most federal law to the extent a state regulates it. Federal law still reaches areas like securities (variable products) and ERISA.
Exam Tip: The NAIC writes models; states enact them. McCarran-Ferguson keeps insurance under state control but does not bar federal securities or ERISA oversight.
