State Regulation & McCarran-Ferguson
Key Takeaways
- McCarran-Ferguson (1945) confirms that insurance is regulated primarily by the states, with federal antitrust law applying only where state law does not.
- Each state's insurance department (Ohio's Superintendent) licenses insurers and producers, reviews rates and forms, oversees solvency, and polices market conduct.
- The NAIC is an organization of state regulators that drafts model laws and promotes uniformity but has no direct regulatory authority.
- Admitted insurers are licensed and regulated; surplus-lines insurers write declined risks through a broker after a diligent search and lack guaranty-fund protection.
Who Regulates Insurance
Insurance in the United States is regulated primarily by the states, not the federal government, a structure confirmed by the McCarran-Ferguson Act of 1945. After a 1944 Supreme Court decision held that insurance was interstate commerce subject to federal authority, Congress passed McCarran-Ferguson to return regulatory authority to the states, providing that federal antitrust and commerce laws apply to insurance only to the extent that state law does not regulate the activity. The exam tests that McCarran-Ferguson preserves state-based regulation of insurance.
The Role of the State Insurance Department
Each state has an insurance department headed by a commissioner, director, or superintendent (in Ohio, the Superintendent of Insurance, leading the Ohio Department of Insurance). The regulator's core functions, tested directly on the exam, include:
| Function | What the regulator does |
|---|---|
| Licensing | Licenses insurers and producers; can deny, suspend, revoke |
| Rate and form review | Reviews rates and policy forms for compliance |
| Solvency oversight | Monitors insurer financial condition; conducts examinations |
| Market conduct | Investigates unfair trade and claims practices |
| Consumer protection | Handles complaints; enforces the insurance code |
| Rulemaking and enforcement | Issues regulations; imposes fines and orders |
The NAIC
The National Association of Insurance Commissioners (NAIC) is not a regulator; it is an organization of the state insurance regulators that promotes uniformity by drafting model laws and regulations that states may adopt. The NAIC also maintains databases and accreditation standards that improve coordination among states. The exam tests that the NAIC has no direct regulatory authority and that regulation occurs at the state level, with the NAIC providing models and coordination.
Admitted vs. Surplus Lines
State regulation distinguishes admitted (authorized) insurers, which hold a certificate of authority and whose rates, forms, and solvency the state regulates, from non-admitted (surplus lines) insurers, which are not licensed in the state and may write only risks that admitted markets decline, through a licensed surplus-lines broker who must perform a diligent search of the admitted market first. Surplus-lines policies are generally not protected by the state guaranty fund. The exam tests the surplus-lines diligent-search requirement and the loss of guaranty-fund protection.
Why This Framework Matters
Understanding that insurance is state-regulated under McCarran-Ferguson, that each state's department (Ohio's Superintendent) licenses, reviews rates and forms, oversees solvency, and polices market conduct, and that the NAIC provides models without regulating, gives you the framework for both the national regulation questions and the Ohio regulation chapter, where these national concepts attach to specific Ohio statutes, the Superintendent's powers, and Ohio's licensing and consumer-protection rules.
When a national regulation question asks who regulates insurance or what authority a state department holds, this state-primacy framework supplies the answer.
The McCarran-Ferguson Act established that insurance is primarily regulated by:

State Primacy and Its Players
Insurance is regulated primarily by the states, confirmed by the McCarran-Ferguson Act of 1945, which provides that federal antitrust and commerce laws apply to insurance only to the extent state law does not regulate the activity. Each state's insurance department, headed by a commissioner, director, or superintendent (in Ohio, the Superintendent of Insurance), licenses insurers and producers, reviews rates and forms, oversees solvency, polices market conduct, and protects consumers.
The NAIC is frequently confused with a regulator. It is an organization of the state regulators that drafts model laws and regulations and promotes uniformity and coordination, but it has no direct regulatory authority; regulation occurs at the state level.
| Body | Role |
|---|---|
| State insurance department | Regulates insurers and producers |
| McCarran-Ferguson | Preserves state-based regulation |
| NAIC | Drafts model laws; no direct authority |
| Guaranty fund | Pays insolvent admitted insurers' claims |
State regulation also distinguishes admitted (authorized) insurers, which hold a certificate of authority and whose rates, forms, and solvency the state regulates, from non-admitted (surplus-lines) insurers, which write only declined risks through a licensed surplus-lines broker after a diligent search of the admitted market and whose policies are not protected by the guaranty fund.
When a question asks who regulates insurance, the answer is the states under McCarran-Ferguson; when it asks about the NAIC, recall its model-law role without authority; and when it concerns a hard-to-place risk, recall surplus lines through a broker after a diligent search, without guaranty protection.
Remember that insurance is regulated primarily by the states under McCarran-Ferguson, with federal antitrust law applying only where state law does not regulate, and that the NAIC is an organization of state regulators that drafts model laws but holds no direct regulatory authority. State regulation distinguishes admitted insurers (licensed; rates, forms, and solvency regulated) from non-admitted surplus-lines insurers (writing declined risks through a licensed broker after a diligent search, without guaranty-fund protection).
A scenario asking who regulates insurance, or what authority the NAIC holds, is testing this state-primacy framework.
A frequent regulation distractor casts the NAIC or the federal government as the primary regulator; the correct answer reflects that the states regulate insurance under McCarran-Ferguson and that the NAIC only drafts model laws and coordinates, so any option granting the NAIC binding authority over rates, licensing, or solvency is wrong by definition.
