McCarran-Ferguson Act
A 1945 federal law that gives individual states the primary authority to regulate the insurance industry rather than the federal government. This act allows states to tax and regulate insurance companies operating within their borders, creating the state-based insurance regulatory system still used today.
Example
“Due to the McCarran-Ferguson Act, auto insurance requirements vary significantly between states, with some requiring personal injury protection while others do not.”
Memory Tip
McCarran = 'My state CARries the responsibility' - it gave states the power to carry insurance regulation duties.
Why It Matters
This act is why insurance laws, requirements, and consumer protections vary dramatically between states, affecting everything from the coverage you're required to buy to the process for filing complaints. Understanding this helps explain why moving to a new state often means changing insurance requirements.
Common Misconception
Many consumers don't realize that insurance regulation is primarily handled by states rather than the federal government, leading to confusion about why insurance rules and availability differ so much across state lines.
In Practice
Because of the McCarran-Ferguson Act, a driver moving from Michigan (which requires unlimited personal injury protection) to Florida (which requires only $10,000 in PIP coverage) must completely restructure their auto insurance. The Michigan requirements could cost $2,000 annually while Florida's minimum might cost only $800, but with significantly different protection levels - all because states have regulatory authority under this act.
Etymology
Named after its sponsors, Senator Pat McCarran of Nevada and Congressman Estes Kefauver of Tennessee (though commonly called McCarran-Ferguson). Enacted in 1945 in response to a Supreme Court case that threatened state insurance regulation.
