1.6 Insurance Regulation

Insurance Regulation at the State Level​

Historically, the regulation of insurance in the United States was primarily controlled by individual states, and the insurance industry was generally not subject to certain federal commerce laws. This changed when the United States Supreme Court ruled that insurance transactions constituted interstate commerce, making the insurance industry subject to federal regulation.

In response, Congress enacted the McCarran-Ferguson Act, also known as Public Law 15, in 1945. This law established that the regulation of insurance is in the public interest and should remain primarily under the authority of the states. The Act also provides that the insurance industry is exempt from certain federal antitrust laws to the extent that insurance activities are regulated by state law. This framework helps avoid unnecessary overlap and excessive regulation between state and federal governments.

State regulation of the insurance industry is carried out through the legislative, judicial, and executive branches of government. Each branch plays a distinct role in the development, interpretation, and enforcement of insurance laws.

  • The legislative branch creates and enacts insurance laws, known as statutes, that are designed to regulate the insurance industry and protect consumers.
  • The judicial branch interprets insurance laws and determines whether those laws comply with constitutional requirements.
  • The executive branch is responsible for administering and enforcing insurance statutes and regulations within the state.

Each state appoints or elects a Commissioner, Director, or Superintendent of Insurance to oversee the regulation of the insurance industry within the state. This official represents the executive branch of state government and is responsible for administering and enforcing state insurance laws. The insurance regulator also has the authority to issue rules and regulations that help implement and enforce the state's insurance statutes.

Regulatory Support Organizations​

National Association of Insurance Commissioners (NAIC)​

The National Association of Insurance Commissioners (NAIC) is a regulatory support organization made up of the chief insurance regulators from all fifty states, the District of Columbia, and five U.S. territories. The organization is created and governed by these state insurance regulators to assist with the regulation of the insurance industry.

The NAIC provides research, educational resources, model laws, regulatory guidance, legislative recommendations, and interpretations to support state insurance departments. State regulators may choose whether to adopt or reject the NAIC's recommendations. Although the NAIC does not have the legal authority to create or enforce insurance laws, one of its primary objectives is to encourage greater uniformity and consistency in insurance regulation among the states.

Insurance Services Office (ISO)​

The Insurance Services Office (ISO) develops standardized insurance policy forms and provides industry research, statistical data, and underwriting information for insurers. Insurance companies may use ISO's forms, research, and documented data as a foundation for developing insurance coverages, underwriting guidelines, and rating practices.
