What is the title of the head of a state insurance department that supervises the insurance business and administrates insurance laws?

The head of a state insurance department, responsible for overseeing the insurance business and administering insurance laws, is designated as the Commissioner. This title reflects the authority and responsibility these officials hold in regulating the insurance industry within their state, ensuring compliance with established laws and protecting consumers. The role often involves issuing licenses, conducting examinations of insurance companies, and enforcing regulations to maintain market integrity.

The other titles, while they may relate to aspects of insurance or underwriting, do not specifically denote the chief regulatory authority within a state insurance department, which is crucial for understanding the governance of insurance practices.
