Which of the following is not a duty of the California Insurance Commissioner?

The role of the California Insurance Commissioner encompasses a variety of responsibilities aimed at regulating the insurance industry within the state. Among these duties, enforcing Insurance Code regulations, revoking licenses as a disciplinary measure, and investigating insurance complaints are all essential functions directly associated with ensuring compliance and protecting consumers.

Setting insurance rates, however, is not typically a duty of the Insurance Commissioner in California. While the Commissioner does have the authority to review and approve rate adjustments in certain circumstances, the setting of rates is primarily driven by the insurance companies themselves, based on their actuarial analyses and market competition. Thus, while the Commissioner may regulate the process and ensure fairness, they do not actively set the rates, which distinguishes this option from the other duties listed. Understanding this function clarifies the distinction between regulatory oversight and operational autonomy within the insurance market.
