Conducting a study of credit history, credit-based insurance scores, and other rate factors in making rates for personal insurance.

HB 1748 requires Washington's Insurance Commissioner to study how insurers use credit history, credit-based insurance scores, and other rate factors when setting personal insurance premiums, particularly focusing on whether these practices disproportionately affect residents based on race, ethnicity, sex, socioeconomic status, or national origin. The study will collect data from insurers, analyze current practices and potential alternatives, and assess impacts on consumer costs and insurance availability. The Commissioner must submit a preliminary report by December 2025 and a final report by September 2026 with findings and policy options. This study does not change current insurance practices but aims to inform future legislative decisions about rate-setting factors. The bill expires December 31, 2033.
