Impact of Increasing Inflation on Personal and Commercial Auto Liability Insurance

This paper examines loss development trends in personal auto liability insurance, as well as updating prior research on commercial auto liability insurance. It extends previous work in attempting to use Annual Statement data through year-end 2022 aggregated from all U.S. insurers to determine the impact of inflation on selected property/casualty insurance lines of business. Prior research used data at earlier evaluation dates to focus on commercial auto liability and medical malpractice. Methodology and data are similar to prior approaches, as discussed in Appendix I.
