Motor vehicle insurance covering damage, liability, and other risks is required for all drivers, across the US, with a few exceptions.[1]
Costs for this driver necessity been climbing since 2020, in part due to inflation driving up repair and part costs; between June 2023 and 2024, the price of personal motor vehicle insurance rose 19.5%.
Additionally, motor vehicle insurers may be raising the cost of insurance due to rising repair costs and lower returns from insurers’ bonds.
Insurance costs are rising faster than general inflation. The May 2024 Consumer Price Index data indicated that the motor vehicle insurance index — the change in insurance cost over time — was approximately 2.7 times higher than the nationwide inflation rate.
From 2020 to 2024, insurance rates rose by about 54%.
Several factors influence the cost of car insurance[2]:
Broader economic and regulatory environments also shape auto insurance rates.
According to the Congressional Research Service, rising inflation has increased repair and part costs, directly affecting premiums. The inflation spikes in 2021 (7%) and 2022 (6.5%) led to higher prices for building materials and auto repairs, directly influencing insurance rates.
Fluctuations in interest rates also impact insurers' investment returns, crucial for their profitability and pricing strategies.
When the Federal Reserve spiked interest rates in 2022, there was a notable decrease in the value of insurers' bond investments, impacting their overall financial stability.
With less income from insurer’ bonds and higher overall repair costs, insurance companies might raise the price of existing policies to offset this loss in revenue.
State-specific regulations can affect rates. Complex regulatory frameworks can delay or moderate rate increases, whereas states with more flexible regulatory environments allow insurers to adjust rates swiftly in response to market changes.
These factors collectively shape the complex dynamics of insurance pricing, balancing consumer protection and market stability.
