The U.S. commercial lines insurance segments are being challenged by slower revenue growth, inflation-based claim uncertainty and less favorable loss reserve experience.
While commercial lines reported statutory underwriting profits in four of the last five years, net written premium (NWP) growth is likely to slow in 2023 to 6%–7% YoY, vs. 10% in 2022 and 15% in 2021.
U.S. Commercial Auto Insurance Premiums
Car insurance policies that major insurance companies underwrite tend to be less expensive. Because large insurers write millions of policies each year, they can afford to price their policies more competitively.
Additionally, the biggest insurance companies in the U.S. often have more coverage options. If you want to customize your policy with endorsements or need specialty coverage like rideshare insurance, a large provider is more likely to have those policies.
