American Economy Insurance Company, an entity within the Liberty Mutual, has filed with Utah regulators for a 4% overall rate change (against a 9.2% indicated need) across its Personal Automobile program.

The adjustment is designed to update base rates by coverage line—including bodily injury, property damage, and collision—to preserve rate adequacy while maintaining affordability.

The filing influences 23,806 policyholders and $63.6 million in written premiums. The company relied on industrywide trend data to justify the modest adjustment and submitted via the SERFF electronic filing pipeline.

The insurer, domiciled in Indiana, last revised rates on July 8, 2025, with a neutral impact.

Filing submitted February 3, 2026; new business effective March 10, 2026; renewals effective April 19, 2026.
