_{U.S. states employ a variety of rate regulation mechanisms, including prior approval, modified prior approval, file and use as well as use and file. Some states do not require explicit regulatory approval prior to insurers using new rates. This analysis is based on when rate filings are "disposed" by state regulators and does not take into account when those new rates became effective for new and renewal businesses. In some instances, a new rate may have been in effect prior to the month the regulator approved the filing.}

Rate hikes for the two largest private auto insurers in the U.S. are expected to increase their premiums by more than $1 billion, according to an S&P Global Market Intelligence analysis of rate filings approved during the third quarter of 2022.

Subsidiaries of the group received approval for 105 rate hikes, which is expected to increase the overall premiums by $1.57 billion. Nearly 15%, or $229.5 million, comes from three rate increases New York regulators approved.

State Farm Mutual Automobile Insurance Co. is expected to see the second-largest increase of $1.31 billion from 44 rate hikes across 22 states.

In addition, the top three rate hikes approved during the quarter all belonged to State Farm.
