States employ a variety of rate regulation mechanisms such as prior approval, modified prior approval, file and use, and use and file. The form filing laws govern the type of policy form regulation used by the state and may not require explicit approval by the state regulator prior to using the new rate. This analysis is based on when the rate filing is "disposed" by the state regulator and does not take into account when new rates became effective for new and renewal business. In some instances, the new rate was in effect prior to the particular month the filing has been "disposed" by the regulator.

GEICO Corp. could see the largest aggregate increase in private auto premiums from rate hikes approved in June, according to an S&P Global Market Intelligence analysis.

GEICO subsidiaries received regulatory approvals for 27 rate hikes across seven states during the month, which could boost the group's total premiums by $418.7 million. More than half of that increase is expected to come from Virginia, where regulators signed off on six increases altogether, with two of them making the list of the most impactful changes. Both new rates went into effect on June 16 for new business and have an expected implementation date of Aug. 14 for renewal business.
