State Farm, the largest home insurer in California, is asking for an emergency rate hike from state regulators as it warns that multibillion-dollar payouts from the Los Angeles wildfires threaten its balance sheet and the broader insurance market.

State Farm wrote in a letter on Monday that the recent fires in Los Angeles threaten its finances and are “the costliest in the history of the company.”

State Farm, which already has rate increase requests pending, asked state officials to approve more insurance price increases.
