RMS has produced estimates for the insured loss arising from the Thomas Fire that affected the Southern California counties of Ventura and Santa Barbara in December 2017. The estimate will fall between US$1 billion and US$2.5 billion, and includes loss caused by burn or smoke damage to personal, commercial, and industrial lines of business, along with insured loss from business interruption and additional living expenses. It excludes loss to automobile and agriculture lines of business and all damage related to the recent mudslides that impacted the same area. This estimate was calculated using RMS high-resolution exposure data and comparisons against historical fire damage, loss, and claim data.
As the Thomas Fire continues to climb the list of the top twenty largest California wildfires for both acres burned and structures destroyed, many in the insurance industry are asking how this fire, in addition to the other burned areas across Southern California, will impact their portfolio. A critical element in understanding the industry impact, but also the significance for an individual book, is the insured value of the burned structures. The Thomas Fire, which at 60 percent containment at the time of publication is already the second largest fire in California history with a reported burn area of 272,000 acres (110,074 hectares), has affected several different communities with wide ranges of average insured value.

Accompanied by a CAL FIRE escort, on Monday, October 23, RMS reconnaissance experts visited areas affected by the Wine Country wildfires, with a focus primarily on the Tubbs Fire which caused destruction across the Northern California counties of Napa, Sonoma, and Lake. Based on this reconnaissance, RMS has now updated its loss estimate, benefiting from an additional review of the available damage information, plus a review of historical fire damage data.
