A new wildfire season looms on the horizon across the United States, and as the last two years of huge wildfire insured losses and extensive devastation to lives and property clearly illustrates, wildfire is no longer an easily manageable loss for the (re)insurance industry – but a new peak peril.
So, what could be in store for the 2019 season? The industry is reeling from back-to-back seasons with losses over US$10 billion. This is unprecedented even during a period when average losses between 2011-2018 were at US$3.7 billion. And looking back, this is up 40x compared to 1964-1990, where losses were below US$100 million in today’s prices. What is changing with this peril, what are the risk drivers that we need to look out for?
What will the 2019 wildfire season bring across the United States?
Across the United States, around eight and a half million acres burned in 2018, nearly three times the annual average during the 1980s and 1990s. That is the equivalent of the entire state of Maryland burning in one year. Last year’s Camp and Woolsey fires in California burned a total of 245,000 acres – these two fires alone burnt a combined area around three times the size of Detroit, destroyed more than 12,000 structures and killed 80 people.
It is getting hard to argue that the size and ferocity of the most recent wildfires across the U.S. are just anomalies, the evidence just does not support these events as being exceptional anymore.
As California’s then Governor Jerry Brown stated at a press conference as the Camp and Woolsey fires raged, these wildfire events are “… the new abnormal …” and that events may worsen over the next few decades. He added that “… the best science is telling us that dryness, warmth, drought, all those things, they’re going to intensify.”
