California Wildfires: Municipal Bond Investors Can Make a Difference

Natural disasters such as the LA wildfires affect communities both immediately and over time. Current estimates suggest that over $70 billion in municipal credits are exposed to these events, with overall economic losses estimated to be as high as $275 billion. Recovery for low-income communities can be especially hard.

Los Angeles will rebuild, but what will that look like for under-resourced communities, and how can impact investors help?

Conditions Ripe for Catastrophe

The exact causes of the fires in Southern California are under investigation, but “weather whiplash”—extreme shifts between unusually wet and exceptionally dry seasons—contributed to the fires’ rapid spread and intensity. Weather whiplash has increased globally by 31% to 66% since the mid-20th century. Such conditions lead first to rapid vegetative growth, then to the drying of vegetation, making an area highly vulnerable to fires. Combined with high winds—above 100 mph—and densely packed housing, weather whiplash creates a recipe for fast-moving fires in the wildland-urban interface.

Compounding the disaster, trees and vegetation—once incinerated—no longer anchor hillsides, raising the odds of landslides and flash floods that could damage surviving structures and impair water quality. These could further aggravate income inequalities and increase the risk of future catastrophes.

How Impact Investors Can Help: Mitigating wildfire risk requires improved forest-management practices, such as prescribed fires and forest thinning. Investing in city and county governments responsible for erosion-control structures, drainage systems and monitoring technology is crucial, in our view. Additionally, investing in water utility companies that prioritize reducing wildfire risk and subsequent flash floods may be more cost-effective than repairing damaged infrastructure and treating polluted watersheds.

Rising Costs of Insurance and Rebuilding

According to Cal Fire, at least 12,300 structures have been destroyed. To streamline rebuilding, Governor Newsom and Mayor Bass have issued executive orders to temporarily suspend the California Environmental Quality Act and the California Coastal Act; expedited the building-permit review process; directed state agencies to identify permit requirements and building codes that can be safely suspended or made more affordable; and created task forces focused on debris removal and watershed hazards.
