Wildfire season isn’t over, but 2026 has already produced $5.18 billion in catastrophe bonds tied to wildfire risk — nearly matching last year’s full-year record of $5.55 billion.
A catastrophe bond, or cat bond, is how an insurance company hands off a disaster it can’t afford to cover alone. The insurer sells a bond to investors. If the disaster defined in the contract doesn’t happen, investors collect a fat interest payment on top of their principal. If it does happen, the insurer keeps the principal and uses it to pay claims instead. It’s insurance, just wearing a bond wrapper.
Wildfire cat bonds barely existed as a category a few years ago — insurers and investors didn’t trust the models enough to price the risk. That changed as modeling firms got better at predicting where and how badly fires spread. Issuance has roughly doubled every two years since: $2.57 billion in 2023, $2.84 billion in 2024, $5.55 billion in 2025. The bigger driver isn’t just better math — wildfire losses are growing about 12% a year globally, faster than any other natural-disaster category, so insurers need somewhere to put risk they can no longer hold alone.
The scale of that risk showed up in January 2025, when wildfires in Los Angeles caused an estimated $40 billion in insured losses — the costliest wildfire event on record. Losses like that are exactly what cat bonds are built to absorb, spreading a single catastrophic event across capital markets instead of leaving one insurer to eat the whole bill.
The logic is the same one behind Gap Risk insurance and the Correlated Risk problem — someone has to hold the risk everyone else wants to avoid, and price it correctly. A cat bond doesn’t make wildfire risk disappear. It just moves it from an insurer’s balance sheet to whoever’s willing to hold it — for a price.
Not advice. Just how I see it.
