Insurance retreat triggers a climate repricing of housing in a G7 economy

The reading
Insured natural-catastrophe losses hit $137B in 2024 and the January 2025 LA fires added ~$40B more, while California's insurer-of-last-resort exposure has swollen past $500B. Insurance is how climate risk becomes a price; when the price becomes unpayable or unavailable, mortgage markets — and then home values — do the repricing insurers no longer will.
What would prove this wrong
This projection is WRONG if through 2030, no major metro area experiences sustained 15%+ home-value declines attributable to insurance withdrawal, and state backstop plans (FAIR/Citizens) shrink rather than grow.
Trigger events tracked
- A mega-catastrophe (major hurricane into Miami/Tampa, urban firestorm) exhausting a state backstop plan
- Reinsurance repricing pushing primary insurers out of additional states (the 2023 California template)
- Mortgage lenders declining originations on effectively uninsurable properties
- A state backstop requiring a taxpayer bailout, making the hidden subsidy explicit
