Insurance as Economic Infrastructure

For most of the modern era, property insurance was a quiet utility: available, affordable, and assumed. In catastrophe-exposed markets, that assumption has broken. Insurance is now the variable that decides whether places remain financeable at all.

California is the clearest case. As private carriers limited or withdrew coverage in wildfire-exposed areas, enrollment in the state's insurer of last resort — the FAIR Plan — surged, nearly doubling its policy count between September 2023 and June 2025. After the early-2025 Los Angeles wildfires, the FAIR Plan imposed a roughly one-billion-dollar assessment on private insurers to remain solvent — the first assessment of its kind — a cost carriers are permitted to pass through to their own policyholders.

Florida shows the same force running the other way. Following 2022 legal reforms that curtailed insurance litigation, its state-backed Citizens plan began shedding policyholders and the private market started to stabilize. Two opposite trajectories, one lesson: the availability and price of insurance now governs whether a market functions.

The mechanism is not abstract. A mortgage requires insurance; without coverage there is no lending, and without lending there is no development. When carriers retreat, the effect ripples straight into real-estate values, construction, and public revenue — not eventually, but immediately.

Regulators are responding by changing the rules of pricing itself. California's Sustainable Insurance Strategy now permits insurers to use forward-looking catastrophe models in rate-setting and asks them, in return, to write more coverage in high-risk zones — an acknowledgment that risk must be measurable and priced for a market to clear. The Insurance Information Institute has tracked the same repricing across catastrophe-exposed states.

Globally, the Swiss Re Institute has documented a persistent protection gap — the share of catastrophe losses that carry no insurance at all — that widens as exposure outruns coverage. The gap is where economic damage becomes permanent, because uninsured loss is loss that no balance sheet is standing behind.

There is a hard limit worth stating plainly. Where risk is genuinely uninsurable, no amount of clever structuring makes it otherwise. Early involvement by insurers and brokers can design risk down — siting, materials, mitigation, resilience — but it cannot manufacture insurability where the underlying hazard is simply too great. Honesty about that boundary is part of the discipline.

Within the boundary, though, sequence is everything. Insurers and their brokers see risk across thousands of comparable situations. Brought in at the end, they can only price what others have already built. Brought in at the beginning, they help shape an initiative so that it is more resilient by construction — and therefore financeable at all.

That is the shift this piece is about: insurance not as a cost applied to a finished plan, but as economic infrastructure that determines which plans are possible.
