By adopting green infrastructure in place of some gray infrastructure, Kansas City reduced the total costs of managing its combined sewer system through 2040 by over $2 billion.

Insurance markets don't become uninsurable overnight. The transition from insurable to uninsurable is the final stage of a sequence that can take years or decades to play out—a chain reaction of rising hazard exposure, accumulated losses, revised models, reinsurance repricing, shifting corporate strategies, and regulatory friction.
In an article we published this week on The Epicenter, we mapped the six-stage process through which a market becomes uninsurable. Understanding those stages can help regulators, investors, and policymakers understand which assets and regions might be approaching the same fate.
Insurers are not public utilities. They make strategic decisions about where to deploy capital based on scale, peril exposure, diversification, and regulatory conditions.
Once in a market, insurers manage portfolios of homes, but the profile of the overall portfolio matters far more than the characteristics of any individual property. A well-built, fire-resistant home can still be rejected by an insurer—not because there’s something uninsurable about that specific house, but because the insurer has no more room for that exposure type.
When losses force insurers to reassess their exposure, the trigger doesn't need to have occurred in the same market. A major wildfire event in New Mexico, for example, can prompt insurers to review their book and recognize they have clients with a similar risk profile in California.
A decline in profitability can trigger a reset. Modeling firms revise their risk estimates and release updated outputs. When those outputs show elevated exposure, insurers have to decide how to react. Smaller insurers, who rely more on third-party models than proprietary analyses, can be the first to make changes.
After evaluating the new risk data and potentially bearing higher reinsurance costs, insurers will reprice their premiums to reflect the new information. In heavily regulated states, that process can take years. Insurers facing inadequate prices have limited options: absorb losses, reduce exposure through nonrenewal, or exit.
As insurers exit or raise prices, a collective judgment forms. Those remaining face an escalation of the problem: The highest-risk policies accumulate on their books as more cautious competitors leave. As a result, profitability deteriorates further. The market doesn't collapse like a bank run. Instead, an insurer becomes progressively less willing to insure at prior terms until it is confident it can deliver on its shareholders’ expectations.
Understanding these six stages can help decision makers identify the next vulnerable market and work upstream. That means intervening before the risk gets locked in; first, at the pre-development stage. Then, by applying a resilient lens to construction—through defensible space, fire-resistant construction, and community-wide mitigation efforts.
Capital will follow demonstrable, measurable risk reduction. The markets that build that case early are the ones that will stay insurable.

The economic losses from disasters that are not covered by insurance continue to grow, but resilience projects are generating measurable positive returns.
If today’s funding landscape resembles disconnected wells, then climate resilience requires something closer to a watershed—where resources are intentionally pooled, directed, and circulated across geographies, sectors, and time horizons.
Climate resilience is often framed as a problem of insufficient funding. In reality, it is a problem of how funding is structured and deployed.
