Open Questions

The stakes

The American property insurance system is being tested by climate losses at a pace nobody priced for. When carriers fail, homeowners lose coverage, mortgages become non-conforming, and state guaranty funds — or, eventually, taxpayers — eat the difference. The Senate's December 2025 Demotech investigation isn't a one-off; it's the first visible crack in a wall most homeowners didn't know existed. The question of whether the insurers behind your policy can actually pay the claim is the most underappreciated risk in American homeownership.

What we're watching for

• IRIS ratio filings and state DOI quarterly reports — which carriers are breaching surplus thresholds
• Reinsurance pricing at mid-year and January renewals (capacity, layer pricing, retentions)
• Cat bond issuance volumes and pricing (Artemis, Lane Financial)
• Demotech rating actions and the unfolding Senate investigation
• Insurer insolvencies and state guaranty fund activations
• M&A signals — who's buying, who's exiting which markets

The stakes

Insurance is regulated state-by-state, which means the climate-insurance crisis is being fought fifty times in parallel — same dynamics, different politics, different speeds. California, Florida, Louisiana, North Carolina, and Texas are the front lines. New York and the Northeast are several years behind but heading the same direction. What states do now sets the template for how the federal government eventually responds. The next decade of American property insurance is being written in state capitols right now.

What we're watching for

• Department of Insurance market conduct exam orders and rate filings
• State legislative sessions — bills introduced, hearings, amendments, signings (Florida special sessions especially)
• Attorney general actions against carriers
• State residual market (Citizens-style) policy counts and assessment trajectories
• Pre-emption fights between state regulators and federal agencies
• Ballot initiatives on insurance reform

The stakes

If markets work, climate risk gets reflected in home values, mortgage rates, and insurance premiums quickly. If they don't, the gap between perceived and actual risk produces stranded assets, sudden corrections, and household balance-sheet wipeouts. The academic literature is still arguing about how fast this is happening and where. The answer matters for every homeowner deciding whether to buy or sell, every lender deciding whether to underwrite, every local government depending on property tax revenue.

What we're watching for

• Price-discovery papers from Bernstein, Keys, Kahn, Nolte, Gourevitch, and peers
• MLS analyses (Redfin, Zillow research) on flood-zone premiums and discounts
• GSE policy on accepted insurance ratings and climate disclosure requirements
• Mortgage denial rates and credit-spread differentials in high-risk geographies
• SEC climate disclosure rule implementation and corporate filings
• Methodology updates from Climate Central, First Street, ClimateCheck

The stakes

Managed retreat — buying out flood-prone homes and converting the land to open space — is the only adaptation tool that fully removes future climate loss exposure. It's also slow, expensive, politically fraught, and historically unequal. The programs that work tell us something about what's possible. The programs that fail tell us more. Most American homeowners don't know managed retreat is happening; the ones in eligible communities often have only weeks to decide what the rest of their lives will look like.

What we're watching for

• NJ Blue Acres acquisitions — Cranford, East Hanover, South Plainfield active; 1,200+ to date
• NY Resilient NY Program watershed studies and buyout grants ($250M in the 2024-25 state budget)
• North Carolina post-Helene buyout activity
• Long-term retreat case studies as they pass year-10+ (Princeville, Oakwood Beach, Soldiers Grove)
• Federal HMGP and BRIC grant awards for acquisition projects
• Equity critiques and the buyout-takeup gap in BIPOC and lower-income communities

The stakes

Behind every climate disaster is a complex financial backstop: private insurance, then state guaranty funds and residual markets, then the National Flood Insurance Program, then FEMA Individual Assistance, then SBA disaster loans, then nothing. Every major loss event tests this stack. Reform happens incrementally, almost always after a failure. Knowing who pays — and who falls through — is the difference between a recoverable household and a foreclosure. The middle-class American homeowner has been operating under assumptions about coverage that are no longer reliably true.

What we're watching for

• State guaranty fund activations and assessment patterns
• Citizens-style residual market policy counts and rate trajectories
• NFIP solvency, debt position, and reform legislation
• FEMA IA grant data and post-disaster supplemental appropriations
• SBA disaster loan approval rates and default trajectories
• Major class-action lawsuits and bad-faith claims litigation

The stakes

The “climate haven” narrative has been everywhere for a decade. The data is thinner than the narrative. If migration is happening at scale, it should show up in Census flows, MLS volume, IRS county-to-county moves, school enrollment patterns, and labor market data. So far the evidence is partial, regional, and slow-moving. Whether climate migration is the next major demographic event in American life or a journalist's projection still isn't settled — and the answer matters enormously for housing supply, fiscal policy, and where infrastructure investment should go in the next twenty years.

What we're watching for

• Census ACS migration data releases (annual)
• IRS Statistics of Income county-to-county migration data
• MLS volume and price data in alleged “climate haven” metros
• Academic work from Keenan, Hino, Pollack, Siders, and peers
• Tulsa, Vermont, and other migration-incentive program outcomes
• Insurance-driven migration evidence — people leaving Florida and California after non-renewals

The stakes

Federal action on climate and housing is slow, reversible, and easily ignored — until it isn't. The NFIP, the IRA's housing-energy provisions, FEMA's mitigation grants, the GSE policies on insurance, and the SEC's climate disclosure rules together form the federal architecture under American climate adaptation. Each can be expanded, weakened, or eliminated by Congress, the executive, or the courts. The implicit question under every administration is what survives. Homeowners depending on federal programs without understanding their political fragility are taking a risk they didn't know they signed up for.

What we're watching for

• NFIP reauthorization fights and Risk Rating 2.0 implementation
• IRA implementation — HEEHRA, weatherization rollouts, BRIC grant awards
• FEMA structural reforms and Administrator priorities
• GSE policy on accepted insurance ratings (the Fannie/Freddie/Demotech question)
• SEC climate disclosure rule status and litigation
• Federal supplemental disaster appropriations and OMB cost-benefit shifts

The stakes

Every story about insurance, retreat, federal aid, and adaptation has a distributional answer. Who gets coverage. Who gets bought out. Who gets the IRA tax credit. Who gets the FEMA grant. Who gets the legal help. American climate adaptation is unfolding on top of a housing market that already had massive racial, class, and tenure inequities baked in. The risk — and the early evidence — is that climate adaptation becomes another mechanism that reinforces those inequities rather than addressing them. This question runs through every other question on this page.

What we're watching for

• Distributional analyses of FEMA IA, NFIP payouts, and BRIC awards by race, income, and geography
• Renter vulnerability research — disasters disproportionately damage households without insurance options
• Mobile home park dynamics — most exposed housing stock, least insured, least protected by tenancy law
• Undocumented immigrant access to federal disaster assistance
• Environmental justice litigation and FEMA's Justice40 implementation
• Coverage of historically Black communities — Princeville, the Sea Islands, Gulf Coast communities
