When Insurers Walk Away: How Dropped Coverage Weakens Local Economies

Takeaway: When intensifying climate disasters lead insurers to drop homeowners' policies rather than raise prices, standard mortgage rules can trigger a cascade of "technical defaults," driving up foreclosures, depressing home values, and weakening local economies.
Key Points
The Insurance-Mortgage Link: Mortgages require hazard insurance. When insurers refuse to renew policies, homeowners who cannot secure expensive replacement coverage risk technical default and foreclosure, even if they can afford their monthly mortgage payments.
Severe Economic Spillovers: Higher non-renewal rates lead to measurable drops in local housing values—falling 16.5% for entry-level homes per one-percentage-point increase in non-renewals—as well as lower retail sales and reduced homeownership.
Policy Bottlenecks Matter: Non-renewals and foreclosures are significantly worse in states with strict premium price controls, fewer private insurers, no state-backed "insurer of last resort," and in socially vulnerable communities.
Why is homeowners insurance suddenly so difficult to keep? Across coastal states, wildfire-prone areas, and regions hit by severe storms, millions of Americans are opening the mail to find cancellation notices rather than higher bills. While rising premiums strain household budgets, being dropped entirely presents a far more dangerous dilemma.
Because almost all mortgage contracts require borrowers to maintain property hazard insurance, losing coverage puts a homeowner in immediate breach of their loan agreement. If a family cannot find an alternative policy in a shrinking market, the mortgage servicer may step in with costly "force-placed" insurance or initiate foreclosure.
To understand the broader economic fallout of this trend, economists Mary Brooke Billings, Stephen G. Ryan, and Han Yan investigated how insurance non-renewals ripple through local communities. Using a newly available national dataset from the U.S. Senate Budget Committee covering 23 major insurers (representing roughly 65% of the market) from 2018 to 2023, the researchers tracked policy non-renewals alongside data on climate damages, foreclosure filings, home values, retail sales, and homeownership across thousands of U.S. counties.
Findings
The researchers found that recent climate disasters—both within a county and across its broader state—consistently lead insurers to cut back coverage. This reaction is especially pronounced in states served by financially weaker insurers, states where regulatory rules require prior government approval for rate hikes, and areas facing volatile, hard-to-model climate risks.
When insurers decline to renew policies, the consequences for housing markets are swift. Using an instrumental variable strategy to establish cause and effect, the study shows that a one-standard-deviation increase in the county non-renewal rate leads to a 0.44 percentage-point increase in the foreclosure rate. Crucially, non-renewals trigger far more foreclosures than equivalent premium increases, proving that having coverage revoked is vastly more destabilizing to a household than facing higher prices.
These foreclosures, in turn, drag down the wider local economy:
Home Values Fall: A one-percentage-point rise in non-renewals reduces average single-family home prices by 8.3%, with bottom-tier (entry-level) homes dropping by 16.5%. Lower-income buyers often have fewer financial reserves to absorb insurance disruptions.
Consumer Spending Drops: Local retail sales fall by 8.6%, with durable goods (such as furniture, building materials, and appliances) suffering disproportionately when foreclosures force residents out.
Homeownership Shrinks: Non-renewals reduce local homeownership rates by 1.6 percentage points and decrease the total number of occupied homes in a county, indicating that displaced residents often leave the area altogether.
Context and Limitations
The study period (2018–2023) spans the COVID-19 pandemic, during which federal and state foreclosure moratoria temporarily dampened market distress. Consequently, the long-run effects in a post-pandemic environment could be even more pronounced. Additionally, outcomes vary widely depending on state legal structures: foreclosures rise faster in states with non-judicial foreclosure processes and in states without a Fair Access to Insurance Requirements (FAIR) plan acting as an insurer of last resort.
Why It Matters
For policymakers, well-intentioned efforts to cap insurance premiums can have unintended consequences. If regulations prevent insurers from pricing risk accurately, companies simply exit the market. When insurers leave, vulnerable households face mortgage distress, eroding local property wealth and tax bases. Protecting homeowners requires expanding residual insurance capacity, investing in climate-resilient infrastructure, and ensuring credit and insurance access remain viable as climate risks grow.

Economic Concept: Intensive vs. Extensive Margin
In economics, decisions typically adjust along two dimensions: how much of an activity occurs (the intensive margin) or whether it occurs at all (the extensive margin).
Consider an insurer responding to rising storm damages. Raising annual policy premiums from $1,500 to $2,000 is an adjustment on the intensive margin—the price changes, but the economic relationship continues, allowing the homeowner to adjust their monthly budget. Canceling the policy altogether or withdrawing from an entire state is an adjustment on the extensive margin—the transaction ceases entirely.
While markets can often absorb adjustments on the intensive margin, sudden breaks on the extensive margin can rupture interconnected contracts, such as mortgages, triggering severe ripple effects across the economy.
