Drive two hours outside any major American city and the signs are hard to miss. Storefronts with hand-painted “closed” signs that have been up for years. Courthouses that smell like mildew. Town budgets assembled in a conference room by three people who also hold other jobs. These are not metaphors for decline. They are the actual administrative machinery of places that are running out of residents, revenue, and road. And increasingly, they are showing up — slowly, stubbornly — on the balance sheets of institutions that once considered municipal debt the safest thing they owned.
The 2020 U.S. Census revealed that 76% of the roughly 19,500 incorporated cities and towns in this country have fewer than 5,000 people. Most of them are rural. Most of them lack the industrial or commercial base needed to sustain local government through anything more than moderate stress. When things go wrong — a plant closes, a major employer leaves, a lawsuit produces a judgment that overwhelms the reserve fund — there’s simply not enough left to absorb the damage. Municipalities that have been pushed to the brink of bankruptcy generally experienced one or both of two types of fiscal problems: a large one-time financial hit that cannot be absorbed by the budget, or a structural operating deficit that continues long enough to burn through reserves entirely. In small towns, both of those conditions tend to arrive together.
Studies of the local governments that entered bankruptcy or receivership between 2008 and 2013 found that widespread poverty was a consistent theme, and the bankruptcies also tended to follow significant depopulation — half of those cities and towns had more than a quarter fewer residents than they had fifty years earlier. That pattern hasn’t changed. What has changed is the broader financial environment surrounding these towns, and that’s where it gets interesting for anyone holding a muni bond fund in a taxable account.
Some cities are losing 6% of their taxpayers annually. Services are being cut. Crime is increasing. Meanwhile, the revenue streams those municipalities pledged against their bond debt — property taxes, sales taxes, utility fees — are quietly eroding. The math eventually stops working. And when it does, the paper those towns issued doesn’t disappear. It migrates. It ends up in ETFs, in insurance company portfolios, in the fixed income sleeves of retirement accounts managed by people who live nowhere near the town that issued it.
External events — like the bankruptcy of a major employer, a natural hazard, or the closure of a retail anchor — can have dramatic effects on the financial stability of nearby populations and governments, with over 100,000 individual bond securities potentially exposed to geographically defined corporate failures. The Bed Bath & Beyond closures were an instructive case. When a single retailer shuttered hundreds of locations, analysts had to map which municipalities had built their revenue projections around that commercial activity. It’s a reminder that Wall Street’s exposure to small-town fiscal health isn’t hypothetical. It runs through every strip mall anchor and every property assessment.
Business bankruptcy filings in Q3 2025 hit 24,039 — the highest quarterly total since 2016. Most of the attention goes to corporate restructurings, to retailers and real estate entities filing Chapter 11. But the quieter story is what happens downstream when small businesses disappear from a town that depended on them. Less sales tax. Lower assessed commercial values. A thinner budget. More pressure on bonds already stretched thin. A K-shaped economy, where spending by lower- and middle-income consumers is increasingly strained, is among the key trends likely to generate another modest increase in bankruptcy filings in 2026. For small towns already operating on margins, that strain doesn’t stay abstract for long.
The takeaway from recent analysis is that munis carry real credit risk that the pre-2020 consensus chronically underpriced — a point that some advisors are finally saying out loud. For decades, the assumption was that municipal debt was nearly inviolable. Governments don’t go bankrupt, the thinking went. Except they do. And when they do, the process is slow, grinding, and deeply political. Municipal defaults and bankruptcies tend to lag recessions or times of economic stress — filings remain rare, but activity has picked up, with the City of Cle Elum in Washington state filing Chapter 9 in 2025 following a court judgment that exceeded what the city could absorb.
Since January 2025, at least 20 of the nation’s 25 most populous cities have reported budget gaps for fiscal year 2026, with Chicago, Los Angeles, San Francisco, and Washington all experiencing credit rating downgrades in a five-month span. If cities of that size and political visibility are struggling, it’s worth thinking hard about what’s happening further down the ladder — in the Fairfields and Cle Elums, in places where there’s no bond counsel on retainer and no emergency credit facility waiting. Even Denver’s rainy day fund has fallen below its own 15% target as the city leaned on reserves to cover operating expenses, and Denver is not a struggling Rust Belt town. It’s a prosperous, growing city. The vulnerability runs deeper than people want to admit.
There’s a feeling that Wall Street won’t reckon with this fully until it has to. That’s not cynicism. That’s history. The muni bond market has absorbed a lot of quiet stress over many years, and the rating agencies have generally been reluctant to mark things down until the filing is imminent. For now, most investors are being told that disciplined credit analysis and active management can navigate the risk. Maybe that’s right. But it’s worth remembering that the bonds funding a small town’s water system, or its school district’s capital program, were issued by people who also believed the worst-case scenario was someone else’s problem. Eventually, someone has to be holding them when the math stops working.
