The anchor piece in this series made a claim worth proving out: that Florida's property-tax amendment is a balance-sheet event for community banks, and that the funding side of the balance sheet is where it starts. This piece does the proving. The logic is a short chain. A government that collects less revenue is a government that holds less cash. The cash it holds sits in bank deposits. And community banks hold a share of those deposits far larger than their size would suggest. Follow that chain to its end and you arrive at a single ratio that tells the story: loans to deposits, climbing at the worst possible time.
Start With the Cash, Not the Tax
The headline number is the revenue loss. Statewide, the amendment is projected to reduce local government revenue by more than $8 billion a year, and the version on the ballot carries no state trust fund to replace it. What remains is constitutionally restricted to core public needs. A county or city facing that gap does not absorb it quietly. It draws down reserves, defers projects, and runs leaner operating balances. Every one of those moves is a reduction in the cash a government keeps on deposit.
That is the impact-to-action step that matters for a bank. The tax change is the impact. The deposit drawdown is the action. And because the revenue loss arrives over 2027 and beyond rather than all at once, the deposit erosion is gradual and quiet, which is precisely what makes it easy to miss until it shows up in the cost of funds.
Two Deposit Pools, Both Cheap, Both Exposed
The exposure concentrates in two of the lowest-cost, stickiest funding sources a community bank has.
Public and operating funds. In Florida, government deposits flow through the Qualified Public Depository framework under Chapter 280, where banks pledge collateral against public balances and share contingent liability. Credit unions were added to the program in 2024, so they share this exposure too, but banks still hold the bulk of public funds. These are large, relationship-driven, low-beta deposits, exactly the kind a bank builds a treasury-management franchise around. When local governments draw down operating cash to cover revenue shortfalls, those balances shrink first. Worse, a government under fiscal strain may consolidate banking relationships or chase yield it did not need when budgets were flush, so the risk is not just smaller balances but lost relationships.
Property-tax escrow. The second pool is easy to overlook. Servicers collect monthly escrow for taxes and insurance and hold it as non-interest-bearing deposits until disbursement. Cut the homestead tax and the tax portion of that escrow shrinks. But here is the nuance that keeps this honest: Florida's insurance crisis is pushing the insurance portion of escrow up by double digits, so the net effect is a composition shift, not a clean decline. Escrow may hold its dollar level while changing its makeup. And it only matters at all for banks that retain servicing in-house. For a bank that sells servicing or subservices, the escrow channel is close to a non-event.
Why Community Banks Hold the Exposure
This is the part that turns a statewide policy into an industry-specific risk. Community banks punch far above their weight in exactly the segments this touches. Nationally, banks under the community-bank threshold hold roughly 15 percent of all bank loans, yet they hold close to 30 percent of commercial real estate loans and 36 percent of small-business loans. The same local orientation that produces that lending concentration produces a deposit concentration: community banks chase local government, school district, utility, and operating relationships that national banks treat as too small to bother with. For a bank that has made public funds and local operating deposits a deliberate niche, these balances can be a meaningful double-digit share of total funding.
A national bank funds itself in national markets. A community bank funds itself out of the local economy, which means it funds itself, in part, out of the local government budget. That is the concentration the amendment puts in play.
A money-center bank with a national deposit base barely registers the loss of a few Florida municipal accounts. A single-market community bank with a public-funds franchise registers it on the cost-of-funds line within a couple of quarters.
Why It Matters: the Loan-to-Deposit Ratio Climbs
Here the funding story meets the timing trap. Lending pulls forward into 2026 as buyers rush to purchase and establish homestead before the residency clock starts in 2027. So loans grow in the good year. Then in 2027, as budgets reset, the low-cost public and operating deposits begin to erode. Loans up, cheap deposits down, and the loan-to-deposit ratio climbs into the gap.
A rising loan-to-deposit ratio is not an abstraction. It forces a bank toward costlier, more rate-sensitive funding, brokered deposits, higher CD rates, or wholesale borrowing, precisely as the easing cycle is already compressing net interest margins and making low-cost operating deposits the industry's contested battleground. The amendment does not create the margin problem. It pours fuel on it, draining the cheapest deposits at the moment they are hardest to replace. And a bank that has to fund a loan book with hot money has traded a structural advantage for a structural vulnerability.
What We Would Do Now
The funding problem is the most fixable of the series, but only with lead time. Every one of these is easier in 2026 than in 2027.
- Size it precisely. Quantify public and operating funds, and tax escrow net of rising insurance escrow, as a share of total funding, and tag the specific relationships and maturities.
- Stress the ratio. Model the loan-to-deposit ratio and liquidity under the phased steps and a full-elimination case, with honest deposit-drawdown timing and a clear view of replacement funding cost.
- Grow core funding ahead of the erosion. Lean into treasury-management relationships that throw off operating deposits beyond government, HOAs, title and escrow companies, medical and professional practices, the deposits least likely to leave for fifteen basis points.
- Use reciprocal deposit networks. Programs like ICS and CDARS let a bank retain large, rate-sensitive balances with extended FDIC coverage rather than lose them to a competitor, which also helps with the high-net-worth downsizer money discussed below.
- Pre-test contingent liquidity. Confirm and operationally test FHLB and Federal Reserve facility capacity now, with collateral schedules current, so a funding gap is a planned draw rather than a scramble.
- Reduce the public-funds concentration deliberately. The time to bring a concentration down is before it is tested. That can mean capping new public balances or diversifying the funding base, not abandoning a profitable niche.
Who Is Less Exposed, and Who Can Turn It to Advantage
The funding hit is concentrated, which means most of the market is not exposed, and some of it stands to gain. Knowing where you sit is half the strategy.
On the bank side:
- Large and national banks with no local muni concentration barely feel it, and they can compete harder for the deposits a stressed community bank is forced to chase.
- Banks whose public-funds franchise sits outside Florida carry the same business model with none of this specific exposure, and may look relatively stronger to acquirers and regulators.
- Banks that outsource or subservice escrow and never counted it as a funding source have no escrow runoff to manage at all.
- Well-capitalized banks that can price the risk may find opportunity in selectively taking public deposits that weaker competitors shed, if they are paid for the volatility and collateral cost.
- Banks positioned for the equity wave can offset deposit erosion on the household side. As the lock-in effect eases, long-tenured owners who sell and downsize realize large gains, and that money has to land somewhere. A bank with the deposit and wealth-management capability to capture it can replace eroding public funds with inbound household balances.
Beyond banking: the same downsizing wave that pressures one balance sheet feeds another. Title and closing firms see transaction volume, wealth managers see rollover assets, and the bank that partners with them is positioned at the front of that flow rather than the back.
In Brief
- Impact: more than $8 billion a year less in local revenue, with no state backfill. Action: governments draw down the operating and reserve balances they hold on deposit.
- Incidence: community banks hold a disproportionate share of local public and operating deposits, the same way they hold 30 percent of CRE and 36 percent of small-business loans on 15 percent of industry loans. National banks barely notice.
- Why it matters: loans pull forward into 2026, cheap deposits erode in 2027, and the loan-to-deposit ratio climbs into the gap, forcing costlier funding into an already compressing margin.
- Do now: size both deposit pools, stress the loan-to-deposit ratio, grow core treasury deposits, use reciprocal networks, pre-test contingent liquidity, and bring the public-funds concentration down deliberately.
- Less exposed or advantaged: banks with no local muni concentration, out-of-Florida public-funds franchises, escrow outsourcers, well-capitalized risk-pricers, and banks built to capture the downsizer equity and wealth inflows.
