The Deposit Franchise: Why Your Checking Account Is a Bank's Most Valuable Asset

Ask most people what a bank does and they'll describe lending. Ask a bank executive what determines their institution's value and you'll hear about deposits — specifically, about how slowly those deposits reprice when market rates move. A checking account paying almost nothing, held by a customer who won't leave, is among the most valuable assets in banking, and the industry has a term for the aggregate: the deposit franchise. Research on the recent rate cycle estimated that franchise value rose from roughly zero percent of bank assets before the hikes to around 11% at the peak — enough to offset the losses those same hikes inflicted on bank asset portfolios. Then, at a handful of institutions, it ran out the door. This report examines what deposits are actually worth, to whom, and why.

The core thesis

Our rate transmission analysis documented an asymmetry that puzzles most consumers: when policy rates rise, borrowing costs follow quickly while deposit rates crawl. This report explains the mechanism behind that asymmetry, and the explanation is more interesting than "banks are greedy" — it is that a deposit's value to a bank is inversely related to how much the bank has to pay for it, and the whole business is organized around keeping that number low.

The thesis has three parts. First, the deposit franchise is a genuine economic asset, not an accounting artifact: the ability to fund assets at rates well below market, persistently, is worth a great deal, and it fluctuates with the rate environment in ways that materially affect what a bank is worth. Second, it is built on customer inertia and convenience — direct deposit, bill pay, branch access, and the friction of switching — which means the franchise is fundamentally a relationship business wearing a balance sheet costume. Third, and most consequentially, the same properties that make a franchise valuable can make it fragile. A deposit paying far below market is valuable precisely because the depositor isn't optimizing; if something causes them to start optimizing, the value evaporates at whatever speed they can move money — which, in a world of instant transfers and mobile banking, is now very fast indeed.

For the household on the other side of the ledger, the practical translation is blunt: the gap between what a large branch bank pays and what a competitive account pays is the price of convenience, charged in foregone interest, and it's one of the few costs in consumer finance that can be eliminated entirely with an afternoon's effort.

A deposit is worth more to a bank the less it costs them. Everything about how deposits are priced, marketed, and defended follows from that one sentence.

Deposit beta, explained

Deposit beta is the share of a market rate change that a bank passes through to depositors. If the policy rate rises two points and a bank raises its savings rate half a point, that's a beta of roughly 0.25. A beta of 1.0 means full pass-through; a beta near zero means the deposit costs the bank essentially the same regardless of what happens to rates.

Why it matters so much: a bank's assets reprice upward with rates while low-beta deposits don't. The spread widens, and the widening is pure margin. A large retail bank funding itself with checking accounts at a beta near zero, while its loan book and securities yield more, is earning the difference on every dollar — and that difference grows as rates rise.

Betas vary systematically, and the pattern is well documented:

• Transaction accounts — checking, basic savings — have the lowest betas. They're held for access, not yield.
• Time deposits and CDs have high betas, since customers explicitly shop them on rate.
• Branch-dense banks have lower betas than those relying on online platforms, because convenience and physical relationship substitute for yield.
• Insured retail deposits have lower betas than uninsured ones, since large depositors are more sophisticated and more rate-sensitive.
• Large banks pay less than small ones for comparable deposits, generally attributed to superior liquidity and ancillary services rather than to market power alone.

Research on the recent cycle found something important about how betas rose: the increase came primarily from changes within deposit categories rather than customers shifting from checking into CDs. People didn't mostly move their money into higher-yielding products — banks had to pay more for the same products, because the alternative had become visible.

What the franchise is worth

Aggregate the beta advantage across a bank's deposit base, capitalize it, and you get deposit franchise value: the present value of funding at below-market rates. Work on the recent rate cycle estimated this rose from roughly 0% of assets in 2021, before the hikes, to about 11% at the peak — an enormous swing.

That number does two things at once. It explains why bank equity held up reasonably well through a period when rising rates inflicted large mark-to-market losses on bank bond portfolios: the same research estimated asset values fell roughly 8%, meaning banks were approximately hedged, with the gain on the deposit franchise offsetting the loss on assets. And it reframes what a bank is. An institution whose deposit franchise is worth 11% of assets is, in substantial part, a business that owns a relationship with depositors — the lending is what it does with the funding, not the source of its edge.

Three implications follow for anyone reading bank strategy. Deposit gathering is defended more fiercely than loan growth, because the franchise is the moat. Branch networks persist past the point transaction economics justify them, because they suppress beta. And account features that increase stickiness — direct deposit, bill pay, autopay linkages, and the switching friction our account guidance describes — are worth more than their direct revenue, because each one lowers the probability the deposit leaves when rates rise.

Insured, uninsured, and the 43% question

Deposit insurance covers balances up to a limit per depositor per institution, and the share of deposits above that line is one of the most-watched numbers in banking.

Federal Reserve Bank of St. Louis analysis put the ratio of uninsured to total deposits at US commercial banks at about 43.3% at the end of 2025. The path there is informative: it reached a twenty-year peak around 47.4% in late 2021 as pandemic-era stimulus and rate-driven deposit attractiveness swelled balances, declined to roughly 40.7% by mid-2024 following the 2023 banking turmoil, and has since risen back to almost exactly its pre-pandemic level — the same 43.3% recorded at the end of 2019 — with the largest banks accounting for most of the recent increase.

The composition matters because insured and uninsured deposits behave differently under stress in a way that has nothing to do with rate sensitivity. An insured depositor has no reason to run: their money is protected regardless of what happens to the institution. An uninsured depositor has every reason to, and the incentive strengthens precisely as the bank's condition weakens. Research modeling this finds that demand for uninsured deposits declines with a bank's financial distress while demand for insured deposits does not — which is the formal statement of an intuitive point.

The runnable franchise

Here is the finding that reframes the 2023 episode, and it is more specific than the popular account.

The dangerous combination was not simply "a lot of uninsured deposits." It was uninsured deposits with low betas — accounts paying well below market that were also unprotected. Research on the period found that banks with more uninsured deposits saw lower stock returns around the failures, but only if those uninsured deposits had low betas. A bank with substantial uninsured deposits that paid close to market rates was not exposed in the same way, because there was no franchise value in those deposits to lose.

The mechanism, once stated, is clean. A low-beta uninsured deposit is one where the customer is leaving money on the table and bearing risk. That customer has two independent reasons to move — yield and safety — and the moment either becomes salient, both do. When they leave, the bank loses not just funding but the franchise value that had been offsetting its asset losses. The hedge disappears exactly when it's needed, which is what distinguishes a deposit franchise run from a classic liquidity run.

Two broader observations follow. Franchise value is a valuation of customer inertia, and inertia is not a contract. Its persistence is an empirical regularity that holds until it doesn't, and the conditions that break it — rate gaps becoming visible, safety becoming salient — can arrive together. And the same digital infrastructure that improved consumer access accelerated the failure mode: money that once moved at the speed of a branch visit now moves at the speed of a mobile app, a dynamic our instant payments analysis examines from the settlement side.

What online banking changed

The structural trend beneath all of this is that deposit betas have risen, and the increase concentrates where digital distribution has displaced branches. Research finds betas rose significantly more for banks relying on uninsured deposits and for those with lower branch density, and attributes it to the greater rate sensitivity of customers who bank online.

The causal story is simple and probably irreversible. When comparing rates required visiting institutions or reading newspaper tables, most people didn't. When it requires opening a browser tab, more do. When moving money required paperwork and days, most didn't. When it requires a few taps and settles quickly, more will. Every reduction in friction raises the effective beta of the entire system, which compresses the franchise value that low friction had been generating.

This is genuinely good for depositors and genuinely difficult for banks whose economics assumed the old friction. It also explains a set of behaviors that otherwise look irrational: aggressive promotional rates for new money paired with unchanged rates for existing balances, relationship pricing that rewards account consolidation, and the persistence of branch investment in a period of declining branch transactions. Each is an attempt to hold beta down as the environment pushes it up.

The competition for primacy

Because franchise value depends on stickiness rather than balance alone, the strategic objective is primacy — being the account where the paycheck lands and the bills are paid, rather than one of several accounts a customer holds.

Primary accounts have systematically lower betas, because they're held for function rather than yield. They also generate the ancillary economics that make a low-yield deposit worthwhile for the customer: bill pay, card usage and the interchange it produces, overdraft revenue where applicable, and the data that supports cross-selling. The competitive tools are correspondingly specific — direct deposit incentives, early access to direct deposit funds, fee waivers conditioned on deposit activity, and relationship pricing tiers.

Two consequences worth naming. The unbanked and underbanked population is a strategic target for exactly this reason, since acquiring a primary relationship early is worth more than acquiring a balance later — which is part of why fee-free account availability has expanded, as our unbanked analysis notes, and a reminder that the improvement was competitive as much as charitable. And the account screening system becomes economically significant: an institution that excludes a customer through the databases our specialty reporting report describes is declining a primary relationship, which is a larger cost than the overdraft risk being avoided in many cases.

What it means for the account holder

Translate all of this to the household side and a few things become actionable.

The rate gap is real money and it is entirely within your control. The difference between a large branch bank's savings rate and a competitive account's is the deposit franchise, viewed from the paying side. On a meaningful balance held over years, moving it is one of the highest hourly-return financial actions available — and unlike most such actions, it requires no ongoing effort after the transfer.

Convenience has a price, and it's fine to pay it knowingly. A household that values branch access, or that keeps its operating balance where its bills are paid, is making a reasonable trade. The problem is paying it unknowingly on balances that don't need to be there — which is why the practical structure most advisors converge on is a transactional account wherever it's convenient and a separate higher-yield account for reserves.

Insurance limits are worth understanding if balances are large, including how coverage works across ownership categories and institutions.

And the buffer argument gets stronger, not weaker, in this light. The reserve our savings analysis identifies as the most protective household asset is also the balance most worth placing where it earns something — because it's the money you're least likely to touch, which is precisely the money a low-beta account is least likely to reward you for holding.

Scenarios and what we're watching

Scenario	Shape of the world	Signposts
Base case — grinding beta compression	Digital distribution continues raising rate sensitivity; franchise values compress gradually; competition for primary relationships intensifies	Deposit betas by institution type; branch counts; primary account acquisition offers
Stability case — the franchise holds	Inertia proves more durable than expected; large banks retain low-beta bases; consolidation of deposits toward the largest institutions continues	Deposit share by bank size; uninsured ratio trend; rate spread between large and online banks
Fragility case	A rate or credit shock makes both yield and safety salient simultaneously at institutions with low-beta uninsured bases; funding moves at digital speed	Uninsured deposit concentration; unrealized asset losses; deposit outflow velocity

What we're watching: the uninsured deposit ratio and its concentration by institution, which is the clearest single fragility indicator; deposit beta trends, particularly whether digital distribution continues pushing them up through the next cycle; the rate spread between large branch banks and competitive accounts, which measures the franchise from the household side and determines how much is being left on the table nationally; and primary relationship competition, where the most interesting product innovation in retail banking is currently happening for entirely self-interested reasons.

The deposit franchise is the least visible major asset in American finance. It sits on the liability side of the balance sheet, it belongs to customers who mostly don't know they're funding it, and its value is a measure of how little attention they're paying.
