Starbucks is not, technically, a bank. It doesn't take deposits, pay interest to customers, or answer to the FDIC. And yet the company is sitting on $1.5 to $1.9 billion in unspent balances loaded onto its app and prepaid cards at any given time, more cash than roughly 85 percent of U.S. commercial banks hold in total assets. More than 40 percent of its North American transactions run through that stored balance rather than a credit card swipe. That's not a coffee company quirk. That's a financial product, wearing a green apron.
The natural response to that stat is to treat it as a Starbucks-only phenomenon, a scale that only a company with 34 million loyalty members could pull off. That's the wrong lesson. The interesting part isn't the size of the number. It's that the mechanism behind it, a loyalty account that holds real money, is now something any retailer can plug into. You don't have to be Starbucks to build it.
What Starbucks actually built
The model is straightforward. Customers preload real dollars into an account; they spend down that balance in-store or in-app, and the company holds the float in between.
The money sits with the company until it's spent. The company gets to use those funds for operations and treasury yield while the balance sits.
A meaningful share of it never gets spent at all. Breakage, the unredeemed balance that gets recognized as revenue, has grown from $104.6 million in 2017 to $215 million in 2023, representing roughly 13 percent of all stored balances.
Members carrying a balance behave completely differently than members carrying only points. Starbucks Rewards members drive 60 percent of all U.S. revenue, visit about six times a month, and spend three times more per visit than non-members.
Walmart leans on the same instinct
Walmart Pay, the scan-to-pay tool at checkout, isn't a stored-value product itself, it's a way to check out faster using cards you've already linked to your account. But baked into it is a smaller version of the same idea. Add a Walmart gift card to your account, and Walmart Pay spends that balance down automatically before touching any other payment method. It’s a balance that keeps customers checking out inside Walmart's ecosystem instead of anywhere else.
When Walmart completed a nationwide rollout of Walmart Pay, and 88 percent of the people who try it become repeat users. That's an important data point, even the lightest version of "keep a balance with us" is sticky.
This isn't just a two company story
Between those two examples sits a real spectrum, from a bolt-on gift card balance to a fully designed stored-value account that earns interest and funds its own rewards. Any retailer with repeat purchase frequency sits somewhere on that spectrum already, whether that's grocery, pharmacy, convenience, apparel, or specialty retail. The customers are already coming back. The only question is whether their loyalty account can hold funds.
Stored value brings a host of benefits to retailers:
- Funds stay inside the ecosystem. A dollar loaded into your store's wallet is a dollar earmarked for your company.
- Balances earn money. Stored funds can generate interest on the balances customers hold with you, helping offset the cost of running the program.
- Flexible funding is built in. Customers load funds via ACH, direct deposit, card, or cash, and some of those funding methods carry no network fees at all, reducing payment costs.
- Refunds, discounts, and promotions can be added to a customer wallet, increasing the likelihood of return visits when those funds (and more) spent with your company.
What was impossible, isn’t anymore
What stops companies from emulating the Starbucks model? Building it means becoming a financial services operation. Holding customer funds, moving them, and protecting them means KYC, AML, and fraud protocols that look a lot more like a bank's obligations. That's historically been enough to keep the idea in the "someday" pile at most retailers.
That's changed. A licensed, regulated financial partner carries the compliance load, including KYC, AML, and fraud prevention. The company owns the customer experience, the app, and the rewards logic. The integration itself is API-first, with endpoints and webhooks lowering time to market.
Real money, real revenue via stored value
When a loyalty account is allowed to hold real money instead of just points, companies gain better retention, a new revenue line, and customers who show up more often and spend more when they do. The infrastructure behind a stored-value program, compliance, funding rails, wallet issuance, doesn’t need to be built from scratch. It’s possible, today.
