# The licensing reality: why most fintechs rent a bank charter
Chime is not a bank. Cash App is not a bank. Neither one holds the legal permission to hold your deposits or issue your debit card. Yet millions of people receive paychecks, swipe cards, and store money through these apps every day.
So where does the actual banking happen? Behind the scenes, at institutions most customers have never heard of: The Bancorp Bank, Stride Bank, Sutton Bank, and similar partners. These are chartered banks that rent out their licenses. Understanding this arrangement is the single most important thing to grasp about how modern fintech really works.
A bank charter is a government license to operate as a bank. In the US it is granted either by a state regulator or by the federal Office of the Comptroller of the Currency (the OCC). A charter is what legally lets an institution take deposits, lend, and access the payment rails that move money between banks.
Charters come with heavy obligations. A chartered bank must hold capital reserves, submit to regular examinations, follow anti-money-laundering rules, and carry FDIC insurance (Federal Deposit Insurance Corporation coverage that protects depositors, currently up to 250,000 dollars per depositor per bank).
Getting a charter is slow, expensive, and uncertain. It can take years and require tens of millions of dollars in capital. Most fintech founders do not want that. They want to ship an app.
The workaround is Banking as a Service (BaaS). A chartered bank partners with a fintech and lets that fintech offer banking products under the bank's license. The bank holds the deposits and takes on the regulatory responsibility. The fintech builds the app, the brand, and the .
Think of it like a restaurant that does not own the building. The fintech runs the kitchen and the dining room; the bank owns the property and holds the liquor license.
Here is how the money and compliance actually flow:
1. A customer deposits money into their Chime account.
2. That money does not sit at Chime. It sits at the partner bank (for Chime, this has been The Bancorp Bank and Stride Bank).
3. The deposit is FDIC insured through the partner bank, not through Chime.
4. When the customer swipes their debit card, the transaction settles through the partner bank's connection to the card networks (Visa or Mastercard).
The main revenue engine for many consumer fintechs is interchange: a small fee merchants pay every time a card is swiped. The card network sets the rate, the merchant's bank pays it, and it flows to the card-issuing bank. The partner bank and the fintech then split that interchange.
There is a regulatory twist that makes small partner banks attractive. Under the Durbin Amendment (part of the 2010 Dodd-Frank Act), banks with under 10 billion dollars in assets are exempt from caps on debit interchange fees. So they earn meaningfully more per swipe than a giant bank would. This is exactly why fintechs so often partner with small community banks like Sutton Bank or Stride Bank rather than a household name.
Money is only half the picture. Regulators do not care that a fintech "just makes the app." If customer money is involved, someone must run the compliance machinery.
That machinery includes:
Legally, the chartered bank is on the hook for all of it. In practice, the fintech usually operates the front-line systems and the bank oversees them. This split is where things get dangerous. If a fintech grows to millions of users but the partner bank's oversight team is small, the compliance gap can become enormous.
Regulators have made this point loudly. The OCC and the Federal Reserve have issued guidance stressing that a bank cannot outsource its responsibility, only the work. You can read the regulators' own framing in the interagency guidance on third-party relationships.
Renting a charter is fast and cheap to start. But the fintech pays for it in four ways.
The partner bank takes a cut of interchange and often charges platform fees. The fintech never keeps the full economics of a product it built.
The bank sets the rules. It can require the fintech to change features, tighten onboarding, or pause growth. If the bank gets nervous about risk, the fintech's roadmap stalls.
Many fintechs rely on a single partner bank. If that relationship ends, the fintech has to migrate every customer account to a new bank, a painful and risky project. Some larger fintechs now spread across multiple partner banks specifically to reduce this single point of failure.
Often there is a third player: a BaaS middleware provider that sits between the fintech and the bank, handling the technical plumbing. The 2024 collapse of the middleware firm Synapse is the cautionary tale here. When Synapse failed, a reconciliation breakdown meant many end customers of downstream fintechs could not access their own money for extended periods, because the records of who owned what did not line up cleanly across the parties. It exposed how fragile the chain can be when three companies share responsibility for one customer's balance.
The lesson from Synapse: the more layers between the customer and the actual chartered bank, the more places the chain can break, and the harder it is for a regulator or customer to know who is accountable.

Some fintechs do. There are three broad paths:
Owning a charter flips the tradeoffs. You capture full economics and control, but you inherit capital requirements, examinations, and direct regulatory liability. You become the restaurant that also owns the building and holds the license. Most fintechs decide the app is their edge and banking is not, so they keep renting.

The answers reveal how durable the business really is. A slick app on top of a single fragile bank relationship is a very different asset from a fintech with its own charter or diversified partners.
