A Bank Charter Replaces Partner Risk With Execution Risk
Executive summary
The Office of the Comptroller of the Currency gave preliminary conditional approval on September 2 to two very different proposed national banks: Revolut Bank US and OpenReserve Bank. The immediate interpretation is that fintechs are moving upstream, cutting out sponsor banks and gaining direct control of deposits, lending and payments.
That reading is directionally right but economically incomplete. The approval letters do not describe a simple release from dependence. They replace one form of dependence with a more demanding operating contract: permanent capital, fixed compliance infrastructure, pre-opening tests, restrictions on strategic deviation and continuing regulatory consent for some products. The charter can improve product control and unit economics, but only if the platform has enough scale and discipline to absorb those costs.
The contrarian thesis is that the current charter wave will widen the gap between scaled platforms and merely popular fintech interfaces. Distribution creates the option to become a bank. Capital efficiency, governance and operational readiness determine whether exercising that option creates value.
Market context
Revolut currently serves U.S. customers through FDIC-insured partner banks. Its proposed full-service digital bank is intended to offer deposits, credit, payments, digital-asset services and financial-management tools directly to retail and business customers. Revolut told customers that a charter should enable a broader product set and direct access to payment networks such as ACH and Fedwire. The company says it has more than 80 million customers globally and is targeting a U.S. bank launch in 2027.
OpenReserve starts from the opposite end of the market. It is a new institutional platform that proposes deposits and lending, tokenized capabilities, payments, treasury, digital-asset services, foreign correspondent banking and banking as a service. It also plans a wholly owned stablecoin subsidiary, although the OCC letter says that subsidiary application has not yet been filed.
Both approvals are preliminary. Neither bank may open until it has met the OCC's conditions and pre-opening requirements. Both must obtain deposit insurance from the Federal Deposit Insurance Corporation and become members of the Federal Reserve System. The OCC can modify, suspend or rescind an approval before opening if material facts change.
The paired decisions are useful because they expose the price of two strategies. Revolut brings an existing customer base and wants to internalize economics now shared with partners. OpenReserve is raising capital to build a bank-native infrastructure platform. If a charter were simply a regulatory switch, their conditions would look interchangeable. They do not.
Findings
Finding 1
The charter internalizes control, not complexity.
Revolut's stated logic is familiar: serving U.S. customers through its own bank should be cheaper and more efficient than the partner-bank model and should allow a broader package of services. Direct deposits can provide funding. Direct payment-network access can reduce handoffs. Lending can add net interest income, while one balance sheet can simplify product design across spending, saving and borrowing.
But the partner bank had been carrying regulated functions that do not disappear. They move inside Revolut. The proposed bank must operate Bank Secrecy Act and sanctions controls, credit-risk management, allowance-for-credit-loss processes, third-party oversight, information security, business continuity, internal audit and board governance. It must submit its final systems architecture and risk plan for supervisory review and complete an independent security test before opening.
This changes the unit-economics equation. A sponsor-bank fee is visible and variable. An internal regulatory stack is partly fixed, partly capital intensive and harder to allocate to a product. At high scale, owning the stack can lower marginal cost and increase speed. Below that scale, removing an intermediary can raise total cost.
The same principle applies to product velocity. Revolut must give the OCC at least 60 days' notice before a significant deviation from its business plan and obtain a written no-objection determination. That condition remains through its first three years. Merchant acquiring, foreign non-affiliate correspondent banking and certain foreign-exchange products require additional written no objection before launch. A charter expands the perimeter of what the company may ultimately do, while reducing the freedom to improvise inside that perimeter.
That is not a regulatory flaw. Deposits and payment access make execution errors more consequential. It does mean operators should reject the loose claim that bank ownership automatically makes a fintech faster.
Finding 2
The approval letters price business-model risk through capital.
The OCC requires Revolut Bank US to begin with at least $95 million of paid-in capital after organizational and pre-opening expenses and to maintain a minimum 10% tier 1 leverage ratio for its first three years. OpenReserve must begin with at least $210 million and maintain at least a 12% tier 1 leverage ratio over the same period.
The difference is informative. OpenReserve proposes a broader institutional and digital-asset operating model, including tokenized deposits, banking as a service, foreign correspondent banking and a future stablecoin subsidiary. Its higher starting capital and leverage floor indicate that the regulator is not treating an on-chain architecture as a way around balance-sheet discipline. The newer the operating model, the more expensive resilience can become.

Source: Blackrock Research compilation from OCC Corporate Decision 1390 and Corporate Decision 1389, both dated September 2, 2026. Units are U.S. dollars and regulatory capital ratios. The table summarizes preliminary approvals, not authority to commence banking. Product descriptions are proposed and remain subject to stated conditions and other approvals.
Starting capital is only the first denominator. The leverage ratio limits asset growth relative to tier 1 capital. Compliance personnel, independent audits, security testing and board oversight add recurring expense. A new bank therefore needs contribution from deposits, payments, lending and services sufficient to cover both operating cost and the opportunity cost of equity.
For a scaled consumer platform, the bet is that a large installed base can fund that burden. For a bank-infrastructure startup, the bet is that institutional customers will pay enough for integrated ledgers, treasury and regulated digital-asset services to produce a return on a much larger capital base. These are different businesses despite sharing a charter category.
Finding 3
The scarce asset is controlled adaptability, not the legal charter alone.
The mainstream narrative treats a national charter as a moat because it unlocks nationwide banking authority and reduces reliance on sponsor banks. Yet a charter is available to more than one credible applicant, and the OCC's public index shows a busy 2026 pipeline of fintech, digital-asset and foreign-bank decisions. The legal status may become less differentiating as more applicants advance.
What remains scarce is the ability to change products without breaking capital, compliance or control assumptions. Both banks will need regulatory no objection for material deviations during their first three years. OpenReserve must also conform its stablecoin activities to the GENIUS Act, implementing regulations and other future rules as determined by the OCC. Its proposed stablecoin subsidiary still needs a separate filing.
This makes architecture a strategic constraint. A bank that can trace customer consent, funds flow, ledger state, risk limits and third-party responsibility can introduce new products with clearer evidence. A bank that has tightly coupled growth experiments to opaque vendors or manual controls will move slowly even if its charter permits the activity in principle.
The distinction matters for partners and customers. A merchant or fintech buying banking services from a newly chartered platform should not treat the charter as a substitute for diligence. It should ask which entity holds the deposit, which ledger is authoritative, how settlement and reconciliation work, what happens during a vendor outage, which services have final approval and how a product wind-down would be handled.
The same caution applies to stablecoins. Revolut's proposed bank would not issue its branded stablecoin or manage the reserves; a third party would do so, while the bank's role would be marketing, access and custody through an affiliate. OpenReserve proposes a bank-owned issuer but has not yet filed that subsidiary application. “Bank-backed” can therefore describe materially different legal, reserve and operational arrangements.
Implications for operators
Fintech boards considering a charter should model it as a make-versus-buy decision over a regulated production system. The comparison should include sponsor fees and lost product flexibility on one side; capital cost, regulatory staffing, audit, security, credit losses, liquidity and slower change control on the other. Gross revenue recapture is not the same as economic value creation.
Product leaders should separate permission from launch readiness. A charter may make an activity legally available, but the approval letter, pre-opening examination or a separate subsidiary filing can still gate delivery. Roadmaps need a regulatory critical path with evidence owners, not a single “license received” milestone.
Treasury teams should measure the return on constrained capital by business line. Deposit growth can be valuable funding, but it also expands operational and liquidity obligations. Lending can deepen relationships, but it introduces loss provisioning and concentration risk. Digital-asset revenue may be strategically visible while remaining small in the bank's financial mix; Revolut projects it at less than 2% of total bank revenue during the three-year de novo period.
Prospective clients of chartered fintech infrastructure should negotiate portability even when the counterparty is a bank. Exportable ledger data, reconciliation files, transition assistance, incident reporting and clear ownership of compliance tasks still matter. Chartering changes the regulator and balance-sheet arrangement. It does not abolish vendor concentration.
Risks & open questions
The approvals may never translate into operating banks on the proposed timetable. Revolut's approval expires if capital is not raised within 12 months or the bank does not open within 18 months; the same deadlines apply to OpenReserve. FDIC decisions, Federal Reserve membership, pre-opening examinations and technology readiness remain unresolved.
The report's thesis would be weakened if newly chartered fintech banks consistently show faster launches, lower total operating cost and higher risk-adjusted returns than comparable partner-bank models after accounting for equity capital. Evidence of lower customer prices and fewer operational failures at similar credit performance would also support the mainstream view more strongly than the conditional letters alone.
Conversely, repeated delays, high capital consumption, regulatory restrictions or continued dependence on outside banks for core functions would show that charter ownership moved the bottleneck rather than removed it.
There is also a comparability limit. The OCC letters disclose conditions, not full business plans, projected balance sheets or commercial contracts. The difference between $95 million and $210 million should be read as evidence of distinct approved risk profiles, not as a standalone measure of which company has the better strategy.
Appendix / methodology notes
This report reviewed the OCC's September 2, 2026 preliminary conditional approvals for Revolut Bank US, National Association and OpenReserve Bank, National Association; the OCC's public interpretations and decisions index; Revolut's September 3 announcement and U.S. customer notice; and OpenReserve's launch materials. Company claims about customer counts, costs, launch timing and market opportunity are attributed rather than treated as audited outcomes.
The comparison table reproduces or summarizes explicit terms in the approval letters. “Initial paid-in capital” is net of organizational and pre-opening expenses. Tier 1 leverage ratios apply throughout the first three years of operation. Neither approval is a final charter or permission to accept deposits today.
No forecast has been assigned to deposits, loan growth, stablecoin volume or profitability because the public materials do not provide a consistent observed dataset. The most useful future chart would compare quarterly deposits, net interest margin, noninterest revenue, credit losses, operating expense and tier 1 leverage from opening through year three against a matched set of sponsor-bank fintechs. That dataset does not yet exist.
