What Bunq’s OCC Rejection Teaches Foreign Fintechs
following the OCC’s rejection of Bunq’s US bank charter application, foreign challenger banks face a clear reality check: European operating models cannot simply be “passported” into federal US regulation.

Dutch digital challenger bank, Bunq, faced a major strategic setback in its US expansion after the Office of the Comptroller of the Currency (OCC) rejected its application for a national bank charter. In an August 4 letter, the federal banking watchdog cited “significant supervisory and compliance concerns”, leaving the challenger bank to re-evaluate its transatlantic strategy.
While Bunq successfully secured a FINRA-approved broker-dealer license in 2025 to offer investment products to US retail investors, federal banking regulators made it clear that capital markets permissions do not translate to full-scale banking rights.
The rejection highlights several key lessons for European fintechs attempting to enter the US market:
-
A Brokerage License Is Not a Banking Shortcut: A FINRA license grants distribution rights for investments, but national bank charters demand comprehensive balance-sheet scrutiny, consumer protection mechanisms, and deposit safety standards under the OCC.
-
Capital Sourcing Demands Total Transparency: The OCC highlighted serious gaps in Bunq’s capital planning. Bunq initially proposed $50 million sourced from CEO Ali Niknam’s personal funds, later modifying the structure to a corporate dividend and revising the figure to $58.3 million without sufficient detail regarding the source of the additional funds.
-
Local Leadership Matters: The regulator flagged management’s lack of experience with US national banking laws and unsecured credit products (Bunq’s primary proposed lending asset). The OCC specifically pointed out that executive oversight was proposed on a part-time basis across multiple entities.
-
European Economics Don’t Mirror the US Market: Bunq’s European profits were heavily bolstered by interest rate movements. The OCC deemed Bunq’s US customer acquisition projections and loan-loss allowances “unrealistic” given the fierce competition from incumbent US card issuers.
The State of Play in the US Market
Foreign fintechs face a high regulatory bar in the US market. The OCC maintains stringent standards regarding capital strength, credit risk modelling, and local governance.
| OCC Charter Review Category | Key Criteria & Regulatory Expectations |
|---|---|
| Financial Structure | Unambiguous, fully verified capital sources and peer-tested credit loss provisions. |
| Governance & Leadership | Dedicated local executives with deep expertise in US federal banking laws and fiduciary standards. |
| Market Strategy & Risk | Demonstrated BSA/AML compliance frameworks alongside defensible acquisition costs for the US credit market. |
The OCC’s stance reflects a broader shift: European-style “passporting” logic does not apply under US federal banking frameworks. Regulators expect de novo entities to present battle-tested, locally adapted risk models on day one rather than adapting European frameworks after launch.
Comparing Setbacks: Bunq vs. Wise
Bunq’s rejection mirrors a similar decision by the OCC involving UK cross-border payments provider Wise.
| Feature | Bunq | Wise |
|---|---|---|
| Target License | National Bank Charter | National Trust Bank Charter |
| Primary Regulatory Concern | Capitalisation transparency, credit risk modeling, and US-specific market experience. | BSA/AML compliance history and fiduciary governance experience. |
| Product Focus | Unsecured credit cards & consumer lending. | Direct payment rail access & fiduciary clearing services. |
| Regulatory Footprint | Reapplied post-2024 withdrawal; holds a FINRA broker-dealer license. | Subject to prior multistate AML enforcement actions & regulatory consent orders. |
| Strategic Response | Remediating capital & governance feedback to resubmit application. | Revising compliance frameworks to submit a new application. |
While Wise sought a non-depository trust charter to gain direct clearing system access without offering credit, the OCC still rejected its application citing anti-money laundering compliance risks and insufficient leadership experience with US banking law. Together, the two decisions demonstrate that regardless of whether a business model focuses on payments or consumer lending, regulatory scrutiny remains focused on risk governance, compliance structures, and localized management depth.
Both firms have indicated plans to address the regulator’s feedback and submit updated applications. For fintech leaders on both sides of the Atlantic, the core takeaway is clear: expanding into the US market requires establishing a ground-up risk and compliance infrastructure built specifically for federal oversight.
