OCC Rejects bunq’s U.S. Bank Charter Application Over Supervisory and Compliance Concerns

The United States Office of the Comptroller of the Currency has rejected Dutch digital bank bunq’s application for a national banking charter, citing significant concerns about the proposed institution’s capitalisation, management experience, business strategy and ability to operate safely and profitably in the U.S. market. The decision represents a setback for bunq’s plans to establish a full banking presence in the United States and highlights the demanding regulatory expectations facing European fintech companies seeking to enter the American banking system.

The OCC issued its decision on 4 August 2026 in relation to an application to establish bunq US Bank, N.A., in New York. The proposed bank would have been backed by Bunq US Holding LLC, with bunq founder and chief executive Ali Niknam ultimately holding a majority interest through the proposed ownership structure. Niknam also controls bunq B.V., the Netherlands-based banking institution that operates under European regulatory supervision.

The regulator concluded that the application presented significant supervisory and compliance concerns. Among the principal issues identified were uncertainty surrounding the proposed bank's capitalisation, limited management experience with certain products that would form an important part of the U.S. business, weaknesses in the proposed business plan and doubts over whether the institution could achieve sustainable profitability.

Capital adequacy was one of the central issues. The OCC determined that the application did not adequately demonstrate how the proposed U.S. bank would be capitalised and how sufficient capital would be maintained as the business developed. For a new bank, demonstrating access to sufficient capital is a fundamental regulatory requirement because the institution must be able to absorb losses, support growth and remain financially stable without creating unnecessary risks for customers or the wider financial system.

The regulator also questioned the experience of the proposed management team, particularly in relation to unsecured credit card lending. Credit cards were expected to form an important part of bunq's planned U.S. offering, but the OCC concluded that the proposed leadership did not demonstrate sufficient experience with the specific risks associated with this type of lending in the American market.

This distinction is important because experience operating a digital bank in Europe does not automatically demonstrate the ability to manage the risks associated with U.S. consumer credit. Credit underwriting, regulatory requirements, consumer behaviour, competition and loss patterns can differ substantially between markets.

The OCC also expressed concerns about the proposed leadership structure. The regulator questioned whether the proposed chief executive would be sufficiently involved in the day-to-day management of the U.S. institution, particularly given plans that would have involved the executive spending significant periods outside the United States. The concern reflects the importance regulators place on having senior management that can provide effective and continuous oversight of a newly established bank.

Business planning was another major issue. The OCC concluded that bunq's projections for its U.S. operations were unrealistic and that the application did not provide sufficient evidence that the proposed institution could operate safely while achieving profitability in a highly competitive market. The regulator questioned assumptions concerning customer acquisition, lending activity and the level of losses that could arise from the planned credit-card business.

For a fintech seeking a bank charter, this is particularly significant. A successful digital platform and a large customer base do not necessarily demonstrate that a proposed banking subsidiary can satisfy the capital, governance, risk-management and profitability standards expected of a regulated U.S. bank.

bunq has already established a substantial presence in Europe and has built a large customer base across multiple markets. The company also obtained a U.S. broker-dealer licence approved by the Financial Industry Regulatory Authority in 2025, allowing it to provide investment-related services. The bank charter application was intended to take its U.S. activities further by enabling the company to operate as a fully licensed banking institution.

The rejection is not bunq's first difficulty in obtaining a U.S. banking charter. The company previously submitted an application but withdrew it at the beginning of 2024. It subsequently reapplied in January 2026 after developing its plans for the U.S. market.

Bunq has indicated that it intends to address the regulator's concerns and continue pursuing a U.S. banking presence. The company has characterised the OCC's feedback as an opportunity to develop a plan more specifically tailored to the U.S. market, strengthen its experience in the products it intends to offer and provide greater detail concerning its financial structure.

The OCC's decision does not permanently prevent bunq from seeking a banking charter in the future. The regulator's decision expressly leaves open the possibility of a new application once the identified deficiencies have been addressed.

The case is particularly relevant because it follows another recent rejection involving a major European fintech. In July 2026, the OCC rejected Wise's application to establish a national trust bank, also citing supervisory and compliance concerns. That decision included concerns relating to anti-money laundering and counter-terrorist financing controls, as well as management experience.

The two cases indicate that the OCC is applying considerable scrutiny to fintech businesses seeking to move from technology-driven financial services into direct banking relationships with U.S. customers. Although the regulatory environment may be becoming more receptive to fintech banking applications, applicants are still expected to demonstrate that they can satisfy traditional standards of capital strength, management competence, compliance and risk management.

The development also illustrates an important distinction between being a fintech company and being a bank. Fintech businesses can provide financial products through partnerships with licensed institutions while relying on those banks for certain regulated functions. Obtaining a banking charter transfers a much greater degree of regulatory responsibility directly to the fintech itself.

A chartered institution must demonstrate that it has appropriate governance structures, risk-management systems, capital resources, compliance personnel and operational controls before it begins operating. These requirements are particularly important where the proposed business model involves unsecured consumer lending, because credit risk can develop rapidly during periods of economic stress.

The bunq decision therefore provides a useful reminder that regulatory readiness must extend beyond technology and customer acquisition. A sophisticated digital platform may provide an effective customer experience, but regulators also need assurance that the underlying institution can manage financial, operational, compliance and consumer risks.

Capital planning is especially important for new banks. Regulators need to understand where initial capital will come from, how much capital will be available, how it will be maintained and how the institution will respond if losses or growth requirements exceed initial projections.

The concerns surrounding bunq's business plan also highlight the importance of realistic financial modelling. A proposed bank must be able to demonstrate not only how it expects to acquire customers but also how it will generate sustainable revenue, control operating costs, manage credit losses and maintain adequate liquidity and capital.

For European fintechs seeking U.S. expansion, the case demonstrates that existing success in Europe cannot simply be transferred into a new jurisdiction without significant adaptation. The U.S. market has its own regulatory framework, consumer-credit environment and competitive landscape, requiring applicants to develop strategies specifically designed around those conditions.

Management experience is another area likely to receive increased attention. Regulators may examine whether senior executives and board members have practical experience in the particular products the proposed bank intends to offer and whether they understand the regulatory obligations associated with operating a U.S. financial institution.

The OCC's concerns over unsecured credit cards illustrate this point. A company can have extensive experience operating payment accounts or other financial products while still lacking the specific expertise required to manage a large unsecured consumer-credit portfolio.

The proposed leadership arrangements can also become a regulatory issue. A new bank requires clear accountability and effective oversight, particularly during its early years. Regulators may therefore be reluctant to approve structures in which key executives have competing responsibilities or are expected to spend substantial amounts of time outside the institution's principal market.

The case has broader implications for the financial technology sector because many successful fintechs are now attempting to move further into regulated banking activities. Obtaining their own licences can provide greater control over products and customer relationships, but it also exposes them directly to the full range of prudential and compliance expectations applied to traditional financial institutions.

From an AML perspective, the lesson is equally important even though the bunq decision was not based solely on money laundering concerns. Compliance must be integrated into the institution's overall operating model from the beginning rather than treated as an additional requirement to be addressed after the commercial strategy has been developed.

A bank charter applicant needs to demonstrate that it can identify and manage financial crime risks, implement appropriate customer due diligence, monitor transactions and maintain effective governance. Those systems must be supported by sufficient staffing, technology and senior-management oversight.

The broader regulatory pattern also suggests that fintech applicants should expect regulators to examine whether their existing compliance culture can withstand the responsibilities associated with becoming a bank. A company that has historically operated through partnerships with licensed institutions may need to substantially expand its internal compliance and risk-management capabilities when it becomes a direct regulated entity.

For bunq, the immediate effect is a delay to its U.S. banking ambitions. The company can continue operating within the scope of its existing U.S. authorisations, including its broker-dealer activities, while considering how to respond to the OCC's concerns. Its longer-term strategy will depend on whether it can demonstrate that the identified weaknesses have been resolved.

The rejection does not necessarily represent the end of bunq's U.S. ambitions. The OCC has left the door open to another application, meaning the company could potentially return with a revised business model, stronger capitalisation plan and management structure designed specifically around U.S. regulatory expectations.

The case nevertheless demonstrates that obtaining a banking charter is fundamentally different from obtaining permission to offer individual financial products. A bank charter carries prudential responsibilities that require the applicant to demonstrate financial resilience, sound governance and operational readiness before being allowed to commence full banking activities.

For other fintechs considering a similar route, the decision provides a number of important lessons. Applicants need to develop a detailed U.S.-specific business plan, demonstrate credible access to capital, appoint management with relevant local and product expertise and establish robust compliance and risk-management frameworks before approaching the regulator.

The rejection also shows that regulators are prepared to challenge optimistic growth projections where they believe those projections do not adequately reflect competitive pressures or potential losses. A compelling technology proposition is therefore unlikely to compensate for weaknesses in financial modelling or risk management.

The timing of the decision is particularly notable because it follows the OCC's rejection of Wise's proposed U.S. trust bank. Taken together, the cases suggest that fintech applicants cannot assume that a technology-friendly regulatory environment means lower expectations for governance, compliance and financial soundness.

The regulatory scrutiny also highlights the growing importance of demonstrating genuine local capability. International fintechs entering the U.S. market need to show that their governance, management and compliance structures are capable of operating effectively within the American regulatory environment rather than simply extending European systems into the United States.

Ultimately, the bunq decision reinforces a fundamental principle of banking regulation: innovation and scale do not replace the need for sound financial management and effective controls. A company may have millions of customers, a successful technology platform and extensive experience in other jurisdictions, but a banking charter requires a separate demonstration that the institution can operate safely, responsibly and sustainably within the U.S. financial system.

For bunq, the next step will be to address the OCC's concerns and determine whether its U.S. strategy can be redesigned to satisfy the regulator. For the wider fintech sector, the case provides a clear warning that obtaining a U.S. bank charter requires much more than a strong product and ambitious growth projections. Capital, governance, management expertise, compliance infrastructure and credible financial planning remain fundamental conditions for entering the U.S. banking system.
