The US Office of the Comptroller of the Currency has rejected Dutch fintech Bunq's application for a national bank charter, citing significant supervisory and compliance concerns, according to a denial letter dated 4 August 2026. The decision, first reported publicly on 7 August 2026, marks a significant setback for one of Europe's largest challenger banks in its ambitions to establish a regulated presence in the United States.
In its letter, the OCC pointed to concerns including how Bunq would be capitalised in the US and questions over management experience with unsecured credit cards. The agency described the concerns as significant supervisory and compliance issues, language that reflects the substantive nature of the objections rather than a purely procedural refusal.
REAPPLICATION FALLS SHORT
Bunq had reapplied for a US bank charter in January 2026, after withdrawing an earlier application in early 2024. The renewed application followed the Amsterdam-based challenger bank's receipt of a FINRA-approved broker-dealer licence in 2025, which the company had presented as a stepping stone to broader US financial services activities and evidence of its ability to obtain regulated status in the country.
The OCC's denial marks a setback for Bunq's US ambitions and highlights the difficulty foreign digital banks face in obtaining top-tier US banking authorisations. The comptroller has historically insisted that any national bank charter applicant demonstrate robust capital plans, management depth and controls appropriate to the proposed business model, particularly in relation to consumer credit products that carry higher risk profiles.
Capitalisation concerns of the kind flagged in the letter typically relate to how the parent structure would inject and maintain capital in the US bank subsidiary, and how that capital would be protected in stressed conditions. Management experience with unsecured credit cards, another cited issue, is a specific concern that reflects the OCC's caution around portfolios that can generate significant losses in an economic downturn.
WISE ALSO REJECTED LAST MONTH
The Bunq decision comes a month after the OCC rejected Wise's application to become a national trust bank for similar reasons. Two consecutive denials of high-profile European fintech applications signal a cautious stance from the US regulator towards granting national charters to foreign-owned digital banks that have not previously operated in the US retail banking market, and set a difficult precedent for other applicants at similar stages of their US strategy.
For foreign fintechs, the pattern suggests that a US national bank charter remains one of the most demanding authorisations to obtain, and that supervisors will apply particular scrutiny to capital, governance and product experience where the applicant is a digital-first institution with a foreign parent. Alternative pathways such as trust bank charters, state banking licences or partnerships with existing US banks may become relatively more attractive.
Bunq has built a European retail deposit and payments franchise from its Dutch base and has expressed a longer-term ambition to serve customers in the US. With a national bank charter now unavailable, the company will need to consider alternative regulatory pathways if it intends to pursue that ambition, and will likely face questions from investors and partners about how it plans to progress its US strategy.
