Two prominent fintech firms — Rain and Modern Treasury — have formally applied for trust charters from the Office of the Comptroller of the Currency (OCC), positioning themselves among a rapidly expanding cohort of technology-driven financial companies seeking the legitimacy, operational scope, and regulatory standing that federal oversight can confer. The applications, reported by Banking Dive on October 6, 2026, arrive at a particularly charged moment: a trade group had filed a lawsuit against the OCC over the agency's trust charter framework just days prior, casting a shadow of legal uncertainty over the very pathway Rain and Modern Treasury are now pursuing.
The timing is notable precisely because it is defiant. Rather than retreating to wait out the legal turbulence, both companies have doubled down on their ambitions, signaling that the strategic calculus of operating under a federal charter — even a contested one — outweighs the risks of regulatory limbo. For fintech executives who have spent years navigating a patchwork of state licensing regimes, an OCC trust charter represents something qualitatively different: a single federal imprimatur that can streamline operations across all fifty states and communicate institutional credibility to enterprise clients, banking partners, and investors alike.
The OCC trust charter is not a full commercial bank license, but its appeal is nonetheless substantial. It grants holders the authority to conduct trust and fiduciary activities under federal supervision, bypassing the need to obtain individual state trust licenses in each jurisdiction where they operate. For fintechs like Rain — which operates in the payroll and earned wage access space — and Modern Treasury, a payments operations platform that automates money movement for businesses, such a charter would embed them more deeply into the infrastructure of the regulated financial system. It would also subject them to OCC examination authority, capital requirements, and compliance obligations — costs that many in the industry view as worthwhile in exchange for the predictability and reputational weight that federal oversight provides.
The broader trend here deserves attention. Rain and Modern Treasury are not outliers; they join what observers now describe as a growing list of fintech companies gravitating toward the OCC's trust charter framework. This movement reflects a maturing of the fintech sector, one in which the early-stage ethos of regulatory arbitrage — building fast, asking permission later — is giving way to a more deliberate posture of institutional integration. The largest enterprise customers, the most sophisticated investors, and the most risk-conscious banking partners increasingly demand regulated counterparties. A federal charter answers that demand directly.
Yet the legal challenge hanging over the OCC's trust charter program introduces real complications. The trade group lawsuit, filed just days before Rain and Modern Treasury went public with their applications, questions the legal foundation upon which the OCC has been granting or considering trust charters to non-depository fintech entities. While the specific grounds of the litigation were not fully detailed in initial reports, such suits have historically centered on questions of statutory authority — whether the OCC's enabling legislation actually permits it to extend trust charter privileges to entities that do not take deposits in the traditional sense. A prior wave of similar litigation, most notably around the OCC's Special Purpose National Bank charter initiative, dragged through courts for years before producing inconclusive outcomes that chilled industry participation.
If history is any guide, the applicants are bracing for a protracted process. Yet the decision to apply now — publicly, and in the immediate wake of a legal filing targeting the very instrument they seek — may itself be a strategic message to regulators, courts, and the market: that demand for this regulatory pathway is real, that it is growing, and that attempts to narrow or close it will face substantial pushback from the industry it is meant to govern.
For Modern Treasury in particular, a trust charter would represent a meaningful evolution. The company has built its reputation as a sophisticated back-end infrastructure provider, enabling businesses to orchestrate complex payment flows, reconciliation, and treasury operations through a modern application programming interface (API) layer. Federal trust status would not only enhance its credibility with the large financial institutions and corporate treasuries it serves, but could also open doors to a broader set of custodial and fiduciary service arrangements currently reserved for licensed trust entities. Rain, for its part, has positioned itself at the intersection of payroll technology and financial wellness, and a federal charter would strengthen its standing with the large employers and banking partners central to its business model.
What This Means for the Fintech Regulatory Landscape
The applications from Rain and Modern Treasury are best understood not as isolated corporate decisions but as data points in a larger structural shift. The fintech industry is entering a phase in which regulatory credentials are becoming a competitive differentiator rather than a compliance burden. The OCC trust charter, contested though it may be, sits at the center of that dynamic. How the courts resolve the pending trade group lawsuit will have consequences well beyond these two applicants — potentially determining whether the federal trust charter becomes a durable on-ramp for fintech firms seeking institutional legitimacy, or whether the pathway narrows once again, pushing companies back toward fragmented state-level licensing strategies. Either outcome will reshape competitive dynamics across payments, treasury technology, and earned wage access for years to come.
