Modern Treasury Files for OCC Trust Bank Charter to Custody Stablecoins
Modern Treasury, a payments infrastructure company that has processed more than $600 billion across hundreds of organisations, has applied to the Office of the Comptroller of the Currency (OCC) to charter Modern Treasury National Trust Bank. If approved, the institution would operate as a federally regulated, limited-purpose national trust bank, offering stablecoin custody and integrated fiat payment services to the company's existing corporate clients. For accounting firms and CFOs already wrestling with how to classify and disclose digital asset holdings, this application is a concrete signal that the regulatory plumbing for stablecoin custody is being built at the federal level, and that internal processes need to catch up.
What Modern Treasury Is Actually Applying For
A limited-purpose national trust bank is not a full commercial bank. It cannot take deposits from the general public, issue stablecoins, or make loans. Its permissible activities are narrower and tightly defined: holding assets in custody, acting as a fiduciary, and facilitating the movement of funds on behalf of clients. Modern Treasury has been explicit that the proposed bank would operate as a legally and operationally separate entity from its existing payments business.
The scope of the proposed charter
The application, submitted to the OCC, would allow Modern Treasury customers to custody stablecoins and move stablecoins alongside fiat within a single, integrated service. The CEO and co-founder described stablecoins as "foundational economic infrastructure," a framing that positions the charter application as a long-term infrastructure play rather than a short-term product launch. By operating under a federal charter, the bank would be supervised by the OCC rather than a patchwork of state money-transmitter licences, which currently governs most stablecoin-adjacent businesses in the US.
What the bank would not do
It bears repeating because it matters for accounting classification: this institution would not issue stablecoins and would not extend credit. That distinction is significant under emerging US stablecoin legislation and under FASB's proposed guidance on stablecoin classification. A custodian that holds but does not issue a stablecoin sits in a very different regulatory and accounting position from an issuer.
The Broader Race for Federal Trust Charters
Modern Treasury is not alone. The OCC has become a focal point for fintech and crypto firms seeking the predictability and interstate reach that a federal charter provides. Circle and BitGo have received final approvals for national trust charters. Kraken's parent company Payward, Zerohash, and Block have also filed applications. The queue is long and growing.
Why firms are choosing the OCC route
State-by-state licensing is expensive, slow, and produces inconsistent compliance obligations. A single OCC charter allows a firm to operate nationally under one regulatory framework. For a payments company with hundreds of corporate clients spread across multiple states, that simplification has obvious operational value. It also carries reputational weight: an OCC-chartered institution is subject to federal examination, capital adequacy expectations, and AML/BSA compliance standards that are, in principle, more rigorous and more uniform than many state equivalents.
Legal headwinds the applicants face
The path is not frictionless. Community banking groups have challenged the OCC's authority to issue trust charters to non-bank entities, and that litigation is ongoing. For a closer look at what the OCC crypto trust charter litigation means for firms, the legal risk to these applications is real and should feature in any due-diligence assessment of a custodian's regulatory status.
Accounting and Reporting Implications for Firms
When a corporate client holds stablecoins through a federally chartered trust bank, several accounting questions surface immediately, and the answers are not yet fully settled.
Custody arrangements and balance sheet presentation
Under US GAAP, assets held by a custodian on behalf of a client are generally recognised on the client's balance sheet, not the custodian's, provided the arrangement is a genuine agency or trust relationship rather than a transfer of ownership. A national trust bank, by definition, holds assets in a fiduciary capacity, which supports that treatment. However, firms will need to review the specific contractual terms of any custody agreement before reaching a conclusion. The FASB's ongoing work on digital asset classification, including its proposed guidance on stablecoins as potential cash equivalents, may also affect how these balances are presented once final rules are issued.
Disclosure requirements under ASC 820 and ASC 275
Stablecoins held in custody at a federally regulated institution are still subject to fair value disclosure requirements if the holding is material. Under ASC 820, entities must disclose the fair value hierarchy level for all financial instruments measured or disclosed at fair value. A USD-pegged stablecoin held at a trust bank custodian would typically fall into Level 1 or Level 2, but the classification depends on market depth and whether the stablecoin trades on active markets. Separately, ASC 275 requires disclosure of significant risks and uncertainties, which could encompass concentration in a single stablecoin or a single custodian, even a federally chartered one.
AML and BSA obligations shift upstream
When a corporate client moves from a state-licensed money transmitter to an OCC-chartered trust bank for stablecoin custody, the Bank Secrecy Act obligations of the custodian change in character. OCC-supervised institutions are subject to federal BSA examination, which typically means more rigorous customer due diligence standards, suspicious activity reporting, and transaction monitoring requirements. For accounting firms advising clients on their own AML compliance posture, this is relevant: the documentation your client needs to provide to an OCC-chartered custodian will likely be more extensive than what a state-licensed provider currently demands. Engagement letters and client onboarding procedures should be updated to reflect this.
Tax treatment of custodied stablecoin positions
From a US federal tax perspective, custodying a stablecoin at a trust bank does not itself constitute a taxable event. No disposal occurs when assets are transferred into custody, provided ownership does not pass to the custodian. However, any interest, yield, or other return generated on custodied stablecoins would be ordinary income in the period earned, and firms need to ensure their crypto bookkeeping software captures accruals at the transaction level rather than at settlement. The IRS treats digital assets as property, and stablecoins are not exempt from that treatment regardless of how close to par they trade.
Practical Steps for Accounting Firms and CFOs
The Modern Treasury application is a proposal, not an approval. The OCC review process can take many months, and approval is not guaranteed, particularly given the active litigation around the OCC's chartering authority. That timeline, however, is not a reason to defer internal preparation.
Reviewing custodian due diligence frameworks
Firms that advise clients holding stablecoins in custody, or CFOs managing treasury positions directly, should review their custodian due diligence checklists now. Key questions include: Is the custodian operating under a state licence or a federal charter? What capital adequacy standards apply? How are client assets segregated in the event of custodian insolvency? A federally chartered trust bank answers some of these questions more cleanly than a state-licensed provider, but the contractual terms still need scrutiny.
Updating accounting policies and system configurations
As custody arrangements shift to federally regulated entities, the metadata associated with each stablecoin holding changes: the custodian type, the regulatory jurisdiction, the applicable capital regime, and the contractual terms of the fiduciary relationship all feed into how the position is classified and disclosed. Digital asset accounting software should be configured to capture custodian-type data at the wallet or account level so that financial statement preparers can pull accurate disclosures without manual reconstruction. This is particularly relevant for firms that manage multiple clients with stablecoin treasury positions, where the volume of holdings makes manual tracking impractical.
Monitoring the OCC application pipeline
With Circle, BitGo, Payward, Zerohash, Block, and now Modern Treasury all in the OCC pipeline, the probability that at least some of your clients will interact with an OCC-chartered custodian in the next 12 to 24 months is high. Building familiarity with what that means for audit procedures, internal controls, and financial statement disclosures ahead of approval is considerably cheaper than scrambling after the fact. For context on the systemic dimensions of stablecoin custody risk, the analysis of stablecoin bank-run risk and what CFOs need to know remains directly relevant to any firm evaluating custody counterparty risk.
What This Means for Crypto Compliance Reporting
The Modern Treasury application is one more data point in a clear directional trend: stablecoin infrastructure in the US is migrating toward federal regulatory frameworks, driven by the OCC charter process, the ongoing Congressional debate over stablecoin legislation, and the FASB's work on accounting classification. For firms that advise clients on crypto compliance reporting, the practical implication is that the standards against which custody arrangements are assessed will become more demanding, not less.
Crypto accounting software that can track custodian regulatory status, flag changes in custodian type, and automate the disclosure language required under ASC 820 and ASC 275 will reduce the manual burden significantly as this landscape evolves. The firms that build those capabilities now, rather than after the first OCC-chartered stablecoin custodian goes live with a major corporate client, will be better positioned for the compliance workload ahead.
Frequently Asked Questions
What is a limited-purpose national trust bank?
It is a federally chartered institution supervised by the OCC that is authorised to act as a trustee, fiduciary, or custodian. It cannot accept public deposits, issue loans, or, in Modern Treasury's proposed case, issue stablecoins. Its permissible activities are defined in its charter application and approved by the OCC.
Does transferring stablecoins to an OCC-chartered custodian trigger a taxable event?
No, provided the transfer is a true custodial arrangement in which beneficial ownership remains with the client. The IRS treats digital assets as property, and a change in custody without a change in ownership is not a disposal for tax purposes. However, any yield or return earned on custodied assets is taxable income in the period it accrues.
How should stablecoins held at a trust bank custodian be presented on the balance sheet?
Under a genuine trust or agency arrangement, the assets remain on the client's balance sheet, not the custodian's. FASB's current and proposed guidance, including the proposal to classify certain stablecoins as cash equivalents, will affect the line-item presentation once finalised. Firms should monitor FASB developments and review the specific contractual terms of each custody agreement.
What AML obligations apply to an OCC-chartered trust bank?
OCC-supervised institutions are subject to full Bank Secrecy Act requirements, including customer due diligence, beneficial ownership verification, transaction monitoring, and suspicious activity reporting. This is a more demanding framework than many state money-transmitter licences, and corporate clients should expect more rigorous onboarding documentation requirements when working with a federally chartered custodian.
How should accounting firms adjust their audit procedures for clients using an OCC-chartered stablecoin custodian?
Auditors should obtain and review the custody agreement to confirm the fiduciary nature of the arrangement, verify that client assets are segregated from the custodian's own assets, assess the custodian's regulatory examination history where available, and confirm that the client's crypto bookkeeping software captures the correct custodian metadata for disclosure purposes. Standard confirmations sent to custodians should be adapted to address digital asset-specific risks.
