Modern Treasury files for OCC trust bank charter to custody stablecoins and fiat
The proposed Modern Treasury National Trust Bank would not issue stablecoins or make loans.
Modern Treasury has submitted an application to the Office of the Comptroller of the Currency to form a limited-purpose national trust bank focused on stablecoin custody and integrated fiat movement. The company says the proposed bank would not issue stablecoins or extend credit, keeping the charter push narrowly aimed at regulated rails.
Modern Treasury filed to create “Modern Treasury National Trust Bank,” a federally regulated, limited-purpose national trust bank under the Office of the Comptroller of the Currency. The OCC is the US regulator that charters and supervises national banks. The application is a direct bid to put stablecoin custody and fiat movement inside a federal wrapper.
Modern Treasury’s stated scope is tight. If approved, the trust bank would let customers custody and move stablecoins and fiat through an integrated service, while explicitly not issuing stablecoins and not making loans. That matters because it draws a line between “plumbing” and “product,” and it keeps the proposal closer to custody and payments operations than to balance-sheet risk.
A limited-purpose national trust bank is built for trust and custody services rather than traditional banking activities like deposit-taking and lending. In this case, the pitch is stablecoin custody: holding and safeguarding stablecoin assets on behalf of customers and enabling transfers. The announcement did not include product specifics such as which stablecoins would be supported, how custody would be structured, or which client segments would be eligible.
Modern Treasury is also trying to ring-fence the new regulatory perimeter. The company said the proposed bank would operate separately from its existing payments business, which it said has facilitated more than $600 billion in payments across hundreds of organizations. CEO Matt Marcus framed the move as an extension of what the platform already does, saying the company has “fully integrated stablecoins into its payments platform” and adding, “We believe stablecoins are foundational economic infrastructure for the future.”
The filing lands in a market structure moment where more firms want regulated access to stablecoin settlement without becoming issuers. Modern Treasury positioned its application alongside other national trust bank charter efforts it cited across crypto and payments, including conditional approvals for Bastion and Ripple, final approvals for Circle and BitGo, and applications submitted by Payward (Kraken parent), Zerohash, and Block. The announcement did not provide dates or documentation for those statuses.
What Approval Would Change for Stablecoin Rails—and What to Monitor Next
If the OCC approves the application, Modern Treasury would be able to sell institutions a federally regulated custody wrapper for stablecoins alongside fiat movement. The practical implication is counterparty selection. Some flows that currently clear through non-bank custody arrangements could migrate toward a national-bank chartered entity if procurement and compliance teams treat the charter as a gating item.
The catch is timing and scope. No OCC decision timeline was provided, and the application’s path can include public updates such as acceptance, comment periods, conditional approval, or denial. Those milestones matter more than the headline because they determine whether this becomes a real rails expansion or stays a narrative.
Product detail is the other missing input. Market impact depends on which stablecoins are supported, whether custody is segregated or omnibus, whether assets are held onchain directly or through a third-party custodian, and how fiat rails integrate with stablecoin transfers. Without those specifics, it is hard to handicap whether the trust bank would be a new settlement venue for large accounts or a compliance wrapper around existing workflows.
Modern Treasury’s “no issuance, no loans” stance is also a live variable. The company drew that boundary in the announcement, but the application process is where firms sometimes broaden scope, narrow scope, or add conditions. Any shift there changes the risk profile and the competitive set.
Finally, watch the follow-on behavior from other payments and crypto firms. More filings would signal that the federal-charter lane is becoming the default route for stablecoin custody and fiat connectivity, which raises the bar for unregulated or lightly regulated custody providers competing for the same institutional mandates.
My Read: The Charter Push Is About Regulated Access to Stablecoin Plumbing, Not New Tokens
The threshold that matters is whether the OCC moves this application into a visible review track with concrete milestones. Without that, the market only has intent, not a new regulated venue for stablecoin settlement.
What stands out is the deliberate constraint: custody and movement, no stablecoin issuance, no lending, and a separate operating perimeter from the existing payments business that claims $600 billion in processed volume. If those constraints hold through the process, this looks more like a bid to own regulated stablecoin plumbing for enterprise flows than a push to manufacture new token supply or take credit risk, and that is where the durable advantage would sit.
