The latest CLARITY Act text, released July 22, preserves language that has been stable since the Senate Banking Committee advanced the bill on May 14. The provision that matters most for payment institutions operating outside traditional banking charters is straightforward: digital assets must be held with a Qualified Digital Asset Custodian, defined as an entity subject to supervision and examination for custody by a federal or state banking regulator, the CFTC, or the SEC. This isn't new language. But combined with the GENIUS Act's custody restrictions, already signed into law in July 2025, it creates a federal architecture that appears to route stablecoin settlement infrastructure through banking and broker-dealer licensing regimes.
The GENIUS Act made this explicit: entities may only provide custodial or safekeeping services for stablecoin reserves if they are subject to supervision by a primary federal payment stablecoin regulator, a primary financial regulatory agency, or certain state bank supervisors. The OCC's proposed implementing rules, published in March 2026, apply to national banks, federal savings associations, federal branches, and nonbank entities seeking federal qualified payment stablecoin issuer status. The FDIC's parallel rulemaking, approved in April 2026, establishes similar requirements for insured depository institutions. Neither framework contemplates a role for payment institutions licensed under regimes comparable to Europe's EMI structure.
This matters because institutional demand for stablecoin settlement is no longer theoretical. Visa's stablecoin settlement program reached a $4.5 billion annualized run rate by January 2026. B2B stablecoin payments have grown from under $100 million monthly in early 2023 to over $6 billion by mid-2025. The operational case is clear: blockchain-based cross-border payments can reduce all-in transaction costs to 0.1, 0.5%, compared to the 2, 7% total cost of traditional wire transfers when accounting for fees, FX spreads, and intermediary charges. For institutional clients managing multi-currency treasury operations, the speed advantage, settlement in minutes rather than one to three business days, is often more compelling than the cost savings.
European EMIs built their businesses on exactly this kind of payment innovation. They can issue electronic money, hold client funds in safeguarded accounts, and process payments across the Single Euro Payments Area. Under MiCA, EMI authorization is the gateway for stablecoin issuance in Europe, e-money tokens can only be issued by credit institutions or EMIs. Zerohash secured both MiCA and EMI licenses in the Netherlands by May 2026, enabling it to handle both crypto assets and traditional electronic money flows across the European Economic Area. Stripe's stablecoin infrastructure platform Bridge obtained dual CASP and EMI authorization in Luxembourg in July 2026, creating a passportable framework across all 27 EU member states.
The problem is that this European licensing structure has no obvious analog in the U.S. federal framework now taking shape. The GENIUS Act and CLARITY Act both appear to assume that stablecoin custody and settlement will flow through entities supervised as banks, trust companies, broker-dealers, or federally qualified stablecoin issuers. An EMI licensed in Lithuania or Ireland may passport services across Europe, but that passport has no force in a U.S. regime built around OCC, FDIC, and SEC supervision.
The Senate bill remains uncertain, the ethics provision that Democrats have demanded still falls short of what Senators Gallego and Alsobrooks have said they require, and the August recess deadline is approaching. But the custody architecture is not the part of the bill under negotiation. Banking trade associations have focused their lobbying on tightening the prohibition on stablecoin yield, not on expanding the categories of institutions eligible to provide custody. The American Bankers Association released a statement on July 22 noting that the updated bill "still puts at risk the local lending that drives economic activity," but their concerns center on deposit flight, not on who can participate in settlement infrastructure.
For an EMI Head of Product watching this unfold, the strategic calculus is uncomfortable. Institutional clients seeking stablecoin treasury rails will look for settlement counterparties with clear U.S. regulatory standing. Neobanks and crypto-native firms with custody licenses, or partnerships with custody-licensed entities, can move immediately if the CLARITY Act passes. Traditional EMIs cannot. The question is not whether stablecoin settlement will become federally regulated, but whether your institution has any pathway into that regulated perimeter.
The multi-year timeline compounds the problem. An EMI that determines today it needs custody capabilities would face a licensing process that takes 6 to 12 months in the EU and broadly similar timelines at the FCA or other regulators, assuming the institution already has the operational infrastructure, compliance staff, and capital to support a custody application. By the time that process completes, the GENIUS Act's transition periods will have advanced, and the competitive window may have closed.
This is not a question of whether stablecoin settlement infrastructure is coming. That question was answered when Visa integrated USDC into its core settlement operations, when Mastercard acquired BVNK for $1.8 billion, when Stripe paid $1.1 billion for Bridge. The question is whether payment institutions built for fiat rails can adapt before their institutional client base makes its own choices about where to route treasury flows.
The Senate may or may not pass the CLARITY Act before the August recess. The ethics dispute may or may not resolve. But the custody framework that would govern stablecoin settlement is already written, in the GENIUS Act, in the OCC's proposed rules, in the FDIC's implementing guidance. For EMIs, the relevant fact is not what might change, but what has already been decided.
