The United States is building two regulatory architectures for stablecoins at once, and they are starting to collide. On one side, the GENIUS Act framework is creating a pathway for federally supervised stablecoin issuers, with a January 18, 2027, effective date that will make it illegal to issue a payment stablecoin in the United States without an appropriate federal or approved state license. On the other side, the Independent Community Bankers of America is suing the Office of the Comptroller of the Currency to shut down the very charter pathway that most crypto firms plan to use to enter that framework. Into this collision steps Rain, a New York-based stablecoin payments company that filed an application on October 5 to establish Rain National Trust Bank – the latest entrant in a flood of crypto firms seeking OCC national trust bank charters.
Rain’s application, prepared with Paul Hastings, proposes a separately capitalized subsidiary supervised and examined by the OCC. The bank would handle three functions: fiduciary custody of digital assets and U.S. dollars, reserve management for permitted stablecoin issuers, and issuance and redemption of U.S. dollar-backed stablecoins for institutional clients. Brandon Soto, formerly of Square Financial Services and Coastal Financial Corporation, has been named proposed president and CEO. The entity would be an uninsured national trust bank – no deposits, no consumer accounts, no commercial loans. It is a narrow, purpose-built vehicle designed to sit at the intersection of stablecoin infrastructure and institutional custody.
The filing lands in a regulatory environment that is simultaneously opening and closing. The GENIUS Act, enacted in July 2025, creates a new category – the Federal Qualified Payment Stablecoin Issuer (QPSI) – and grants the OCC exclusive authority to license, regulate, and supervise these entities. The statute mandates one-to-one reserve backing in cash, deposits, or short-term U.S. Treasuries, with monthly attestations certified by issuer executives. It prohibits paying interest or yield to stablecoin holders, with a rebuttable presumption against indirect yield through affiliates. Beginning January 18, 2027, no person may issue a payment stablecoin in the United States without an appropriate license.
The OCC has been processing applications at speed. Under the current administration, the agency has approved or conditionally approved 21 national trust bank charters, including 13 for cryptocurrency companies such as Coinbase, Circle, World Liberty Financial, and Protego Holdings. The March 2026 final rule on national bank chartering, along with Interpretive Letter 1176, established the legal framework for these approvals. For crypto firms, the trust charter is not merely a regulatory checkbox – it is the gateway to the GENIUS Act’s QPSI licensing, which will be the only legal pathway for stablecoin issuance after the January 2027 effective date.
The community banking lobby is trying to close that gate. On October 2, 2026, the ICBA filed suit against the OCC and Comptroller Jonathan Gould in the U.S. District Court for the District of Columbia, arguing that the agency has exceeded its statutory authority under the National Bank Act. The complaint contends that Congress authorized only three categories of national banks – traditional depository banks, bankers’ banks, and national trust banks exercising fiduciary powers – and that the OCC has unlawfully created a fourth category of non-depository, non-fiduciary national trust banks for crypto firms. ICBA President and CEO Rebeca Romero Rainey stated: “The OCC’s decision to allow companies to obtain national trust bank charters to conduct substantial non-fiduciary activities exceeds the authority Congress granted the agency. Congress did not create the national trust charter as a side door into the banking system for crypto firms.”
The lawsuit seeks to vacate the March 2026 final rule and Interpretive Letter 1176, prohibit the OCC from using the rule to grant further trust charters to non-fiduciary entities, and rescind Protego Holdings’ conditional charter approval. If successful, it would not merely slow the pipeline – it would retroactively unwind the legal basis for every crypto trust charter the OCC has granted since early 2026. The OCC declined to comment on pending litigation.
This creates a structural tension that Rain’s filing embodies. The company is a Visa and Mastercard Principal Member with enterprise-grade infrastructure for stablecoin payments across cards, wallets, and global money movement. Its application is designed to fit squarely within the GENIUS Act framework – the same framework the Fed is building through parallel NPRMs with a November 30 comment deadline and a January 2027 effective date. But the legal foundation for the charter pathway Rain is using is the same foundation the ICBA is trying to demolish.
The timing is revealing. Rain filed four days before the ICBA lawsuit became public knowledge and three days after it was filed. The application was in preparation before the lawsuit landed, which suggests that crypto firms are not waiting for the legal uncertainty to resolve – they are filing now and expecting the regulatory framework to hold. This is a bet on institutional momentum over legal challenge. The Bank of North Dakota’s Roughrider Coin pilot, launched the same week, represents a different pathway – a state-bank-affiliated stablecoin entering the GENIUS Act window through state charter rather than federal trust charter. Both filings are responses to the same deadline, but they test different assumptions about which legal pathway will survive.
The deeper question is whether the OCC’s trust charter pathway is a legitimate regulatory innovation or an end run around congressional intent. The ICBA’s argument is structurally coherent: if Congress intended the national trust charter for fiduciary activities, then using it as a platform for stablecoin issuance – which is not a fiduciary function – stretches the statute beyond recognition. But the GENIUS Act itself implicitly assumes that non-bank entities will be able to obtain OCC supervision, which suggests that Congress anticipated exactly this kind of entrant. The lawsuit is less about legal theory than about market structure: who gets to issue stablecoins in the United States, and whether the answer includes crypto-native firms or is reserved for traditional banks.
