The Office of the Comptroller of the Currency published its GENIUS Act implementation proposal in the Federal Register on March 2, 2026 — a 376-page proposed rule, announced in OCC Bulletin 2026-3, that would govern how national banks issue payment stablecoins, custody them, and manage tokenized-asset holdings. The proposal translates the 2025 stablecoin statute into bank-supervision practice: definitions for insured depository institutions and national banks, permitted activities, reserve requirements, and a 'control' standard for custodians of tokenized assets.

What does the proposal cover?
Four building blocks. Issuance: which OCC-chartered institutions may issue payment stablecoins and under what capital and liquidity treatment. Reserves: what backing qualifies — the statute's high-quality liquid assets — and the custody standards for the reserve portfolios. Permitted activities: a schedule of what national banks and their subsidiaries may do in the stablecoin and tokenization stack. And the control standard: the most-analyzed line in the document, defining when a custodian of tokenized assets exercises control that triggers regulatory treatment — a definition with consequences far beyond stablecoins, since tokenized deposits and funds pass through the same language.
The proposal follows the OCC's February final rule permitting national trust banks to offer stablecoin custody and issuance services — February's action opened the charter door; March's proposal writes the rulebook behind it.
Why does a banking rule matter to crypto markets?
Because it builds the on-ramp. The GENIUS Act's statutory framework set the destination — payment stablecoins as regulated instruments with certified reserves — but statute does not issue a charter or schedule an exam. The OCC's rulemaking is where the framework becomes an operational path for banks, and bank participation is the difference between stablecoins as a crypto-market instrument and stablecoins as payment infrastructure. Industry comment letters — including the Bank Policy Institute's call for interagency coordination — show large banks engaging on the details, which is itself a signal about intended participation.
The sequencing across agencies also matters. Treasury's implementation work, the Fed's role in payments supervision, and state regimes for non-bank issuers all parallel the OCC track; a national-bank pathway that goes live first would pull issuance activity toward federal charters, reshaping where the stablecoin industry's operators sit.
What is the angle other coverage skipped?
The comment period as the real event. A 376-page proposal lands with its economics unwritten: the cost of reserve custody requirements, the operational burden of the control standard, the competitive position of banks versus state-regulated non-bank issuers — all of it negotiable until comments close and the final rule lands. The comment letters filed by banks and industry groups are therefore the primary source to watch, more informative than the proposal's own text about how the rule will look when it binds.
The second angle is the tokenization tail. The control standard for custodians of tokenized assets — flagged across law-firm analyses as the document's most consequential definition — reaches past stablecoins into tokenized funds, deposits and securities custody. Banks reading the proposal are pricing a tokenized-asset future, not just a stablecoin present.
What should readers watch?
The Federal Register docket for comment filings, the OCC's bulletin page for the final rule's timing, and parallel tracks — the Fed and FDIC's interagency posture, and the state regimes certifying non-bank issuers. For market participants, the actionable milestones are charter applications under the February trust-bank rule and the first reserve examinations once the framework binds.
