Stablecoin tokens over a federal rulemaking document with an October 23 deadline stamp

Stablecoin issuers just got seven more weeks to shape the first customer identification program rules ever written for their industry. FinCEN and the federal banking agencies extended the public comment period on the proposed CIP requirements for permitted payment stablecoin issuers to October 23, 2026, pushing back the original August 21 deadline that closed the initial window under the GENIUS Act rulemaking.

The joint proposal, issued in June by FinCEN, the OCC, the Federal Reserve Board, the FDIC, and the NCUA, treats permitted payment stablecoin issuers as financial institutions for Bank Secrecy Act purposes. It is the most consequential identity rulemaking in crypto to date, and the extension signals both the volume of comments received and the complexity of the questions still open. For compliance teams, the extension is not a pause. It is a planning window with a countdown attached.

What the proposed CIP rule covers

The proposal requires each permitted payment stablecoin issuer to establish a written customer identification program scaled to its size and business model. Before opening an account, issuers must collect a customer's name, date of birth or date of formation, address, and identification number, then verify identity through risk-based documentary or non-documentary procedures.

The rule also carries the standard banking-grade obligations: five-year record retention for all CIP information, screening against government terrorist watchlists, customer notice that identity will be verified, and an option to rely on the CIP of another federally regulated financial institution. None of this is exotic for a bank. All of it is new for an issuer whose onboarding flow was designed around a wallet address.

Why the window moved

Comment extensions usually mean one of two things: heavy industry response or unresolved definitional problems. This rulemaking has both. Issuers, exchanges, and trade groups filed extensively before the August deadline, with recurring disputes over how far verification obligations should follow a token after issuance. The proposal currently draws the line at the primary market: CIP obligations attach to the direct relationship between issuer and customer, not to secondary market transfers between third parties.

The line between primary and secondary markets

The primary-market limitation is the single most important design decision in the proposal. An issuer must verify the institutional trader redeeming tokens directly, but not every wallet that touches the token afterward. Critics argue that leaves the secondary market as an anonymity refuge; supporters answer that extending CIP to peer transfers would be unworkable and push activity offshore. Wherever the final rule lands, issuers will need verification infrastructure that can scale in either direction.

The compliance clock behind the deadline

The proposal sets compliance at 12 months after the final rule is issued. A final rule in early 2027 means live CIP programs in early 2028, with vendor selection, integration, and testing all inside that window. That is where automation earns its keep. deepidv's Luna compliance agent tracks the rulemaking docket, maps each proposed requirement against an issuer's existing onboarding flow, and flags the gaps while they are still design choices. Paired with the core verification platform, issuers can run bank-grade CIP collection and verification inside a single session, including watchlist screening and the five-year evidence trail the rule demands.

Stablecoin CIP FAQ

What is the new comment deadline for the stablecoin CIP rule?
The extended comment period runs to October 23, 2026. The original deadline was August 21, 2026, set when the joint proposal was published in June. Comments can be filed with FinCEN and the banking agencies through the Federal Register docket.
Which agencies are behind the stablecoin CIP proposal?
Five agencies issued the joint proposal: FinCEN, the Office of the Comptroller of the Currency, the Federal Reserve Board, the FDIC, and the NCUA. The rulemaking implements the GENIUS Act, which directs that permitted payment stablecoin issuers be treated as financial institutions under the Bank Secrecy Act.
Do stablecoin CIP rules apply to secondary market transactions?
Under the current proposal, no. CIP obligations apply only to the primary market, meaning direct relationships between the issuer and its customers. Secondary market transfers between third parties are outside scope, though commenters have asked the agencies to revisit that boundary.
How can stablecoin issuers comment on the proposed CIP rule?
Comments are filed through the Federal Register docket for the joint proposal, referencing the agencies' rulemaking identifiers, before the extended October 23, 2026 deadline. Issuers typically pair a comment letter with an internal gap assessment.
When would stablecoin issuers have to comply?
The proposal gives issuers 12 months from the date the final rule is issued. With the comment period now closing October 23, 2026, a final rule in 2027 would put mandatory compliance in the 2028 timeframe.
