Blockchain Now in SEC Rulebook

On 9/1/2026 the SEC Proposed the First Substantive Rewrite of its Transfer Agent Rules, since the late 1970s and early 1980s, naming Blockchain Explicitly rather than Leaving the Mmarket to infer where Distributed Ledgers Fit. Transfer Agents are the Roughly 273 Registered Firms that maintain the Official Record of Who owns a Company’s Securities, Process Transfers and Handle Dividends, which is about as Uunglamorous as Financial Infrastructure gets. To put the Timing in Perspective, Commissioners Aguilar and Gallagher Publicly called these Rules Anachronistic and Overdue for Reform in 2015, so this has taken Eleven years from the Point where Two Sitting Commissioners said Out-Loud that the Framework no longer Matched the Industry.

Most of the proposal is housekeeping. Registration would become effective in 45 days rather than 30, retention requirements get consolidated, processing standards get aligned with the current settlement cycle, and the threshold that triggers limits on a transfer agent expanding its business rises from 75% to 95%. The load-bearing part is the terminology, updated throughout to recognize electronic and blockchain-based recordkeeping, because that changes what an agent may treat as the official record. Proposed Rule 17ad-31 on restrictive legends matters for the same reason, since in a tokenized context the restriction could be enforced by a smart contract rather than by a person checking a document. Safeguards come attached, with stronger requirements on cybersecurity, data integrity, operational risk, compliance and business continuity.

This is now the third time this year a regulator has extended existing obligations to the new technology rather than writing a separate rulebook for it, after the Fed confirmed capital treatment for tokenized securities in March and the ECB accepted them as Eurosystem collateral at the end of the same month. That is the outcome the industry should want, even though it is more work than a bespoke regime.

The qualification is that this is a proposal, not a rule. The comment period runs 60 days from Federal Register publication, after which the Commission reviews comments and votes on a final version, and proposals change materially between those points. The SEC is also asking for input on questions it has not answered, including how digital wallets should be treated, how onchain fraud risk should be handled and how ownership records ought to interact with distributed ledgers. Anyone reading this as a finished framework is reading it wrong.

Still, the argument has moved. Two years ago the question was whether a blockchain could serve as an official ownership record at all, and the answer arrived through enforcement actions rather than rulemaking. The question now is how it should be done and what controls come with it. The separate roundtable the SEC has scheduled for September 17 on round-the-clock trading, with NYSE, Nasdaq, DTCC, State Street, Citadel Securities, Cboe and Robinhood attending, means the ownership record and the trading day are being examined in the same season by the same regulator. For anyone building in tokenized stocks, funds or depositary receipts, the record layer is no longer the unresolved question it was in January. The unresolved questions have moved downstream, which is where the comment file is pointed.
