SEC proposes transfer-agent rules that would let the official shareholder record sit on a blockchain

What changed

On September 1, 2026 the SEC proposed a rewrite of its transfer-agent rules and forms (Release No. 34-106246, File No. S7-2026-30). It appeared in the Federal Register on September 4, 2026, and comments are due November 3, 2026. Three parts bear on tokenized securities. First, amended Rule 17ad-9(b) would require the master securityholder file, the official list of record owners, to be electronic, and would let it span linked files or systems of the agent's choosing, provided the agent keeps exclusive control of the file at all times. The release says this would permit a blockchain or other distributed ledger to serve as the file or part of it, but would not require one. Second, Form TA-2 would ask each registered agent to count issues whose master file used distributed ledger technology, to name its tokenization agents and ledger platforms, and to report issues serviced by tokenization model, issuer-sponsored or third-party-sponsored, by security type as of December 31. Third, new Rule 17ad-31 would bar an agent from recording an unregistered issuance, a legend or stop-order removal, or an insider transfer unless it has a reasonable basis to believe the trade does not violate Securities Act Section 5(a); an independent counsel opinion or the agent's own exemption analysis would give a safe harbor if no red flags appear. Rule 17ad-31 applies to all securities, token or not. None of this is in force.

Who it affects

• SEC-registered transfer agents that keep, or plan to keep, shareholder records on a blockchain
• Issuers and fund sponsors that tokenize their own shares, and third parties that tokenize others' securities
• Tokenization agents and ledger platforms that would be named on Form TA-2
• Investment advisers doing due diligence on tokenized funds and securities for client accounts

What is still open

• Whether the Commission adopts the proposal after the November 3, 2026 comment deadline, and in what form
• What 'exclusive control' of a master file requires when records sit on a public blockchain the agent does not run; the release asks this in request for comment 84
• How on-chain wallet records would be tied to off-chain holder identity so that a token transfer changes the official record
• Whether the issuer-sponsored versus third-party-sponsored split on Form TA-2 survives, and how agents classify hybrid models

What it means for an advisor

• For each tokenized holding, ask which registered transfer agent keeps the official record and whether that agent, not the token contract or a vendor, controls it
• Record whether a tokenized product is issuer-sponsored or third-party-sponsored; the proposal uses the same split the SEC staff drew in January 2026
• Do not treat the proposal as current law; existing transfer-agent rules still govern until the Commission adopts final rules
