SEC sets Sept. 17 roundtable on 24-hour U.S. trading and proposes blockchain-aware transfer-agent
A separate proposal would let transfer agents use blockchains as official records and weighs wallet addresses as identifiers.
The U.S. Securities and Exchange Commission is running two market-structure tracks that intersect with crypto: a Sept. 17 roundtable on preparations for 24-hour U.S. securities trading and a proposed overhaul of transfer-agent rules that explicitly contemplates blockchain recordkeeping. The transfer-agent proposal opens a 60-day public comment period and raises a live design question for tokenized securities: whether holder records can rely on digital-wallet identifiers instead of physical addresses.
SEC Puts 24-Hour U.S. Trading on the Table for Sept. 17—With DTCC, NYSE, Nasdaq and Citadel in the Room
The Securities and Exchange Commission has scheduled a Sept. 17 roundtable at its Washington headquarters to explore what it would take for U.S. securities markets to operate on a 24-hour basis, and it has published both the agenda and a roster that reads like a cross-section of the plumbing that would have to hold up under continuous hours.
The participant list includes the New York Stock Exchange, Nasdaq, State Street, Citadel Securities, Cboe, the Depository Trust & Clearing Corporation, and Robinhood, among others. That mix matters because 24-hour trading is not just an exchange-hours decision. It forces alignment across venues, market makers, custodians, and post-trade infrastructure that currently coordinate around a defined close.
The agenda topics signal where the Commission expects friction. Panels are set to cover overnight surveillance, closing-price practices, and the clearing and settling of trades, alongside operational mechanics such as how system maintenance would work in a continuous environment. For crypto traders, the immediate relevance is less about whether equities “go 24/7” and more about whether the Commission uses this process to standardize surveillance, closing-price formation, and post-trade constraints in ways that spill into crypto broker-dealers operating in securities contexts.
Transfer-Agent Proposal Explicitly Brings Blockchain Records—and Wallet Identifiers—Into the Rulebook
Earlier the same day, the SEC proposed a rule to modernize regulations for registered transfer agents, explicitly updating the framework to account for “electronic communications and blockchain technology” in connection with securities offerings and the transfer of shares, according to SEC Chairman Paul Atkins. Transfer agents are the regulated firms that maintain the official record of who owns a security and process changes in ownership, which is exactly the layer tokenized securities try to compress by moving issuance and transfers onto a blockchain.
Mechanically, the proposal would allow the use of blockchains as official records of transactions, reducing ambiguity around whether an onchain ledger can satisfy a core compliance function in the securities stack. The tradeoff is that the proposal also adds new controls on transfer agents’ operations, including in cybersecurity-related areas, which is where “blockchain as a record” stops being a conceptual question and becomes an operational one.
Commissioner Hester Peirce put a finer point on the identity problem tokenized securities keep running into: “Should transfer agents continue to be required to collect names and physical addresses of securityholders or should the rule allow other identifiers, such as email and digital wallet addresses, to be collected instead?” The proposal is open for a 60-day public comment period, and the packet does not specify the exact closing date, so the rule is not final and could change materially based on feedback.
One industry linkage sits in the background as these rules move: Bullish, the parent company of CoinDesk, recently acquired transfer agent Equiniti in a $4.2 billion deal. That does not change the SEC’s process, but it is a reminder that transfer-agent infrastructure is becoming a strategic asset as tokenization pushes recordkeeping and settlement closer together.
My Read: This Is a Quiet Green Light for Tokenized Securities Plumbing, Not a Finished Rule
The filing is being read in some corners as the SEC “embracing tokenization,” and that overstates what has actually happened. What the Commission has done is run two parallel processes that intersect with crypto, one testing continuous-trading mechanics and another tightening the official ownership-record layer where tokenized securities would have to live, and the real test is whether the comment record and any follow-on amendments keep blockchain records and wallet identifiers inside the compliant path rather than treating them as edge cases.
The threshold that matters is procedural: Sept. 17 needs to produce concrete constraints around overnight surveillance, closing-price practices, and clearing and settlement, while the 60-day transfer-agent comment window needs to surface whether market infrastructure firms push for blockchain-as-official-records and wallet-address identifiers or try to narrow them back to legacy data fields. If the SEC comes out of both tracks with operational-control requirements that are workable for onchain systems, tokenized securities stop being a narrative and start looking like a buildable compliance stack.
