TLDR
The SEC is moving to modernize securities rules for blockchain-based records while exploring 24/7 stock trading with major Wall Street firms.
- The regulator has proposed updated transfer-agent rules that explicitly allow blockchain-based share registries and tokenized securities under regulated oversight.
- The SEC will host a September roundtable with BlackRock, Nasdaq, NYSE and others to discuss moving U.S. stocks toward all-hours, continuous trading.
- For crypto users, this points to a gradual convergence between tokenized TradFi assets and crypto markets, with new liquidity, correlation and regulatory risks to watch.
Deep Dive
1. SEC Blockchain Rule Overhaul
The SEC has proposed a major update to decades-old transfer-agent rules so that public blockchains and other distributed ledgers can legally serve as official shareholder records, under the control of registered transfer agents. This would let tokenized securities sit inside the same legal ownership system as traditional stocks, replacing paper-centric rules with electronic and onchain records, while keeping responsibility with regulated intermediaries that maintain the master securityholder file and report to the SEC.
The proposal would modernize record-retention, risk-management and compliance obligations for transfer agents using blockchain systems, and require firms to report which tokenized securities and distributed-ledger platforms they service, according to coverage of the SECs transfer agent rules for blockchain-based share records and a broader overhaul of 50-year-old Wall Street rules. The rules are proposed, not yet final, and enter a 60-day public comment period.
Tokenized stocks and bonds could increasingly be treated as real securities in the U.S. system, but only when their onchain records are managed by regulated transfer agents that meet strict safeguards.
2. Plan For All-Hours Trading
Alongside the blockchain overhaul, the SEC is convening a high-profile public roundtable on September 17 to examine enabling 24/7 trading in U.S. stocks. Participants include BlackRock, Nasdaq, NYSE, Citadel Securities, Robinhood, DTCC and other major TradFi firms, as reported in a public roundtable on 24/7 trading and summarized in articles on the SECs sweeping reform of blockchain infrastructure and 24/7 trading plans.
The agenda covers continuous settlement, overnight supervision, instant clearing systems and investor protections outside regular hours. In effect, the SEC is asking how U.S. equities could operate more like crypto markets, which already trade 24/7, while managing risks such as thinner overnight liquidity and wider spreads. The roundtable itself is exploratory, not a binding rule change, but it is a clear signal that regulators are actively considering all-hours equity trading.
3. Implications For Crypto Users
For crypto, these moves narrow the gap between onchain finance and regulated TradFi. If tokenized securities become mainstream under the new transfer-agent framework, they would trade and settle using blockchain infrastructure, potentially alongside crypto assets on the same rails. And if U.S. stocks move toward all-hours trading, traditional assets could start reacting in real time to macro events the way Bitcoin and other coins already do, increasing cross-market correlation.
Institutional players already involved in tokenization and crypto, such as DTCC and large asset managers, are watching these SEC initiatives closely, as highlighted in coverage of SEC blockchain reforms tied to major institutions. For crypto users, the opportunity is more integrated portfolios and new products (tokenized equities, onchain perps, 24/7 ETFs), but also more complex regulatory rules and potential spillover from equity volatility into digital assets.
Confidence: high because multiple independent reports describe the same SEC proposals and roundtable using consistent dates and participant lists.
Conclusion
The SECs twin focus on modernizing transfer-agent rules for blockchain-based records and exploring all-hours stock trading signals a structural shift in how regulated markets may adopt crypto-native infrastructure and trading patterns. If these proposals advance, tokenized securities and 24/7 equities could make traditional assets behave more like crypto, blurring boundaries between the two. For now, nothing is final, but this is an important early stage in the long-term convergence of TradFi and digital asset markets.
