U.S. SEC begins prepping for around-the-clock trading that crypto treats as the norm
The U.S. Securities and Exchange Commission has begun formal preparations to address around-the-clock trading — an operating cadence long accepted in crypto markets — convening an event to dig into the implications on the same morning it approved tokenized securities. The dual moves signal a regulatory recognition that continuous trading and blockchain-native settlement models are becoming central issues for market structure and oversight.
What the SEC examined: market hours, settlement and market structure
Traditional U.S. securities markets operate on fixed hours with well-established clearing and settlement processes, but digital-asset trading typically runs 24/7. The SEC’s recent event focused on how that divergence affects price discovery, liquidity provision and the technical underpinnings of post-trade processing. Approval of tokenized securities the same day underscores a practical bridge between regulated securities and blockchain-based settlement, raising questions about how continuous trading could be reconciled with existing rules on trade reporting, custody and investor protections.
From a market-structure perspective, continuous trading alters the roles and economics of market makers and exchanges. Venues and brokers that currently manage risk and capital around discrete trading sessions would need to build infrastructure for constant order flow, automated risk controls, and extended operational staffing. Settlement finality native to many blockchains could compress or eliminate traditional settlement windows, but it also places new demands on interoperability between on-chain records and off-chain regulatory reporting.
Implications for institutions, liquidity and oversight
For institutional participants, 24/7 trading combined with tokenized securities presents both opportunities and challenges. Continuous markets can improve access and enable intraday rebalancing across time zones, potentially increasing liquidity for major digital assets such as Bitcoin and Ether as well as for tokenized securities. At the same time, institutions will need robust custody, hot/cold key management, and liquidity risk frameworks to operate securely around the clock. Custodians, prime brokers and clearing agents may face pressure to extend services beyond traditional business hours or to provide guaranteed settlement windows backed by on-chain mechanisms.
Regulators will have to contend with surveillance and enforcement across a nonstop market environment. Tools used to detect manipulation, enforce disclosure and implement circuit breakers in U.S. equity markets were designed for set trading windows; adapting them to continuous trading will require new technical capabilities and possible changes in rules. Stablecoins and other settlement mediums may become more integral as instant, reliable on-chain settlement becomes a linchpin for continuous trading of tokenized assets.
The SEC’s simultaneous approval of tokenized securities highlights a potential future in which securities can exist natively on distributed ledgers and, subject to regulation, trade more like digital assets. That convergence raises operational questions about recordkeeping, reconciliation, and the roles of exchanges, transfer agents and custodians in a hybrid on-chain/off-chain environment.
Market participants will likely watch for follow-up signals from the SEC and other regulators, including formal rulemaking, guidance on custody and settlement of tokenized securities, pilot programs for extended hours trading, and coordination with self-regulatory organizations. Exchanges, custodians and institutional investors will also be monitoring technical standards for on-chain settlement, surveillance technologies suitable for 24/7 markets, and how liquidity provision evolves for Bitcoin, Ether and newly tokenized securities.
