The U.S. Securities and Exchange Commission (SEC) is convening a roundtable to examine the prospects and implications of 24-hour trading, reflecting a broader shift toward “always-on” finance. The initiative underscores growing interest in continuous market access across asset classes, including digital assets, and the operational, regulatory, and investor-protection considerations that come with it.
Why it matters
- Market structure is evolving: Crypto assets trade around the clock, and some venues in traditional finance have begun testing extended or overnight sessions. A move toward continuous trading would be a significant change for U.S. securities markets.
- Investor access and risk: Expanded hours could increase access and flexibility for investors but may also introduce new risks related to liquidity, price discovery, and volatility outside regular sessions.
- Operational readiness: Around-the-clock trading raises questions about market surveillance, clearing and settlement, systems resiliency, and staffing across exchanges, brokers, and clearinghouses.
Key topics likely to be discussed
- Liquidity and volatility: How spreads, depth, and price formation behave in low‑liquidity windows; potential impacts on retail investors and institutional strategies.
- Market surveillance and fair access: Monitoring manipulation and misconduct across continuous sessions, and ensuring fair, orderly markets.
- Clearing and settlement: Interactions with the U.S. move to T+1 settlement and the feasibility of real-time or near‑real‑time processes in an always-on environment.
- Corporate actions and disclosure timing: Coordination of earnings releases, material disclosures, and trading halts when markets do not close.
- Systems resiliency and cybersecurity: Meeting uptime and recovery standards for exchanges and alternative trading systems operating continuously.
- Best execution and investor protection: Broker obligations, order routing, and safeguarding retail investors during extended hours.
Market backdrop
U.S. equities currently trade during a regular session with pre‑market and after‑hours periods, while some alternative trading systems have introduced limited overnight access. Futures and foreign exchange markets operate with near‑continuous schedules on business days, and crypto markets trade 24/7 globally. The SEC’s roundtable signals a closer look at whether and how U.S. securities market rules and infrastructure might adapt to these trends.
What to watch
- Details on the roundtable’s timing, participants, and agenda from the SEC.
- Input from exchanges, brokers, asset managers, clearing agencies, and investor advocates on costs, benefits, and safeguards.
- Any follow‑on requests for comment, pilot programs, or rulemaking the agency may consider after the discussion.
