The United States Securities and Exchange Commission (SEC) has begun to seriously consider how to accommodate continuous, around‑the‑clock trading—a model that has long been taken for granted in the cryptocurrency world. This development was highlighted during a briefing that took place on the same morning the agency announced its first formal approval of tokenized securities, signaling a broader shift in how regulators view digital assets and the markets that support them.
Historically, U.S. equity markets have adhered to a fixed schedule: trading opens at 9:30 a.m. Eastern Time and closes at 4:00 p.m., with after‑hours sessions offering limited liquidity.
The crypto ecosystem, by contrast, operates on a 24‑hour, seven‑day schedule, with exchanges around the globe constantly matching buyers and sellers. As digital assets become more intertwined with traditional finance, the SEC’s interest in extending the same nonstop accessibility to regulated securities reflects both a response to market demand and a proactive effort to prevent regulatory arbitrage. The briefing, which was attended by senior SEC officials, market participants, and industry observers, outlined several key considerations.
First, the agency must assess the technological infrastructure required to support nonstop trading while maintaining the integrity and security of the market. This includes robust surveillance systems capable of detecting manipulative behavior in real time, as well as resilient clearing and settlement mechanisms that can operate without the traditional overnight pause. Second, the SEC is evaluating the impact of continuous trading on market volatility. Crypto markets have demonstrated that price swings can be extreme when trading is uninterrupted, especially during periods of heightened news flow or macro‑economic uncertainty.
Regulators are therefore weighing whether similar volatility could emerge in tokenized securities or other digital‑linked assets, and what safeguards might be necessary to protect investors. Third, the agency is reviewing existing rules around market‑making, liquidity provision, and best execution. In a 24/7 environment, market makers would need to staff operations around the clock, potentially increasing costs.
The SEC is exploring whether existing exemptions and incentives for market makers can be adapted, or if new frameworks are required to ensure that liquidity remains sufficient without imposing undue burdens on participants. The simultaneous approval of tokenized securities—a first for the SEC—adds another layer of relevance. Tokenized securities are traditional financial instruments, such as stocks or bonds, that have been represented on a blockchain as digital tokens. By granting approval, the SEC signaled that it recognizes blockchain‑based representations as legitimate, provided they meet existing disclosure, registration, and investor‑protection standards.
This move also underscores the agency’s willingness to engage with emerging technologies rather than outright reject them. Industry analysts interpret the dual announcements as a coordinated strategy. By green‑lighting tokenized securities, the SEC creates a pathway for these assets to enter mainstream markets. By concurrently exploring nonstop trading, the agency prepares the regulatory scaffolding that would allow these digital securities to be bought and sold at any hour, mirroring the experience that crypto traders have come to expect.
The potential benefits of around‑the‑clock trading are significant. Investors would gain immediate access to price information and the ability to execute trades without waiting for the next market opening, which could improve price discovery and reduce the impact of after‑hours news shocks. For issuers, continuous trading could broaden the investor base, attracting participants from different time zones who previously faced logistical challenges. However, challenges remain.
Continuous operation raises questions about the adequacy of existing surveillance technology. Traditional market‑watch systems are calibrated for a defined trading day; extending them to 24/7 operation would require upgrades to handle a larger data volume and to flag suspicious activity in real time. Moreover, the settlement cycle—currently T+2 for most U.S. securities—might need to be rethought to accommodate faster, perhaps even instantaneous, settlement that blockchain platforms can provide.
Another concern is the human element. Regulators, compliance officers, and exchange staff are accustomed to a daily rhythm that includes a clear end‑of‑day cut‑off. Transitioning to a nonstop schedule would demand new staffing models, possibly involving shift work or automated oversight tools to ensure continuous compliance.
Internationally, several jurisdictions have already experimented with extended trading hours. European exchanges, for example, have introduced pre‑market and post‑market sessions, while some Asian markets have explored longer windows to align with global investors. The SEC’s contemplation of a truly round‑the‑clock model places the United States at the forefront of this regulatory evolution. In summary, the SEC’s recent activities illustrate a growing recognition that the traditional, time‑bounded structure of U.S.
securities markets may need to evolve to stay competitive in a digital age. By approving tokenized securities and simultaneously investigating the feasibility of 24/7 trading, the agency is laying the groundwork for a more integrated, flexible market that can serve both legacy investors and the burgeoning crypto community.
The coming months will likely see detailed proposals, stakeholder consultations, and perhaps pilot programs that test the practicalities of nonstop trading. If successful, the United States could set a new global standard, merging the reliability of regulated securities with the accessibility and speed that have made cryptocurrency markets so popular.
