U.S. SEC Starts Planning for 24/7 Trading, a Standard Practice in Crypto Markets

The United States Securities and Exchange Commission (SEC) has begun to explore the logistics and regulatory framework needed to support round‑the‑clock trading of securities, a concept that has long been taken for granted in the cryptocurrency world. While traditional equity markets in the United States operate on a fixed schedule—typically from 9:30 a.m.

to 4:00 p.m. Eastern time, Monday through Friday—the digital asset sector has been accustomed to continuous, 24‑hour, seven‑day‑a‑week trading.

This cultural difference has highlighted a growing tension between legacy financial infrastructure and the emerging, technology‑driven markets that operate without the constraints of conventional exchange hours. The SEC’s interest in around‑the‑clock trading surfaced during a high‑profile event that coincided with the agency’s approval of the first tokenized securities offerings. Tokenization, which involves converting a traditional financial instrument—such as a stock, bond, or real‑estate interest—into a digital token on a blockchain, promises to increase liquidity, lower transaction costs, and broaden access for investors worldwide. By granting conditional approval for these tokenized securities, the SEC signaled that it is willing to engage with innovative financial products, provided that investor protections and market integrity are upheld.

During the same session, senior SEC officials outlined a series of preliminary steps that would be required to transition certain market segments to a continuous‑trading model. These steps include: 1. **Regulatory Clarification** – Drafting clear rules that define which securities can be traded nonstop, how price discovery will function outside traditional market hours, and what reporting obligations will apply to participants. 2.

**Technology Standards** – Establishing robust technical standards for the platforms that will host 24/7 trading, ensuring they can handle high‑frequency data feeds, maintain cybersecurity safeguards, and provide reliable settlement mechanisms. 3.

**Market Surveillance** – Developing advanced monitoring tools capable of detecting manipulation, insider trading, or other illicit activities in a market that never sleeps. Continuous surveillance will be essential to preserve investor confidence.

4. **Liquidity Management** – Addressing the challenge of maintaining sufficient liquidity when traditional market makers may not be active.

The SEC is considering mechanisms such as designated liquidity providers, automated market makers, or cross‑venue liquidity pools to keep bid‑ask spreads tight. 5. **International Coordination** – Aligning U.S.

rules with those of other jurisdictions, many of which already permit extended trading sessions or have begun experimenting with 24‑hour markets for certain asset classes. Cooperation will help prevent regulatory arbitrage and ensure consistent enforcement.

The move toward nonstop trading is not merely a technical upgrade; it reflects a broader shift in investor expectations. Modern traders, especially those who are active in crypto, have grown accustomed to instant execution, real‑time price updates, and the ability to react to global events at any hour. For instance, a geopolitical development in Europe or an economic data release in Asia can now influence market sentiment instantly, and participants expect the ability to act on that information without waiting for the next U.S.

market open. Critics, however, caution that extending trading hours could introduce new risks.

Market volatility may increase when liquidity is thinner, potentially leading to larger price swings. Moreover, the continuous flow of information could exacerbate information asymmetry, giving sophisticated algorithmic traders an edge over retail investors who may lack the tools to monitor markets around the clock. To mitigate these concerns, the SEC is exploring a phased approach. Initially, it may permit 24/7 trading for a limited set of tokenized securities that meet strict eligibility criteria, such as high market capitalization, transparent governance, and robust custody solutions.

Over time, as the regulatory framework matures and data on market performance accumulates, the scope could be broadened to include a wider array of assets, potentially even traditional equities. The approval of tokenized securities on the same day as the round‑the‑clock trading discussion underscores a strategic alignment within the SEC.

By acknowledging the legitimacy of blockchain‑based securities and simultaneously addressing the operational realities of a continuously open market, the agency is positioning itself at the forefront of financial innovation. This dual focus aims to protect investors while fostering an environment where new technologies can thrive. Industry participants have responded positively to the SEC’s signals.

Exchanges that specialize in digital assets are already preparing infrastructure upgrades to support nonstop trading, including enhanced order‑matching engines and real‑time settlement layers that leverage distributed ledger technology. Asset managers are evaluating how tokenized holdings can be integrated into existing portfolios, offering clients exposure to previously illiquid assets with the added benefit of immediate tradability. Looking ahead, the SEC’s initiative may serve as a catalyst for broader reforms across the U.S. financial system.

If successful, it could prompt traditional exchanges to reconsider their own trading schedules, perhaps adopting extended hours or hybrid models that blend conventional and blockchain‑based mechanisms. Such evolution would bring U.S.

markets more in line with global peers, many of which already operate multi‑session trading windows for commodities, foreign exchange, and certain derivatives. In summary, the Securities and Exchange Commission is actively laying the groundwork for a future where securities can be bought and sold at any time of day, mirroring the seamless experience that crypto traders have come to expect.

By coupling this ambition with the recent green light for tokenized securities, the agency is signaling a willingness to adapt its regulatory approach to the realities of a digital, borderless economy. The path forward will involve careful rulemaking, technological upgrades, and ongoing dialogue with market participants, but the potential payoff—a more efficient, inclusive, and resilient capital market—could be substantial.
