U.S. SEC Starts Planning for Continuous Trading, a Practice Common in Crypto Markets

The United States Securities and Exchange Commission (SEC) has recently turned its attention to a concept that has become almost second nature in the digital‑asset world: trading that never stops. While traditional equity markets in the United States operate on a set schedule—typically opening at 9:30 a.m. Eastern Time and closing at 4:00 p.m.

on weekdays—many cryptocurrency exchanges have long offered investors the ability to buy and sell assets at any hour, any day of the year. Recognizing the growing importance of this model, the SEC convened a special meeting to explore how a continuous‑trading framework could be integrated into the existing regulatory structure for securities. ### Why the SEC Is Considering 24/7 Trading The push toward round‑the‑clock trading is driven by several intersecting forces.

First, the market for tokenized securities—digital representations of traditional financial instruments such as stocks, bonds, or real‑estate interests—has expanded dramatically over the past few years. These tokens are built on blockchain technology, which inherently operates without the constraints of a physical exchange floor or a fixed timetable. As more issuers and investors adopt tokenized forms, the demand for a trading environment that mirrors the always‑on nature of the underlying blockchain grows. Second, the investor base for digital assets is increasingly global.

A trader in Tokyo, a fund manager in London, and a retail investor in São Paulo may all wish to transact in the same security within the same 24‑hour period. A traditional market schedule creates friction for these participants, potentially driving liquidity away from U.S.

venues toward overseas platforms that already support nonstop trading. Third, the SEC’s own mandate to protect investors and maintain fair, orderly markets compels it to keep pace with technological innovation. By studying continuous trading, the agency hopes to pre‑empt potential regulatory gaps that could be exploited by bad actors, such as market manipulators who might take advantage of after‑hours price gaps or limited oversight. ### The Context of Tokenized Securities Approval The timing of the SEC’s discussion is noteworthy because it coincided with the agency’s formal approval of a set of tokenized securities.

This approval marked a significant regulatory milestone, signaling that the Commission is willing to recognize blockchain‑based representations of traditional assets as legitimate securities, provided they meet existing disclosure, registration, and investor‑protection standards. By pairing the tokenized‑securities approval with a conversation about nonstop trading, the SEC effectively signaled a broader strategic vision: not only will digital tokens be treated as securities under the law, but the mechanisms for trading those securities may also evolve to reflect the digital environment in which they live. This dual approach could help bridge the gap between legacy financial infrastructure and the emerging decentralized finance (DeFi) ecosystem. ### Potential Benefits of Around‑the‑Clock Trading 1.

**Improved Liquidity**: Continuous trading can reduce the disparity between supply and demand that often emerges at the close of a traditional market session. With more opportunities for price discovery, bid‑ask spreads may narrow, benefiting both buyers and sellers. 2.

**Enhanced Price Transparency**: When markets are open 24/7, price information is updated in real time, allowing investors to make more informed decisions based on the latest data rather than relying on stale end‑of‑day quotes. 3.

**Greater Market Access**: Retail and institutional participants in different time zones can trade during their normal business hours, fostering a more inclusive market that better reflects the global nature of capital flows. 4.

**Alignment with Underlying Technology**: Since blockchain networks operate continuously, aligning the trading schedule with the technology eliminates artificial bottlenecks and reduces the need for complex workarounds, such as after‑hours order queues. ### Challenges and Regulatory Concerns Despite the apparent advantages, several challenges must be addressed before the SEC can endorse a full‑scale shift to nonstop trading for securities: - **Surveillance and Enforcement**: Continuous markets require round‑the‑clock monitoring for fraud, manipulation, and insider trading. The SEC and self‑regulatory organizations (SROs) would need to invest in advanced analytics, AI‑driven surveillance tools, and perhaps even a permanent staffing model to oversee activity at all hours. - **Operational Risks**: Exchanges must ensure that their trading platforms, clearing houses, and settlement systems can handle the increased load without downtime.

This includes robust cybersecurity measures to protect against attacks that could exploit the always‑on nature of the system. - **Market‑Making Incentives**: Traditional market makers provide liquidity during market hours in exchange for certain privileges and compensation. Designing incentives for market makers to operate continuously—especially during periods of low activity—will be essential to maintain healthy order books. - **Investor Protection**: Retail investors may be more vulnerable during off‑peak hours when fewer market participants are present, potentially leading to higher volatility.

The SEC will need to consider safeguards such as volatility controls, circuit breakers, or mandatory disclosure of heightened risks for after‑hours trading. ### Steps the SEC Is Likely to Take In its preparatory meeting, the SEC is expected to outline a phased approach: - **Pilot Programs**: Launch limited‑scope pilots for a select group of tokenized securities, allowing the Commission to gather data on liquidity, price stability, and surveillance effectiveness.

- **Rulemaking Initiatives**: Propose amendments to existing securities‑exchange regulations to explicitly address continuous trading, including definitions, reporting requirements, and compliance timelines. - **Collaboration with Industry**: Work closely with exchanges, fintech firms, and blockchain consortia to develop best‑practice standards for technology, risk management, and investor education. - **International Coordination**: Since nonstop trading blurs geographic boundaries, the SEC may coordinate with foreign regulators to align supervisory frameworks, share surveillance data, and prevent regulatory arbitrage. ### Looking Ahead The SEC’s willingness to explore 24/7 trading marks a pivotal moment in the evolution of U.S.

capital markets. By acknowledging that the digital‑asset landscape operates on a different clock than traditional equities, the agency is positioning itself to foster innovation while still upholding its core mission of investor protection and market integrity. If the Commission successfully integrates continuous trading into its regulatory toolkit, the United States could become a more attractive hub for tokenized securities issuers and traders worldwide. Such a development would likely spur further investment in blockchain infrastructure, encourage the creation of new financial products, and potentially reshape how investors think about market access and timing.

In summary, the SEC’s recent activity—examining around‑the‑clock trading on the same day it green‑lit tokenized securities—signals a strategic alignment of policy with technology. While significant hurdles remain, the potential benefits for liquidity, transparency, and global participation make the case for continued experimentation and thoughtful rulemaking. The coming months will reveal how the Commission balances the promise of nonstop markets with the practical realities of oversight, risk management, and protecting the everyday investor.
