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

The United States Securities and Exchange Commission (SEC) has taken a notable step toward modernizing the structure of U.S. capital markets by initiating a review of proposals that would allow securities to be traded around the clock. This move reflects a growing recognition that the traditional model of trading only during specific hours—typically from 9:30 a.m. to 4:00 p.m.

Eastern Time on weekdays—may be increasingly out of step with the realities of today’s digital economy. In the same morning session when the SEC announced its exploratory work on 24‑hour trading, it also granted approval for a series of tokenized securities, underscoring the agency’s broader interest in integrating blockchain‑based assets into the regulated financial system. ### Why Continuous Trading Matters Historically, U.S.

equity markets have adhered to a fixed schedule that dates back to the era of floor trading. The rationale was straightforward: concentrate liquidity, reduce volatility, and provide a clear window for price discovery. However, the rise of electronic trading platforms, algorithmic strategies, and globalized investment activity has eroded many of the arguments for a limited trading window. Investors now expect immediate access to markets regardless of time zone, and the ability to react to news events in real time.

In the cryptocurrency space, for example, assets such as Bitcoin, Ethereum, and a host of tokenized securities trade nonstop on a global network of exchanges. This around‑the‑clock environment has become the norm rather than the exception, and it has set a new benchmark for what market participants consider standard.

By exploring continuous trading, the SEC is acknowledging that a more flexible schedule could improve market efficiency, enhance price discovery, and reduce the impact of after‑hours price gaps that often occur when markets reopen after a weekend or a holiday. Moreover, a 24‑hour trading framework could attract a broader base of international investors who are currently constrained by the limited U.S. trading window.

### The Tokenized Securities Approval On the same day the SEC announced its intent to study nonstop trading, it also approved a series of tokenized securities. Tokenization involves representing ownership of a traditional asset—such as a share of stock, a bond, or a real‑estate interest—on a blockchain using a digital token. These tokens can be transferred, settled, and recorded on a distributed ledger, offering benefits such as faster settlement times, lower transaction costs, and increased transparency.

The approved tokenized securities were issued by a consortium of fintech firms that have been working closely with the SEC to ensure compliance with existing securities laws. The approval marks a significant milestone because it demonstrates that the regulator is willing to accommodate innovative structures while still enforcing investor protection standards.

It also signals that the SEC sees blockchain technology as a viable tool for modernizing the securities market, rather than a threat to its regulatory framework. ### Potential Benefits of 24‑Hour Trading 1. **Improved Liquidity**: Continuous trading would allow market participants to buy and sell securities whenever demand arises, potentially smoothing out liquidity constraints that can surface during the traditional closing period. 2.

**Reduced Volatility Gaps**: Overnight news events often lead to sharp price movements when markets reopen. A nonstop market could incorporate new information as it becomes available, mitigating abrupt price jumps. 3. **Global Participation**: Investors in Asia, Europe, and other regions would no longer need to wait for the U.S.

market to open, fostering a more inclusive and globally integrated market. 4. **Enhanced Price Discovery**: With more data points throughout the day, price formation could become more accurate, reflecting a wider array of market sentiments and information. 5.

**Alignment with Crypto Practices**: As crypto assets continue to trade 24/7, aligning traditional securities with this model could reduce arbitrage opportunities and bring consistency across asset classes. ### Challenges and Considerations While the advantages are compelling, the SEC must also address several practical and regulatory challenges before implementing round‑the‑clock trading: - **Market Surveillance**: Continuous monitoring for fraud, manipulation, and insider trading would require advanced technology and staffing models that can operate 24/7. - **Infrastructure Readiness**: Exchanges, clearinghouses, and custodians would need to upgrade their systems to handle nonstop activity, including settlement cycles and risk management protocols.

- **Investor Protection**: Retail investors may be more vulnerable to impulsive decisions when markets are always open. The SEC would need to consider safeguards such as extended cooling‑off periods or enhanced disclosure requirements.

- **International Coordination**: Aligning U.S. trading hours with those of foreign markets could raise cross‑border regulatory issues, necessitating cooperation with foreign securities regulators. ### The Path Forward The SEC’s decision to launch a study on continuous trading is an exploratory step rather than an immediate policy change. The agency is likely to solicit feedback from market participants, including exchanges, broker‑dealers, institutional investors, and consumer advocacy groups.

It may also commission research on the operational impacts, cost implications, and potential market outcomes of a nonstop trading environment. In parallel, the tokenized securities approval provides a concrete example of how the SEC can blend innovation with regulation. By establishing clear guidelines for token issuance, custody, and reporting, the commission is laying the groundwork for a future where digital assets coexist seamlessly with traditional securities. ### Conclusion The U.S.

Securities and Exchange Commission is at a crossroads where the legacy of a fixed‑hour market meets the demands of a digital, globally connected economy. By examining the feasibility of 24‑hour trading and simultaneously endorsing tokenized securities, the SEC is signaling a willingness to adapt its regulatory approach to the evolving landscape. If the agency can successfully navigate the technical, supervisory, and investor‑protection challenges, continuous trading could become a new standard, offering greater liquidity, improved price discovery, and a more inclusive market for participants around the world.

The coming months and years will reveal whether these initiatives evolve from exploratory studies into concrete policy reforms that reshape how securities are bought, sold, and settled in the United States.
