U.S. SEC Initiates Preparations for Continuous Trading, a Practice Common in Crypto Markets

The United States Securities and Exchange Commission (SEC) has taken a notable step toward modernizing its regulatory framework by beginning the groundwork for a trading environment that operates around the clock. This move reflects an awareness that many digital asset markets, particularly those involving cryptocurrencies and tokenized securities, already function on a 24‑hour, seven‑days‑a‑week basis.

While traditional equity markets in the United States have long adhered to fixed trading hours—typically from 9:30 a.m. to 4:00 p.m. Eastern Time—the rapid growth of blockchain‑based assets has highlighted the limitations of such a schedule. Investors, issuers, and market participants in the crypto sphere have grown accustomed to the ability to buy, sell, and transfer assets at any time, regardless of holidays or weekends.

Recognizing this reality, the SEC convened a special session to explore the practicalities, risks, and regulatory safeguards needed to support continuous trading for tokenized securities and other digital assets. ### Why Continuous Trading Matters for Digital Assets The core appeal of cryptocurrencies and tokenized securities lies in their decentralised nature. Unlike traditional securities, which are issued, cleared, and settled through centralized exchanges and custodians, many digital assets are recorded on distributed ledgers that operate globally and without interruption.

This infrastructure enables participants to react instantly to market news, macro‑economic developments, or technological updates. For example, a sudden regulatory announcement in one jurisdiction can trigger immediate price movements across multiple exchanges worldwide. If a market is only open during a narrow window, participants may miss crucial opportunities or be forced to hold positions through periods of heightened uncertainty.

Furthermore, continuous trading can improve price discovery. When markets are open 24/7, the aggregation of supply and demand information occurs in real time, reducing the likelihood of large gaps between closing and opening prices.

This can lead to tighter spreads, lower volatility during traditionally “off‑hours,” and a more accurate reflection of an asset’s true market value. For tokenized securities—traditional financial instruments that have been converted into blockchain‑based tokens—these benefits are especially compelling, as they promise to combine the regulatory protections of conventional securities with the efficiency of digital settlement. ### The SEC’s Dual Agenda: Approval of Tokenized Securities and Market Structure Review On the same morning that the SEC announced its intention to study around‑the‑clock trading, the agency also granted approval for a series of tokenized securities offerings.

These approvals marked a milestone in the agency’s broader strategy to integrate blockchain technology into the existing securities ecosystem. By allowing companies to issue tokenized shares, bonds, or other financial instruments, the SEC signaled that it is willing to apply existing securities laws to new formats, provided that issuers meet the same disclosure, investor protection, and anti‑fraud standards that apply to traditional offerings. The juxtaposition of these two actions—approving tokenized securities while simultaneously examining continuous trading—underscores the SEC’s recognition that the two issues are interlinked. Tokenized securities, by their nature, are likely to be traded on platforms that already support 24/7 operation.

If the regulatory framework continues to impose traditional market‑hour restrictions, issuers and investors could face a mismatch between the technology’s capabilities and the legal environment governing their transactions. Therefore, the SEC’s market‑structure review aims to align the regulatory timetable with the technical realities of blockchain‑based trading. ### Key Considerations in Designing a 24‑Hour Trading Regime 1.

**Liquidity Management**: Continuous trading does not automatically guarantee sufficient liquidity at all times. The SEC must evaluate how market makers, designated liquidity providers, and other participants can be incentivized to supply depth during periods that historically see lower activity, such as late‑night U.S.

hours. Mechanisms may include tiered fee structures, mandatory quoting obligations, or the use of automated market‑making algorithms.

2. **Market Surveillance and Enforcement**: Real‑time monitoring of trading activity is essential to detect manipulation, insider trading, or other illicit behavior.

Extending trading hours expands the window for potential abuse, requiring the SEC and self‑regulatory organizations (SROs) to invest in advanced analytics, AI‑driven pattern recognition, and cross‑border cooperation with foreign regulators. 3.

**Clearing and Settlement**: Traditional securities rely on centralized clearinghouses that operate on business days. To support nonstop trading, the SEC may need to endorse or develop clearing solutions that can settle trades instantly on‑chain or through hybrid models that combine blockchain settlement with existing clearing infrastructure.

This could reduce settlement risk and improve overall market efficiency. 4.

**Investor Protection**: Continuous markets may expose retail investors to heightened risk, especially if they are not accustomed to monitoring positions around the clock. The SEC might consider implementing safeguards such as mandatory risk warnings, limits on leverage, or tools that allow investors to set automatic stop‑loss orders that function 24/7.

5. **Operational Resilience**: Running exchanges and trading platforms without downtime demands robust cybersecurity, disaster‑recovery plans, and redundancy. The SEC will likely require that platforms meet stringent standards for system uptime, data integrity, and protection against cyber‑attacks that could disrupt trading at any hour.

### Potential Benefits for the Broader Financial System If the SEC successfully integrates continuous trading into its regulatory regime, the benefits could extend beyond the crypto sector. Traditional equities, exchange‑traded funds (ETFs), and even fixed‑income products could gradually adopt extended hours, offering investors more flexibility and potentially reducing the impact of after‑hours news shocks. Moreover, a seamless transition to 24/7 trading could attract international capital, as foreign investors would no longer need to coordinate trades around U.S. market closures.

Additionally, the alignment of tokenized securities with continuous trading could accelerate the adoption of blockchain technology across the financial industry. Companies might be more inclined to explore tokenization as a means of raising capital if they know that their securities can be traded at any time, providing greater liquidity for shareholders and a more dynamic secondary market.

### Challenges and the Path Forward Despite the clear advantages, the shift to nonstop trading will not be without obstacles. Market participants must adapt to new operational models, and regulators will need to balance innovation with the mandate to protect investors and maintain market integrity.

The SEC’s approach appears to be incremental: first, granting approvals for tokenized securities under existing rules, and second, launching a comprehensive review of market‑structure implications. Stakeholder input—ranging from exchanges, broker‑dealers, custodians, and technology providers—will be crucial in shaping policies that are both practical and forward‑looking.

In the coming months, the SEC is expected to publish detailed proposals, hold public comment periods, and possibly pilot programs that test continuous trading on a limited basis. These pilots could involve specific tokenized securities or designated digital‑asset exchanges, allowing the agency to gather data on liquidity, volatility, and compliance challenges before rolling out broader reforms.

### Conclusion The SEC’s recent actions signal a pivotal moment in the evolution of U.S. securities markets. By simultaneously approving tokenized securities and initiating a study of around‑the‑clock trading, the agency acknowledges that the future of finance is increasingly digital, global, and always‑on. While substantial work remains to address liquidity, surveillance, settlement, and investor protection concerns, the groundwork being laid today could ultimately result in a more efficient, transparent, and inclusive market ecosystem—one that mirrors the continuous nature of the crypto world while upholding the rigorous standards that protect investors and maintain confidence in the financial system.
