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

The United States Securities and Exchange Commission (SEC) has recently turned its attention to the concept of continuous, or around‑the‑clock, trading—a practice that has long been taken for granted in the cryptocurrency ecosystem. While traditional equity markets in the United States operate within set hours—typically from 9:30 a.m. to 4:00 p.m.

Eastern Time, Monday through Friday—the digital‑asset world never sleeps. Crypto exchanges allow buying, selling, and price discovery at any hour of the day, any day of the week, and the SEC’s recent deliberations suggest that regulators are beginning to recognize the need to adapt their frameworks to this reality. ### Why the SEC Is Considering 24/7 Trading The push toward nonstop trading stems from several interrelated factors.

First, the rapid growth of tokenized securities—digital representations of traditional financial assets such as stocks, bonds, or real‑estate interests—has created a hybrid market where the line between conventional securities and crypto‑based instruments is increasingly blurred. When the SEC approved a handful of tokenized securities earlier this week, it signaled a willingness to integrate blockchain‑based products into the regulated securities arena.

However, the approval also highlighted a mismatch: the underlying assets are now subject to the same market‑driven price fluctuations that occur in crypto markets, yet the regulatory infrastructure still adheres to a rigid, nine‑to‑five schedule. Second, market participants—including institutional investors, fintech firms, and retail traders—have voiced frustration over the limited trading windows. In a globalized economy, investors often need to respond to news events, earnings releases, or macro‑economic data that occur outside of U.S.

market hours. The inability to act immediately can lead to price gaps, heightened volatility, and potential arbitrage opportunities that undermine market fairness. By moving toward a model that allows continuous trading, the SEC hopes to reduce these inefficiencies and provide a more level playing field.

Third, the technology that underpins blockchain—smart contracts, decentralized ledgers, and automated market makers—makes it technically feasible to operate a secure, transparent exchange that runs 24/7. Unlike legacy trading platforms that rely on centralized order books and manual settlement processes, many crypto exchanges have built-in mechanisms for instant settlement and real‑time order matching.

The SEC’s exploration of continuous trading therefore reflects an acknowledgement that the existing infrastructure can support such a shift, provided that appropriate safeguards are put in place. ### Potential Benefits and Challenges **Benefits** 1. **Improved Liquidity**: Continuous trading can attract a broader pool of participants from different time zones, increasing the depth of the market and reducing bid‑ask spreads. 2.

**Reduced Price Gaps**: By allowing trades to occur whenever news breaks, markets can adjust more smoothly, limiting abrupt price jumps that occur when the market reopens after a closure. 3.

**Enhanced Investor Access**: Retail investors who cannot trade during traditional market hours—due to work or personal commitments—would gain greater flexibility. 4. **Alignment with Global Standards**: Many foreign exchanges already operate for extended hours or have multiple trading sessions.

Adopting a similar model would bring U.S. markets into closer alignment with international practices. **Challenges** 1.

**Regulatory Oversight**: Continuous operation demands round‑the‑clock monitoring by regulators, surveillance teams, and compliance officers. This raises staffing and technology costs. 2. **Systemic Risk Management**: Market‑wide stress events could unfold without the natural “cool‑down” period that a daily market close provides.

The SEC would need robust risk‑mitigation tools, such as circuit‑breaker mechanisms that function at any hour. 3. **Operational Resilience**: Exchanges must guarantee uptime, cybersecurity, and data integrity 24/7, which may require significant investment in infrastructure and redundancy. 4.

**Investor Protection**: Retail participants may be more vulnerable to impulsive decisions during off‑hours when market volatility can be higher. Educational resources and protective measures would be essential.

### The SEC’s Approach and Timeline During a public hearing held on the same morning the commission approved the first batch of tokenized securities, SEC Chair Gary Gensler emphasized the need for a “thoughtful, data‑driven approach” to any potential shift toward continuous trading. The agency has tasked its Market Structure and Innovation divisions with conducting a comprehensive study that will examine historical data on after‑hours trading, evaluate the operational capabilities of existing exchanges, and assess the impact on market integrity. The study is expected to produce a preliminary report within the next twelve months, followed by a period of public comment.

Stakeholders—including traditional stock exchanges, crypto platforms, broker‑dealers, and consumer advocacy groups—will have the opportunity to submit feedback on proposed rule changes. The SEC has indicated that any final rulemaking could take several additional years, reflecting the complexity of balancing innovation with investor protection.

### What This Means for Market Participants For issuers of tokenized securities, the prospect of 24/7 trading could make their offerings more attractive to a global investor base, potentially lowering the cost of capital and increasing market efficiency. For traditional exchanges, it may prompt a strategic reassessment of their operating models, perhaps leading to partnerships with fintech firms that specialize in continuous‑trading technology. Investors, both retail and institutional, should begin preparing for a possible transition by reviewing their compliance policies, risk‑management frameworks, and technology stacks.

Firms that can adapt quickly to a nonstop market environment may gain a competitive edge, while those that lag could find themselves at a disadvantage. ### Conclusion The SEC’s move to explore around‑the‑clock trading represents a significant step toward bridging the gap between legacy securities markets and the fast‑moving world of digital assets. While the regulatory path forward is still being charted, the discussion underscores a broader trend: financial markets are evolving to become more inclusive, flexible, and technologically advanced.

Whether the United States will fully embrace 24/7 trading remains to be seen, but the conversation has already begun, and its outcomes will shape the future of securities trading for years to come.
