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

The United States Securities and Exchange Commission (SEC) has recently signaled a shift in its regulatory outlook by embarking on a comprehensive review of continuous, or "around‑the‑clock," trading practices—an approach that has become commonplace in the cryptocurrency sector. This move coincides with the agency’s approval of the first tokenized securities offerings, underscoring a broader willingness to engage with innovative financial products that leverage blockchain technology. **Why the SEC is Looking at 24/7 Trading** Traditional equity markets in the United States operate on a fixed schedule, typically opening at 9:30 a.m.

Eastern Time and closing at 4:00 p.m. Eastern Time, Monday through Friday, with holidays and occasional early closures. This framework, inherited from the era of floor trading, has long been justified on the grounds of providing orderly price discovery, limiting volatility, and allowing market participants to process information in a predictable environment.

However, the rapid rise of digital assets—cryptocurrencies, security tokens, and other blockchain‑based instruments—has introduced a new paradigm where trading never truly stops. Crypto exchanges such as Binance, Coinbase, and Kraken facilitate transactions 24 hours a day, seven days a week, across global time zones.

Investors and issuers have begun to demand the same level of accessibility for tokenized securities, which are essentially traditional financial instruments (like stocks, bonds, or real‑estate interests) represented on a blockchain. The appeal is clear: greater liquidity, lower settlement times, and the potential for fractional ownership.

Yet, the SEC’s existing rules were crafted for a market that pauses each night and on weekends. By examining the mechanics of nonstop trading, the agency hopes to determine whether existing investor‑protection safeguards—such as market‑wide circuit breakers, disclosure requirements, and surveillance mechanisms—can be adapted to a round‑the‑clock environment. **The Context of Tokenized Securities Approval** On the same morning that the SEC’s staff released a briefing on continuous trading, the agency announced the approval of a pilot program for tokenized securities. The program allows a limited group of qualified investors to purchase digital representations of shares in a private company, with the tokens recorded on a public blockchain.

This approval marks a historic first: the SEC formally recognizing a blockchain‑based security as meeting its definition of a “security” while also meeting the regulatory standards for registration, reporting, and investor eligibility. The timing of these two developments is unlikely to be coincidental. By green‑lighting tokenized securities, the SEC is effectively testing the waters of how blockchain‑based assets can be integrated into the existing regulatory regime. Continuous trading is the logical next step, because one of the most compelling benefits of tokenization is the ability to trade assets instantly, without waiting for the next market opening.

If the SEC can devise a framework that preserves market integrity while allowing 24/7 access, it could set a precedent that reshapes the entire U.S. securities landscape. **Key Challenges the SEC Must Address** 1.

**Market Surveillance and Manipulation Detection**: Traditional exchanges rely on centralized monitoring systems that operate during market hours. Extending surveillance to a 24‑hour model means developing or adapting technology capable of real‑time analysis of trade data across multiple venues, including decentralized exchanges (DEXs) that may not provide the same level of data transparency. 2.

**Liquidity and Volatility Management**: Continuous markets can experience periods of thin liquidity, especially outside of normal business hours, which can lead to price spikes or gaps. The SEC will need to consider whether to implement circuit‑breaker mechanisms that trigger automatically when price movements exceed predefined thresholds, regardless of the time of day. 3.

**Investor Protection and Disclosure**: Investors must have access to timely and accurate information to make informed decisions. In a nonstop market, the timeliness of disclosures—such as earnings releases, material events, or regulatory filings—becomes even more critical.

The SEC may need to mandate real‑time disclosure updates or require issuers to use blockchain‑based notice systems that broadcast information instantly to all token holders. 4. **Cross‑Border Coordination**: Because crypto markets operate globally, a U.S.‑only approach could create regulatory arbitrage opportunities. The SEC will likely need to coordinate with foreign regulators, such as the European Securities and Markets Authority (ESMA) and the Financial Conduct Authority (FCA) in the United Kingdom, to develop harmonized standards for continuous trading of tokenized securities.

5. **Technology Standards and Interoperability**: Not all blockchains are created equal. The SEC must decide whether to endorse specific blockchain protocols (e.g., Ethereum, Solana, Polygon) or to adopt a technology‑agnostic stance. Establishing standards for smart‑contract security, auditability, and interoperability will be essential to ensure that tokenized securities can be traded seamlessly across different platforms.

**Potential Benefits of a 24/7 Market** If the SEC successfully crafts a regulatory framework that accommodates nonstop trading, several advantages could accrue to both issuers and investors: - **Increased Liquidity**: Continuous trading can attract a broader pool of participants, including international investors who may otherwise be constrained by U.S. market hours. - **Faster Price Discovery**: Real‑time trading allows market prices to reflect new information almost instantly, reducing the lag that can occur in a market that closes for several hours each day. - **Reduced Settlement Times**: Blockchain‑based settlement can occur within minutes, compared to the traditional T+2 (trade date plus two business days) model, lowering counterparty risk.

- **Greater Access for Retail Investors**: With tokenization, even small investors can purchase fractional shares, and a 24‑hour market removes the barrier of having to trade during a specific window. **What Comes Next?** The SEC’s internal working group on continuous trading is expected to produce a detailed report later this year, outlining proposed rule changes, technology requirements, and enforcement strategies.

Public comment periods will likely follow, giving industry participants, consumer advocates, and academic researchers an opportunity to weigh in on the proposed framework. Meanwhile, market participants are already positioning themselves for a potential shift. Several fintech firms are developing compliance‑focused trading platforms that integrate real‑time monitoring tools, while traditional broker‑dealers are exploring partnerships with blockchain infrastructure providers to offer tokenized products to their clients. In summary, the SEC’s dual actions—examining around‑the‑clock trading and approving tokenized securities—represent a watershed moment for U.S.

capital markets. By confronting the technical, regulatory, and operational challenges head‑on, the agency is laying the groundwork for a more inclusive, efficient, and modern securities ecosystem.

Should these efforts succeed, the United States could become a global leader in the seamless integration of blockchain technology with regulated financial markets, offering investors the flexibility of crypto‑style trading while preserving the safeguards that have long underpinned market confidence.
