U.S. SEC Starts Planning for Continuous Trading, a Standard Practice 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 model that has become commonplace in the cryptocurrency ecosystem. This shift in focus came on the very morning that the agency announced its approval of a new class of tokenized securities, signaling a broader willingness to integrate blockchain‑based assets into the traditional financial regulatory framework. Continuous trading, which allows market participants to buy and sell assets at any hour of the day, contrasts sharply with the conventional model used by most U.S.

exchanges, where trading is confined to specific sessions—typically from 9:30 a.m. to 4:00 p.m.

Eastern Time for equities. In the crypto world, however, exchanges operate 24/7, enabling investors to react instantly to global events, news releases, and market sentiment without waiting for the next trading window.

By exploring how to adapt this model for regulated securities, the SEC is acknowledging both the demand for greater market flexibility and the technological advances that make such a system feasible. The SEC’s inquiry into nonstop trading is not merely an academic exercise.

It raises a host of practical considerations that regulators must address to protect investors and maintain orderly markets. Among the most pressing issues are: 1. **Liquidity Management** – Continuous markets can experience periods of thin liquidity, especially during off‑peak hours. The SEC will need to evaluate whether adequate market makers or liquidity providers can be mandated to ensure that price discovery remains reliable and that investors are not subject to extreme price volatility.

2. **Surveillance and Enforcement** – Real‑time monitoring of trading activity is already a cornerstone of market oversight. Extending trading hours means that surveillance systems must operate without interruption, and enforcement teams must be equipped to act on potential violations at any time of day.

3. **Operational Resilience** – Exchanges would have to demonstrate robust technical infrastructure capable of handling the increased load and potential cyber‑security threats that come with a perpetual operating schedule. This includes disaster recovery plans, redundancy measures, and regular stress testing.

4. **Investor Protection** – Retail investors may be more vulnerable during late‑night or early‑morning sessions when market depth is lower and information asymmetry can be higher.

The SEC may consider implementing safeguards such as heightened disclosure requirements, education initiatives, or limits on certain types of orders during low‑liquidity periods. 5.

**International Coordination** – Because cryptocurrency markets are global, a U.S. move toward 24/7 trading would intersect with foreign exchanges that already operate continuously. Harmonizing regulatory standards across jurisdictions could help prevent arbitrage opportunities that exploit regulatory gaps. The timing of the SEC’s exploration is noteworthy.

On the same day that the agency signaled its openness to tokenized securities—a form of digital asset that represents ownership in traditional financial instruments like stocks, bonds, or funds—the conversation about nonstop trading emerged. Tokenized securities combine the legal framework of existing securities with the efficiency and programmability of blockchain technology. By allowing these assets to be issued, transferred, and settled on distributed ledger platforms, issuers can reduce settlement times from days to minutes, lower transaction costs, and broaden access to a global pool of investors. Integrating tokenized securities into a continuous trading environment could amplify these benefits.

For example, investors could trade a tokenized share of a company at any hour, with settlement occurring almost instantly on the blockchain. This would eliminate the need for after‑hours trading windows that currently rely on extended settlement cycles and limited liquidity. Moreover, the transparency inherent in blockchain ledgers could enhance market integrity, as every transaction is recorded immutably and can be audited in real time.

However, the convergence of tokenization and nonstop trading also introduces new regulatory challenges. The SEC must determine how existing securities laws—such as the Securities Act of 1933 and the Securities Exchange Act of 1934—apply when the underlying asset is a digital token rather than a traditional certificate. Questions about custody, voting rights, and dividend distribution need clear guidance to ensure that token holders receive the same protections as conventional shareholders.

In response to these complexities, the SEC has convened a series of round‑table discussions with industry participants, including blockchain platforms, traditional exchanges, market makers, and investor advocacy groups. These dialogues aim to surface practical concerns, test potential rule‑making language, and gauge the readiness of market infrastructure to support a seamless transition to continuous trading for tokenized assets. The broader financial community is watching these developments closely. Proponents argue that around‑the‑clock trading aligns with the digital age, where information flows instantly and investors expect immediate access to markets.

Critics, however, caution that extending trading hours could exacerbate market fragmentation, increase operational risk, and expose less sophisticated investors to heightened volatility. Ultimately, the SEC’s dual focus on tokenized securities and nonstop trading reflects an evolving regulatory philosophy that seeks to balance innovation with investor protection. By carefully crafting rules that address liquidity, surveillance, operational resilience, and cross‑border coordination, the agency hopes to pave the way for a more inclusive, efficient, and modern securities market.

If the SEC proceeds with formal rulemaking, stakeholders can anticipate a phased implementation plan. Initial steps may involve pilot programs on designated platforms, allowing regulators to collect data on trading patterns, liquidity metrics, and system performance. Based on those findings, the SEC could refine its requirements, potentially mandating specific technological standards for order‑matching engines, real‑time reporting protocols, and cybersecurity safeguards. In summary, the SEC’s recent activities signal a significant pivot toward embracing the continuous trading paradigm that crypto markets have normalized for years.

Coupled with its willingness to approve tokenized securities, the agency is laying the groundwork for a future where traditional financial instruments can be bought, sold, and settled at any time, leveraging the speed and transparency of blockchain technology while adhering to the rigorous standards that protect investors and maintain market integrity.
