The United States Securities and Exchange Commission (SEC) has recently turned its attention to a concept that has long been taken for granted by participants in digital asset markets: the ability to trade securities around the clock, seven days a week. While traditional equity markets in the United States have historically operated on a fixed schedule—generally from 9:30 a.m.
to 4:00 p.m. Eastern Time on weekdays—cryptocurrency exchanges have been offering 24/7 trading for years, allowing investors to buy, sell, and transfer assets at any hour, any day. Recognizing the growing importance of this capability, the SEC convened a special session to explore the regulatory, technological, and operational implications of extending continuous trading to tokenized securities and other digital financial products.
### Why Around-the-Clock Trading Matters Continuous trading is more than a convenience; it reflects the underlying nature of blockchain technology. Transactions on public blockchains such as Bitcoin, Ethereum, and many others are recorded in a distributed ledger that does not pause for weekends, holidays, or daylight‑saving adjustments. As a result, market participants have become accustomed to immediate price discovery and the ability to react instantly to news events, macro‑economic data releases, or geopolitical developments.
When a major event occurs outside of traditional market hours—say, a sudden regulatory announcement in Europe or a geopolitical shock in Asia—crypto traders can adjust their positions in real time, whereas investors in conventional securities must wait until the next trading day to act. The SEC’s interest in continuous trading stems from several interrelated concerns. First, there is the question of market integrity: how can regulators ensure that price manipulation, insider trading, and other illicit activities are detected and prevented when markets never close?
Second, there are operational challenges related to clearing, settlement, and custody that have historically been designed around a predictable daily cycle. Third, the commission must consider the impact on retail investors, many of whom may be less equipped to manage the heightened risk that comes with nonstop market exposure. ### The Context of Tokenized Securities The same day that the SEC held its round‑table discussion, it also announced the approval of a series of tokenized securities—digital representations of traditional financial instruments that are recorded on a blockchain.
Tokenization promises to increase liquidity, lower transaction costs, and broaden access to investment opportunities that were previously limited to institutional players. However, tokenized securities also blur the line between conventional securities law and the emerging regulatory framework for digital assets. By granting approval for these tokens, the SEC signaled a willingness to embrace innovation while simultaneously acknowledging the need for a robust supervisory regime. Tokenized securities, by design, can be traded on platforms that operate 24/7.
This raises the question of whether the existing regulatory infrastructure—centered on the New York Stock Exchange, Nasdaq, and other legacy venues—can accommodate a market that never shuts down. The SEC’s preparatory work includes examining how existing reporting requirements, such as Form 13F filings and periodic disclosures, might need to be adapted for continuous trading environments.
Moreover, the agency is exploring whether new real‑time surveillance tools, possibly powered by artificial intelligence and machine learning, could be deployed to monitor market activity across all hours. ### Technical and Operational Considerations One of the primary technical hurdles is the integration of continuous trading with the existing clearing and settlement system known as the Depository Trust & Clearing Corporation (DTCC). Currently, the DTCC processes trades in batches at the end of each trading day, a model that would be strained by nonstop activity.
To address this, the SEC is evaluating the feasibility of a real‑time settlement model, where trades are finalized within seconds or minutes of execution, similar to how many cryptocurrency exchanges operate. Another operational factor is market data dissemination. In a 24/7 market, data vendors would need to provide uninterrupted feeds, and exchanges would have to ensure that latency and bandwidth are sufficient to handle constant traffic. The SEC is also reviewing the adequacy of existing market‑making mechanisms, which traditionally rely on designated market makers who provide liquidity during set hours.
Continuous trading may require a new class of liquidity providers who can operate around the clock, possibly leveraging algorithmic strategies and automated market‑making protocols. ### Investor Protection and Education From a consumer‑protection standpoint, the SEC is concerned that retail investors may be exposed to heightened volatility and the temptation to trade impulsively when markets are always open. To mitigate these risks, the commission is considering enhanced disclosure requirements, such as mandatory risk warnings that specifically address the dangers of 24/7 trading, and the development of educational resources that explain how after‑hours price movements can differ from regular‑hours trends.
The agency is also looking at the role of custodians and brokerage firms in safeguarding assets that are held on blockchain platforms. Since tokenized securities can be stored in digital wallets, the SEC wants to ensure that custodial solutions meet stringent security standards and that investors have clear recourse in the event of a breach or loss. ### International Coordination Continuous trading is already the norm in many jurisdictions outside the United States.
European markets, for instance, have been experimenting with extended trading hours for certain asset classes, while Asian exchanges often have overlapping sessions that effectively create near‑continuous coverage across time zones. The SEC’s efforts will therefore involve coordination with foreign regulators to harmonize rules, share surveillance data, and prevent regulatory arbitrage. By aligning its approach with global best practices, the commission hopes to foster a more integrated and resilient market for digital assets.
### Looking Ahead The SEC’s initiative to prepare for around‑the‑clock trading reflects a broader shift in the financial ecosystem toward digitalization and real‑time interaction. While the transition will not be instantaneous, the commission’s proactive stance indicates that it intends to shape the evolution of markets rather than react to it after the fact. Stakeholders—including exchanges, issuers of tokenized securities, custodians, and investors—will need to adapt to new operational models, compliance obligations, and risk‑management frameworks.
In summary, the U.S. Securities and Exchange Commission is actively exploring how to bring the continuous, always‑on nature of crypto trading into the regulated world of securities.
By addressing technical challenges, updating regulatory requirements, and emphasizing investor protection, the SEC aims to create a market environment where the benefits of tokenization and 24/7 liquidity can be realized without compromising the integrity and stability of the broader financial system. The outcome of this work could set a precedent for how traditional markets evolve in the digital age, potentially reshaping trading practices for decades to come.
