U.S. Securities Regulator Starts Planning for 24‑Hour Trading, a Practice Already Common in Crypto Markets

The United States Securities and Exchange Commission (SEC) has taken its first formal steps toward evaluating a trading framework that would allow securities to be bought and sold around the clock, mirroring the continuous market model that has become standard in the cryptocurrency space. This development was announced during a morning briefing that coincided with the agency’s decision to approve a series of tokenized securities—digital assets that represent ownership in traditional financial instruments but are issued and transferred on blockchain networks.

Historically, U.S. equity markets have operated on a set schedule, typically opening at 9:30 a.m. Eastern Time and closing at 4:00 p.m.

on weekdays, with limited after‑hours sessions that capture only a fraction of the total trading volume. The idea of extending market hours to a full 24‑hour cycle has been discussed for years, especially as investors and issuers have grown more accustomed to the always‑on nature of digital asset trading.

Cryptocurrencies such as Bitcoin, Ether, and a host of other tokens trade on global exchanges that never close, providing instant price discovery and liquidity at any hour of the day. The SEC’s recent move signals that regulators are beginning to confront the practical and legal challenges that a nonstop securities market would raise. Among the key issues under review are: 1. **Investor Protection** – Continuous trading could expose retail investors to heightened volatility and reduced oversight during periods when market makers and institutional participants are less active.

The agency must consider how to maintain fair‑price mechanisms, prevent market manipulation, and ensure that disclosure obligations are met at all times. 2.

**Operational Infrastructure** – Existing clearinghouses, settlement systems, and custodial services are built around the traditional trading day. Transitioning to a 24‑hour model would require upgrades to technology platforms, real‑time risk‑management tools, and possibly new regulatory frameworks for cross‑border coordination.

3. **Regulatory Coordination** – Because crypto exchanges already operate nonstop and often span multiple jurisdictions, the SEC will need to work closely with other U.S. agencies such as the Commodity Futures Trading Commission (CFTC) and the Financial Industry Regulatory Authority (FINRA), as well as foreign regulators, to create a cohesive set of rules that prevent regulatory arbitrage. 4.

**Market Integrity** – Continuous markets could affect price formation and liquidity patterns. Studies from other asset classes, such as foreign exchange, suggest that liquidity can thin out during certain hours, leading to larger spreads and potential price distortions.

The SEC will likely examine whether similar dynamics could emerge for tokenized securities and how to mitigate them. The agency’s decision to approve tokenized securities on the same day underscores a broader shift toward embracing blockchain technology within the traditional financial system. Tokenized securities are essentially digital representations of stocks, bonds, or other financial instruments that are recorded on a distributed ledger. By issuing these assets on a blockchain, issuers can potentially lower transaction costs, speed up settlement from days to minutes, and broaden access to investors worldwide.

In the briefing, SEC officials highlighted that the approval of tokenized securities does not automatically grant them the right to trade nonstop. Instead, each product must still comply with existing securities laws, including registration requirements, reporting standards, and anti‑fraud provisions. The agency emphasized that any move toward 24‑hour trading would have to be incremental, starting perhaps with pilot programs or limited‑scope experiments that allow regulators to gather data and assess risks before a full rollout.

Industry participants have responded with a mixture of optimism and caution. Crypto exchanges that already support tokenized assets see the SEC’s interest in continuous trading as a validation of the model that has driven their growth.

They argue that investors benefit from the ability to react to news and market events in real time, rather than being forced to wait for the next trading session. Conversely, traditional brokerage firms and market infrastructure providers warn that the shift could strain existing systems and require substantial investment in new technology and compliance processes. Analysts also note that a 24‑hour securities market could attract new capital flows, particularly from regions where investors are accustomed to nonstop trading.

This could enhance market depth and price efficiency, but it could also introduce new forms of systemic risk if not properly managed. For example, a sudden surge in trading activity during off‑peak hours could overwhelm liquidity providers, leading to flash crashes or other destabilizing events. Looking ahead, the SEC has indicated that it will convene a series of workshops and public comment periods to gather input from market participants, technology providers, and consumer advocates. These sessions are expected to explore practical considerations such as: - The design of real‑time surveillance tools that can detect manipulative behavior across all hours.

- The role of custodians in safeguarding digital assets when markets never close. - How to align tax reporting and record‑keeping obligations with continuous trading activity. - Potential pilot programs that could test 24‑hour trading for a limited set of tokenized securities before broader implementation.

In summary, the SEC’s recent actions mark a pivotal moment in the convergence of traditional finance and the digital asset ecosystem. By beginning to explore the feasibility of a nonstop trading environment while simultaneously approving the issuance of blockchain‑based securities, the agency is laying the groundwork for a more integrated, flexible, and technologically advanced market structure.

The path forward will require careful balancing of innovation with investor protection, robust infrastructure upgrades, and coordinated regulatory oversight. If successfully implemented, a 24‑hour trading model could reshape how securities are bought and sold, offering greater accessibility and efficiency for a global investor base while preserving the core principles of market fairness and transparency.
