Crypto markets operate without a closing bell, but the systems that support traditional securities still depend on fixed sessions, overnight breaks and business-day settlement. As exchanges, clearinghouses and financial technology firms explore tokenized assets and continuous trading, they are confronting a difficult question: can markets run around the clock without weakening oversight, liquidity and investor protection?
The contest to build a permanent trading market is moving from the crypto sector into the infrastructure of conventional finance.
Digital asset exchanges already operate continuously. Prices change on weekends, collateral values move while banks are closed, and leveraged positions can be liquidated at any hour. By contrast, most US stocks, exchange-traded funds and other securities remain tied to defined trading sessions. Their clearing, settlement, custody and corporate action processes also depend on schedules built around the working week.
That difference has become increasingly important as financial institutions experiment with tokenized securities, digital collateral and blockchain-based settlement. A tokenized Treasury fund or digitally represented share may trade on a platform that is technically available at all times. Yet the underlying legal ownership, settlement process, cash movement, compliance checks and issuer obligations may still operate on a conventional timetable.
The result is a market that can appear continuous on the screen while remaining intermittent underneath.
Crypto exchanges and traditional market operators are now racing to close that gap. Their proposals vary. Some involve extended hours for existing securities. Others envision securities issued directly on distributed ledger networks, with smart contracts automating parts of the trading and settlement process. Still others focus on connecting existing exchange, clearing and custody systems so that transactions can be processed outside standard business hours.
The Depository Trust and Clearing Corporation, or DTCC, has highlighted the potential of distributed ledger technology and digital settlement in its industry initiatives and public commentary. The organization sits at the center of the US post-trade system, providing clearing, settlement and information services for much of the securities market. Its involvement is significant because a truly continuous market cannot be created by trading venues alone. The infrastructure that confirms ownership, transfers cash, manages collateral and records corporate actions must also be available.
The Securities and Exchange Commission has meanwhile continued to emphasize the importance of investor protection, market integrity and compliance when new technologies are applied to securities markets. The agency’s approach is central to the debate because putting a stock or fund on a blockchain does not remove it from securities law. The technology may change how an asset is represented or transferred, but it does not automatically change the obligations of brokers, exchanges, issuers, custodians or investors.
The Chicago Mercantile Exchange has offered another important model. Its markets operate for much of the week, with scheduled breaks rather than a complete 24 hour, seven day schedule. That structure demonstrates how established derivatives venues have extended access while preserving maintenance windows, risk controls and operational procedures. It also shows why a permanent market is not simply a matter of leaving a matching engine switched on.
The problem created by different clocks
The strongest argument for continuous securities trading comes from the relationship between crypto and traditional finance.
Digital assets are priced every day, including Saturdays, Sundays and public holidays. Stablecoins can transfer value at any hour. Decentralized finance protocols can issue margin calls and liquidate collateral according to software rules. Even when market activity is thin, prices continue to move.
A fund, broker or institutional investor that uses digital assets as collateral therefore faces exposure outside the hours when conventional securities markets are open. A sharp weekend decline in bitcoin or another major token can reduce the value of collateral before a traditional portfolio manager can sell shares or raise cash through ordinary market channels. When securities markets reopen, the adjustment may appear as a large gap rather than a gradual repricing.
Continuous trading would not eliminate volatility. It could, however, distribute some price discovery across more hours. Investors would have more opportunities to respond to information, and institutions could potentially rebalance collateral before the next formal session.
The same logic applies to news. Geopolitical events, cyberattacks, central bank announcements and corporate developments rarely follow exchange calendars. If a company announces material information on a Saturday, investors may be forced to wait until Monday to trade the affected security. A continuous venue could allow the market to process that information sooner.
There are also potential benefits for global investors. A US security available only during American trading hours can be inconvenient for investors in Asia, the Middle East or Europe. Extended access could make markets more inclusive and help align trading with the hours when international capital is active.
For issuers, digital markets may offer faster settlement and broader distribution. Tokenized funds could allow investors to subscribe or redeem outside banking hours. Digital collateral could move between venues without waiting for a conventional batch process. Smaller investors might gain access to products that are currently restricted by minimum sizes, geographic limitations or slow administrative procedures.
Yet these benefits depend on more than technical availability. Liquidity is the critical constraint.
A market can be open at 3 a.m. and still be difficult to use if there are few buyers and sellers. Wide spreads, sudden price movements and limited depth can make continuous access more expensive, particularly for retail investors. A nominally open market may therefore create the appearance of choice without delivering reliable execution.
Liquidity does not arrive automatically
Traditional exchanges have long used opening and closing auctions to concentrate orders and establish reference prices. Those periods can help reduce uncertainty by bringing a large number of participants together at predictable times.
A fully continuous market could weaken that concentration. If trading is spread across every hour, liquidity may fragment between venues and time zones. One platform could show a price that differs materially from another because the available orders are not the same. Arbitrage firms may help narrow those gaps, but they cannot guarantee orderly markets during a crisis.
Tokenized securities create an additional fragmentation risk. The same economic interest could be represented on several blockchains, in different custody systems or through separate platforms. Unless those records are interoperable, investors may not be trading one unified market. They may be trading several connected but imperfectly synchronized markets.
This is a familiar challenge in crypto. Digital assets can be listed on numerous exchanges, each with its own order book, rules and operational risks. A similar structure applied to regulated securities could complicate best execution, surveillance and investor disclosures.
The question of who provides liquidity is also unresolved. Market makers need predictable access to capital, settlement and hedging instruments. If banks and broker dealers remain staffed according to a weekday schedule, they may be reluctant to commit balance sheet capacity during overnight or weekend periods. Crypto native firms may be willing to operate continuously, but their regulatory status, capital resources and risk management standards vary widely.
A 24/7 market could consequently be most liquid during the same hours that conventional markets already favor. Outside those periods, investors could face higher costs and more frequent price dislocations.
Settlement is harder than trading
The most visible part of a market is the trading screen. The least visible part is the post-trade system, where most of the legal and operational work occurs.
After a transaction, the market must determine who owns the asset, who owes cash, how the trade is netted, whether the securities are available, and how failures are managed. Custodians must update records. Brokers must calculate customer balances. Clearinghouses must collect collateral and manage default risk. Issuers must distribute dividends, process splits and communicate material events.
A blockchain can record transfers quickly, but speed does not resolve every legal question. A transaction might be final in software while remaining subject to reversal under insolvency law, fraud rules or court order. The parties must know whether a ledger entry represents legal ownership, a beneficial interest or merely a contractual claim on an intermediary.
Settlement also requires cash. Stablecoins may provide a method for moving digital value, but their use in securities markets raises questions about reserves, redemption, supervision and the treatment of a failed issuer. Commercial bank money remains deeply integrated into the existing financial system. Connecting it to a continuous securities market could require new payment arrangements, central bank infrastructure or carefully regulated private settlement assets.
The DTCC’s role illustrates why industry experimentation is likely to proceed through regulated intermediaries rather than through a simple replacement of the current system. Market participants may adopt distributed ledgers for specific functions, such as recording ownership, moving collateral or improving reconciliation, while retaining established controls around clearing and custody.
That hybrid approach could reduce operational risk, but it may also limit the speed and openness associated with crypto networks. The market will need to decide which functions should be automated, which require human review and which must remain reversible in exceptional circumstances.
Surveillance cannot take a weekend off
Continuous trading expands the period during which misconduct can occur.
Market manipulation, insider trading, spoofing, wash trading and abusive short selling do not depend on office hours. A venue that operates every day must monitor orders and transactions continuously, preserve records and respond quickly to suspicious activity. The challenge becomes more difficult when trading occurs across multiple platforms and jurisdictions.
Crypto markets have demonstrated the value of real-time blockchain data, but public transaction records do not provide a complete surveillance system. A blockchain may show that assets moved between addresses without revealing who controlled those addresses, why the transfer occurred or whether related accounts were acting together. Securities surveillance requires additional information about beneficial ownership, customer relationships, trading intentions and communications.
Regulators also need access to reliable data. If a security trades on a permissioned blockchain, the operator may control the records. If it trades across several venues, authorities need mechanisms to obtain a consolidated view. If markets operate across borders, agencies must coordinate rules for reporting, enforcement and data sharing.
The SEC’s public work on market structure and digital assets points to a broader principle: technological innovation does not reduce the need for transparent rules. It may instead make the rules more difficult to apply. A venue that handles tokenized securities could fall within several regulatory categories depending on its functions. It might be treated as an exchange, broker, clearing agency, transfer agent or custody platform, with separate obligations attached to each role.
That classification matters for investors. A customer who believes that a token is equivalent to a traditional share may not understand the difference between holding the security directly and holding a digital claim through an intermediary. Disclosures must explain voting rights, bankruptcy treatment, redemption procedures, settlement risks and the consequences of a network outage.
Corporate actions expose the weakest links
Trading is only one part of owning a security. Corporate actions create some of the most complicated demands on market infrastructure.
A stock may pay a dividend, split its shares, conduct a tender offer or distribute rights to existing holders. A fund may calculate its net asset value, accept subscriptions and process redemptions. These events require accurate records at specific times. They also require communication with investors and coordination among issuers, custodians, brokers and transfer agents.
A 24/7 environment could make some processes faster. Smart contracts might automatically distribute a dividend or update balances after a stock split. But automation can also magnify mistakes. An incorrect data feed or flawed contract could distribute assets to the wrong accounts at scale.
There must also be a mechanism for handling disputes and unexpected events. What happens if an issuer announces a correction after an automated distribution? What happens if a blockchain experiences a software failure during a tender offer? Can a transfer be paused without undermining confidence in settlement finality?
Traditional markets rely on procedures, committees and designated officials to manage such situations. A continuous digital market would need equivalent authority, even if many processes are automated. Someone must be able to halt trading, correct records, investigate errors and communicate with investors.
The global regulatory race
The competition is not limited to the United States. European regulators are developing frameworks for digital assets and market infrastructure under the Markets in Crypto Assets regime and related experiments with distributed ledger technology. The United Kingdom has explored digital securities sandboxes and broader financial market innovation. Asian financial centers, including Singapore and Hong Kong, have promoted tokenization projects while maintaining close regulatory oversight.
These jurisdictions are likely to make different choices about trading hours, settlement assets, custody and market access. If the United States moves slowly, financial firms could direct new activity to markets with clearer rules or more flexible operating models. If regulators move too quickly, they could create fragmented systems that are difficult to supervise and vulnerable to operational failures.
The challenge is especially acute for globally traded assets. A tokenized US Treasury product may attract investors around the world, but the issuer must comply with rules governing securities, payments, sanctions, tax reporting and data protection in multiple countries. A trading venue that never closes must also manage holidays, emergency interventions and differences in legal time.
International coordination will therefore be important. Common technical standards could allow assets and cash to move between systems without forcing investors to open multiple accounts. Shared approaches to identity, settlement finality and insolvency could reduce uncertainty. Without that coordination, the industry may build a collection of private networks that are individually efficient but collectively fragmented.
The likely path is controlled continuity
The financial system is unlikely to move directly from weekday sessions to an unrestricted 24/7 securities market. A more probable path is gradual.
The first stage may involve extended hours for selected products, particularly government securities, money market funds and tokenized funds. These instruments generally have more standardized pricing and may be easier to support than individual stocks. Venues could then add weekend access for limited classes of investors or for transfers between approved institutions.
The next stage could connect digital collateral systems to conventional clearinghouses. This would address one of the most immediate problems created by different market clocks. If collateral can move or be valued outside traditional hours, institutions may manage risk more effectively without opening every security to continuous public trading.
Over time, market operators may introduce scheduled pauses rather than a universal closing bell. These pauses could support maintenance, reconciliation, upgrades and emergency reviews. The CME’s approach to extended trading offers a practical reference point, since it combines broad availability with planned interruptions and established risk controls.
Regulators will also need to distinguish access from suitability. A market being open does not mean every investor should trade at every hour. Brokers may need to provide warnings about thin liquidity, higher spreads and limited customer support. Rules on margin, leverage and forced liquidation will require particular attention. A retail investor who receives a margin call at 2 a.m. should not be exposed to an automated sale without clear protections and a reasonable opportunity to respond.
The ultimate test will be whether continuous markets improve resilience rather than merely extending activity. Faster settlement is valuable if it reduces counterparty risk. Round-the-clock access is useful if it allows investors to respond to information without creating disorderly trading. Tokenization has promise if it lowers administrative costs while preserving legal clarity.
But technology alone cannot deliver those outcomes. The market needs capital, supervision, accountable intermediaries and rules for failure. It needs reliable links between trading, clearing, custody and payments. It needs international cooperation and clear disclosures for investors.
Crypto platforms have shown that financial markets can operate without a closing bell. Traditional institutions are now asking whether that model can be adapted to regulated securities without importing the sector’s operational weaknesses. The answer will determine more than trading hours. It will shape who controls market infrastructure, how collateral moves through the financial system and whether the boundary between crypto exchanges and capital markets remains meaningful.
A continuous market may eventually become normal. It will become trustworthy only when its protections are as available as its trading screen, every hour of every day.
