The US Securities and Exchange Commission plans to convene a roundtable discussion in September to examine the industry's push toward round-the-clock stock trading, as major global exchanges signal a willingness to extend their operating hours.
Regulators Weigh a Nonstop Market
The planned talks come as several of the world's largest exchange operators explore trading models that would keep equity markets open far longer than the traditional business day. The SEC's roundtable is expected to bring together market participants, technology providers and other stakeholders to assess the practical and regulatory challenges of moving toward a 24-hour trading environment.
Extended and continuous trading has long been a feature of cryptocurrency markets, where assets change hands at all hours across the globe. That always-on model has increasingly influenced expectations for traditional finance, with investors and firms questioning why equities remain constrained to fixed sessions.
Wall Street is inching closer to the always-on rhythm that crypto markets have run on for years.
Major Exchanges Line Up
Some of the biggest names in the exchange business are already moving in this direction. Nasdaq, Cboe Global Markets and the London Stock Exchange are among the operators reported to be working toward longer trading windows, reflecting growing demand for greater access to markets.
The shift toward extended hours raises a range of operational questions that regulators and firms will need to resolve. Key considerations include how to maintain adequate liquidity during off-peak periods, how clearing and settlement systems would function around the clock, and how to protect retail investors trading at unusual hours.
Supporters argue that longer trading hours could improve global accessibility, allowing investors in different time zones to react to news and manage positions without waiting for markets to open. Critics caution that thinner overnight liquidity could lead to greater volatility and wider price swings.
