The Securities and Exchange Commission will hold a public roundtable on 24-hour trading on September 17, 2026, under File Number 4-913. The discussion is focused on US equity markets, not crypto directly, but the regulator is using crypto's always-on model as a reference point. Crypto markets have operated 24/7 from day one, and traditional finance is now being pushed toward similar infrastructure.
Why the SEC is looking at 24-hour trading
Traditional markets are under pressure to offer round-the-clock access. Crypto normalized always-on trading for millions of investors, especially younger ones. The SEC wants to understand how to extend hours while keeping protections in place. The roundtable will cover overnight trading, clearing requirements, national market system rules, broker-dealer responsibilities, operational resilience, and investor protection.
The hard part: clearing and broker-dealer rules
Clearing and broker-dealer rules are the toughest piece of extending trading hours. Continuous risk systems, order handling, and surveillance would need to run nonstop. That puts new pressure on brokers and clearing firms. A 24-hour market can create benefits, but it also brings thinner liquidity, wider spreads, and more volatile overnight moves. The SEC wants to hear how firms would handle that.
Investor protection concerns
Retail investors may get more access, but they could trade in worse conditions if market depth is weak outside normal hours. Execution quality at off-peak hours is a real worry — wider spreads and thinner liquidity can hurt the small trader. The SEC is weighing how to balance access with protection. Crypto is the reference point because it has already normalized always-on access, but without the same regulatory guardrails.
The roundtable is set for September 17, 2026. The SEC hasn't said whether it will propose rule changes afterward. The biggest unresolved questions are around clearing and broker-dealer responsibilities — how to keep risk systems running 24/7 and who pays for it. The crypto industry will be watching closely.
