U.S. SEC Chair: Advancing 24-Hour U.S. Stock Trading; Tokenization May Facilitate Real-Time Inventory Management

TechFlow reports that on September 17, US SEC Chairman Paul S. Atkins released remarks from a roundtable meeting, in which he commented on the SEC's ongoing preparations to expand US stock market trading to 24 hours. Extending trading hours is expected to enable investors to respond more timely to market events, broaden global market participation, and enhance liquidity. Atkins noted that DTCC has already gone live with its "23×5" trade capture system to support clearing and settlement. The industry has also established overnight price limits and risk management requirements for relevant trading venues. Security Information Processors (SIPs) are preparing to disseminate overnight prices, while tokenization is expected to help the securities industry achieve real-time inventory management, improve efficiency, reduce settlement failures, and lower the risk of naked short selling.
