DTCC’s NSCC Expands Trade Clearing to 24 Hours on Business Days

DTCC’s National Securities Clearing Corporation (NSCC) has moved to clearing trades 24 hours a day on every business day, following DTCC’s processing of roughly $3.7 quadrillion last year. According to NS3.AI, the U.S. Securities and Exchange Commission (SEC) approved the related rule change before client testing began earlier this year. The update comes as major exchanges, including Nasdaq, are expected to introduce overnight trading sessions later this year and continuing into 2027.
