Demat Debit and Pledge Instruction extension delays implementation; exchanges must notify members and update websites under regulatory powers. SEBI extends the implementation timeline for the Demat Debit and Pledge Instruction (DDPI) regime for transfers of securities for deliveries/settlement obligations and pledging/re pledging, postponing the prior commencement date to allow depositories additional time to complete system changes. Stock Exchanges and Depositories must notify members/participants and publish the extension on their websites; the directive is issued under SEBI's statutory powers to protect investors and regulate the securities markets.
