T+3 IPO Listing Settlement Timeline: Demat Credit, Mandate Revocation & Refund Workflow

1. Overview of the SEBI T+3 Listing Regime

In December 2023, the Securities and Exchange Board of India (SEBI) transitioned all Mainboard and SME public issues to a mandatory T+3 settlement cycle, replacing the older T+6 framework.

This compressed timeline benefits retail investors by reducing the duration their capital remains blocked and giving companies faster access to expansion capital.

4. Troubleshooting Delayed UPI Mandate Releases

If your bank balance remains lien-blocked past T+2:

Contact your bank's UPI grievance cell with your Application Number and Unique Mandate Reference Number (UMRN).

Under SEBI guidelines, banks failing to unblock funds on time are liable to pay compensation at 15% per annum for each day of delay.
