What Is an Inter-Depository Transfer? NSDL to CDSL

An inter-depository transfer moves securities from a demat account held with one depository to an account held with the other. India has two depositories, NSDL and CDSL, and a transfer between them travels a different path from an ordinary transfer inside a single depository. SEBI's rules for it are short and old: a two-hour confirmation clock and exactly two permitted grounds for rejection, set by circular dated 23 August 1999 and carried into the Master Circular for Depositories dated 3 December 2024 at para 3.4.2.

Who confirms an inter-depository transfer, and how fast?

The registrar sits in the middle. Because the security's register is maintained at a single point, either in-house by the company or by a SEBI registered registrar and transfer agent, the registrar is the party that has to reconcile a debit in one depository against a credit in the other.

Para 3.4.2 gives it two hours, and makes silence an approval.

The deeming provision is the operative half of the rule. A registrar cannot slow a transfer by not answering, because not answering is treated as a yes.

The two grounds for rejection

Para 3.4.2 states that registrars shall not reject inter-depository transfers except where:

1. A depository does not have an adequate balance of securities in its account, or
2. There is a mismatch of transfer requests from the depositories.

Both are mechanical checks. Neither is discretionary, and no third ground is available. Two supporting rules make the reconciliation possible in the first place: para 3.4.1 requires all share registry work, physical and electronic, to be maintained at a single point, and para 3.4.3 requires every company to appoint the same registrar and share transfer agent for both depositories.

The one-hour settlement case

The two-hour clock is the general rule. There is a tighter one for settlement days that stack.

Para 4.4.1 deals with holidays and force majeure closures, where multiple settlements have to be completed on the working day immediately after the closure. Exchanges must clear and settle those trades sequentially, so the pay-out of the first settlement funds the pay-in of the next. To meet the pay-in obligation for a subsequent settlement, a member may need to move securities from one depository to the other, and para 4.4.1.3 requires the depositories to facilitate those inter-depository transfers within one hour and before pay-in for the subsequent settlement begins.

That is the clearest illustration of why the mechanism matters operationally. On a normal day an inter-depository transfer is housekeeping. On a compressed settlement day it is on the critical path.

Where an inter-depository transfer shows up in the settlement chain

An inter-depository transfer is a transfer instruction like any other, so the same authorisation and validation machinery applies to it.

• The block mechanism applies to intra and inter depository transfer instructions alike: the depositories may keep a block on the securities in the client's account until pay-in day, and release it only against the client-level net delivery obligation from the clearing corporation.
• A delivery instruction slip or an electronic DIS is how a client initiates the debit leg.
• A DDPI is the standing authorisation a broker can hold instead.
• The depository participant is the entity you actually place the instruction with; the depositories themselves have no retail interface.
• A holding statement is where the completed transfer becomes visible to the account holder.

An inter-depository transfer changes which depository holds the record and nothing else about who owns the shares. Para 4.36 makes the same point for the settlement leg: corporate benefits availed by a clearing member, clearing corporation or intermediary are held in trust on behalf of the beneficial owners, and those intermediaries cannot exercise voting rights on securities held in a pool account.
