Question

When does NSCCL identify short deliveries?

Hint:

If a seller does not deliver shares by the pay-in deadline, NSCCL automatically flags a short delivery and buys the shares in an auction at the defaulting seller's expense.

Answer 1

Step 1: Defining Short Delivery:
A short delivery occurs when a selling broker or clearing member fails to deliver the required quantity of shares to the clearing corporation during the designated settlement window.

Step 2: Pinpointing the Identification Phase:
NSCCL (NSE Clearing Limited) identifies short deliveries at the close of the Securities Pay-in phase of the settlement cycle. Under modern trading rules, this occurs on T+1 settlement day (Trade date plus one business day).

Step 3: Detail on the Resolution Process:

• Once pay-in obligations are computed, the clearing engine matches seller deliveries against buyer receipts.
• Any deficit is flagged as a short delivery.
• To resolve the short delivery, NSCCL initiates a buy-in auction on $T+1$ or $T+2$ to buy the missing shares from the open market and deliver them to the buyer, charging the costs to the defaulting seller.
