Short Delivery
Short delivery occurs when a seller who has executed a trade in the equity cash market fails to deliver the required shares to the clearing corporation by the settlement deadline, triggering an auction process through which the exchange procures the shortfall securities on behalf of the affected buyer.
In the equity cash segment, once a trade is executed, the seller is obligated to deliver the exact number of shares sold by the pay-in deadline (T+1 by 10:30 am or 11:00 am under current SEBI norms for early pay-in, or the prescribed settlement date's cut-off). If the seller's demat account lacks the required securities on the settlement date—whether due to insufficient holdings, a failed pledge release, or administrative error—the clearing corporation records a 'short delivery' against that seller's position.
The clearing corporation then initiates a separate auction to procure the shortfall quantity. This auction, conducted on T+1 or T+2 depending on the segment and the nature of the short, invites other market participants to offer the shortfall securities at a price. The seller who caused the short delivery bears the cost of this auction, including any premium paid over the original trade price plus an exchange-levied penalty.
For the buyer whose trade was affected, there are two outcomes. If the auction succeeds in procuring sufficient shares, the buyer receives the securities through normal settlement channels. If the auction fails—meaning no one offers the shares, which can occur in circuit-locked or suspended stocks—the buyer receives a cash compensation instead. This compensation is calculated at the highest price of the stock over a specified lookback period or at a defined percentage premium, which is typically unfavourable compared to actually receiving the shares.
Short deliveries are most common in the case of shares that are in the physical settlement segment (formerly 'trade-to-trade'), where there is no netting of positions and every trade requires direct delivery. They also occur in situations where an investor sold shares expecting a pending corporate action credit (such as a bonus issue) that got delayed.
SEBI and exchanges track short delivery rates as a market quality metric. Persistent short delivery from a particular broker or in a particular security can trigger surveillance action. Clearing members are liable for the short deliveries of their clients and must fund the auction and penalty on behalf of those clients before recovering from them.
