BSE Clearing launches 3-day SLB contracts

On August 17, 2026, BSE Limited — BSE Clearing Limited, the clearing corporation of the Bombay Stock Exchange, launched three-working-day contracts in its Securities Lending & Borrowing (SLB) segment. The new contracts feature a T+1 first leg and a T+3 reverse leg, excluding settlement holidays, and are initially available for securities in the F&O segment under the 'D' series prefix. The shorter tenor aims to provide greater flexibility for short-term securities borrowing and delivery requirements, facilitate inter-exchange arbitrage, and improve price alignment across trading venues. The initiative builds on the flexibility provided under SEBI's SLB framework. The contracts will not have foreclosure in the event of AGM or EGM, and will not offer facilities for repayment, recall, or rollover. The SLB platform continues to operate through an automated, screen-based order matching mechanism based on price-time priority. Vaisshali Babu, MD & CEO of BSE Clearing, stated that the introduction of shorter-tenor SLB contracts is an important step towards making the securities lending ecosystem more responsive to the evolving needs of market participants. National Stock Exchange of India — NSE Clearing Limited had earlier announced the introduction of similar shorter-tenure contracts under the SLB Scheme from August 17.
