SLB mechanism allows short sellers to borrow securities for making delivery.
The rollover facility in the SLB session will be available for a three-month period (original contract plus two rollover contracts).
Under the rollover facility, lenders of securities would be allowed to extend an existing position. It means that lenders who are due to receive securities can now extend the period of lending.
Similarly, a borrower who has to return borrowed securities can extend the period of borrowing.
Currently, the country's SLB market is very shallow. In April, this segment's turnover was Rs 322 crore.
In November 2012, capital markets regulator Sebi had allowed rollover facility in SLB scheme.
