Securities Lending and Borrowing is a mechanism through which investors can borrow or lend shares to other market participants.

What is Securities Lending and Borrowing mechanism?

Securities Lending and Borrowing is a mechanism through which investors can borrow or lend shares to other market participants. The platform provides a viable alternative to derivatives market for purposes of hedging. Borrowers in SLB are usually short-sellers i.e. traders who want to sell shares that they don’t own. Lenders on the other hand are those investors who have bought shares for long-term purposes and such shares are lying idle in their demat accounts. Securities lending is a temporary lending of securities by a lender to the borrower. This mechanism provides liquidity to the equity market and thereby increases the market efficiency

Why Securities Lending and Borrowing mechanism?

Just like a loan you avail from a bank, if you have borrowed the shares from another investor, an interest has to be paid for the lender. The interest rate varies from stock to stock and also depends on tenure of such borrowings. As per SEBI rules, the tenure for lending and borrowing is available for maximum period of 12 months. The lending rate for such lending is not fixed but is determined by the market conditions.

Understanding Short Selling

A short sale involves the sale and buyback of borrowed securities. The goal is to sell the securities at a higher price, and then buy them back at a lower price. These transactions occur when the securities borrower believes the price of the securities is about to fall, allowing him to generate a profit based on the difference in the selling and buying prices. Regardless of the amount of profit, if any, the borrower earns from the short sale, the agreed-upon fees to the lending brokerage are due once the agreement period has ended. The Securities Lending and Borrowing mechanism allows short sellers to borrow securities for making delivery.
