What is Stock Lending and Borrowing (SLB)?

Stock lending and borrowing is a market practice that allows investors to temporarily lend or borrow shares for a fixed period. While it is not widely used by retail participants, it plays an important role in supporting short selling and settlement needs in the stock market. This mechanism is generally used by investors who understand market movements and are comfortable managing higher levels of risk. 

In India, SLB operates through the dedicated SLB segment of stock exchanges with screen-based order matching and is cleared through SEBI-recognised clearing corporations such as NSE Clearing Ltd and Indian Clearing Corporation Ltd (ICCL), which guarantee settlement.

Key Takeaways 

• Stock lending and borrowing allow the temporary transfer of shares without changing ownership, in return for a lending fee.

• The mechanism supports short selling and settlement needs while operating through regulated clearing systems.

• SLB contracts in India range from 1 month to 12 months with predefined reverse leg settlement dates.

• Only eligible securities such as F&O stocks, index ETFs, and clearing-corporation-approved shares can be lent or borrowed.

What is Stock Lending and Borrowing (SLB)? 

Stock Lending and Borrowing (SLB) in India takes place through a unique SLB segment available on recognised stock exchanges, where lending and borrowing orders are matched via a screen-based, anonymous order-matching system. Transactions are not handled directly between two investors, but rather via clearing corporations that serve as central counterparties. 

NSE Clearing Ltd and Indian Clearing Corporation Ltd (ICCL) are SEBI-recognised clearing corporations acting as central counterparties (CCPs). They ensure settlement guarantee, risk management, and collateral control. This approach decreases counterparty risk while also providing transparency, uniform contract terms, and safe settlement for lenders and borrowers in India's regulated SLB market.

How Does the SLB Mechanism Work? 

The stock lending and borrowing mechanism operates through clearing corporations that function under a regulated framework. The process is structured to ensure transparency, proper settlement, and risk control for both lenders and borrowers.

• Lending: Investors who hold shares in theirdemat accounts and do not plan to sell them immediately can offer these shares for lending for a fixed period.

• Borrowing: Borrowers, usually market participants with short-selling or delivery needs, borrow these shares by paying a lending fee.

• Contract terms: Each SLB contract clearly mentions the tenure, lending fee, and settlement conditions agreed at the time of the transaction.

• Settlement: On contract expiry, the borrowed shares are returned to the lender, and all obligations are settled as per the contract terms.

Reverse leg settlement in India happens on standard monthly settlement dates defined by the exchange. Early recall by the lender and early repayment by the borrower are also permitted under exchange rules. 

This structured process helps reduce counterparty risk and ensures compliance with market regulations.

What are the Benefits of Securities Lending and Borrowing? 

Securities lending and borrowing offer practical benefits to both lenders and borrowers when used with a clear understanding of risks. The mechanism helps improve market efficiency while allowing participants to use their holdings or strategies more effectively.

1. Additional Income 

Lenders can earn extra income by lending shares that they do not plan to sell in the short term. Instead of remaining idle, these holdings generate a lending fee during the contract period. This income can add to regular investment returns without changing ownership of the shares.

2. Convenience 

The lending and borrowing process is structured and rule-based, making participation relatively straightforward for eligible investors. Contracts clearly define tenure, fees, and settlement terms, which helps participants plan their positions without ongoing involvement during the lending period.

3. Short-Selling 

Borrowers can use borrowed securities to take short positions when they expect prices to fall. This allows them to act on market views without owning the shares upfront. Short selling through SLB also supports smoother settlements in the market.

4. Risk Mitigation

Transactions are carried out through a regulated clearing framework that requires collateral and predefined settlement rules. This structure reduces counterparty risk and helps ensure that obligations are met even if market conditions change during the contract tenure.

However, despite being available to all investors, SLB participation in India remains low, and the segment is relatively illiquid compared to cash and derivatives markets.

Why is it Riskier to Borrow Than to Buy? 

In SLB, borrowers must maintain margins that can be around 125% of the value of borrowed securities as prescribed by clearing corporations. They must also pay the lending fee along with applicable GST.

Suppose a trader buys the stocks of a hypothetical company called Platinum Tech. Immediately after the trader takes his position and gets a stake in the company’s future, the stock prices fall due to management changes. 

Now, this is contrary to the trader’s expectations, and his holdings have been devalued for sure. But the trader can wait out the recent management changes. If the fundamentals of Platinum Tech are solid, then the company will weather the storm, and its stock prices will likely go up again. The trader can clear his positions when the market changes course and the prices move favourably in his preferred direction.

As a borrower of stocks, though, a trader does not have the luxury to wait out any unexpected and unfavourable turn of events. Let’s take the example of another trader who borrows the stock of another hypothetical company, Gold Tech. The trader expects the stock price of Gold Tech to trend downward and hopes to make a profit by short-selling the stock.

Contrary to his expectations, Gold Tech goes on a bull run. Perhaps they introduce a new product that is a hit with a lot of people, and investors rush to put their money in this company. Now, this security lending and borrowing scheme is not working in the trader’s favour. As a borrower of stocks, our trader does not have the luxury to wait out this development. 

There is a tenure within which he must return the borrowed stock. Meanwhile, during the tenure, the trader must keep paying the applicable interest rate. Therefore, he will make a loss on two fronts. The upfront loss will be that of the interest paid to borrow the stock. If the trader sold the stock in the open market, hoping to buy it back at a cheaper rate, he will now need to buy it back at a higher rate since he needs to return the borrowed stock. That difference will be his secondary loss.

For the increased associated risks, stock lending and borrowing are practices normally seen among more experienced and more risk-tolerant traders.

Eligibility Criteria for SLB Participation 

To take part in stock lending and borrowing, investors must meet certain basic requirements. These conditions ensure that transactions are carried out smoothly and within the regulated market framework.

• Demat account: A valid demat account with an authorised depository is necessary to hold and transfer securities involved in SLB transactions.

• Trading account: Investors must have an active trading account to place lending or borrowing orders.

• Clearing corporation framework: All SLB transactions are routed through SEBI-recognised clearing corporations to ensure proper settlement and risk management.

• Eligible securities: Only shares that are part of the F&O segment, index ETFs, and other securities specifically approved by clearing corporations are eligible for SLB.

Meeting these criteria is essential before participating in the SLB mechanism.

Real-World Examples of SLB Transactions 

Consider an investor who holds 1,000 shares of a listed company and does not plan to trade them in the near term. Instead of keeping these shares idle, the investor lends them through the stock lending and borrowing mechanism for a fixed period. A borrower takes these shares for short selling and agrees to pay a lending fee of ₹10 per share.

At the end of the contract tenure, the borrower returns the same number of shares to the lender. During this period, the lender earns ₹10,000 as lending income without selling the shares or giving up ownership. This example shows how SLB can create additional income for long-term investors while allowing borrowers temporary access to shares for trading or settlement needs.

Conclusion 

In November 2025, the Securities and Exchange Board of India (SEBI) has announced a comprehensive review of the SLB and short-selling frameworks to enhance liquidity and align with international practices. However, no formal changes have been implemented yet.

Since SLB involves defined tenures, fees, and settlement rules, participants must clearly understand the risks and obligations involved. When used with proper awareness and risk assessment, stock lending and borrowing can serve as a practical tool within the broader securities market framework.
