SLBM (Securities Lending and Borrowing Mechanism/Scheme) lets an investor temporarily lend eligible dematerialised securities through an exchange-cleared mechanism and receive a market-determined lending fee.
The borrower gets the securities for a defined period and must return equivalent securities.
The lender does not sell the investment merely by lending it under the approved scheme, but the investor must understand tenure, recall rules, corporate actions, broker charges, demand for the stock and tax treatment of the lending fee.

SLBM participation depends on the investor’s broker and securities holdings, so the demat account guide is useful for reviewing account-service considerations.
What Is SLBM?
SLBM is the exchange-cleared framework for lending and borrowing securities in India. In practical terms, one investor temporarily lends securities in a demat account, while another market participant borrows them for a specified period.
The borrower pays a lending fee, and the clearing framework returns the securities at the end of the contract or earlier, as permitted.
NSE Clearing operates as an Approved Intermediary for its SLB segment. Orders are matched on an automated screen-based platform using price-time priority.
The quoted price in an SLB order is the lending fee per share – not the market price of the underlying share.
Why Would Anyone Borrow Shares?
- To meet delivery obligations or settlement needs.
- To implement a short-selling or arbitrage strategy within the permitted market framework.
- To hedge another exposure.
- To exploit a price difference between cash and derivatives markets.
- To support market-making or other legitimate trading strategies.
For a long-term investor, the key point is that borrower demand creates the possibility of earning a lending fee on securities that might otherwise remain idle.
But there is no assurance that a particular stock will have borrower demand on the date you want to lend it.
How Does a Lender Earn Money?
The borrower pays a lending fee determined in the SLB market. If the market fee is Rs. 6 per share and you lend 1,000 shares, the gross lending fee is Rs. 6,000 before broker/participant charges and tax effects.
The market can quote very different fees for different securities and contract tenures because borrowing demand varies.
NSE also displays an annualised yield field for SLB market data. Treat that as a way to compare lending economics across tenures, not as a fixed deposit-like return.
You earn only when your lend order actually matches, and future lending demand may disappear.
Who Can Participate in SLBM?
The SEBI framework allows broad categories of market participants, including retail investors, to lend or borrow through authorised participants.
In practice, a retail investor accesses SLBM through a broker or participant that supports the segment.
Not every retail broker offers the same front-end experience, supported stocks, order controls or fee schedule, so the first operational question is whether your broker provides SLB access.
Which Shares Can Be Lent?
Eligibility depends on the exchange/clearing framework and can change.
NSE Clearing states that securities available in the F&O segment, index-based ETFs, liquid ETFs, and certain Group 1 securities meeting SEBI-defined criteria may be permitted.
Check the live eligible list on the exchange or through your broker before placing an order.
Do not assume: Owning a listed share does not automatically mean it can be lent through SLBM. Eligibility and active borrow demand are separate conditions.
SLBM Tenure: Monthly Contracts and the New R3 Series
Historically, NSE SLB has offered monthly series with specified reverse-leg settlement dates, extending up to 12 months.
The reverse-leg settlement date for monthly contracts is generally the first Tuesday of the relevant series month, subject to exchange rules and calendars.
From August 17, 2026, NSE added an R3 series. The exchange notes that the reverse-leg settlement date for R3 is T+3.
This matters because it gives investors a much shorter contractual window when this series is available, rather than forcing every lending decision into a longer monthly structure.
| Feature | Monthly SLB series | R3 short-tenure series |
| Typical structure | Fixed monthly reverse-leg date | Reverse leg on T+3 |
| Potential use | Longer borrow/lend demand | Short-duration requirement |
| Income visibility | Depends on matched lending fee | Depends on matched lending fee |
| Availability | Subject to eligible stock and demand | Subject to exchange eligibility and availability |
| Main risk for lender | Recall/market opportunity/corporate-action mechanics | Same categories, but shorter duration |
Step-by-Step: How Share Lending Typically Works
- Activate SLB with a supporting broker. Complete any broker-specific consent, documentation or segment activation.
- Check whether your stock is eligible. Use your broker interface or the exchange’s eligible-securities report.
- Choose the series/tenure. Select an available monthly series or, where available, the shorter R3 contract.
- Quote the lending fee. The SLB order price is the per-share fee you want to receive.
- Order gets matched. Matching occurs using the exchange mechanism.
- Deliver securities for the first leg. NSE Clearing states that lender securities are due for first-leg settlement on T+1.
- Receive lending fee according to settlement. Your broker/participant passes through the applicable proceeds after its charges.
- Receive equivalent securities back. The borrower returns securities on the reverse-leg settlement date, subject to recall/repayment and clearing rules.
Can the Lender Recall Shares Early?
Yes, the SLB framework provides lenders with an early recall facility and borrowers with an early repayment facility. However, early recall is not simply a free instant cancellation.
The SLB order-matching framework handles it, and the economics of the remaining lending fee are market-determined.
Investors should understand their broker’s interface and the exchange process before treating SLBM as “shares available anytime without friction.”
What Happens to Dividends and Stock Splits?
Corporate actions are one of the most important practical questions. NSE Clearing states that, in the case of a dividend, the borrower pays the dividend amount to the lender.
For a stock split, the borrower position is adjusted proportionately, and the lender receives the revised quantity on the reverse-leg settlement date.
Other corporate actions can lead to foreclosure of SLB positions on the ex-date. In those situations, the framework can also require pro-rata adjustment of lending fees.
This is why you should not ignore the corporate-action column in live SLB market data.
| Corporate action | Typical SLB treatment described by NSE Clearing |
| Dividend | Dividend amount collected from borrower and passed to lender |
| Stock split | Borrower position adjusted; lender receives revised quantity |
| Other corporate actions | Existing positions may be foreclosed on ex-date |
| AGM/EGM | Treatment depends on contract series |
Charges in SLBM
The exchange mechanism defines the lending fee, settlement and margin framework, but the actual cost visible to a retail investor can also include broker/participant charges, exchange/clearing charges, GST on service charges and other applicable levies.
Because broker pricing varies, there is no universal “SLBM charge” that can be quoted for every retail account.
Before lending, ask your broker for a complete tariff example showing gross lending fee, each deduction and the net amount credited to you.
A high headline annualised yield can look much less attractive after short-tenure costs if the gross fee is small.
How Is SLBM Taxed in India?
Two tax points are relatively clear from the official framework.
First, CBDT clarified that lending/borrowing of securities under the approved SEBI scheme falls under Section 47(xv), so the lending transaction itself is not treated as a taxable transfer in the lender’s hands merely because the security was lent.
Second, the CBDT circular states that the lending and borrowing transaction itself is not subject to Securities Transaction Tax (STT).
The lending fee an investor receives is still income. The precise head of income and deductibility of related expenses can depend on facts such as whether you are an investor or carrying on a securities business.
The lending fee received through SLBM is income, but its appropriate tax classification can depend on the investor’s circumstances.
Investors should confirm the applicable treatment with a tax professional rather than assuming that the lending fee is tax-free.
Tax caution: Do not confuse “SLB lending is not treated as a transfer” with “the lending fee is tax-free.” Those are different questions.
What Are the Risks for a Share Lender?
- No borrower demand. Your stock may be eligible but still have little or no attractive demand for lending.
- Opportunity cost. While the shares are in an SLB contract, your ability to act instantly on a market view can depend on recall mechanics and timing.
- Corporate-action complexity. Certain actions can trigger adjustments or foreclosure.
- Operational/broker risk. You rely on your participant to process orders, settlements and credits correctly.
- Fee volatility. A high lending fee today says nothing about next month.
- Tax and record-keeping. Frequent lending can create additional reconciliation work.
- Settlement failure handling. Clearing arrangements reduce bilateral counterparty exposure, but shortages can still lead to auction/financial close-out processes rather than the simple return path investors imagine.
Illustrative SLBM Income Example
Assume you own 500 shares of Company A. A lend order matches at Rs. 8 per share for a particular SLB series. Your gross lending fee would be Rs. 4,000.
If your broker and applicable service charges total Rs. 450, your pre-tax net receipt becomes Rs. 3,550. The tax on that income depends on your tax profile and classification. If no borrower matches your order, your lending income is zero.
This is why investors should view SLBM as an opportunistic yield-enhancement tool for eligible idle holdings, not a dependable monthly-income product.
SLBM vs Simply Holding Shares
| Issue | Hold shares normally | Lend through SLBM |
| Potential extra income | None beyond normal investment return/dividend | Possible market-determined lending fee |
| Share ownership exposure | Normal holding | Economic holding continues, but securities are temporarily lent under scheme |
| Dividend handling | Direct corporate action credit | Dividend compensation is passed through via clearing mechanism |
| Liquidity to sell immediately | Normal, subject to market | May require recall/contract handling |
| Complexity | Low | Higher |
| Income certainty | No lending income | No guarantee of matching or future fee |
Frequently Asked Questions
Can retail investors use SLBM in India?
Yes, the regulatory framework permits broad investor participation, but you need access through a broker/participant that supports the SLB segment.
How much can I earn by lending shares?
There is no fixed rate. The fee is discovered in the SLB market and varies by stock, demand and contract tenure. An order must match before you earn anything.
Do I lose the dividend if I lend shares?
NSE Clearing states that, under the SLB framework, dividend amounts are collected from the borrower and paid to the lender.
Can I recall lent shares?
The framework provides an early recall facility, but it operates through the SLB mechanism, and the economics of the remaining fee are market-determined.
Is SLBM taxable?
The lending transaction itself is not treated as a transfer under the approved scheme and, according to CBDT guidance, is not subject to STT.
The lending fee is income and should be reported under the appropriate tax treatment for your facts.
What changed in SLBM in 2026?
NSE introduced the R3 short-tenure series effective August 17, 2026, with reverse-leg settlement on T+3, alongside the established monthly series.
Lending fees and gains on the underlying shares may require different tax analysis; the stock market tax guide explains the usual categories of securities income.
Conclusion
SLBM can turn an otherwise idle eligible holding into an additional source of market-linked income, but the product isn’t automatic, and the fee isn’t guaranteed.
The most useful way to evaluate SLBM is stock by stock: check eligibility, live borrow demand, fee, tenure, broker deductions, recall flexibility, corporate actions and tax reporting.
For long-term shareholders who understand these mechanics, it can be a useful portfolio tool rather than a reason to buy a stock in the first place.
