The plain answer
Pledging shares puts them up as margin while you keep ownership. The pledge runs through the depository system with your TPIN, the shares stay in your demat account under a charge, and the margin value is the market value minus a haircut. The mechanics are simple; the risk is not: a pledged position that goes against you can be invoked and sold. This page explains the mechanics and the risk; it is not a strategy.
If you are a first-time investor, the honest summary comes before the mechanics: pledging exists to support leveraged trading, and leverage multiplies losses as efficiently as it multiplies buying power. Read the invocation section before the step-by-step section, because everything in between exists only to make invocation possible.

This page has three readers. The beginner reading out of curiosity gets the mechanics and the risk, and hopefully the conclusion that neither is needed yet. The holder who found a pledge they did not authorise on the CAS gets the verification trail and the dispute next step. And the trader who is already using margin gets the fee table, the haircut logic and the invocation sequence, spelled out without a sales pitch in either direction.
What a pledge is
A pledge is a charge over the shares in favour of the broker or lender, used as margin for leveraged positions. Ownership stays with you: dividends, bonus shares and corporate actions still reach you, and the pledge appears in your statements as a charge, not a transfer. The constraint is liquidity: pledged shares cannot be sold until unpledged, and the pledge value moves daily with the price.
The everyday analogy is the loan against property: the house stays in your name, the lender holds a charge, and a default lets the lender sell it. The demat version moves at trading speed instead of property speed, which is why the daily revaluation matters: the value of the collateral is re-checked against the obligation every single day, and a falling price shrinks the cover the lender holds.
What a pledge is not, and this matters for beginners: it is not free buying power, it is not a sale, and it is not reversible at will while the obligation it secured remains unpaid. The charge releases when the obligation closes, not when the holder would prefer it to.
| What the pledge allows | What the pledge blocks |
|---|---|
| Using the shares as margin | Selling the pledged shares until unpledged |
| Receiving dividends and corporate actions | Moving the shares to another account |
| Keeping the shares in your demat account | Unpledging while the secured obligation stays open |
| Releasing the charge by unpledging | Ignoring the daily revaluation of the margin value |
The same charge mechanism backs a second, quieter use: loans against securities, where a lender advances money against pledged holdings under its own loan terms. The mechanics are the same, the lender differs, and the loan’s terms, interest, tenure and recourse, are the lender’s product, not the depository’s. This page covers the trading-margin use; a loan against shares is a separate product with its own documentation.
The SEBI pledge system
Since September 2020, SEBI requires securities used as margin to be pledged through the depository system rather than handed over under power of attorney. The pledge is created with your TPIN, the charge registers in the depository’s records, and the shares never leave your BO account. Unpledging releases the charge. The system replaced the old arrangement precisely so that margin collateral stays visible in the holder’s own statements.
The design change was not cosmetic. Under the older power of attorney arrangement, a broker could act on standing authority over client holdings, and misuse of inactive accounts became one of the reasons SEBI moved against it. Under the pledge system, every charge is a per-transaction event authorised by your TPIN, recorded in the depository, and visible on your CAS. The authority for each pledge is yours, spent one pledge at a time.
The TPIN is the same code that authorises selling delivery shares and off-market transfers, covered in the TPIN guide. A pledge is simply another exit lane from your demat, so it passes through the same gate as every other debit.
For the holder, the system changed one thing that shows up every month: the pledge is a visible entry. It sits on your CAS and in the app’s holdings view as a charge against the pledged quantity, and the unpledge step removes it. Visibility is the point of the 2020 redesign, and it is also the check you should run: if a pledge appears that you did not authorise, treat it the way the compromised account guide treats any unexplained debit, immediately.
Creating a pledge, step by step
- You select the shares to pledge in the broker app
- You authorise the pledge with your TPIN
- The charge registers in the depository records
- The margin value credits to your trading account
- The value revalues daily as prices move
- Unpledging releases the charge and restores free balance
Two parts of that chain run without you after the first step. The daily revaluation is automatic: the depository recalculates the pledged value as prices move, and the broker tracks the cover against the obligation. And the unpledge step only works while the obligation it secured is settled, which is the constraint most first-time users discover too late.
The margin created by the pledge is not cash arriving in your bank. It is collateral value in the trading account that supports positions, typically leveraged ones. The distinction decides the whole risk profile: you are not receiving money, you are granting a claim over your shares in exchange for the ability to take positions larger than your cash.
The confirmation layer for every step of that chain is the statement. The pledge appears on the CAS and in the app’s holdings view as a charge against the pledged quantity, the daily revaluation shows as a changing margin value, and the unpledge removes the entry. Reconcile those entries the same way you would any other debit, because an unexplained charge in the statement is the earliest signal that a pledge happened that you did not authorise.
Haircuts
| Item | What it means |
|---|---|
| Haircut | The percentage the exchange deducts from market value for margin purposes |
| Typical range | 10% to 50%, set by volatility and liquidity |
| Effect | ₹1,00,000 of volatile stock may count for ₹70,000 of margin |
| Daily change | The pledge value recalculates as prices move |
The haircut is the exchange’s answer to a simple question: how much could this stock lose before the lender can act? A liquid, low-volatility stock loses less, so it carries a smaller haircut; a volatile or illiquid stock carries a larger one because the lender’s window of protection is narrower. The range in practice is typically 10% to 50%, and the exchange sets the number, not the broker.
Worked out: ₹1,00,000 of a stock with a 20% haircut creates ₹80,000 of margin. A 40% haircut creates ₹60,000. The haircut is not a fee, nothing is deducted from your holdings; it is the discount at which the market values your collateral, applied for margin purposes.
Why the exchange, and not the broker, sets the number: a centrally computed haircut, derived from each stock’s volatility and liquidity through the exchange’s risk parameters, means two brokers accept close to the same value for the same stock. The haircut is infrastructure, not negotiation, which is why the pledge value you see in one broker’s app will look familiar in another’s.
A worked example
You hold 1,000 shares of a company trading at ₹100, a holding worth ₹1,00,000. The exchange has set a 30% haircut on the stock. You pledge the holding, and the depository registers the charge: the margin value credited is ₹70,000, the market value minus the 30% haircut.
Now the price falls 20% to ₹80. The holding is worth ₹80,000, and the margin value falls with it, to ₹56,000. The obligation the pledge secured, say a leveraged position, must now be covered by a smaller collateral base. The gap between the obligation and the cover is the margin shortfall, and the broker asks you to cover it, with cash or additional margin, within the window it sets.
If the price falls further and the shortfall stays uncovered, the sequence ends in invocation: the lender exercises the pledge, the shares are sold to meet the dues, and the invocation charge applies. The example has no villain and no malfunction; every step is the structure working as designed. The question the example asks is only whether the shortfall gets covered before the last step.
| Aspect | Cash margin | Pledged margin |
|---|---|---|
| What it uses | Money you transfer | Securities you already hold |
| Ownership | Cash leaves your bank account | Shares stay in your demat under a charge |
| Value | Face value | Market value minus the haircut |
| Daily behaviour | Stable | Revalues as prices move |
| Worst case | You lose the cash you put up | The pledged shares are invoked and sold |
Margin shortfall and invocation
The obligation behind the pledge, usually a leveraged position, must stay covered. When the value of the position falls, the collateral value falls with it, and at some point the cover no longer matches the obligation. That gap is the margin shortfall. The broker then asks you to cover it, with cash or more margin, within a set window.
If the shortfall is not covered, invocation follows: the lender exercises the pledge, the shares are sold or taken to satisfy the dues, and the invocation charge applies. The sale happens at whatever price the system finds at the moment of invocation, not at a price you choose. That sentence is the entire risk of pledging, stated in one line.
The sequence, shortfall, demand, invocation, is the designed outcome of the structure, not a malfunction or a broker’s discretion. Every pledge exists so that invocation is possible; the only question is whether the shortfall gets covered before it happens. This page repeats the sequence twice because every leveraged loss story is this sequence once.
The daily rhythm behind that sequence is mark-to-market. The broker revalues the position against the day’s closing prices, recomputes the collateral cover, and raises a demand when the two no longer match. The demand is a request to restore the cover, usually with cash or additional collateral, within the window the broker sets. Prices moving against the position do not cause invocation directly; an unmet demand after the window does.
What it costs
| Cost | Amount | When it applies |
|---|---|---|
| Pledge request | ₹20 + GST per ISIN at Upstox | Each pledge request, per stock |
| Margin funding | Interest on the amount financed | While the leveraged position stays open |
| Invocation | A separate invocation charge | Only if the pledge is invoked |
| Unpledge | Usually no charge at most brokers | When the charge is released back to you |
The fee column is the easy part to read and the easy part to underestimate: the pledge fee is per request, so pledging five stocks costs five request fees, and the interest on margin runs every day the position stays open. Confirm the current numbers on the broker’s pricing page, because these are published charges, not negotiated ones.
Two ordinary trading costs sit beside this table unchanged: brokerage and statutory charges still apply on whatever positions the margin supports, and the DP charge still applies when securities are eventually sold. Pledging does not buy anyone out of the fee schedule; it adds rows to it. The cheapest pledge is the one never made, which is not a strategy point, it is a pricing point.
The risk, stated plainly
The pledge exists so the lender can invoke it. If the obligation behind the pledge is not met, the lender invokes, the shares are sold or taken, and the invocation charge applies. For a leveraged trader, invocation is the moment a losing position becomes a sold holding, at whatever price the system finds. That is why this page carries no strategy section: the pledge mechanics are public, the decision to use margin is personal, and the exchange’s own data on individual trader losses is the warning label.
For a first-time investor, the arithmetic of the decision starts from the daily revaluation. A leveraged position can lose faster than the underlying holding, because both the position and the collateral shrink together. The pledge does not cap the loss; it secures the lender against it. When the two conflict, the lender is paid first.
The residual question is what happens when the collateral itself runs out. If the obligation exceeds the value of the pledged shares, invocation covers what it covers, and the shortfall that remains is the trader’s to pay. That sentence is the true outer boundary of pledging: the shares at risk are not the maximum loss, they are the lender’s floor, and everything below the floor still belongs to the account holder.

What people usually get wrong
Pledging transfers my shares to the broker
The shares stay in your BO account under a charge. Ownership, dividends and corporate actions remain yours.
The full market value becomes margin
The haircut reduces the margin value, and the exchange sets the haircut. Full value was never the rule.
Pledging is free
Pledge requests carry a charge (₹20 + GST per ISIN at Upstox), and invocation carries its own fee. The costs are published on the pricing page.
I can pledge and sell the same shares
Pledged shares are blocked from sale until unpledged. Unpledge first, then sell, and the obligation behind the pledge must be settled before the release.
Questions people ask
No. Pledge is a charge over the shares, not a transfer. You keep ownership and receive the corporate actions; the pledge appears in your statements. What you lose is the ability to sell the pledged shares until the pledge is released. The charge is visible in the depository records the entire time it exists.
The market value minus the exchange-set haircut, which varies by stock volatility and liquidity. A ₹1,00,000 holding might count for ₹70,000 to ₹90,000 of margin depending on the stock. The pledged value recalculates daily as prices move. The haircut is set by the exchange, not the broker, so two brokers accept roughly the same pledge value for the same stock.
Invocation is when the lender exercises the pledge, typically because an obligation was not met. The shares are then sold or taken to satisfy the dues, with an invocation charge applied. Invocation is the event every pledge structure is built to allow, which is why the risk section below matters. The trigger is usually a margin shortfall that is not covered within the time the broker allows.
Pledged shares cannot be sold until unpledged. Unpledging releases the charge and restores the shares to free balance, usually without a TPIN at most brokers because the shares are moving back to you. The pledge must also be closed against the obligation it was taken for, which means the margin position behind it has to be settled first in most flows.
The pledge request carries a fee: ₹20 + GST per ISIN per request at Upstox. Invocation carries its own charge, applied when the lender exercises the pledge. The margin itself usually carries an interest cost on the amount financed, charged while the leveraged position stays open. All three costs are published on the pricing page, and all three apply on top of the ordinary trading costs.
The broker asks you to cover the shortfall, usually with cash or additional margin, within a set window. If the shortfall remains, the lender invokes the pledge: the shares are sold or taken to meet the dues, and the invocation charge applies. That sequence is the designed outcome of the pledge structure, not a malfunction, which is why the decision to pledge should start with this paragraph, not end with it.
