India Has ₹1.55 Lakh Crore of Borrowed Money Long a Falling Market. That Is the MTF Book.
Margin Trading Facility has gone from ₹24,920 crore to ₹1.55 lakh crore in three years while Nifty went nowhere. What MTF actually is, what 4x leverage does to a 20% fall, what holding it really costs, and what SEBI is about to change.
Margin Trading Facility lets you buy shares with money your broker lends you — roughly 4x your cash on many stocks, at 14.6% to 18.25% a year. India's MTF book hit a record ₹1.55 lakh crore on 21 September 2026, up from ₹24,920 crore in FY23. Over the last twelve months Nifty returned −4.38% while that borrowed pile grew 65%. About half of it sits in non-F&O mid and small caps — which is exactly what fell 3.65% today. This post is the arithmetic: what 4x does to a 20% drawdown, what holding actually costs once interest and pledge fees are counted, and what happens in the minutes before a broker squares you off.

Every leveraged blow-up in market history has the same shape. Borrowing grows quietly through a good stretch, nobody minds because the borrowing is winning, and then the market falls far enough that the borrowed positions have to be sold — which makes the market fall further, which forces more selling. Nothing about it is exotic. It is arithmetic with a deadline attached.
India currently has ₹1.55 lakh crore of that arithmetic outstanding, and almost nobody outside broker risk desks is watching the number. So here it is, along with the part that actually matters to you: what it does to your account.

fear gauge — rises when leverage unwinds
- MTF is a loan from your broker to buy delivery shares. You put up a margin, the broker funds the rest, the shares are auto-pledged as collateral, and interest runs from T+1 until you sell.
- Typical leverage is about 4x on non-F&O stocks (VAR + 5× ELM) and less on F&O names (VAR + 3× ELM). At 4x, a 25% fall in the stock wipes out 100% of your money.
- Interest is 0.04% to 0.05% per day — 14.6% to 18.25% a year. A stock has to rise by more than that annually before the trade makes you anything.
- India's MTF book hit ₹1.55 lakh crore on 21 September 2026, against ₹24,920 crore in FY23. Roughly half sits in non-F&O mid and small caps, the least liquid half of the market.
- SEBI's permitted ceiling is MTF exposure of 500% of a broker's net worth, and some brokers are running close to it. Its 2026 consultation proposes capping exposure at 5.5× net worth and raising the minimum net worth from ₹3 crore to ₹5 crore.
What MTF actually is
Margin Trading Facility is your broker lending you money to buy shares in the delivery segment. You bring part of the money, the broker brings the rest, and you keep the shares — but not freely. They are automatically pledged to the broker as collateral the moment you buy, and unpledged when you sell.
It is marketed as "pay later" or "4x buying power", which is accurate and also the least useful way to describe it. The honest description is: an unsecured-feeling loan secured by the very asset whose price decides whether you can repay it.
MTF against the two things people confuse it with:
| MTF | Futures | Cash delivery | |
|---|---|---|---|
| What you own | Actual shares, pledged | A contract, not shares | Actual shares, free |
| Leverage | ~4x (non-F&O), less on F&O names | ~5-7x via SPAN margin | None |
| Cost of carry | Interest, 14.6-18.25% p.a. | Built into the futures premium | Nil |
| Expiry | None — hold indefinitely | Monthly, forced exit | None |
| Universe | Broker's approved list, incl. non-F&O stocks | F&O stocks only (~220) | Everything |
| Dividends / bonus | Yours | Not yours | Yours |
| Who decides you exit | The broker can square off | Exchange margin rules | Only you |
That last row is the one to sit with. In cash delivery, a 40% fall is painful and entirely your decision to endure. In MTF, someone else decides — and they decide based on their risk, not your conviction.
The arithmetic of 4x
Leverage is usually explained with the upside. Here is the whole distribution. Say you have ₹1,00,000 and buy ₹4,00,000 of a stock at 4x. Ignore costs for a second — we add them back below.
₹1,00,000 of your money, ₹4,00,000 of stock:
| Stock moves | Position value | Your equity | Your return |
|---|---|---|---|
| +25% | ₹5,00,000 | ₹2,00,000 | +100% |
| +10% | ₹4,40,000 | ₹1,40,000 | +40% |
| +5% | ₹4,20,000 | ₹1,20,000 | +20% |
| −5% | ₹3,80,000 | ₹80,000 | −20% |
| −10% | ₹3,60,000 | ₹60,000 | −40% |
| −15% | ₹3,40,000 | ₹40,000 | −60% · margin call territory |
| −25% | ₹3,00,000 | ₹0 | −100% · you are wiped out |
A 25% fall is not a crash. The Nifty Midcap index fell 3.65% in a single session today. A mid-cap stock down 25% from where you bought it is an ordinary quarter in an ordinary correction — and at 4x it is the end of your capital, with the broker still owed its ₹3,00,000.
You will not actually reach −25% in the account, because you will be squared off well before it. That is the mechanism working as designed. It is also why the leverage number and the "I will just hold until it recovers" plan cannot both be true.
Same idea, different instrument — see how fast a leveraged position reprices:
The asymmetry is structural, not bad luck: +25% doubles you, −25% erases you. Leverage does not change your odds of being right. It changes what being wrong costs.
What it actually costs to hold
The headline rate is 0.04% per day at the cheaper brokers, which is about 14.6% a year. Groww quotes 14.95%. Across the industry the range runs to 0.05% a day, or 18.25% annualised. Interest accrues from T+1 and keeps accruing every single day until you sell — weekends and holidays included.
Real cost on ₹3,00,000 of borrowed money at 0.04%/day:
| Held for | Interest | Stock must rise by | Just to break even |
|---|---|---|---|
| 1 week | ₹840 | 0.28% | on the ₹4 lakh position |
| 1 month | ₹3,600 | 0.90% | |
| 3 months | ₹10,800 | 2.70% | |
| 6 months | ₹21,600 | 5.40% | |
| 1 year | ₹43,800 | 10.95% |
Read the one-year row again. On your ₹1,00,000 of actual capital, a year of MTF interest is ₹43,800 — 43.8% of your own money, paid regardless of what the stock does. The position has to gain nearly 11% before you have made a single rupee, and if it goes sideways for a year you have lost close to half your capital to interest alone while the stock did nothing wrong.
And the charges that do not appear in the headline rate:
- Pledge fee — around ₹15 + GST, once per day per stock, because MTF shares are pledged automatically on purchase.
- Unpledge fee — around ₹15 + GST for each distinct day on which the shares you are selling were bought.
- Square-off charge — around ₹50 + GST per order when the *broker* closes your position rather than you. Worst possible moment to pay a fee.
- Brokerage — normal delivery brokerage still applies on both legs.
None of these are large individually. Together, on a small position held a few weeks, they can consume a meaningful share of a winning trade — and they are charged on losers too.
What actually happens in a margin call
This is the part worth understanding before you need it, because the documentation is deliberately vague and the vagueness is not in your favour.
When the stock falls, the collateral value falls with it, and your account develops a margin shortfall. You are expected to top it up — with cash or additional pledged collateral. If you do not, the broker may sell your shares. Zerodha's own FAQ puts it as: if the account goes into negative due to losses, the broker "may square off the position". Which positions, in what order, and at what time is the broker's discretion, not yours.
What that means in practice:
- No fixed deadline is published. Brokers act on their own risk policy, and that policy tightens when the market is falling — which is when you most need time.
- The broker sells to protect the broker. It may liquidate your best holding because it is the most liquid, not your worst.
- Square-off happens at market, into a falling market, often near the close. You do not choose the price.
- You pay the square-off fee for the privilege.
- Any shortfall after liquidation is still your debt. The loan does not vanish because the collateral did.
If you are holding MTF, find your broker's actual margin-call policy today — the timeline, the notification method, the order of liquidation. Do it while the position is comfortable. Nobody has ever read a risk policy carefully on a red day.
The number that should worry you more than the size
₹1.55 lakh crore is a big number, but size alone is not the risk. Composition is. Roughly half of MTF exposure sits in non-F&O stocks — mid and small caps with no derivatives market, thinner order books and wider spreads.
That matters for one reason: an F&O stock can be hedged. A broker unwinding a position in a liquid large cap has a futures market to lean on and depth to sell into. A broker unwinding ₹50 crore of a small cap that trades ₹8 crore a day has neither. It simply sells, and the price goes where it goes. Everyone else holding that stock on margin then gets a little closer to their own call.
Note too that non-F&O stocks are precisely where the *higher* leverage is available — VAR + 5× ELM against VAR + 3× ELM for F&O names. The most leverage is offered on the least liquid stocks. That is not a conspiracy; it falls out of how the margin formula is built. It is still worth knowing that the structure quietly points retail money at the thinnest end of the market.
Today's session is the illustration. Nifty fell 1.64%. The Midcap index fell 3.65% — more than twice as much — and India VIX jumped over 15%. Whatever is under stress today, it is not the large caps.

How exposed are the brokers themselves?
SEBI currently permits a broker to run an MTF book of up to 500% of its net worth. That is a lot of borrowed money standing on a little capital, and reporting through 2026 suggests some brokers are operating close to that ceiling. Zerodha has disclosed a book at roughly 25% of net worth. The spread between those two postures is enormous, and it is not disclosed in any way a retail customer would naturally see.
Why you should care even if you never use MTF: a broker whose book is near the cap has far less room to absorb a bad week, and the pressure to liquidate customer positions quickly is correspondingly higher. Your square-off timeline is a function of your broker's balance sheet, not only of your own position.
What SEBI is changing
SEBI ran a consultation on the MTF framework with comments closing on 9 July 2026. The proposals read like a regulator that has noticed the growth chart.
Proposed changes and what each one is for:
| Proposal | What changes | What it is aimed at |
|---|---|---|
| Minimum net worth ₹3 cr → ₹5 cr | Fewer, better-capitalised brokers may offer MTF | Thin-capital brokers running large books |
| Exposure capped at 5.5× net worth | A hard multiple, with capital ring-fenced for core broking | The gap between the 500% ceiling and prudence |
| Wider collateral accepted | Anything valid in the cash market; G-secs, MFs, ETFs | Reducing concentration in the funded stock itself |
| Higher maintenance margin in some cases | When cash collateral and bought shares both serve as collateral | Double-counting of the same risk |
| 30 days to rebalance | When a stock loses eligibility or exits Group-I | Forced fire-sales on a technicality |
| NCDs and debt as funding | Brokers can fund MTF beyond bank and NBFC loans | Funding concentration risk |
Separately, the RBI's revised collateral framework from 1 July 2026 requires 100% cash or cash-equivalent collateral for broker borrowing, with a minimum 40% haircut on equity collateral. In plain terms: it just got more expensive for brokers to fund these books. That cost does not stay with the broker.
Our read: the 5.5× cap is the meaningful one. Everything else is housekeeping. If it lands as proposed, brokers running near 500% of net worth have to shrink — and shrinking an MTF book means customer positions get closed, whether or not those customers did anything wrong. Worth knowing which kind of broker you are with before that circular arrives.
If you are already holding MTF
Five things worth doing this week, none of which require a view on the market:
- Work out your actual leverage. Position value divided by your own money in it. If it is above 2x on a mid cap right now, you are taking a risk most people at that ratio have not modelled.
- Calculate your wipe-out level. 100 divided by your leverage, as a percentage fall. At 4x it is 25%. At 3x it is 33%. Write the actual price down. Look at it.
- Add up the interest you have paid so far. Days held × 0.04% × funded amount. For many people this is the moment the trade stops looking clever.
- Read your broker's margin-call policy. Timeline, notification, liquidation order. Today, not on the day it triggers.
- Decide your exit before the broker decides it for you. A position you close yourself is a decision. One the broker closes is a fee plus whatever price the market felt like.
And the uncomfortable general point: leverage is not a way to make a small account big. It is a way to make a small account reach its outcome faster, in whichever direction it was already heading. If the underlying strategy is not profitable unlevered, 4x does not fix it — it just shortens the time to zero. We wrote about the mathematics of that in risk of ruin, and it applies here more directly than anywhere else on this site.
Nothing here is a recommendation to use or avoid MTF, or a view on any stock. It is the cost structure and the failure mode, written out, so the decision is yours and informed rather than yours and optimistic.

Frequently Asked Questions
What is MTF in the stock market?
Margin Trading Facility is a loan from your broker to buy delivery shares. You put up part of the money, the broker funds the rest, and the shares are automatically pledged to the broker as collateral. Interest accrues daily from T+1 until you sell. It is offered as "pay later" or "4x buying power".
What is the interest rate on MTF in India?
Typically 0.04% per day at the cheaper brokers, about 14.6% a year. Groww quotes 14.95% a year. Across the industry rates run up to 0.05% a day, roughly 18.25% annualised. Interest is charged every calendar day the position is open, including weekends and holidays.
How much leverage does MTF give?
Around 4x on many non-F&O stocks, where the margin is VAR + 5× ELM, and less on F&O stocks, where it is VAR + 3× ELM. The exact figure varies per stock and per broker. Note that the higher leverage is available on the less liquid non-F&O names.
What happens if my MTF position falls?
Your collateral value falls with it and the account develops a margin shortfall. You are expected to add cash or collateral. If you do not, the broker may square off your positions — choosing which ones, in what order and at what time at its own discretion, typically at market into a falling market, plus a square-off charge of around ₹50 + GST per order. Any shortfall remaining after liquidation is still your debt.
At what fall does 4x MTF leverage wipe out my capital?
A 25% fall in the stock. At 4x, ₹1,00,000 of your money controls ₹4,00,000 of stock; a 25% fall costs ₹1,00,000, which is all of your equity. In practice the broker squares you off before that point. The general rule is 100 divided by your leverage — 33% at 3x, 50% at 2x.
How big is India's MTF book?
A record ₹1.55 lakh crore as of 21 September 2026 — ₹1.48 lakh crore on NSE and ₹6,852 crore on BSE. That compares with ₹24,920 crore in FY23, roughly a sixfold rise in under three years, while Nifty returned −4.38% over the trailing twelve months.
Is MTF safer than futures?
Different, not safer. MTF gives you the actual shares with no expiry, so there is no forced monthly roll and you keep dividends. But it carries an explicit interest cost of 14.6-18.25% a year, it is available on illiquid non-F&O stocks where futures are not, and the broker can liquidate you at its discretion. Futures have expiry and exchange-set margins but no separate interest line.
What is SEBI changing about MTF?
A 2026 consultation, with comments closed on 9 July 2026, proposes raising the minimum broker net worth from ₹3 crore to ₹5 crore, capping total MTF exposure at 5.5 times net worth, widening acceptable collateral, allowing 30 days to rebalance when a stock loses eligibility, and permitting NCD funding. The existing permitted ceiling is 500% of broker net worth. Separately, the RBI's collateral framework from 1 July 2026 raises the cost of broker borrowing.
