Retail India has ₹1.47 lakh crore of stocks bought on borrowed money. As of 22 Oct, those positions are sitting on a ₹15-16k Cr paper loss. This analysis goes through all stocks in NSE’s margin-trading (MTF) data to see what’s inside: how the book was built, where the losses sit, and whether the unwind has started.
Under the Margin Trading Facility, you put in ₹25k, the broker lends ₹75k, and you own ₹1 lakh of stock. That leverage magnifies gains and losses alike:
On top of that, interest runs at 9–20% a year the whole time.
The combined MTF book (NSE + BSE) grew sharply this year:
| Date | MTF Book (NSE + BSE) |
|---|---|
| 30 Mar 2026 | ₹1.10 lakh Cr |
| 30 Sep 2026 | ₹1.59 lakh Cr (all-time high) |
That is +45% in 6 months. The book hit its record right as the market was rolling over.
Here is how the indices and the MTF book moved since 1 Sep:
| Since 1 Sep | Change |
|---|---|
| Nifty 50 | −6% |
| Midcap 100 | −14% |
| Smallcap 100 | −11% |
| MTF book | −0.2% |
Prices fell, but the borrowing didn’t. On 15 of 34 sessions, the book grew while Nifty fell. That’s traders averaging down with borrowed money.
Of ~2100 stocks with clean data:
Net paper loss: −₹15-16k Cr
| Depth of Loss | Number of Stocks | Positions |
|---|---|---|
| More than 20% underwater | 442 | ~₹30k Cr |
| More than 30% underwater | 122 | ~₹6k Cr |
At those levels, most leveraged holders have already had margin calls.
The stocks carrying the biggest MTF paper losses are:
74 PSU stocks carry ₹21-22k Cr of leveraged positions. The 2024 favourites are now the most-borrowed-against losers.
| Segment | Average Distance from Buy Price |
|---|---|
| PSU stocks (74) | −15-16% |
| Rest of the book | ~-10% |
| Railways | ≈ −25% |
| PSU finance | ≈ −21.5% |
354 stocks priced under ₹50 hold ~₹8k Cr of MTF. A cheap share price does not mean cheap risk.
One way to track this is the ratio of new positions opened per ₹1 closed:
| Period | New Positions per ₹1 Closed | What It Means |
|---|---|---|
| Sep | 1.07 | Leverage being added (+₹5,278 Cr) |
| Oct | 0.91 | Leverage coming off (−₹4,630 Cr) |
| 21–22 Oct | 0.74 and 0.73 | First back-to-back days below 0.75 since 1 Sep |
On 22 Oct, the leveraged book fell 1.1%, while Nifty fell only 0.5%. Nifty fell further on 23 Oct, but the latest available data is for 22 Oct.
Until then, small & midcaps carry a ₹20-25k Cr overhang of stressed positions.
