14.16 Cash-market leverage in India: the Margin Trading Facility and pledged collateral
Motivation
Leverage in the Indian cash market does not come from a prime broker. It comes from two regulated arrangements: the Margin Trading Facility, in which the broker lends you part of the purchase price of delivery shares, and the margin pledge, in which shares you already own are pledged to the broker as collateral for margin. Both turn a price fall into a margin call at a level you can compute in advance (14.18). Most retail margin disasters are failures to do that computation.
A note on sources The rules below are quoted from the text of the SEBI master circular for stock brokers as reproduced in SEBI's consultation paper Review of Margin Trading Facility (MTF) framework (18 Jun 2026, https://www.sebi.gov.in/sebi_data/commondocs/jun-2026/Consultation%20Paper_p.pdf), which restates the framework in force before its proposals. Where a rule comes from a broker or news source it is marked as secondary. Rules change; check the current master circular on sebi.gov.in before relying on any of them.
14.16.1The Margin Trading Facility (MTF)#
Definition
Under MTF a stock broker funds part of a client's purchase of shares in the cash market. The shares bought (the funded stock) are pledged to the broker. The client pays an initial margin, the broker pays the rest and charges interest on the funded amount. There is no fixed tenure in the framework; the position can be held as long as margin is maintained (broker terms may add limits).
Eligible securities Equity shares and units of equity ETFs classified as Group I securities (the most liquid group, defined by impact cost and trading frequency in SEBI's liquidity categorisation).
Margin (paragraph 4.3 of the master circular as reproduced, 18 Jun 2026)
| Category | Applicable margin |
|---|---|
| Group I stocks available for trading in the F&O segment | VaR + 3 × applicable ELM |
| Group I stocks other than F&O stocks, and units of equity ETFs | VaR + 5 × applicable ELM |
Here VaR is the stock's VaR margin rate in the cash segment (a percentage derived from its volatility, recomputed by the clearing corporation) and ELM the extreme-loss margin rate, "as in the cash segment for a particular stock". The initial margin may be paid in cash, cash equivalents or equity shares, with haircuts as in SEBI's master circular on the cash-market risk-management framework. The circular further requires:
- funded stock and collateral to be held separately and marked to market daily;
- an increase in the value of collateral may support further exposure (after haircuts), but an increase in the value of funded stock may not;
- "maintenance of the aforesaid margin at all times"; in case of shortfall "stock broker shall make necessary margin calls";
- the broker to list in advance the conditions under which it will liquidate the client's securities; the exchange or broker may impose higher margins.
Brokers fund MTF from own funds, bank and NBFC borrowings, commercial paper and unsecured long-term loans from promoters and directors. The June 2026 consultation paper proposed, among other things, raising the minimum net worth of brokers offering MTF from ₹3 crore to ₹5 crore and keeping the margin requirements unchanged (as reported by Taxmann, June 2026; whether these proposals have been adopted was not verified as of 6 Nov 2026).
Arithmetic NSE's MTF FAQ illustrates with a stock whose VaR is 12.5% and ELM 5% (secondary: search summary of the NSE FAQ, not read in full): for an F&O stock the margin is , so the maximum leverage on fresh purchases is . For a non-F&O Group I stock with the same VaR and ELM it would be , leverage 2.67. VaR rates rise with volatility, so the permitted leverage falls exactly when prices are falling; 14.18 treats the margin rate as a variable for this reason.
Interest The broker sets the MTF interest rate, usually quoted per day. Rates in the low-to-mid teens per year annualised are common in broker rate cards, but this course has not verified a current schedule; use your broker's rate card. At 15% a year, a position held for 60 days pays 2.47% of the funded amount, which on a 2.5× levered position is a hurdle of about 1.5% of the position's value before any gain is yours.
14.16.2Pledging shares for margin#
Mechanics (secondary sources) Since the SEBI pledge/re-pledge framework (circular dated 25 Feb 2020, made mandatory from 1 Sep 2020 per broker notices), shares used as collateral stay in the client's demat account and are marked as pledged to the broker, who re-pledges them to the clearing corporation. The broker no longer holds client shares in its own pool. The collateral value is market value minus a haircut.
Haircuts Clearing corporations set haircuts for approved securities, aligned with the security's VaR margin rate, and publish them daily; brokers may apply larger ones (secondary: broker help pages and exchange approved-securities lists, 2025–26). For a large-cap stock the haircut is typically in the teens of percent; for a volatile small cap it can be 30–50% or the stock may not be accepted at all. Read the haircut on the day from your broker's approved-securities list; it changes daily.
The cash-component rule For derivatives margin, at least half of the margin must be in cash or cash equivalents; pledged equities can cover at most the other half (secondary: broker help pages; SEBI's collateral rules for the derivatives segment; verify with the exchange). A shortfall in the cash component attracts interest at most brokers.
What pledging does to risk Pledged collateral is leverage even when you never borrow cash: it lets you carry derivative positions whose losses are paid from cash you do not hold, against shares whose value falls in the same scenario. 14.18 shows that collateral correlated with the position moves the margin-call trigger much closer.
Promoter pledging is a different thing Promoters pledge shares to lenders to borrow against them; when the price falls, lenders invoke the pledge and sell, which pushes the price down further. It is a forensic red flag in M06 · 6.8 for the same reflexive reason as a retail margin call.
