SEBI Margin Trading Facility norms: minimum collateral, leverage limits, and broker square-off mechanics

Margin Trading Facility (MTF) is the only regulator-sanctioned way for a retail investor to take a leveraged cash-market position in Indian equities outside the derivatives segment. Brokers fund part of the buy value, the client puts up the rest as initial margin, and the funded shares sit in the demat account with a margin pledge tag. The framework is governed by SEBI Circular CIR/MRD/DP/54/2017 dated 13-June-2017, with the pledge mechanics overhauled by SEBI Circular SEBI/HO/MIRSD/DOP/CIR/P/2020/28 dated 25-February-2020. For investors heading into the FY 2025-26 trading day, understanding the collateral, leverage and square-off rules matters more than any single Nifty level, because a failed margin call can force a sale at the worst possible price.

This pre-open note unpacks the rulebook in four parts: the current MTF landscape, what changed when the 2020 pledge regime kicked in, what to watch in your funded book today, and a FAQ for the questions clients most often raise with their broker's risk desk. Every number cited here ties back to a SEBI circular or the briefing notes for this article, you will not find invented price levels or hypothetical return projections in the sections below.

Market Snapshot: where MTF sits in the cash market plumbing

MTF is a cash-segment product, not a derivative. Unlike futures, the underlying shares are delivered to the client's demat with a margin pledge tag in favour of the broker, and corporate action entitlements such as dividends flow to the client (handling of bonuses, rights and splits varies by broker contract). Only securities classified as Group I by the exchange are eligible for MTF funding. Group I is the most liquid bucket on the exchange, defined as stocks that either trade in the derivatives segment, or feature in the top 1,500 stocks by market capitalisation, subject to an average daily turnover threshold of at least Rs 10 lakh and a continuous rolling window check on impact cost and liquidity.

The table below summarises the core MTF rule set as it stands under the existing SEBI framework.

The 50% initial margin floor is the headline number. If a client buys Rs 2,00,000 of an eligible stock under MTF, the client must put up at least Rs 1,00,000 as initial margin and the broker funds the remaining Rs 1,00,000. The broker is free to ask for a higher margin where house policy or stock-specific risk warrants it, but cannot go below the SEBI floor. The funded amount carries interest at the broker's published rate, which for most retail brokers sits in the 12-24% annualised range disclosed in their schedule of charges, accrued daily and debited to the client ledger.

What Moved Yesterday: the 2020 pledge overhaul that still drives MTF risk

The single most important change to MTF mechanics in recent years did not happen yesterday in the price tape, it happened in the pledge plumbing. Until February 2020, brokers ran power-of-attorney based pool account models for client securities. SEBI's 25-February-2020 circular replaced that with a margin pledge system, where every security used as collateral, including MTF funded shares, must sit in the client's own demat with a separate pledge tag in favour of the broker or clearing member. The client confirms the pledge via OTP, and the lien is visible in the client's holding statement.

Three practical consequences flow from that 2020 overhaul for anyone running a funded book this morning:

• The shares are never out of the client's demat. A broker default does not vaporise the holding, the pledgee tag is a lien, not a transfer.
• Every pledge and unpledge needs an active confirmation. If the OTP is missed, the margin is not recognised and the position becomes margin-deficient by the next day's risk file.
• Corporate actions on pledged stock continue to accrue to the client, but bonus or rights credits may temporarily land as unpledged free balance, leaving the funded book technically under-collateralised until the broker re-pledges. Check the broker's standard operating procedure on this before any corporate action date.

The square-off mechanic is the other piece of yesterday's rule set that still bites today. When mark-to-market losses push the available margin below the maintenance threshold, the broker issues a margin call. SEBI permits up to 5 trading days for the client to top up the margin in cash or additional eligible securities. If the call is not cured within that window, the broker is entitled to sell the pledged securities in the open market to recover dues. The proceeds first settle the funded amount and interest, with any residue credited to the client. In a fast-falling market the sale itself can move the price against the client, which is why the 5-day clock is the most watched timer on any MTF book.

What to Watch Today: pre-open checklist for funded positions

For a client carrying an MTF book into today's session, the open is less about the index and more about three quick checks. Run them before the first trade prints.

1. Group I eligibility on every holding. Exchanges refresh the Group I list periodically. A security that drops out of Group I ceases to be MTF-eligible on the effective date, and the broker may demand that the funded portion be converted to a fully-paid position (client pays the funded balance) or be squared off. Check the holding statement against the latest exchange circular.
2. Available margin against today's risk file. The end-of-day mark-to-market plus the broker's intraday volatility margin add-on determines whether the position is in a margin call this morning. If a call is open, the 5 trading day clock under the SEBI circular is already ticking.
3. Interest accrual on the funded leg. Funded amounts carry interest daily at the broker's MTF rate. A holding held for several months can see interest cost eat materially into any capital gain, the compounding cost is one reason MTF is typically a tactical, not a buy-and-hold, instrument.

The second table maps the daily MTF lifecycle to who acts and what document governs it.

For investors building the underlying systematic plan that an MTF position should sit on top of, the calculator suite on Oquilia is the right starting point. The SIP calculator helps quantify the base portfolio that funded trades are layered onto, the lumpsum calculator projects a one-time deployment against a target horizon, and the step-up SIP calculator models annual contribution increases. Recent Oquilia coverage on related market plumbing is also worth a read before the bell: the analysis on SEBI mid and small cap mutual fund stress tests explains the redemption-days disclosures fund houses publish, and the explainer on the ITR filing deadline of 31-July-2026 for non-audit cases covers the late-fee mechanics that hit any equity gains booked in the financial year.

The practical takeaway for the trading day

MTF is a regulator-built leverage facility, not a grey-market arrangement, and the rule set is unambiguous: Group I stocks only, 50% minimum initial margin, continuous maintenance margin, 5 trading days to cure a call, pledged collateral in the client's own demat. The discipline that separates a profitable MTF user from a serial square-off case is treating the funded amount as borrowed capital with a daily interest meter, and the margin call clock as a hard deadline, not a suggestion. Brokers publish their MTF interest rate and eligible-stock list on their websites under SEBI's disclosure norms, the client's job is to read both before the order, not after the call.

For the source documents, refer directly to SEBI's circulars page and search by circular number for CIR/MRD/DP/54/2017 (the 2017 MTF framework) and SEBI/HO/MIRSD/DOP/CIR/P/2020/28 (the 2020 margin pledge regime). These are the two documents that govern every funded equity position in the Indian cash market today.

FAQ

Which securities are eligible for MTF in the cash segment?

Only Group I securities, as classified by the stock exchange, can be funded under MTF. Group I includes stocks in the derivatives segment and stocks in the top 1,500 by market capitalisation that meet the average daily turnover threshold of at least Rs 10 lakh and the rolling liquidity checks, per SEBI Circular CIR/MRD/DP/54/2017.

What is the minimum initial margin a broker can charge for an MTF trade?

The SEBI floor is at least 50% of the trade value. A broker is free to demand a higher initial margin based on internal risk policy or stock-specific volatility, but cannot accept anything below the regulator's 50% threshold under SEBI Circular CIR/MRD/DP/54/2017.

How long does an investor have to meet a margin call before square-off?

The broker may issue a square-off instruction if the margin call is not cured within 5 trading days. Cure can be in additional cash or in further eligible securities pledged to the broker, in line with SEBI Circular CIR/MRD/DP/54/2017.

Are MTF-funded shares held by the broker or the client?

Under the SEBI Circular SEBI/HO/MIRSD/DOP/CIR/P/2020/28 dated 25-February-2020, the funded shares sit in the client's own demat account with a margin pledge tag in favour of the broker. The broker holds a lien, not ownership, and the client retains the underlying entitlement.

Who receives dividends on MTF-funded shares?

Dividends on MTF-funded stock accrue to the client, since the client is the beneficial owner under the margin pledge regime. Treatment of bonus issues, rights and stock splits varies by broker contract, the standard operating procedure is published in the MTF terms sheet that the client signs at account opening.

What interest do brokers charge on MTF funding?

Interest is at the broker's published MTF rate, which for retail brokers typically sits in the range of 12 percent to 24 percent per annum on the funded balance, accrued daily. The exact rate is set by the broker and disclosed in the schedule of charges, SEBI prescribes disclosure but does not cap the rate.

Can a broker square off MTF positions without notice?

The broker must follow the SEBI prescribed process of issuing a margin call and allowing the cure period before square-off. Where the cure period under SEBI Circular CIR/MRD/DP/54/2017 lapses without a top-up, the broker is entitled to sell the pledged securities to recover dues, with the residual proceeds credited to the client.
