Derivatives Market Structure and Regulation in India for PMS Distributors

Updated 11 October 2026 · Fact-checked

Derivatives in India trade on SEBI-regulated exchanges, with a clearing corporation guaranteeing every trade. Contracts have standard specifications and are marked to market daily. Portfolio managers may use derivatives only within SEBI rules and their disclosed approach, mainly for hedging and portfolio balancing, not for unbounded speculation.

Understand Derivatives Market Structure and Regulation in India

A derivative is a contract whose value comes from an underlying asset such as a stock, an index, a currency or a commodity. In India, the standardised ones are exchange-traded derivatives. They are futures and options traded on recognised stock exchanges such as NSE and BSE.

SEBI is the regulator of securities derivatives. Exchanges set the contract specifications: the underlying, the lot size (market lot), the expiry date, the tick size, the strike prices for options and the settlement method. You cannot change these terms. This standardisation is what makes the contracts liquid and tradable.

A clearing corporation sits between buyer and seller after the trade. It becomes the buyer to every seller and the seller to every buyer. This is called novation, and it removes counterparty risk. To protect itself, it collects margins from members and clients, and it marks positions to market every day. Gains and losses are settled in cash daily. Clearing members handle this on behalf of trading members and clients.

Exchanges and SEBI also control risk through position limits. These cap how large a position a member, client or entity can hold, so that no single player can distort the market. Stock derivatives are allowed only on stocks that meet eligibility criteria set by SEBI and the exchanges.

A portfolio manager registered under the SEBI (Portfolio Managers) Regulations, 2020 may use derivatives for a client only as the agreement and disclosure document allow. The usual permitted purposes are hedging and portfolio rebalancing. The manager must act in the client's interest, disclose the risks, and keep the client's funds separate from its own. Check the exact current limits in your NISM workbook, because limits change.

Key formulas to remember

Notional value of a futures position
Notional value = Price × Lot size × Number of lots
Margin is a percentage of this value, not of the premium.
Option premium outlay (buyer)
Premium paid = Premium per unit × Lot size × Number of lots
An option buyer's maximum loss is this premium. A seller's loss is not capped.
Daily mark-to-market (long futures)
MTM gain or loss = (Today's settlement price − Previous settlement price) × Lot size × Lots
For a short position, reverse the sign.
Role of clearing corporation
Buyer ↔ Clearing corporation ↔ Seller (novation)
Each party's contract is with the clearing corporation, not with the counterparty.
Regulatory rule for PMS use
Derivatives use must be within the PMS agreement, disclosure document and SEBI rules
Use for hedging and rebalancing is the safe answer in the exam.

How to solve Derivatives Market Structure and Regulation in India questions

Most questions test who does what, what is standardised and what is allowed. Use this order.

  1. 1Identify what the question is about: exchange, clearing corporation, regulator, contract term or PMS rule.
  2. 2Recall the role of each body. SEBI regulates, the exchange lists and trades, the clearing corporation guarantees and settles.
  3. 3If numbers are given, compute notional value, premium outlay or MTM using lot size.
  4. 4Check the direction: long gains when price rises, short gains when price falls.
  5. 5For PMS questions, ask whether the use is permitted by the agreement, disclosure document and SEBI rules, and whether it serves the client.
  6. 6Remove absolute options such as always, never or unlimited unless the rule is truly absolute.
  7. 7Pick the option that matches the rule in the workbook.

Quickest way: Role-matching shortcut

When to use it: Use it for theory MCQs on market structure, clearing and PMS rules when time is short.

  1. Match the word in the question to the body: guarantee or novation means clearing corporation; rules or limits mean SEBI or the exchange.
  2. Match the word to the feature: standard terms means exchange-traded; customised means OTC.
  3. For PMS, choose hedging, rebalancing and disclosure-based answers over speculation-based ones.
  4. For maths, multiply price change by lot size and lots, then fix the sign.

Common mistakes in Derivatives Market Structure and Regulation in India

  • Saying the counterparty is directly responsible for settlement.

    Students think of a trade as buyer versus seller.

    Fix: Remember novation. The clearing corporation becomes the counterparty to both sides.

  • Treating margin as the cost of the contract.

    Margin and premium are both upfront payments.

    Fix: Margin is a security deposit against futures or sold options. Premium is the price an option buyer pays.

  • Forgetting to multiply by lot size.

    Prices are quoted per unit.

    Fix: Always compute per-unit change first and then multiply by lot size and number of lots.

  • Assuming a PMS can use derivatives freely.

    Derivatives are seen as normal securities.

    Fix: Use must be within the client agreement, disclosure document and SEBI rules, and in the client's interest.

  • Mixing up exchange-traded and OTC features.

    Both are called derivatives.

    Fix: Exchange-traded means standardised and cleared by a clearing corporation. OTC means customised and bilateral.

Worked examples

Example 1

A portfolio manager buys 3 lots of a stock futures contract at ₹500. The lot size is 400 shares. The settlement price the next day is ₹510. What is the day's mark-to-market amount?

Show the solution
  1. Price change = ₹510 − ₹500 = ₹10 per share.
  2. Total quantity = 400 × 3 = 1,200 shares.
  3. MTM = ₹10 × 1,200 = ₹12,000.
  4. The position is long and price rose, so it is a gain.

Answer: Gain of ₹12,000, settled in cash through the clearing corporation.

Example 2

Which statement best describes the role of the clearing corporation in exchange-traded derivatives?

Show the solution
  1. The options in such a question usually mix up roles of the regulator, exchange and clearing corporation.
  2. Novation means it becomes buyer to every seller and seller to every buyer.
  3. This removes the counterparty risk between the original buyer and seller.
  4. It also collects margins and settles daily gains and losses.

Answer: It acts as the counterparty to both sides of every trade, guarantees settlement and manages risk through margins.

Exam tips

  • Know the role of SEBI, exchange and clearing corporation separately. Questions often swap them.
  • Read lot size carefully in numerical questions. It is the most common trap.
  • For PMS questions, the safe answer is hedging and rebalancing within the disclosed approach.
  • Verify numerical limits against your latest NISM workbook. Do not rely on old figures.
  • XXI-A has negative marking of 10% of the marks for a question, so skip only if you cannot eliminate any option.

Derivatives Market Structure and Regulation in India: frequently asked questions

Can a PMS invest in derivatives under SEBI rules?

Yes, if the portfolio management agreement and disclosure document allow it and it is within SEBI limits. It is typically used for hedging and rebalancing. The manager must act in the client's interest.

Who guarantees settlement of exchange-traded derivatives in India?

The clearing corporation. It becomes the counterparty to both buyer and seller through novation. It uses margins and daily mark-to-market to manage risk.

What is the difference between margin and premium?

Premium is the price an option buyer pays to the seller. Margin is a deposit collected from those with obligations, such as futures traders and option sellers, to cover potential losses.

Why do position limits exist?

They stop any single participant from holding a position large enough to distort the market or create systemic risk. SEBI and the exchanges set them.
