Derivatives Market in India and SEBI Regulation

Updated 11 October 2026 · Fact-checked

India's derivatives market trades standardised futures and options on exchanges such as NSE and BSE. Contracts have fixed lot sizes and expiry dates, are cleared by a clearing corporation that guarantees trades, and are margined daily. SEBI regulates the market. Solve questions by identifying the rule, the body responsible, and the investor's risk.

Understand Derivatives Market in India and Regulation

A derivative is a contract whose value comes from an underlying asset such as a share, an index or a currency. In India, the exchange-traded derivatives you need to know are futures and options on indices and stocks. They trade on recognised stock exchanges like NSE and BSE.

Exchange-traded contracts are standardised. The exchange fixes the underlying, the lot size (the minimum quantity per contract), the expiry date and the strike prices for options. You cannot change these terms. This is different from an over-the-counter (OTC) contract, where two parties negotiate terms privately. Lot sizes and expiry cycles are set by the exchanges within the framework laid down by SEBI, and they are revised from time to time. So never memorise a lot size as a fixed number. Learn the principle.

Trades are cleared by a clearing corporation. It becomes the counterparty to every trade. This is called novation. The buyer and the seller each face the clearing corporation, not each other. This removes counterparty risk between traders. To protect itself, the clearing corporation collects margins from members, who collect them from clients. Common margins are initial margin and mark-to-market (MTM) margin. Futures positions are marked to market every day, so gains and losses are settled in cash daily. Index derivatives remain cash-settled. SEBI mandated physical settlement of stock derivatives in phases from 2018-19, starting with a select list of stocks. The details are revised over time, so learn the principle: index derivatives are cash-settled and stock derivatives are moving to physical settlement under SEBI's framework. Option buyers pay a premium upfront and have limited loss. Option sellers (writers) receive the premium, must post margin and can face large losses.

SEBI is the regulator. It approves the contract framework, eligibility criteria for stocks and indices, risk management norms and the rules for intermediaries. Exchanges and clearing corporations frame their own rules and bye-laws within this framework. Brokers and members who deal in derivatives must be registered with SEBI and the exchange.

For an investment adviser, the key point is suitability. Derivatives are leveraged. A small margin controls a large exposure, so losses can exceed the margin paid. They suit clients who understand the risk and have a clear purpose such as hedging. They are unsuitable for clients with low risk tolerance or little knowledge. Derivatives are risky and many retail traders lose money, which is why advisers must be careful before recommending them.

Key formulas to remember

Novation: Buyer ↔ Clearing Corporation ↔ Seller; The clearing corporation becomes the counterparty to both sides, which removes bilateral counterparty risk and guarantees settlement.
Contract value: Contract value = Price × Lot size; Use this to find exposure. Example: a lot of 50 units at ₹100 gives ₹5,000 exposure.
Profit or loss on a long futures position: (Exit price − Entry price) × Lot size × Number of lots; For a short position, reverse the sign: (Entry price − Exit price) × Lot size × Lots.
Daily MTM settlement: MTM = (Today's settlement price − Previous settlement price) × Quantity; A positive MTM on a long position is credited. A negative amount is debited in cash.
Option buyer's maximum loss: Maximum loss = Premium per unit × Lot size × Number of lots (equals the total premium paid); The premium is quoted per unit of the underlying, so multiply it by the lot size and the number of lots. The option seller's loss can be much larger. The buyer's loss is capped at the total premium paid.
Settlement type: Index derivatives: cash-settled; stock derivatives: physical settlement mandated by SEBI in phases from 2018-19, starting with a select list of stocks; Index derivatives remain cash-settled. The details of stock derivative settlement are revised over time, so use the settlement type stated in the question if it gives one.

How to solve Derivatives Market in India and Regulation questions

Use the same sequence for rule-based and numerical questions on this topic.

1Read the question and mark what is asked: a rule, a body, a risk or a calculation.
2Identify the contract type: futures or option, index or stock, buyer or seller.
3Recall who is responsible: SEBI (framework), exchange (contract terms), clearing corporation (guarantee and margin), or member (client dealing).
4For calculations, find the lot size and number of lots, then apply Price difference × Lot size × Lots.
5Check the direction: long gains when prices rise, short gains when prices fall. Option buyer's loss is capped at premium.
6Eliminate options that say the client faces no risk, that terms can be negotiated, or that the exchange itself is the counterparty.
7For adviser questions, choose the answer that puts suitability and client risk profile first.

Quickest way: Who, what, risk in 20 seconds

When to use it: Use it for one-mark conceptual questions where time is short.

Ask who: SEBI, exchange, clearing corporation or member.
Ask what: framework, contract terms, guarantee, margin or client dealing.
Ask the risk: leverage, unlimited loss for sellers, limited loss for buyers.
Pick the option that matches, and drop absolute words such as always or never unless the rule is truly absolute.

Common mistakes in Derivatives Market in India and Regulation

Saying the exchange guarantees settlement of trades.
Students link trading with the exchange and forget the clearing corporation.
Fix: Remember that the clearing corporation guarantees settlement through novation. The exchange provides the trading platform.
Thinking an option buyer can lose more than the premium.
Students confuse buyers with sellers or with futures holders.
Fix: The buyer's loss is capped at the premium paid. An option seller's and a futures holder's potential losses are not limited to a premium and can exceed the margin deposited.
Treating futures like cash-market delivery trades with no daily settlement.
Students ignore mark-to-market.
Fix: Futures gains and losses are settled daily in cash, so margin top-ups can be called at any time.
Memorising a lot size or expiry day as fixed forever.
Old notes quote specific numbers that were later revised.
Fix: Learn that exchanges set lot sizes and expiry within the SEBI framework and revise them. Use the figures given in the question.
Recommending derivatives for speculation to any client who asks.
Students focus on returns and forget suitability.
Fix: Check risk profile, knowledge, financial capacity and purpose. Hedging with a clear need is easier to justify than speculation.

Worked examples

Example 1

An investor buys 2 lots of an index futures contract at 22,000. The lot size is 50. The index settles at 22,150 at expiry. What is the profit, ignoring costs?

Show the solution

Position is long, so profit = (Exit − Entry) × Lot size × Lots.
Price difference = 22,150 − 22,000 = 150.
Quantity = 50 × 2 = 100.
Profit = 150 × 100 = ₹15,000.

Answer: ₹15,000 profit

Example 2

Which statement about clearing in exchange-traded derivatives is correct? (a) The buyer and seller settle directly with each other. (b) The clearing corporation becomes the counterparty to both sides through novation. (c) SEBI guarantees every trade. (d) Clearing corporations only clear OTC contracts.

Show the solution

Recall that exchange-traded trades are cleared through a clearing corporation.
Novation means the clearing corporation steps in between buyer and seller.
Option (a) describes a bilateral OTC trade, so it is wrong.
SEBI is the regulator and does not guarantee trades, so (c) is wrong.
Clearing corporations clear exchange-traded contracts, so (d) is wrong.

Answer: (b) The clearing corporation becomes the counterparty to both sides through novation.

Exam tips

Know the role split: SEBI frames rules, exchanges set contract terms, clearing corporations guarantee and collect margins.
Expect questions on suitability. The safest answer ties derivatives to risk profile, knowledge and purpose.
In calculations, always multiply by lot size and number of lots, and check long versus short.
Be careful with words such as only, always and guaranteed. Wrong options often use them.
With 25% negative marking, skip a question only if you cannot narrow it to two options.

Derivatives Market in India and Regulation: frequently asked questions

Who regulates the derivatives market in India?

SEBI regulates it. The exchanges and clearing corporations frame rules and bye-laws within the SEBI framework. Members and brokers must be registered.

What is a lot size in F&O?

It is the fixed minimum quantity of the underlying in one contract. The exchange sets it within SEBI's framework and may revise it. You trade in multiples of one lot.

What does the clearing corporation do?

It acts as the counterparty to every trade through novation, guarantees settlement and collects margins. This reduces the risk that one party defaults on another.

Are derivatives suitable for every retail investor?

No. They are leveraged and losses can exceed the margin paid. An adviser must check the client's risk profile, knowledge and purpose before suggesting them.
