Trading, Clearing and Settlement Mechanism in the Indian Secondary Market

Updated 11 October 2026 · Fact-checked

Trading is the matching of buy and sell orders on the exchange's electronic screen. Clearing is the work of determining what each member owes or is owed, done by the clearing corporation. Settlement is the actual exchange of securities and funds. Indian equity uses rolling settlement, where each trade settles a fixed number of days after the trade day.

Understand Trading, Clearing and Settlement Mechanism

Every trade on a stock exchange passes through three stages: trading, clearing and settlement. You can remember them as match, compute, deliver. Mixing them up is the most common way students lose marks.

Trading happens on a screen-based, order-driven system. Brokers enter orders into the exchange's electronic platform. The system matches buy and sell orders by price and then by time. Buyers and sellers do not meet or know each other. The main order types are market orders (executed at the best available price), limit orders (executed only at the stated price or better), stop-loss orders (triggered when the price reaches a set level) and time-based orders such as day orders and immediate-or-cancel orders.

Clearing starts after the trade. The clearing corporation takes the trade details from the exchange and works out each clearing member's obligation. It nets the member's purchases against its sales in each security, so the member owes either securities or funds. In most cases the clearing corporation steps in as the central counterparty. It becomes the buyer to every seller and the seller to every buyer. This is called novation. A buyer therefore does not carry the risk that the seller defaults.

Settlement is the final step. Securities move through the depository from the seller's demat account to the buyer's, and funds move through the clearing banks. India uses rolling settlement, where each day's trades are settled a fixed number of business days later, instead of all trades in a week being settled together. The cycle for equity has been shortened over the years to T+2 and then T+1, where T is the trade day. SEBI decides the cycle, and you should check the current circular before the exam.

Risk management keeps the system safe if a member defaults. Tools include margins (initial and mark-to-market), exposure limits, price bands and circuit breakers, and a settlement guarantee fund kept by the clearing corporation. Under Section 9 of the SCRA, a recognised stock exchange can make bye-laws, with SEBI's previous approval, covering the clearing house, periodic settlement, margin requirements, the days for settlement, the consequences of default and the levy of fines and penalties. SEBI can also issue directions under Section 12A after an inquiry.

Key rules to remember

Three stages of a trade: Trading (order matching) → Clearing (obligation determination) → Settlement (delivery of securities and funds); Always define each stage separately and in this order.
Rolling settlement: Settlement date = Trade day (T) + fixed number of business days; Under T+1, a trade on Monday settles on Tuesday, if both are business days. Check the current SEBI circular for the cycle in force.
Net obligation of a member: Net obligation = Total buys − Total sells (in each security, and in funds); This is the netting that the clearing corporation does for each clearing member.
Novation: Clearing corporation = buyer to every seller + seller to every buyer; This removes counterparty risk between the original parties.
Bye-law power, SCRA Section 9(1): Recognised stock exchange + previous approval of SEBI → bye-laws for regulation and control of contracts; Section 9(2) lists the matters, including the clearing house, margins, settlement days and default consequences.
SEBI directions, SCRA Section 12A(1): Inquiry + satisfaction that it is necessary → SEBI may issue directions; The grounds are investor interest or orderly market development, preventing detrimental conduct of affairs, and securing proper management.

How to solve Trading, Clearing and Settlement Mechanism questions

Use this method for any question on how trades are executed, cleared and settled, or on the legal and risk framework around them.

1Read the question and mark whether it asks about trading, clearing, settlement, risk management or all of them.
2Define the key term in one or two lines, such as order types, rolling settlement or novation.
3Explain the process in order: order entry and matching, trade confirmation, netting by the clearing corporation, then pay-in and pay-out.
4Name the institution that performs each step: the exchange, the clearing corporation, the depository and the clearing banks.
5Add the risk management tools that apply: margins, limits, price bands, circuit breakers and the guarantee fund.
6Link to the law where relevant, such as the bye-law power in Section 9 of the SCRA or SEBI's directions power in Section 12A.
7Finish with a short conclusion that answers the exact question asked.

Quickest way: Match, Compute, Deliver, Protect

When to use it: Use it for short-note questions and for the first few lines of any long answer when time is limited.

Write the one-line meaning of the term asked.
Write the sequence: match (trading), compute (clearing), deliver (settlement), protect (risk management).
Give one fact for each: order types, netting and novation, T+ cycle, margins.
Add one legal anchor, such as Section 9 bye-laws, and close with a one-line conclusion.

Common mistakes in Trading, Clearing and Settlement Mechanism

Using clearing and settlement as the same thing.
Both happen after the trade and are often spoken of together as 'clearing and settlement'.
Fix: Say that clearing determines the obligations through netting, and settlement is the actual transfer of securities and funds.
Saying that the stock exchange itself settles the trades.
Students think of the exchange as the single body running the market.
Fix: Name the clearing corporation as the body that clears and guarantees the trades, and the depository and banks as the channels for delivery and payment.
Writing that T+1 means the next calendar day.
T+1 is read literally without the business-day rule.
Fix: Write that settlement falls on the next business day after the trade day. Weekends and exchange holidays are skipped.
Mixing up market orders and limit orders.
Both are placed with a broker, and the names sound alike.
Fix: A market order gives priority to speed and takes the best available price. A limit order gives priority to price and may not be executed.
Giving the cycle as a fixed rule of the Act.
Students memorise T+1 as if it were a permanent legal provision.
Fix: Say that the settlement cycle is set by SEBI and can change, and that the SCRA gives exchanges bye-law powers on settlement days under Section 9(2)(h).
Leaving out risk management in a long answer.
Students focus on the process steps and forget how defaults are handled.
Fix: Always add a short paragraph on margins, exposure limits, circuit breakers, and the settlement guarantee fund.

Worked examples

Example 1

Distinguish between clearing and settlement in the secondary market. (Short note)

Show the solution

Provision or meaning: Clearing is the process of determining the obligations of members arising from trades. Settlement is the discharge of those obligations.
Analysis of clearing: The clearing corporation takes the trade data, nets each member's purchases and sales in each security, and arrives at a net obligation of securities and funds. It usually acts as the central counterparty through novation.
Analysis of settlement: On the settlement day, the seller's securities are moved to the buyer's demat account through the depository, and funds are moved through clearing banks. This is called pay-in and pay-out.
Difference in one line: Clearing is computation and risk assumption, while settlement is the final delivery and payment.
Legal link: Under Section 9(2)(b) of the SCRA, a recognised stock exchange's bye-laws, with SEBI's approval, may provide for a clearing house for the periodical settlement of contracts and the delivery of and payment for securities.

Answer: Clearing determines what each member owes or is owed, through netting, with the clearing corporation guaranteeing performance. Settlement is the actual transfer of securities and funds on the settlement date. Clearing comes first and settlement follows.

Example 2

A broker buys 500 shares and sells 300 shares of the same company on the same day for the same settlement. Under T+1 rolling settlement, the trade day is Wednesday, with no holiday. State the broker's net position in the security and the settlement day.

Show the solution

Netting: Purchases are 500 shares and sales are 300 shares of the same security for the same settlement.
Net obligation = 500 − 300 = 200 shares.
The broker is a net buyer, so it will receive 200 shares and must pay the funds for the net value.
Settlement day: Under T+1, settlement is one business day after the trade day. Wednesday + 1 business day = Thursday.
Conclusion: The clearing corporation will settle the broker's net position on Thursday.

Answer: The broker's net position is a receipt of 200 shares, with funds payable on the net value. Settlement takes place on Thursday.

Exam tips

Write the sequence of trading, clearing and settlement in every answer on this topic, and keep the three terms separate.
Learn the order types in one line each, with the key feature: market for speed, limit for price, stop-loss for protection.
Quote Section 9 of the SCRA for bye-laws and Section 12A for SEBI directions only for the points they actually cover, and do not add other section numbers unless you are sure.
For the settlement cycle, say it is fixed by SEBI and mention T+1 as the current equity cycle, but check the latest circular before the exam.
Close long answers with a conclusion that links risk management to investor protection.

Trading, Clearing and Settlement Mechanism: frequently asked questions

What is the difference between clearing and settlement?

Clearing is the calculation of each member's net obligations in securities and funds after the trades. Settlement is the actual transfer of securities and money on the settlement date. The clearing corporation handles clearing, while the depository and banks support settlement.

What does T+1 rolling settlement mean?

T is the trade day, and T+1 means the trade settles one business day later. 'Rolling' means each day's trades have their own settlement date, instead of all trades being settled together at the end of a period. SEBI fixes the cycle, so confirm the current rule.

What is novation in clearing?

Novation means the clearing corporation becomes the counterparty to both sides of the trade. It acts as the buyer to the seller and the seller to the buyer. This protects each party from the default of the other.

Can a stock exchange make its own rules on settlement?

Yes, within limits. Under Section 9 of the SCRA, a recognised stock exchange may make bye-laws for the regulation and control of contracts, including the clearing house, settlement days and margins. These bye-laws need SEBI's previous approval.
