Clearing & T+1 Settlement

Say Maya placed her order before the market opened on Thursday 1 October 2026: 2 HUL shares at up to ₹1875.00. Before the lunch prep, her app shows one green word.

The match fixed more than the price: it fixed two duties. Maya's side must pay ₹3740.20: show the note on Maya's 2 HUL at the open for the 2 shares (2 × ₹1870.10, plus a few rupees of charges, which Brokerage Charges counts), and the seller's side must deliver them. She pays the opening auction's one price, not her ₹1875.00 limit, as Market Timings & Auctions shows. Neither side can back out: a matched trade cannot be cancelled the way an order still waiting in the book can (Placing Your First Order).

What has not happened is the swap. Settlement is the step in which the money goes to the seller's side and the shares to the buyer's demat account, each only against the other; markets call it delivery versus payment: show the note on Delivery versus payment. Until then the shares stay on the seller's side: if the seller is an individual like Maya, they sit in the seller's own demat account, blocked for this sale. Her vegetable order fits only so far. She knows her supplier and pays when the crates come; on the exchange she never learns who sold, and her money was set aside on Thursday, though it reaches the seller only on Monday. So who makes sure a stranger delivers? Chapter 4 answers that.

Each fact has its own record. The trade is on the contract note, the broker's official record of it, due within 24 hours (Brokerage Charges reads one); the money is on her broker's ledger; the shares are on the record of the depository, the company that keeps the electronic register of who owns which shares (CDSL, for Maya; The Three Accounts). An app can show the shares early, often marked "T1" until they settle; the depository's record is the one that counts.

T is the trade date, the day the trade is matched. T+1 is one working day later. A working day here is one on which the exchange, the banks and the clearing corporation all work: NSE leaves out bank holidays, exchange holidays, Saturdays and Sundays when it counts. The settlement date is the day that count lands on. Companies use it too: to be on the list for a dividend, a buyer's shares must have settled by the company's record date (Corporate Actions).

Maya's count. Thursday 1 October is T. Friday 2 October was Gandhi Jayanti: show the note on Gandhi Jayanti, a holiday for trading and for settlement, and Saturday and Sunday followed. So T+1 is Monday 5 October. NSE Clearing, the company that settles NSE's trades, publishes this a month ahead: its October 2026 calendar, issued on 3 September, lists settlement 2026186: show the note on Settlement number with trade date 1 October and settlement date 5 October. The same number is printed on her contract note.

In an ordinary week it is simply the next day: a trade on Thursday 8 October settled on Friday 9 October (settlement 2026190). A Friday trade waits for the weekend: Friday 9 October settled on Monday 12 October.

Two calendars, not one. NSE publishes two holiday lists each year, one for trading and one for clearing (settlement), and they differ. In 2026 four weekdays traded without settling: 19 February, 19 March, 1 April (the banks' year-end closing) and 26 August. So trades of Tuesday 25 August and Wednesday 26 August both settled on Thursday 27 August, one batch after the other; the second was paid out at 9:00 pm.

Why only one day. India finished moving every share to T+1 on 27 January 2023, after about twenty years on T+2. The United States followed on 28 May 2024, sixteen months later; the European Union, the United Kingdom and Switzerland plan 11 October 2027. A shorter wait means less time for prices to move while promises are open, and money tied up for less time: SEBI's stated aims for a shorter cycle are cost and time efficiency, clearer charges for investors and stronger risk management at clearing corporations.

Who does what, in one line: NSE matched the trade; NSE Clearing, the clearing corporation, settles it; CDSL keeps Maya's shares; a clearing bank moves the money; Sahi, her broker, is her link to all of them.

Thursday 1 October, trade day. Sahi set aside enough of the money she had moved from her HDFC Bank account to cover the order as she placed it (The Three Accounts): brokers must collect margin, money set aside against a trade, before an order goes in (chapter 4 says why). Her available balance at Sahi dropped on Thursday, but no money has left for the seller yet: pay-in is on Monday. On the other side, the seller's 2 shares wait, blocked, in the seller's demat (chapter 1). That evening, by 9:00 pm, NSE Clearing sends each clearing member: show the note on Clearing member (the firm that settles for a broker) its provisional figures.

Monday 5 October, by 9:00 am: final obligations, what each clearing member must pay or deliver. By 10:30 am, pay-in: Sahi's clearing member pays in its one net sum of money for the day from its account at one of NSE Clearing's 14 clearing banks, and Maya's ₹3740.20 travels inside that sum (chapter 4 explains the netting). The seller's 2 shares move from the seller's demat to NSE Clearing.

From 1:30 pm, money out: NSE Clearing pays the seller's clearing member, which passes the money to the seller's broker and on to the seller. By 3:30 pm, shares out: NSE Clearing pays the 2 HUL straight into Maya's CDSL demat account. Until 25 February 2025 bought shares went to the broker's account first, and the broker passed them on.

The rule under it: nobody is paid out until pay-in is complete.

The mirror, when Maya sells. Say she sells the 2 shares on Thursday 8 October at that day's close, ₹1844.50. On Thursday her shares are blocked in her own demat; she approves with a code from her depository, or Sahi uses a DDPI: show the note on DDPI, the standing permission she may have signed for her broker to deliver shares she sells (The Three Accounts). On Friday 9 October they leave at pay-in, and from 1:30 pm NSE Clearing pays Sahi's side ₹3689.00 for them (2 × ₹1844.50); Sahi credits her that, less charges. She can withdraw it to her HDFC Bank account; the same lesson explains when money left with a broker comes back.

For Maya's trade that company is NSE Clearing: NSE's own clearing corporation, formerly NSCCL, clearing since April 1996. BSE (formerly the Bombay Stock Exchange) has BSE Clearing, formerly ICCL. SEBI regulates both. Since 2019 a broker may clear all its trades through the clearing corporation of its choice, whichever exchange they were made on; the steps are the same, and the contract note names the one used.

One deal becomes two. The moment Maya's order meets a seller's, NSE Clearing steps into the middle: Maya's side now deals only with NSE Clearing, and so does the seller's. This step is called novation: show the note on Novation. In law NSE Clearing faces the clearing members, and Maya faces her broker, Sahi. So she never needs to know or trust the seller.

Money moves as one net sum. By evening NSE Clearing adds up every trade each clearing member made, and each member pays in or receives one net sum of money for the day; this is netting. Say Sahi's clients bought 1000 HUL and sold 900 that Thursday (an illustration): Sahi's clearing member pays in only the money for the difference, 100 shares. Shares are treated differently. They are netted only within one client: a client who bought and sold the same share that day delivers or receives only the difference (chapter 6). Across a broker's clients they are not netted: since direct pay-out went live on 25 February 2025, every client's sale is delivered in full and every client's purchase goes to that client's own demat. So in the illustration Sahi's sellers deliver all 900 shares, and its buyers receive all 1000 in their own demat accounts. Shares on the trade-for-trade list, where the exchange makes every trade settle on its own, are not netted at all (Circuit Limits & Surveillance explains the list).

Money first. NSE Clearing takes margin, money set aside against a bad day's move, from each clearing member at the moment of the trade, and gives it back once that member has paid in. The broker, in turn, collects it from the client before the order goes in. That is why Sahi set Maya's money aside on Thursday, four days before pay-in: if a buyer's side failed to pay on Monday, money to cover the loss would already be in hand. (Margin, Leverage & Pledging covers margin in full.)

What stands behind the promise. If a broker's side cannot pay or deliver, its own margin and money go first; then a slice of NSE Clearing's own money; then the Core Settlement Guarantee Fund, the fund's official name: ₹581.45 crore: show the note on Core SGF, share market for the share market, part of ₹13549.26 crore (about $1.4 billion) across all NSE Clearing's markets in September 2026. The side that did its part is paid either way: a seller still gets the money if the buyer's broker fails, and a buyer still gets shares or cash if the seller's fails (chapter 5).

What it does not cover. It stands behind settlement between clearing members. It does not insure against a fall in the price, or against your own broker misusing your money or shares. That risk has its own rules: since the 2025 change in chapter 3, bought shares land in your own demat, not your broker's, and Stay Safe covers the rest.

Has this ever been tested? On Monday 15 September 2008 the US investment bank Lehman Brothers filed for bankruptcy. In London the clearing house LCH.Clearnet was holding more than 66000 of its interest-rate contracts, with a face value of about $9 trillion. It dealt with every one of them, and its other members lost nothing. The contracts were not shares, but the rule is the one in the figure: the failing firm's own money is used first.

A short delivery is shares owed at pay-in that do not arrive. Suppose the seller's side delivers neither of Maya's 2 HUL at 10:30 am on Monday 5 October (a what-if; no such shortage is known for this trade).

At once, NSE Clearing charges the seller's broker for the missing shares at their settlement price: show the note on Settlement price, a price NSE Clearing sets for every share each trading day, here Thursday's, the last trading day before pay-in: ₹1837.99 in NSE's and BSE's daily price files, so 2 × ₹1837.99 = ₹3675.98. The money is held while the shares are found.

Road A, the auction. That afternoon NSE Clearing holds a buy-in auction, an auction to buy the missing shares, on NSE's trading system. It settles the next working day: Maya receives her 2 HUL on Tuesday 6 October (T+2), one day late, and pays nothing more. If the auction price is above the price the shares were charged at, the seller's side pays the difference.

Road B, the close-out. If nobody sells in the auction, the deal is closed out: settled in cash at the higher of two prices. The first is the highest price on the exchanges from the trade day to the auction day: ₹1874.95, BSE's high on 1 October (NSE's was ₹1873.60). The second is 20% above the auction day's price, taken as NSE Clearing's settlement price for 5 October, ₹1838.42: 1838.42 × 1.20 = ₹2206.10: show the note on HUL's close-out price, what-if. That second price is the higher, so it is the one used. Maya paid ₹3740.20 for shares she did not get; she would receive about ₹4412 instead (2 × ₹2206.10), the close-out money going to the side that was let down. The seller's side pays it: about ₹672 more than the ₹3740.20 it was selling for, before charges.

Two exceptions go straight to a close-out, with no auction: shares on the trade-for-trade list, and T+0 trades (chapters 6 and 7). A shortage between two clients of the same broker goes to the same auction.

What it means. For the buyer, a short delivery changes when the shares come, or turns them into cash; it does not cost her more. For a seller who did not have the shares, it can cost a fifth of the price, or more.

Each sale settles one working day after it is made, on its own date. Take three days on which Maya could sell her 2 HUL.

The same day, Thursday 1 October. If Maya bought 2 and sold 2 that Thursday, the clearing corporation nets them (chapter 4): no shares move, only the price difference, less charges. That is an intraday trade (Trading vs Investing; its costs are in Brokerage Charges).

Monday 5 October, before 3:30 pm. Her shares are due by 3:30 pm that day. A sale now settles on Tuesday 6 October, and its 2 shares must be in by Tuesday's pay-in. Brokers call this "buy today, sell tomorrow" (BTST: show the note on BTST); it is a nickname, not an exchange rule. The chain: if Thursday's seller fails to deliver to Maya, her shares come through Monday's auction on Tuesday, or as cash, and Maya can then fail to deliver to her own buyer. Chapter 5's rules apply to her, as the seller: the auction difference, or a close-out at a fifth or more above that day's price.

Thursday 8 October, or any day after Monday. The shares are in her demat; she sells from what she holds, and this risk is gone. That sale settles on Friday 9 October.

Trade-for-trade shares. Here every trade settles on its own, with no netting: even a buy and a sale on the same day must each be settled in full, so a sale of shares you do not yet hold falls short, and a shortage is closed out directly in cash, with no auction, at a price at least 20% above the settlement price. How to Read a Stock Quote shows how a quote page marks these shares; Circuit Limits & Surveillance explains why a share is moved there.

Before selling shares you bought recently, ask three questions. Are they in my demat account, not only in my app? Is the share off the trade-for-trade: show the note on Trade-for-trade list? Do I know my broker's rule for selling before credit, and what it does if my purchase arrives short?

What it is. On NSE, HUL trades under two labels, called series: its regular one, EQ, whose trades settle on T+1, and a second, T0, whose trades settle the same day. On 30 October 2026 NSE's quote data listed both, so HUL was in India's optional same-day cycle. T0 is a second cycle running beside T+1, never in place of it. It began as a trial on 28 March 2024 with 25 shares and a few brokers. From 31 January 2025 it was widened, 100 companies a month, to the 500 largest by market value as on 31 December 2024, and every broker may now offer it, and may charge a different brokerage for it.

How it runs. One session, 9:15 am to 1:30 pm. A seller's shares must be blocked by 1:45 pm; obligations are ready by 2:30 pm; shares and money move the same day. A shortage is closed out directly, with no auction. There is no T+0 trading on a settlement or bank holiday: NSE Clearing's October 2026 calendar has a T+0 settlement for every working day, from 2026682 on Thursday 1 October, and none for 2 October.

Its own price. T+0 trades happen within 1%: show the note on T+0 price band of the same share's T+1 price (the band moves after each 0.5% move), do not set the closing price or move the index, and are not netted against T+1 trades. On 30 October 2026, at about 1:00 pm, HUL's T0 band ran from ₹1839.50 to ₹1876.50.

What it is for. Having the shares, or the sale money, on the same day. You choose it on the order, if your broker offers it (Placing Your First Order); if you do nothing, your trade settles on T+1, as every trade in this lesson did. With the shares in her account, the page she opens next is a quote, and the next lesson reads it number by number.
