Clearing & Settlement in India: T+1 Cycle Explained (2026)

Section 1: What Happens After You Click "Buy"

When you place a buy order on your broker's app, it feels instant. The stock shows up in your positions. But behind the scenes, a complex, multi-party process unfolds across the next 24 hours. Let us trace the complete journey of your order.

Imagine you buy 100 shares of Infosys at ₹1,500 on Monday at 10:30 AM. Here is what happens step by step:

1. Order Placement (10:30:00 AM): You place the order on Zerodha. The app sends it to Zerodha's order management system.
2. Order Routing (10:30:00.01 AM): Zerodha routes your order to NSE (or BSE). This takes milliseconds.
3. Order Matching (10:30:00.02 AM): NSE's matching engine finds a seller willing to sell at ₹1,500. Trade is executed. You get a "trade confirmation."
4. Trade Reporting: NSE reports the trade to both brokers (yours and the seller's) and to the clearing corporation (NSCCL).
5. Clearing (Monday evening): NSCCL calculates net obligations — how much money you owe, how many shares the seller owes.
6. Settlement (Tuesday - T+1): Your money (₹1,50,000) goes from your bank to the seller. The seller's 100 Infosys shares move from their demat to your demat.

Section 2: Clearing Corporations — The Guarantors

The most critical but invisible players in the settlement process are the clearing corporations. They stand between every buyer and seller, guaranteeing that both sides honor their obligations. This is called novation — the clearing corporation becomes the buyer to every seller and the seller to every buyer.

NSCCL (NSE Clearing Corporation Limited)

NSCCL handles all clearing and settlement for trades executed on NSE. It manages a Settlement Guarantee Fund (SGF) worth thousands of crores. Even if a broker defaults, NSCCL ensures your trade is honored. This is why you never have to worry about the counterparty — NSCCL has you covered.

ICCL (Indian Clearing Corporation Limited)

ICCL does the same job for BSE. It operates independently with its own settlement guarantee fund. Every BSE trade is cleared and settled through ICCL.

Section 3: CDSL vs NSDL — Where Your Shares Actually Live

Your shares do not sit inside your broker's system. They are held electronically at a depository — think of it as a digital bank for securities. India has two depositories:

NSDL (National Securities Depository Limited)

Founded in 1996, NSDL was India's first depository. It was promoted by NSE, IDBI Bank, and UTI. NSDL holds about 65-70% of India's total demat assets by value. Your demat account number starting withIN followed by 14 digits is an NSDL account.

CDSL (Central Depository Services Limited)

Founded in 1999, CDSL was promoted by BSE. It holds about 30-35% of assets by value but has more individual accounts (thanks to discount brokers like Zerodha choosing CDSL). Your demat account number with 16 digits starting with a number is a CDSL account. If you are on Zerodha, you are on CDSL.

Both depositories do the same job — hold your shares in electronic form, process transfers during settlement, and let you pledge shares for margin. The choice is made by your broker, not you. And it does not matter which one you are on — both are equally safe and regulated by SEBI.

Section 4: The Complete Money Flow

Let us trace exactly where your ₹1,50,000 goes when you buy 100 Infosys shares at ₹1,500:

Step 1: Money Leaves Your Bank

Your ₹1,50,000 is debited from your linked bank account (via UPI mandate or net banking). It goes to your broker's client funds account — a special bank account that brokers must maintain separately from their own business funds. SEBI mandates this segregation.

Step 2: Broker Pays the Clearing Corporation

Your broker (Zerodha) pays the net amount to NSCCL from the client funds account. This happens on T+1 morning. NSCCL uses these funds along with the seller's shares to complete settlement.

Step 3: Shares Move to Your Demat

Simultaneously, NSCCL instructs the depository (CDSL/NSDL) to transfer 100 Infosys shares from the seller's demat account to your demat account. By 1:30 PM on T+1, the shares are in your demat and the money is in the seller's bank.

Step 4: Settlement Complete

You now legally own 100 shares of Infosys. They are in your name in the depository. You can hold them forever, sell them, pledge them for margin, or transfer them to another broker.

Section 5: Why T+1 Settlement Changed Everything

Before January 2023, India used T+2 settlement. The move to T+1 had massive implications:

• Faster access to shares: You can sell shares you bought yesterday. Under T+2, you had to wait 2 days.
• Faster access to sale proceeds: Money from selling shares reaches your bank account the next day, not after 2 days.
• Reduced counterparty risk: Less time between trade and settlement means less risk of someone defaulting.
• Lower margin requirements: Brokers need to block less capital since settlement is faster.
• FII challenges: Foreign investors in different time zones found T+1 challenging due to pre-funding requirements and currency conversion timelines. This has been partially addressed with a special window.
