Settlement, Clearing & Custody Basics
What happens after you click buy or sell, and which institutions ensure trades complete properly.
When you execute a trade, the transaction does not complete instantly in the background. A set of processes involving the exchange, a clearing corporation, and a depository work together to ensure that the buyer receives securities and the seller receives funds — reliably and securely.
Understanding settlement gives you realistic expectations about when your funds and shares actually move and protects you from assumptions that could lead to operational errors.
Key Concepts
Settlement cycle defines how long it takes after a trade for final transfer of shares and funds to occur. India moved to T+1 settlement for equities in 2023, meaning shares and funds settle the next business day after the trade date. This is faster than the previous T+2 cycle.
Clearing is the process of calculating net obligations — who owes what to whom — across all trades that occurred during a session. The National Securities Clearing Corporation (NSCCL) and BSE Clearing Corporation perform this function in India.
Novation is a key risk-management mechanism. When a trade is executed, the clearing corporation steps in as the central counterparty — becoming the buyer to every seller and the seller to every buyer. This eliminates counterparty risk. You do not need to worry whether the specific person on the other side of your trade can fulfill their obligation.
Custodians are institutions (primarily banks) that hold securities on behalf of large institutional investors. For retail investors, the demat account with the depository serves the same function — your broker is not holding your shares; the depository is.
Failed trades occur when one party cannot deliver securities or funds on the settlement date. Exchanges and clearing corporations have mechanisms — including auctions and penalty processes — to handle such failures without disrupting other participants.
Common Mistakes
Assuming shares purchased today will be available to sell immediately under the delivery (CNC) segment can cause order failures. Under T+1 settlement, shares settle the next day.
Confusing the broker holding funds with the depository holding securities. Your broker holds your funds (in a segregated client account) but your securities are in your demat account with the depository, separate from the broker's own assets.
Key Takeaways
India follows T+1 settlement for equities. Shares and funds move one business day after trade execution.
Clearing corporations act as central counterparties, eliminating bilateral counterparty risk for all market participants.
Your securities are held by the depository (NSDL/CDSL) via your demat account, not by your broker directly.
Settlement failure mechanisms protect you from the impact of other participants defaulting on their obligations.
