Settlement Cycles and Rolling Settlement (T+1) Explained

Understand Settlement Cycles and Rolling Settlement

Key formulas to remember

Rolling settlement date (equity cash)

Settlement day = T + 1 working day

T is the trading day. Count only working days, skipping weekends and exchange holidays.

Account period vs rolling

Account period: many days of trades, one settlement date. Rolling: each trading day has its own settlement date.

Rolling settlement has no carry-forward within a period.

Pay-in

Pay-in = sellers' members deliver securities and buyers' members pay funds to the clearing corporation

Members pay in to the clearing corporation, not directly to the other party in the trade.

Pay-out

Pay-out = clearing corporation gives securities to buyers' members and funds to sellers' members

Pay-out is made by the clearing corporation to members on a net basis, not by the counterparty.

Net obligation

Funds obligation = total buy value − total sell value, across all securities for the member (positive = pay, negative = receive). Securities obligation = quantity bought − quantity sold, calculated for each security separately.

Settlement is on a net basis for each member, not trade by trade. Funds are netted across all securities, while securities are netted security by security.

How to solve Settlement Cycles and Rolling Settlement questions

1. 1Identify the trading day T and the cycle given (T+1 for equity cash unless the question says otherwise).
2. 2Check whether the question asks about the trade date, pay-in date, pay-out date or the client's receipt.
3. 3Count working days only. Skip Saturdays, Sundays and any holiday mentioned.
4. 4If the question compares systems, decide whether it describes rolling settlement (each day separate) or account period (bunched, one date).
5. 5For pay-in and pay-out, ask who delivers and who receives: at pay-in, sellers' members deliver securities and buyers' members pay funds to the clearing corporation; at pay-out, the clearing corporation gives securities to buyers' members and funds to sellers' members.
6. 6Eliminate options that overstate, such as 'always the same calendar day' or 'includes holidays'.
7. 7Confirm the answer matches the trade-to-settlement logic before marking.

Quickest way: Count the working days, then match pay-in to pay-out

Common mistakes in Settlement Cycles and Rolling Settlement

• Counting Saturdays, Sundays or holidays as settlement days.

  Students count calendar days instead of working days.

  Fix: Always count only days when the exchange and banks are open for settlement.

• Confusing rolling settlement with account period settlement.

  Both settle trades after a delay, so they look alike.

  Fix: Remember: rolling gives each trade day its own settlement date; account period bunches trades into one date.

• Mixing up pay-in and pay-out.

  The words sound similar and the direction is relative to the clearing corporation.

  Fix: Pay-in is into the clearing corporation; pay-out is out of it.

• Assuming the client receives shares directly from the exchange at pay-out.

  Students ignore the broker and depository participant layers.

  Fix: The pay-out goes to the member first. The broker then credits the client's demat account.

• Believing the cycle is a law of nature and cannot change.

  Students memorise T+1 without knowing it is set by SEBI.

  Fix: Remember that SEBI prescribes the cycle. SEBI moved the cycle from T+5 to T+3, T+2 and then T+1, which was phased in from January 2022 and applied to all listed equity by January 2023.

• Treating settlement as trade by trade.

  The word 'trade' suggests individual settlement.

  Fix: Obligations are netted per member for each settlement, so a member settles the net position.
