Multilateral netting
The clearing corporation's method of collapsing every trade a clearing member did in a settlement into one net figure per security and one net funds figure, so each member either pays in or receives a pay-out.
In plain language
On a busy day a broker buys and sells the same share many times, with many different counterparties. Settling each of those trades one by one would mean thousands of separate deliveries and payments.
Multilateral netting avoids that. The clearing corporation adds up everything a clearing member bought and sold in a security across all counterparties, and only the difference moves. If the member bought more than it sold, it receives shares; if it sold more than it bought, it delivers them. Money is treated the same way: every buy value and sell value is set off into one net amount to pay or to receive.
"Multilateral" is the key word. The netting is not between two brokers (that would be bilateral); it is across everyone, with the clearing corporation in the middle as the common counterparty.
How it works
The workbook describes clearing as "the process of determination of obligations, after which the obligations are discharged by settlement", and says a multilateral netting procedure is adopted to determine the net settlement obligations (delivery/receipt positions) of the clearing members. Each clearing member then has either a pay-in or a pay-out obligation for funds and for securities, separately.
In the T+1 cash market the sequence is:
- On T day the exchange sends all trade details to the clearing corporation.
- Custodians confirm institutional trades by 7:30 a.m. on T+1.
- The clearing corporation performs multilateral netting and downloads final obligations to members by 9:00 a.m. on T+1.
- Pay-in of funds and securities happens on T+1 (up to about 11:00 a.m.).
Netting has limits. For certain transactions or securities settlement is on a gross (trade-for-trade) basis, with no netting at all. Institutional investors are grossed at custodian level and must meet obligations gross, although custodians still settle net with the exchange. There is no netting between the T+1 and optional T+0 settlement cycles. Inside the broker, client positions are netted per client, never across clients.
A worked example
This is the workbook's own illustration. Three brokers trade security ABC on day T:
| Trade | Buyer | Seller | Qty | Price (Rs) | Value (Rs) |
|---|---|---|---|---|---|
| 1 | X | Y | 200 | 10.00 | 2,000 |
| 2 | Y | Z | 50 | 10.50 | 525 |
| 3 | X | Z | 100 | 10.50 | 1,050 |
| 4 | Y | X | 300 | 11.00 | 3,300 |
Net each broker:
- X bought 300 (200 + 100) and sold 300. Net shares 0. Funds: -2,000 - 1,050 + 3,300 = +Rs 250 to receive.
- Y bought 350 (50 + 300) and sold 200. Net 150 shares to receive. Funds: +2,000 - 525 - 3,300 = Rs 1,825 to pay.
- Z sold 150 (50 + 100) and bought nothing. Net 150 shares to deliver. Funds: +525 + 1,050 = Rs 1,575 to receive.
Check: shares delivered (150) equal shares received (150); funds paid (Rs 1,825) equal funds received (Rs 250 + Rs 1,575). Four trades with a gross value of Rs 6,875 and 650 shares settle as one delivery of 150 shares and Rs 1,825 of payments.
Why NISM asks about it
Chapter 5 (Clearing Process, sections 5.4, 5.6 and 5.6.6) is where multilateral netting is taught and illustrated, and the chapter's sample questions ask directly: "Which procedure is adopted to determine the net settlement obligations (delivery/receipt positions) of the clearing members?" The answer is multilateral netting, with novation, auto netting and pay-in as distractors. Chapter 6 (Settlement Process, section 6.2) then contrasts netted obligations with trade-to-trade (gross) obligations. Expect a numerical question built on a three-broker table like the one above.
Common exam traps
- Netting is not novation. Netting decides how much each member owes; novation decides who the counterparty is. The two appear together as options in the same question.
- Funds and securities are netted separately. A member can be a net receiver of shares and a net payer of money at the same time, as broker Y is above.
- Client positions are netted per client, not across clients. A broker cannot set one client's sale against another client's purchase to reduce a client's obligation.
- Gross (trade-for-trade) settlement has no netting. Pay-in equals cumulative sells and pay-out equals cumulative buys.
- No netting across T+1 and T+0. The two cycles settle separately even for the same member and security.
