Central counterparty
Also written CCP · Central counterparty (CCP) · Central counter-party · Central counterparty clearing · Central Counterparty (CCP)
The clearing corporation that interposes itself in every exchange trade, becoming buyer to every seller and seller to every buyer, so neither side carries the other's credit risk.
In plain language
On an exchange you never learn who took the other side of your trade, and you never need to. The moment the trade is matched, the clearing corporation steps into the middle of it: it becomes the buyer to the seller and the seller to the buyer, and the original pair stop being counterparties to each other.
The legal mechanism that does this is novation — the clearing corporation substituting itself as the legal counterparty to both sides.
What the arrangement buys is specific and worth being precise about. It removes counterparty credit risk (the risk your counterparty fails before settlement) and settlement risk (the risk it fails on the day). It removes nothing else. Your position can still lose money; the CCP simply guarantees that if it makes money, you will be paid.
How it works
Because every trade faces the same entity, obligations across a member's trades can be netted down to a single figure in each security and in funds, which cuts the number of payments sharply.
The CCP then has to make sure it can honour the guarantee it has given. The workbook lists the machinery: capital adequacy and net worth requirements for members, upfront initial margin and extreme loss margin on every open position, SPAN-based VaR margining, daily and intra-day mark-to-market settled in cash on a T+1 basis, client-level collateral segregation, online real-time position and margin monitoring, alerts as collateral utilisation rises, a risk reduction mode, and automatic disablement from trading when limits are breached.
As Exchange Traded Interest Rate Derivatives sit within the currency derivatives segment, the same risk containment mechanism applies to them.
Who does this in India. For exchange-traded IRD, NSE Clearing Ltd (NCL) and Indian Clearing Corporation Ltd (ICCL). For OTC government securities and many OTC interest rate derivatives, the Clearing Corporation of India Ltd (CCIL), which guarantees settlement by novation with G-sec trades settling on DvP-III — securities and funds both netted — on a T+1 basis.
The formula
Before novation: Buyer ←──── contract ────→ Seller
(each carries the other's credit risk)
After novation: Buyer ←──→ Clearing Corporation ←──→ Seller
(each faces the CCP only)
A worked example
Take the workbook's hedge. Investor X sells 250 lots of the October GOI bond future at Rs 99.95 — Rs 5 crore of notional — through a trading member who clears through NCL.
The person on the other side is irrelevant to him from the moment the trade matches. NCL novates: NCL is the buyer of X's 250 lots, and NCL is the seller of 250 lots to whoever bought them.
On expiry the bond settles at Rs 98.36 and X is owed
(99.95 − 98.36) × 250 × 2,000 = Rs 7,95,000
Suppose the buyer defaults. X is still paid Rs 7,95,000 — not by the buyer, but by NCL, which drew initial margin and extreme loss margin from the buyer up front and marked the position to market daily, collecting the loss in cash on a T+1 basis every single day it accrued. The default is NCL's problem, met from that margin and, if it falls short, from the Core Settlement Guarantee Fund and the default waterfall behind it.
Netting, on the same day. If X's clearing member is simultaneously long 150 lots for another client, the member owes or is owed on a net 100 lots rather than settling 400 lots gross — one payment instead of two, and margin computed on the net exposure at member level with client collateral kept segregated.
Why NISM asks about it
Chapter 7 (Clearing, Settlement and Risk Management of IRD), section 7.2.1, defines the clearing corporation and lists what it does as a central counterparty. Chapter 2 uses the same idea to separate exchange-traded from OTC derivatives: the trade guarantee is the reason ETD has no counterparty credit risk and OTCD does. Chapter 1 covers CCIL's role in G-sec settlement.
Questions ask which entity is the legal counterparty to an exchange trade, what novation means under the SEBI (Stock Exchanges and Clearing Corporations) Regulations 2018, which clearing corporations serve ETIRD, and — the one most often missed — what risk the guarantee does not cover.
Common exam traps
- The exchange is not the CCP. The exchange brings buyer and seller together; the clearing corporation settles the trade and carries the guarantee. Two entities, two functions.
- Novation is the mechanism; central counterparty is the role. Questions phrase it either way and expect you to recognise both.
- The guarantee covers credit and settlement risk only. Market risk, liquidity risk, leverage risk and basis risk are all untouched — Chapter 10 lists them separately for exactly this reason.
- CCIL is not NCL or ICCL. CCIL is the CCP for OTC G-secs and OTC interest rate derivatives; NCL and ICCL clear exchange-traded IRD.
- A CCP concentrates risk as well as removing it. That is why the margin framework, the Core SGF and the default waterfall exist, and why a clearing corporation is a systemically important institution.
- MTM on futures is settled in cash on T+1; on options it is adjusted against liquid assets. The workbook draws that distinction explicitly.
Where this is taught
Free preparation for NISM Series V-DRelated terms
- NovationThe clearing corporation stepping into the middle of every trade — becoming the buyer to every seller and the seller to every buyer — so that neither side carries the other's default risk.
- Core Settlement Guarantee FundA fund maintained by the clearing corporation for each segment, used to fund a defaulting clearing member's obligations and complete settlement without disrupting the normal process.
- Extreme Loss MarginA flat 3.5 per cent margin collected on cash-market positions to cover losses falling outside what the VaR margin is designed to capture.
- Margin pledgeThe only permitted way for a client to give securities as margin — a special pledge created in the depository system that leaves the shares in the client's own demat account instead of transferring them to the broker.
- SPANThe scenario-based system clearing corporations use to compute initial margin — it revalues a client's whole derivatives portfolio under sixteen what-if scenarios and charges the worst loss.
- Clearing corporationThe entity that steps between every buyer and seller in the derivatives segment by novation, becoming the counterparty to both sides and guaranteeing that the trade settles.
- Mark to MarketThe daily settlement of a futures position at that day's closing price, so gains and losses are paid in cash every evening instead of accumulating until expiry.
- Systemic riskThe risk that one participant's default triggers defaults by others until the settlement system itself fails — the domino risk, not the market risk.
- Initial marginThe deposit both the buyer and the seller of a futures contract must place before the position is accepted, sized to cover a 99% worst-case one-day loss on that position.
