What is a central counterparty
A central counterparty (CCP), often called a clearing house, is an entity that stands between the buyer and the seller of an exchange trade and guarantees that each side receives what it was promised, even if the other side fails.
Formal definition: a CCP interposes itself between the counterparties to contracts traded on one or more markets. Through a legal process called novation, the original contract between buyer and seller is replaced by separate contracts, one between the buyer and the CCP and one between the CCP and the seller. The CCP becomes the buyer to every seller and the seller to every buyer.
In Pakistan, trades on the stock exchange are cleared and settled through NCCPL (National Clearing Company of Pakistan Limited), the CCP for that market. The wider supervisor is the Securities and Exchange Commission of Pakistan (SECP), with trading in listed securities and commodities only via SECP-licensed securities and futures brokers.

Worked example (hypothetical)
Ali places a buy order for shares on the exchange through his broker. Bina's broker sells the same shares. The orders match.
- Trade: Ali and Bina never deal with each other directly.
- Novation: the CCP becomes Bina's buyer and Ali's seller.
- Margin: both brokers have already posted collateral (margin) with the CCP. While the trade is open, the CCP marks positions to market and can call for more margin if prices move against a member.
- Settlement: on the settlement date, cash moves from Ali's side to the CCP and on to Bina's side, and shares move the other way. See clearing and settlement.
- If Bina's broker defaults: the CCP still delivers shares to Ali. It covers the gap using, in order, the defaulter's margin, the defaulter's contribution to the default fund, its own capital, and then other members' default fund contributions. This order is called the default waterfall.
Ali's risk shifts from "will Bina pay?" to "is the CCP sound?". That is the main purpose of a CCP.
Where you will see the term
- Broker contract notes and account statements: clearing fees, NCCPL charges or "cleared through" lines. See account statement.
- Futures and options platforms: initial margin and variation margin set by the clearing house.
- News: CCPs raising margin requirements in volatile markets, or regulators reviewing CCP risk.
Edge cases for experienced traders
- OTC products are often not centrally cleared. With a forex or CFD broker, the broker itself is usually your counterparty, not a CCP. See A-book and B-book. Leveraged CFD and forex trading can lose money fast, and no clearing house stands behind that kind of contract.
- Concentration risk: a CCP removes many bilateral risks but concentrates them in a single entity. A CCP failure would be a financial contagion event.
- Procyclical margin: sharp margin increases during a sell-off can force members to sell, which can add to the move.
- The guarantee covers performance, not price. A CCP makes sure the trade settles. It does not protect you from market losses or from a broker misusing client assets. Asset protection depends on segregation rules and the custodian.
- Offshore platforms: per the SECP, offshore platforms have no Pakistani licence or oversight and offer no legal protection or recourse. See regulation and safety.
