Central clearing, also known as central counterparty (CCP) clearing, is a process used in financial markets to reduce counterparty risk and increase the efficiency of trading and settlement.

In traditional financial transactions, when two parties enter into a trade (such as buying and selling a financial instrument), they become counterparties to each other. This means that if one party defaults on their obligations (e.g., fails to deliver the agreed-upon asset or make the payment), the other party is exposed to financial risk.

Central clearing addresses this risk by inserting a third party, known as a central counterparty (CCP), between the original counterparties. The CCP acts as a guarantor for both sides of the trade. When a trade is executed, it steps in as the buyer to the seller and the seller to the buyer. This means that each party’s exposure is now to the CCP, rather than directly to the original counterparty.

Key features of central clearing include:

Risk Mitigation: By becoming the counterparty to all trades, the CCP takes on the risk of default. This reduces the counterparty risk faced by individual market participants.

Netting: The CCP can net positions across multiple participants, which can significantly reduce the amount of capital required to support trading activity. For example, if an entity has both long and short positions, the CCP can offset them, reducing the overall capital requirement.

Margining: The CCP requires both sides of a trade to post collateral (margin) to cover potential losses. This ensures that even in the event of a default, the CCP has the resources to fulfill the trade.

Standardization: Central clearing often requires standardized contracts, which can improve market transparency and liquidity.
Regulation and Oversight: CCPs are usually highly regulated entities subject to strict oversight by financial authorities.

Interoperability: Some CCPs can clear trades across multiple trading platforms or exchanges, allowing for greater market efficiency and flexibility.

Default Waterfall: In the event of a default by a participant, a predefined series of steps is followed to cover the losses. Typically, the defaulting participant’s margin is first used, followed by a default fund contributed by all participants, and in extreme cases, the CCP’s own capital.

Central clearing is widely used in many financial markets, including equities, fixed income, and derivatives markets. It plays a crucial role in reducing systemic risk and ensuring the stability and integrity of financial markets; however, it is not infallible. Some believe that having a single central counterparty simply concentrates default risk in a single place and is potentially not as risk-reducing as has been portrayed.
