A clearing house is a financial intermediary that sits between buyers and sellers in a market to guarantee the successful exchange of assets and funds.
Understanding clearing houses
When Elephants execute a transaction on an exchange, the clearing house becomes the buyer to every seller and the seller to every buyer. This process, known as novation, transfers the counterparty credit risk from the individual market participants to the clearing house. By taking on this position, the clearing house ensures that if one party defaults, the other party still receives their owed assets or cash.
Clearing houses operate across global financial markets, handling assets such as equities and derivatives. To manage the risk of default, they require participants to post margin. Margin is collateral, usually in the form of cash or highly liquid securities, held to cover potential losses from market fluctuations. The amount of margin required changes daily based on market volatility and the specific positions held by the traders.
Another mechanism used by clearing houses is netting. Instead of processing every individual trade separately, the clearing house aggregates the daily transactions of a member firm to calculate a single net amount owed or due. Netting reduces the total volume of money and assets that must change hands, lowering transaction costs and operational risk for market participants.
Central counterparty clearing houses operate under strict regulatory frameworks in their respective jurisdictions around the world. Following the 2008 global financial crisis, international regulatory bodies mandated the clearing of standardized over-the-counter derivatives through these institutions to reduce systemic risk.
Example
Imagine two Elephants trading peanut futures on an international commodities exchange. Elephant A agrees to buy 10 tons of peanuts from Elephant B at a set price, with delivery scheduled for three months in the future. Once the trade is executed, the exchange clearing house takes over the contract. The clearing house becomes the buyer to Elephant B and the seller to Elephant A. Elephant A and Elephant B both deposit margin with the clearing house to guarantee their positions. If the price of peanuts drops sharply over the next month and Elephant A decides to default on the contract, Elephant B does not lose out on the trade. The clearing house absorbs the loss using the margin deposit of Elephant A and ensures Elephant B receives the agreed payment when the contract expires.
