Exam ICWIM Topic 1 Question 43 Discussion

A central counterparty reduces counterparty credit risk by becoming the buyer to every seller and the seller to every buyer. This process, often described as novation, means each trading participant faces the CCP rather than facing the original counterparty directly. By interposing itself between counterparties, the CCP centralises and manages default risk through mechanisms such as margining, default funds, netting of exposures, and robust risk controls. This structure lowers the risk that the failure of one market participant will cascade through the system, because the CCP's risk management framework is designed to absorb shocks and ensure trades can still be settled. Delivery versus payment is an important settlement risk control, but it is not the defining CCP feature in this question because DvP can exist without a CCP. Electronic book entry and dematerialisation relate to how securities are recorded and transferred, not to the core credit risk reduction mechanism of central clearing. The key risk reduction feature is that the CCP stands in the middle of the trade, replacing bilateral exposures with a centrally managed exposure.
