A central counterparty (CCP), or clearing house, interposes itself in every trade it accepts: by novation the contract between buyer and seller is replaced by two contracts, one between the buyer and the CCP and one between the CCP and the seller. Each member then has a single counterparty, whatever the number of firms it traded with.
