Fragmenting clearing across multiple central counterparties (CCPs) is costly. This is because dealers providing liquidity globally, cannot net trades cleared in different CCPs and this increases their collateral costs. These costs are then passed on to their clients through price distortions...

Central counterparties (CCPs) are systemically important. When a clearing member defaults, the CCP sells the defaulted portfolio to surviving members in an auction, and losses, if any, are partly absorbed by a cash pool prefunded by the surviving members. We propose a tractable auction model...

Fragmenting clearing across multiple central counterparties (CCPs) is costly because globaldealers cannot net positions across CCPs. They have to collateralize both the short positionin one CCP and an offsetting long position in another CCP. This observation coupled with astructural net order...

We investigate empirically how the balance sheet characteristics of central counterparties (CCPs) affect their modelling of credit risk. CCPs set initial margin (IM), i.e., the collateral for transactions, to limit counterparty credit risk. When a CCP's IM model fails on a large scale, the CCP...
