Post-crisis regulatory reforms have reshaped and increased the amount of clearing activity in the OTC derivatives market. An emerging issue is so-called “client porting” – i.e. how central counterparties (CCPs) can transfer positions from one clearing member (CM) to another in the aftermath of one member defaulting. In this post, we discuss possible ways to offer clients temporary access to clearing services following a CM default, which we believe could increase the likelihood of successfully porting clients and avoiding further pressure on prices and market stability.
