ISDA has submitted a response to the International Organization of Securities Commissions (IOSCO) consultation on post-trade risk reduction (PTRR) services.  PTRR services optimize bilateral and cleared derivatives portfolios to minimize the build-up of notional amounts and trade count, counterparty risk, and basis risk respectively, which in turn reduces systemic risk.  ISDA is broadly supportive of IOSCO’s proposed sound practices.
