On February 1, 2024, ISDA published a comparison of available US Treasury (UST) clearing models, as well as models for clearing repos at other central counterparties (CCPs) globally and models for clearing derivatives. This comparison is intended to help market participants understand existing and potential new clearing models for UST cash and repo transactions as they implement the US SEC’s recent rules requiring clearing of such transactions.

Since that time, ISDA updated the comparison to reflect new, and recent changes to existing, clearing models offered by the Fixed Income Clearing Corporation (FICC). This year, ISDA also added new clearing models that have been proposed by CME Securities Clearing (CMESC).

ISDA intends to continue to update this comparison matrix as new clearing models across the industry are proposed and finalized.

ISDA has subsequently updated UST and repo clearing model comparison chart to reflect new information as of March 22, 2026.
