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.
ISDA has subsequently updated UST and repo clearing model comparison chart to reflect new information as of March 22, 2026.
PLEASE NOTE: You may need to download the comparison matrices and save them as PDFs to your respective devices in order to be able to “zoom in” to the relevant comparison matrix to a level that is readable. We recommend viewing the matrices using adobe which allows for higher resolution when zooming in.
