Development of the OTC transaction clearing system

KDPW_CCP is running a project aiming to offer new communication solutions to KDPW_CCP participants, including preparation for the implementation of state-of-the-art solutions giving participants access to dedicated system components via the website interface – the KDPW Group Service Portal and the exchange of FpML messages. According to preliminary assumptions, FpML messages will be used in kdpw_otc to report the status of transactions accepted for clearing, includingthe confirmation or rejection of clearing; the FpML standard is not expected to be used in the following processes: account management, participation management, fees, cash settlement, guarantee fund processing (the FpML standard provides communication solutions which support the exchange of data concerning collateral management; however, our analysis suggests that ISO 20022 offers messages which are a better match for KDPW_CCP requirements in this area). 

Process descriptions, structures and examples of all FpML and XML messages were provided to KDPW_CCP participants on March 31, 2022 (ref. letter CCP/ZW/242/2022). Structures of OTC clearing messages are scheduled to be modified in Q4 2022.
The request for the above mentioned material should be sent to

As of May 2022, new solutions are being tested in the TSTB test environment (except for auctions - testing as of July 1, 2022).
