DTCC is undertaking a multi-year effort to transform its systems into a more advanced, modular platform. The modernized DTC Settlement Web system will support lightweight messaging through ISO 20022 format only, through distributed messaging (MQ IPT) and file (sFTP) channels. Settlement reports (data output) will also be harmonized with updated formats.
