Other settlement systems, such as those for retail payments and high-value payments as well as securities and foreign exchange settlement, are currently also connected to TARGET2 via the ancillary system interface. Six standardised settlement procedures, known as ancillary system interface (ASI) procedures, are used to settle the transactions from these ancillary systems via the accounts of the participants in TARGET2, and thus in central bank money. The concept of settlement on T2 accounts will also be maintained in the wake of the TARGET2/T2S consolidation. In total, the RTGS settlement service offers five dedicated settlement procedures – A to E – which are tailored to the specific needs of the individual ancillary systems. Unlike the current situation for TARGET2, looking ahead, all five settlement procedures will be available for the settlement of ancillary system transactions from 19:30 onwards. The following document provides an overview of the planned use of the settlement procedures and the envisaged settlement times of the individual ancillary systems.
