In the RTGS component of T2, communication with one RTGS DCA can be carried out via several BICs. This communication via so-called "multi-addressee BICs" is also possible today in the current TARGET2 system; the BICs are applied in the header of the FIN message (MT). In T2, you will find them in the Business Application Header (BAH). In addition, the relevant messages of the ISO 20022 standard require the specification of the "instructing agent" or the "instructed agent" at transaction level. According to the UDFS for RTGS, "Instructing Agent" and "Instructed Agent" must be filled with the BIC of the RTGS DCA on which the transaction should be carried out. Therefore, for messages from or to multi-addressee BICs, a BIC different from the business application header must be set in the "Instructing Agent" or "Instructed Agent".
Especially for one-leg-out payments, i.e. for payments originating from the correspondent banking area (based on the Usage Guidelines of CBPR+) to T2-RTGS or for payments originating from T2-RTGS to the correspondent banking area, market participants requested that the payments and the BICs that are to be used should be clarified by means of concrete example scenarios. These example scenarios, that show with which BICs the corresponding elements of a pacs.009 message (FinancialInstitutionCreditTransfer) should be filled, can be found in the following file.
