(9)In relation to accounts in TARGET, the calculation of maximum holding amounts should generally give appropriate consideration to settlement obligations arising from an NB-PSP’s direct participation in ancillary payment systems that settle in TARGET, and the maximum holding amount limit should generally also apply to an NB-PSP’s holdings on the TARGET technical accounts of such ancillary systems. However, the scarcity of reliable data on the balances held by an NB-PSP on TARGET accounts for the purposes of specific ancillary system procedures would hamper the effective daily monitoring that Eurosystem central banks should conduct to identify misuse by NB-PSPs of such accounts by the holding of excess liquidity. Specifically, Eurosystem central banks do not have visibility on the balances held by NB-PSPs on: (a) TARGET accounts for the purposes of the real-time gross settlement ancillary system settlement procedure D (hereinafter the ‘RTGS AS settlement procedure D’) referred to in Annex I, Part VI, Article 6, to Guideline (EU) 2022/912 (ECB/2022/8); and (b) TARGET accounts for the purposes of TARGET instant payment settlement (TIPS) ancillary system (TIPS AS) settlement procedures referred to in Annex I, Part VII, to that Guideline. Therefore, for present purposes, any funds held by an NB-PSP in TARGET accounts for the purposes of the RTGS AS settlement procedure D or TIPS AS settlement procedures should not be included in the calculation of a maximum holding amount limit, and no such limit should apply to those funds. Instead, a monthly self-attestation reporting regime should be instituted for NB-PSPs where relevant, to enable the relevant Eurosystem central banks to monitor whether funds held by NB-PSPs on TARGET accounts for such purposes are, in fact, being used to meet settlement obligations. Such a self-attestation reporting regime should include reports, on a monthly basis, of the peak and average daily overnight holdings of an NB-PSP on such accounts, as well as the NB-PSP’s peak and average daily settlement obligation amounts processed in the corresponding ancillary system.
