(11)In order to foster a culture of compliance with the requirements concerning maximum holding amount limits, the relevant Eurosystem central bank should impose a penalty on an NB-PSP that holds amounts in excess of the relevant maximum holding amount on such accounts. In order to deter repeated or systematic breaches, any incidents of breach involving significant amounts in excess of the relevant maximum holding amounts, or failures to reduce any such excess amounts held on the NB-PSP’s accounts promptly after receipt should be among the events deemed to be a material non-compliance with the applicable requirements. In such cases the relevant Eurosystem central bank should be permitted to terminate the participation of the NB-PSP in the relevant central bank operated payment system and to impose an additional penalty in relation to any account that is closed as a result.
