Exclusion, Suspension and Withdrawal from the RT1 System

The occurrence of a suspension or exclusion event and the consequences thereof for the suspended / excluded participant and for the other participants are determined solely in accordance with the RT1 Rules. The systems’ rules are proprietary and confidential, and are available to all participants, to prospective participants that have applied for becoming a participant, and to relevant authorities including in particular the European Central Bank / Eurosystem as overseer of RT1.

Operational defaults will be addressed in first instance through the activation of incident handling and, as applicable, crisis management arrangements.

A participant can be prevented by the System Operator from continuing to participate in the system if certain events occur.


Events that may give rise to exclusion comprise in particular:

  1. termination of access to TARGET2 account
  2. loss of license to act as a credit institution
  3. insolvency or comparable situations (unless an exclusion or suspension would contravene legislation implementing the Bank Recovery and Resolution Directive (BRRD) or equivalent third country legislation)
  4. a suspension event has not been remedied within 30 calendar days


The criteria for participation in the RT1 System consist of necessary legal, technical and operational requirements to enable the processing of SCT Inst transactions, as well as funding and de-funding operations in TARGET2.

A participant may be suspended if non-compliance with the ongoing criteria for participation cannot be otherwise mitigated, e.g. in the case of relocation outside SEPA.


A participant can withdraw from the RT1 System by giving notice of termination at least five TARGET2 business days prior to the withdrawal.
