Default rules

EURO1 is designed to ensure completion of settlement in the case of a default by any number of participants, based on the Liquidity Pool and Loss Sharing arrangements.

Exclusion, suspension and withdrawal from the EURO1 System

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

It can also decide voluntarily to leave the system.

Certain events may occur, including financial or operational defaults. Such defaults are addressed in first instance through the activation of incident handling and, as applicable, crisis management arrangements.

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 rules governing the system. The system’s rules are proprietary and confidential, and are available to all participants, to prospective participants that have applied to become a participant, and to relevant authorities including in particular the European Central Bank as the lead overseer of EURO1.

Temporary suspension

Failure to comply with the operational and legal criteria for participation and failure to pay or replenish when due settlement related obligations constitute suspension events.

Where relevant, an inquiry notice is sent to the participant to confirm the occurrence of a suspension event.

Participants must remedy the cause of a suspension event. An appeals procedure is in place in case the System Operator denies to terminate a suspension.


Events that may give rise to exclusion comprise in particular: 

  1. confirmed insolvency events 
  2. loss of authorisation to conduct banking business 
  3. unremedied suspension 

Consequences of suspension/exclusion

Subject to the specific provisions of the EURO1 System Documentation, in the event of suspension or exclusion, no payment messages will be processed in relation to a suspended or excluded participant as from the moment of its suspension or exclusion (and, in the case of suspension, as long as the suspension continues).

Withdrawal from the system

A participant in EURO1 may voluntarily withdraw from the system upon at least 30 days’ notice.
