(66)Where all other options are unavailable or demonstrably insufficient to safeguard financial stability, government participation in the shape of equity support or temporary public ownership should be possible, in accordance with applicable rules on State aid, including a restructuring of the operations of the CCP. In order to avoid moral hazard, such extraordinary public financial support should be provided only as a last resort, be temporary in nature and always be recovered over an appropriate period. Therefore, while not constituting an obstacle to applying government stabilisation tools, comprehensive and credible arrangements for the recoupment of funds should be established by Member States. The application of government stabilisation tools is without prejudice to the role of any central bank in potentially providing liquidity to the financial system, at the central bank’s exclusive discretion, even in times of stress.
