(15)It may not be assumed that credit institutions will always receive liquidity support from other undertakings belonging to the same group or to the same institutional protection scheme when they experience difficulties in meeting their payment obligations. However, where no waiver has been granted for the application of the liquidity coverage ratio at individual level in accordance with Articles 8 or 10 of Regulation (EU) No 575/2013, liquidity flows between two credit institutions belonging to the same group or to the same institutional protection scheme should in principle receive symmetrical inflow and outflow rates to avoid the loss of liquidity in the internal market, provided that all the necessary safeguards are in place and only with the prior approval of the competent authorities involved. Such preferential treatment should only be given to cross-border flows on the basis of additional objective criteria, including the low liquidity risk profile of the provider and the receiver.
