Article 41U.K.
Host Member States shall, pending further coordination, retain responsibility in cooperation with the competent authorities of the home Member State for the supervision of the liquidity of the branches of credit institutions.
Without prejudice to the measures necessary for the reinforcement of the European Monetary System, host Member States shall retain complete responsibility for the measures resulting from the implementation of their monetary policies.
Such measures may not provide for discriminatory or restrictive treatment based on the fact that a credit institution is authorised in another Member State.
