The acquis in the area of economic and monetary policy contains specific rules requiring the independence of central banks in Member States, prohibiting direct financing of the public sector by the central banks and prohibiting privileged access of the public sector to financial institutions. Member States are expected to co-ordinate their economic policies and are subject to the Stability and Growth Pact on fiscal surveillance. New Member States are also committed to complying with the criteria laid down in the Treaty in order to be able to adopt the euro in due course after accession. Until then, they will participate in the Economic and Monetary Union as a Member State with a derogation from the use of the euro and shall treat their exchange rates as a matter of common concern.
