The Eurosystem is the monetary authority of the eurozone, the collective of European Union member states that have adopted the euro as their sole official currency. The European Central Bank (ECB) has, under Article 16 of its Statute, the exclusive right to authorise the issuance of euro banknotes. Member states can issue euro coins, but the amount must be authorised by the ECB beforehand.
The Eurosystem consists of the ECB and the national central banks (NCB) of the 20 member states that are part of the eurozone. The national central banks apply the monetary policy of the ECB. The primary objective of the Eurosystem is price stability. Secondary objectives are financial stability and financial integration. The mission statement of the Eurosystem says that the ECB and the national central banks jointly contribute to achieving the objectives.
