Maastricht - Article 104
Les banques centrales implémentent la politique monétaire au moyen de différents éléments, comme :
- la fixation des taux directeurs ; la fixation des niveaux de réserves obligatoires (RO) ;
- les opérations d'open market ;
- les interventions sur le marché des changes.
A central bank, reserve bank, or monetary authority is a banking institution granted the exclusive privilege to lend a government its currency.
Like a normal commercial bank, a central bank charges interest on the loans made to borrowers, primarily the government of whichever country the bank exists for, and to other commercial banks, typically as a 'lender of last resort'.
However, a central bank is distinguished from a normal commercial bank because it has a monopoly on creating the currency of that nation, which is loaned to the government in the form of legal tender. It is a bank that can lend money to other banks in times of need.
Its primary function is to provide the nation's money supply, but more active duties include controlling subsidized-loan interest rates, and acting as a lender of last resort to the banking sector during times of financial crisis (private banks often being integral to the national financial system).
It may also have supervisory powers, to ensure that banks and other financial institutions do not behave recklessly or fraudulently.
Most richer countries today have an "independent" central bank, that is, one which operates under rules designed to prevent political interference.
Some central banks are publicly owned, and others are privately owned. For example, the United States Federal Reserve is a quasi-public corporation.
