Under the ESCB’s Statute, the monetary income of all participating national central banks will be paid into a common pool and then redistributed in accordance with the key for capital subscription. This procedure was chosen because it is impossible to predict the regional distribution of central bank money creation within the monetary union.
Incidentally, this is not a problem, as the entire euro area will be a single currency area with identical money market rates and uniformly applicable terms governing the allocation of central bank money. However, to ensure an equitable distribution of income from the creation of money within the ESCB, a profit distribution mechanism will be installed.
