The European Central Bank
The European Central Bank has made its regular five-yearly change to its capital key, which decides the size of the shares in its capital held by the European Union’s national central banks.
The shares held by NCBs are calculated on the basis of eurozone member states’ proportions of the EU’s population and GDP “in equal measure”, the ECB said. The calculations also adjust the amount NCBs must contribute to the ECB’s capital.
The data for this calculation is provided by the European Commission
