The Bank of Italy calculates the monthly general government debt on the basis of statistical rules established at European level (“Maastricht debt”).
The debt aggregate is calculated according to the definition adopted in the Excessive Deficit Procedure of the European Union (Council Regulation (EC) No. 479/2009), as the sum of General government financial liabilities in the following categories: currency and deposits, debt securities, and loans; liabilities are valued at face value. Debt is alto consolidated, thus excluding liabilities of which the corresponding financial assets are held by the sector of general government.
The list of institutional units included in General government is updated and published every year by Istat.
