It has used the euro as its currency since 1 January 1999, owing to a special agreement with the European Union (council decision 1999/98).

Issuance of euro-denominated coins is strictly limited by treaty, though somewhat more than usual is allowed in a year in which there is a change in the papacy.

Vatican City depends on Italy for practical production of banknotes, stamps and other valuable titles.
