Danmarks Nationalbank undertakes all functions related to the management of the Danish central-government debt. The division of responsibility is set out in an agreement between the Ministry of Finance of Denmark and Danmarks Nationalbank.
Danish banknotes are printed at Danmarks Nationalbank's Banknote Printing Works.
The bank was established on 1 August 1818 by King Frederick VI of Denmark. The private bank was given a 90-year monopoly on currency issue, which was extended in 1907 out to 1938. In 1914, the National Bank became the sole banker for the Danish government. The bank became fully independent of the government in 1936.
The official logo of the bank is a nineteenth-century version of Denmark's coat of arms showing the insignia of Denmark, Schleswig, and Holstein. The two latter provinces were lost in the 1864 Second War of Schleswig, and the bank is the only official Danish institution still using this insignia. Since the late 19th century, coins minted by the bank carry a heart-shaped mint mark. Before this time, the Mint used a mark showing the royal crown.
