"De Nederlandsche Bank (DNB)" is the central bank of the Netherlands and also acts as a supervisor of the financial sector. Founded in 1848, DNB is now wholly owned by the Dutch State and responsible for monitoring financial stability in the Netherlands. Its main tasks include ensuring low inflation, payment traffic, and supervising the soundness and integrity of financial institutions.

Since the credit crisis, supervision by DNB has been significantly tightened. In addition to DNB, the Authority for the Financial Markets (AFM) is the other financial regulator in the Netherlands, with the AFM being responsible for conduct supervision and DNB for prudential supervision.

With the arrival of the Economic and Monetary Union (EMU) in 1999, the European Central Bank (ECB) took over the policy tasks of national central banks, including DNB. DNB now implements the ECB's policy, but the president of DNB still has a say in the ECB's decision-making.
