"De Nederlandsche Bank (DNB)" is the central bank of the Netherlands and also serves as the regulator of the financial sector. Established in 1848, today DNB is wholly owned by the Dutch state and responsible for monitoring financial stability in the Netherlands. Its main tasks include ensuring low inflation, the payment system, and monitoring the soundness and integrity of financial institutions.

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

With the advent of 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 ECB policy, but DNB's president still has a say in ECB decision-making.
