The Bundesbank is responsible for the ongoing supervision of credit institutions in Germany. Through their on-site inspections, the Bundesbank's supervisors gain a deep insight into institutions' capital and liquidity adequacy.

A well functioning economy requires a stable banking system. Banking supervision is therefore responsible for monitoring credit institutions’ business activity and maintaining investor confidence. In Germany, the task of financial supervision is shared by the Bundesbank and the Federal Financial Supervisory Authority (BaFin). In particular, the Bundesbank is in charge of monitoring the credit institutions.

The Deutsche Bundesbank does not conduct transactions (purchase, vending, etc.) in foreign currencies (banknotes and coins) and precious metals with the general public (including credit institutions).

The branches of the Bundesbank supply the economy with euro banknotes and coins, and offers private customers the opportunity to exchange D-Mark banknotes and coins free-of-charge and with no fixed deadline.
