The Deutsche Bundesbank is the Federal Republic of Germany's independent central bank. It has been a member of the Eurosystem since 1999, sharing responsibility for the single currency, the euro, with the other national central banks and the European Central Bank.

The Bundesbank's primary business is Eurosystem monetary policy. Its primary responsibility is to ensure price stability in the eurozone. This necessitates in-depth analyses, a long-term perspective, and objectivity toward individual interests. Economic, fiscal, and wage policies all contribute to the Bundesbank's stability policy.
