In an interview to be published in Monday's edition of the Tagesspiegel newspaper, Weidmann said, "As the stability anchor for the common currency, Germany carries a special responsibility."
The Bundesbank head welcomed the fact that the state significantly reduced its deficit last year, but said this was no time to ease off from such efforts.
Weidmann sees a particular problem in Germany's looming first instalment for the permanent euro bailout fund, the European Stability Mechanism (ESM), which has not only been raised, but brought forward to this year.
Finance Minister Wolfgang Schäuble is faced with the tricky decision of either financing the contribution – thought to be higher than €4.3 billion – by taking on new debts or by imposing bigger federal budget cuts.
Unlike the temporary European Financial Stability Facility (EFSF) currently in place, the ESM will have to be backed with its own capital.
But Weidmann also remained optimistic for 2012, since Germany's economic situation was "relatively favourable." For that reason, the top banker warned against "talking" the country into a credit crunch, pointing out the European Central Bank (ECB) would provide the banks with enough liquidity.
Weidmann also insisted that the Bundesbank would not be playing a more active role in the euro crisis by buying up state bonds from troubled countries.
