Bundesbank President Jens Weidmann has drawn attention to the dangers of an even longer period of negative interest rates. "Holding interest rates lower for even longer would aggravate the risks and side effects of a very expensionary monetary policy", he said at this year‘s European Banking Congress in Frankfurt.

Bundesbank Executive Board member Joachim Wuermeling sees digital financial and money functions pursued by initiatives ranging from clouds to Libra as a major challenge facing European banking supervisors. At an event in Frankfurt, Wuermeling stated that “if risk-relevant links in the financial value chain evade supervision, for credit institutions, it’s a matter of a level playing field, but for us as supervisors it’s a question of financial stability.”
