The bankers were speaking at a conference in Frankfurt as investors closely watch the European Central Bank for its reaction to accelerating inflation.
Deutsche Bank CEO Christian Sewing said inflation will “persist for longer” and Commerzbank CEO Manfred Knof said “we believe inflation is going to stay.”
Sewing also said a reaction from the ECB was needed earlier than ECB President Christine Lagarde had just suggested.
But BNP Paribas Chairman Jean Lemierre said slightly higher inflation “would not be bad” and that there should not be an “endless discussion” about inflation.
“The real question today is not inflation but growth,” he said.
