The continued strengthening of the euro "would require further monetary policy accommodation," ECB President Mario Draghi has said. "That's an important dimension for our price stability."
Draghi's comments came at a meeting of the IMF and after the euro has increased 6% over the past year to $1.3885.
Draghi said that the euro's strength has been an important factor in causing eurozone inflation to drop to 0.5% on year.
CPI is even negative in some parts of the bloc, sparking increasing concerns about deflation and prompting the ECB to discuss unconventional policy such as quantitative easing.
Meanwhile, German Finance Minister Wolfgang Schaeuble and Bundesbank President Jens Weidmann have tried to talk markets out of being overly excited that the eurozone crisis is over. "It's good that markets have become more confident again," said Schaeuble. "But I've said that in parts they're already exaggerating again."
