The European Central Bank (ECB) President Mario Draghi said at a press conference on Wednesday that there are signs that quantitative easing by the central bank has been effective. He added that the economy in the Eurozone "has gained further momentum since the end of 2014".

Draghi pointed out the need to complete the full asset-buying programme. "The full implementation of all our monetary policy measures will provide the necessary support to the euro area recovery and bring inflation rates towards levels below, but close to, 2% in the medium term," the ECB president said.

Draghi dismissed concerns that the central bank will not find enough bonds to purchase.

The ECB president noted that there is no evidence for asset bubbles.
