Greece was also unavoidable at the conference, as the indebted country is in the process of drawing up an agreement with its creditors.
Draghi said there was a general will to reach an agreement with Greece, as he refused to comment on the current state of Greece's negotiations with its euro zone lenders.
"There must be a strong financial agreement that addresses the remaining sources of instability in the financial sector," he said.
On Tuesday, the European Commission, European Central Bank (ECB) and International Monetary Fund (IMF) drafted the broad lines of an agreement to put to the Greek government, according to Reuters, in a bid to resolve months of tense negotiations over Greek reforms and debt.
A Greek government official told CNBC Wednesday that the Athens government hadn't yet seen the proposals, however.
Any offer of a deal from creditors puts the ball firmly in Greece's court, although the consequences of it rejecting an agreement could be dire.
