With the European Central Bank (ECB) expected to launch a bond-buying program on Thursday, high-profile Italian business leaders have warned that it could involve risks and might not be enough to save the European "dream" from collapsing.
Although markets and business leaders are expecting the ECB to announce a quantitative easing (QE) program tomorrow, the size and scale of such a program is unknown. There is speculation that there could be a risk-sharing factor added to any QE program, with national central banks also expected to share some of the strain of buying government bonds with the ECB.
Carlo Messina, Intesa's chief executive, told CNBC Wednesday that risk-sharing was "not a good idea" but that some kind of stimulus program was needed in order for the euro zone to recover.
"The real point is about sharing risk," he said.
"If they decide not to share the risk that will be very good news for markets and the amount (of any QE package the ECB announces) could be around 500 - 600 billion euros ($578 billion) but the amount is not important,"
"It is very important that we come out of this crisis and that we recover in the whole of Europe, otherwise every country will pay the price of a lack of recovery," he added.
