Any hint that the country may be locked again in parliamentary inertia, as in the final months of Berlusconi’s last government, would push the markets to question the credibility of Italy’s fiscal-consolidation plan, jeopardizing the country’s ability to refinance its debt. That debt is the largest in the eurozone – at roughly €2 trillion ($2.6 trillion), or 120% of the country’s GDP – which means that Italy can be helped, but not rescued.
