Italian banks are selling off their domestic sovereign debt at unprecedented rates, leading to concerns that they will be hit hard when the European Central Bank ceases quantitative easing.
Italian banks reduced their holdings of sovereign debt by €12.6 billion ($21.5b) in December, and by €40b in the final three months of 2017, equivalent to 10.5 per cent of stock, according to analysis by investment advisory firm Jeffries.
Marchel Alexandrovich of Jeffries said: "This move in recent months is unprecedented, and in sharp contrast to what's taken place in Portugal."
The latest sell-off comes as the EU's third largest economy prepares to head to the polls in a close-run general election on March 4.
There are also fears that the robust growth in manufacturing seen in the recent months could weaken as the euro gains strength, dampening the appetite for Italian exports which have driven economic growth.
