LONDON (Reuters) - Italian bonds and stocks sold off sharply on Monday and safe haven German debt rallied on fears of possible fresh elections and as investors took advantage of an initial rally to sell Italian assets, analysts said.
Jitters over a potential snap election in Spain added to worries over Southern European markets.
Italian assets briefly gained in early trade after President Sergio Matarella rejected a eurosceptic candidate for economy minister.
But the relief rally proved short-lived, with investors concerned over the risk that a fresh election could deliver an even stronger mandate for Italy’s anti-establishment parties.
This pushed Italian bond yield spreads over peers to their highest levels in years, and Italian stocks dropped sharply in value.
“I suspect the market initially interpreted it as good news, but now they are considering what will happen in terms of an early election and with populists maybe gaining an even bigger share,” said DZ Bank analyst Andy Cossor.
“And for some investors it’s just the case of offloading the positions given the uncertainty.”
Italy’s anti-establishment 5-Star Movement is considering campaigning together with the far-right League if the country goes back to the polls, a 5-star source said.

Meanwhile, Spanish government bond yields hit fresh 2-1/2 month highs on Monday, hit by concerns over a potential snap election and also by Italian political uncertainty, which affected sentiment throughout Southern Europe.
Spanish Prime Minister Mariano Rajoy will face a vote of confidence in his leadership on Friday as corruption convictions handed down to dozens of people linked to his centre-right People’s Party (PP) threatened his six-year rule.
The yield on 10-year Spanish government debt ES10YT=RR briefly touched 1.537 percent, the highest since March 5, before settling at 1.52 percent; still up 6 basis points on the day.
