LONDON, Aug 13 (Reuters) - Euro zone government bond yields dipped on Tuesday, with Germany’s 10-year benchmark reaching new lows as a range of concerns from uncertainty over Brexit to political turmoil in Italy drive investors into safe-haven assets.
A survey of business sentiment in Germany is expected to add to a dismal image of the bloc’s largest economy. The ZEW survey’s expectations measure is forecast to be its worst since 2011.
“Given all the negative news in recent days and weeks it looks like there could be another major drop,” said Daniel Lenz, rates strategist at DZ Bank.
“The ZEW index hasn’t been the most important but this time everyone is very nervous and looking at all kinds of data.”
Ten-year German government bond yields fell to -0.613% in early trade, while its 30-year notes outperformed and were down four basis points at -0.135%, very close to all-time lows ,.
Economic woes and expectations of more monetary easing are pushing down bond yields globally. Japanese 10-year yields hit three-year lows.
There are now nine sovereigns with 10-year bonds that trade at market prices implying a negative yield to maturity. The nominal stock of government debt with negative yields is about $15 trillion, said Fitch in a note on Monday.
Italian yields were down up to six basis points across the curve, falling for the second straight trading day after sharp rises seen on Friday on a call from League leader Matteo Salvini to dissolve the government.
Salvini is pushing for a no-confidence vote this week to bring down the government his party formed with the 5-Star Movement (5SM) last year, while opposition parties would prefer to wait until Aug. 19-20.
The decision lies with the heads of political groups in the Senate.
5-Star is not seeking a deal with the opposition to delay new elections, but the timing of the vote must be decided by the head of state, party chief Luigi Di Maio said on Monday.
Italy’s 10-year yield fell to 1.69%.
