Europe has become the epicentre of the pandemic again in recent weeks. Markets, which had been relatively calm now have to weigh the impact additional measures may have.
"It's just building, that story of the pandemic not being quite over in Europe and that's a knee-jerk flight to quality. That's why you're seeing Bunds performing," said Peter McCallum, rates strategist at Mizuho.
Germany's 10-year yield , the benchmark for the euro area, at one stage fell to -0.344%, a drop of about 6 basis points, reversing early-session rises.

Little attention seemed to be paid to Bundesbank president Jens Weidmann who publicly contradicted the European Central Bank's official line. He said inflation may stay above 2% for some time and that the ECB should avoid any commitment to keeping the money taps open.
Prior to the lockdown announcements, ECB president Christine Lagarde said high inflation would fade so the bank should not tighten policy. She also hinted at continued bond purchases next year. read more
