Europe's main bourses though continued to slip in and out of the red after Asian and emerging markets had had weak sessions following warnings from both Canada and Mexico that NAFTA's days could be numbered.
"This seems consistent with the ECB starting to flag an exit from QE later this year the same way the Fed did six months before it ended it asset purchases," said Mark Dowding co-head of investment grade credit at Bluebay asset management.
The ECB's warning shot also helped reverse the overnight bounce by U.S. government bonds after China's regulator said a Bloomberg report on Wednesday that it was considering slowing or halting its U.S. bond purchases, was possibly "fake news."

There was also some relief from Japan, another source of pain for bond markets this week.

U.S. West Texas Intermediate (WTI) crude futures were at $63.84, up 27 cents. The contract reached a high of $64.08 per barrel earlier in the day, its highest since December 2014.
Sentiment was boosted by a surprise drop in U.S. production and lower U.S. crude inventories in official data on Wednesday.

U.S. production also fell by 290,000 barrels per day (bpd) to 9.5 million bpd, the EIA said, despite expectations of output breaking through 10 million bpd.
The drop, likely to be because of extreme cold weather that halted some onshore output in North America, was expected to be shortlived.
