Roughly 260 billion euros ($254 bln) of euro zone government bonds carried negative yields as of end-September, Tradeweb said, down from around 542 billion euros at end-August.

Negative-yielding bonds made up 3.2% of a total market worth around eight trillion euros on the Tradeweb platform, versus almost 7% in August. The September figure was the lowest since at least 2016, when Tradeweb started compiling the data for Reuters.
