LONDON: Southern European government bond yields are hovering near record lows as investors anticipate a fresh round of European Central Bank stimulus to help jumpstart an economy that has had a bumpy recovery from the depths of the COVID-19 crisis.

Italian 30-year government bond yields hit a new record low on Monday while Spanish and Portuguese borrowing costs were also hovering around one-year lows, with their 10-year yields heading back towards zero.

This reflects a slower-than-expected economic recovery in Europe and remarks from key policymakers that suggest the need for further monetary and fiscal stimulus, analysts said.

"The main reason is the ever rising probability of ECB support, especially an extension of quantitative easing," said ING rates strategist Antoine Bouvet.

"Recent remarks by (ECB chief economist) Philip Lane and (ECB executive board member) Isabel Schnabel does suggest this is an environment for duration and spreads," he added.

Indeed, the long end of Italian and Spanish bond curves have been particular performers, with Italian 30-year yields dropping seven basis points on Friday alone to 1.60pc and down about 40 basis points over the past month.

It hit a new record low of 1.598pc on Monday.

Benchmark 10-year yields for Spain and Portugal are at 0.17pc and 0.18pc respectively, with analysts refusing to rule out a first-time dip into negative territory for this debt.

Pictet Asset Management chief economist Frederic Ducrozet pointed out that the ECB's Lane used the word "uncertainty" 11 times and the word "fiscal" 16 times in a recent Wall Street Journal interview.

"That's all you need to know about the ECB's outlook right now," he said on Twitter.

Meanwhile, the economic divergence with the United States continues apace, and bond markets are reflecting this.

The spread between German Bund yields and their US Treasury counterparts is at its widest since March on 132 basis points.

"The US has been doing a lot better economically in this recession than Europe, but there is a lot of hard data this week that should give us a better picture," said Bouvet of ING.

It will take awhile for the effects of the upcoming presidential election and mooted fiscal package to make themselves clear, he added.

Later this week, there's bond auctions from Italy, the Netherlands, Germany, Portugal, France and Spain in a busy week for debt supply.
