SYDNEY, AAP – Australia’s share market has made a tame start to a shortened trading week after the 10-year government bond yield briefly surpassed three per cent.

The market was marginally higher and mixed as the bond market showed investors expecting higher rates sooner amid annual inflation of 3.5 per cent.

The 10-year government bond yield rose to three per cent earlier on Monday and was at 2.99 per cent at 1200 AEST.

Investment analysts have tipped attractive yields will soon lead investors to exit the share market for low risk bonds.

The higher yields follow the Reserve Bank last week dropping its patient language on raising rates.

The US Federal Reserve also revealed some policymakers want steeper rate hikes after a quarter of a per cent rise in March.

Investors will this week be monitoring the US first-quarter earnings season, while Russia’s ongoing war on Ukraine continues to complicate commodity prices.
