Bond futures prices have surged on the back of disappointing economic data out of the US.
Growth in the US manufacturing sector slowed for the fifth straight month in March.
And US businesses increased nonfarm payrolls by just 189,000 jobs in March, payrolls firm ADP said, the first time since January 2014 that fewer than 200,000 jobs had been added.
The weak data gave US bond prices a boost, and the Australian market followed suit, ANZ economists said.
“US employment and manufacturing data undershot market expectations, driving a solid rally in US Treasuries,” they said.
