Australian bond futures prices are slightly firmer as weak US house sales data increase appetite for safe-haven assets.
US Treasury prices gained on Saturday, Australian time, after weaker-than-expected US housing data was released.
Existing-home sales in January fell 5.1 per cent to an annual rate of 4.62 million.
Global markets are confused as to whether this was caused by the severe cold weather or a sign of a bigger trend, Westpac senior market strategist, Damien McColough said.
"While we have tapering going on from the Fed, some US data are coming in weak and the market doesn't know if it's temporary, and weather-related, or a sign of harder times to come," he said.
"Everything is range-bound at the moment."
