The Australian bond market is weaker following moves in US bond prices, which fell after comments by the US Federal Reserve on potential interest rate rises.
St George senior economist Jo Horton said US Treasury prices slid "as a lift in sentiment continued the reversal in safe-haven flows", following comments from Fed chair Janet Yellen.
"(The) speech by Fed Chair Yellen reiterated a (rate) hike later this year would be appropriate, but noted the economic outlook remained uncertain," Ms Horton said.
