The Australian dollar is slightly lower on a quiet day of trading.
At 1200 AEDT on Tuesday, the Australian dollar was trading at 104.74 US cents, down from 104.78 US cents on Monday.
Commonwealth Bank currency strategist Joseph Capurso said a lack of news meant the Australian dollar had moved very little on Tuesday morning.
"There's been hardly any movement at all," he said.
"There hasn't been any news that's pushed things around."
The Australian dollar would remain around the same levels throughout the week despite a US Federal Reserve meeting commencing on Tuesday night (AEDT), he said.
The Fed is expected to announce further stimulus measures following the two-day meeting.
"That may move things around, but even that, I think, will just go through to the keeper," he said.
"I think everyone's already expecting the announcement so it shouldn't move the Aussie dollar very much."
Meanwhile, Australian bond futures prices were higher at noon.
At 1200 AEDT on Tuesday, the December 10-year bond futures contract was at 96.960 (implying a yield of 3.040 per cent), up from 96.930 (3.070 per cent).
The December three-year bond futures contract was trading at 97.400 (2.600 per cent), up from 97.370 (2.630 per cent).
