The Australian currency was higher at Monday noon following reassurances by the Federal Reserve chief about the American economy.

At midday, the local dollar was exchanging at $US0.9018/20, an increase from Friday's finish of $US0.8869/71.

Since 7am (AEST), the Aussie ranged from $US0.9002 to $US0.9030.

The Australian Bureau of Statistics (ABS) published business indicators data during the local session.

Company gross operating profits, in current prices, increased 18.9 per cent in the June quarter, seasonally adjusted, and were 27.5 per cent higher over the year.

ICAP senior economist Adam Carr predicts the Aussie to stay above the 90 US cent mark this week.

"Obviously there's a very decent lift following Bernanke's and the US GDP numbers and that's held for the remainder of the session," he said.

Last Friday night (AEST), the Federal Reserve chairman Ben Bernanke said the central bank stood ready to act if needed to spur slowing growth, and downplayed concerns the economy might slip back into recession.

The US Department of Commerce also announced that gross domestic product (GDP) expanded at an annualised 1.6 per cent in the three months to June, short of its earlier estimate of 2.4 per cent but better than the market prediction of 1.4 per cent.

"I think we'll push a little bit higher and most people will sit on their hands for the rest of this session and await data tomorrow and certainly GDP numbers on Wednesday," Mr Carr said.

He expects the Aussie to range from $US0.9011 to $0.9030 within the day.
