$A flat ahead of inflation data

The Australian dollar is little changed as traders wait for the latest official inflation data.

At 1730 AEST on Tuesday, the local currency was trading at 93.93 US cents, up from 93.92 cents on Monday.

There were no major economic data releases to trigger activity in the Australian dollar, CMC Markets chief market strategist Michael McCarthy said.

"It's been a tough day for currency traders with very little activity and movement," he said.

"Both buyers and sellers were on strike."

The market had been focussed on a speech by Reserve Bank governor Glenn Stevens, however it contained no new information, Mr McCarthy said.

"It's reasonable that his speech produced no market reaction because there's not a lot to say ahead of some major data releases," he said.

The Australian Bureau of Statistics will release its inflation read on Wednesday.

US inflation figures are also due out on Tuesday night, Australian time, which is expected to influence the US dollar and have flow-on effects for the local currency.
