Australia's economy grew 0.6 percent in the first quarter, for an annual rate of 2.5 percent, missing economists' estimates of 0.8 percent and 2.7 percent respectively. Inflation was 0.6 percent on average in the second quarter, just above a Reuters forecast of 0.5 percent.
Stevens said recent data is "consistent with global growth running a bit below average this year, with reasonable prospects of a pick-up next year."
The Australian dollar climbed to 89.53 US cents from 89.25 cents immediately before the announcement. The kiwi dollar dipped to 87.43 Australian cents from 87.71 cents. Some traders had been betting on the half-point cut by the RBA.
Stevens reiterated his view that the Australian dollar may fall.
"The Australian dollar has depreciated by around 10 percent since early April, although it remains at a high level," he said today. "It is possible that the exchange rate will depreciate further over time, which would help to foster a rebalancing of growth in the economy."
