The Reserve Bank of Australia has cut its key interest rate, citing weaker commodity prices in a global market where the outlook for economic growth "has softened".
The Australian dollar has dropped against the greenback and the New Zealand dollar.
"The outlook for growth in the world economy has softened over recent months, with estimates for global GDP being edged down, and risks to the outlook still seen to be on the downside," Governor Glenn Stevens said in a statement published on the RBA website.
"Key commodity prices for Australia remain significantly lower than earlier in the year, even though some have regained some ground in recent weeks," he said.
The Australian dollar dropped to US$1.0309 after the statement was released, from US$1.0368 immediately before. The kiwi dollar gained to 80.35 Australian cents from 79.86 cents.
