The RBA today released the minutes of its last meeting on September 3, when it held its cash rate steady. As well as the comment about another potential rate cut, the RBA said it is "reasonable to expect that an extended period of low interest rates would be required in Australia to make sustained progress towards full employment and achieve more assured progress towards the inflation target."
The RBA also discussed the fact that monetary policy easing is "widely expected" around the globe and that the US-China trade war has intensified downside risks to global growth.
Mike Shirley, a dealer at Kiwibank, says the RBA's position was little more than a statement of the obvious given a central bank will always be ready to cut rates should conditions make that necessary. Yet he said it was perceived as "mildly dovish."
The market is also speculating that the RBA may be poised to cut rates again at its next meeting on October 1 as governor Philip Lowe is giving a speech on September 24, Shirley says.
Each of the RBA's cuts in June and July, the first since August 2016, had been preceded by Lowe giving a speech.
"We're certainly seeing that reflected in the interest rate curves both there and here."

Financial markets are also watching the situation in Saudi Arabia after its oil production facilities were attacked at the weekend with Yemen's Houthi rebels claiming responsibility.
The Tokyo market was closed for a holiday yesterday, resulting in "a bit of noise around the Asian open" because today was that market's first chance to react, Shirley said.
Pentagon officials have urged caution after Saudi Arabia said Iranian weapons were used in the attack and US President Donald Trump has publicly dithered between making a retaliatory strike against an Iranian oil facility and seeking to cut a deal with Iran.
