Minutes from the Reserve Bank of Australia's (RBA) December meeting, where the central bank opted to leave the cash rate unchanged at 0.75%, showed it was "prepared to ease monetary policy further if needed."
"Members agreed that it would be important to reassess the economic outlook in February 2020, when the Bank would prepare updated forecasts," the meeting minutes read. "As part of their deliberations, members noted that the Board had the ability to provide further stimulus to the economy, if required."
"The minutes of the Reserve Bank of Australia's meeting clearly kept the door open for further easing," analysts at Mizuho Bank wrote in a note. "The dovish tone of the RBA should lead to a softer AUD/USD."
