On Tuesday 4th December 2018 the RBA decided to leave the official interest rate at 1.5%. This means that the official interest rate will be stable for at least two months since the RBA does not meet in January. Their next meeting will be in February 2019.
Even though the RBA has kept rates on hold, it sometimes does not stop lenders from increasing their rates out-of-cycle. It will be interesting to see how the first few months of 2019 play out.
The RBA state that they see economic conditions improving and that the next interest rate movement is likely to be up.
