Following the Reserve Bank of Australia’s (RBA) decision to increase the official cash rate by 0.25% per annum (p.a.), CBA will increase home loan variable interest rates by 0.25% p.a. 

All CommBank home loan variable rate changes announced today will be effective 9 October 2026.

CBA’s Group Executive Retail Banking, Angus Sullivan said the RBA’s decision comes amid persistent inflation and continued global uncertainty, both contributing to broader economic pressures.

“Each customer’s circumstances are different, and our teams are ready to provide support, help them understand their options and consider what might work best for their situation,” Sullivan said.

“For some customers, the immediate priority might be understanding how their repayments and budget may change and where adjustments can be made. For others, it may be having a more detailed conversation with us about their finances.”

Customers who are concerned about their financial circumstances can contact CBA through their usual banking channels. Those experiencing financial difficulty can also connect with CBA’s Financial Assistance Solutions Team, who can talk through their situation and discuss what support may be available.

For customers seeking greater certainty around repayments, a fixed rate home loan can provide stability for a set period, while a split loan combines this with the flexibility of a variable rate.

“Customers have different needs and goals, and we encourage anyone interested in understanding their options to speak with a Home Lending Specialist about what may be right for them,” Sullivan said.

Quick tips to help customers manage their finances:

  1. Customers can estimate how much their home loan repayments may change via the Home Loan Repayments Calculator.
