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 rates by 0.25% p.a. on eligible variable-rate business loans. 

The rate change will apply to CBA Business Bank’s Variable Base Rate, Commercial Variable Base Rate, Residential Equity Rate, Commercial Residential Equity Rate, Overdraft Reference Rate, and Commercial Overdraft Reference Rate, flowing through to eligible variable-rate business lending products including BetterBusiness Loans and Business Overdrafts. 

These changes will be effective 9 October 2026.

CBA Group Executive Business Banking, Mike Vacy-Lyle, said the Bank remained focused on supporting customers as they navigate an uncertain operating environment.

“As inflationary pressures persist, many Australian businesses continue to face higher operating costs and tighter margins.

“We’re working closely with our customers to understand how these conditions are affecting them and where we can offer support. We encourage any business experiencing pressure to reach out early so we can work through the support options available, including assistance from our Business Financial Assistance team.”
