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 15 May 2026.

CBA Group Executive Business Banking, Mike Vacy Lyle, said the Bank remains focussed on supporting business customers through the current economic environment.

"Inflationary pressures and global economic conditions continue to shape the operating environment for Australian businesses,” he said.

“We know many business owners are dealing with higher costs, and that consecutive interest rate increases this year are adding further pressure to cash flow and margins for some businesses.

“Our priority is to support customers as they navigate these conditions. We’ve been reaching out to many of our business customers to understand how they’re tracking and how we can help.

“Having these conversations early is important, and we encourage anyone who needs assistance to contact our dedicated Business Financial Assistance team.”
