Australian Banks Pay $55 Million Over Offset Account Failures

The Australian Securities and Investments Commission (ASIC) revealed that eight banks paid more than $55 million in compensation to mortgage holders between September 2023 and August 2025. A review of 204,000 loans across institutions including ANZ, Commonwealth Bank, Westpac, Macquarie, ING, HSBC, Great Southern Bank, and AMP Bank found systemic weaknesses in the setup and monitoring of offset accounts.

ASIC found that manual staff errors caused 86% of these failures, such as incorrect account delinking during refinancing. These errors led customers to unknowingly pay more interest and extend their loan repayment periods; in one case, a borrower paid over $3,500 in extra interest in a single month. ASIC Chair Sarah Court stated that some banks are "not getting the basics right" and noted that many failures remained undetected until the regulator intervened.

Simon Birmingham of the Australian Banking Association defended the industry, stating that banks managed accounts correctly in over 99% of cases. However, Treasurer Jim Chalmers emphasized that "Australians deserve better from their banks" during the current cost-of-living crisis. ASIC expects total compensation to increase as remediation continues and has urged customers to verify their account links through their lenders.
