HSBC received about 950 reports of unauthorized transactions between January 2020 and August 2024, resulting in customer losses of about A$23 million ($14.6 million), according to an Australian Securities and Investments Commission statement Monday. Around A$16 million of this occurred in the six months from October 2023 to March 2024.

“ASIC alleges HSBC Australia failed to have adequate controls in place to prevent and detect unauthorized payments and failed to comply with its obligations to investigate customer reports of unauthorized transactions within the specified time frames required, and to promptly reinstate their banking services in a timely manner,” according to the statement.

ASIC said the bank on average took 145 days to investigate client reports that they had been scammed, the statement said. ASIC said HSBC Australia’s failings were widespread and systemic.

A spokesperson for HSBC didn’t immediately reply to a request for comment.
