ANZ Group has agreed to pay its largest-ever penalty—a A$240 million fine—following a landmark enforcement action covering both institutional bond trading misconduct and serious retail banking failures. The case underscores the growing regulatory scrutiny of financial institutions, as authorities clamp down on misconduct that undermines both market integrity and consumer trust.

What Went Wrong: Bond Trading and Data Misreporting

The investigation revealed misconduct during a A$14 billion government bond issuance in 2023. Instead of trading gradually to minimize market disruption, ANZ sold large volumes of 10-year government bond futures around key pricing points, creating downward pressure on prices. At the same time, the bank misreported trading turnover data for nearly two years, misleading government authorities and eroding confidence in Australia’s debt markets.

Such behavior not only damaged the credibility of bond markets, but also risked increasing the government’s cost of raising capital. The scale of the misconduct highlights systemic weaknesses in ANZ’s risk controls and internal governance structures.

Retail Customers Took the Hit

The case also exposed widespread failings in ANZ’s treatment of retail clients. Around 65,000 customers were impacted over several years. Issues included charging fees to deceased customers, failing to honor promised interest rates, mishandling hardship notices—some ignored for years—and making misleading claims about savings products.

These lapses illustrate how operational failures and poor oversight can translate into direct financial harm for households, raising questions about culture, accountability, and governance within one of Australia’s largest banks.

Regulatory Fallout and Strategic Wake-Up Call

ANZ has committed to sweeping reforms under its new leadership team. The bank is preparing a remediation plan to be submitted to regulators by the end of September 2025, backed by A$150 million in funding. Plans include restructuring operations, cutting approximately 3,500 jobs, and strengthening systems to improve transparency and customer service.

For the broader financial system, the case serves as a warning that regulators are prioritizing both market conduct and consumer outcomes. The record fine sets a new benchmark for penalties in Australia, signaling that tolerance for systemic misconduct has diminished sharply.

Looking ahead, the test for ANZ will be whether it can deliver measurable change in governance, compliance, and culture. Market participants and regulators will watch closely to see if these reforms rebuild investor confidence and set higher standards across the banking sector.
