ANZ Bank chief executive Shayne Elliott has vowed to tackle any inappropriate behaviour at the bank following allegations by two former traders of impropriety.
In an email sent to staff on Tuesday, Elliott said the bank's conduct underpins its reputation, and its reputation with customers and the community is "everything".
"My commitment to you is that we will tackle any instances of unacceptable behaviour head-on, wherever it happens at ANZ," Elliott said.
Elliott, who took the reins from Mike Smith on January 1, acknowledged there had been some problems within its Global Markets division, which were quickly addressed.
"I want to be upfront with you. There have been challenges in small pockets of Global Markets and we have investigated and dealt with the conduct issues as we became aware of them," he said. "While we know many of the allegations made by these former employees are not true, we can't tolerate unacceptable behaviour in any part of our business."
