ANZ chief Shayne Elliott on Monday indicated that the bank is preparing to lift the lid on instances of misconduct that were not previously not publicly known.In a letter to ANZ staff, Elliott described as "confronting" a litany of misconduct that the bank has included in its formal submission to the Hayne royal commission."Although many of the issues in our submission are known and have been or are being fixed - seeing them all in one document is confronting," Elliott told staff in the letter.?"Of course, it would be easy to lay the blame on a few bad apples or to say that these are largely historical technical glitches resulting from large complex IT systems."That would be wrong."For me, it's completely unacceptable that we have caused some of our customers financial harm and emotional stress."Elliott says in the letter - published on the ANZ Bluenotes website on Monday afternoon - that he hopes the royal commission will serve as a watershed moment in restoring the trust of customers and the community."Time and time again, I heard tough questions about how quick we are to pass on interest rate rises as opposed to reductions, the size of our profits, the amount of money senior executives earn, how hard it can be to switch banks, the unfairness of many fees and charges, how hard it can be for small businesses to get loans, the potential conflicts of interest in the broader finance sector and, importantly, how hard and slow it can be to get a result when things go wrong," he told staff.?"This isn't a complete list but goes some way to understanding why the community's trust in us has diminished."Each of the major banks is expected to use the royal commission as a confessional to air new cases of behaviour that failed to meet community expectations.National Australia Bank yesterday invited customers interested in making submissions to commissioner Justice Hayne to contact the bank.
