A Royal Commission style inquiry into Australia's banks will bubble along for a while yet, the Australian Small Business and Family Enterprise Ombudsman not yet done with even its first tranche of investigations into the sector.Kate Carnell, the ombudsman, told Banking Day her office was still working on a number of the loan files selected for a detailed study for an inquiry ordered by the Turnbull government in August."We plan to do regular public reports on how the banks are going," Carnell said yesterday.These may be half yearly or as often as quarterly, with the ombudsman the arbiter of what topics and when, though subject to references from the government.The ASBFEO, which finished in mid December but reported only on Friday, produced few surprises in a report with a list of 18 must-dos, most of them aimed at the industry and subject to short time frames.A primary political task, pursued by Carnell and her crew, was to review a selection of cases submitted to the Parliamentary Joint Committee Inquiry into the Impairment of Customer Loans over 2015 and 2016. Put differently, this was retread of Commonwealth Bank and ANZ bashing in the main, in some cases looking at dusty, tattered files. The ASBFEO selected 23 cases for close study.The ASBFEO seems, as yet, to have landed no real punch on any bank and took care not to name any in its report"About a third of these cases were simply poor business decisions where the bank appears to have acted reasonably," the report said.Another third it styled as "a mixture of poor business decisions and poor bank practice."The final third, all still under close scrutiny, produced "very real issues where bank conduct is unacceptable and possibly unconscionable."Any inference that this most colourful third are all Bankwest matters was one Carnell would not endorse, or even engage with, on the grounds "it would be wrong to comment on individual cases."In reality, each one of these will be documented to some degree on the website of the Joint Committee and maybe discoverable in court records, points Banking Day did not put to Carnell.Commonwealth Bank, the owner of Bankwest since 2008, relied on its media blackout ahead of next week's half year profit to avoid any comment on the report of Carnell's inquiry.One forum for banks to explain their response to the report of the ombudsman is a different set of quarterly hearings into banks, run by the economics committee of the House of Representatives.
