The ANZ-branded remnant of the bank's former Esanda finance arm "will suspend providing new secured asset finance loans for retail customers in Australia while it undertakes a detailed review of its business," the bank announced on Friday.In a media release, ANZ's managing director for retail distribution Catriona Noble said that "given the increased technology costs required to effectively compete in the secured consumer asset finance market, we have decided to suspend all new loans while we conduct a detailed review of the business."The announcement "covers both direct and broker originated channels," ANZ said.ANZ said it would continue to service existing consumer asset finance customers and "continue to provide customers with access to personal loans during the suspension."The bank said its asset finance product for commercial customers was not affected.Consumer asset finance, the bank said, "includes loans provided for motor vehicles, boats and caravans for retail customers." ANZ added that its secured consumer asset finance product "represented less than one per cent of revenue within our broader Australian business."
