The New Zealand Bankers' Association says the Australian Prudential Regulation Authority's move to make the big four Australian banks reduce their non-equity exposure to their New Zealand subsidiaries highlights the need for more coordination of trans-Tasman bank failure management plans, notes interest.co.nz. New Zealand Bankers' Association CEO Kirk Hope told interest.co.nz banks still have concerns: "What is necessary is a more coordinated and robust trans-Tasman (bank) failure management regime enacted through legislative change that would reduce the need for independent and unaligned regulatory measures such as APS222 in Australia and OBR and outsourcing in New Zealand," Hope said. Australia and New Zealand Banking Group has joined about 30 other major tech firms and financial institutions, "banding together to explore how blockchain technology may further their businesses and potentially replace the dated international money transfer system", the AFR reports. ANZ will join the likes of IBM, Intel, the London Stock Exchange, State Street, Wells Fargo, Cisco, CLS, Digital Asset, Fujitsu, IC3, Mitsubishi UFJ Financial Group, SWIFT and VMware, in a project called "Hyperledger".
