Nationals Senator Matthew Canavan has written to the Australian Competition and Consumer Commission asking it to investigate the decision by the major banks to close the accounts of bitcoin companies, the Australian Financial Review reports. Canavan, who sat on a recent Senate committee inquiry into digital currencies, complained that the banks were putting the viability of the industry at risk. An ACCC spokesperson confirmed that the letter had been received and was being considered. The Reserve Bank has appointed Michele Bullock to the position of assistant governor business services. Since 2010 Bullock has held the position of assistant governor currency. In her new role she will assume the additional responsibility for the RBA's banking and payments settlements departments upon the retirement of Keith Hall, assistant governor banking and payments, in December. Consumer finance company Thorn Group has appointed Peter Fosberg to the role of chief financial officer. For the past five years Fosberg has been group CFO at St Vincent's Health Australia, which operates six public and eight private hospitals, aged care, research and associated medical services. He has also held senior finance roles in manufacturing and professional services.
