AMP Bank is the latest to lift its variable lending rates, "for all owner occupiers and investors." The changes include an increase of 8 basis points for owner occupied principal and interest, 17 basis points for owner occupied interest only, 17 basis points for investment principal and interest and 17 basis points for investment interest only, the bank said. The changes are effective 13 July 2018 for new business and 16 July 2018 for existing business. AMP Bank Group Executive Sally Bruce said "these changes are driven by an increase in funding costs … We have held off passing this cost on to customers for as long as we can and in fact have not increased interest rates for existing customers since June last year. The fifth round of hearings - on superannuation - will kick off on Monday, 6 August, the Royal Commission into misconduct in banking and financial services announced yesterday. "Further information on topics to be covered in round 5 will be published prior to the hearings commencing," the commissions said. Andrew Thorburn, managing director of National Australia Bank, has given a long and defensive interview to the AFR's BOSS magazine, the first of the long form CEO interview genre to appear since the Hayne royal commission commenced its work earlier this year. "We're seeing a slice - an accurate and painful one - of cases where things have gone wrong ... [but] our people's behaviour, commitment and ethics is overwhelmingly positive" Thorburn told the magazine.
