George Frazis has had a number of roles in several different banks during his 17 years in banking. That's handy, because he has to solve a number of problems in several different parts of the bank he is about to lead.Bank of Queensland announced yesterday that Frazis will take over as chief executive in September. A month later he will be joined by a new chair, when Patrick Allaway takes over from Roger Davis.Frazis is moving from Westpac, where he was CEO of the consumer bank. He has also served as CEO of Westpac New Zealand and CEO of St George Bank. He has held senior executive positions at NAB and Commonwealth Bank.BOQ's half-year financial report revealed that the bank faces difficulties on a number of fronts. Its core branch lending business is in decline, its branch network is shrinking and its lending processes and digital customer offering need an overhaul.The bank's income and profit were down, costs and loan impairment expenses were up and the ROE was a dismal 8.8 per cent. Its common equity tier 1 ratio fell and it cut its dividend.With little business growth in prospect it faces higher costs as it adjusts to the post-Hayne regulatory environment. And in December the anti-money laundering regulator Austrac issued a report that identified "potential compliance contraventions" at the bank.The branch network is under stress, with 11 closures during its latest half-year.The bank has acknowledged that it is having difficulty growing its branch network, some of which operates as a franchise system, because potential owner-managers are uncertain about the future of the industry.It has also acknowledged that its lending processes are overly complex. It has started an automation process that involves the use of automation and robotics.Other areas of weakness are its internet and mobile offerings, which it has conceded are "not delivering the customer experience customers expect in 2019".If that isn't enough for Frazis to work on, he has an unwanted life insurance business, St Andrew's, that was to be sold to Freedom Insurance Group. The sale fell through after Freedom's management was mauled in royal commission hearings and the company later collapsed.
