At Bank of Queensland we can "now legitimately call ourselves a national bank", says the bank's new chair, Roger Davis. He was speaking at BOQ's annual meeting yesterday.The regional bank's ambitions are strictly national, however."We won't be leaving Australia in search of new hunting grounds," he said.Domestic acquisitions remain an option."A platform for growth is our focus on new customers, who can be acquired either through organic growth or by acquisition, and on ongoing service and product enhancements," Davis said. BOQ acquired Virgin Money earlier this year and the Home Building Society, in Perth, in 2008.The bank's chief executive, Stuart Grimshaw, used his address to pitch once more for regulators to redress what he called the "capital imbalance" that favours big banks, which allocate only one-third as much capital, on average, to a home loan as BOQ."While some may argue that the major banks have more sophisticated risk modelling, I don't think it's unreasonable to question whether such a stark differential is really warranted," Grimshaw said. "We think the Financial System Inquiry should seek to address such inequities and give the regional banks and smaller financial institutions a fair go."
