A business banker trained at Rural Bank and Bendigo Bank takes the reins at Adelaide's People's Choice Credit Union next month, with CFO Steve Laidlaw taking over as the new boss.Laidlaw's business banking experience is not too common among mutual bank CEOs. And nor did Laidlaw signify much appetite for business banking when posed with this option at the end of an interview yesterday.The standardised capital formula puts smaller banks at too much of a disadvantage in this field, Laidlaw said."For us, the focus will always be retail."Look, we've got our vision pretty right, which is to be the most effective financial services provider to people and communities."As reported yesterday, People's Choice walks into the top five banks by customer satisfaction, with a rating of 93.1 per cent."There's a lot of change going on; we'll embrace that, both the sector and People's Choice," he said.Laidlaw cited research on the young "new millennials" cohort."When asked what corporations should do, in the top three things is producing a valuable social good."People's Choice, a thriving mutual, meets this in spades. Laidlaw values its social contribution as ten times that of major banks, adjusted for scale."Mutuals take pride in having a deeper relationship with members," he said.A deeper investment in the credit union's digital footprint is underway.Laidlaw outlined a self-reliant model."We are trying to build that capability in house."Asked to consider the merit of core business partners - Cuscal, DataAction and CGU - Laidlaw said he must explore the topic with management when he starts in a month."I think we do have some good partners."
