Low wages growth and low (and falling) credit growth are constraints facing the entire banking sector, Shayne Elliott, chief executive of ANZ said yesterday.Outlining ANZ's half year profit to March 2017 yesterday, Elliott mused on macroeconomic factors hindering the bank's pursuit of growth in its revenue and profits."Credit growth of six per cent, almost exclusively driven by housing, coupled with wages growth of two per cent, is not sustainable or desirable," Elliott said."If this continues, this will curtail credit growth to five per cent or lower," he said."It's hard to think of a scenario today that lifts wage growth … we're setting our bank up for both [credit growth and wages] going to be lower for longer."Responding to one sell-side analyst at an investor briefing, Elliot explained that ANZ moved to "slow down" growth in home loans "six to nine months ago, we allowed our market share to shrink a bit."We've seen an impact of that in our revenue. Since then, we're more comfortable with our position and seen growth."ANZ's mortgage market share at March 2016 was 16.1 per cent (of all banks mortgage funding) APRA data shows. This more or less returns ANZ to its market share where it was a year ago, and is 13 basis points better than a low point at its September 2016 full year result.Of APRA's most recent macroprudential measures, centred on muting lending for interest only loans, Elliott said "we'll use that as an opportunity to improve the quality of the book. We'll see more granularity, more risk-based pricing, it's a good thing."Fred Ohlsson, group executive Australia, group executive, said the bank had "plans in place to make sure we hit the regulatory requirement."Ohlsson parried suggestions the APRA measures may impede the bank's capacity to maintain market share."We're similar to Commonwealth Bank and NAB," he said."The biggest interest only [lender] we see is Westpac," Ohlsson said.
