The Australia and New Zealand Banking Group (ANZ) has increased its unaudited cash profit by 4% to A$5.4bn for the nine months ended 30 June 2015, but faces higher bad debt charges.

The bank has reported an unaudited statutory net profit of A$5.58bn, an increase of 11%.

Customer deposits saw a rise of 9.5% (+5% FX adjusted), while net loans and advances increased by 7.7% (+5.4% FX adjusted).

The Australia division of the bank has seen customer numbers increasing by circa 5% in retail as well as commercial operations, with the retail unit posting strong growth in both home lending and credit cards.

The New Zealand arm has delivered above market performance in mortgages, business lending and deposits.

The bank expects its total impairment charge for the current financial year-ending September to be nearly A$1.2bn, or 21 basis points as against 19 basis points a year earlier.

ANZ CEO Mike Smith said: "Economies in our key markets have slowed a little compared to previous years and global conditions remain challenging. In these circumstances we are continuing to sharpen our focus on the management of capital and on the control of expenses.

"Our super regional strategy continues to provide us with differentiated sources of revenue and future growth options and it is underpinning our performance in every part of the business.

"Our Australian Retail and Commercial businesses are continuing to outperform peers particularly in mortgages and are delivering consistently strong performance. We have shifted gears in our New Zealand business over the past few years and are seeing further benefits in terms of both market share growth and productivity."
