Australia's biggest lender said loan impairment expenses increased by A$586 million ($409 million) and business credit growth slowed, reflecting strong inflationary pressures, rising interest rates and a decline in property prices.
"We expect business credit growth to moderate and global economic growth to slow during 2023," said Chief Executive Officer Matt Comyn.
"We are conscious that many of our customers are feeling significant strain from rising interest rates, alongside the rising costs of electricity, groceries and other household items,” Comyn said in an analyst and investor briefing.
Higher interest rates are yet to hit many CBA mortgage customers as many cheaply priced fixed rate loans are expected to come off by the end of the year.
The bank also announced it would buy back additional shares worth A$1 billion, on top of a A$2 billion share buy-back announced last February.
