Commonwealth Bank has followed its rivals in lifting its variable mortgage rates, pleading increased funding costs.
Australia's largest lender says variable rates for owner-occupiers and investors will increase by 0.15 percentage points from October 4.
Westpac was the first major lender to move in the latest round of hikes - which have come despite the Reserve Bank this week once more holding the cash rate at a record low 1.5 per cent - followed by Suncorp, ANZ and now CBA.
ANZ has announced it will increase its variable home loan rates, following Westpac’s decision last week.
Variable interest rates will go up by 0.16 per cent of a percentage point, effective of September 27.
Westpac last week announced it would lift its own rates by 14 basis points from September 19.
But ANZ said customers in drought-declared areas of regional Australia would be excluded from the change.
ANZ group executive Fred Ohlsson said the rate hike had been a "difficult decision".
"The reality is it is more expensive for us to fund our home loans on wholesale markets and we also needed to balance the needs of all stakeholders," he said.
"There is no change to the effective rates of our home loan customers in drought declared regional Australia benefiting more than 70,000 of our customers.
"We wanted to play our part in keeping cash in regional towns impacted by the drought and we hope this will also assist both families and small businesses in these areas."
