National Australia Bank boss Andrew Thorburn says the banking giant's mortgage rates are under review after Westpac moved to lift owner occupier home loan rates.
Westpac on Wednesday said it would lift its variable mortgage rates by 0.20 percentage points from November 20 as it passes on some of the cost of new capital requirements, sparking speculation its three major rivals will follow suit.
Asked at a business lunch whether NAB would follow suit, Mr Thorburn said the bank's rates were under review.
"I think we are very comfortable with the position we've got but obviously, as with all products and services, it's something that you react to the market and review on an ongoing basis," he said.
The Commonwealth Bank says it is yet to decide on whether to follow rival Westpac and lift mortgage rates for owner occupier home loans.
"We've made no decision on our rates, which remain on hold," a statement from the Commonwealth Bank said.
Westpac has announced plans to increase its standard variable rate by 20 basis points in response to a push by the banking regulator for banks to bolster their balance sheets.
