ANZ Bank is the only big four bank that will not pass on the full value of the Reserve Bank's 0.25 percentage point reduction in official interest rates to home loan customers, blaming the decision on higher funding costs.

Instead, ANZ Bank will reduce its home loan rates by 0.19 of a percentage point, with its benchmark rate for owner-occupiers falling to 5.37 per cent.

ANZ's move came after National Australia Bank, Westpac, Commonwealth Bank and Bank of Queensland said they would pass on the full RBA cut to their home loan customers.

ANZ, which also posted a 24 per cent slump in profit and cut its dividend on Tuesday, said its decision on interest rates struck the right balance between the interests of customers and shareholders.
