The Commonwealth Bank has become the latest of the big four banks to hike home loan rates, raising borrowing costs for owner-occupiers and property investors just hours after rate hikes from Westpac and ANZ.

The nation's largest bank will raise interest rates on standard variable home loans by 3 basis points to 5.25 per cent effective from May 8. Investors will see a 24 basis point hike to 5.80 per cent.

CBA will also raise borrowing costs on interest-only loans. Rates for owner-occupiers will increase by 25 basis points and 26 basis points for landlords.

The bank blamed "rising costs and regulatory responsibilities" for the rate hikes.
