Three of the country’s largest banks have slashed their fixed mortgage rates, fighting to win new customers by allowing borrowers to lock in longer-term interest rates of less than 5 per cent.
Commonwealth Bank of Australia, National Australia Bank and Westpac Banking Corp on Wednesday became the latest banks to cut fixed rates, each giving borrowers the chance to lock in historically low rates over the longer term.
