The Government's housing affordability package, announced in the May federal Budget, was introduced into Parliament yesterday. Major planks are: the First Home Super Saver Scheme, will allow first home buyers to save for a deposit inside their superannuation fund; a plan, backdated to 1 July 2016, to allow older Australians to contribute the proceeds of the sale of their family home to superannuation; and (while negative gearing was untouched) deductions relating to residential investment properties were targeted. Partners in the banking practice at PricewaterhouseCoopers, in their quarterly Major Banks Analysis for June 2017, observed that banks' margins "were supported by the substantial repricing of investor and interest-only home loans over the first half of 2017 … [however], as future origination begins to skew more towards owner-occupiers and principal and interest borrowers who will be offered lower rates, we expect that in the absence of another catalyst for repricing, mortgages may shift from tailwind to headwind on overall NIM." PwC qualified this conclusion with a note that, "empirical evidence suggests discounts have been harder to get, especially for [investor] and [interest only] borrowers. … Even without headline price rises, NIMs may continue to find support as borrowers seeking to refinance investor and IO loans find conditions less favourable."
