The big four banks will face stronger competition from second-tier banks, which will be able to offer cheaper home loans and sharper deposit rates when the regulator moves to even the playing field for banks in the weeks ahead.
The Australian Prudential Regulation Authority is expected to reduce the relatively high risk weighting applied to mortgages issued by smaller banks that determines how much capital they are required to hold to support their lending. That would narrow a key 10 percentage point regulatory advantage that allows the big banks to hold less capital.
