Only a tiny proportion of mortgage broking customers would be willing to pay $2000 for the service, a finding the industry says proves that any shift recommended by the Hayne inquiry to a customer-pays model would reduce competition and enhance the market power of the big banks.

The $2000 is equivalent to the average upfront commission brokers now pay banks for settling a mortgage — but a survey by Momentum Intelligence found 96.5 per cent of consumers who use or intend to use mortgage brokers would not be willing to pay the fee.
