Travel sickness: Consumers overpay millions on foreign money, says ACCC

I think the ACCC may have missed the boat on this one. A few years ago, the banks started effectively closing down most of the small ethnically based FX dealers. It was common in many ethnic communities for there to have been between 10 - 20 FX brokers running their businesses at very low margins. They saw the provision of FX services as more of a community service rather than a money making venture.
The banks started closing down these operations under the guise of anti-money laundering and anti-terrorism laws. I recall that virtually all Nepalese FX dealers in Australia had to close down because the banks refused to deal with them. It was particularly problematic as Nepal was at that time trying to rebuild after the Gorkha earthquake. I was also puzzled by this as I have never associated Nepal with global terrorism! Having said that, maybe it isn't too late for the ACCC to go back and investigate the conduct of the big banks under section 46 the misuse of market power provisions.
