The Australian Bankers Association has called for an end to regulation of interchange fees on debit and credit cards by the Reserve Bank of Australia. Instead the association says that interchange fees should be set on commercial terms by the market, helping to restore regulatory certainty, and reducing the risk of sub-optimal levels of investment and innovation. In its submission to the review of payments system reforms American Express said that they had given merchants a significant and ongoing financial benefit, estimated to be at least $2.2 billion since 2003, but that there was no evidence of any decrease in the price of goods and services resulting from this.
