Interchange fees are an extremely controversial issue. CBA strongly opposes any government intrusion into the market pricing of interchange fees. The debit and credit card markets are extremely competitive at the card issuer, merchant bank and card network levels. Governmental intrusion into the setting of interchange fees is wholly unwarranted and, like other government intrusion into properly functioning markets, will have undesirable and unintended consequences. CBA believes the ensuing negative effects on consumers of the debit interchange regulation will highlight the harm of governmental price fixing, making it difficult to produce any successful legislative or regulatory efforts that seek to do further harm to interchange rates.
