Question

When consumers swipe a card, either debit or credit, to make a transaction with a merchant, the merchant pays an interchange fee to the card-issuing bank. Generally, the interchange fee for a debit card is 1% of the purchase amount, while for a credit card it is 1.6% of the purchase amount. In 2009, the average interchange fee was 44 cents. In December 2010, the Federal Reserve proposed capping that interchange fee to 12 cents per transaction. Who are the three primary stakeholders in this proposal, and what do you predict their positions will be relative to this proposal?
